    OBJECTIVE: To compare the effects of two antihypertensive treatment strategies for the prevention of coronary heart disease and other cardiovascular events in the large subpopulation (n=5137) with diabetes mellitus in the blood pressure-lowering arm of the Anglo-Scandinavian Cardiac Outcomes Trial....... METHODS: Patients had either untreated hypertension or treated hypertension. For those with type II diabetes mellitus, inclusion criteria required at least two additional risk factors. Patients were randomized to amlodipine with addition of perindopril as required (amlodipine-based) or atenolol...... with addition of thiazide as required (atenolol-based). Therapy was titrated to achieve a target blood pressure of less than 130/80 mmHg. RESULTS: The trial was terminated early due to significant benefits on mortality and stroke associated with the amlodipine-based regimen. In patients with diabetes mellitus...

    Excess pressure integral (XSPI), a new index of surplus work performed by the left ventricle, can be calculated from blood pressure waveforms and may indicate circulatory dysfunction. We investigated whether XSPI predicted future cardiovascular events and target organ damage in treated hypertensive individuals. Radial blood pressure waveforms were acquired by tonometry in 2069 individuals (aged, 63±8 years) in the Conduit Artery Functional Evaluation (CAFE) substudy of the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT). Measurements of left ventricular mass index (n=862) and common carotid artery intima media thickness (n=923) were also performed. XSPI and the integral of reservoir pressure were lower in people treated with amlodipine±perindopril than in those treated with atenolol±bendroflumethiazide, although brachial systolic blood pressure was similar. A total of 134 cardiovascular events accrued during a median 3.4 years of follow-up; XSPI was a significant predictor of cardiovascular events after adjustment for age and sex, and this relationship was unaffected by adjustment for conventional cardiovascular risk factors or Framingham risk score. XSPI, central systolic blood pressure, central augmentation pressure, central pulse pressure, and integral of reservoir pressure were correlated with left ventricular mass index, but only XSPI, augmentation pressure, and central pulse pressure were associated positively with carotid artery intima media thickness. Associations between left ventricular mass index, XSPI, and integral of reservoir pressure and carotid artery intima media thickness and XSPI were unaffected by multivariable adjustment for other covariates. XSPI is a novel indicator of cardiovascular dysfunction and independently predicts cardiovascular events and targets organ damage in a prospective clinical trial. © 2014 American Heart Association, Inc.

    In this study, we aimed to translate the average relative effect of statin therapy from trial data to the individual patient with type 2 diabetes mellitus by developing and validating a model to predict individualized absolute risk reductions (ARR) of cardiovascular events. Data of 2725 patients with type 2 diabetes mellitus from the Lipid Lowering Arm of the Anglo Scandinavian Cardiac Outcomes Trial (ASCOT-LLA) study (atorvastatin 10 mg versus placebo) were used for model derivation. The model was based on 8 clinical predictors including treatment allocation (statin/placebo). Ten-year individualized ARR on major cardiovascular events by statin therapy were calculated for each patient by subtracting the estimated on-treatment risk from the estimated off-treatment risk. Predicted 10-year ARR by statin therapy was 4% (median ARR, 3.2%; interquartile range, 2.5%-4.3%; 95% confidence interval for 3.2% ARR, -1.4% to 6.8%). Addition of treatment interactions did not improve model performance. Therefore, the wide distribution in ARR was a consequence of the underlying distribution in cardiovascular risk enrolled in these trials. External validation of the model was performed in data from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT-LLT; pravastatin 40 mg versus usual care) and Collaborative Atorvastatin Diabetes Study (CARDS; atorvastatin 10 mg versus placebo) of 3878 and 2838 patients with type 2 diabetes mellitus, respectively. Model calibration was adequate in both external data sets, discrimination was moderate (ALLHAT-LLT: c-statistics, 0.64 [95% confidence interval, 0.61-0.67] and CARDS: 0.68 [95% confidence interval, 0.64-0.72]). ARRs of major cardiovascular events by statin therapy can be accurately estimated for individual patients with type 2 diabetes mellitus using a model based on routinely available patient characteristics. There is a wide distribution in ARR that may complement informed decision making. URL: http

  15. Anglian and Anglo-Scandinavian Cottam: linking digital publication and archive

    2001-05-01

    Full Text Available The presence of Anglian and Anglo-Scandinavian settlements at Cottam, East Yorkshire, was first indicated in 1987 by numerous finds of copper alloy coins, dress pins and strap ends by metal detector users. This report presents the results of fieldwork carried out on behalf of the Department of Archaeology, University of York, between 1993-5, including field walking, geophysical survey, and excavation. This revealed an enclosure of the eighth-ninth centuries, containing traces of a small number of post-built halls. In the late ninth century this settlement was then abandoned, a process which led to the incorporation of a human female skull in a domestic rubbish pit. A new enclosed settlement was laid out nearby, which was occupied briefly in the early tenth century. It is argued that the Anglian settlement may have been part of a royal multiple estate but that as a result of estate reorganisation after the Scandinavian settlement it developed into an independent manor. Cottam is the first so-called "productive site" in the environs of York to be the subject of archaeological investigations. The results suggest that it was a prosperous but not exceptional site, and that the primary activity was farming, with limited evidence for trade or manufacture. This work also prompts a reassessment of the typology of crop mark enclosures and the re-examination of the large number of undated enclosures in the area.

    Outcomes research is a quantitative assessment of the results of care. Outcomes analysis provides information that benefits the physician, the patient, the institution and the health care purchasers. It provides relevant and timely information for the assessment of the heart centre's performance. Outcomes data have proven to be useful to the attending physicians by providing a basis for clinical decision making. Patients may be appraised of the usual results and the risks of various treatment strategies and make informed decisions on their care. The purchasers of health care will be better informed regarding the costs and effectiveness of the care being delivered. O'Connor et al. have stated that methods of improving care are often discussed but are difficult to achieve due to processes of care being hidden from view. Outcomes research is a comprehensive performance evaluation strategy that may be used to discover the impact of these hidden aspects of care. This technology of the patient's experience is bringing cardiac surgery to a new level of excellence.

    To study the cardiac complications in diphtheria patients and to study the predictors of outcomes. Single centre prospective analysis of cardiac complications in diphtheria patients. In this study, there were 60 patients diagnosed with diphtheria with ECG changes. The ECG changes seen were sinus tachycardia (68.3%), T wave inversion (20%), ST segment depression (13.3%), right bundle branch block (5%), multiple atrial ectopics (3.3%). The case fatality rate in our study was 25% (15 patients). High CPK-MB, myoglobulin and cardiac troponin levels were associated with cardiac mortality. In our study, cardiac troponin T had the highest sensitivity (80%) and CK-MB had the highest specificity (95.56%). Cardiac involvement is a common complication of infection with C. diphtheria and is associated with high mortality. As diphtheria can be prevented by adequate vaccination, efforts should be maximized for high vaccine coverage with booster doses. Copyright © 2017. Published by Elsevier B.V.

    OBJECTIVE: To test serum tau as a predictor of neurological outcome after cardiac arrest. METHODS: We measured the neuronal protein tau in serum at 24, 48, and 72 hours after cardiac arrest in 689 patients in the prospective international Target Temperature Management trial. The main outcome...... was poor neurological outcome, defined as Cerebral Performance Categories 3-5 at 6 months. RESULTS: Increased tau was associated with poor outcome at 6 months after cardiac arrest (median = 38.5, interquartile range [IQR] = 5.7-245ng/l in poor vs median = 1.5, IQR = 0.7-2.4ng/l in good outcome, for tau....... The accuracy in predicting outcome by serum tau was equally high for patients randomized to 33 °C and 36 °C targeted temperature after cardiac arrest. INTERPRETATION: Serum tau is a promising novel biomarker for prediction of neurological outcome in patients with cardiac arrest. It may be significantly better...

    Cardiac injuries are one of the most challenging injuries in the field of trauma surgery. Their management often requires immediate surgical intervention, excellent surgical technique and the ability to provide excellent postoperative critical care to patients. The aim of this study was to evaluate the outcome and survival rate of patients with penetrating cardiac injury in southern Iran, Shiraz. From January 2001 to June 2007, medical records of all patients suffering from penetrating cardiac injuries were reviewed and their outcomes were investigated. The inclusion criterion was the presence of a confirmed penetrating cardiac injury intraoperatively or by autopsy. Patients with blunt cardiac injuries were excluded from the study. The study consisted of 37 patients, including 1 gunshot wound (2.7%), 35 stab wounds (94.6%) and 1 (2.7%) shotgun wound. The overall survival rate was 76% (28 in 37) and that in stab wound patients was 80%. The collected data of 9 expired patients revealed 11% death on arrival, 67% hypotensive, and 22% normotensive considering physiologic presentation. Paired sample test showed significant correlation between mortality and electrocardiographic changes, amount of retained blood in pericardium, clinical stage and physiologic condition at presentation, as well as associated injury type (gunshot more than stab wound). Our results show that injury mechanism and initial cardiac rhythm are significant predictors of outcomes in patients with penetrating cardiac injuries. Besides, gunshot injury and exsanguination are the most important predictive variables of mortality.

The objective was to compare the characteristics and outcome of cardiac asthma with that of classical congestive heart failure (CHF in elderly patients. Methods Prospective study in an 1,800-bed teaching hospital. Results Two hundred and twelve consecutive patients aged ≥ 65 years presenting with dyspnea due to CHF (mean age of 82 ± 8 years were included. Findings of cardiac echocardiography and natriuretic peptides levels were used to confirm CHF. Cardiac asthma patients were defined as a patient with CHF and wheezing reported by attending physician upon admission to the emergency department. The CHF group (n = 137 and the cardiac asthma group (n = 75, differed for tobacco use (34% vs. 59%, p 2 (47 ± 15 vs. 41 ± 11 mmHg, p Conclusion Patients with cardiac asthma represented one third of CHF in elderly patients.

    Full Text Available Abstract Background Canadian trauma units have relatively little experience with major cardiac trauma (disruption of a cardiac chamber so injury outcome may not be comparable to that reported from other countries. We compared our outcomes to those of other centers. Methods Records of patients suffering major cardiac trauma over a nine-year period were reviewed. Factors predictive of outcome were analyzed. Results Twenty-seven patients (11 blunt and 16 penetrating with major cardiac trauma were evaluated. Injury severity scores (ISS were similar for blunt (49.6 ± 16.6 and penetrating (39.5 ± 21.6, p = 0.20 injuries. Five of 11 blunt trauma patients, and 9 of 16 penetrating trauma patients, had detectable vital signs on hospital arrival (p = 0.43. Ten patients underwent emergency department thoracotomy and 11 patients had cardiac repair in the operating theatre. Eleven patients survived and 16 died. Survivors had a lower ISS (33.7 ± 15.4 than non-survivors (50.4 ± 20.4; p = 0.03. Two of 11 blunt trauma patients and 9 of 16 penetrating trauma patients survived (p = 0.06. Eleven of 14 patients with detectable vital signs survived; all 13 without detectable vital signs died (p = 0.00003. Ten of eleven patients treated in the operating theatre survived, while only one of the other 16 patients survived (p = 0.00002. Conclusions Patients with major cardiac injuries and detectable vital signs on hospital arrival can be salvaged by prompt surgical intervention in the operating theatre. Major cardiac injuries are infrequently encountered at our center but patient survival is comparable to that reported from trauma units in other countries.

    Eitezaz Mahmood

    Full Text Available Despite showing a prognostic value in general surgical patients, preoperative asymptomatic elevated white blood cell (WBC count is not considered a risk factor for cardiac surgery. Whereas there is sporadic evidence of its value as a preoperative risk marker, it has not been looked at methodically as a specific index of outcome during cardiac surgery. Using a national database we sought to determine the relationship between preoperative WBC count and postoperative outcome in cardiac surgical patients.Cardiac surgeries were extracted from the 2007-2013 American College of Surgeons National Surgical Quality Improvement Program database. Leukocytosis was defined by a preoperative WBC count greater than 11,000 cells/μL. A univariate analysis compared the incidence of adverse outcomes for patients with and without leukocytosis. A multivariate logistic regression model was constructed in order to test whether leukocytosis was an independent predictor of morbidity and mortality.Out of a total of 10,979 cardiac surgery patients 863 (7.8% had preoperative leukocytosis. On univariate analysis, patients with leukocytosis experienced greater incidences of 30-day mortality, wound complications, and medical complications. Wound complications included surgical site infection as well as wound dehiscence. The medical complications included all other non-surgical causes of increased morbidity and infection leading to urinary tract infection, pneumonia, ventilator dependence, sepsis and septic shock. After stepwise model adjustment, leukocytosis was a strong predictor of medical complications (OR 1.22, 95% CI: 1.09-1.36, p = 0.002 with c-statistic of 0.667. However, after stepwise model adjustment leukocytosis was not a significant predictor of 30-day mortality and wound complications.Preoperative leukocytosis is associated with adverse postoperative outcome after cardiac surgery and is an independent predictor of infection-related postoperative complications.

    Purpose: Adjuvant radiation therapy, which has proven benefit against breast cancer, has historically been associated with an increased incidence of ischemic heart disease. Modern techniques have reduced this risk, but a detailed evaluation has not recently been conducted. The present study evaluated the effect of current radiation practices on ischemia-related cardiac events and procedures in a population-based study of older women with nonmetastatic breast cancer. Methods and Materials: A total of 29,102 patients diagnosed from 2000 to 2009 were identified from the Surveillance, Epidemiology, and End Results–Medicare database. Medicare claims were used to identify the radiation therapy and cardiac outcomes. Competing risk models were used to assess the effect of radiation on these outcomes. Results: Patients with left-sided breast cancer had a small increase in their risk of percutaneous coronary intervention (PCI) after radiation therapy—the 10-year cumulative incidence for these patients was 5.5% (95% confidence interval [CI] 4.9%-6.2%) and 4.5% (95% CI 4.0%-5.0%) for right-sided patients. This risk was limited to women with previous cardiac disease. For patients who underwent PCI, those with left-sided breast cancer had a significantly increased risk of cardiac mortality with a subdistribution hazard ratio of 2.02 (95% CI 1.23-3.34). No other outcome, including cardiac mortality for the entire cohort, showed a significant relationship with tumor laterality. Conclusions: For women with a history of cardiac disease, those with left-sided breast cancer who underwent radiation therapy had increased rates of PCI and a survival decrement if treated with PCI. The results of the present study could help cardiologists and radiation oncologists better stratify patients who need more aggressive cardioprotective techniques.

The present study evaluated the effect of current radiation practices on ischemia-related cardiac events and procedures in a population-based study of older women with nonmetastatic breast cancer. Methods and Materials: A total of 29,102 patients diagnosed from 2000 to 2009 were identified from the Surveillance, Epidemiology, and End Results–Medicare database. Medicare claims were used to identify the radiation therapy and cardiac outcomes. Competing risk models were used to assess the effect of radiation on these outcomes. Results: Patients with left-sided breast cancer had a small increase in their risk of percutaneous coronary intervention (PCI) after radiation therapy—the 10-year cumulative incidence for these patients was 5.5% (95% confidence interval [CI] 4.9%-6.2%) and 4.5% (95% CI 4.0%-5.0%) for right-sided patients. This risk was limited to women with previous cardiac disease. For patients who underwent PCI, those with left-sided breast cancer had a significantly increased risk of cardiac mortality with a subdistribution hazard ratio of 2.02 (95% CI 1.23-3.34). No other outcome, including cardiac mortality for the entire cohort, showed a significant relationship with tumor laterality. Conclusions: For women with a history of cardiac disease, those with left-sided breast cancer who underwent radiation therapy had increased rates of PCI and a survival decrement if treated with PCI. The results of the present study could help cardiologists and radiation oncologists better stratify patients who need more aggressive cardioprotective techniques.

    Cardiac rupture following blunt thoracic trauma is rarely encountered by clinicians, since it commonly causes death at the scene. With advances in traumatology, blunt cardiac rupture had been increasingly disclosed in various ways. This study reviews our experience of patients with suspected blunt traumatic cardiac rupture and proposes treatment protocols for the same. This is a 5-year retrospective study of trauma patients confirmed with blunt traumatic cardiac rupture admitted to a university-affiliated tertiary trauma referral centre. The following information was collected from the patients: age, sex, mechanism of injury, initial effective diagnostic tool used for diagnosing blunt cardiac rupture, location and size of the cardiac injury, associated injury and injury severity score (ISS), reversed trauma score (RTS), survival probability of trauma and injury severity scoring (TRISS), vital signs and biochemical lab data on arrival at the trauma centre, time elapsed from injury to diagnosis and surgery, surgical details, hospital course and final outcome. The study comprised 8 men and 3 women with a median age of 39 years (range: 24-73 years) and the median follow-up was 5.5 months (range: 1-35 months). The ISS, RTS, and TRISS scores of the patients were 32.18+/-5.7 (range: 25-43), 6.267+/-1.684 (range: 2.628-7.841), and 72.4+/-25.6% (range: 28.6-95.5%), respectively. Cardiac injuries were first detected using focused assessment with sonography for trauma (FAST) in 4 (36.3%) patients, using transthoracic echocardiography in 3 (27.3%) patients, chest CT in 1 (9%) patient, and intra-operatively in 3 (27.3%) patients. The sites of cardiac injury comprised the superior vena cava/right atrium junction (n=4), right atrial auricle (n=1), right ventricle (n=4), left ventricular contusion (n=1), and diffuse endomyocardial dissection over the right and left ventricles (n=1). Notably, 2 had pericardial lacerations presenting as a massive haemothorax, which initially masked

    Guidelines for cardiopulmonary resuscitation recommend a chest compression rate of at least 100 compressions per minute. Animal and human studies have reported that blood flow is greatest with chest compression rates near 120/min, but few have reported rates used during out-of-hospital (OOH) cardiopulmonary resuscitation or the relationship between rate and outcome. The purpose of this study was to describe chest compression rates used by emergency medical services providers to resuscitate patients with OOH cardiac arrest and to determine the relationship between chest compression rate and outcome. Included were patients aged ≥ 20 years with OOH cardiac arrest treated by emergency medical services providers participating in the Resuscitation Outcomes Consortium. Data were abstracted from monitor-defibrillator recordings during cardiopulmonary resuscitation. Multiple logistic regression analysis assessed the association between chest compression rate and outcome. From December 2005 to May 2007, 3098 patients with OOH cardiac arrest were included in this study. Mean age was 67 ± 16 years, and 8.6% survived to hospital discharge. Mean compression rate was 112 ± 19/min. A curvilinear association between chest compression rate and return of spontaneous circulation was found in cubic spline models after multivariable adjustment (P=0.012). Return of spontaneous circulation rates peaked at a compression rate of ≈ 125/min and then declined. Chest compression rate was not significantly associated with survival to hospital discharge in multivariable categorical or cubic spline models. Chest compression rate was associated with return of spontaneous circulation but not with survival to hospital discharge in OOH cardiac arrest.

    To examine survival rates for paediatric trauma patients requiring cardiopulmonary resuscitation (CPR) in the pre-hospital setting, and to identify characteristics that may be associated with survival. Ten-year retrospective trauma database review. An urban physician-led pre-hospital trauma service serving a population of approximately 7.5 million, in the United Kingdom. Eighty paediatric trauma patients (15 years or less) who received pre-hospital resuscitation following cardiorespiratory arrest between July 1994 and June 2004. Pre-hospital cardiopulmonary resuscitation. Survival to hospital discharge. Eighty children met inclusion criteria for the study. Nineteen (23.8%) were discharged alive from the emergency department and seven children (8.75%) survived to hospital discharge. Of the seven survivors, one had spinal cord injury. Two suffered asphyxial injury associated with blunt trauma and three sustained hypoxic insults following drowning or burns/smoke inhalation. In one patient with known congenital cardiac disease the cause of cardiac arrest was likely to have been medical. This study confirms the poor outcome for children requiring pre-hospital CPR following trauma. However, the results are better in this physician-attended group than in other studies where physicians were not present. They also suggest that cardiac arrest associated with trauma in children has a better outcome than in adults. In common with adults treated in this system, those patients with hypovolaemic cardiac arrest did not survive (Ann Emerg Med 2006;48:240-4). A large proportion of the survivors suffered hypoxic or asphyxial injuries. Targeted aggressive out-of-hospital resuscitation in certain patient groups can produce good outcomes.

    Full Text Available Introduction: Modulating the stress response and perioperative factors can have a paramount impact on the neurodevelopmental outcome of infants who undergo cardiac surgery utilizing cardiopulmonary bypass. Materials and Methods: In this single center prospective follow-up study, we evaluated the impact of three different anesthetic techniques on the neurodevelopmental outcomes of 19 children who previously underwent congenital cardiac surgery within their 1 st year of life. Cases were done from May 2011 to December 2013. Children were assessed using the Stanford-Binet Intelligence Scales (5 th edition. Multiple regression analysis was used to test different parental and perioperative factors that could significantly predict the different neurodevelopmental outcomes in the entire cohort of patients. Results: When comparing the three groups regarding the major cognitive scores, a high-dose fentanyl (HDF patients scored significantly higher than the low-dose fentanyl (LDF + dexmedetomidine (DEX (LDF + DEX group in the quantitative reasoning scores (106 ± 22 vs. 82 ± 15 P = 0.046. The bispectral index (BIS value at the end of surgery for the -LDF group was significantly higher than that in LDF + DEX group (P = 0.011. For the entire cohort, a strong correlation was seen between the standard verbal intelligence quotient (IQ score and the baseline adrenocorticotropic hormone level, the interleukin-6 level at the end of surgery and the BIS value at the end of the procedure with an R 2 value of 0.67 and P < 0.04. There was an inverse correlation between the cardiac Intensive Care Unit length of stay and the full-scale IQ score (R = 0.4675 and P 0.027. Conclusions: Patients in the HDF group demonstrated overall higher neurodevelopmental scores, although it did not reach statistical significance except in fluid reasoning scores. Our results may point to a possible correlation between blunting the stress response and improvement of the neurodevelopmental

    Cardiac myxomas are the most frequent primary benign intracardiac tumors. We reviewed our 27-year experience to evaluate factors associated with an embolism in patients with cardiac myxomas and their long-term outcomes. A retrospective review identified 99 patients with cardiac myxomas between 1985 and 2012. Tumors were divided into two groups based on their gross external features. Tumors with a smooth regular border and a solid consistency were classified as solid; papillary myxomas were characterized by an irregular and gelatinous exterior with friable, soft consistency. The patients were classified into embolic and non-embolic groups to focus on embolic events. Mean age at surgery was 49.8 ± 16 years. There were 92 left atrial myxomas (92.9%) . Embolization was observed in 25 patients (25.3%) before surgery. Three variables were associated with an embolic event, small tumor size (odds ratio [OR] = 4.36 P = 0.037 confidence interval [CI] 95% 0.534-0.980), atrial fibrillation (OR = 10.119 P = 0.001 CI 95% 0.021-0.397), and papillary-type pathology (OR = 11.544 P = 0.001 CI 95% 0.033-0.399). Tumor pathology or the presence of embolization prior to surgery had no effect on operative mortality or long-term survival. Embolization of cardiac myxomas is more likely to occur in papillary-type tumors, that are smaller in size and in patients presenting with preoperative atrial fibrillation. However, the presence of embolization at the time of surgery does not increase operative morbidity or mortality or affect long-term survival. © 2017 Wiley Periodicals, Inc.

    Although single individual reports have documented outcomes in children with pentalogy of are few data available for postoperative outcome of this cohort of patients after cardiac surgery. The aim of this study was to retrospectively review the clinical details of patients with pentalogy of Cantrell managed at two centers. Two cardiac surgical institutions retrospectively studied all patients with pentalogy of Cantrell and significant congenital heart disease who underwent surgical intervention, excluding PDA ligation, between 1992 and 2004. Seven children with pentalogy of Cantrell underwent surgical intervention at a median age of 60 days (range, 1-11 months). Three patients had tetralogy of Fallot, two double outlet right ventricle, one patient had tricuspid atresia, and one patient a perimembranous ventricular septal defect. The mean duration of postoperative ventilation was 112.8 days (range, 4-335 days) but three patients required ventilation for more than 100 days. Patients who had a preoperative diaphragmatic plication required a longer duration of ventilation (mean = 186.5 days [range, 100-273 days] compared with mean = 132 days [range, 4-335 days]). Four patients survived, with three patients weaned from ventilation. Three patients had withdrawal of care following failure to wean from ventilation, following multisystem organ failure, and at the request of their parents. In conclusion, the postoperative care of children with pentalogy of Cantrell after cardiac surgery is often complicated by prolonged need for ventilatory support and multiple postoperative complications. Earlier surgical intervention does not necessarily reduce morbidity and mortality. These data may help in the counseling of parents prior to surgical intervention.

    The objectives of this follow-up study of 292 fetuses with various cardiac arrhythmias were to estimate the incidence of structural heart defects and fetal compromise, to investigate the effects of antiarrhythmic medication, and to evaluate perinatal mortality and morbidity and long-term outcome. The arrhythmias were classified into atrial extrasystoles (n = 200), atrial tachycardias (n = 35), atrioventricular block (n = 36), sinus bradycardia (n = 14), and ventricular extrasystoles (n = 7), and outcome of the infants was analyzed. The incidence of cardiac anomalies was 12% in the study population. In utero cardiac failure was noted in 11%. Among fetuses with atrial extrasystoles, 1% developed supraventricular tachycardia after birth. During antiarrhythmic therapy, sinus rhythm was achieved in 92% of nonhydropic and in 63% of hydropic fetuses. The latter had higher mortality and risk for neurologic morbidity than did nonhydropic fetuses; 38% versus 3.7% and 40% versus 12%, respectively. Among fetuses with atrioventricular block only, the survival rate was 82%, with a heart defect, prognosis was poor: 50% survived. Sinus bradycardia and ventricular extrasystoles were associated with survival rates of 75% and 67%. In the follow-up of the whole study population lasting a median 5 years, 93% are alive and 3% have a neurologic disorder. All fetal arrhythmias except atrial extrasystoles were associated with a moderately high risk for fetal distress. In cases of compromise, fetal and neonatal prognosis was poor and was an indication for perinatal medication. After the newborn period, the prognosis has been good. However, the risk for neurologic morbidity must be taken into consideration.

    Although cardiac cancer of the remnant stomach and primary cardiac cancer both occur in the same position, their clinical characteristics and outcomes have not been compared previously. The objective of this study was designed to evaluate the prognosis of cardiac cancer of the remnant stomach in comparison with primary cardiac cancer. In this retrospective comparative study, clinical data and prognosis were compared in 48 patients with cardiac cancer of the remnant stomach and 96 patients with primary cardiac cancer who underwent radical resection from January 1995 to June 2007. Clinicopathologic characteristics, survival times, mortality, and complications were analyzed. The 5-year survival rate was significantly higher in patients with primary cardiac cancer than in those with cardiac cancer of the remnant stomach (28.4% vs. 16.7%, P = 0.035). Serosal invasion, lymph node metastasis and tumor location were independent prognostic factors for survival. Subgroup analysis, however, showed similar survival rates in patients with primary cardiac cancer and cardiac cancer of the remnant stomach without serosal invasion (25.0% vs. 43.8%, P = 0.214) and without lymph node metastasis (25.0% vs. 38.8%, P = 0.255), as well as similar complication rates (20.8% vs. 11.5%, P = 0.138). Although the survival rates after radical resection in patients with cardiac cancer of the remnant stomach were poorer than in those with primary cardiac cancer, they were similar in survival rates when patients without serosal invasion or lymph node metastasis. Therefore, early detection is an important way to improve overall survival in cardiac cancer of the remnant stomach.

    In-hospital cardiac arrest is an important public health problem. High-quality resuscitation improves survival but is difficult to achieve. Our objective is to evaluate the effectiveness of a novel, interdisciplinary, postevent quantitative debriefing program to improve survival outcomes after in-hospital pediatric chest compression events. Single-center prospective interventional study of children who received chest compressions between December 2008 and June 2012 in the ICU. Structured, quantitative, audiovisual, interdisciplinary debriefing of chest compression events with front-line providers. Primary outcome was survival to hospital discharge. Secondary outcomes included survival of event (return of spontaneous circulation for ≥ 20 min) and favorable neurologic outcome. Primary resuscitation quality outcome was a composite variable, termed "excellent cardiopulmonary resuscitation," prospectively defined as a chest compression depth ≥ 38 mm, rate ≥ 100/min, ≤ 10% of chest compressions with leaning, and a chest compression fraction > 90% during a given 30-second epoch. Quantitative data were available only for patients who are 8 years old or older. There were 119 chest compression events (60 control and 59 interventional). The intervention was associated with a trend toward improved survival to hospital discharge on both univariate analysis (52% vs 33%, p = 0.054) and after controlling for confounders (adjusted odds ratio, 2.5; 95% CI, 0.91-6.8; p = 0.075), and it significantly increased survival with favorable neurologic outcome on both univariate (50% vs 29%, p = 0.036) and multivariable analyses (adjusted odds ratio, 2.75; 95% CI, 1.01-7.5; p = 0.047). Cardiopulmonary resuscitation epochs for patients who are 8 years old or older during the debriefing period were 5.6 times more likely to meet targets of excellent cardiopulmonary resuscitation (95% CI, 2.9-10.6; p < 0.01). Implementation of an interdisciplinary, postevent quantitative debriefing

    Cardiac resynchronization therapy (CRT) has been shown to be effective for patients with chronic heart failure; however, the efficacy of CRT in patients with cardiac sarcoidosis (CS) has not been established. We compared the outcomes of patients with CS who received CRT to patients with dilated cardiomyopathy (DCM). The incidence of major adverse cerebral and cardiovascular events (MACCE) in 11 consecutive CS patients (8 females; mean age, 66 ± 8.0 years) who received CRT were compared with 29 DCM patients (9 females; mean age, 70 ± 8.9 years). Females and patients with previous right ventricular pacing were largely included in the comparison of CS and DCM patients (P < 0.05 and P < 0.0001, respectively). During the mean follow-up period (465 ± 383 days for CS and 729 ± 393 days for DCM), MACCE were evident in 9 patients (23%); specifically, 5 CS and 4 DCM patients developed MACCE (45% vs. 14%, P < 0.05), respectively. Kaplan-Meier survival analysis demonstrated that CS patients had a higher prevalence of MACCE than DCM patients (log rank = 6.306, P = 0.0120; and Wilcoxon = 7.1333, P = 0.0076). Based on univariate analysis, the etiology of CS was associated with MACCE. Our results suggest that the long-term outcome of CRT in patients with CS was very poor compared with DCM patients. Thus, caution should be exercised regarding the indication of CRT in patients with CS. © 2016 Wiley Periodicals, Inc.

    Full Text Available Post-ischemic changes in cellular metabolism alter myocardial and neurological function. Pyruvate dehydrogenase (PDH, the limiting step in mitochondrial glucose oxidation, is inhibited by increased expression of PDH kinase (PDK during ischemia/reperfusion injury. This results in decreased utilization of glucose to generate cellular ATP. Post-cardiac arrest (CA hypothermia improves outcomes and alters metabolism, but its influence on PDH and PDK activity following CA are unknown. We hypothesized that therapeutic hypothermia (TH following CA is associated with the inhibition of PDK activity and increased PDH activity. We further hypothesized that an inhibitor of PDK activity, dichloroacetate (DCA, would improve PDH activity and post-CA outcomes.Anesthetized and ventilated adult female C57BL/6 wild-type mice underwent a 12-minute KCl-induced CA followed by cardiopulmonary resuscitation. Compared to normothermic (37°C CA controls, administering TH (30°C improved overall survival (72-hour survival rate: 62.5% vs. 28.6%, P<0.001, post-resuscitation myocardial function (ejection fraction: 50.9±3.1% vs. 27.2±2.0%, P<0.001; aorta systolic pressure: 132.7±7.3 vs. 72.3±3.0 mmHg, P<0.001, and neurological scores at 72-hour post CA (9.5±1.3 vs. 5.4±1.3, P<0.05.

    Congenital fetal cardiac anomalies compromise the most common group of fetal structural anomalies. Several previous reports analyzed all types of fetal cardiac anomalies together without individualized neonatal morbidity outcomes based on cardiac defect. Mode of delivery in cases of fetal cardiac anomalies varies greatly as optimal mode of delivery in these complex cases is unknown. We sought to determine rates of neonatal outcomes for fetal cardiac anomalies and examine the role of attempted route of delivery on neonatal morbidity. Gravidas with fetal cardiac anomalies and delivery >34 weeks, excluding stillbirths and aneuploidies (n = 2166 neonates, n = 2701 cardiac anomalies), were analyzed from the Consortium on Safe Labor, a retrospective cohort study of electronic medical records. Cardiac anomalies were determined using International Classification of Diseases, Ninth Revision codes and organized based on morphology. Neonates were assigned to each cardiac anomaly classification based on the most severe cardiac defect present. Neonatal outcomes were determined for each fetal cardiac anomaly. Composite neonatal morbidity (serious respiratory morbidity, sepsis, birth trauma, hypoxic ischemic encephalopathy, and neonatal death) was compared between attempted vaginal delivery and planned cesarean delivery for prenatal and postnatal diagnosis. We used multivariate logistic regression to calculate adjusted odds ratio for composite neonatal morbidity controlling for race, parity, body mass index, insurance, gestational age, maternal disease, single or multiple anomalies, and maternal drug use. Most cardiac anomalies were diagnosed postnatally except hypoplastic left heart syndrome, which had a higher prenatal than postnatal detection rate. Neonatal death occurred in 8.4% of 107 neonates with conotruncal defects. Serious respiratory morbidity occurred in 54.2% of 83 neonates with left ventricular outflow tract defects. Overall, 76.3% of pregnancies with fetal

    Whether remote ischemic preconditioning (transient ischemia and reperfusion of the arm) can improve clinical outcomes in patients undergoing coronary-artery bypass graft (CABG) surgery is not known. We investigated this question in a randomized trial. We conducted a multicenter, sham-controlled trial involving adults at increased surgical risk who were undergoing on-pump CABG (with or without valve surgery) with blood cardioplegia. After anesthesia induction and before surgical incision, patients were randomly assigned to remote ischemic preconditioning (four 5-minute inflations and deflations of a standard blood-pressure cuff on the upper arm) or sham conditioning (control group). Anesthetic management and perioperative care were not standardized. The combined primary end point was death from cardiovascular causes, nonfatal myocardial infarction, coronary revascularization, or stroke, assessed 12 months after randomization. We enrolled a total of 1612 patients (811 in the control group and 801 in the ischemic-preconditioning group) at 30 cardiac surgery centers in the United Kingdom. There was no significant difference in the cumulative incidence of the primary end point at 12 months between the patients in the remote ischemic preconditioning group and those in the control group (212 patients [26.5%] and 225 patients [27.7%], respectively; hazard ratio with ischemic preconditioning, 0.95; 95% confidence interval, 0.79 to 1.15; P=0.58). Furthermore, there were no significant between-group differences in either adverse events or the secondary end points of perioperative myocardial injury (assessed on the basis of the area under the curve for the high-sensitivity assay of serum troponin T at 72 hours), inotrope score (calculated from the maximum dose of the individual inotropic agents administered in the first 3 days after surgery), acute kidney injury, duration of stay in the intensive care unit and hospital, distance on the 6-minute walk test, and quality of life

The objective of this study was to evaluate the epidemiology of cardiac arrest and mortality after cardiac arrest among critically ill children with and without Down Syndrome. Patients ≤18 years admitted at a Pediatric Health Information Systems (PHIS) participating Intensive Care Unit were included (2004-2014). Multivariable logistic regression models were fitted to evaluate association of Down Syndrome with study outcomes after adjusting for patient and center characteristics. A total of 849,250 patients from 44 centers were included. Of the 25,143 patients with Down Syndrome, cardiac arrest was noted among 568 (2.3%) patients with an associated mortality at hospital discharge of 248 (43.6%) patients. In contrast, of the 824,107 patients without Down Syndrome, cardiac arrest was noted among 15,822 (1.9%) patients with an associated mortality at hospital discharge of 7775 (49.1%) patients. In adjusted models, patients with Down Syndrome had a higher likelihood of having cardiac arrest as compared to patients without Down Syndrome (with vs. without Down, OR: 1.14, 95% CI: 1.03-1.25, P=0.01). Despite having a higher likelihood of cardiac arrest, patients with Down Syndrome were associated with a lower mortality after cardiac arrest (OR: 0.78, 95% CI: 0.63-0.96, P=0.02). Both incidence of cardiac arrest, and mortality at hospital discharge in those with cardiac arrest vary substantially in children with and without Down Syndrome.

    Small studies suggest that children experiencing a cardiac arrest after undergoing cardiac surgery have better outcomes than other groups of patients, but the survival outcomes and periarrest variables of cardiac and noncardiac pediatric patients have not been compared. All cardiac arrests in patients <18 years of age were identified from Get With the Guidelines-Resuscitation from 2000 to 2008. Cardiac arrests occurring in the neonatal intensive care unit were excluded. Of 3323 index cardiac arrests, 19% occurred in surgical-cardiac, 17% in medical-cardiac, and 64% in noncardiac (trauma, surgical-noncardiac, and medical-noncardiac) patients. Survival to hospital discharge was significantly higher in the surgical-cardiac group (37%) compared with the medical-cardiac group (28%; adjusted odds ratio, 1.8; 95% confidence interval, 1.3-2.5) and the noncardiac group (23%; adjusted odds ratio, 1.8; 95% confidence interval, 1.4-2.4). Those in the cardiac groups were younger and less likely to have preexisting noncardiac organ dysfunction, but were more likely to have ventricular arrhythmias as their first pulseless rhythm, to be monitored and hospitalized in the intensive care unit at the time of cardiac arrest, and to have extracorporeal cardiopulmonary resuscitation compared with those in the noncardiac group. There was no survival advantage for patients in the medical-cardiac group compared with those in the noncardiac group when adjusted for periarrest variables. Children with surgical-cardiac disease have significantly better survival to hospital discharge after an in-hospital cardiac arrest compared with children with medical-cardiac disease and noncardiac disease.

    Full Text Available BACKGROUND: Cystic echinococcosis (CE can affect the heart and the vena cava but few cases are reported. METHODS: A retrospective case series of 11 patients with cardiac and/or endovascular CE, followed-up over a period of 15 years (1995-2009 is reported. RESULTS: Main clinical manifestations included thoracic pain or dyspnea, although 2 patients were asymptomatic. Cysts were located mostly in the right atrium and inferior vena cava. Nine patients were previously diagnosed with disseminated CE. Echocardiography was the diagnostic method of choice, although serology, electrocardiogram, chest X-ray, computed tomography/magnetic resonance imaging and histology aided with diagnosis and follow-up. Nine patients underwent cardiac surgery and nine received long-term antiparasitic treatment for a median duration of 25 months (range 4-93 months. One patient died intra-operatively due to cyst rupture and endovascular dissemination. Two patients died 10 and 14 years after diagnosis, due to pulmonary embolism (PE and cardiac failure, respectively. One patient was lost to follow-up. Patients who had cardiac involvement exclusively did not have complications after surgery and were considered cured. There was only one recurrence requiring a second operation. Patients with vena cava involvement developed PEs and presented multiple complications. CONCLUSIONS: Cardiovascular CE is associated with a high risk of potentially lethal complications. Clinical manifestations and complications vary according to cyst location. Isolated cardiac CE may be cured after surgery, while endovascular extracardiac involvement is associated with severe chronic complications. CE should be included in the differential diagnosis of cardiovascular disease in patients from endemic areas.

    We studied rapid response events after acute clinical instability outside ICU settings in pediatric cardiac patients. Our objective was to describe the characteristics and outcomes after rapid response events in this high-risk cohort and elucidate the cardiac conditions and risk factors associated with worse outcomes. A retrospective single-center study was carried out over a 3-year period from July 2011 to June 2014. Referral high-volume pediatric cardiac center located within a tertiary academic pediatric hospital. All rapid response events that occurred during the study period were reviewed to identify rapid response events in cardiac patients. None. We reviewed 1,906 rapid response events to identify 152 rapid response events that occurred in 127 pediatric cardiac patients. Congenital heart disease was the baseline diagnosis in 74% events (single ventricle, 28%; biventricle physiology, 46%). Seventy-four percent had a cardiac surgery before rapid response, 37% had ICU stay within previous 7 days, and acute kidney injury was noted in 41% post rapid response. Cardiac and/or pulmonary arrest occurred during rapid response in 8.5%. Overall, 81% were transferred to ICU, 22% had critical deterioration (ventilation or vasopressors within 12 hr of transfer), and 56% received such support and/or invasive procedures within 72 hours. Mortality within 30 days post event was 14%. Significant outcome associations included: single ventricle physiology-increased need for invasive procedures and mortality (adjusted odds ratio, 2.58; p = 0.02); multiple rapid response triggers-increased ICU transfer and interventions at 72 hours; critical deterioration-cardiopulmonary arrest and mortality; and acute kidney injury-cardiopulmonary arrest and need for hemodynamic support. Congenital heart disease, previous cardiac surgery, and recent discharge from ICU were common among pediatric cardiac rapid responses.

    Patient survival after cardiac arrest can be improved significantly with prompt and effective resuscitative care. This systematic review analyzes the basic life support factors that improve survival outcome, including chest compression technique and rapid defibrillation of shockable rhythms. For patients who are successfully resuscitated, comprehensive postresuscitation care is essential. Targeted temperature management is recommended for all patients who remain comatose, in addition to careful monitoring of oxygenation, hemodynamics, and cardiac rhythm. Management of cardiac arrest in circumstances such as pregnancy, pulmonary embolism, opioid overdose and other toxicologic causes, hypothermia, and coronary ischemia are also reviewed.

    Health care is evolving into a value-based reimbursement system focused on quality and outcomes. Reported outcomes from national databases are used for quality improvement projects and public reporting. This study compared reported outcomes in cardiac and thoracic surgery from two validated reporting databases—the Society of Thoracic Surgeons (STS) database and the National Surgical Quality Improvement Program (NSQIP)—from January 2011 to June 2012. Quality metrics and outcomes included mortality, wound infection, prolonged ventilation, pneumonia, renal failure, stroke, and cardiac arrest. Comparison was made by chi-square analysis. A total of 737 and 177 cardiac surgery cases and 451 and 105 thoracic surgery cases were captured by the STS database and NSQIP, respectively. Within cardiac surgery, there was a statistically significant difference in the reported rates of prolonged ventilation, renal failure, and mortality. No significant differences were found for the thoracic surgery data. In conclusion, our data indicated a significant discordance in quality reporting for cardiac surgery between the NSQIP and the STS databases. The disparity between databases and duplicate participation strongly indicates that a unified national quality reporting program is required. Consolidation of reporting databases and standardization of morbidity definitions across all databases may improve participation and reduce hospital cost. PMID:25552787

    Abstract: Most cardiac units achieve excellent results today, but the risk of cardiac surgery is still relatively high, and avoidable harm is common. The story of the Green Lane Cardiothoracic Unit provides an exemplar of excellence, but also illustrates the challenges associated with changes over time and with increases in the size of a unit and the complexity of practice today. The ultimate aim of cardiac surgery should be the best outcomes for (often very sick) patients rather than an undue focus on the prevention of error or adverse events. Measurement is fundamental to improving quality in health care, and the framework of structure, process, and outcome is helpful in considering how best to achieve this. A combination of outcomes (including some indicators of important morbidity) with key measures of process is advocated. There is substantial evidence that failures in teamwork and communication contribute to inefficiency and avoidable harm in cardiac surgery. Minor events are as important as major ones. Six approaches to improving teamwork (and hence outcomes) in cardiac surgery are suggested. These are: 1) subspecialize and replace tribes with teams; 2) sort out the leadership while flattening the gradients of authority; 3) introduce explicit training in effective communication; 4) use checklists, briefings, and debriefings and engage in the process; 5) promote a culture of respect alongside a commitment to excellence and a focus on patients; 6) focus on the performance of the team, not on individuals.

    Full Text Available Perioperative and postoperative morbidity and mortality associated with cardiac surgery affect both the outcome and quality of life. Markers such as troponin effectively predict short-term outcome. In a prospective cohort study in a University Hospital we assessed the role of cardiac biomarkers, also as predictors of long-term outcome and life quality after cardiac surgery with a three-year follow-up after conventional heart surgery. Patients were interviewed via phone calls with a structured questionnaire examining general health, functional status, activities of daily living, perception of life quality and need for hospital readmission. Descriptive statistics and multivariate analysis were performed. Out of 252 consecutive patients, 8 (3.2% died at the three years follow up: 7 for cardiac complications and 1 for cancer. Thirty-six patients (13.5% had hospital readmission for cardiac causes (mostly for atrial fibrillation or other arrhythmias (9.3%, but none needed cardiac surgical reintervention; 21 patients (7.9% were hospitalised for non-cardiac causes. No limitation in function activities of daily living was reported by most patients (94%, 92% perceived their general health as excellent, very good or good and none considered it insufficient; 80% were NYHA I, 17% NYHA II, 3% NYHA III and none NYHA IV. Multivariate analysis indicated preoperative treatment with digitalis or nitrates, and postoperative cardiac biomarkers release was independently associated to death. Elevated cardiac biomarker release and length of hospital stay were the only postoperative independent predictors of death in this study.

    Background and objectives Preoperative anemia adversely affects outcomes of cardiothoracic surgery. However, in patients with CKD, treating anemia to a target of normal hemoglobin has been associated with increased risk of adverse cardiac and cerebrovascular events. We investigated the association between preoperative hemoglobin and outcomes of cardiac surgery in patients with CKD and assessed whether there was a level of preoperative hemoglobin below which the incidence of adverse surgical outcomes increases. Design, setting, participants, & measurements This prospective observational study included adult patients with CKD stages 3–5 (eGFRpreoperative hemoglobin level: preoperative hemoglobin within the normal range (men: 14–18 g/dl; women: 12–16 g/dl). Univariate analysis revealed an inverse relationship between the incidence of all adverse postoperative outcomes and hemoglobin level. Using hemoglobin as a continuous variable, multivariate logistic regression analysis showed a proportionally greater frequency of all adverse postoperative outcomes per 1-g/dl decrement of preoperative hemoglobin (mortality: odds ratio, 1.38; 95% confidence interval, 1.23 to 1.57; Ppreoperative hemoglobinpreoperative anemia is associated with adverse postoperative outcomes in patients with CKD. Whether outcomes could be improved by therapeutically targeting higher preoperative hemoglobin levels before cardiac surgery in patients with underlying CKD remains to be determined. PMID:24993450

    Most scoring systems used to predict clinical outcome in critical care were not designed for application in cardiac surgery patients. To compare the predictive ability of the most widely used scoring systems (Acute Physiology and Chronic Health Evaluation [APACHE] II, Simplified Acute Physiology Score [SAPS] II, and Sequential Organ Failure Assessment [SOFA]) and of 2 specialized systems (European System for Cardiac Operative Risk Evaluation [EuroSCORE] II and the cardiac surgery score [CASUS]) for clinical outcome in patients after cardiac surgery. Consecutive patients admitted to a cardiac surgical intensive care unit (CSICU) were prospectively studied. Data on the preoperative condition, intraoperative parameters, and postoperative course were collected. EuroSCORE II, CASUS, and scores from 3 general severity-scoring systems (APACHE II, SAPS II, and SOFA) were calculated on the first postoperative day. Clinical outcome was defined as 30-day mortality and in-hospital morbidity. A total of 150 patients were included. Thirty-day mortality was 6%. CASUS was superior in outcome prediction, both in relation to discrimination (area under curve, 0.89) and calibration (Brier score = 0.043, χ(2) = 2.2, P = .89), followed by EuroSCORE II for 30-day mortality (area under curve, 0.87) and SOFA for morbidity (Spearman ρ= 0.37 and 0.35 for the CSICU length of stay and duration of mechanical ventilation, respectively; Wilcoxon W = 367.5, P = .03 for probability of readmission to CSICU). CASUS can be recommended as the most reliable and beneficial option for benchmarking and risk stratification in cardiac surgery patients. ©2015 American Association of Critical-Care Nurses.

    CONCLUSIONS: Cardiac rhabdomyoma are benign from the cardiovascular standpoint in most affected fetuses. An early prenatal diagnosis may help for an adequate planning of perinatal monitoring and treatment with the involvement of a multidisciplinary team. Large tumour size, the number of tumours and localisation may cause hydrops, and they are significantly associated with poor neonatal outcome.

    Objective: To study the maternal and fetal outcome in pregnant and parturient women with cardiac disease admitted in Armed Forces Institute of Cardiology Rawalpindi. Type of Study: Cross sectional descriptive study. Place and Duration: Armed Forces Institute of Cardiology Rawalpindi Jan 2008 to June 2008. Patients and Methods: All pregnant patients beyond 28 weeks gestation with cardiac disease diagnosed before pregnancy or during the index pregnancy admitted for delivery or with cardiac complications were included in the study. All neonates less than 2.5 kg were taken as low birth weight and deliveries between 28 and 37 weeks were considered preterm. Cardiac patients with pregnancy less than 28 weeks were excluded from the study. Results: Maternal mortality was 5% with 31% mortality in NYHA Class III and IV. Perinatal mortality was 9% and low birth weight babies were 17%.Perinatal mortality was 0% in NYHA Class I and II and 60% in NYHA class III and IV. There was no maternal mortality in booked patients. All patients who expired were unbooked. Conclusion: Functional cardiac status is the most important factor affecting maternal and perinatal outcome. Antenatal booking status of the patient is the next important factor. (author)

    Recent studies on comatose survivors of cardiac arrest undergoing targeted temperature management (TTM) have shown similar outcomes at multiple target temperatures. However, details regarding core temperature variability during TTM and its prognostic implications remain largely unknown. We sought to assess the association between core temperature variability and neurological outcomes in patients undergoing TTM following cardiac arrest. We analyzed a prospectively collected cohort of 242 patients treated with TTM following cardiac arrest at a tertiary care hospital between 2007 and 2014. Core temperature variability was defined as the statistical variance (i.e. standard deviation squared) amongst all core temperature recordings during the maintenance phase of TTM. Poor neurological outcome at hospital discharge, defined as a Cerebral Performance Category (CPC) score>2, was the primary outcome. Death prior to hospital discharge was assessed as the secondary outcome. Multivariable logistic regression was used to examine the association between temperature variability and neurological outcome or death at hospital discharge. A poor neurological outcome was observed in 147 (61%) patients and 136 (56%) patients died prior to hospital discharge. In multivariable logistic regression, increased core temperature variability was not associated with increased odds of poor neurological outcomes (OR 0.38, 95% CI 0.11-1.38, p=0.142) or death (OR 0.43, 95% CI 0.12-1.53, p=0.193) at hospital discharge. In this study, individual core temperature variability during TTM was not associated with poor neurological outcomes or death at hospital discharge. Copyright © 2017 Elsevier Inc.

    2017-04-01

    Full Text Available Summary: The degradation and release of cardiac myosin binding protein-C (cMyBP-C upon cardiac damage may stimulate an inflammatory response and autoantibody (AAb production. We determined whether the presence of cMyBP-C-AAbs associated with adverse cardiac function in cardiovascular disease patients. Importantly, cMyBP-C-AAbs were significantly detected in acute coronary syndrome patient sera upon arrival to the emergency department, particularly in ST-segment elevation myocardial infarction patients. Patients positive for cMyBP-C-AAbs had reduced left ventricular ejection fraction and elevated levels of clinical biomarkers of myocardial infarction. We conclude that cMyBP-C-AAbs may serve as early predictive indicators of deteriorating cardiac function and patient outcome in acute coronary syndrome patients prior to the infarction.

    The aim of this study is to examine the predictive value of the Lee revised cardiac risk index (RCRI) for a standard vascular intensive care unit (ICU) population as well as assessing the utility of transthoracic echocardiography and the impact of prior coronary artery disease (CAD) and coronary revascularization on patient outcome. This is a retrospective review of prospectively maintained Vascubase and prospectively collected ICU data. Data from 363 consecutive vascular ICU admissions were collected. Findings were used to calculate the RCRI, which was then correlated with patient outcomes. All patients were on optimal medical therapy (OMT) in the form of cardioselective β-blocker, aspirin, statin, and folic acid. There was no relationship found between a reduced ejection fraction and patient outcome. Mortality was significantly increased for patients with left ventricular hypertrophy (LVH) as identified on echo (14.9% vs 6.5%, P = .028). The overall complication rates were significantly elevated for patients with valvular dysfunction. Discrimination for the RCRI on receiver-operating characteristic analysis was poor, with an area under the receiver-operating characteristic curve of .621. Model calibration was reasonable with an Hosmer-Lemeshow Ĉ statistic of 2.726 (P = .256). Of those with known CAD, 41.22% of the patients receiving best medical treatment developed acute myocardial infarction (AMI) compared to 35.3% of those who previously underwent percutaneous cardiac intervention and 23.5% of those who had undergone coronary artery bypass grafting. There was 3-fold increase in major adverse clinical events in patients with troponin rise and LVH. The RCRI's discriminatory capacity is low, and this raises difficulties in assessing cardiac risk in patients undergoing vascular intervention. The AMI is highest in the OMT group without prior cardiac intervention, which mandates protocols to identify patients requiring cardiac intervention prior to vascular

    Percutaneous coronary intervention (PCI) may be perceived as a frightening experience. Some psychological factors are known correlates of recovery and rehabilitation of cardiac patients. Our objective was to investigate the emotional, cognitive and behavioral effects of patient guidance during their cardiac catheterization. We performed a randomized trial comparing a patient group that was instructed while watching the monitor screen during their PCI (study group) and another group that was not (controls). Replies to questionnaires measuring emotional, cognitive and behavioral variables known to be associated with cardiac patients' health status, rehabilitation and quality of life were collected 1 day and 1 month after the procedure. The study group included 57 patients and the control group included 51 patients. Most patients (∼87%) were men at the mean age of 60. They were well matched for reasons for referral to PCI. The study group reported less pain, a more positive affect, greater self-efficacy and stronger intentions to change health-related behaviors than the control group. At 1 month following the procedure, the study group evaluated their general health as significantly better, and reported a less negative affect, less cardiac anxiety, greater functional self-efficacy and more positive outcome expectancies regarding diet, and quitting smoking than the controls. A simple adjustment in the standard PCI protocol can become a highly beneficial psychological intervention for enhancing patient outcomes.

    Full Text Available Abstract Background Outcome prediction scoring systems are increasingly used in intensive care medicine, but most were not developed for use in cardiac surgery patients. We compared the performance of four intensive care outcome prediction scoring systems (Acute Physiology and Chronic Health Evaluation II [APACHE II], Simplified Acute Physiology Score II [SAPS II], Sequential Organ Failure Assessment [SOFA], and Cardiac Surgery Score [CASUS] in patients after open heart surgery. Methods We prospectively included all consecutive adult patients who underwent open heart surgery and were admitted to the intensive care unit (ICU between January 1st 2007 and December 31st 2008. Scores were calculated daily from ICU admission until discharge. The outcome measure was ICU mortality. The performance of the four scores was assessed by calibration and discrimination statistics. Derived variables (Mean- and Max- scores were also evaluated. Results During the study period, 2801 patients (29.6% female were included. Mean age was 66.9 ± 10.7 years and the ICU mortality rate was 5.2%. Calibration tests for SOFA and CASUS were reliable throughout (p-value not Conclusions CASUS and SOFA are reliable ICU mortality risk stratification models for cardiac surgery patients. SAPS II and APACHE II did not perform well in terms of calibration and discrimination statistics.

    Unexplained syncope is a challenge facing electrophysiologists. The prognosis varies widely depending on underlying causes, specially, cardiac ones. We sought to determine the abnormal electrophysiolgic (EP) study results as predictors of prognosis in syncope patients with suspected cardiac cause and risk factors associated with mortality. A total of 227 consecutive patients with unexplained syncope were prospectively enrolled in this study. EP study was performed in 177 patients in base of inclusion criteria. These patients, in whom a cardiac cause of syncope was suspected, underwent EP study and if negative, head-up tilts test (HUTT). Complete follow-up was obtained for 132 patients for 20.0±10.8 months. A cardiac cause of syncope was established in 35%, a neurally mediated syncope in 35.6%, and in the rest 29.4% the cause of syncope remained unexplained despite a throughout neurologic and cardiologic evaluation. Logistic analysis revealed that the significant predictors of a cardiac cause of syncope were the absence of prodromal symptoms, left bundle branch block (LBBB), sever left ventricle (LV) dysfunction and male gender. At logistic analysis, the presence of LBBB (OR=6.63; 95% CI: 1.09-40) was significantly associated with outcome of death. The present study provides evidence that presence of LBBB, abnormal EP study result and structural heart disease (SHD) have prognostic value in patients with suspected cardiac cause of syncope. The patients with SHD and unexplained syncope who had a negative EP study have a good long-term prognosis even in the presence of LV dysfunction.

    Background High levels of serum uric acid have been associated with adverse outcomes in cardiovascular diseases such as myocardial infarction and heart failure. The aim of the current study was to evaluate the prognostic role of serum uric acid levels in patients undergoing cardiac rehabilitation after myocardial revascularization and/or cardiac valve surgery. Design We performed an observational prospective cohort study. Methods The study included 1440 patients with available serum uric acid levels, prospectively followed for 50 ± 17 months. Mean age was 67 ± 11 years; 781 patients (54%) underwent myocardial revascularization, 474 (33%) cardiac valve surgery and 185 (13%) valve-plus-coronary artery by-pass graft surgery. The primary endpoints were overall and cardiovascular mortality while secondary end-points were combined major adverse cardiac and cerebrovascular events. Results Serum uric acid level mean values were 286 ± 95 µmol/l and elevated serum uric acid levels (≥360 µmol/l or 6 mg/dl) were found in 275 patients (19%). Overall mortality (hazard ratio = 2.1; 95% confidence interval: 1.5-3.0; p uric acid levels, even after adjustment for age, gender, arterial hypertension, diabetes, glomerular filtration rate, atrial fibrillation and medical therapy. Moreover, strong positive correlations between serum uric acid level and probability of overall mortality ( p uric acid levels predict mortality and adverse cardiovascular outcome in patients undergoing myocardial revascularization and/or cardiac valve surgery even after the adjustment for age, gender, arterial hypertension, diabetes, glomerular filtration rate and medical therapy.

    Cerebral edema is one physical change associated with brain injury and decreased survival after cardiac arrest. Edema appears on computed tomography (CT) scan of the brain as decreased X-ray attenuation by gray matter. This study tested whether the gray matter attenuation to white matter attenuation ratio (GWR) was associated with survival and functional recovery. Subjects were patients hospitalized after cardiac arrest at a single institution between 1/1/2005 and 7/30/2010. Subjects were included if they had non-traumatic cardiac arrest and a non-contrast CT scan within 24h after cardiac arrest. Attenuation (Hounsfield Units) was measured in gray matter (caudate nucleus, putamen, thalamus, and cortex) and in white matter (internal capsule, corpus callosum and centrum semiovale). The GWR was calculated for basal ganglia and cerebrum. Outcomes included survival and functional status at hospital discharge. For 680 patients, 258 CT scans were available, but 18 were excluded because of hemorrhage (10), intravenous contrast (3) or technical artifact (5), leaving 240 CT scans for analysis. Lower GWR values were associated with lower initial Glasgow Coma Scale motor score. Overall survival was 36%, but decreased with decreasing GWR. The average of basal ganglia and cerebrum GWR provided the best discrimination. Only 2/58 subjects with average GWR<1.20 survived and both were treated with hypothermia. The association of GWR with functional outcome was completely explained by mortality when GWR<1.20. Subjects with severe cerebral edema, defined by GWR<1.20, have very low survival with conventional care, including hypothermia. GWR estimates pre-treatment likelihood of survival after cardiac arrest. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Illness severity scores are commonly employed in critically ill patients to predict outcome. To date, prior scores for post-cardiac arrest patients rely on some event-related data. We developed an early, novel post-arrest illness severity score to predict survival, good outcome and development of multiple organ failure (MOF) after cardiac arrest. Retrospective review of data from adults treated after in-hospital or out-of-hospital cardiac arrest in a single tertiary care facility between 1/1/2005 and 12/31/2009. In addition to clinical data, initial illness severity was measured using serial organ function assessment (SOFA) scores and full outline of unresponsiveness (FOUR) scores at hospital or intensive care unit arrival. Outcomes were hospital mortality, good outcome (discharge to home or rehabilitation) and development of multiple organ failure (MOF). Single-variable logistic regression followed by Chi-squared automatic interaction detector (CHAID) was used to determine predictors of outcome. Stepwise multivariate logistic regression was used to determine the independent association between predictors and each outcome. The Hosmer-Lemeshow test was used to evaluate goodness of fit. The n-fold method was used to cross-validate each CHAID analysis and the difference between the misclassification risk estimates was used to determine model fit. Complete data from 457/495 (92%) subjects identified distinct categories of illness severity using combined FOUR motor and brainstem subscales, and combined SOFA cardiovascular and respiratory subscales: I. Awake; II. Moderate coma without cardiorespiratory failure; III. Moderate coma with cardiorespiratory failure; and IV. Severe coma. Survival was independently associated with category (I: OR 58.65; 95% CI 27.78, 123.82; II: OR 14.60; 95% CI 7.34, 29.02; III: OR 10.58; 95% CI 4.86, 23.00). Category was also similarly associated with good outcome and development of MOF. The proportion of subjects in each category changed

    Emergency department (ED) overcrowding is a worldwide problem associated with adverse outcomes. This study was performed to investigate the association between ED overcrowding and the outcomes and quality of cardiopulmonary resuscitation for out-of-hospital cardiac arrest (OHCA). Prospectively collected data including patients' demographics, Utstein factors, and outcomes on 608 consecutive OHCA patients at a single ED from January 2008 to December 2012 were retrospectively analyzed. The patients were categorized into 4 groups according to ED occupancy rate. The primary outcome was resuscitation outcome, a composite of rates of return of spontaneous circulation (ROSC), survival at discharge, and neurologic outcome at 6months. The secondary outcome was resuscitation quality assessed by time to advanced airway, time to first drug administration, resuscitation duration in refractory cases, and rate of initiation of therapeutic hypothermia after ROSC in the ED. There was no significant difference in rates of ROSC, survival at discharge, and good neurologic outcome according to ED occupancy rate in the univariate and multivariate analyses (P>.05). In addition, ED overcrowding was not associated with resuscitation quality (P>.05). Emergency department overcrowding was not associated with the outcomes of OHCA or resuscitation quality.

    The degradation and release of cardiac myosin binding protein-C (cMyBP-C) upon cardiac damage may stimulate an inflammatory response and autoantibody (AAb) production. We determined whether the presence of cMyBP-C-AAbs associated with adverse cardiac function in CVD patients. Importantly, cMyBP-C-AAbs were significantly detected in ACS patient sera upon arrival to the emergency department, particularly in STEMI patients. Patients positive for cMyBP-C-AAbs had a reduced LVEF and elevated levels of clinical biomarkers of MI. We conclude that cMyBP-C-AAbs may serve as early predictive indicators of deteriorating cardiac function and patient outcome in ACS patients prior to the infarction.

    To assess how obesity or diabetes mellitus impacts outcomes in patients undergoing cardiac surgery in pediatric hospitals. A multi-institutional, matched case-control study of the Pediatric Health Information System database was performed. Tertiary children's hospitals in the United States. All cardiac surgical cases in patients with obesity or diabetes mellitus between 2004 and 2012 were included. Cases were matched to controls by age, sex, race, and Risk Adjustment for Congenital Heart Surgery score. Mortality, surgical complications, and hospital utilization. Differences in outcome measures were assessed by chi-square and Mann-Whitney tests. P value obesity or diabetes mellitus were matched to 629 controls. Cases demonstrated lower median household income than those in the control group ($38,031 [IQR $31,900-$48,844] vs. ($41,896 [IQR $32,854-$56,020], P 96 hours (OR 2.0, 95% CI 1.1-3.7) and higher rate of total parenteral nutrition use (7.2% vs. 4.5%, P = .040). Median hospital charges were higher in cases (clinical: $6,696 vs. $5,872; laboratory: $14,168 vs. $12,251; pharmacy: $12,971 vs. $10,426; imaging: $6,259 vs. $5,660; P ≤ .030 for all). The presence of obesity or diabetes mellitus was associated with increased postoperative morbidity, hospital utilization, and cost in patients undergoing cardiac surgery in pediatric hospitals. © 2016 Wiley Periodicals, Inc.

    Although the number of pregnancies in women with cardiac disease is increasing worldwide, there are few data concerning their clinical characteristics and peripartum outcomes. Using the Diagnosis Procedure Combination database between 2008 and 2014 in Japan, we retrospectively identified pregnant women who underwent high-risk delivery due to obstetric or non-obstetric comorbidities. We classified eligible women into those with pre-existing cardiac disease (cardiac disease group) and those with non-cardiac comorbidities (non-cardiac disease group) and compared their characteristics and peripartum outcomes. Of 94,364 women undergoing high-risk delivery at 556 hospitals, 857 (0.91%) had pre-existing cardiac disease (302, congenital heart disease; 190, arrhythmia; 176, valvular heart disease; 120, ischemic heart disease; 65, cardiomyopathy; 4, pericardial disease). Women in the cardiac disease group were more likely to be treated at university hospitals (51.1 versus 28.6%; p women with congenital heart disease (12.3%), valvular heart disease (12.5%), or cardiomyopathy (12.3%) than in women with arrhythmia (6.3%) or ischemic heart disease (5.8%). Multivariable logistic regression analysis showed a significant positive association between pre-existing cardiac disease and risk of heart failure (adjusted odds ratio, 24.7; 95% confidence interval, 17.6-34.6; p woman in the cardiac disease group died, whereas 18 women (0.02%) in the non-cardiac disease group did (p = 1.000). These findings suggest that pregnant women with pre-existing cardiac disease are at a higher risk of heart failure during the peripartum period than those with non-cardiac comorbidities.

    The effect of bystander interventions on long-term functional outcomes among survivors of out-of-hospital cardiac arrest has not been extensively studied. We linked nationwide data on out-of-hospital cardiac arrests in Denmark to functional outcome data and reported the 1-year risks of anoxic brain damage or nursing home admission and of death from any cause among patients who survived to day 30 after an out-of-hospital cardiac arrest. We analyzed risks according to whether bystander cardiopulmonary resuscitation (CPR) or defibrillation was performed and evaluated temporal changes in bystander interventions and outcomes. Among the 2855 patients who were 30-day survivors of an out-of-hospital cardiac arrest during the period from 2001 through 2012, a total of 10.5% had brain damage or were admitted to a nursing home and 9.7% died during the 1-year follow-up period. During the study period, among the 2084 patients who had cardiac arrests that were not witnessed by emergency medical services (EMS) personnel, the rate of bystander CPR increased from 66.7% to 80.6% (Pthe rate of bystander defibrillation increased from 2.1% to 16.8% (Pthe rate of brain damage or nursing home admission decreased from 10.0% to 7.6% (Pbystander CPR was associated with a risk of brain damage or nursing home admission that was significantly lower than that associated with no bystander resuscitation (hazard ratio, 0.62; 95% confidence interval [CI], 0.47 to 0.82), as well as a lower risk of death from any cause (hazard ratio, 0.70; 95% CI, 0.50 to 0.99) and a lower risk of the composite end point of brain damage, nursing home admission, or death (hazard ratio, 0.67; 95% CI, 0.53 to 0.84). The risks of these outcomes were even lower among patients who received bystander defibrillation as compared with no bystander resuscitation. In our study, we found that bystander CPR and defibrillation were associated with risks of brain damage or nursing home admission and of death from any cause that were

    Most out-of-hospital cardiac arrests receiving emergency medical services in the United States are treated by ambulance service providers trained in advanced life support (ALS), but supporting evidence for the use of ALS over basic life support (BLS) is limited. To compare the effects of BLS and ALS on outcomes after out-of-hospital cardiac arrest. Observational cohort study of a nationally representative sample of traditional Medicare beneficiaries from nonrural counties who experienced out-of-hospital cardiac arrest between January 1, 2009, and October 2, 2011, and for whom ALS or BLS ambulance services were billed to Medicare (31,292 ALS cases and 1643 BLS cases). Propensity score methods were used to compare the effects of ALS and BLS on patient survival, neurological performance, and medical spending after cardiac arrest. Survival to hospital discharge, to 30 days, and to 90 days; neurological performance; and incremental medical spending per additional survivor to 1 year. Survival to hospital discharge was greater among patients receiving BLS (13.1% vs 9.2% for ALS; 4.0 [95% CI, 2.3-5.7] percentage point difference), as was survival to 90 days (8.0% vs 5.4% for ALS; 2.6 [95% CI, 1.2-4.0] percentage point difference). Basic life support was associated with better neurological functioning among hospitalized patients (21.8% vs 44.8% with poor neurological functioning for ALS; 23.0 [95% CI, 18.6-27.4] percentage point difference). Incremental medical spending per additional survivor to 1 year for BLS relative to ALS was $154,333. Patients with out-of-hospital cardiac arrest who received BLS had higher survival at hospital discharge and at 90 days compared with those who received ALS and were less likely to experience poor neurological functioning.

    Outcome prediction scoring systems are increasingly used in intensive care medicine, but most were not developed for use in cardiac surgery patients. We compared the performance of four intensive care outcome prediction scoring systems (Acute Physiology and Chronic Health Evaluation II [APACHE II], Simplified Acute Physiology Score II [SAPS II], Sequential Organ Failure Assessment [SOFA], and Cardiac Surgery Score [CASUS]) in patients after open heart surgery. We prospectively included all consecutive adult patients who underwent open heart surgery and were admitted to the intensive care unit (ICU) between January 1st 2007 and December 31st 2008. Scores were calculated daily from ICU admission until discharge. The outcome measure was ICU mortality. The performance of the four scores was assessed by calibration and discrimination statistics. Derived variables (Mean- and Max- scores) were also evaluated. During the study period, 2801 patients (29.6% female) were included. Mean age was 66.9 ± 10.7 years and the ICU mortality rate was 5.2%. Calibration tests for SOFA and CASUS were reliable throughout (p-value not predicted and observed outcome for SAPS II (days 1, 2, 3 and 5) and APACHE II (days 2 and 3). CASUS, and its mean- and maximum-derivatives, discriminated better between survivors and non-survivors than the other scores throughout the study (area under curve ≥ 0.90). In order of best discrimination, CASUS was followed by SOFA, then SAPS II, and finally APACHE II. SAPS II and APACHE II derivatives had discrimination results that were superior to those of the SOFA derivatives. CASUS and SOFA are reliable ICU mortality risk stratification models for cardiac surgery patients. SAPS II and APACHE II did not perform well in terms of calibration and discrimination statistics.

    The administration of aprotinin to patients with pre-existing renal dysfunction who are undergoing cardiac surgery is controversial. Therefore, the authors present their experience with the use of aprotinin for patients with preoperative renal dysfunction who underwent elective cardiac surgery requiring cardiopulmonary bypass (CPB). Retrospective analysis. University hospital. Consecutive cardiac surgical patients with preoperative serum creatinine (SCr) > or =1.8 mg/dL undergoing nonemergent cardiac surgery requiring CPB. None. One hundred twenty-three patients either received epsilon aminocaproic acid (EACA, n = 82) or aprotinin (n = 41) as decided by the attending anesthesiologist and surgeon. Data were collected from the Society of Thoracic Surgeons database and from automated intraoperative anesthesia records. Renal function was assessed from measured serum creatinine (SCr) and calculated creatinine clearances (CrCls). Acute perioperative renal dysfunction was defined as a worsening of perioperative renal function by > or =25% and/or the need for hemodialysis (HD). Data were recorded as mean and standard deviation or percentage of population depending on whether the data were continuous or not. Data were compared by using an analysis of variance, chi-square analysis, Student paired and unpaired t tests, Fisher exact test, Wilcoxon rank sum test, and Mann-Whitney U test. A p value or =3 months after surgery was significantly lower in the aprotinin group compared with the EACA group (1.8 v 2.2 mg/dL, p < 0.05). Acute perioperative renal dysfunction was associated with worse patient outcome and longer CPB and AoXCl times. Demographic and surgical variables indicated that the sicker patients undergoing more complex surgeries were more likely to be treated with aprotinin. Although aprotinin patients had a higher renal risk score, the administration of aprotinin did not negatively impact renal outcome.

    To examine the impact of population density on incidence and outcome of out-of-hospital cardiac arrest (OHCA). Data were extracted from the Victorian Ambulance Cardiac Arrest Registry for all adult OHCA cases of presumed cardiac aetiology attended by the emergency medical service (EMS) between 1 January 2003 and 31 December 2011. Cases were allocated into one of five population density groups according to their statistical local area: very low density (≤ 10 people/km(2)), low density (11-200 people/km(2)), medium density (201-1000 people/km(2)), high density (1001-3000 people/km(2)), and very high density (> 3000 people/km(2)). Survival to hospital and survival to hospital discharge. The EMS attended 27 705 adult presumed cardiac OHCA cases across 204 Victorian regions. In 12 007 of these (43.3%), resuscitation was attempted by the EMS. Incidence was lower and arrest characteristics were consistently less favourable for lower population density groups. Survival outcomes, including return of spontaneous circulation, survival to hospital and survival to hospital discharge, were significantly poorer in less densely populated groups (P populations, the risk-adjusted odds ratios of surviving to hospital discharge were: low density, 1.88 (95% CI, 1.15-3.07); medium density, 2.49 (95% CI, 1.55-4.02); high density, 3.47 (95% CI, 2.20-5.48) and very high density, 4.32 (95% CI, 2.67-6.99). Population density is independently associated with survival after OHCA, and significant variation in the incidence and characteristics of these events are observed across the state.

    Telemedical assistance has always been the cornerstone of medical care on board. Significant technological progress has provided improved scientific tools and equipment for high-quality communication and prompt management of either minor incidents or major emergencies on board. Med Solutions International is a medical management company, offering services exclusively to the maritime industry. Registered vessels contact the medical team and healthcare professionals provide immediate guidelines for onboard management as well as necessary action thereafter, i.e. examination ashore or urgent medical evacuation. Since cardiac conditions or diseases are potentially the most dangerous when traveling at sea, it is of major importance to analyse and evaluate the overall management and outcomes of cases reporting symptoms of possible heart disease so as to improve telemedical assistance services in future. The study included cases reporting cardiac symptoms from 5 major shipping companies during the year 2016. Data was collected from telecommunication, emails and seafarers' final medical reports. A descriptive analysis of overall management and outcomes was performed. The study showed that the number of confirmed cardiovascular cases on board was very low. Among 551 total cases and 44 cases with reported cardiac symptoms there was only one heart attack, one pulmonary oedema and one suspected myocarditis. In the majority of cases, chest pain was musculoskeletal or due to respiratory infection. Symptoms resulting from issues such as stress or anxiety often present as potential cardiac conditions. Stress may also amplify the severity of symptoms. Language barriers between the seafarer, the master and the doctor often make communication very difficult. According to our findings there are grounds to intensify the prevention process through more efficient pre-employment medical examinations and improve management on board through more intensive training.

    Spontaneous alterations in temperature homeostasis after cardiac arrest (CA) are associated with worse outcome. However, it remains unclear the prognostic role of temperature variability (TV) during cooling procedures. We hypothesized that low TV during targeted temperature management (TTM) would be associated with a favourable neurological outcome after CA. We reviewed data from all comatose patients after in-hospital or out-of-hospital CA admitted to our Department of Intensive Care between December 2006 and January 2014 who underwent TTM (32-34°C) and survived at least 24h. We collected demographic data, CA characteristics, intensive care unit (ICU) survival and neurological outcome at three months (favourable neurological outcome was defined as cerebral performance category 1-2). TV was expressed using the standard deviation (SD) of all temperature measurements during hypothermia; high TV was defined as an SD >1°C. Of the 301 patients admitted over the study period, 72 patients were excluded and a total of 229 patients were studied; 88 had a favourable neurological outcome. The median temperature on ICU admission was 35.8 [34.9-36.9]°C and the median time to hypothermia (body temperature temperature were independent predictors of favourable neurological outcome, but TV was not. Among comatose survivors treated with TTM after CA, 25% of patients had high TV; however, this was not associated with a worse neurologic outcome. Copyright © 2015 Elsevier Ireland Ltd.

    Prior investigation has found that mechanical ventilation with lower tidal volumes (Vt) following out-of-hospital cardiac arrest is associated with better neurologic outcomes. The relationship between Vt and neurologic outcome following in-hospital cardiac arrest (IHCA) has not previously been explored. In the present study, we investigate the association between Vt and neurologic outcome following IHCA. This was an observational study using a prospectively collected database of IHCA patients at a tertiary care hospital in the United States. The relationship between time-weighted average Vt per predicted body weight (PBW) over the first 6- and 48 h after cardiac arrest and neurologic outcome were assessed using propensity-score adjusted logistic regression. Of 185 IHCA patients who received invasive mechanical ventilation within 6 h of return of spontaneous circulation (ROSC), the average Vt over the first 6 h was 7.7 ± 2.0 ml/kg and 68 (36.8%) patients received an average Vt > 8.0 ml/kg. Of 121 patients who received mechanical ventilation for at least 48 h post-ROSC, the average Vt was 7.6 ± 1.5 ml/kg and 46 (38.0%) patients received an average Vt > 8.0 ml/kg. There was no relationship between Vt/PBW over the first 6- or 48 h post-ROSC and neurologic outcome (OR 0.99; 95%CI 0.84-1.16; p = 0.89; OR 1.03; 95%CI 0.78-1.37; p = 0.83 respectively). This study did not identify a relationship between Vt and neurologic outcome following IHCA. This contrasts with results in OHCA, where higher Vt has been associated with worse neurologic outcome. Additional investigation is needed with respect to other potential benefits of low-Vt post IHCA. Copyright © 2018 Elsevier B.V. All rights reserved.

    To determine the reliability (internal consistency, inter-rater reproducibility and level of agreement) of nursing outcome: "Knowledge: cardiac disease management (1830)" of the version published in Spanish, in outpatients with heart failure. A reliability study was conducted on 116 outpatients with heart failure. Six indicators of nursing outcome were operationalized. All participants were assessed simultaneously by two evaluators. Three evaluation periods were defined: initial (at baseline), final (a month later), and follow-up (two months later). Internal consistency by Cronbach alpha coefficient, inter-rater reproducibility with intraclass correlation coefficient of reproducibility or agreement and level agreement using the 95% limits of Bland and Altman. Cronbach's alpha was 0.83 (95% CI: 0.77 - 0.89) in the final evaluation, and follow-up values of 0.85 (95% CI: 0.82-0.89) and 0.83 (95% CI: 0.78 - 0.88) were found for the first and second evaluator, respectively. The intraclass correlation coefficient showed values greater 0.9 in the three evaluation periods in both the random and mixed model. The Bland-Altman 95% limits of agreement were close to zero in the three evaluations performed. The questionnaire operationalized to assess the nursing outcome: "Knowledge: cardiac disease management (1830)" in its Spanish version, is a reliable method to measure skills and knowledge in outpatients with heart failure in the Colombian context.

    To examine gender differences among cardiac arrest (CA) survivors' cognitive, functional, and psychiatric outcomes at discharge. This is a prospective, observational cohort of 187 CA patients admitted to Columbia University Medical Center, considered for Targeted Temperature Management (TTM), and survived to hospital discharge between September 2015 and July 2017. Patients with sufficient mental status at hospital discharge to engage in the Repeatable Battery for Neuropsychological Status (RBANS), Modified Lawton Physical Self-Maintenance Scale (M-PSMS), Cerebral Performance Category Scale (CPC), Center for Epidemiological Studies Depression Scale (CES-D), and Post-Traumatic Stress Disorder Checklist - Civilian Version (PCL-C) were included. Fisher's exact, Wilcoxon Rank Sum, and regression analysis were utilized. 80 patients (38% women, 44% white, mean age 53 ± 17 years) were included. No significant gender differences were found for age, race, Charlson Comorbidity Index, premorbid CPC or psychiatric diagnoses, arrest related variables, discharge CPC, or PCL-C scores. Women had significantly worse RBANS (64.9 vs 74.8, p = .01), M-PSMS (13.6 vs 10.6, p = .02), and CES-D (22.8 vs 14.3, p = .02) scores. These significant differences were maintained in multivariate models after adjusting for age, initial rhythm, time to return of spontaneous circulation, and TTM. Women have worse cognitive, functional, and psychiatric outcomes at hospital discharge after cardiac arrest than men. Identifying factors contributing to these differences is of great importance in cardiac arrest outcomes research. Copyright © 2018 Elsevier B.V. All rights reserved.

    Telemetry is increasingly used to monitor hospitalized patients with lower intensities of care, but its effect on in-hospital cardiac arrest (IHCA) outcomes in non-critical care patients is unknown. Telemetry utilization in non-critical care patients does not affect IHCA outcomes. A retrospective cohort analysis of all patients in non-critical care beds that experienced a cardiac arrest in a university-affiliated teaching hospital during calendar years 2011 and 2012 was performed. Data were collected as part of AHA Get With the Guidelines protocol. The independent variable and exposure studied were whether patients were on telemetry or not. Telemetry was monitored from a central location. The primary endpoint was return of spontaneous circulation (ROSC) and the secondary end point was survival to discharge. Of 123 IHCA patients, the mean age was 75±15 and 74 (61%) were male. 80 (65%) patients were on telemetry. Baseline demographics were similar except for age; patients on telemetry were younger with mean age of 70.3 vs. 76.8 in the non-telemetry group (p=0.024). 72 patients (60%) achieved ROSC and 46 (37%) achieved survival to discharge. By univariate analysis, there was no difference between patients that had been on telemetry vs. no telemetry in ROSC (OR=1.13, p=0.76) or survival to discharge (OR=1.18, p=0.67). Similar findings were obtained with multivariate analysis for ROSC (0.91, p=0.85) and survival to discharge (OR=0.92, p=0.87). The use of cardiac telemetry in non-critical care beds, when monitored remotely in a central location, is not associated with improved IHCA outcomes. Copyright © 2015 Elsevier Inc.

    There is paucity of data examining the incidence and outcomes of young OHCA adults. The aim of this study is to determine the outcomes and characteristics of young adults who suffered an OHCA and identify factors that are associated with favourable neurologic outcomes. All EMS-attended OHCA adults between the ages of 16 and 35 years in the Pan-Asian Resuscitation Outcomes Study (PAROS) registry were analysed. The primary outcome was favourable neurologic outcome (Cerebral Performance Category 1 or 2) at hospital discharge or at 30th day post OHCA if not discharged. Regression analysis was performed to identify factors associated with favourable neurologic outcomes. 66,780 OHCAs were collected between January 2009 and December 2013; 3244 young OHCAs had resuscitation attempted by emergency medical services (EMS). 56.8% of patients had unwitnessed arrest; 47.9% were of traumatic etiology. 17.2% of patients (95% CI: 15.9-18.5%) had return of spontaneous circulation; 7.8% (95% CI: 6.9-8.8%) survived to one month; 4.6% (95% CI: 4.0-5.4%) survived with favourable neurologic outcomes. Factors associated with favourable neurologic outcomes include witnessed arrest (adjusted RR=2.42, p-valueyoung adults are not uncommon. Traumatic OHCA, occurring most frequently in young adults had dismal prognosis. First arrest rhythms of VF/VT/unknown shockable rhythm, cardiac etiology, bystander-witnessed arrest, and bystander CPR were associated with favourable neurological outcomes. The results of the study would be useful for planning preventive and interventional strategies, improving EMS, and guiding future research. Copyright © 2016 Elsevier Ireland Ltd.

    To assess whether introduction of universal leukodepletion (ULD) of red blood cells (RBCs) for transfusion was associated with improvements in cardiac surgery patient outcomes. Retrospective study (2005-2010) conducted at 6 institutions. Associations between leukodepletion and outcomes of mortality, infection, and acute kidney injury (AKI) were modeled by logistic regression, and intensive care unit length of stay (LOS) in survivors was explored using linear regression. To examine trends over time, odds ratios (ORs) for outcomes of transfused were compared with nontransfused patients, including a comparison with nontransfused patients who were selected based on propensity score for RBC transfusion. We studied 14,980 patients, of whom 8857 (59%) had surgery pre-ULD. Transfusions of RBCs were made in 3799 (43%) pre-ULD, and 2525 (41%) post-ULD. Administration of exclusively leukodepleted, versus exclusively nonleukodepleted, RBCs was associated with lower incidence of AKI (adjusted OR 0.80, 95% confidence interval [CI] 0.65-0.98, P = .035), but no difference in mortality or infection. For post-ULD patients, no difference was found in mortality (OR 0.96, 95% CI 0.76-1.22, P = .76) or infection (OR 0.91, 95% CI 0.79-1.03, P = .161); however, AKI was reduced (OR 0.79 95% CI 0.68-0.92, P = .003). However, ORs for post-ULD outcomes were not significantly different in nontransfused, versus transfused, patients. Furthermore, those who received exclusively nonleukodepleted RBCs were more likely to have surgery post-ULD. Universal leukodepletion was not associated with reduced mortality or infection in transfused cardiac surgery patients. An association was found between ULD and reduced AKI; however, this reduction was not significantly different from that seen in nontransfused patients, and other changes in care most likely explain such changes in renal outcomes.

    Objective We aimed to present clinical features, surgical approaches, importance of surgical technique and long-term outcomes of our patients with cardiac myxoma who underwent surgery. Methods We retrospectively collected data of patients with cardiac myxoma who underwent surgical resection between February 1990 and November 2014. Biatrial approach is the preferred surgical method in a large proportion of patients that are operated due to left atrial myxoma because it provides wider exposure than the uniatrial approach. To prevent recurrence during surgical resection, a large excision is made so as to include at least 5 mm of normal area from clean tissue around the tumor. Moreover, special attention is paid to the excision that is made as a whole, without digesting the fragment of tumor with gentle dissections. Results Forty-three patients (20 males, mean age of 51.7±8.8 years) were included. Most common symptom was dyspnea (48.8%). Tumor was located in the left atrium in 37 (86%) patients. Resections were achieved via biatrial approach in 34 patients, uniatrial approach in 8 patients, and right atriotomy with right ventriculotomy in 1 patient. One patient died due to low cardiac output syndrome in the early postoperative period. Mean follow-up time was 102.3±66.5 months. Actuarial survival rates were 95%, 92% and 78% at five, 10 and 15 years, respectively. Recurrence was observed in none of the patients during follow-up. Conclusion Although myxomas are benign tumors, due to embolic complications and obstructive signs, they should be treated surgically as soon as possible after diagnosis. To prevent recurrence, especially in cardiac myxomas which are located in left atrium, preferred biatrial approach is suggested for wide resection of the tumor and to avoid residual tumor.

    Full Text Available Abstract Background Veno-arterial extracorporeal membrane oxygenation (ECMO is a common modality of circulatory assist device used in children. We assessed the outcome of children who had ECMO following repair of congenital cardiac defects (CCD and identified the risk factors associated with hospital mortality. Methods From April 1990 to December 2003, 53 patients required ECMO following surgical correction of CCD. Retrospectively collected data was analyzed with univariate and multivariate logistic regression analysis. Results Median age and weight of the patients were 150 days and 5.4 kgs respectively. The indications for ECMO were low cardiac output in 16, failure to wean cardiopulmonary bypass in 13, cardiac arrest in 10 and cardio-respiratory failure in 14 patients. The mean duration of ECMO was 143 hours. Weaning off from ECMO was successful in 66% and of these 83% were survival to hospital-discharge. 37.7% of patients were alive for the mean follow-up period of 75 months. On univariate analysis, arrhythmias, ECMO duration >168 hours, bleeding complications, renal replacement therapy on ECMO, arrhythmias and cardiac arrest after ECMO were associated with hospital mortality. On multivariate analysis, abnormal neurology, bleeding complications and arrhythmias after ECMO were associated with hospital mortality. Extra and intra-thoracic cannulations were used in 79% and 21% of patients respectively and extra-thoracic cannulation had significantly less bleeding complications (p = 0.031. Conclusion ECMO provides an effective circulatory support following surgical repair of CCD in children. Extra-thoracic cannulation is associated with less bleeding complications. Abnormal neurology, bleeding complications on ECMO and arrhythmias after ECMO are poor prognostic indicators for hospital survival.

    A low level of serum albumin is common in chronic kidney disease (CKD) patients with heart failure (HF). Cardiac resynchronization therapy (CRT), a novel therapeutic option, improves cardiac performance in patients with severe HF. In addition, CKD has recently been found to be associated with outcomes after CRT; however, the associations of the serum albumin levels with adverse events and the long-term prognosis in CKD patients who have undergone CRT are unknown. In this study, we investigated whether the albumin levels can be used to the predict mortality rate and incidence of cardiovascular events in CKD patients treated with CRT. A retrospective chart review was conducted in 102 consecutive CKD patients receiving a CRT device for the treatment of advanced HF. The long-term outcomes following device implantation were assessed according to the albumin levels. During a median follow-up of 2.6 years, 34 patients (33.3%) died and 66 patients (64.7%) experienced cardiovascular events. A Kaplan-Meier survival analysis revealed that the CKD patients with decreased albumin levels exhibited significantly higher rates of all-cause mortality and cardiovascular events, including hospitalization for progressive HF, than the CKD patients without hypoalbuminemia. Importantly, a multivariate Cox regression analysis of confounding factors showed a low serum albumin level to independently predict all-cause death and cardiovascular events. Hypoalbuminemia independently predicts cardiac morbidity and mortality in CKD patients receiving CRT. Assessing the albumin levels provides valuable information regarding the long-term prognosis in CKD patients who undergo CRT.

    To assess factors associated with survival of out-of-hospital cardiac arrest (OHCA) in patients who underwent cardiopulmonary resuscitation (CPR) during ambulance transport. Retrospective analysis of a registry of OHCA cases treated between 2008 and 2014. We included patients who had not recovered circulation at the time it was decided to transport to a hospital and who were rejected as non-heart-beating donors. Multivariate analysis was used to explore factors associated with the use of ambulance CPR, survival, and neurologic outcome. Out of a total of 7241 cases, 259 (3.6%) were given CPR during emergency transport. The mean (SD) age was 51.6 (23.6) years; 27 (10.1%) were aged 16 years or younger. The following variables were associated with the use of CPR during transport: age 16 years or under (odds ratio [OR], 6.48; 95% CI, 3.91-10.76); P<.001)], witnessed OHCA (OR, 1.62; 95% CI, 1.16-2.26; P=.004), cardiac arrest outside the home (OR, 3.17; 95% CI, 2.38-4.21; P<.001), noncardiac cause (OR, 1.47; 95% CI, 1.07-2.02; P=.019], initially shockable rhythm (OR, 1.67; 95% CI, 1.17-2.37; P=.004), no prior basic life support (OR, 3.48; 95% CI, 2.58-4.70; P<.001), and orotracheal intubation (OR, 1.93; 95% CI, 1.24-2.99; P=.003). One patient (0.38%) survived to discharge with good neurologic outcome. Ambulance CPR by a physician on board is applied in few OHCA cases. Young patient age, cardiac arrest outside the home, the presence of a witness, lack of a shockable rhythm on responder arrival, lack of basic life support prior to responder arrival, noncardiac cause, and orotracheal intubation are associated with the use of ambulance CPR, a strategy that can be considered futile.

    We aimed to describe and compare the epidemiologic features and outcomes among patients with poisoning-induced out-of-hospital cardiac arrests (POHCAs) according to causative agent groups. We identified emergency medical service (EMS)-treated POHCA patients from a nationwide OHCA registry between 2006 and 2008, which was derived from EMS run sheets and followed by hospital record review. Utstein elements were collected and hospital outcomes (survival to admission and to discharge) were measured. We compared risk factors and outcomes according to the main poisons. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated from a multivariate logistic regression model for hospital outcomes. The total number of non-cardiac aetiology OHCAs was 20,536. Of these, the number of EMS-assessed and EMS-treated POHCAs was 900 (4.4%). For EMS-treated POHCAs, insecticides (n=111, 15.5%) including organophosphate and carbamates; herbicides (n=94, 13.2%); unknown pesticides (n=142, 19.9%); non-pesticide drugs (n=120, 16.8%); and unknown poisons (n=247, 6%) were identified. The survival to admission rate was 22.5% for insecticides, 3.2% for herbicides, 16.2% for unknown pesticides, 16.7% for non-pesticides and 11.3% for the unknown group. The survival to discharge rates were 9.9% for insecticides, 0.0% for herbicides, 2.1% for unknown pesticides, 3.3% for non-pesticides and 3.2% for the unknown group. The adjusted OR for each group for survival to admission was significantly lower when compared with insecticides: herbicides (OR=0.11, 95% CI=0.03-0.44), non-pesticide drugs (OR=0.28, 95% CI=0.13-0.61) and unknown group (OR=0.40, 95% CI=0.21-0.76). The adjusted OR for each group for survival to discharge was significantly lower when compared with insecticides: herbicides (OR99.9), unknown pesticides (OR=0.23, 95% CI=0.0.06-0.87), non-pesticide drugs (OR=0.14, 95% CI=0.04-0.54) and unknown group (OR=0.30, 95% CI=0.11-0.83). Using a nationwide OHCA registry, we found

    Patients who require venoarterial extracorporeal membrane oxygenation because of cardiac failure frequently have supranormal blood oxygen tensions (hyperoxia). Recent studies have suggested worse outcomes in patients with hyperoxia after resuscitation from cardiac or respiratory arrests, presumably because of oxidative stress. There are limited data regarding the effect of hyperoxia on outcomes in pediatric patients on venoarterial extracorporeal membrane oxygenation. Retrospective chart review. Pediatric cardiothoracic ICU. Cardiac surgery patients less than 1 year old requiring venoarterial extracorporeal membrane oxygenation in the postoperative period from 2007 to 2013. In 93 infants (median time on extracorporeal membrane oxygenation, 5 d), mortality at 30 days post surgery (primary outcome) was 38%. Using a receiver operating characteristic curve, a mean PaO2 of 193 mm Hg in the first 48 hours of extracorporeal membrane oxygenation was determined to have good discriminatory ability with regard to 30-day mortality. Univariate analysis identified a mean PaO2 greater than 193 mm Hg (p = 0.001), longer cardiopulmonary bypass times (p = 0.09), longer duration of extracorporeal membrane oxygenation (p membrane oxygenation pump flows (p = 0.052) as possible risk factors for 30-day mortality. In multivariable analysis controlling for the variables listed above, a mean PaO2 greater than 193 mm Hg remained an independent risk factor for mortality (p = 0.03). In addition, a mean PaO2 greater than 193 mm Hg was associated with the need for renal dialysis (p = 0.02) but not with neurologic injury (p = 0.41) during the hospitalization. In infants with congenital heart disease who are placed on venoarterial extracorporeal membrane oxygenation postoperatively, hyperoxia (defined as a mean PaO2 > 193 mm Hg in the first 48 hr of extracorporeal membrane oxygenation) was an independent risk factor for 30-day mortality after surgery. Future studies are needed to delineate the

    The prognostic role of electroencephalography during and after targeted temperature management in postcardiac arrest patients, relatively to other predictors, is incompletely known. We assessed performances of electroencephalography during and after targeted temperature management toward good and poor outcomes, along with other recognized predictors. Cohort study (April 2009 to March 2016). Two academic hospitals (Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland; Mayo Clinic, Rochester, MN). Consecutive comatose adults admitted after cardiac arrest, identified through prospective registries. All patients were managed with targeted temperature management, receiving prespecified standardized clinical, neurophysiologic (particularly, electroencephalography during and after targeted temperature management), and biochemical evaluations. We assessed electroencephalography variables (reactivity, continuity, epileptiform features, and prespecified "benign" or "highly malignant" patterns based on the American Clinical Neurophysiology Society nomenclature) and other clinical, neurophysiologic (somatosensory-evoked potential), and biochemical prognosticators. Good outcome (Cerebral Performance Categories 1 and 2) and mortality predictions at 3 months were calculated. Among 357 patients, early electroencephalography reactivity and continuity and flexor or better motor reaction had greater than 70% positive predictive value for good outcome; reactivity (80.4%; 95% CI, 75.9-84.4%) and motor response (80.1%; 95% CI, 75.6-84.1%) had highest accuracy. Early benign electroencephalography heralded good outcome in 86.2% (95% CI, 79.8-91.1%). False positive rates for mortality were less than 5% for epileptiform or nonreactive early electroencephalography, nonreactive late electroencephalography, absent somatosensory-evoked potential, absent pupillary or corneal reflexes, presence of myoclonus, and neuron-specific enolase greater than 75 µg/L; accuracy was highest for

    Full Text Available Cardiac resynchronization therapy (CRT has become an increasingly important therapeutic option for patients (pts to treat dyssynchrony associated moderate and severe heart failure. Few reports however, determined the beneficial effects of CRT in pediatrics and midterm outcome following this therapy. Our aim is to assess the mid-term outcomes of CRT in children with evidence of dyssynchrony associated heart failure. Cardiac resynchronization therapy is beneficial in treating congenital heart disease patients who have evidence of dyssynchrony associated heart failure. Retrospective review of 18 consecutive pediatric patients who underwent CRT at our institution between January 2002 and August 2011 Cardiac resynchronization pacemaker was implanted in 18 pts the majority of pts (14 with congenital heart disease. Fourteen pts had preexisting complete heart block and chronic right ventricular pacing. Epicardial left ventricular leads were implanted in all pts while the atrial and right ventricular leads approach varied according to the pt size and anatomy. Indication for CRT was symptomatic dilated cardiomyopathy with evidence of electrical and/or mechanical dyssynchrony demonstrated by M-mode, 3-D echo, or tissue Doppler. The median age of this cohort was 14 years (range 6 months–16 years, the median follow-up time was 7.2 years (range 1–10 years. Subjectively, 16 out of 18 pts reported symptomatic improvement with decreased hospitalizations. The left ventricular ejection fraction improved from mean of 27% (SD 13% to mean of 50% (SD 13% (P value <0.001. Additionally, cardiomegaly improved significantly in during follow up (P value <0.001. The QRS duration with CRT was less but the change is not significant (P value = 0.1 suggesting that electrical resynchronization is not a prerequisite for clinical improvement in this cohort.

    Obesity is associated with cardiac dysfunction, atherosclerosis, and increased cardiovascular risk. It can be lead to obesity cardiomyopathy and severe heart failure, which in turn raise morbidity and mortality while carrying a negative impact on quality of life. There is increasing clinical and mechanistic evidence on the metabolic and weight loss effects of bariatric surgery on improving cardiac structure and function in obese patients. The objective of this study was to quantify the effects of bariatric surgery on cardiac structure and function by appraising cardiac imaging changes before and after metabolic operations. This is a comprehensive systematic review of studies reporting pre-operative and post-operative echocardiographic or magnetic resonance cardiac indices in obese patients undergoing bariatric surgery. Studies were quality scored, and data were meta-analyzed using random effects modeling. Bariatric surgery is associated with significant improvements in the weighted incidence of a number of cardiac indices including a decrease in left ventricular mass index (11.2%, 95% confidence intervals (CI) 8.2-14.1%), left ventricular end-diastolic volume (13.28 ml, 95% CI 5.22-21.34 ml), and left atrium diameter (1.967 mm, 95% CI 0.980-2.954). There were beneficial increases in left ventricular ejection fraction (1.198%, 95%CI -0.050-2.347) and E/A ratio (0.189%, 95%CI -0.113-0.265). Bariatric surgery offers beneficial cardiac effects on diastolic function, systolic function, and myocardial structure in obese patients. These may derive from surgical modulation of an enterocardiac axis. Future studies must focus on higher evidence levels to better identify the most successful bariatric approaches in preventing and treating the broad spectrum of obesity-associated heart disease while also enhancing treatment strategies in the management of obesity cardiomyopathy.

    Cardiac resynchronization therapy (CRT) for chronic heart failure with left ventricular systolic dysfunction (LVSD) consistently improves survival against optimal medical therapy alone. Limited data exist comparing the outcomes between CRT with pacemaker (CRT-P) and with defibrillator (CRT-D). We aimed to investigate the long-term prognosis of patients who received CRT-P or CRT-D. Data were prospectively collected from consecutive patients with standard indications for CRT, who were implanted at a single large tertiary centre between 2008 and 2012. All-cause mortality was compared between those patients who received either CRT-P or CRT-D. A subgroup analysis was performed in patients with ischaemic cardiomyopathy. During the period in question, 795 patients received CRT devices: 544 (68.4%) CRT-P and 251 (31.6%) CRT-D. The mean follow-up was 1072 ± (SD 556) days. Overall, there was no survival benefit in those patients implanted with a CRT-D compared with CRT-P (hazard ratio 1.09, 95% confidence interval 0.84-1.41, P = 0.51). In patients with ischaemic chronic heart failure [n = 530 (66.7%)], there was a trend for improved survival with CRT-D; however, this was not significant after adjustment. In a subgroup analysis, there were no differences in mode-specific mortality in those patients implanted with CRT-D compared with CRT-P. In this large consecutive patient cohort, we did not find a survival benefit of CRT-D compared with CRT-P. Patients indicated for CRT devices may not reliably benefit from the addition of a defibrillator.

  11. Effectiveness of massage therapy on post-operative outcomes among patients undergoing cardiac surgery: A systematic review

    Full Text Available The incidence and prevalence of cardiovascular disease (CVD are increasing rapidly in developing countries. Most patients with CVD do not respond to medical treatment and have to undergo cardiac surgery. This highly stressful experience results in increased levels of anxiety for patients. The objective of this review was to evaluate the efficacy of massage therapy on postoperative outcomes among patients undergoing cardiac surgery. A comprehensive literature search was made on PubMed-Medline, CINAHL, Science Direct, Scopus, Web of Science and the Cochrane library databases for original research articles published between 2000 and 2015. Original articles that reported the efficacy of massage therapy in patients undergoing cardiac surgery were included. The Cochrane data extraction form was used to extract data. A total of 297 studies were identified in the literature search. However, only seven studies were eligible for analysis. Of the seven studies, six studies demonstrated the effects of massage therapy on improving post-operative outcomes of patients, while one study found no evidence of improvement. Although the methods varied considerably, most of the studies included in this review reported positive results. Therefore, there is some evidence that massage therapy can lead to positive postoperative outcomes. Evidence of the effectiveness of massage therapy in patients undergoing cardiac surgery remains inconclusive. Additional research is needed to provide a strong evidence base for the use of massage therapy to improve post-operative outcomes and recovery among cardiac surgery patients

    Clinical outcome registries are an increasingly vital component of ensuring quality and safety of patient care. However, Australian hospitals rarely have additional resources or the capacity to fund the additional staff time to complete the task of data collection and entry. At the same time, registry funding models do not support staff for the collection of data at the site but are directed towards the central registry tasks of data reporting, managing and quality monitoring. The sustainability of a registry is contingent on building efficiencies into data management and collection. We describe the methods used in a large Victorian public hospital to develop a sustainable data collection system for the Victorian Cardiac Outcomes Registry (VCOR), using existing staff and resources common to many public hospitals. We describe the features of the registry and the hospital specific strategies that allowed us to do this as part of our routine business of providing good quality cardiac care. All clinical staff involved in patient care were given some data collection task with the entry of these data embedded into the staff's daily workflow. A senior cardiology registrar was empowered to allocate data entry tasks to colleagues when data were found to be incomplete. The task of 30-day follow-up proved the most onerous part of data collection. Cath-lab nursing staff were allocated this role. With hospital accreditation and funding models moving towards performance based quality indicators, collection of accurate and reliable information is crucial. Our experience demonstrates the successful implementation of clinical outcome registry data collection in a financially constrained public hospital environment utilising existing resources.

    Right atrial dual-loop reentry tachycardia has been described in patients with open-heart surgery. However, the prevalence, electrophysiologic substrate and ablation outcomes have been poorly characterized. We aimed to investigate the prevalence, electrophysiologic substrate and ablation outcomes for RA dual-loop reentry tachycardia following cardiac surgery. We identified all patients with atrial tachycardia after cardiac surgery. We compared electrophysiologic findings and outcomes of those with RA dual-loop reentry tachycardia versus a control group of patients with RA macro-reentrant arrhythmias in the setting of linear RA free wall (FW) scar. Out of 127 patients with 152 post-surgical atrial tachycardias (ATs), 28 (18.4%) had diagnosis of RA dual-loop reentry and 24/28 (85.7%) had tricuspid annular (TA) reentry combined with FW incisional reentry. An incision length > 51.5mm along the FW predicted the substrate for a second loop. In 22/23 patients (95.7%) with initial ablation in the cavo-tricuspid isthmus, a change in the interval between Halo d to CS p could be recorded, while 15/23 patients (65.2%) had CS activation pattern change. Complete success was achieved in 25/28 (89.3%) and 64/69 (92.8%) in the dual-loop reentry and control groups, respectively. After mean follow-up of 33.9±24.2 months, 24/28 (85.7%) and 60/69 (86.95%) were free of arrhythmias after initial procedure in two groups. The prevalence of RA dual-loop reentry is 18.4% among ATs with prior atriotomy scar. A long incision should alert physician the possibility of the second loop at the FW. Halo and CS activation pattern are important clues for circuit transformation. Copyright © 2018. Published by Elsevier Inc.

    Full Text Available Donation after cardiac death (DCD has expanded in the last decade in the US; however, DCD liver utilization has flattened in recent years due to poor outcomes. We examined clinical and quality of life (QOL outcomes of DCD recipients by conducting a retrospective and cross-sectional review of patients from 2003 to 2010. We compared clinical outcomes of DCD recipients (n=60 to those of donation after brain death (DBD liver recipients (n=669 during the same time period. DCD recipients had significantly lower rates of 5-year graft survival (P<0.001 and a trend toward lower rates of 5-year patient survival (P=0.064 when compared to the DBD cohort. In order to examine QOL outcomes in our cohorts, we administered the Short Form Liver Disease Quality of Life questionnaire to 30 DCD and 60 DBD recipients. The DCD recipients reported lower generic and liver-specific QOL. We further stratified the DCD cohort by the presence of ischemic cholangiopathy (IC. Patients with IC reported lower QOL when compared to DBD recipients and those DCD recipients without IC (P<0.05. While the results are consistent with clinical experience, this is the first report of QOL in DCD recipients using standardized measures. These data can be used to guide future comparative effectiveness studies.

    There has been a remarkable increase in simultaneous liver and kidney transplantations (SLK). As organ demand has increased, so has the use of donation after cardiac death (DCD). However, little is known about the outcomes of DCD in SLK. We performed a retrospective analysis using the United Network for Organ Sharing database to compare the outcomes of DCD SLK to donation after brain death (DBD) and determine the impact of donor and recipient factors on allograft and patient survival. Between 2002 and 2011, a total of 3,026 subjects received SLK from DBD and 98 from DCD. Kidney, liver, and patient survival from DCD donors were inferior to DBD at 1, 3, and 5 years (P=0.0056, P=0.0035, and P=0.0205, respectively). With the use of the Cox model, DCD was a significant risk factor for kidney and liver allograft failure and patient mortality. Recipient factors that were associated with worse allograft and patient outcomes included black race, diabetes, being on a ventilator, hospitalization, delayed graft function, hepatocellular carcinoma, and intensive care unit stay. Older age of the donor was also associated with worse outcomes. Despite the decreased allograft and patient survival compared with DBD, DCD SLK provides an acceptable option for SLK, with a survival probability of more than 50% at 5 years.

    Coronary heart disease is frequent in the working-age population. Traditional outcomes, such as mortality and hospital readmission, are useful for evaluating prognosis. Fit-for-work is an emerging outcome with clinical as well as socioeconomic significance. We describe the possible benefit of a cardiac rehabilitation (CR) program for return to work (RTW) after acute coronary syndrome (ACS). We evaluated 204 patients with recent ACS. They were divided into 4 groups on the basis of their occupational work load: very light (VL), light (L), moderate (M), and heavy (H). Work-related outcomes were assessed with the Work Performance Scale (WPS) of the Functional Status Questionnaire and as "days missed from work" (DMW) in the previous 4 weeks. The variables considered for outcomes were percent ejection fraction, functional capacity expressed in metabolic equivalents (METs), and participation or non-participation in the CR program (CR+ and CR-). One hundred thirty (66%) patients took part in the CR program. Total WPS scores for CR+ and CR- subgroups were VL group: 18±4 vs. 14±4 (p workplace, in particular among clerical workers.

    With the implementation of value-based health care, it is of increasing interest to understand whether performing elective surgeries during off-time impacts surgical outcomes. The objective of this study was to evaluate the impact of start times on nonemergent cardiac operations. The institutional Society of Thoracic Surgeons was used to identify all adult nonemergent cardiac operations performed between January 2008 and December 2015 at our institution. "Off-time" is defined as either operation "late starts," that is, an incision time after 3 PM and before 7 AM, or procedures occurring during the weekends. Univariate and multivariate logistic regression analyses were performed to examine its impact on in-hospital mortality and major adverse events. Available cost data were directly obtained from the departmental BIOME database. Of the 3406 cardiac operations included in the study, 2933 (86.1%) were normal-start and 473 (13.9%) were off-time-start operations. After adjusting for patient and operative characteristics, late operating room start times were not associated with increased in-hospital mortality (P = 0.28, confidence interval [CI] 95% = 0.99-1.03), readmissions (P = 0.21, CI 95% = 0.99-1.07), or major adverse events (P = 0.07, CI 95% = 1.00-1.12). In addition, there was no significant impact on total hospital cost (9.0% increase, P = 0.07). These findings suggest that late operating room start times are not associated with increased mortality or other complications in a tertiary-care academic medical center. Our findings should be considered during operative scheduling to optimize resource distribution and patient care strategies. Copyright © 2017 Elsevier Inc. All rights reserved.

    According to the ACC/AHA/HRS guidelines, cardiac pacing is reasonable in patients with bifascicular block (BF-B) and syncope when other causes have been excluded. The purpose of this study was to assess the long-term outcome of patients with BF-B and unexplained syncope following cardiac pacing. Between 2009 and 2015, we identified 43 consecutive patients (mean age of 78 ± 12 years, 64% males) who presented with syncope and BF-B and had received a pacemaker (PM). During a mean follow-up period of 31 ± 21 months, syncope recurred in seven patients (16%): 7% (95% standard error [SE] ± 3%) at 1 year and 18% (95% SE ± 7%) at 5 years. At univariable analysis, the only predictor of syncope recurrence was empiric pacing (P = 0.03). There were no syncope recurrences in the 12 patients who received a PM following a positive electrophysiological study (EPS) and the five patients with documentation of paroxysmal atrioventricular block (AVB) during cardiac monitoring (insertable loop recorder [ILR]), (EPS/ILR Group, n = 17) compared to seven of 26 (27%) patients who received empiric pacing (Empiric Group, n = 26; P = 0.02). Progression to high-degree AVB was documented during follow-up in 16 (37%) patients: nine of 17 (53%) patients in the EPS/ILR Group and seven of 26 (27%) patients in the Empiric Group (P = 0.11). There were no injuries reported during ILR monitoring. We have shown that syncope recurs not infrequently in patients with BF-B who received pacing for syncope. Nearly one in four patients who had empiric pacing suffered syncope recurrence compared to no recurrences in patients who received a PM following a positive EPS or documentation of transient AVB. © 2016 Wiley Periodicals, Inc.

    Left ventricular end-systolic volume (LVESV) changes at 6 months and clinical status are useful for assessing responses to cardiac resynchronization therapy (CRT). Regression of the LVESV following CRT has not been described beyond 6 months. This study aimed to assess the proportion, predictors, and clinical outcomes of responders whose LVESVs had regressed. We retrospectively analyzed 104 consecutive CRT patients. A responder was defined as a patient with a relative reduction in the LVESV ≥15% at 6 months after CRT. Fifty-six responders participated in this study. A transient responder was defined as a responder without a relative reduction in the LVESV ≥15% at 2 years after CRT or who died of cardiac events during the 24-month follow-up period. Of the 56 responders, 16 (29%) were transient responders. Multivariable logistic regression analysis showed that chronic atrial fibrillation (odds ratio [OR] = 19.2, 95% confidence interval [CI] [1.93, 190], P = 0.012) and amiodarone usage (OR = 60.9, 95% CI [4.18, 886], P = 0.003) were independent predictors of transient responses. Hospitalizations for heart failure were significantly higher among the transient responders than among the lasting responders during a mean follow-up period of 7.6 years (log-rank P chronic AF. © 2017 Wiley Periodicals, Inc.

    Objective: To assess the relationship between serum albumin level and clinical outcome in heart failure (HF) patients receiving cardiac resynchronization therapy (CRT). Methods: In this retrospective cohort study, 357 consecutive chronic heart failure patients receiving CRT between January 2010 and December 2015 were enrolled and divided into two groups based on pre-CRT serum albumin (albumin≥40 g/L, n =244; albuminheart transplantation) and rehospitalization due to worsening HF.Baseline characteristics were compared and all-cause mortality (including heart transplantation) and rehospitalization due to worsening heart failure (HF) were analyzed using Kaplan-Meier curves.Prognostic value of albumin level was evaluated in Cox proportional-hazards regression models. Results: Over a median follow-up time of 21 months, 45 patients (12.6%) died, 4 patients (1.1%) underwent heart transplantation and 100 patients (28.0%) were rehospitalized due to worsening HF. HF patients with pre-CRT albuminheart failure in CRT recipients.Patients with lower pre-CRT albumin level face increased risk of all-cause mortality and HF rehospitalization in chronic heart failure patients receiving cardiac resynchronization.

    Full Text Available The patient database at the First Department of Internal Medicine in Martin, the Central Slovak Institute for Cardiac and Vascular Diseases in Banska Bystrica, and the National Slovak Institute of Cardiovascular Diseases in Bratislava was searched to identify patients with benign tumors of the heart seen during the 5-year period between 2011 and 2016. Forty-one patients with primary cardiac myxomas were identified and their medical records were reviewed for details pertaining to presenting symptoms, staging modalities, treatment approaches, and outcomes. Most of the studied patients were diagnosed with echocardiography (n=35, 85%. The occurrence of the tumor was higher in the female population (n=25, 61%. The most common presenting symptoms were dyspnoea (n=17, 42%, chest pain (n=3, 7%, or pain and paraesthesia of the limbs (n=2, 5%. Acute embolic event due to embolization of tumor fragments resulted in cerebral stroke (n=5, 12%. All patients were treated by resection. Only one comorbid patient died due to multiple-organ dysfunction syndrome two weeks after the resection. The most common postoperative complication was bleeding (n=2, 5% and infection (n=2, 5%. The early diagnosis and appropriate treatment are often curative, with very low risk of recurrence. Postoperative survival is high.

    Current postoperative management of adult cardiac surgery often comprises transfer from the intensive care unit (ICU) to a conventional ward. Intermediate care units (IMCU) permit hospital resource optimization. We analyzed the impact of an IMCU on length of stay (both ICU and in-hospital) and outcomes (in-hospital mortality and 30-day readmissions) after adult cardiac surgery (IMCU-CS). From November 2012 to April 2015, 1324 consecutive patients were admitted to a university hospital for cardiac surgery. In May 2014, an IMCU-CS was established for postoperative care. For the purposes of this study, patients were classified into 2 groups, depending on the admission period: pre-IMCU-CS (November 2012-April 2014, n=674) and post-IMCU-CS (May 2014-April 2015, n=650). There were no statistically significant differences in age, sex, risk factors, comorbidities, EuroSCORE 2, left ventricular ejection fraction, or the types of surgery (valvular in 53%, coronary in 26%, valvular plus coronary in 11.5%, and aorta in 1.8%). The ICU length of stay decreased from 4.9±11 to 2.9±6 days (mean±standard deviation; P<.001); 2 [1-4] to 1 [0-3] (median [Q1-Q3]); in-hospital length of stay decreased from 13.5±15 to 12.7±11 days (mean±standard deviation; P=.01); 9 [7-13] to 9 [7-11] (median [Q1-Q3]), in pre-IMCU-CS to post-IMCU-CS, respectively. There were no statistically significant differences in in-hospital mortality (4.9% vs 3.5%; P=.28) or 30-day readmission rate (4.3% vs 4.2%; P=.89). After the establishment of an IMCU-CS for postoperative cardiac surgery, there was a reduction in ICU and in-hospital mean lengths of stay with no increase in in-hospital mortality or 30-day readmissions.

    A few studies have compared the cardiac rehabilitation (CR) outcome between those who undergo conventional on-pump bypass surgery and off-pump surgery. We compared this outcome among the patients differentiated by the On-pump and off-pump surgical procedures about cardiovascular variables and psychological status. This longitudinal study recruited 318 and 102 consecutive patients who had undergone CABG (on-pump surgery, n = 318 and off-pump surgery, n = 102) and been referred to the CR clinic. The off-pump surgery patients had more improvement in their metabolic equivalents (METs) value. The physical and mental components of health-related quality of life (QOL) (based on SF-36 questionnaire) as well as depression-anxiety (based on Costello-Comrey Depression and Anxiety Scale) were notably improved in the two study groups after the CR program, while changes in the QOL components scores and also depression-anxiety score were not different between the off-pump and on-pump techniques. Regarding QOL and psychological status, there were no differences in the CR outcome between those who underwent off-pump bypass surgery and those who underwent on-pump surgery; nevertheless, the off-pump technique was superior to the on-pump method on METs improvement following CR.

    To characterize the epidemiology and risk factors for acute kidney injury (AKI) after pediatric cardiac surgery in our center, to determine its association with poor short-term outcomes, and to develop a logistic regression model that will predict the risk of AKI for the study population. This single-center, retrospective study included consecutive pediatric patients with congenital heart disease who underwent cardiac surgery between January 2010 and December 2012. Exclusion criteria were a history of renal disease, dialysis or renal transplantation. Of the 325 patients included, median age three years (1 day-18 years), AKI occurred in 40 (12.3%) on the first postoperative day. Overall mortality was 13 (4%), nine of whom were in the AKI group. AKI was significantly associated with length of intensive care unit stay, length of mechanical ventilation and in-hospital death (p<0.01). Patients' age and postoperative serum creatinine, blood urea nitrogen and lactate levels were included in the logistic regression model as predictor variables. The model accurately predicted AKI in this population, with a maximum combined sensitivity of 82.1% and specificity of 75.4%. AKI is common and is associated with poor short-term outcomes in this setting. Younger age and higher postoperative serum creatinine, blood urea nitrogen and lactate levels were powerful predictors of renal injury in this population. The proposed model could be a useful tool for risk stratification of these patients. Copyright © 2015 Sociedade Portuguesa de Cardiologia. Published by Elsevier España. All rights reserved.

    Invasive fetal cardiac intervention (FCI) has been reported in single-institution series, promoting technical and physiologic success. This study describes the creation of an international registry of cases presenting for FCI, intended to compile technical and outcome data from a multicenter cohort. For this initial analysis, the entire database of the International Fetal Cardiac Intervention Registry (IFCIR) was queried for details of diagnoses, procedures, and outcomes. Maternal-fetal dyads from January 2001 through June 2014 were included. Eighteen institutions submitted data by data harvest. Of 370 cases entered, 245 underwent FCI: 100 aortic valvuloplasties from a previous single-center report (excluded from additional reporting here), an additional 86 aortic and 16 pulmonary valvuloplasties, 37 atrial septal cases, and 6 unclassified cases. FCI did not appear to affect overall survival to hospital discharge. Among live-born infants with a fetal diagnosis of aortic stenosis/evolving hypoplastic left heart syndrome, more than twice as many were discharged with biventricular circulation after successful FCI versus those meeting institutional criteria but without any or successful FCI (42.8% vs. 19.4%, respectively). When fetal deaths were counted as treatment failures, the percentages were similar: biventricular circulation at discharge was 31.3% versus 18.5% for those discharged with univentricular palliation. Survival to discharge for live-born fetuses with atrial restriction was similar to that of those undergoing technically successful versus unsuccessful FCI (63.6% vs. 46.7%, respectively), although criteria for diagnosis were nonuniform. We describe the contents of the IFCIR and present post-natal data to suggest potential benefit to fetal therapy among pregnancies considered for possible intervention and support proposals for additional work.

    We and others hypothesized that noxious substances released after prolonged cardiac arrest from malfunctioning liver, kidneys, or intestine (e.g. bacterial toxins, aromatic amino acids), might hamper recovery of the brain. The highly detoxifying effect of hemabsorption (i.e. hemoperfusion) with microencapsulated activated carbon has been demonstrated in other diseases. We used our dog model of ventricular fibrillation cardiac arrest of 15 min (n = 2 x 4) or 12.5 min (n = 2 x 6), reversed by brief (high flow) cardiopulmonary bypass (CPB). In half of the dogs in each insult group, a charcoal filter (HemoKart) was inserted into the circuit of CPB at low flow, from start of reperfusion to 4 h. Intermittent positive pressure ventilation was to 20 h and intensive care to 96 h after cardiac arrest. Bacterial blood cultures were positive in most of the dogs in both groups 30 min to 20 h after cardiac arrest (but not later) and were uninfluenced by hemabsorption. In the control groups to 4 h after cardiac arrest, serum levels of potentially injurious aromatic amino acids (e.g. phenylalanine, tyrosine) and of branched-chain/aromatic amino acid ratios, remained unchanged. From 12 to 48 h after cardiac arrest, aromatic amino acid levels increased (worsened). The branched-chain/aromatic amino acid ratios changed accordingly in the opposite direction. In the hemabsorption groups to 4 h after cardiac arrest, all amino acid levels were reduced, aromatic amino acids more so than branched-chain amino acids, thus increasing (improving) the ratio, compared with controls (P arrest, were not significantly different between groups. The lack of a beneficial outcome effect of hemabsorption to 4 h after cardiac arrest does not support the self-intoxication hypothesis. The amino acid levels later after cardiac arrest suggest that more prolonged hemabsorption and more encompassing detoxification treatments, such as plasma phoresis or total body blood washout, might be evaluated.

    Chronic kidney disease (CKD) severity is associated with increased morbidity and mortality in congestive heart failure. There is a paucity of data regarding renal improvement after cardiac resynchronization therapy (CRT) and its potential impact on clinical outcomes, especially in patients with severe CKD. This was a retrospective analysis of a prospectively collected cohort of 260 patients with CKD undergoing CRT at a single center. Renal function was compared before and after CRT. The primary end point was a composite of death, heart transplant, and left ventricular assist device (LVAD), assessed at 5 years. Patients with more severe CKD demonstrated increased risk of death, transplant, or LVAD following CRT (P = 0.015). Renal response (estimated glomerular filtration rate improvement ≥10 mL/min/1.73 m(2) ) was observed in 14% of all patients and 28% of patients with stage IV CKD. Independent predictors of renal response included left ventricular ejection fraction improvement (odds ratio [OR] 1.06, confidence interval [CI] 1.01-1.10), angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use (OR 4.31, CI 1.08-17.23), and advanced CKD stage (OR 2.19, CI 1.14-4.23). Renal response independently decreased hazard of the primary outcome (HR 0.24, CI 0.08-0.73, P = 0.01). Renal responders with stage IV CKD had 80% 5-year event-free survival, compared to 0% for nonrenal responders in stage IV (P = 0.03). Although severity of CKD is associated with poorer outcome after CRT, improvement in renal function can occur in patients across all CKD stages. Renal responders, including those with stage IV CKD, demonstrate favorable 5-year outcomes. Assessment of renal response may help better prognostic outcomes following CRT. © 2015 Wiley Periodicals, Inc.

    Extracorporeal membrane oxygenation (ECMO) has traditionally been and, for the most part, still is being performed using roller pumps. Use of first-generation centrifugal pumps has yielded controversial outcomes, perhaps due to mechanical properties of the same and the ensuing risk of hemolysis and renal morbidity. Latest-generation centrifugal pumps, using magnetic levitation (ML), exhibit mechanical properties which may have overcome limitations of first-generation devices. This retrospective study aimed to assess the safety and efficacy of veno-arterial (V-A) ECMO for cardiac indications in neonates, infants, and children, using standard (SP) and latest-generation ML centrifugal pumps. Between 2002 and 2014, 33 consecutive neonates, infants, and young children were supported using V-A ECMO for cardiac indications. There were 21 males and 12 females, with median age of 29 days (4 days-5 years) and a median body weight of 3.2 kg (1.9-18 kg). Indication for V-A ECMO were acute circulatory collapse in ICU or ward after cardiac repair in 16 (49%) patients, failure to wean after repair of complex congenital heart disease in 9 (27%), fulminant myocarditis in 4 (12%), preoperative sepsis in 2 (6%), and refractory tachy-arrhythmias in 2 (6%). Central cannulation was used in 27 (81%) patients and peripheral in 6. Seven (21%) patients were supported with SP and 26 (79%) with ML centrifugal pumps. Median duration of support was 82 h (range 24-672 h), with 26 (79%) patients weaned from support. Three patients required a second ECMO run but died on support. Seventeen (51%) patients required peritoneal dialysis for acute renal failure. Overall survival to discharge was 39% (13/33 patients). All patients with fulminant myocarditis and with refractory arrhythmias were weaned, and five (83%) survived, whereas no patient supported for sepsis survived. Risk factors for hospital mortality included lower (pumps in infants and children yields outcomes absolutely comparable to

    Cardiac arrest due to ischaemia is frequently the first manifestation of cardiovascular disease. We sought to describe the characteristics and outcomes of patients admitted to the Intensive Care Unit (ICU) with a diagnosis of cardiac arrest secondary to acute coronary syndrome (ACS). We performed a retrospective analysis of patients admitted to the intensive care unit over a 4 year period. Baseline demographic characteristics, the use of therapeutic hypothermia, rates of percutaneous coronary intervention, co-morbidities and baseline left ventricular function were all documented. Outcomes included Glasgow Coma Scale (GCS) at time of discharge from the ICU, survival to hospital discharge, 6 months survival and left ventricular function at 6 months. We identified 31 admissions to the ICU following cardiac arrest due to ACS during the study period. 71 % of patients survived to hospital discharge and all of these were still alive at 6 months. 65 % had good neurological function (GCS > 13) when discharged from ICU. Mean left ventricular ejection fraction remained stable at 6 months. A significant proportion of patients admitted to the intensive care unit with a diagnosis of cardiac arrest secondary to acute coronary syndrome survive to hospital discharge with meaningful recovery in neurological and cardiac function.

    The purpose of this study was to evaluate the outcome of out-of-hospital cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) in the city of Katowice, Poland, during a period of 1 year prior to the planned reorganization of the national emergency system. Data were collected prospectively according to a modified Utstein style. To ensure accurate data collection, a special method of reporting resuscitation events with the use of a tape-recorder was introduced. Patients were followed for a 1-year period. Between 1 July 2001 and 30 June 2002, out-of-hospital cardiac arrest was confirmed in 1153 patients. Cardiopulmonary resuscitation was attempted in 188 patients. Cardiac arrest of presumed cardiac aetiology (147) was bystander witnessed in 105 (71%) cases and lay-bystander basic life support was performed in 35 (24%). In the group of bystander witnessed arrest ventricular fibrillation (VF) or tachycardia was documented in 59, asystole in 40 and other non-perfusing rhythms in six patients. Of 147 patients with cardiac aetiology, return of spontaneous circulation (ROSC) was achieved in 64 (44%) patients, 15 (10%) were discharged alive and 9 (6%) were alive 1 year later. Most of these patients had a good neurological outcome. Time to first defibrillatory shock was significantly shorter for survivors (median 7 min) compared to non-survivors (median 10 min). The most important resuscitation and patient characteristics associated with survival were VF as initial rhythm, arrest witnessed, and lay-bystander CPR.

    The incidence of shivering in cardiac arrest survivors who undergo therapeutic hypothermia (TH) is varied. Its occurrence is dependent on the integrity of multiple peripheral and central neurologic pathways. We hypothesized that cardiac arrest survivors who develop shivering while undergoing TH are more likely to have intact central neurologic pathways and thus have better neurologic outcome as compared to those who do not develop shivering during TH. Prospectively collected data on consecutive adult patients admitted to a tertiary center from 1/1/2007 to 11/1/2010 that survived a cardiac arrest and underwent TH were retrospectively analyzed. Patients who developed shivering during the cooling phase of TH formed the "shivering" group and those that did not formed the "non-shivering" group. The primary end-point: Pittsburgh Cerebral Performance Category (CPC) scale; good (CPC 1-2) or poor (CPC 3-5) neurological outcome prior to discharge from hospital. Of the 129 cardiac arrest survivors who underwent TH, 34/94 (36%) patients in the "non-shivering" group as compared to 21/35 (60%) patients in the "shivering" group had good neurologic outcome (P=0.02). After adjusting for confounders using binary logistic regression, occurrence of shivering (OR: 2.71, 95% CI 1.099-7.41, P=0.04), time to return of spontaneous circulation (OR: 0.96, 95% CI 0.93-0.98, P=0.004) and initial presenting rhythm (OR: 4.0, 95% CI 1.63-10.0, P=0.002) were independent predictors of neurologic outcome. The occurrence of shivering in cardiac arrest survivors who undergo TH is associated with an increased likelihood of good neurologic outcome as compared to its absence.

    Population-based registries report 95% 5-year survival for children undergoing surgery for CHD. This study investigated paediatric cardiac surgical outcomes in the Australian indigenous population. All children who underwent cardiac surgery between May, 2008 and August, 2014 were studied. Demographic information including socio-economic status, diagnoses and co-morbidities, and treatment and outcome data were collected at time of surgery and at last follow-up. A total of 1528 children with a mean age 3.4±4.6 years were studied. Among them, 123 (8.1%) children were identified as indigenous, and 52.7% (62) of indigenous patients were in the lowest third of the socio-economic index compared with 28.2% (456) of non-indigenous patients (p⩽0.001). The indigenous sample had a significantly higher Comprehensive Aristotle Complexity score (indigenous 9.4±4.2 versus non-indigenous 8.7±3.9, p=0.04). The probability of having long-term follow-up did not differ between groups (indigenous 93.8% versus non-indigenous 95.6%, p=0.17). No difference was noted in 30-day mortality (indigenous 3.2% versus non-indigenous 1.4%, p=0.13). The 6-year survival for the entire cohort was 95.9%. The Cox survival analysis demonstrated higher 6-year mortality in the indigenous group - indigenous 8.1% versus non-indigenous 5.0%; hazard ratio (HR)=2.1; 95% confidence intervals (CI): 1.1, 4.2; p=0.03. Freedom from surgical re-intervention was 79%, and was not significantly associated with the indigenous status (HR=1.4; 95% CI: 0.9, 1.9; p=0.11). When long-term survival was adjusted for the Comprehensive Aristotle Complexity score, no difference in outcomes between the populations was demonstrated (HR=1.6; 95% CI: 0.8, 3.2; p=0.19). The indigenous population experienced higher late mortality. This apparent relationship is explained by increased patient complexity, which may reflect negative social and environmental factors.

    The low lymphocyte counts and high neutrophil leucocyte fractions have been associated with poor prognosis in chronic heart failure. We hypothesized that the baseline ratio of the neutrophil leucocytes to the lymphocytes (NL ratio) would predict the outcome of chronic heart failure patients undergoing cardiac resynchronization therapy (CRT). The qualitative blood counts and the serum levels of N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) of 122 chronic heart failure patients and 122 healthy controls were analysed prospectively in this observational study. The 2-year mortality was considered as primary endpoint and the 6-month reverse remodelling (≥15% decrease in the end-systolic volume) as secondary endpoint. Multivariable regression analyses were applied and net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were calculated. The NL ratio was elevated in chronic heart failure patients when compared with the healthy controls [2.93 (2.12-4.05) vs. 2.21 (1.64-2.81), P chronic heart failure and predicts outcome after CRT. According to the reclassification analysis, 4% of the patients would have been better categorized in the prediction models by combining the NT-proBNP with the NL ratio. Thus, a single blood count measurement could facilitate the optimal patient selection for the CRT. © The Author 2015.

Preclinical, prospective study comparing two similarly prepared, independent control groups (one female group, one male group) included in a larger series of studies. Physiology research laboratory at a major medical center. Male and female mongrel dogs (Canis familiaris), weighing 16 to 22 kg. Cardiopulmonary-cerebral resuscitation following 9 mins of normothermic cardiac arrest in male vs. female dogs. Mean arterial blood pressure, heart rate, urine output, arterial blood oxygen, and PCO2 values, arterial pH, temperature, plasma glucose concentrations, and hematocrit were measured and recorded at the precardiac arrest and postcardiac arrest period, and at 30 mins, and 1, 4, 6, 12, and 24 hrs following resuscitation. Neurologic dysfunction was assessed using a well-standardized neurologic deficit score assigned at 6, 12, and 24 hrs after arrest. Plasma concentrations of malonaldehyde, 4-hydroxynonenal, and erythrocyte-reduced glutathione were measured at the precardiac arrest period, and 6, 12, and 24 hrs following resuscitation. Additionally, serum concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin, alkaline phosphatase, gamma-glutamyl transferase, creatinine kinase, creatinine, albumin, and total protein were measured before arrest, and at 6, 12, and 24 hrs after resuscitation. Plasma concentrations of inorganic phosphorus, blood urea nitrogen, and electrolytes (sodium, chloride, calcium, and potassium) were measured. The estrous cycle phase in the female dogs enrolled in the study was determined by physical examination and vaginal cytology. No prearrest differences were detectable between males and females in basic physiologic variables. No differences in neurologic deficit were detectable between males and females across the 24-hr recovery period following resuscitation. No detectable

    The importance of optimal postoperative glycemic control in cardiac patients remains unclear. Various glycemic targets have been prescribed to reduce wound infection and overall mortality rates. To assess glucose control, as determined by time in range (TIR), in patients with glycemic targets of 6.0 to 8.1 mmol/L, and to determine factors related to poor control. This prospective descriptive study evaluated 227 consecutive patients, 100 with and 127 without diabetes, after cardiac surgery. Patients received insulin to target glucose concentrations of 6.0 to 8.1 mmol/L. Data analyzed included patient age, gender, race, Euro score, cardiopulmonary bypass time (CPB), aortic cross clamp time (ACC), length of ventilation, stay in the intensive care unit (ICU) and stay in the hospital. Patients were divided into two groups, those who maintained > 80% and 80% and Euro score. Failure to maintain target glycemia was significantly more frequent in diabetics (p = 0.001), in patients with glycated hemoglobin (HbA1c) > 8% (p = 0.0001), and in patients taking dopamine (p = 0.04) and adrenaline (p = 0.05). Times of CPB and ACC, length of stay in the ICU and ventilation were significantly higher in patients with TIR 80%. Rates of hypoglycemia, acute kidney injury, and in-hospital mortality were similar in the two groups, although the incidence of wound infection was higher in patients with TIR 80% TIR, whether or not diabetics, had better outcomes than those with <80% TIR, as determined by wound infection, lengths of ventilation and ICU stay. Additionally, they were not subject to frequent hypoglycemic events. Preoperatively high HbA1C is likely a good predictor of poor glycemic control.

    The purpose of our study is (1) to characterise patients with congenital heart disease undergoing heart transplantation by adult cardiac surgeons in a large academic medical centre and (2) to describe successful outcomes associated with our multidisciplinary approach to the evaluation and treatment of adults with congenital heart disease (ACHD) undergoing orthotopic heart transplantation (OHT). Heart failure is the leading cause of death in patients with ACHD leading to increasing referrals for OHT. The Penn Congenital Transplant Database comprises a cohort of patients with ACHD who underwent OHT between March 2010 and April 2016. We performed a retrospective cohort study of the 20 consecutive patients. Original cardiac diagnoses include single ventricle palliated with Fontan (n=8), dextro-transposition of the great arteries after atrial switch (n=4), tetralogy of Fallot (n=4), pulmonary atresia (n=1), Ebstein anomaly (n=1), unrepaired ventricular septal defect (n=1) and Noonan syndrome with coarctation of the aorta (n=1). Eight patients required pretransplant inotropes and two required pretransplant mechanical support. Nine patients underwent heart-liver transplant and three underwent heart-lung transplant. Three patients required postoperative mechanical circulatory support. Patients were followed for an average of 38 months as of April 2016, with 100% survival at 30 days and 1 year and 94% overall survival (19/20 patients). ACHD-OHT patients require highly specialised, complex and multidisciplinary healthcare. The success of our programme is attributed to using team-based, patient-centred care including our multidisciplinary staff and specialists across programmes and departments. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Significant amount of data on the incidence and outcome of out-of-hospital and in-hospital cardiac arrest have been published. Cardiac arrest occurring in the intensive care unit has received less attention. To evaluate and summarize current knowledge of intensive care unit cardiac arrest including quality of data, and results focusing on incidence and patient outcome. We conducted a literature search of the PubMed, CINAHL and Cochrane databases with the following search terms (medical subheadings): heart arrest AND intensive care unit OR critical care OR critical care nursing OR monitored bed OR monitored ward OR monitored patient. We included articles published from the 1st of January 1990 till 31st of December 2012. After exclusion of all duplicates and irrelevant articles we evaluated quality of studies using a predefined quality assessment score and summarized outcome data. The initial search yielded 794 articles of which 780 were excluded. Three papers were added after a manual search of the eligible studies' references. One paper was identified manually from the literature published after our initial search was completed, thus the final sample consisted of 18 papers. Of the studies included thirteen were retrospective, two based on prospective registries and three were focused prospective studies. All except two studies were from a single institution. Six studies reported the incidence of intensive care unit cardiac arrest, which varied from 5.6 to 78.1 cardiac arrests per 1000 intensive care unit admissions. The most frequently reported initial cardiac arrest rhythms were non-shockable. Patient outcome was variable with survival to hospital discharge being in the range of 0-79% and long-term survival ranging from 1 to 69%. Nine studies reported neurological status of survivors, which was mostly favorable, either no neurological sequelae or cerebral performance score mostly of 1-2. Studies focusing on post cardiac surgery patients reported the best long

    To describe and compare the outcomes of a nurse practitioner-managed cardiac surgery follow-up model of care with the standard model of primary care provider follow-up for coronary artery bypass graft surgery patients. Advances in healthcare have had a favourable impact on length of stay following cardiac surgery; however, the shorter length of stay has not been accompanied by enhanced support to bridge the gap between acute care and the community setting. Prospective (2009-2010) randomized study. Elective cardiac surgery patients (N = 200) were randomly assigned to the nurse practitioner follow-up intervention or to the standard model of follow-up care. The main outcomes were health-related quality of life, patient satisfaction, symptoms, and health resource use. Outcome data were elicited via telephone interviews at 2 and 6 weeks postdischarge. Baseline differences between the two groups were non-significant; however, at 2 weeks postdischarge, the intervention group reported significantly fewer symptoms and higher physical functioning status. At 2 and 6 weeks postdischarge, the intervention group was significantly more satisfied with the amount of help, as well as the quality of the services received. Differences in healthcare resource use were not statistically significant. This evidence suggests that the nurse practitioner-managed model of follow-up care effectively bridges the gap between institutional and primary care in the cardiac surgery population. © 2013 Blackwell Publishing Ltd.

    To compare prenatal findings, associated genetic anomalies and postnatal outcome in fetuses with tetralogy of Fallot (TOF) with normal cardiac axis (CAx) and those with abnormal CAx. In this retrospective cohort study, 85 cases diagnosed with TOF by prenatal ultrasound at our clinic between 2005 and 2015 were reviewed. Follow-up ultrasound and postnatal outcome were available for 68 cases. One case complicated with absent pulmonary valve syndrome and a further seven cases diagnosed postnatally with anomalies other than TOF were excluded from the study. The remaining 60 cases of postnatally confirmed TOF were divided according to CAx into two groups: those with normal CAx (n = 33) and those with abnormal CAx (n = 27). CAx was defined as the angle between the interventricular septum and midline of the fetal thorax at the level of the four-chamber view. CAx > 65° or < 25° was considered abnormal. Prenatal sonographic findings, associated genetic anomalies and postnatal outcome were compared between the two groups. Fetuses with TOF and abnormal CAx were more likely to have pulmonary atresia (40.7% vs 15.2%; P = 0.026) and right-sided aortic arch (48.1% vs 21.2%; P = 0.028) than those with normal CAx. Postnatal death occurred in 30.4% of infants with abnormal CAx vs 6.5% with normal CAx (P = 0.028). Incidence of tested genetic anomalies was similar between the two groups. In fetuses with TOF, abnormal CAx is associated with the presence of pulmonary atresia, right-sided aortic arch and a higher risk of postnatal death. Copyright © 2016 ISUOG.

    Background Major postoperative infections (MPIs) are poorly understood complications of cardiac surgery. We examined the epidemiology, microbiology, and outcome of MPIs occurring after cardiac surgery. Methods The study cohort was drawn from the Society of Thoracic Surgeon National Cardiac Database and comprised adults who underwent cardiac surgery at 5 tertiary hospitals between 2000 and 2004. We studied the incidence, microbiology, and risk factors of MPI (bloodstream or chest wound infections within 30 days after surgery), as well as 30-day mortality. We used multivariate regression analyses to evaluate the risk of MPI and mortality. Results MPI was identified in 341 of 10,522 patients (3.2%). Staphylococci were found in 52.5% of these patients, gram-negative bacilli (GNB) in 24.3%, and other pathogens in 23.2%. High body mass index, previous coronary bypass surgery, emergency surgery, renal impairment, immunosuppression, cardiac failure, and peripheral/cerebrovascular disease were associated with the development of MPI. Median postoperative duration of hospitalization (15 days vs 6 days) and mortality (8.5% vs 2.2%) were higher in patients with MPIs. Compared with uninfected individuals, odds of mortality were higher in patients with S aureus MPIs (adjusted odds ratio, 3.7) and GNB MPIs (adjusted odds ratio, 3.0). Conclusions Staphylococci accounted for the majority of MPIs after cardiac surgery. Mortality was higher in patients with Staphylococcus aureus- and GNB-related MPIs than in patients with MPIs caused by other pathogens and uninfected patients. Preventive strategies should target likely pathogens and high-risk patients undergoing cardiac surgery. PMID:22609237

    To describe the reported incidence of out of hospital cardiac arrest (OHCA) and the characteristics and outcome after OHCA in relation to population density in Sweden. All patients participating in the Swedish Cardiac Arrest Register between 2008 and 2009 in (a) 20 of 21 regions (n=6457) and in (b) 165 of 292 municipalities (n=3522) in Sweden, took part in the survey. The regional population density varied between 3 and 310 inhabitants per km(2) in 2009. In 2008-2009, the number of reported cardiac arrests varied between 13 and 52 per 100,000 inhabitants and year. Survival to 1 month varied between 2% and 14% during the same period in different regions. With regard to population density, based on municipalities, bystander CPR (p=0.04) as well as cardiac etiology (p=0.002) were more frequent in less populated areas. Ambulance response time was longer in less populated areas (ppopulation density and survival to 1 month after OHCA or incidence (adjusted for age and gender) of OHCA. There was no significant association between population density and survival to 1 month after OHCA or incidence (adjusted for age and gender) of OHCA. However, bystander CPR, cardiac etiology and longer response times were more frequent in less populated areas. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Carbon monoxide and cyanide poisoning are important causes of death due to fire. Carbon monoxide is more regularly assessed than cyanide at the site of burn or smoke inhalation treatment due to its ease in assessment and simplicity to treat. Although several forensic studies have demonstrated the significance of cyanide poisoning in fire victims using blood cyanide levels, the association between the cause of cardiac arrest and the concentration of cyanide among fire victims has not been sufficiently investigated. This study aimed to investigate the frequency of cyanide-induced cardiac arrest in fire victims and to assess the necessity of early empiric treatment for cyanide poisoning. This study was a retrospective analysis of fire victims with cardiac arrest at the scene who were transported to a trauma and critical care center, Kyorin University Hospital, from January 2014 to June 2017. Patients whose concentration of cyanide was measured were included. Five patients were included in the study; all died despite cardiopulmonary resuscitation. Three of these victims were later found to have lethal cyanide levels (>3 μg/ml). Two of the patients had non-lethal carboxyhemoglobin levels under 50% and might have been saved if hydroxocobalamin had been administered during resuscitation. According to our results, cyanide-induced cardiac arrest may be more frequently present among fire victims than previously believed, and early empiric treatment with hydroxocobalamin may improve outcomes for these victims in cases where cardiac arrest is of short duration.

    The chronic inflammation plays an important role in heart failure and complement components might be useful markers of the prognosis. We set out to evaluate their predictive value in the clinical outcomes of patients with cardiac resynchronization therapy (CRT). We determined the complement levels C3, C3a, sC5b-9 and also the N-terminus of the prohormone brain natriuretic peptide (NT-proBNP) of 126 heart failure patients in a prospective, single-center observational study before and 6 months after CRT implantation. CRT reduced the C3a [212.5 (148.2-283.6) vs. 153 (119.8-218.3) ng/mL, p  165 ng/mL hazard ratio = 4.21 (1.65-10.72), p = 0.003] independent of the NT-proBNP and other factors. After reclassification, we observed a significant net reclassification improvement [NRI = 0.71 (0.43-0.98), p < 0.0001] and integrated discrimination improvement [IDI = 0.08 (0.03-0.12), p = 0.0002]. In patients with CRT, elevated C3a levels increase the risk of mortality independent of the NT-proBNP levels or other factors. CRT exerts anti-inflammatory effect by reducing the complement activation.

    Combining xenon and mild therapeutic hypothermia (MTH) after cardiac arrest (CA) confers a degree of protection that is greater than either of the two interventions alone. However, xenon is very costly which might preclude a widespread use. We investigated whether the inexpensive gas argon would enhance hypothermia induced neurologic recovery in a similar manner. Following nine minutes of CA and three minutes of cardiopulmonary resuscitation 21 male Sprague-Dawley rats were randomized to receive MTH (33°C for 6h), MTH plus argon (70% for 1h), or no treatment. A first day condition score assessed behaviour, motor activity and overall condition. A neurological deficit score (NDS) was calculated daily for seven days following the experiment before the animals were killed and the brains harvested for histopathological analysis. All animals survived. Animals that received MTH alone showed best overall neurologic function. Strikingly, this effect was abolished in the argon-augmented MTH group, where animals showed worse neurologic outcome being significant in the first day condition score and on day one to three and five in the NDS in comparison to MTH treated rats. Results were reflected by the neurohistopathological analysis. Our study demonstrates that argon augmented MTH does not improve functional recovery after CA in rats, but may even worsen neurologic function in this model. Copyright © 2017 Elsevier B.V.

    22q11.2 microdeletion is the most common microdeletion in humans. The purpose of this study was to evaluate postoperative outcome in children with 22q11.2 microdeletion who had undergone complete surgical correction of a congenital heart defect. The study included 34 patients who underwent complete correction of conotruncal heart defects. Of these, 17 patients diagnosed with 22q11.2 microdeletion represent the investigated group. Another 17 patients without 22q11.2 microdeletion represent the control group. Investigated and control groups differ significantly for total length of stay in the hospital (average 37.35 and 14.12 days, respectively); length of postoperative stay in the intensive care unit (average 10.82 and 6.76 days, respectively); sepsis (eight and two patients, respectively); administration of antibiotics (15 and seven patients, respectively); duration of antibiotic therapy (average 17.65 and 14.59 days, respectively); occurrence of hypocalcemia (16 and 0 patients, respectively); and initiation of peroral nutrition during the postoperative course (average 10.29 and 3.88 days, respectively). No difference was found for duration of ventilatory support (average 6.12 and 4.24 days, respectively), administration of total parenteral nutrition, and postoperative mortality rate. The study results suggest that genotype of 22q11.2 microdeletion affects postoperative outcome after cardiac surgery. Possible targets for intervention in postoperative intensive care management are prevention and treatment of systemic infections, monitoring, and treatment of hypocalcemias, rational administration of antibiotics and careful planning of nutrition. Consequently, this could shorten patients' intensive care stay and overall duration of hospitalization.

    Large-scale data on outcomes with cardiac resynchronization therapy with defibrillator in patients with diabetes mellitus are limited. We compared outcomes after cardiac resynchronization therapy with defibrillator implantation among patients with heart failure who have diabetes mellitus versus those without diabetes mellitus. Survival curves and covariate adjusted hazard ratio (HR) or odds ratio were used to assess the risks for death, readmission, and device-related complications by diabetes mellitus status among 18 428 patients at least 65 years old receiving cardiac resynchronization therapy with defibrillator from the National Cardiovascular Data Registry, implantable cardioverter-defibrillator registry between 2006 and 2009, with up to 3 years of follow-up. Accounting for differences between groups, compared with those without diabetes mellitus (n=11 345), patients with diabetes mellitus (n=7083) had a higher risk of death both at 1 year (HR, 1.16 [95% confidence interval (CI), 1.05-1.29]; P=0.0037) and 3 years (HR, 1.21 [1.14-1.29]; Pdiabetes mellitus (odds ratio: 0.90 [0.77-1.06]; P=0.37). Interactions of age, sex, ischemic cardiomyopathy, renal failure, or QRS duration were not significant. In older patients with heart failure receiving cardiac resynchronization therapy with defibrillator, diabetes mellitus was independently associated with greater risks of death and rehospitalization, but similar risks of procedural complications. © 2016 American Heart Association, Inc.

    Full Text Available In the United States, cardiac surgery-related blood transfusion rates reached new highs in 2010, with 34% of patients receiving blood products. Patients undergoing both complex (coronary artery bypass grafting [CABG] plus valve repair or replacement and non-complex (isolated CABG cardiac surgeries are likely to have comorbidities such as anemia. Furthermore, the majority of patients undergoing isolated CABG have a history of myocardial infarction. These characteristics may increase the risk of complications and blood transfusion requirement. It becomes difficult to demonstrate the association between transfusions and mortality because of the fact that most patients undergoing cardiac surgery are also critically ill. Transfusion rates remain high despite the advances in perioperative blood conservation, such as the intraoperative use of cell saver in cardiac surgery. Some recent prospective studies have suggested that the use of blood products, even in low-risk patients, may adversely affect clinical outcomes. In light of this information, we reviewed the literature to assess the clinical outcomes in terms of 30-day and 1-year morbidity and mortality in transfused patients who underwent uncomplicated CABG surgery.

    Factors contributing to postoperative complications include blood loss and a heightened inflammatory response. The objective of this study was to test the hypothesis that aprotinin would decrease perioperative blood product use, reduce biomarkers of inflammation, and result in improved clinical outcome parameters in neonates undergoing cardiac operations. This was a secondary retrospective analysis of a clinical trial whereby neonates undergoing cardiac surgery received either aprotinin (n = 34; before May 2008) or tranexamic acid (n = 42; after May 2008). Perioperative blood product use, clinical course, and measurements of cytokines were compared. Use of perioperative red blood cells, cryoprecipitate, and platelets was reduced in neonates receiving aprotinin compared with tranexamic acid (P challenge contentions that antifibrinolytics are equivalent with respect to early postoperative outcomes.

    Aims The aim was to test the hypothesis that carotid artery plaque expression of lipoprotein-associated phospholipase A2 (Lp-PLA2) predicts cardiac events. Methods and results Prospective cohort study of 162 consecutive patients undergoing elective carotid endarterectomy. Lipoprotein-associated phospholipase A2 content was quantified by immunoblotting and lysophosphatidylcholine (lysoPC) by liquid chromatography tandem mass spectrometry. Additional biomolecular profiling by immunoblotting included C-reactive protein, p67phox, and matrix metalloproteinase-2 and -9. Macrophage plaque content was determined by quantitative immunostaining, plaque collagen content by quantitative Sirius red staining. Follow-up for cardiac death and non-fatal acute myocardial infarction was accomplished over a period of 48 ± 14 months. Expression of Lp-PLA2 and lysoPC was higher in carotid plaques of patients with than without cardiac events [median 1.6 (25th, 75th percentile 0.9, 2.5) vs. 0.8 (0.5, 2.0), P = 0.01 and 413 (281, 443) vs. 226 (96, 351) mmol/L, P = 0.03]. Smoking and point increase in carotid Lp-PLA2 expression but no other traditional cardiovascular risk factor, histological or molecular marker remained predictive of cardiac events in the multivariate Cox proportional hazard analyses [HR 3.65 (1.36–9.83), P = 0.01 and HR 1.34 (1.01–1.77), P = 0.039]. Carotid plaque Lp-PLA2 expression above the median constituted a more than three times higher risk for cardiac events [HR 3.39 (1.13–10.17), P = 0.03]. Conclusion Lipoprotein-associated phospholipase A2 expression in carotid artery plaques is a predictor of long-term cardiac outcome. The current study supports the concept of atherosclerosis as a systemic disease with multi-focal complications and personalized medicine. PMID:19689974

    Cardiac arrest (CA) is the leading cause of death in the United States. Induction of hypothermia has been found to improve the functional recovery of CA patients after resuscitation. However, there is no clear guideline for the clinicians yet to determine the prognosis of the CA when patients are treated with hypothermia. The present work aimed at the development of a prognostic marker for the CA patients undergoing hypothermia. A quantitative measure of the complexity of Electroencephalogram (EEG) signals, called wavelet sub-band entropy, was employed to predict the patients' outcomes. We hypothesized that the EEG signals of the patients who survived would demonstrate more complexity and consequently higher values of wavelet sub-band entropies. A dataset of 16-channel EEG signals collected from CA patients undergoing hypothermia at Long Beach Memorial Medical Center was used to test the hypothesis. Following preprocessing of the signals and implementation of the wavelet transform, the wavelet sub-band entropies were calculated for different frequency bands and EEG channels. Then the values of wavelet sub-band entropies were compared among two groups of patients: survived vs. non-survived. Our results revealed that the brain high frequency oscillations (between 64100 Hz) captured from the inferior frontal lobes are significantly more complex in the CA patients who survived (p-value <; 0.02). Given that the non-invasive measurement of EEG is part of the standard clinical assessment for CA patients, the results of this study can enhance the management of the CA patients treated with hypothermia.

    The effect of out-of-hospital intubation in patients with out-of-hospital cardiac arrest remains controversial. The Taipei City paramedics are the earliest authorized to perform out-of-hospital intubation among Asian areas. This study evaluates the association between successful intubation and out-of-hospital cardiac arrest survival in Taipei. We analyzed 6 years of Utstein-based registry data from nontrauma adult patients with out-of-hospital cardiac arrest who underwent out-of-hospital airway management including intubation, laryngeal mask airway, or bag-valve-mask ventilation. The primary analysis was intubation success on patient outcomes. The primary outcome was survival to discharge and the secondary outcomes included sustained return of spontaneous circulation and favorable neurologic survival. Sensitivity analysis was performed with intubation attempts rather than intubation success. Subgroup analysis of advanced life support-serviced districts was also performed. A total of 10,853 cases from 2008 to 2013 were analyzed. Among out-of-hospital cardiac arrest patients receiving airway management, successful intubation, laryngeal mask airway, and bag-valve-mask ventilation was reported in 1,541, 3,099, and 6,213 cases, respectively. Compared with bag-valve-mask device use, successful out-of-hospital intubation was associated with improved chances of sustained return of spontaneous circulation (adjusted odds ratio [aOR] 1.91; 95% confidence interval [CI] 1.66 to 2.19), survival to discharge (aOR 1.98; 95% CI 1.57 to 2.49), and favorable neurologic outcome (aOR 1.44; 95% CI 1.03 to 2.03). The results were comparable in sensitivity and subgroup analyses. In nontrauma adult out-of-hospital cardiac arrest in Taipei, successful out-of-hospital intubation was associated with improved odds of sustained return of spontaneous circulation, survival to discharge, and favorable neurologic outcome.

    To assess the effect of extremity vascular complications (EVCs, including ischemia or vessel trauma) on the outcomes of patients receiving cardiac support devices (CSDs, including ventricular assist device [VAD] and extracorporeal membrane oxygenation [ECMO]). Institutional Review Board-approved, retrospective review of a prospectively maintained database of all temporary and permanent CSD recipients from 7/1/10 to 6/30/12. Patient demographics, procedural data, and outcomes were analyzed. The primary endpoint was all-cause mortality at 30-days post-CSD initiation. Of 208 patients who received CSDs, 31 (14.9%) experienced EVC: 13 (8.9%) of the 146 permanent VADs, 10 (26.3%) of the 38 temporary VADs, and 8 (33.3%) of the 24 ECMO patients. The 30-day mortality for CSD-EVC patients was not significantly higher than that of the CSD patients who did not experience EVC for permanent VAD (15.4% vs 4.5%; P = .15) and ECMO patients (50.0% vs 68.75%; P = 1.00), but was significantly higher for temporary VAD patients (80.0% vs 35.7%; P = .03). Within the CSD-EVC cohort, patients who received a temporary VAD had a significantly higher 30-day mortality and decision to withdraw care after EVC compared with those who received a permanent VAD (P = .01 and P EVC was associated with higher mortality rates in the permanent VAD population (53.8% vs 25.6%; P = .025) but not the temporary VAD or ECMO groups. In temporary VAD recipients, EVCs result in higher 30-day mortality, more frequent withdrawal of care, and shortened survival time relative to the global temporary VAD group. EVC in permanent VAD recipients did not affect early (30-day) mortality rates, but strongly predicted a higher cumulative mortality risk for the 2-year study period. Overall ECMO mortality rates were high, and not significantly impacted by the occurrence of EVC. The nature of the EVC (cannulation site complication vs embolic injury) did not impact mortality. This data provides quality improvement targets for

    Depression is associated with increased mortality in stable coronary heart disease. Cardiac rehabilitation and exercise training has been shown to decrease depression, psychological stress, and mortality after a coronary heart disease event. The presence of depression at completion of cardiac rehabilitation and exercise training is associated with increased mortality. However, it is unknown if depression with comorbid psychological risk factors such as anxiety or hostility confers an additional mortality disadvantage. We evaluated the mortality effect of anxiety and hostility on depression after cardiac rehabilitation and exercise training. We studied 1150 patients with coronary heart disease following major coronary heart disease events who had completed formal cardiac rehabilitation and exercise training. Using Kellner questionnaires, stress levels were measured in 1 of 3 domains: anxiety, hostility, and depression (with an aggregated overall psychological stress score) and divided into 3 groups: nondepressed (n = 1072), depression alone (n = 18), and depression with anxiety or hostility (n = 60). Subjects were analyzed for all-cause mortality over 161 months of follow-up (mean 6.4 years) by National Death Index. Depression after cardiac rehabilitation was not common (6.8%; mortality 20.8%) but when present, frequently associated with either anxiety or hostility (77% of depressed patients; mortality 22.0%). After adjustment for age, sex, ejection fraction, and baseline peak oxygen consumption, depression alone (hazard ratio [HR] 1.73, P = .04), as well as depression with comorbid psychological stress, was associated with higher mortality (HR 1.98, P = .03). Furthermore, our data showed an increased mortality when both anxiety and hostility were present in addition to depression after cardiac rehabilitation (HR 2.41, P = .04). After cardiac rehabilitation, depression, when present, is usually associated with other forms of psychological stress, which confers

    A variety of existing perioperative informatics tools offer clinicians and researchers the opportunity to improve the delivery of care and clinical outcomes for patients undergoing cardiac and vascular surgery. Many of these tools can be used to improve the reliability of the care delivery process through the application of clinical decision support tools and/or quality improvement methodologies at a number of junctures. In this review, the authors will offer a concise overview of the existing perioperative informatics literature, with a focus on tools considered to be of utility in confronting the unique challenges inherent to cardiac and vascular surgery. The authors also highlight areas that they believe are of interest for future targeted inquiry. Copyright © 2017 Elsevier Inc. All rights reserved.

    While sex differences in the treatment and outcomes of subjects with acute coronary syndromes are well documented, little is known about the impact of cardiac troponin (cTn) levels obtained in the emergency department (ED) on the observed sex differences. We sought to determine whether cTn levels by chest pain features modify sex differences in diagnosis, treatment, and outcomes in patients presenting with chest pain suggestive of ischemia. All adults presenting to two hospitals in Vancouver, Canada, between May 2008 and March 2013 with ischemic chest pain and with cTn testing were included in the study. Outcomes were obtained through data linkage with population-based administrative data sets, including Vital Statistics (death), Discharge Abstract Database (hospitalizations), and PharmaNet (medications). Cumulative event rates for the composite major adverse cardiac event (MACE) endpoint (death, myocardial infarction [MI], incident admission for heart failure or for angina requiring diagnostic catheterization or revascularization) were estimated for each sex and cTn level using the Kaplan-Meier method; Cox models were used to estimate hazard ratios and 95% confidence interval (CIs) for 1-year MACE and 7-day catheterization. Logistic models were used to estimate odds ratios (ORs) and 95% CI for 90-day medication use. Over the 5-year study period, 25,539 patients presented to the ED with chest pain of which 7,272 (2,933 females and 4,339 males) met the inclusion criteria. Among patients with chest pain with cardiac features/history and cTn > 99th percentile, females were less likely to be diagnosed with MI (46.4% vs. 57.5%). Females in the cTnI > 99th percentile group had the worst outcomes with a 1-year MACE rate of 22.7% (95% CI = 18.5-27.7) versus 18.8% (95% CI = 16.2-21.6), although this difference was attenuated and not statistically significant after adjustment for baseline differences. Overall, females underwent fewer diagnostic catheterizations than

    The objective of this study was to investigate variation in practice surrounding elective cardiac catheterization in patients with single-ventricle (SV) congenital heart disease. Patient and procedural characteristics and outcomes during SV catheterization were collected prospectively from eight centers using a web-based registry (Congenital Cardiac Catheterization Project on Outcomes). We attempted to identify a population of elective procedures by limiting the cohort in case type and timing. Cases were then stratified by stage of SV palliation (pre-bidirectional cavopulmonary anastomosis [pre-BCPA], pre-Fontan and post-Fontan) and limited by age. Subcohort analysis was performed by mode of airway management (assisted vs. spontaneous ventilation). Institutional variation was assessed. Between 2/2007 and 6/2010, 1459 (10.1%) of 14 467 cases in the registry met the inclusion and exclusion criteria, including 326 pre-BCPA, 571 pre-Fontan and 562 post-Fontan procedures. Median patient age was 0.4 (interquartile range 0.3, 0.5), 2.6 (1.0, 3.4) and 9.6 (5.2, 15.4) years and weight was 5.6 (4.8, 6.4), 12.2 (10.5, 14), and 26.3 (16.6, 51.8) kg in the pre-BCPA, pre-Fontan and post-Fontan cohorts, respectively. Cases were more commonly diagnostic in the pre-BCPA cohort (57%) whereas they were more commonly interventional in the pre-Fontan (69%) and post-Fontan (77%) cohorts. At least one adverse event (AE) occurred in 210 cases (14.4%) overall, including 20% of pre-BCPA, 11% of pre-Fontan and 14% of post-Fontan catheterizations. Mode of airway management was associated with statistically significant, but clinically small differences in hemodynamic measures in the pre- and post-Fontan cohorts, but not in the pre-BCPA group. Considerable practice variation exists across centers with variability in airway management, AE rate, case type, interventions performed and fluoroscopy time, in all SV cohorts. Elective catheterization in SV patients, frequently performed with

    Deficits in cognitive function are a well-known dysfunction in survivors of cardiac arrest. However, data concerning memory function in this neurological vulnerable patient collective remain scarce and inconclusive. Therefore, we aimed to assess multiple aspects of retrospective and prospective memory performance in patients after cardiac arrest. We prospectively enrolled 33 survivors of cardiac arrest, with cerebral performance categories (CPC) 1 and 2 and a control-group (n=33) matched in sex, age and educational-level. To assess retrospective and prospective memory performance we administrated 4 weeks after cardiac arrest the "Rey Adult Learning Test" (RAVLT), the "Digit-Span-Backwards Test", the "Logic-Memory Test" and the "Red-Pencil Test". Results indicate an impairment in immediate and delayed free recall, but not in recognition. However, the overall impairment in immediate recall was qualified by analyzing RAVLT performance, showing that patients were only impaired in trials 4 and 5 of the learning sequence. Moreover, working and prospective memory as well as prose recall were worse in cardiac arrest survivors. Cranial computed tomography was available in 61% of all patients (n=20) but there was no specific neurological damage detectable that could be linked to this cognitive impairment. Episodic long-term memory functioning appears to be particularly impaired after cardiac arrest. In contrast, short-term memory storage, even tested via free-call, seems not to be affected. Based on cranial computed tomography we suggest that global brain ischemia rather than focal brain lesions appear to underlie these effects. Copyright © 2014 Elsevier Ireland Ltd.

    To examine survival and neurodevelopmental outcomes in neonates having post-operative cardiopulmonary resuscitation (CPR). This inception cohort study included all neonates (6 weeks old or less) who received postoperative CPR (Group 1) after cardiac surgery from 1996 to 2005, matched for heart defect, year of surgery, chromosomal abnormality, and socioeconomic status to two neonates who did not receive postoperative CPR (Group 2). Two-year neurodevelopment was prospectively assessed with Bayley Scales of Infant Development II and Adaptive Behavior Assessment System II. Pre-, intra-, and post-operative variables were collected prospectively. Cardiac arrest variables were collected retrospectively. Predictors of mortality were analyzed by univariate analysis and conditional multiple logistic regression. There were 29 patients in Group 1, and 58 patients in Group 2. In survivors, there were no significant differences between Groups 1 and 2 in outcomes [mean (SD)] of mental developmental index [84.5 (12.2) vs. 81.0 (18.9)], psychomotor developmental index [82.8 (13.8) vs. 80.1 (21.9)], General Adaptive Composite [84.6 (15.3) vs. 84.3 (19.2)], Motor scale [8.4 (3.2) vs. 8.0 (3.8)], or delay on any of these scales. Two-year mortality [58.6% Group 1; 8.6% Group 2], was associated on conditional multiple logistic regression with CPR (OR 26.6; 95% CI, 5.4, 129.5). In Group 1, on multiple logistic regression, 2-year mortality was associated with minutes of chest compressions (OR 1.04, 95% CI, 1.01, 1.08). Among neonates having cardiac surgery, CPR is associated with greater mortality. There is no evidence that CPR survivors have different 2-year neurodevelopmental outcomes than those neonates not having CPR. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Nosocomial urinary tract infection (UTI) increases hospitalization, cost and morbidity. In this cohort study, we aimed to determine the incidence, risk factors, etiology and outcomes of UTIs in post-operative cardiac children. To this end, we studied all post-operative patients admitted to the Pediatric Cardiac Intensive Care Unit (PCICU) in 2012, and we divided the patients into two groups: the UTI (UTI group) and the non-UTI (control group). We compared both groups for multiple peri-operative risk factors. We included 413 children in this study. Of these, 29 (7%) had UTIs after cardiac surgery (UTI group), and 384 (93%) were free from UTIs (control group). All UTI cases were catheter-associated UTIs (CAUTIs). A total of 1578 urinary catheter days were assessed in this study, with a CAUTI density rate of 18 per 1000 catheter days. Multivariate logistic regression analysis demonstrated the following risk factors for CAUTI development: duration of urinary catheter placement (purinary tract (CAKUT) (purinary catheter, the presence of CAKUT, and the presence of syndromes comprised the main risk factors for CAUTI. Gram-negative organisms were the main causes for CAUTI, and one-third of them found to be resistant in this single-center study.

    Full Text Available The number of patients with congenital heart disease (CHD is increasing worldwide and most of them will require cardiac surgery, once or more, during their lifetime. The total volume of cardiac surgery in CHD patients at a national level and the associated mortality and predictors of death associated with surgery are not known. We aimed to investigate the surgical volume and associated mortality in CHD patients in England.Using a national hospital episode statistics database, we identified all CHD patients undergoing cardiac surgery in England between 1997 and 2015.We evaluated 57,293 patients (median age 11.9years, 46.7% being adult, 56.7% female. There was a linear increase in the number of operations performed per year from 1,717 in 1997 to 5,299 performed in 2014. The most common intervention at the last surgical event was an aortic valve procedure (9,276; 16.2%, followed by repair of atrial septal defect (9,154; 16.0%, ventricular septal defect (7,746; 13.5%, tetralogy of Fallot (3,523; 6.1% and atrioventricular septal defect (3,330; 5.8% repair. Associated mortality remained raised up to six months following cardiac surgery. Several parameters were predictive of post-operative mortality, including age, complexity of surgery, need for emergency surgery and socioeconomic status. The relationship of age with mortality was "U"-shaped, and mortality was highest amongst youngest children and adults above 60 years of age.The number of cardiac operations performed in CHD patients in England has been increasing, particularly in adults. Mortality remains raised up to 6-months after surgery and was highest amongst young children and seniors.

    Although attention has recently been focused on the role of psychosocial factors in patients with cardiovascular disease (CVD), the factors that have the greatest influence on prognosis have not yet been elucidated. The aim of this study was to evaluate the effects of depression, anxiety, and anger on the prognosis of patients with CVD. Four hundred fourteen consecutive patients hospitalized with CVD were prospectively enrolled. Depression was evaluated using the Patient Health Questionnaire, anxiety using the Generalized Anxiety Disorder Questionnaire, and anger using the Spielberger Trait Anger Scale. Cox proportional-hazards regression was used to examine the individual effects of depression, anxiety, and anger on a combined primary end point of cardiac death or cardiac hospitalization and on a combined secondary end point of all-cause death or hospitalization during follow-up (median 14.2 months). Multivariate analysis showed that depression was a significant risk factor for cardiovascular hospitalization or death after adjusting for cardiac risk factors and other psychosocial factors (hazard ratio 2.62, p = 0.02), whereas anxiety was not significantly associated with cardiovascular hospitalization or death after adjustment (hazard ratio 2.35, p = 0.10). Anger was associated with a low rate of cardiovascular hospitalization or death (hazard ratio 0.34, p risk factor for adverse cardiac events than either anxiety or anger. Anger may help prevent adverse outcomes. Routine screening for depression should therefore be performed in patients with CVD, and the potential effects of anger in clinical practice should be reconsidered. Copyright © 2013 Elsevier Inc.

    The accurate prediction of outcome after out-of-hospital cardiac arrest (OHCA) is of major importance. The recently described Full Outline of UnResponsiveness (FOUR) is well adapted to mechanically ventilated patients and does not depend on verbal response. To evaluate the ability of FOUR assessed by intensivists to accurately predict outcome in OHCA. We prospectively identified patients admitted for OHCA with a Glasgow Coma Scale below 8. Neurological assessment was performed daily. Outcome was evaluated at 6 months using Glasgow-Pittsburgh Cerebral Performance Categories (GP-CPC). Eighty-five patients were included. At 6 months, 19 patients (22%) had a favorable outcome, GP-CPC 1-2, and 66 (78%) had an unfavorable outcome, GP-CPC 3-5. Compared to both brainstem responses at day 3 and evolution of Glasgow Coma Scale, evolution of FOUR score over the three first days was able to predict unfavorable outcome more precisely. Thus, absence of improvement or worsening from day 1 to day 3 of FOUR had 0.88 (0.79-0.97) specificity, 0.71 (0.66-0.76) sensitivity, 0.94 (0.84-1.00) PPV and 0.54 (0.49-0.59) NPV to predict unfavorable outcome. Similarly, the brainstem response of FOUR score at 0 evaluated at day 3 had 0.94 (0.89-0.99) specificity, 0.60 (0.50-0.70) sensitivity, 0.96 (0.92-1.00) PPV and 0.47 (0.37-0.57) NPV to predict unfavorable outcome. The absence of improvement or worsening from day 1 to day 3 of FOUR evaluated by intensivists provides an accurate prognosis of poor neurological outcome in OHCA.

    Octogenarians offered complex cardiac surgery frequently experience a prolonged intensive care unit length of stay; however, minimal data exist on the outcomes of these patients. We sought to determine the rates and predictors of 1-year noninstitutionalized survival ("functional survival") and rehospitalization for octogenarian patients with prolonged intensive care unit length of stay after cardiac surgery and who were discharged from hospital. The outcomes of discharged patients aged 80 years or more who underwent cardiac surgery with prolonged intensive care unit length of stay (≥5 consecutive days) from January 1, 2000, to December 31, 2011, were examined retrospectively from linked clinical and administrative provincial databases. Regression analysis was used to determine predictors of 1-year functional survival and rehospitalization after discharge from the hospital. A total of 80 of 683 (11.7%) discharged octogenarian patients had prolonged intensive care unit length of stay. Functional survival at 1 year was 92% and 81% for those with nonprolonged and prolonged intensive care unit lengths of stay, respectively (P intensive care unit lengths of stay, respectively, with 41% of all rehospitalizations occurring within 30 days of initial discharge. A rural residence (hazard ratio, 1.82; P intensive care unit length of stay have acceptable functional survival at 1 year but have high rates of early rehospitalization. Access to health services may influence functional survival and early rehospitalizations. These data suggest that close follow-up of these vulnerable patients after hospital discharge is warranted.

    Full Text Available Abstract Background A large proportion of patients who suffer from out of hospital cardiac arrest (OHCA outside home are theoretically candidates for public access defibrillation (PAD. We describe the change in characteristics and outcome among these candidates in a 14 years perspective in Sweden. Methods All patients who suffered an OHCA in whom cardiopulmonary resuscitation (CPR was attempted between 1992 and 2005 and who were included in the Swedish Cardiac Arrest Register (SCAR. We included patients in the survey if OHCA took place outside home excluding crew witnessed cases and those taken place in a nursing home. Results 26% of all OHCAs (10133 patients out of 38710 patients fulfilled the inclusion criteria. Within this group, the number of patients each year varied between 530 and 896 and the median age decreased from 68 years in 1992 to 64 years in 2005 (p for trend = 0.003. The proportion of patients who received bystander CPR increased from 47% in 1992 to 58% in 2005 (p for trend The median time from cardiac arrest to defibrillation among witnessed cases was 12 min in 1992 and 10 min in 2005 (p for trend = 0.029. Survival to one month among all patients increased from 8.1% to 14.0% (p for trend = 0.01. Among patients found in a shockable rhythm survival increased from 15.3% in 1992 to 27.0% in 2005 (p for trend Conclusion In Sweden, there was a change in characteristics and outcome among patients who suffer OHCA outside home. Among these patients, bystander CPR increased, but the occurrence of VF decreased. One-month survival increased moderately overall and highly significantly among patients found in VF, even though the time to defibrillation changed only moderately.

    Paediatric cardiac surgery has a low error tolerance and demands high levels of cognitive and technical performance. Growing evidence suggests that further improvements in patient outcomes depend on system factors, in particular, effective team skills. The hypotheses that small intraoperative non-routine events (NREs) can escalate to more serious situations and that effective teamwork can prevent the development of serious situations were examined to develop a method to assess these skills and to provide evidence for improvements in training and performance. This mixed-method design, using both quantitative and qualitative measures, relied on trained human factor observers who observed and coded NREs and teamwork elements from the time of patient arrival into the operating room to patient handover to the intensive care unit. Real-time teamwork observations were coupled with microsystem preparedness measures, operative duration, assessed difficulty of the operation and patient outcome measures. Behaviour was rated based on whether it hindered or enhanced teamwork. 40 paediatric cardiac surgery cases were observed. Surgeons displayed better teamwork during complicated procedures, particularly during the surgical bypass/repair epoch. More procedural NREs were associated with a more complicated postoperative course (M(uncomplicated)=9.08; M(minor complications)=11.11; M(major morbidity)=14.60, F(2,26)=3.46, pobservation of effective teamwork in the operating room can identify substantive deficiencies in the system and conduct of procedures, even in otherwise successful operations. High performing teams are more resilient displaying effective teamwork when operations become more difficult.

    Acyl-CoA dehydrogenase family, member 9 (ACAD9) mutation is a frequent, usually fatal cause of early-onset cardiac hypertrophy and mitochondrial respiratory chain complex I deficiency in early childhood. We retrospectively studied a series of 20 unrelated children with cardiac hypertrophy and isolated complex I deficiency and identified compound heterozygosity for missense, splice site or frame shift ACAD9 variants in 8/20 patients (40%). Age at onset ranged from neonatal period to 9 years and 5/8 died in infancy. Heart transplantation was possible in 3/8. Two of them survived and one additional patient improved spontaneously. Importantly, the surviving patients later developed delayed-onset neurologic or muscular symptoms, namely cognitive impairment, seizures, muscle weakness and exercise intolerance. Other organ involvement included proximal tubulopathy, renal failure, secondary ovarian failure and optic atrophy. We conclude that ACAD9 mutation is the most frequent cause of cardiac hypertrophy and isolated complex I deficiency. Heart transplantation in children surviving neonatal period should be considered with caution, as delayed-onset muscle and brain involvement of various severity may occur, even if absent prior to transplantation.

    Objective: To evaluate maternal and neonatal mortality and morbidity rates in women with different types of significant heart diseases. Methods: The cross-sectional study was conducted at a tertiary heart care centre in Tabriz, Iran, and comprised 200 pregnant women between March 2007 and March 2012 who had different cardiac diseases and were admitted in labour wards first and then transferred to the heart center for child-bearing (vaginal delivery or caesarean section). They were categorised based on the underlying etiology into valvular heart disease, dilated cardiomyopathy, congenital heart disease and other etiologies. SPSS 18 was used for statistical analysis. Results: The mean age of the 200 subjects was 29.4+-4.28 years. Caesarean section was performed on 152 (76%) cases, while 48 (24%) underwent vaginal delivery. There were 216 neonates as 16 (8%) women had twins. Overall, 164 (75.9%) were female, and 52 (24.1%) male. Maternal and neonatal mortality rates were 4.0% (n=8) and 10% (n=22) respectively. Pregnant women with Congenital heart disease experienced more maternal (p<0.022) and neonatal (p<0.031) mortality rates than other cardiac diseases. Conclusion: Pregnant women with cardiac diseases are prone to higher maternal and neonatal mortality rates in northwest Iran. (author)

    Falls are one of the most common types of complaints received by 9-1-1 emergency medical dispatch centers. They can be accidental or may be caused by underlying medical problems. Though "not alert" falls patients with severe outcomes mostly are "hot" transported to the hospital, some of these cases may be due to other acute medical events (cardiac, respiratory, circulatory, or neurological), which may not always be apparent to the emergency medical dispatcher (EMD) during call processing. The objective of this study was to characterize the risk of cardiac arrest and "hot-transport" outcomes in patients with "not alert" condition, within the Medical Priority Dispatch System (MPDS®) Falls protocol descriptors. This retrospective study used 129 months of de-identified, aggregate, dispatch datasets from three US emergency communication centers. The communication centers used the Medical Priority Dispatch System version 11.3-OMEGA type (released in 2006) to interrogate Emergency Medical System callers, select dispatch codes assigned to various response configurations, and provide pre-arrival instructions. The distribution of cases and percentages of cardiac arrest and hot-transport outcomes, categorized by MPDS® code, was profiled. Assessment of the association between MPDS® Delta-level 3 (D-3) "not alert" condition and cardiac arrest and hot-transport outcomes then followed. Overall, patients within the D-3 and D-2 "long fall" conditions had the highest proportions (compared to the other determinants in the "falls" protocol) of cardiac arrest and hot-transport outcomes, respectively. "Not alert" condition was associated significantly with cardiac arrest and hot-transport outcomes (pdeterminant within the MPDS® "fall" protocol was associated significantly with severe outcomes for short falls (falls. As reported to 9-1-1, the complaint of a "fall" may include the presence of underlying conditions that go beyond the obvious traumatic injuries caused by the fall itself.

    Neurologically intact survival after cardiac arrest is possible even after prolonged resuscitation efforts. However, the factors associated with good neurologic outcome in these patients remain unknown. This study identifies predictors associated with good neurologic outcome after resuscitation beyond 30 min in out-of-hospital cardiac arrest (OHCA) patients treated with targeted temperature management (TTM). This multicenter, registry-based, retrospective cohort study conducted in 24 hospitals across South Korea between 2007 and 2012 includes adult (≥18 years) non-traumatic OHCA patients with prolonged (>30 min) downtime who underwent TTM treatment. Good neurologic outcomes were defined as cerebral performance category scores of ≤2. Of the 930 comatose adult cardiac arrest patients treated with TTM, 423 patients with prolonged downtime were included. A total of 76 (18.0%) had good neurologic outcome. Multivariable analysis reveal that age good neurologic outcome. The sensitivity and specificity for good neurologic outcome in patients with age <65 years, shockable rhythm, and witnessed arrest are 90.8% and 41.2, 67.6 and 79.5%, and 81.6 and 41.2%, respectively. In prolonged cardiac arrest patients, initial shockable rhythm, age <65 years, or witnessed arrest are predictors for neurologic intact survival.

    Full Text Available Background: Hypoalbuminemia may be caused by liver disease, nephrotic syndrome, burns, protein-losing entropathy, malnutrition, and metabolic stress. Alterations in albumin in metabolic stress such as cardiac surgery have been previously investigated. We studied serum albumin concentration in children with congenital heart disease and also the association of hypoalbuminemia with mortality and morbidity after pediatric cardiac surgery.Methods: We measured serum albumin concentration prospectively in 300 children with congenital heart disease who underwent surgery between July and September 2008 in Shaheed Rajaee hospital. Serum albumin concentration was measured before and 48 hours after cardiac surgery and was subsequently compared between 2 groups: cyanotic and acyanotic and also with normal values.Results: Serum albumin concentration decreased on the second post-operative day in 70 (23.3% patients. There was a positive correlation between the post-surgical hypoalbuminemia and cyanotic heart disease. The cyanotic children had lower serum albumin concentration than the acyanotic ones (P value <0.001. There was a significant association between post-operative serum albumin concentration and acute renal failure (P value <0.001 and death (P value <0.001. Drop in serum albumin concentration was more prominent in the males than in the females (P value=0.038 and in the cyanotic patients than in the acyanotic ones (P value <0.001 as well as in those with acute renal failure (P value <0.001, pericardial effusion (P value=0.050, seizure (P value <0.001, and death (P value <0.001. Hypoalbuminemia was not associated with longer hospital (P value=0.142 or intensive care unit stay (P value=0.199 .Conclusion: Post-operative serum albumin concentration was lower in the cyanotic children and male patients in our study. In addition, the post-operative decrease in albumin was associated with an increased risk of pericardial effusion, renal failure, seizure, and

    Cardiovascular Disease (CVD) is the most common cause of death in industrialized countries, and myocardial infarction (MI) is a major CVD with significant morbidity and mortality. Following MI, the left ventricle (LV) undergoes a wound healing response to ischemia that results in extracellular...... matrix (ECM) scar formation to replace necrotic myocytes. While ECM accumulation following MI is termed cardiac fibrosis, this is a generic term that does not differentiate between ECM accumulation that occurs in the infarct region to form a scar that is structurally necessary to preserve left ventricle...

    Atrial fibrillation (AF) is a cardiac arrhythmia with high risk for thromboembolic events, specially stroke. To assess the safety of left atrial appendage closure (LAAC) with the Amplatzer Cardiac Plug for the prevention of thromboembolic events in patients with nonvalvular AF. This study included 15 patients with nonvalvular AF referred for LAAC, 6 older than 75 years (mean age, 69.4 ± 9.3 years; 60% of the male sex). The mean CHADS2 score was 3.4 ± 0.1, and mean CHA2DS2VASc , 4.8 ± 1.8, evidencing a high risk for thromboembolic events. All patients had a HAS-BLED score > 3 (mean, 4.5 ± 1.2) with a high risk for major bleeding within 1 year. The device was successfully implanted in all patients, with correct positioning in the first attempt in most of them (n = 11; 73.3%). There was no periprocedural complication, such as device migration, pericardial tamponade, vascular complications and major bleeding. All patients had an uneventful in-hospital course, being discharged in 2 days. The echocardiographic assessments at 6 and 12 months showed neither device migration, nor thrombus formation, nor peridevice leak. On clinical assessment at 12 months, no patient had thromboembolic events or bleeding related to the device or risk factors. In this small series, LAAC with Amplatzer Cardiac Plug proved to be safe, with high procedural success rate and favorable outcome at the 12-month follow-up.

    Intraoperative management directed to early extubation of children undergoing cardiac surgery has been suggested as a viable alternative to prolonged postoperative mechanical ventilation. The authors evaluated the safety and efficacy of this approach in a randomized prospective trial. A prospective randomized observational study. A single university-affiliated hospital. One hundred consecutive pediatric patients (age 1 month-15 years, weight 3.0-51 kg) requiring cardiac surgery. Patients younger than 1 month of age and those requiring mechanical ventilation before the operation were considered ineligible for the study. Patients were randomly allocated to a group with anesthetic management and extubation in the operating room (early group [EG]) and a group with elective prolonged mechanical ventilation (control group [CG]). A difference in outcome as reflected by the pediatric intensive care unit (PICU) and hospital lengths of stay and postoperative morbidity and mortality was analyzed. A separate analysis was performed in children younger than 3 years old. The extubation time in the CG was 25.0 +/- 26.9 hours. No differences in mortality, the need for re-exploration for bleeding, the need for reintubation, the incidence of abnormal chest radiographic findings, or cardiac and septic complications between groups were found. PICU and postoperative hospital lengths of stay were significantly shorter in patients in the EG (3.3 +/- 1.9 days in the EG v 5.8 +/- 4.1 in the CG, p management with early cessation of mechanical ventilation appears to be safe and decreases hospital and PICU length of stay. However, because the size of the study did not allow for the detection of possible differences in perioperative mortality, only a large multicenter study may provide a definite answer to this question. The present study may be treated as a pilot for such a trial.

    Accumulation of extracellular matrix (ECM) is known to play a crucial role in the pathophysiology of heart failure (HF). However, its prognostic relevance is poorly investigated. A total of 73 HF patients who underwent LV endomyocardial biopsy were enrolled in our study. ECM area was quantified by TissueFAXS and ImageJ software. Patients were followed-up at 6-month intervals. The study endpoint was defined as hospitalization for a cardiac reason and/or cardiac death. Furthermore, the influence of the ECM on invasively measured haemodynamic parameters was tested. During a median follow-up period of 9.0 months, 34 patients (46.6%) reached the combined endpoint. Median ECM area was 30.5%. Patients with ECM area ≥30.5% experienced significantly more events (67.6% vs. 25.0%, P heart haemodynamics and is associated with clinical course in various non-ischaemic HF types. © 2016 The Authors.

    Out-of-hospital cardiac arrest (OHCA) is a major health concern in Japan and other developed countries with aging populations. Improvements in OHCA outcomes require streamlining the chain of survival. Deployment of public-access automated external defibrillators (PADs) and defibrillation by bystanders is one strategy that may streamline the chain by reducing the time to defibrillation in individuals with shockable rhythms. Although the effectiveness of PAD programs in increasing survival to discharge has been reported, there have been criticisms and concerns about the small population impact, cost-effectiveness, and potential negative impact on those with nonshockable rhythms. This article reviews relevant literature regarding the effectiveness and concerns regarding PAD for OHCA.

    A prolonged PR interval is common among cardiac resynchronization therapy (CRT) candidates; however, the association between PR interval and outcomes is unclear, and the data are conflicting. We conducted inverse probability weighted analyses of 26 451 CRT-eligible (ejection fraction ≤35, QRS ≥120 ms) patients from the National Cardiovascular Data Registry ICD Registry to assess the association between a prolonged PR interval (≥230 ms), receipt of CRT with defibrillator (CRT-D) versus implantable cardioverter defibrillator (ICD), and outcomes. We first tested the association between a prolonged PR interval and outcomes among patients stratified by device type. Next, we performed a comparative effectiveness analysis of CRT-D versus ICD among patients when stratified by PR interval. Using Medicare claims data, we followed up with patients up to 5 years for incident heart failure hospitalization or death. Patients with a PR≥230 ms (15%; n=4035) were older and had more comorbidities, including coronary artery disease, atrial arrhythmias, diabetes mellitus, and chronic kidney disease. After risk adjustment, a PR≥230 ms (versus PRheart failure hospitalization or death among CRT-D (hazard ratio, 1.23; 95% confidence interval, 1.14-1.31; Pheart failure hospitalization or death among patients with PRheart failure hospitalization or death among CRT-D patients.

    During general anesthesia the possibility of subconscious perception of intraoperative events is a controversial subject. Some studies found that positive verbal suggestions, or music improved intraoperative relaxation and postoperative recovery. The aim of the current study was to evaluate the effect of prayer and relaxation technique applied while patients are under general anesthesia for open-heart surgery. A randomized, controlled, double-blind trial study included 78 patients who underwent cardiac surgery. During the surgery the patients used a headphone connected to a CD player. They were randomly divided into three groups. One group listened to prayer during the surgery, the other listened to relaxation technique and one, placebo. There was only one significant finding: the prayer group is less likely to believe that prayer would assist conventional medical treatments. Although not statistically significant, we discussed the length of stay (LOS) after surgery and the incidence of sternal wound infection.

    Cardiac resynchronization therapy (CRT) is an established treatment option for symptomatic chronic heart failure (CHF) patients with pharmacological baseline therapy, but not all patients benefit from device therapy. One reason for this may be inadequate device settings. In real-world practice, echocardiographic evaluation of atrioventricular (AV) delay is not performed in a high proportion of patients, as the effect of electrical optimization of CRT is an issue open for investigation. We performed a retrospective observational study analysing the effect of AV-interval evaluation with echocardiography on long-term [32 (23?43) months] clinical outcome in 205 CHF patients. A stepwise Cox regression model including a co-morbidity score, failed AV-interval evaluation, satisfactory device function after the first implantation attempt, failure to reach 100% of the recommended renin-angiotensin system inhibitor and beta-blocker dose at follow-up and CRT device implantation compared with CRT in combination with an implanted cardioverter defibrillator (ICD) was applied. In the total study cohort, 124 (60.5%) patients had reached the primary combined endpoint death or cardiac hospitalization and 59 (28.8%) had died. Cox regression analysis revealed that failed AV-interval evaluation [HR = 1.72 (1.19-2.49), P = 0.004] non-optimized CHF pharmacotherapy dosages [HR = 2.12 (1.32-3.42), P = 0.002], the presence of a CRT/ICD combination device [HR = 1.87 (1.28-2.71), P = 0.001] and satisfactory device function after the first implantation attempt [HR = 0.44 (0.25-0.77), P = 0.004] were associated with the primary endpoint. Echocardiographic evaluation of the AV-interval in patients with CRT was independently associated with improved clinical outcome, impacting on daily clinical practice of HF patient care.

    Since only 60-70% of select patients with chronic heart failure (CHF) are responders in cardiac resynchronization therapy (CRT), this study aimed to investigate whether serum cystatin C (Cys C) can be used to evaluate the effectiveness of CRT in patients with CHF. Seventy-six patients implanted with CRT were retrospectively enrolled. The concentration of serum Cys C was detected and echocardiography was performed before and after 15 days, 1 month, and 6 months of CRT. There were 52 patients (68.4%) who responded to CRT during the follow-up. In the responding group, compared with the pre-CRT, the cardiac function, QRS interval, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF) were significantly improved at 6 months after implantation (P < 0.05), but the level of serum Cys C decreased significantly from 1 month after CRT. There was no change of all the parameters in the non-responding group during the follow-up. In the responding group, the ΔCys C% is significantly related to the ΔLVEDV%, ΔLVESV%, and ΔLVEF%. Multivariate linear analysis shows that the ΔCys C% is significantly related to the ΔLVEDV%. The level of serum Cys C before CRT implantation could predict the response to CRT (AUC = 0.78, P < 0.05). Univariate analysis and multivariate analysis demonstrated that the level of Cys C remained independent predictor for CRT (P = 0.028, 95% CI 0.919-1.348). The level of serum Cys C before CRT implantation is valuable in predicting the response to CRT.

    Traumatic arrests have historically had poor survival rates. Identifying salvageable patients and ideal management is challenging. We aimed to (1) describe the management and outcomes of prehospital traumatic arrests; (2) determine regional variation in survival; and (3) identify Advanced Life Support (ALS) procedures associated with survival. This was a secondary analysis of cases from the Resuscitation Outcomes Consortium Epistry-Trauma and Prospective Observational Prehospital and Hospital Registry for Trauma (PROPHET) registries. Patients were included if they had a blunt or penetrating injury and received cardiopulmonary resuscitation. Logistic regression analyses were used to determine the association between ALS procedures and survival. We included 2,300 patients who were predominately young (Epistry mean [SD], 39 [20] years; PROPHET mean [SD], 40 [19] years), males (79%), injured by blunt trauma (Epistry, 68%; PROPHET, 67%), and treated by ALS paramedics (Epistry, 93%; PROPHET, 98%). A total of 145 patients (6.3%) survived to hospital discharge. More patients with blunt (Epistry, 8.3%; PROPHET, 6.5%) vs. penetrating injuries (Epistry, 4.6%; PROPHET, 2.7%) survived. Most survivors (81%) had vitals on emergency medical services arrival. Rates of survival varied significantly between the 12 study sites (p = 0.048) in the Epistry but not PROPHET (p = 0.14) registries.Patients in the PROPHET registry who received a supraglottic airway insertion or intubation experienced decreased odds of survival (adjusted OR, 0.27; 95% confidence interval, 0.08-0.93; and 0.37; 95% confidence interval, 0.17-0.78, respectively) compared to those receiving bag-mask ventilation. No other procedures were associated with survival. Survival from traumatic arrest may be higher than expected, particularly in blunt trauma and patients with vitals on emergency medical services arrival. Although limited by confounding and statistical power, no ALS procedures were associated with increased

    Introduction Maternal obesity is associated with an increased risk for adverse perinatal outcomes. Obesity is also associated with a chronic inflammatory state and metabolic derangements that affect the newborn. The additional use of cardiopulmonary bypass during the neonatal period could impact the systemic inflammatory response in the immediate postoperative period that manifests as cardiac depression and multi-organ dysfunction. This study aimed to determine the association of maternal obesity and excessive weight gain during pregnancy with the immediate postoperative morbidity of neonatal patients undergoing cardiopulmonary bypass. A retrospective review of neonates who underwent cardiopulmonary bypass within the first 30 days of life at our institution between 2011 and 2013 was conducted. Postoperative variables investigated included the duration of length of mechanical ventilation, length of stay in the ICU, peak vasoactive inotrope scores, and peak lactate level. Maternal obesity was defined as 1st trimester body mass index ⩾30 kg/m2. Excessive weight gain was defined as ⩾12 kg gained during pregnancy. In order to determine the association between maternal obesity or excessive weight gain and postoperative variables, we used multiple linear regression, adjusting for birth weight and risk adjustment for congenital heart surgery score. Records from 58 mother-baby dyads were examined. After controlling for birth weight and risk adjustment for congenital heart surgery score, there were no significant associations between maternal obesity and excessive weight gain during pregnancy versus all postoperative outcomes measured. Despite the known negative impact of maternal obesity on perinatal outcomes, we were unable to find associations between maternal obesity and excessive weight gain during pregnancy versus postoperative outcomes.

    Out-of-hospital cardiac arrest (OHCA) is a major cause of death and morbidity in the United States. Quality cardiopulmonary resuscitation (CPR) has proven to be a key factor in improving survival. The aim of our study was to investigate the outcomes of OHCA when mechanical CPR (LUCAS 2 Chest Compression System™) was utilized compared to conventional CPR. Although controlled trials have not demonstrated a survival benefit to the routine use of mechanical CPR devices, there continues to be an interest for their use in OHCA. We conducted a retrospective observational study of OHCA comparing the outcomes of mechanical and manual chest compressions in a fire department based EMS system serving a population of 1.4 million residents. Mechanical CPR devices were geographically distributed on 11 of 33 paramedic ambulances. Data were collected over a 36-month period and outcomes were dichotomized based on utilization of mechanical CPR. The primary outcome measure was survival to hospital discharge with a cerebral performance category (CPC) score of 1 or 2. This series had 3,469 OHCA reports, of which 2,999 had outcome data and met the inclusion criteria. Of these 2,236 received only manual CPR and 763 utilized a mechanical CPR device during the resuscitation. Return of spontaneous circulation (ROSC) was attained in 44% (334/763) of the mechanical CPR resuscitations and in 46% (1,020/2,236) of the standard manual CPR resuscitations (p = 0.32). Survival to hospital discharge was observed in 7% (52/763) of the mechanical CPR resuscitations and 9% (191/2,236) of the manual CPR group (p = 0.13). Discharge with a CPC score of 1 or 2 was observed in 4% (29/763) of the mechanical CPR resuscitation group and 6% (129/2,236) of the manual CPR group (p = 0.036). In our study, use of the mechanical CPR device was associated with a poor neurologic outcome at hospital discharge. However, this difference was no longer evident after logistic regression adjusting for confounding variables

    Prognostication in out-of-hospital cardiac arrest (OHCA) survivors is often difficult. Recent studies have shown the predictive ability of bispectral index (BIS) monitoring to assist with early neuroprognostication. The aim of this study was to investigate whether characteristics of BIS values equal to zero (BIS 0) (i.e. duration and/or uni- versus bilateral presence) instead of simply their occurrence are better indicators for poor neurological outcome after OHCA by aiming at a specificity of 100%. Between 2011 and 2015, all successfully resuscitated OHCA patients were treated with targeted temperature management (TTM) at 33 °C for 24 hours followed by rewarming over 12 hours (0.3 °C/h). In total, BIS values were registered in 77 OHCA patients. The occurrence of unilateral (BIS 0 at one hemisphere) and bilateral (BIS 0 at both hemispheres) BIS 0 values as well as their total duration were calculated. Receiver operating characteristic (ROC) curves were constructed using the total duration with BIS 0 values calculated from the initiation of TTM onwards to determine poor neurological outcome. In 30 of 77 OHCA patients (39%), at least one BIS 0 value occurred during the first 48 hours after admission. Of these 30 patients, six (20%) had a good (cerebral performance category (CPC) 1-2) and 24 (80%) a poor neurological outcome (CPC3-5) at 180 days post-CA. Within these 30 patients, the incidence of bilateral BIS 0 values was higher in patients with poor neurological outcome (CPC1-2: 2 (33%) vs. CPC3-5: 19 (79%); p = 0.028). The presence of a BIS 0 value predicted poor neurological outcome with a sensitivity of 62% and specificity of 84% (AUC: 0.729; p = 0.001). With a ROC analysis, a total duration of 30,3 minutes with BIS 0 values calculated over the first 48 hours predicted poor neurological outcome with a sensitivity of 63% and specificity of 100% (AUC: 0.861; p = 0.007). This study shows that a prolonged duration with (bilateral) BIS 0 values

    Full Text Available Abstract Background Refusal of heterogenic blood products can be for religious reasons as in Jehovah's Witnesses or otherwise or as requested by an increasing number of patients. Furthermore blood reserves are under continuous demand with increasing costs. Therefore, transfusion avoidance strategies are desirable. We describe a historic comparison and current results of blood saving protocols in Jehovah's Witnesses patients. Methods Data on 250 Jehovah's Witness patients operated upon between 1991 and 2003 (group A were reviewed and compared with a second population of 250 patients treated from 2003 to 2012 (group B. Results In group A, mean age was 51 years of age compared to 68 years in group B. An iterative procedure was performed in 13% of patients in group B. Thirty days mortality was 3% in group A and 1% in group B despite greater operative risk factors, with more redo, and lower ejection fraction in group B. Several factors contributed to the low morbidity-mortality in group B, namely: preoperative erythropoietin to attain a minimal hemoglobin value of 14 g/dl, warm blood cardioplegia, the implementation of the Cornell University protocol and fast track extubation. Conclusions Cardiac surgery without transfusion in high-risk patients such as Jehovah Witnesses can be carried out with results equivalent to those of low risk patients. Recent advances in surgical techniques and blood conservation protocols are main contributing factors.

    A proportion of patients who receive cardiac resynchronization therapy with defibrillator (CRT-D) live to receive a second generator. Controversy exists on whether an implantable cardioverter-defibrillator (ICD) should be offered to patients who have normalized or near-normalized left ventricular ejection fraction (LVEF) at the time of generator replacement (GR). The purpose of this study was to evaluate incidence of appropriate ICD therapy after CRT-D GR. This series involved 1026 consecutive patients who underwent CRT-D implant between January 1, 2002 and December 31, 2012. Echocardiography was assessed before the initial device implant and before GR. ICDs were monitored at our device clinic in person or remotely, or both. Of the cohort, 227 patients (22.1%) underwent CRT-D GR at our institution. Approximately 48% of the patients who received new CRT-D generators were no longer meeting the guidelines indication for ICD use at the time of GR. These patients received subsequent appropriate ICD therapies at a significantly lower rate than those with LVEF generator after GR. Improvement in LVEF after CRT-D GR is associated with significantly reduced incidence of appropriate ICD therapy. Ventricular arrhythmia is less likely to develop with normalized LVEF in nonischemic cardiomyopathy. Copyright © 2017 Heart Rhythm Society. Published by Elsevier Inc. All rights reserved.

    Dysglycemia and glycemic variability are associated with poor outcomes in critically ill patients. Targeted temperature management alters blood glucose homeostasis. We investigated the association between blood glucose concentrations and glycemic variability and the neurologic outcomes of patients randomized to targeted temperature management at 33°C or 36°C after cardiac arrest. Post hoc analysis of the multicenter TTM-trial. Primary outcome of this analysis was neurologic outcome after 6 months, referred to as "Cerebral Performance Category." Thirty-six sites in Europe and Australia. All 939 patients with out-of-hospital cardiac arrest of presumed cardiac cause that had been included in the TTM-trial. Targeted temperature management at 33°C or 36°C. Nonparametric tests as well as multiple logistic regression and mixed effects logistic regression models were used. Median glucose concentrations on hospital admission differed significantly between Cerebral Performance Category outcomes (p variability, were associated with poor neurologic outcome and death. More patients in the 33°C treatment arm had hyperglycemia.

    To determine whether or not there was a significant difference between the methods of centrifugation (CF) and multiple-pass hemoconcentration (MPH) of the residual cardiopulmonary-bypass volume in relation to biochemical measurements and patient outcomes. Prospective, randomized, and controlled. Conducted at a western Canadian tertiary care hospital. Consisted of 61 consecutive male and female patients from ages 40 to 80 who were scheduled for cardiac surgery with cardiopulmonary bypass. Either the centrifugation or multiple-pass hemoconcentration method was used to process the residual blood from the cardiopulmonary bypass circuit. The 12-hour postoperative levels of serum hemoglobin were not significantly different in the centrifugation group as compared to the multiple-pass hemoconcentration group. However, the serum levels of total protein and albumin were significantly higher in the multiple-pass hemoconcentration group as compared to the centrifugation group. Additionally, after 12-hours postoperatively, the serum fibrinogen and platelet counts were significantly higher in the multiple-pass hemoconcentration group as compared to those of the centrifugation group. The allogeneic product transfusion index and the chest-tube blood drainage indices were lower in the multiple-pass hemoconcentration group as compared to the centrifugation group. Although the CF method provided a product in a shorter turnaround time, with consistent clearance of heparin, the MPH method trended towards enhanced biochemical and clinical patient outcomes over the 12-hour postoperative period.

    Management of acute type A aortic dissection (AAAD) is challenging and operative strategies are varied. We used the STS Adult Cardiac Surgery Database (STS ACSD) to describe contemporary surgical strategies and outcomes for AAAD. Between July 2011 and September 2012, 2982 patients with AAAD underwent operations at 640 centers in North America. In this cohort, median age was 60 years old, 66% were male, and 80% had hypertension. The most common arterial cannulation strategies included femoral (36%), axillary (27%), and direct aortic (19%). The median perfusion and cross-clamp times were 181 and 102 min, respectively. The lowest temperature on bypass showed significant variation. Hypothermic circulatory arrest (HCA) was used in 78% of cases. Among those undergoing HCA, brain protection strategies included antegrade cerebral perfusion (31%), retrograde cerebral perfusion (25%), both (4%), and none (40%). Median HCA plus cerebral perfusion time was 40 min. Major complications included prolonged ventilation (53%), reoperation (19%), renal failure (18%), permanent stroke (11%), and paralysis (3%). Operative mortality was 17%. The median intensive care unit and hospital length of stays were 4.7 and 9.0 days, respectively. Among 640 centers, the median number of cases performed during the study period was three. Resuscitation, unresponsive state, cardiogenic shock, inotrope use, age >70, diabetes, and female sex were found to be independent predictors of mortality. These data describe contemporary patient characteristics, operative strategies, and outcomes for AAAD in North America. Mortality and morbidity for AAAD remain high. © 2018 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Refractory post-cardiotomy cardiogenic shock (PCCS is a relatively rare phenomenon that can lead to rapid multi-organ dysfunction syndrome and is almost invariably fatal without advanced mechanical circulatory support (AMCS, namely extra-corporeal membrane oxygenation (ECMO or ventricular assist devices (VAD. In this multicentre observational study we retrospectively analyzed the outcomes of salvage venoarterial ECMO (VA ECMO and VAD for refractory PCCS in the 3 adult cardiothoracic surgery centres in Scotland over a 20-year period. Methods The data was obtained through the Edinburgh, Glasgow and Aberdeen cardiac surgery databases. Our inclusion criteria included any adult patient from April 1995 to April 2015 who had received salvage VA ECMO or VAD for PCCS refractory to intra-aortic balloon pump (IABP and maximal inotropic support following adult cardiac surgery. Results A total of 27 patients met the inclusion criteria. Age range was 34–83 years (median 51 years. There was a large male predominance (n = 23, 85 %. Overall 23 patients (85 % received VA ECMO of which 14 (61 % had central ECMO and 9 (39 % had peripheral ECMO. Four patients (15 % were treated with short-term VAD (BiVAD = 1, RVAD = 1 and LVAD = 2. The most common procedure-related complication was major haemorrhage (n = 10. Renal failure requiring renal replacement therapy (n = 7, fatal stroke (n = 5, septic shock (n = 2, and a pseudo-aneurysm at the femoral artery cannulation site (n = 1 were also observed. Overall survival to hospital discharge was 40.7 %. All survivors were NYHA class I-II at 12 months’ follow-up. Conclusion AMCS for refractory PCCS carries a survival benefit and achieves acceptable functional recovery despite a significant complication rate.

    Prospective collected data of the TraumaRegister DGU(®) were analyzed to derive survival rates and predictors for non-survival in the children who had suffered traumatic cardiorespiratory arrest. Different time points of resuscitation efforts (only preclinical, in the emergency room (ER) or preclinical+ER) were analyzed in terms of mortality and neurological outcome. The database of the TraumaRegister DGU(®) comprising 122,742 patients from 1993 to 2013 was analyzed. The main focus of this survey was on the paediatric group defined by an age ≤ 14 years who could be compared to adults. Different statistical analysis (univariate and multivariate analysis, logistic regression) were performed with mortality as the target variable. Differences between the paedatric group and adults were analysed by Fisher's exact test. Data after preclinical and/or ER resuscitation from 152 children and 1690 adults were analyzed. A good or moderate outcome (GOS 5+4) was found in 19.4% of the children's group compared to 12.4% of the adults (p=0.02). Analysis of the GOS 5+4 subgroups after preclinical resuscitation only revealed that these outcomes were achieved by 19.4% of the paediatric group and 13.2% of the adults (p=0.24), after ER-only resuscitation by 37.0% of the children and 19.6% of the adults (p=0.046), and after preclinical and ER resuscitation by only 10.9% of the children compared to 2.5% of the adults (p=0.006). Taking only survivors into account, 84.8% of the children and 62% of the adults had a GOS 4+5. The highest risk for mortality in the logistic regression model was associated with preclinical intubation, followed by GCS 3, blood transfusion and severe head injury with AIS ≥3 and ISS. CPR in children after severe trauma seems to yield a better outcome than in adults, and appears to be more justified than the current guidelines would imply. Resuscitation in the ER is associated with better neurological outcomes compared with resuscitation in a preclinical

    Methods: We measured serum albumin concentration prospectively in 300 children with congenital heart disease who underwent surgery between July and September 2008 in Shaheed Rajaee hospital. Serum albumin concentration was measured before and 48 hours after cardiac surgery and was subsequently compared between 2 groups: cyanotic and acyanotic and also with normal values. Results: Serum albumin concentration decreased on the second post-operative day in 70 (23.3% patients. There was a positive correlation between the post-surgical hypoalbuminemia and cyanotic heart disease. The cyanotic children had lower serum albumin concentration than the acyanotic ones (P value <0.001. There was a significant association between post-operative serum albumin concentration and acute renal failure (P value <0.001 and death (P value <0.001. Drop in serum albumin concentration was more prominent in the males than in the females (P value=0.038 and in the cyanotic patients than in the acyanotic ones (P value <0.001 as well as in those with acute renal failure (P value <0.001, pericardial effusion (P value =0.050, seizure (P value <0.001, and death (P value <0.001. Hypoalbuminemia was not associated with longer hospital (P value=0.142 or intensive care unit stay (P value=0.199 . Conclusion: Post-operative serum albumin concentration was lower in the cyanotic children and male patients in our study. In addition, the post-operative decrease in albumin was associated with an increased risk of pericardial effusion, renal failure, seizure, and death.

    Individuals with schizophrenia face significant challenges in daily functioning, and although social cognition predicts how well patients respond to these challenges, associated physiological mechanisms remain unspecified. The present study draws from polyvagal theory and tested the hypothesis that respiratory sinus arrhythmia (RSA), an established indicator of the capacity to self-regulate and adapt to environmental demands, combines with social cognition to predict functional outcome. Using data from 41 schizophrenia patients and 36 healthy comparison subjects, we replicated group differences in RSA and social cognition and also demonstrated that RSA and social cognition interact to predict how effectively patients manage work and independent living activities. Specifically, RSA did not enhance functional outcomes when social cognition was already strong, but higher levels of RSA enabled effective role functioning when social-cognitive performance was impaired. Jointly, RSA and social cognition accounted for 40% of the variance in outcome success, compared with 21% when evaluating social cognition alone. As polyvagal theory suggests, physiological flexibility and self-regulatory capacity may compensate for poorer social-cognitive skills among schizophrenia patients.

    Full Text Available ObjectivesClinical trials of either pulmonary perfusion or ventilation during cardiopulmonary bypass are equivocal. We hypothesized that to achieve significant improvement in outcomes both interventions had to be concurrent.DesignRetrospective case-control studySettingsMajor academic tertiary referral medical centerParticipants274 consecutive patients who underwent open heart surgery with cardiopulmonary bypass 2009 - 2013.InterventionsThe outcomes of 86 patients who received pulmonary perfusion and ventilation during cardiopulmonary bypass were retrospectively compared to the control group of 188 patients.Measurements and Main ResultsRespiratory complications rates were similar in both groups (33.7% vs. 33.5%, as were the rates of postoperative pneumonia (4.7% vs. 4.3%, pleural effusions (13.9% vs. 12.2% and re-intubations (9.3% vs. 9.1%. Rates of adverse postoperative cardiac events including ventricular tachycardia (9.3% vs. 8.5% and atrial fibrillation (33.7% vs. 28.2% were equivalent in both groups. Incidence of sepsis (8.1% vs. 5.3%, postoperative stroke (2.3% vs. 2.1%, acute kidney injury (2.3% vs. 3.7% and renal failure (5.8% vs. 3.7% were likewise comparable. Despite similar transfusion requirements, coagulopathy (12.8% vs. 5.3%, p=0.031 and the need for mediastinal re-exploration (17.4% vs. 9.6%, p=0.0633 were observed more frequently in the pulmonary perfusion and ventilation group, but the difference did not reach the statistical significance. ICU and hospital stays, and the ICU readmission rates (7.0% vs. 8.0% were similar in both groups.ConclusionsSimultaneous pulmonary perfusion and ventilation during cardiopulmonary bypass were not associated with improved clinical outcomes.

    Little is known about the influence of comprehensive public health initiatives according to out-of-hospital cardiac arrest (OHCA) location, particularly at home, where resuscitation efforts and outcomes have historically been poor. To describe temporal trends in bystander cardiopulmonary resuscitation (CPR) and first-responder defibrillation for OHCAs stratified by home vs public location and their association with survival and neurological outcomes. This observational study reviewed 8269 patients with OHCAs (5602 [67.7%] at home and 2667 [32.3%] in public) for whom resuscitation was attempted using data from the Cardiac Arrest Registry to Enhance Survival (CARES) from January 1, 2010, through December 31, 2014. The setting was 16 counties in North Carolina. Patients were stratified by home vs public OHCA. Public health initiatives to improve bystander and first-responder interventions included training members of the general population in CPR and in the use of automated external defibrillators, teaching first responders about team-based CPR (eg, automated external defibrillator use and high-performance CPR), and instructing dispatch centers on recognition of cardiac arrest. Association of resuscitation efforts with survival and neurological outcomes from 2010 through 2014. Among home OHCA patients (n = 5602), the median age was 64 years, and 62.2% were male; among public OHCA patients (n = 2667), the median age was 68 years, and 61.5% were male. After comprehensive public health initiatives, the proportion of patients receiving bystander CPR increased at home (from 28.3% [275 of 973] to 41.3% [498 of 1206], P public (from 61.0% [275 of 451] to 70.5% [424 of 601], P = .01), while first-responder defibrillation increased at home (from 42.2% [132 of 313] to 50.8% [212 of 417], P = .02) but not significantly in public (from 33.1% [58 of 175] to 37.8% [93 of 246], P = .17). Survival to discharge improved for arrests at home (from 5.7% [60 of 1057

    Renal dysfunction is often associated with chronic heart failure, leading to increased morbi-mortality. However, data regarding these patients after cardiac resynchronization therapy (CRT) is sparse. We sought to evaluate response and long-term mortality in patients with heart failure and renal dysfunction and assess renal improvement after CRT. We analyzed 178 consecutive patients who underwent successful CRT device implantation (age 64 ± 11 years; 69% male; 92% in New York Heart Association (NYHA) functional class ≥ III; 34% with ischemic cardiomyopathy). Echocardiographic response was defined as ≥ 15% reduction in left ventricular end-systolic diameter and clinical response as a sustained improvement of at least one NYHA functional class. Renal dysfunction was defined as an estimated glomerular filtration rate (eGFR) below 60 mL/min/1.73 m 2 . Renal dysfunction was present in 34.7%. Renal dysfunction was not an independent predictor of echocardiographic response (OR 1.109, 95% CI 0.713-1.725, p 0.646) nor clinical response (OR 1.003; 95% CI 0.997-1.010; p 0.324). During follow-up (mean 55.2 ± 32 months), patients with eGFR < 60mL/min/1.73 m 2 had higher overall mortality (HR 4.902, 95% CI 1.118-21.482, p 0.035). However, clinical response in patients with renal dysfunction was independently associated with better long-term survival (HR 0.236, 95% CI 0.073-0.767, p 0.016). Renal function was significantly improved in patients who respond to CRT (ΔeGFR + 5.5 mL/min/1.73 m 2 at baseline vs. follow-up, p 0.049), while this was not evident in nonresponders. Improvements in eGFR of at least 10 mL/min/1.73 m 2 were associated with improved survival in renal dysfunction patients (log-rank p 0.036). Renal dysfunction was associated with higher long-term mortality in CRT patients, though, it did not influence echocardiographic nor functional response. Despite worse overall prognosis, renal dysfunction patients who are responders showed long-term survival benefit

    This study evaluated whether dobutamine gated blood pool scintigraphy can predict improvement of cardiac sympathetic nerve activity and cardiac function. Sixteen patients (10 men and 6 women, mean age 59{+-}13 years) with dilated cardiomyopathy underwent dobutamine gated blood pool scintigraphy to measure left ventricular ejection fraction (LVEF) using tracer at 0, 5, 10 and 15 {mu}g/kg/min before treatment. Patients were divided into good responders (LVEF increase {>=}15%) 8 patients (GR Group) and poor responders (LVEF increase <15%) 8 patients (PR Group) after treatment with {beta}-blocker or amiodarone with a background treatment of digitalis, diuretics and angiotensin converting enzyme inhibitor. I-123 metaiodobenzylguanidine (MIBG) imaging to evaluate cardiac sympathetic nerve activity and echocardiography were performed before and at one year after treatment. MIBG imaging was obtained 4 hours after tracer injection, and the heart/mediastinum count ratio (H/M ratio) calculated from the anterior planar image and the total defect score (TDS) from the single photon emission computed tomography image. LVEF and left ventricular endo-diastolic dimension (LVDd) were measured by echocardiography and New York Heart Association (NYHA) functional class was evaluated. The GR Group showed TDS decreased from 28{+-}6 to 17{+-}12 (p<0.05), H/M ratio increased from 1.79{+-}0.26 to 2.07{+-}0.32 (p<0.05), LVEF increased from 29{+-}8% to 48{+-}10% (p<0.01), and LVDd decreased from 65{+-}4 mm to 58{+-}5 mm (p<0.05). In contrast, the PR group showed no significant changes in TDS. H/M ratio, LVEF and LVDd. NYHA functional class improved in both groups. The improvement was better in the GR Group than in the PR group. Dobutamine gated blood pool scintigraphy is useful to predict the improvement of the cardiac sympathetic nerve activity and cardiac function, and symptoms after treatment in patients with dilated cardiomyopathy.

    This research is to study if quick administration of adrenaline on OHCA prior to hospitalization has an effect on improving CPC1-2 at one month. A total 13,326 cases were extracted from 2011 to 2014 Utstein data for this retrospective cohort study, also, EMT reached the patients within 16min after 119 called and adrenaline was then administered within 22min of after contact. Patients were contacted within 8min of the 119 call (n=6956), and were contacted between 8 and 16min after the call (n=6370). Further divided into groups in which the adrenaline was administered within/without 10min after contact. Primary outcome was the rate of a good prognosis for cerebral performance (CPC1-2) at 1 month and secondary outcome was the return of spontaneous circulation (ROSC) rate. The odds ratio of the CPC1-2 at 1month by the EMS reached within 8min after 119 call and then adrenaline administered within 10min was 2.12 (1.54-2.92).Those reached between 8 and 16min was 2.66 (1.97-3.59). However, the ROSC rate was 2.00 (1.79-2.25) for those reached within 8min and also 2.00 (1.79-2.25) for those reached between 8min and 16min. In cases of OHCA, it appears that the CPC1-2 rate after 1month can be improved even in cases where the victim is reached >8min after the 119 call, as long as the victim is reached within 16min and emergency responders administer the adrenaline as quickly as possible.

    To review treatment and outcomes of septic shock in patients with pulmonary hypertension (PH) managed at a tertiary care institution. We identified consecutive patients with non-cardiac PH (non-Group 2 in the World Health Organization classification) who were treated for septic shock in four intensive care units at a tertiary care institution between July 2004 and July 2007. Patients with a left ventricular ejection fraction patients. The major causes of PH were chronic obstructive pulmonary disease, interstitial lung disease and portopulmonary hypertension. PH was mild in 46 patients (56%), moderate in 21 (26%) and severe in 15 (18%). Vasopressor treatment was initiated in 69 patients (84%) within the first 48 hours: noradrenaline was most commonly used (53 patients, 65%), and 51 patients (62%) were treated with more than one agent. Sixty-seven patients (82%) were mechanically ventilated, and 33 (40%) required renal replacement therapy. Fortythree patients (52%) survived to hospital discharge; 23 (28%) remained alive at 1 year. Hospital mortality increased with severity of PH: 28% in mild, 67% in moderate and 80% in severe PH. Nonsurvivors were more likely to have plateau pressures beyond 30 cm H(2)O while mechanically ventilated within the first 48 hours in the ICU (56% v 29%, P = 0.03), to develop atrial fibrillation (AF) (46% v 12%, P patients with PH who developed severe sepsis and septic shock.

  20. Cardiac Rehabilitation for Patients With Coronary Artery Disease: A Practical Guide to Enhance Patient Outcomes Through Continuity of Care

    Full Text Available Coronary artery disease (CAD is a leading cause of disease burden worldwide. Referral to cardiac rehabilitation (CR is a class I recommendation for all patients with CAD based on findings that participation can reduce cardiovascular and all-cause mortality, as well as improve functional capacity and quality of life. However, programme uptake remains low, systematic progression through the traditional CR phases is often lacking, and communication between health care providers is frequently suboptimal, resulting in fragmented care. Only 30% to 50% of eligible patients are typically referred to outpatient CR and fewer still complete the programme. In contemporary models of CR, patients are no longer treated by a single practitioner, but rather by an array of health professionals, across multiples specialities and health care settings. The risk of fragmented care in CR may be great, and a concerted approach is required to achieve continuity and optimise patient outcomes. ‘Continuity of care’ has been described as the delivery of services in a coherent, logical, and timely fashion and which entails 3 specific domains: informational, management, and relational continuity. This is examined in the context of CR.

    Non-medicine-assisted tracheal intubation in prehospital trauma is associated with a dismal prognosis. We wished to study the outcome of medical patients who underwent non-medicine-assisted tracheal intubation. This retrospective study of patients attending our university hospital emergency department was conducted over seven years. The tracheal intubation database was analysed to identify medical patients not in cardiac arrest undergoing tracheal intubation without medicines. Intensive care unit, hospital, 12-month mortality and patients' residence at 12 months were recorded. Eighty patients were identified who met inclusion criteria. The most common reason for intubation was definite airway compromise due to decreased conscious level (62.5%), then respiratory failure (26.3%) and finally potentially compromised airway due to a decreased conscious level (11.2%). Eighty-eight percent of patients with a definitely compromised airway were successfully intubated at first attempt compared with 66.7% of patients with a potentially compromised airway or respiratory failure (P= 0.03). Of 75 patients with complete data, 30 (40%) were survivors at 12 months, with all but two (6.7%) living at home. Non-medicine-assisted laryngoscopy leads to an increased first time tracheal intubation failure rate in patients with intact airway reflexes and, therefore, cannot be recommended as best practice.

    Heart rate (HR) parameters are known indicators of cardiovascular complications after cardiac surgery, but there is little evidence of their role in predicting outcome after major vascular surgery. The purpose of this study was to determine whether arrival HR (AHR) and highest intraoperative HR are associated with mortality or major adverse cardiac events (MACEs) after elective vascular surgery in the Vascular Quality Initiative (VQI). Patients undergoing elective lower extremity bypass (LEB), aortofemoral bypass (AFB), and open abdominal aortic aneurysm (AAA) repair in the VQI were analyzed. MACE was defined as any postoperative myocardial infarction, dysrhythmia, or congestive heart failure. Controlled HR was defined as AHR HR (DHR) was defined as highest intraoperative HR - AHR. Procedure-specific MACE models were derived for risk stratification, and generalized estimating equations were used to account for clustering of center effects. HR, beta-blocker exposure, cardiac risk, and their interactions were explored to determine association with MACE or 30-day mortality. A Bonferroni correction with P HR associations disappeared in controlling for beta-blocker status. For AFB and open AAA repair patients, there was no significant association between AHR and MACE or 30-day mortality, irrespective or cardiac risk or beta-blocker status. DHR and extremes of highest intraoperative HR (>90 or 100 beats/min) were analyzed among all three operations, and no consistent associations with MACE or 30-day mortality were detected. The VQI AHR and highest intraoperative HR variables are highly confounded by patient presentation, operative variables, and beta-blocker therapy. The discordance between cardiac risk and HR as well as the lack of consistent correlation to outcome makes them unreliable predictors. The VQI has elected to discontinue collecting AHR and highest intraoperative HR data, given insufficient evidence to suggest their importance as an outcome measure. Copyright

    Clinical evidence supports lower morbidity with off-pump coronary revascularization surgery as well as superior short- and mid-term outcomes, equivalent graft patency, and reduced cost. The purpose of this study was to compare cardiac rehabilitation (CR) outcomes between patients undergoing on-pump versus off-pump coronary artery bypass surgery. Data were retrospectively examined for patients who participated in CR between 1996 and 2004. Two hundred ninety-five patients who underwent bypass surgery and completed at least 80% of their 36 required sessions were divided into on-pump and off-pump groups. Pre- and post-CR measures included grip strength, flexibility, energy expended during class, quality of life, and self-efficacy. Both groups were similar with respect to age, sex, ejection fraction, and mean number of grafts. There were no statistical differences between the on-pump and off-pump groups (P > .05) for weight, abdominal and hip circumferences, grip strength, flexibility, and total energy expenditure. In addition, there were no between-group differences regarding quality of life and self-efficacy. Grip strength, flexibility, and energy expenditure during class improved with CR regardless of the surgical procedure (P = .001). Quality of life (P = .001) and self-efficacy (P = .001) also improved. The present data support the concept that although there are clinical advantages to off-pump surgery, there is no benefit over on-pump surgery regarding CR. Subsequently, patients undergoing off-pump surgery should be managed similarly as their on-pump counterparts.

    Ischemic postconditioning (PC) using three intentional pauses at the start of cardiopulmonary resuscitation (CPR) improves outcomes after cardiac arrest in pigs when epinephrine (epi) is used before defibrillation. We hypothesized PC, performed during basic life support (BLS) in the absence of epinephrine, would reduce reperfusion injury and enhance 24h functional recovery. Prospective animal investigation. Animal laboratory Female farm pigs (n=46, 39±1kg). Protocol A: After 12min of ventricular fibrillation (VF), 28 pigs were randomized to four groups: (A) Standard CPR (SCPR), (B) active compression-decompression CPR with an impedance threshold device (ACD-ITD), (C) SCPR+PC (SCPR+PC) and (D) ACD-ITD CPR+PC. Protocol B: After 15min of VF, 18 pigs were randomized to ACD-ITD CPR or ACD-ITD+PC. The BLS duration was 2.75min in Protocol A and 5min in Protocol B. Following BLS, up to three shocks were delivered. Without return of spontaneous circulation (ROSC), CPR was resumed and epi (0.5mg) and defibrillation delivered. The primary end point was survival without major adverse events. Hemodynamic parameters and left ventricular ejection fraction (LVEF) were also measured. Data are presented as mean±SEM. Protocol A: ACD-ITD+PC (group D) improved coronary perfusion pressure after 3min of BLS versus the three other groups (28±6, 35±7, 23±5 and 47±7 for groups A, B, C, D respectively, p=0.05). There were no significant differences in 24h survival between groups. LVEF 4h post ROSC was significantly higher with ACD-ITD+PC vs ACD-ITD alone (52.5±3% vs. 37.5±6.6%, p=0.045). Survival rates were significantly higher with ACD-ITD+PC vs. ACD-ITD alone (p=0.027). BLS using ACD-ITD+PC reduced post resuscitation cardiac dysfunction and improved functional recovery after prolonged untreated VF in pigs. 12-11. Copyright © 2016 Elsevier Ireland Ltd.

    Full Text Available Aim. The objective of this study was to investigate the influence of OSA on cardiac function in Chinese patients with ST-elevation myocardial infarction (STEMI and determine the prognostic impact of OSA among these patients. Methods. In this retrospective study, 198 STEMI patients were enrolled. Doppler echocardiography was performed to detect the effect of OSA on cardiac function. Major adverse cardiac events (MACE and cardiac mortality were analyzed to determine whether OSA was a clinical prognostic factor; its prognostic impact was then assessed adjusting for other covariates. Results. The echocardiographic results showed that the myocardium of STEMI patients with OSA appeared to be more hypertrophic and with a poorer cardiac function compared with non-OSA STEMI patients. A Kaplan-Meier survival analysis revealed significantly higher cumulative incidence of MACE and cardiac mortality in the OSA group compared with that in the non-OSA group during a mean follow-up of 24 months. Multivariate Cox regression analysis revealed that OSA was an independent risk factor for MACE and cardiac mortality. Conclusion. These results indicate that the OSA is a powerful predictor of decreased survival and exerts negative prognostic impact on cardiac function in STEMI patients.

    Background In an early analysis of this trial, use of a magnetically levitated centrifugal continuous-flow circulatory pump was found to improve clinical outcomes, as compared with a mechanical-bearing axial continuous-flow pump, at 6 months in patients with advanced heart failure. Methods In a randomized noninferiority and superiority trial, we compared the centrifugal-flow pump with the axial-flow pump in patients with advanced heart failure, irrespective of the intended goal of support (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke (with disabling stroke indicated by a modified Rankin score of >3; scores range from 0 to 6, with higher scores indicating more severe disability) or survival free of reoperation to replace or remove a malfunctioning device. The noninferiority margin for the risk difference (centrifugal-flow pump group minus axial-flow pump group) was -10 percentage points. Results Of 366 patients, 190 were assigned to the centrifugal-flow pump group and 176 to the axial-flow pump group. In the intention-to-treat population, the primary end point occurred in 151 patients (79.5%) in the centrifugal-flow pump group, as compared with 106 (60.2%) in the axial-flow pump group (absolute difference, 19.2 percentage points; 95% lower confidence boundary, 9.8 percentage points [Ppump malfunction was less frequent in the centrifugal-flow pump group than in the axial-flow pump group (3 patients [1.6%] vs. 30 patients [17.0%]; hazard ratio, 0.08; 95% CI, 0.03 to 0.27; Ppump group than in the axial-flow pump group (10.1% vs. 19.2%; hazard ratio, 0.47; 95% CI, 0.27 to 0.84, P=0.02). Conclusions In patients with advanced heart failure, a fully magnetically levitated centrifugal-flow pump was superior to a mechanical-bearing axial-flow pump with regard to survival free of disabling stroke or reoperation to replace or remove a malfunctioning device.

    Cardiac resynchronization therapy (CRT) is a treatment for heart failure (HF) that improves cardiac, functional, and quality of life (QoL) outcomes. This study was designed to examine the effect of the addition of CRT (CRTD) to the implantable cardioverter defibrillator (ICD) on psychological functioning. Overall, 99 participants completed batteries before and 9 months after ICD or CRTD implantation in a registry of HF patients receiving device treatment in 3 US centers. Measures included validated indices of mental health (State Trait Anxiety Inventory, Patient Health Questionnaire: Depression) and generic and disease/device-specific QoL (Medical Outcomes Study-Short Form-12, Kansas City Cardiomyopathy Questionnaire, Florida Patient Acceptance Survey, Florida Shock Anxiety Scale). Mixed between-within analyses of covariance were employed to compare device groups on each outcome controlling for cardiac and demographic covariates. Clinically significant anxiety was elevated in both groups at both time points (57% CRTD at baseline, 29% CRTD 9 months, 44% ICD at baseline, 45% ICD 9 months). Clinically significant depressive symptoms were high at baseline (38% CRTD, 31% ICD), but dropped at follow-up (16% CRTD, 7% ICD; P = 0.01). Participants with CRTD had improved mental component and disease-specific QoL following CRT; however, CRTD patients had worse QoL, worse mental component QoL at baseline, and worse device acceptance at 9-month follow-up than patients with ICDs (all P patients being implanted with CRTD in research and clinical work. © 2014 Wiley Periodicals, Inc.

    This study aimed to evaluate the cardiac outcome for children with microdeletion 22q11.2 and congenital heart defect (CHD). A total of 49 consecutive children with 22q11.2 and CHD were retrospectively identified. The CHD consisted of tetralogy of Fallot and variances (n = 22), interrupted aortic arch (n = 10), ventricular septal defect (n = 8), truncus arteriosus (n = 6), and double aortic arch (n = 1). Extracardiac anomalies were present in 46 of 47 children. The median follow-up time was 8.5 years (range, 3 months to 23.5 years). Cardiac surgical repair was performed for 35 children, whereas 5 had palliative surgery, and 9 never underwent cardiac surgery. The median age at repair was 7.5 months (range, 2 days to 5 years). The mean hospital stay was 35 days (range, 7-204 days), and the intensive care unit stay was 15 days (range, 3-194 days). Significant postoperative complications occurred for 26 children (74%), and surgery for extracardiac malformations was required for 21 patients (43%). The overall mortality rate was 22% (11/49), with 1-year survival for 86% and 5-year survival for 80% of the patients. A total of 27 cardiac reinterventions were performed for 16 patients (46%) including 15 reoperations and 12 interventional catheterizations. Residual cardiac findings were present in 25 patients (71%) at the end of the follow-up period. Children with microdeletion 22q11.2 and CHD are at high risk for mortality and morbidity, as determined by both the severity of the cardiac lesions and the extracardiac anomalies associated with the microdeletion.

    To examine changes in functional capacity, anxiety, depression and BMI in patients who completed a cardiac rehabilitation programme and to determine the influencing factors. While the effectiveness of cardiac rehabilitation is long established, more studies are needed to examine the combined effectiveness of this multicomponent intervention and the factors that influence this in the changed profile of patients currently attending cardiac rehabilitation. The study was a longitudinal retrospective study of patients following a six- or eight-week Phase III cardiac rehabilitation programme. The study recruited 154 patients. Functional capacity, anxiety, depression, weight, waist circumference and BMI were assessed at the beginning and end of cardiac rehabilitation. t-tests were used to assess changes over time, and multivariate regression analysis was used to determine the influence of factors on these changes. Significant improvements were seen in functional capacity, waist circumference, weight and BMI, but not in depression and anxiety. Multivariate analysis revealed that being younger and less fit was associated with greater improvements in functional capacity while reason for referral, gender, depression or BMI did not influence improvements in functional capacity. Models testing the influence of the factors on BMI, anxiety and depression were not significant. Cardiac rehabilitation is still an effective method to instigate changes in cardiac risk factors despite the changes in patients profile attending programmes. Continued encouragement of the historically less typical patients to participate in cardiac rehabilitation is needed as reason for referral, gender, depression or BMI did not influence improvements in functional capacity. Despite psychosocial components within the programme, no significant improvements were observed over cardiac rehabilitation in depression or anxiety. While effectiveness was observed, there is room for further optimisation of practice

    Having previously reported that comprehensive cardiac rehabilitation (CCR) is effective for secondary prevention post-transient ischemic attack (TIA)/mild nondisabling stroke (MNDS), we present psychometric findings for the same sample that elucidate subacute TIA/MNDS psychological outcomes and test whether CCR would be independently associated with psychological improvements. In this prospective cohort trial patients with ≥1 risk factor, recruited from a stroke prevention clinic within 12 months (mean = 11.5 weeks) post-TIA/MNDS, entered CCR. Of the 110 recruited patients, 100 (mean age = 65.4 years; 46 females) entered CCR and 80 completed CCR (mean duration = 7.6 months). At CCR entry, 16.5% and 39.2% screened positively for depression and anxiety, decreasing nonsignificantly at exit to 4.2%, and significantly to 16.9% (P = .008), respectively. Age-corrected deficits occurred more frequently than expected (P ≤ .03); at entry, mental health status (13.3%), clock-drawing (31.6%), oral-verbal fluency (16.9%), word-list learning (11.2%), and recall (12.6%); at exit, clock-drawing (30.0%). Entry-to-exit, mean depression, anxiety, mental and physical health status, word-list learning, memory, digit-symbol coding, and oral-verbal fluency scores improved significantly (P ≤ .031). No reliable change indices were significant. Psychological service recipients improved significantly more than nonrecipients in depression (P = .049). Baseline North American Adult Reading Test score predicted exercise attendance (R = 0.275; P = .044); New York Heart Association (NYHA) class and depression score predicted exit physical health status (R = 0.770, P psychological improvements. CCR psychological treatment may benefit depression. Subacute NYHA class and depression may later affect quality of life.

    The purpose of this study was to determine whether, in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI), the reduction in cardiac mortality in those taking bivalirudin compared with unfractionated heparin plus a glycoprotein IIb/IIIa inhibitor (UFH+GPI) can be fully attributed to reduced bleeding. The association between hemorrhagic complications and mortality may explain the survival benefit with bivalirudin. A total of 3,602 STEMI patients undergoing primary PCI were randomized to bivalirudin versus UFH+GPI. Three-year cardiac mortality was analyzed in patients with and without major bleeding. When compared with UFH+GPI, bivalirudin resulted in lower 3-year rates of major bleeding (6.9% vs. 10.5%, hazard ratio [HR]: 0.64 [95% confidence interval (CI): 0.51 to 0.80], p accounting for major bleeding and other adverse events, bivalirudin was still associated with a 43% reduction in 3-year cardiac mortality (adjusted HR: 0.57 [95% CI: 0.39 to 0.83], p = 0.003). Bivalirudin reduces cardiac mortality in patients with STEMI undergoing primary PCI, an effect that can only partly be attributed to prevention of bleeding. Further studies are required to identify the nonhematologic benefits of bivalirudin. (Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction; NCT00433966).

    To explore the prognostic role of free triiodothyronine (FT3) on all-cause mortality and heart failure (HF) hospitalization in patients receiving cardiac resynchronization therapy (CRT). In this single-center retrospective cohort study, a total of 202 chronic heart failure (CHF) patients who had CRT implantation from January 2010 to December 2014 were enrolled. Clinical outcomes were defined as all-cause mortality (including heart transplantation) and new heart failure (HF) hospitalization. Patients were divided into three groups according to FT3 tertiles: FT3≤4.08 pmol/L group (n=67), FT3 4.09-4.71 pmol/L group (n=68) and FT3>4.71 pmol/L group (n=67). Kaplan-Meier analyses were performed for each outcome. Cox proportional-hazards regression analyses were used to evaluate the independent prognosis of FT3 in CRT treated patients. Patients in FT3≤4.08 pmol/L group tended to be older, with more women patients, and had lower estimated glomerular filtration rate (eGFR), hemoglobin and serum sodium concentration. They were also less frequently subjected to smoking, alcohol consumption and were less likely prescribed with renin-angiotensin-aldosterone system inhibitors. Also, this group had highest proportion of NYHA class Ⅳ patients. Kaplan-Meier analyses demonstrated that FT3 4.09-4.71 pmol/L group was associated with a significantly better survival (P=0.022) and less new hospitalizations for HF event (P=0.020). Cox regression analyses indicated that FT3 4.09-4.71 pmol/L was an independent protective factor for both all-cause mortality (HR=0.220, 95%CI: 0.069-0.700, P=0.011) and HF hospitalization (HR=0.490, 95%CI: 0.241-0.996, P=0.049). Left ventricular end diastolic diameter (LVEDd) enlargement was an independent risk factor of all-cause mortality(HR=1.043, 95%CI: 1.004-1.083, P=0.031). Patients in FT3 4.09-4.71 pmol/L group had the lowest risk of all-cause mortality and HF hospitalization after CRT implantation.

    Full Text Available Abstract Background Patterns of care for acute myocardial infarction (AMI strongly depend on the availability of on-site cardiac catheterization facilities. Although the management found at hospitals without on-site catheterization does not lead to increased mortality, little it known about its impact on resource utilization and non-fatal outcomes. Methods We identified all patients (n = 35,289 admitted with a first AMI in the province of Quebec between January 1, 1996 and March 31, 1999 using population-based administrative databases. Medical resource utilization and non-fatal and fatal outcomes were compared among patients admitted to hospitals with and without on-site cardiac catheterization facilities. Results Cardiac catheterization and PCI were more frequently performed among patients admitted to hospitals with catheterization facilities. However, non-invasive procedures were not used more frequently at hospitals without catheterization facilities. To the contrary, echocardiography [odds ratio (OR, 2.04; 95% confidence interval (CI, 1.93–2.16] and multi-gated acquisition imaging (OR, 1.24; 95% CI, 1.17–1.32 were used more frequently at hospitals with catheterization, and exercise treadmill testing (OR, 1.02; 95% CI, 0.91–1.15 and Sestamibi/Thallium imaging (OR, 0.93; 95% CI, 0.88–0.98 were used similarly at hospitals with and without catheterization. Use of anti-ischemic medications and frequency of emergency room and physician visits, were similar at both types of institutions. Readmission rates for AMI-related cardiac complications and mortality were also similar [adjusted hazard ratio, recurrent AMI: 1.02, 95% CI, 0.89–1.16; congestive heart failure: 1.02; 95% CI, 0.90–1.15; unstable angina: 0.93; 95% CI, 0.85–1.02; mortality: 0.99; 95% CI, 0.93–1.05]. Conclusion Although on-site availability of cardiac catheterization facilities is associated with greater use of invasive cardiac procedures, non-availability of

    The effects of device and patient characteristics on health and economic outcomes in patients with cardiac implantable electronic devices (CIEDs) are unclear. Modeling can estimate costs and outcomes for patients with CIEDs under a variety of scenarios, varying battery longevity, comorbidities, and care settings. The objective of this analysis was to compare changes in patient outcomes and payer costs attributable to increases in battery life of implantable cardiac defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-D). We developed a Monte Carlo Markov model simulation to follow patients through primary implant, postoperative maintenance, generator replacement, and revision states. Patients were simulated in 3-month increments for 15 years or until death. Key variables included Charlson Comorbidity Index, CIED type, legacy versus extended battery longevity, mortality rates (procedure and all-cause), infection and non-infectious complication rates, and care settings. Costs included procedure-related (facility and professional), maintenance, and infections and non-infectious complications, all derived from Medicare data (2004-2014, 5% sample). Outcomes included counts of battery replacements, revisions, infections and non-infectious complications, and discounted (3%) costs and life years. An increase in battery longevity in ICDs yielded reductions in numbers of revisions (by 23%), battery changes (by 44%), infections (by 23%), non-infectious complications (by 10%), and total costs per patient (by 9%). Analogous reductions for CRT-Ds were 23% (revisions), 32% (battery changes), 22% (infections), 8% (complications), and 10% (costs). Based on modeling results, as battery longevity increases, patients experience fewer adverse outcomes and healthcare costs are reduced. Understanding the magnitude of the cost benefit of extended battery life can inform budgeting and planning decisions by healthcare providers and insurers.

    While guidelines mentioned supraglottic airway management in the case of out-of- hospital cardiac arrest, robust data of their impact on the patient outcome remain scare and results are inconclusive. To assess the impact of the airway strategy on the patient outcome we prospectively enrolled 2224 individuals suffering cardiac arrest who were treated by the Viennese municipal emergency medical service. To control for potential confounders, propensity score matching was performed. Patients were matched in four groups with a 1:1:1:1 ratio ( n=210/group) according to bag-mask-valve, laryngeal tube, endotracheal intubation and secondary endotracheal intubation after primary laryngeal tube ventilation. The laryngeal tube subgroup showed the lowest 30-day survival rate among all tested devices ( p<0.001). However, in the case of endotracheal intubation after primary laryngeal tube ventilation, survival rates were comparable to the primary endotracheal tube subgroup. The use of a laryngeal tube was independently and directly associated with mortality with an adjusted odds ratio of 1.97 (confidence interval: 1.14-3.39; p=0.015). Additionally, patients receiving laryngeal tube ventilation showed the lowest rate of good neurological performance (6.7%; p<0.001) among subgroups. However, if patients received endotracheal intubation after initial laryngeal tube ventilation, the outcome proved to be significantly better (9.5%; p<0.001). We found that the use of a laryngeal tube for airway management in cardiac arrest was significantly associated with poor 30-day survival rates and unfavourable neurological outcome. A primary endotracheal airway management needs to be considered at the scene, or an earliest possible secondary endotracheal intubation during both pre-hospital and in-hospital post-return of spontaneous circulation critical care seems crucial and most beneficial for the patient outcome.

    There are few data comparing outcome and the utility of severity of illness scoring systems following intensive care after out-of-hospital (OHCA), in-hospital (IHCA) and intensive care unit (ICUCA) cardiac arrest. We investigated survival, factors associated with survival and the correlation and accuracy of general and specific scoring systems, including the Apache III score and the OHCA score in OHCA, IHCA and ICUCA patients. Prospective analysis of data on all cardiac arrest patients treated in a tertiary hospital between August 1st 2008 and July 30th 2010. Collected data included resuscitation and post-resuscitation care data as defined by the Utstein Guidelines, Apache III on admission and the OHCA score on admission in OHCA and IHCA patients and after the arrest in ICUCA patients. Statistical methods were used to identify factors associated with outcome and the predictive ability and correlation of the aforementioned scores. Of a total of 3931 patients treated in the ICU, 51 were admitted following OHCA, 50 following IHCA and 22 suffered an ICUCA and had sustained return of spontaneous circulation (ROSC). Survival at 30 days was highest among ICUCAs (67%) followed by IHCAs (38%) and OHCAs (29%). Using multivariate analysis delay ROSC was the only independent predictor of survival. The OHCA score performed with moderate accuracy for predicting 30-day mortality (area under the curve 0.77 [0.69-0.86] and was slightly better than the Apache III score 0.71 (0.61-0.80). Using multiple logistic regression the Apache III and the OHCA score were both independent predictors of hospital survival and correlation between these two scores was weak (correlation coefficient of 0.244). Latency to ROSC seems to be the most important determinant of survival in patients following ICU care after a cardiac arrest in this single center trial. The OHCA score and the Apache III score offer moderate predictive accuracy in ICU cardiac arrest patients but correlated weakly with each

    Without heart transplantation, a large number of patients with failing hearts worldwide face poor outcomes. By means of cardiomyocyte regeneration, cardiac regeneration therapy is emerging with great promise as a means for restoring loss of cardiac function. However, the limited success of clinical trials using bone marrow-derived cells and myoblasts with heterogeneous constituents, transplanted at a wide range of cell doses, has led to disagreement on the efficacy of cell therapy. It is therefore essential to reevaluate the evidence for the efficacy of cell-based cardiac regeneration therapy, focusing on targets, materials, and methodologies. Meanwhile, the revolutionary innovation of cardiac regeneration therapy is sorely needed to help the millions of people who suffer heart failure from acquired loss of cardiomyocytes. Cardiac regeneration has been used only in limited species or as a developing process in the rodent heart; now, the possibility of cardiomyocyte turnover in the human heart is being revisited. In the pursuit of this concept, the use of cardiac stem/progenitor stem cells in the cardiac niche must be focused to usher in a second era of cardiac regeneration therapy for the severely injured heart. In addition, tissue engineering and cellular reprogramming will advance the next era of treatment that will enable current cell-based therapy to progress to "real" cardiac regeneration therapy. Although many barriers remain, the prevention of refractory heart failure through cardiac regeneration is now becoming a realistic possibility.

    Therapeutic hypothermia initiated with cardiopulmonary resuscitation improves neurologic outcomes and survival after prolonged cardiac arrest. However, the potential mechanism by which hypothermia improves neurologic outcomes remains unclear. In the current study, we investigated the effect of rapid head cooling on 96-hr neurologic outcomes and survival by heart rate variability analysis in a pig model of prolonged cardiac arrest. Prospective randomized controlled animal study. University-affiliated research laboratory. Yorkshire-X domestic pigs (Sus scrofa). A protocol of 10 mins of untreated ventricular fibrillation followed by 5 mins of cardiopulmonary resuscitation in a pig model of cardiac arrest was used in this study. Sixteen male domestic pigs weighing between 39 and 45 kg were randomized into two groups, hypothermia (n = 8) and control (n = 8). For the hypothermia group, intranasal-induced head cooling was initiated with cardiopulmonary resuscitation and persisted for 4 hrs after resuscitation. For the control group, cardiopulmonary resuscitation was started with normothermia. Time and frequency domain heart rate variability was calculated in 5-min sections of electrocardiographic recordings at baseline and 4 hrs after resuscitation. Neurologic outcomes were evaluated every 24 hrs during the 96-hr postresuscitation observation period. No differences in the baseline measurement and resuscitation outcome were observed between the groups. However, the 96-hr cerebral performance categories of the hypothermic group were significantly lower than control (1.0 ± 0.0 vs. 4.0 ± 1.9, p = .003). Four hrs after resuscitation, mean RR interval, heart rate variability triangular index, and normalized very-low-frequency power were restored to baseline in the hypothermia group. Square root of the mean squared differences of successive RR intervals and SD of instantaneous RR intervals were significantly improved in the cooled animals compared with controls. A significant

    Current guidelines for the management of out-of-hospital cardiac arrest (OHCA) recommend the use of prehospital epinephrine by initial responders. This recommendation was initially based on data from animal models of cardiac arrest and minimal human data, but since its inception, more human data regarding prehospital epinephrine in this setting are now available. Although out-of-hospital return of spontaneous circulation (ROSC) may be higher with the use of epinephrine, worse neurologic outcomes may be associated with its use. A systematic review of the literature was conducted by search of databases including PubMed, Embase, and OVID to identify studies comparing patients with OHCA who had received epinephrine before arrival to the hospital with those who had not. Studies were assessed for quality and bias, and data were abstracted from studies deemed appropriate for inclusion. A meta-analysis was conducted using a Mantel-Haenszel model for dichotomous outcomes. Outcomes studied were prehospital ROSC, survival at 1 month, survival to discharge, and positive neurologic outcome. A total of 14 studies with 655853 patients were included for the meta-analysis. The use of epinephrine for OHCA before arrival to the hospital was associated with a significant increase in ROSC (odds ratio, 2.86; P<.001) and a significant increase in the risk of poor neurologic outcome at the time of discharge (odds ratio 0.51, P=.008). There was no significant difference in survival at 1 month or survival to discharge. Use of epinephrine before arrival to the hospital for OHCA does not increase survival to discharge but does make it more likely for those who are discharged to have poor neurologic outcome. There is a need for additional randomized controlled trials. Copyright © 2015 Elsevier Inc. All rights reserved.

    Cardiac rehabilitation has a number of benefits for patients, yet participation in it is sub-optimal, especially in regional Australia. Innovative models of cardiac rehabilitation are needed to improve participation. Providing nurse mentors to support patients transitioning from hospital to home represents a new model of service delivery in Australia. To explore the impact of a home-based cardiac rehabilitation program in assisting patients to recover from Acute Coronary Syndrome and meeting the expectations of nurse mentors delivering the program. This case study was underpinned by the structure, process and outcomes model and occurred in three Australian hospitals 2008-2011. Thirteen patients recovering from acute coronary syndrome were interviewed by telephone and seven nurse mentors completed a survey after completing the program. Mentor perceptions concerning the structures of the home-based CR program included the timely recruitment of patients, mentor training to operationalise the program, commitment to development of the mentor role, and the acquisition of knowledge and skills about cognitive behavioural therapy and patient centred care. Processes included the therapeutic relationship between mentors and patients, suitability of the program and the promotion of healthier lifestyle behaviours. Outcomes identified that patients were satisfied with the program's audiovisual resources, and the level of support and guidance provided by their nurse mentors. Mentors believed that the program was easy to use in terms of its delivery. Patients believed the program assisted their recovery and were satisfied with the information, guidance and support received from mentors. There were positive signs that the program influenced patients' decisions to change unhealthy lifestyle behaviours. Outcomes highlighted both rewards and barriers associated with mentoring patients in their homes by telephone. Experience gained from developing a therapeutic relationship with

    Aim Previous studies have examined the association between quantitative computed tomography (CT) measures of cerebral edema and patient outcomes. It has been reported that a calculated gray matter to white matter attenuation ratio (GWR) of < 1.2 indicates a near 100% non-survivable injury post-cardiac arrest. The objective of the current study was to validate whether a GWR < 1.2 reliably indicates poor survival post-cardiac arrest. We also sought to determine the inter-rater variability among reviewers, and examine the utility of a novel GWR measurement to facilitate easier practical use. Methods We performed a retrospective analysis of post-cardiac arrest patients admitted to a single center from 2008 to 2012. Inclusion criteria were age ≥ 18 years, non-traumatic arrest, and available CT imaging within 24 hours after ROSC. Three independent physician reviewers from different specialties measured CT attenuation of pre-specified gray and white matter areas for GWR calculations. Results Out of 171 consecutive patients, 90 met the study inclusion criteria. Thirteen patients were excluded for technical reasons and/or significant additional pathology, leaving 77 head CT scans for evaluation. Median age was 66 years and 63% were male. In-hospital mortality was 65% and 70% of patients received therapeutic hypothermia. For the validation measurement, the intra-class correlation coefficient was 0.70. In our dataset, a GWR below 1.2 did not accurately predict mortality or poor neurological outcome (sensitivity 0.56–0.62 and specificity 0.63–0.81). A score below 1.1 predicted a near 100% mortality but was not a sensitive metric (sensitivity 0.14–0.20 and specificity 0.96–1.00). Similar results were found for the exploratory model. Conclusion A GWR < 1.2 on CT imaging within 24 hours after cardiac arrest was moderately specific for poor neurologic outcome and mortality. Based on our data, a threshold GWR < 1.1 may be a safer cut-off to identify patients with low

    Forty to sixty-six percent of patients resuscitated from cardiac arrest remain comatose, and historic outcome predictors are unreliable. Quantitative spectral analysis of continuous electroencephalography (cEEG) may differ between patients with good and poor outcomes. Consecutive patients with post-cardiac arrest hypoxic-ischemic coma undergoing cEEG were enrolled. Spectral analysis was conducted on artifact-free contiguous 5-min cEEG epochs from each hour. Whole band (1-30 Hz), delta (δ, 1-4 Hz), theta (θ, 4-8 Hz), alpha (α, 8-13 Hz), beta (β, 13-30 Hz), α/δ power ratio, percent suppression, and variability were calculated and correlated with outcome. Graphical patterns of quantitative EEG (qEEG) were described and categorized as correlating with outcome. Clinical outcome was dichotomized, with good neurologic outcome being consciousness recovery. Ten subjects with a mean age = 50 yrs (range = 18-65) were analyzed. There were significant differences in total power (3.50 [3.30-4.06] vs. 0.68 [0.52-1.02], p = 0.01), alpha power (1.39 [0.66-1.79] vs 0.27 [0.17-0.48], p < 0.05), delta power (2.78 [2.21-3.01] vs 0.55 [0.38-0.83], p = 0.01), percent suppression (0.66 [0.02-2.42] vs 73.4 [48.0-97.5], p = 0.01), and multiple measures of variability between good and poor outcome patients (all values median [IQR], good vs. poor). qEEG patterns with high or increasing power or large power variability were associated with good outcome (n = 6). Patterns with consistently low or decreasing power or minimal power variability were associated with poor outcome (n = 4). These preliminary results suggest qEEG metrics correlate with outcome. In some patients, qEEG patterns change over the first three days post-arrest.

    Myocardial recovery occurs in a small cohort of patients receiving left ventricular assist device (LVAD) support, but identification of candidates for device removal remains challenging. We hypothesized that hemodynamic evaluation using echocardiography and right heart catheter during temporary suspension of LVAD support (LVAD-off test) can assess cardiac recovery to predict successful device removal. To prove this hypothesis, we reviewed 44 patients who underwent LVAD-off test from January 2000 to March 2011 at Osaka University Hospital. Twenty-two of them underwent LVAD explant, 9 showed sustaining recovery (successful explant, SE-group); whereas 13 had a recurrent heart failure (failed explant, FE-group). The other 22 patients remained LVAD dependent (nonrecovery, NR-group). Echocardiography showed significant lower ejection fraction (LVEF) in NR-group than in SE- and FE-group after termination of LVAD support, but there was no difference between SE- and FE-group. On the other hand, elevation in pulmonary capillary wedge pressure (ΔPCWP) was significantly smaller in SE-group than in FE- and NR-groups. The degree of cardiac fibrosis significantly increased in FE- and NR-group during the LVAD support, while it did not increase in SE-group. The degree of cardiac fibrosis at the time of LVAD explantation correlated significantly with PCWP at LVAD halt and ΔPCWP, and it had significant impact on the outcome after LVAD weaning. In conclusion, the data obtained during LVAD-off test using echocardiography and right heart catheter significantly correlated with the degree of cardiac fibrosis at the time of LVAD explantation. LVAD-off test is a useful method to predict the successful LVAD explantation.

    Previous studies have shown that low blood pressure is associated with increased mortality and heart failure (HF) in patients with left ventricular dysfunction. Cardiac resynchronization therapy (CRT) was shown to increase systolic blood pressure (SBP). Therefore, we hypothesized that treatment with CRT would provide incremental benefit in patients with lower SBP values. The independent contribution of SBP to outcome was analyzed in 1267 patients with left bundle brunch block enrolled in Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy (MADIT-CRT). SBP was assessed as continuous measures and further categorized into approximate quintiles. The risk of long-term HF or death and CRT with defibrillator versus implantable cardioverter defibrillator benefit was assessed in multivariate Cox proportional hazards regression models. Multivariate analysis showed that in the implantable cardioverter defibrillator arm, each 10-mm Hg decrement of SBP was independently associated with a significant 21% (P2-fold risk-increase. CRT with defibrillator provided the greatest HF or mortality risk reduction in patients with SBPSBP≥136 mm Hg and hazard ratio of 0.94, P=0.808, with SBP>136 mm Hg (P for trend=0.001). In patients with mild HF, prolonged QRS, and left bundle brunch block, low SBP is related to higher risk of mortality or HF with implantable cardioverter defibrillator therapy alone. Treatment with CRT is associated with incremental clinical benefits in patients with lower baseline SBP values. URL: http://www.clinicaltrials.gov.

    Although cardiac myxomas remain an uncommon group of malignancies, they are the most common form of primary cardiac tumour. Clinical presentations can be varied with local cardiac haemodynamic consequences, valvular insufficiency or even embolic phenomena. We present a case of a 46-year-old man with chronic abdominal pain and discuss a number of diagnostic challenges that were confronted up until a definitive diagnosis of cardiac myxoma was made. The resultant outcome was excellent with the patient achieving complete recovery from long term disabling symptoms.

    Research on the correlation of serum bilirubin level with cardiac function as well as outcomes in heart failure patients with cardiac resynchronization therapy (CRT) has not yet been reported. The aim of this study was to analyze the relationship between change in serum bilirubin level and left ventricular reverse remodeling, and also to clarify the impact of bilirubin change on clinical outcomes in CRT patients. We evaluated 105 consecutive patients who underwent CRT. Patients who had no serum total-bilirubin data at both baseline and 3-9 months' follow-up or had died less than 3 months after CRT implantation were excluded. Accordingly, a total of 69 patients were included in the present analysis. The patients were divided into two groups: decreased bilirubin group (serum total-bilirubin level at follow-up≤that at baseline; n=48) and increased bilirubin group (serum total-bilirubin level at follow-up>that at baseline; n=21). Mean follow-up period was 39.3 months. In the decreased bilirubin group, mean left ventricular end-systolic diameter decreased from 54.5mm to 50.2mm (p=0.001) and mean left ventricular ejection fraction increased significantly from 29.8% to 37.0% (p=0.001). In the increased bilirubin group, there was no significant change in echocardiographic parameters from baseline to follow-up. In Kaplan-Meyer analysis, cardiac mortality combined with heart failure hospitalization in the increased bilirubin group was significantly higher than that in the decreased bilirubin group (log-rank p=0.018). Multivariate Cox regression analysis revealed that increased bilirubin was an independent predictor of cardiac mortality combined with heart failure hospitalization (OR=2.66, p=0.023). The change in serum bilirubin is useful for assessment of left ventricular reverse remodeling and prediction of outcomes in heart failure patients with CRT.

    Risum, Niels; Tayal, Bhupendar; Hansen, Thomas F

    2015-01-01

    BACKGROUND: Current guidelines suggest that patients with left bundle branch block (LBBB) be treated with cardiac resynchronization therapy (CRT); however, one-third do not have a significant activation delay, which can result in nonresponse. By identifying characteristic opposing wall contraction......, 2-dimensional strain echocardiography (2DSE) may detect true LBBB activation. OBJECTIVES: This study sought to investigate whether the absence of a typical LBBB mechanical activation pattern by 2DSE was associated with unfavorable long-term outcome and if this is additive to electrocardiographic...... whether typical LBBB contraction was present. The pre-defined outcome was freedom from death, left ventricular assist device, or heart transplantation over 4 years. RESULTS: Two-thirds of patients (63%) had a typical LBBB contraction pattern. During 4 years, 48 patients (23%) reached the primary endpoint...

    Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist (TOPCAT) patients with heart failure and preserved left ventricular ejection fraction assigned to spironolactone did not achieve a significant reduction in the primary composite outcome (time to cardiovascular death, aborted cardiac arrest, or hospitalization for management of heart failure) compared with patients receiving placebo. In a post hoc analysis, an ≈4-fold difference was identified in this composite event rate between the 1678 patients randomized from Russia and Georgia compared with the 1767 enrolled from the United States, Canada, Brazil, and Argentina (the Americas). To better understand this regional difference in clinical outcomes, demographic characteristics of these populations and their responses to spironolactone were explored. Patients from Russia/Georgia were younger, had less atrial fibrillation and diabetes mellitus, but were more likely to have had prior myocardial infarction or a hospitalization for heart failure. Russia/Georgia patients also had lower left ventricular ejection fraction and creatinine but higher diastolic blood pressure (all P<0.001). Hyperkalemia and doubling of creatinine were more likely and hypokalemia was less likely in patients receiving spironolactone in the Americas with no significant treatment effects in Russia/Georgia. All clinical event rates were markedly lower in Russia/Georgia, and there was no detectable impact of spironolactone on any outcomes. In contrast, in the Americas, the rates of the primary outcome, cardiovascular death, and hospitalization for heart failure were significantly reduced by spironolactone. This post hoc analysis demonstrated greater potassium and creatinine changes and possible clinical benefits with spironolactone in patients with heart failure and preserved ejection fraction from the Americas. http://www.clinicaltrials.gov.

    To investigate the influence of dosing frequency and dosage of adrenaline on outcomes of cardiopulmonary resuscitation (CPR). We conducted a retrospective observational study in a single medical centre and included adult patients who had suffered an in-hospital cardiac arrest between 2006 and 2012. We used multivariable logistic regression analysis to evaluate the associations between independent variables and outcomes. Adrenaline average dosing frequency was calculated as the total dosage of adrenaline administered during CPR divided by the duration of CPR. Body weight (BW) was analysed as an interaction term to investigate the effect of adrenaline dosage on outcomes. Favourable neurological outcome was defined as a score of 1 or 2 on the Cerebral Performance Category scale at hospital discharge. We included 896 patients in the analysis. After adjusting for multiple confounding factors, including CPR duration, the results indicated that higher adrenaline dosing frequency was associated with lower rates of survival (odds ratio (OR): 0.05, 95% confidence interval (CI): 0.01-0.23) and favourable neurological outcome at hospital discharge (OR: 0.02, 95% CI: 0.002-0.16). A significant interaction was noted between total adrenaline dosage and BW, which indicated that, with the same adrenaline dosage, the outcomes for patients with BW≥82.5kg would be worse than those for patients with lower BW. Higher adrenaline average dosing frequency may be associated with worse outcomes after CPR. Besides, according to current recommendations, patients with BW above 82.5kg may not receive adequate dose of adrenaline. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Bradycardia is a common finding in patients undergoing therapeutic hypothermia (TH) following out-of-hospital cardiac arrest (OHCA), presumably as a normal physiological response to low body temperature. We hypothesized that a normal physiological response with sinus bradycardia (SB) indicates less neurological damage and therefore would be associated with lower mortality. We studied 234 consecutive comatose survivors of OHCA with presumed cardiac etiology and shockable primary rhythm, who underwent a full 24-h TH-protocol (33°C) at a tertiary heart center (years: 2004-2010). Primary endpoint was 180-day mortality; secondary endpoint was favorable neurological outcome (180-day cerebral performance category: 1-2). SB, defined as sinus rhythm <50 beats per minute during TH, was present in 115 (49%) patients. Baseline characteristics including sex, witnessed arrest, bystander cardiopulmonary resuscitation and time to return of spontaneous circulation were not different between SB- and no-SB patients. However, SB-patients were younger, 57±14 vs. 63±14 years, p<0.001 and less frequently had known heart failure (7% vs. 20%, p<0.01). Patients experiencing SB during the hypothermia phase of TH had a 17% 180-day mortality rate compared to 38% in no-SB patients (p<0.001), corresponding to a 180-day hazard ratio (HRadjusted=0.45 (0.23-0.88, p=0.02)) in the multivariable analysis. Similarly, SB during hypothermia was directly associated with lower odds of unfavorable neurological outcome (ORunadjusted=0.42 (0.23-0.75, p<0.01). Sinus bradycardia during therapeutic hypothermia is independently associated with a lower 180-day mortality rate and may thus be a novel, early marker of favorable outcome in comatose survivors of OHCA.

    To investigate the impact of integrating a medical intensivist into a cardiac care unit (CCU) multidisciplinary team on the outcomes of CCU patients. We conducted a retrospective cohort study of 2239 CCU admissions between July 1, 2011, and July 1, 2013, which constituted patients admitted in the 12 months before and 12 months after the introduction of intensivists into the CCU multidisciplinary team. This team included a cardiologist, a medical intensivist, medical house staff, nurses, a pharmacist, a dietitian, and physical and respiratory therapists. The primary outcome was CCU mortality. Secondary outcomes included hospital mortality, CCU length of stay, hospital length of stay, and duration of mechanical ventilation. After the implementation of a multidisciplinary team approach, there was a significant decrease in both adjusted CCU mortality (3.5% vs 5.9%; P=.01) and hospital mortality (4.4% vs 11.1%; Pmultidisciplinary team approach in which an intensivist and a cardiologist comanage the critical care of CCU patients is feasible and may result in better patient outcomes.

    2008-10-01

    The association of conotruncal heart defects with 22q11.2 chromosomal microdeletions is well established. However, it is not clear whether particular types of conotruncal malformations or additional cardiovascular anomalies are associated with microdeletions. In addition, cardiac surgery outcome in children with conotruncal defects and del22q11.2 is not well described. We prospectively enrolled 214 children with conotruncal defects: 126 with tetralogy of Fallot (TOF), 18 with pulmonary atresia-ventricular septal defect (PA-VSD), 15 with truncus arteriosus communis (TAC) type I, one with interrupted aortic arch (IAA) type B, and 54 with the transposition of great arteries, who were consecutively hospitalized at the Pediatric Cardiology Department between 2003 and 2005. 22q11.2 microdeletion was identified by fluorescence in situ hybridization. The postoperative course following cardiac surgery was compared in patients with TOF and its more severe form, PA-VSD, with/without del22q11.2 (groups A and B) and TAC with/without del22q11.2 (groups C and D). In 15 of 214 patients, 22q11.2 microdeletion was diagnosed (in 11 with TOF/PA-VSD, in three with TAC, in one with IAA type B). In patients with TOF/PA-VSD and microdeletion anatomic features that were significantly associated with 22q11.2, deletion included right aortic arch (p = 0.018), aberrant right subclavian artery (p microdeletion. We conclude that additional cardiovascular anomalies are significantly more frequent in children with 22q11.2 microdeletion and TOF/PA-VSD. Children with conotruncal heart defects and 22q11.2 microdeletion more frequently experienced complicated postoperative course after cardiac surgery.

    To assess system-wide implementation of specific therapies focused on perfusion during cardiopulmonary resuscitation (CPR) and cerebral recovery after Return of Spontaneous Circulation (ROSC). Before and after retrospective analysis of an out-of-hospital cardiac arrest database. Implementation trial in the urban/suburban community of Alameda County, California, USA, population 1.6 million, from November 2009-December 2012. Adult patients with non-traumatic out-of-hospital cardiac arrest (OHCA) who received CPR and/or defibrillation. The impedance threshold device was used throughout this study and there was an increased use of mechanical CPR (mCPR) and in-hospital therapeutic hypothermia (HTH). Rates of ROSC, survival to hospital discharge and Cerebral Performance Category (CPC) scores were compared using univariate and multivariable analyses. A total of 2,926 adult non-traumatic patients with OHCA received CPR during the study period. From 2009-2011 to 2012, there was an increase in ROSC from 29.0% to 34.4% (p = 0.003) and a non-significant increase in hospital discharge from 10.2% to 12.0% (p = 0.16). There was a 76% relative increase in survival with favorable neurologic function between the two periods, as determined by CPC ≤ 2, from 4.5% to 7.9% (unadjusted OR = 1.80; CI = 1.31, 2.48; p improved survival by 74% with favorable neurologic function following OHCA.

    Early cardiopulmonary resuscitation together with early defibrillation is a key point in the chain of survival for cardiac arrest. Optimizing the timing of defibrillation by predicting the possibility of successful electric shock can guide treatments between defibrillation and cardiopulmonary resuscitation and improve the rate of restoration of spontaneous circulation. Numerous methods have been proposed for predicting defibrillation success based on quantification of the ventricular fibrillation waveform during past decades. To date, however, no analytical technique has been widely accepted for clinical application. In the present study, we investigate whether median stepping increment that is calculated from the Euclidean distance of consecutive points in Poincare plot could be used to predict the likelihood of successful defibrillation. Electrocardiographic recordings of out-of-hospital cardiac arrest patients were obtained from the external defibrillators. The performance of the proposed method was evaluated by receiver operating characteristic curve and compared with the results of other established features. The results indicated that median stepping increment has comparable performance to the established methods in predicting the likelihood of successful defibrillation.

    This study sought to evaluate the impact of sirolimus-eluting stent (SES) fractures on long-term clinical outcomes using multislice computed tomography (MSCT). In this study, 528 patients undergoing 6- to 18-month follow-up 64-slice MSCT after SES implantation without early clinical events were followed clinically (the median follow-up interval was 4.6 years). A CT-detected stent fracture was defined as a complete gap with Hounsfield units (HU) <300 at the site of separation. The major adverse cardiac events (MACEs), including cardiac death, stent thrombosis, and target lesion revascularisation, were compared according to the presence of stent fracture. Stent fractures were observed in 39 patients (7.4 %). MACEs were more common in patients with CT-detected stent fractures than in those without (46 % vs. 7 %, p < 0.01). Univariate Cox regression analysis indicated a significant relationship between MACE and stent fracture [hazard ratio (HR) 7.65; p < 0.01], age (HR 1.03; p = 0.04), stent length (HR 1.03; p < 0.01), diabetes mellitus (HR 1.77; p = 0.04), and chronic total occlusion (HR 2.54; p = 0.01). In the multivariate model, stent fracture (HR 5.36; p < 0.01) and age (HR 1.03; p = 0.04) remained significant predictors of MACE. An SES fracture detected by MSCT without early clinical events was associated with long-term clinical adverse events. (orig.)

    Dietary habits are widely reported to play a primary role in the occurrence of coronary artery disease (CAD). Cardiac rehabilitation is a multidisciplinary intervention that includes nutritional education. Proper nutrition plays an important role in cardiovascular health outcomes and in decreasing morbidity and mortality of cardiovascular diseases (CVD) as highlighted in the literature. The aim of this study was to assess the efficacy of an educational program to improve the diet of cardiac rehabilitation patients compared to usual treatment. 160 patients with CAD, (124 M, 36 F) were randomized into two groups. Data analysis was conducted on 133 patients (11 % dropped out). All enrolled patients attended two educational seminars about proper nutrition and cardiovascular prevention, and completed a questionnaire about dietary habits (before CAD). The Body Mass Index (BMI) was calculated, and basal glycaemia and plasma lipids were assessed at the beginning and at the end of the study (12 months after hospital discharge). The intervention group patients underwent a mid-term evaluation of nutrient intakes, BMI, and received a personalized educational reinforcement by a dietitian. At the end of the study, the intervention group was shown to have significantly reduced their daily caloric intake (reduction of total proteins, total fat, carbohydrate, alcohol), and showed a significant reduction of weight and BMI compared to the control group. Individual nutritional counseling session as a reinforcement of a standard educational program is effective in reducing caloric intake and BMI, which may reduce cardiovascular risk factors in cardiovascular patients.

    The role of emergency reperfusion therapy in patients with ST-elevation myocardial infarction (STEMI) resuscitated after an out-of-hospital cardiac arrest (OHCA) has not been clearly established yet. The aim of this study was to evaluate the in-hospital and postdischarge outcomes of STEMI patients surviving OHCA and undergoing emergency angioplasty (percutaneous coronary intervention [PCI]) within an established regional network. We prospectively collected data on 2,617 consecutive patients with STEMI treated with emergency PCI in 2005; in-hospital and 6-month outcomes of 99 patients who had experienced OHCA were compared with those of 2,518 patients without OHCA. The OHCA patients also underwent a cerebral performance evaluation after 12 months. OHCA patients were at higher clinical risk at presentation (cardiogenic shock 26% vs 5%, P < .0001). Percutaneous coronary intervention was successful in 80% of the OHCA and 89% of the non-OHCA patients (P = NS). In-hospital mortality rates were 22% and 3%, respectively (P < .0001). Independent predictors of in-hospital mortality among OHCA patients were longer delay between the call to the emergency medical system and the start of cardiopulmonary resuscitation (odds ratio [OR] 3.5, P = .03), nonshockable initial rhythms (OR 10.5, P = .002), cardiogenic shock (OR 3.05, P = .035), and a Glasgow Coma Scale score of 3 on admission (OR 2.9, P = .032). The 6-month composite rate of death, myocardial infarction, and revascularization among OHCA patients surviving the acute phase was comparable to that of non-OHCA patients (16% vs 13.9%, P = NS), and 87% of them showed a favorable neurologic recovery after 1 year. Resuscitated OHCA patients undergoing emergency PCI for STEMI have worse clinical presentation and higher in-hospital mortality compared to those without OHCA. However, subsequent cardiac events are similar, and neurologic recovery is more favorable than reported in most previous series.

    The prevalence of anaemia is increasing globally. It has a close association with perioperative blood transfusion which, in turn, results in an increased risk of postoperative complications. Undesirable effects are not only limited to short-term, but also have long-term implications. Despite this, many patients undergo cardiac surgery with undiagnosed and untreated anaemia. We designed a retrospective, observational study to estimate the prevalence of anaemia in patients having cardiac surgery in Auckland District Health Board, blood transfusion rates and associated clinical outcome. Two hundred of seven hundred and twelve (28.1%) patients were anaemic. Red blood cell (RBC) transfusion rates were significantly higher in the anaemic group compared to the non-anaemic group (160 (80%) vs. 192 (38%), p-value rates for fresh frozen plasma (FFP), cryoprecipitate and platelets were also higher in the anaemic group. Anaemia was significantly associated with the development of new infection (14 (7%) vs. 15 (2.9%), p-value 0.0193, RR (CI 95%) 2.389 (1.175-4.859)), prolonged ventilation time (47.01 hours vs. 23.59 hours, p-value 0.0076) and prolonged intensive care unit (ICU) stay (80.23 hours vs. 50.27, p-value 0.0011). Preoperative anaemia is highly prevalent and showed a clear link with significantly higher transfusion rates and postoperative morbidity. It is vital that a preoperative management plan for the correction of anaemia should be sought to improve patient safety and outcome. © The Author(s) 2014.

      Opium dependence is a recognized individual and public health threat, but little is known about its association with acute myocardial infarction (AMI) or sudden cardiac death (SCD). In a cross-sectional study followed by a one-year matched longitudinal cohort, all 569 men hospitalized with AMI in all Cardiac Care Units (CCU) of Isfahan, Iran, were recruited in a six-month period. In addition, 123 out-of-hospital deaths were included that were diagnosed as SCD at the same duration. Among those discharged alive, 126 opium dependents were matched with 126 nondependents (mostly nonusers) according to age and smoking status, and were followed for one year. Opium dependence was measured using the ICD10 criteria and Severity of Dependence Scale (SDS) questionnaire. The method was validated by morphine blood levels. Biochemical measurements, blood pressure, blood cell counts, anthropometrics, and ejection fraction were measured at baseline and repeated at the end of follow-up.  There were 118 (17.1%) patients with an average of 17.4 ± 10.4 years of abuse who met the criteria for opium dependency. Opium dependence decreased the age at event by 3.6 (95% CI: 1.2 - 6.0) years and was independent of smoking (P = 0.003). In terms of cardiovascular risk factors such as ejection fraction, in addition to post-AMI mortality and morbidity, no significant associations were noted at baseline or after one year of follow-up. The odds ratio of sustained smoking after AMI was 1.92 (95% CI: 1.04 - 3.52) in opium dependents (P = 0.033). Despite public opinion, opium did not improve cardiovascular risk factors, or post-AMI mortality and morbidity.

    Full Text Available Goal-directed therapy (GDT encompasses guidance of intravenous (IV fluid and vasopressor/inotropic therapy by cardiac output or similar parameters to help in early recognition and management of high-risk cardiac surgical patients. With the aim of establishing the utility of perioperative GDT using robust clinical and biochemical outcomes, we conducted the present study. This multicenter randomized controlled study included 130 patients of either sex, with European system for cardiac operative risk evaluation ≥3 undergoing coronary artery bypass grafting on cardiopulmonary bypass. The patients were randomly divided into the control and GDT group. All the participants received standardized care; arterial pressure monitored through radial artery, central venous pressure (CVP through a triple lumen in the right internal jugular vein, electrocardiogram, oxygen saturation, temperature, urine output per hour, and frequent arterial blood gas (ABG analysis. In addition, cardiac index (CI monitoring using FloTrac™ and continuous central venous oxygen saturation (ScVO2 using PreSep™ were used in patients in the GDT group. Our aim was to maintain the CI at 2.5–4.2 L/min/m2, stroke volume index 30–65 ml/beat/m2, systemic vascular resistance index 1500–2500 dynes/s/cm5/m2, oxygen delivery index 450–600 ml/min/m2, continuous ScVO2 >70%, and stroke volume variation 30%, and urine output >1 ml/kg/h. The aims were achieved by altering the administration of IV fluids and doses of inotropes or vasodilators. The data of sixty patients in each group were analyzed in view of ten exclusions. The average duration of ventilation (19.89 ± 3.96 vs. 18.05 ± 4.53 h, P = 0.025, hospital stay (7.94 ± 1.64 vs. 7.17 ± 1.93 days, P = 0.025, and Intensive Care Unit (ICU stay (3.74 ± 0.59 vs. 3.41 ± 0.75 days, P = 0.012 was significantly less in the GDT group, compared to the control group. The extra volume added and the number of inotropic dose adjustments were

    The effect of the number and level of on-scene emergency medical technicians (EMTs) on the outcomes of patients with out-of-hospital cardiac arrest (OHCA) remains unclear. We aimed to test the association between the number and level of EMTs and the outcomes of patients with OHCA. We analysed Utstein-based registry data on OHCA in Taipei from 2011 to 2015. The eligible patients were adults, aged ≥20 years, with non-traumatic OHCA who underwent resuscitation attempts. The exposures were the total number of EMTs or the EMT-Paramedic (EMT-P) ratio >50%. The outcome of interest was survival to discharge. During study period, total 8262 OHCA cases were included, of which 1085 (13.1%) were approached by crews with an EMT-P ratio >50%. While an increase in the number of EMTs on-scene was not associated with better chances of survival (adjusted odds ratio [aOR] 0.98, 95% confidence interval [CI] 0.89-1.08), an EMT-P ratio >50% was significantly associated with improved outcome (aOR 1.36, 95% CI 1.06-1.76). Subgroup analyses showed that EMT-P >50% significantly benefited survival in witnessed OHCA cases with non-shockable rhythm (aOR 1.69, 95% CI 1.01-2.58). Survival was the highest among cases seen by four EMTs with an EMT-P ratio >50% (aOR 2.54, 95% CI 1.43-4.50). An on-scene EMT-P ratio >50% was associated with improved survival to discharge of OHCA cases, especially in those with witnessed, non-shockable rhythm. The presence of four EMTs with an EMT-P ratio >50% at the scene of OHCA was associated with the best outcome. Copyright © 2017 Elsevier B.V. All rights reserved.

    . RESULTS: Of the 579 patients (265 men [80.3%]; mean [SD] age, 63 [12] years), 304 patients (52.5%) had a poor neurologic outcome at 6 months. In the discovery phase with short RNA sequencing in 50 patients, the brain-enriched miR-124-3p level was identified as a candidate prognostic variable...... for neurologic outcomes. In the validation cohort of 529 patients, mean (SD) levels of miR-124-3p were higher in patients with a poor outcome (8408 [12 465] copies/µL) compared with patients with a good outcome (1842 [3025] copies/μL; P p level was significantly associated with neurologic...... outcomes in the univariable analysis (odds ratio, 6.72; 95% CI, 4.53-9.97). In multivariable analyses using logistic regression, miR-124-3p levels were independently associated with neurologic outcomes (odds ratio, 1.62; 95% CI, 1.13-2.32). In Cox proportional hazards models, higher levels of miR-124-3p...

    Most thoracopagus twins present with cardiac fusion and associated congenital cardiac defects, and assessment of this anatomy is of critical importance in determining patient care and outcome. Cardiac CT with electrocardiographic triggering provides an accurate and quick morphological assessment of both intracardiac and extracardiac structures in newborns, making it the best imaging modality to assess thoracopagus twins during the neonatal period. In this case report, we highlight the diagnostic value of cardiac CT in thoracopagus twins with an interatrial channel and complex congenital cardiac defects. (orig.)

    Cardiac resynchronization therapy (CRT) is considered as a standard adjunct therapy in symptomatic patients with congestive heart failure (CHF) who have a prolonged QRS. There is an increasing number of patients who do not receive de novo CRT devices but are upgraded from right ventricular (RV) pacing to biventricular stimulation. We wanted to evaluate the benefit of CRT in patients with chronic RV pacing in comparison to previously non-paced heart failure patients. One hundred and sixty-five patients who had their device newly implanted (group I) and 116 who were upgraded from previously implanted RV pacing systems (group II) at Mayo Clinic Hospital were retrospectively analyzed. Clinical and echocardiographic response to CRT was evaluated. Mean follow-up time was 290±250days. Baseline characteristics did not differ between the two groups of patients. Clinical response rate was identical in Groups I and II (65 vs. 65%, respectively; P=0.98) and echocardiographic response rate was similar in both groups of patients (64 vs. 62%; P=0.80). Post-implant QRS increased in group I and was reduced in group II (5 (27.4) vs. -20.0 (33.9) ms; PChronically RV-paced patients who receive CRT have similar short-term benefits when compared with patients with new CRT implantations.

    To characterize neurodevelopmental outcomes after fetal aortic valvuloplasty for evolving hypoplastic left heart syndrome and determine the risk factors for adverse neurodevelopment. Questionnaires were mailed to families of children who underwent fetal aortic valvuloplasty from 2000 to 2012, and medical records were reviewed retrospectively. The primary outcome was the General Adaptive Composite score of the Adaptive Behavior Assessment System Questionnaire-Second Edition. Other questionnaires included the Behavior Assessment System for Children, Behavior Rating Inventory of Executive Function, Ages and Stages, and Pediatric Quality of Life Inventory. Among 69 eligible subjects, 52 (75%) completed questionnaires at median age of 5.5 (range 1.3-12) years; 30 (58%) had biventricular status circulation. The General Adaptive Composite mean score (92 ± 17) was lower than population norms (P Behavior Assessment System for Children, Behavior Rating Inventory of Executive Function, Ages and Stages, Pediatric Quality of Life Inventory), most subscale scores for patients with biventricular and single ventricular status were similar. Children who underwent fetal aortic valvuloplasty have neurodevelopmental delay, similar to patients with hypoplastic left heart syndrome without fetal intervention. Achievement of biventricular circulation was not associated with better outcomes. We infer that innate patient factors and morbidity during infancy have the greatest effect on neurodevelopmental outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

    To evaluate the utility of cardiovascular magnetic resonance (CMR)-derived myocardial strain measurement for the prediction of poor outcomes in patients with acute myocarditis We retrospectively analyzed data from 37 patients with acute myocarditis who underwent CMR. Left ventricular (LV) size, LV mass index, ejection fraction and presence of myocardial late gadolinium enhancement (LGE) were analyzed. LV circumferential strain (EccSAX), radial strain (ErrSAX) from mid-ventricular level short-axis cine views and LV longitudinal strain (EllLV), radial strain (ErrLax) measurements from 2-chamber long-axis views were obtained. In total, 31 of 37 patients (83.8%) underwent follow-up echocardiography. The primary outcome was major adverse cardiovascular event (MACE). Incomplete LV functional recovery was a secondary outcome. During an average follow-up of 41 months, 11 of 37 patients (29.7%) experienced MACE. Multivariable Cox proportional hazard regression analysis, which included LV mass index, LV ejection fraction, the presence of LGE, EccSAX, ErrSAX, EllLV, and ErrLax values, indicated that the presence of LGE (hazard ratio, 42.88; p = 0.014), together with ErrLax (hazard ratio, 0.77 per 1%, p = 0.004), was a significant predictor of MACE. Kaplan-Meier analysis demonstrated worse outcomes in patient with LGE and an ErrLax value ≤ 9.48%. Multivariable backward regression analysis revealed that ErrLax values were the only significant predictors of LV functional recovery (hazard ratio, 0.54 per 1%; p = 0.042). CMR-derived ErrLax values can predict poor outcomes, both MACE and incomplete LV functional recovery, in patients with acute myocarditis, while LGE is only a predictor of MACE.

    Heart failure (HF) is a major cause of morbidity and mortality, and ventricular dyssynchrony is an important contributor. The ReThinQ trial reported no improvement with cardiac resynchronization therapy (CRT) in HF patients with left ventricular ejection fraction (LVEF) PR interval. We retrospectivelyanalyzed the 87 patients from ReThinQ who were randomized to CRT. Patients were divided into two groups: baseline PR interval PR interval ≥180 ms. The primary outcome was change in VO2 max at 6 months; secondary outcomes were change in LVEF, 6-min walk distance, and change in NYHA class. Forty-six patients had PR PR ≥ 180 ms. The baseline characteristics were similar in the two groups. As compared to patients with a short PR interval, at 6 months, only patients with PR ≥ 180 ms showed a statistically significant increase in VO2 max from 12.2 to 13.6 mL/kg min (P = 0.045). Similarly, LVEF was significantly improved only in the long PR group (0.26 to 0.28, P = 0.038). A greater percentage of patients in the long PR group showed improvement by at least one NYHA class (59 vs. 35%, P = 0.033). A longer baseline PR interval may allow more efficacious delivery of CRT by allowing programming of physiologic AV delays. A short baseline PR interval may contribute to LV under-filling and CRT non-response.

    N-terminal pro-B-type natriuretic (NT-proBNP) is expressed in the heart and brain, and serum levels are elevated in acute heart and brain diseases. We aimed to assess the possible association between serum levels and neurological outcome and death in comatose patients resuscitated from out......-of-hospital cardiac arrest (OHCA). Of the 939 comatose OHCA patients enrolled and randomized in the Targeted Temperature Management (TTM) trial to TTM at 33°C or 36°C for 24 hours, 700 were included in the biomarker substudy. Of these, 647 (92%) had serum levels of NT-proBNP measured 24, 48, and 72 hours after return...... of spontaneous circulation (ROSC). Neurological outcome was evaluated by the Cerebral Performance Category (CPC) score and modified Rankin Scale (mRS) at 6 months. Six hundred thirty-eight patients (99%) had serum NT-proBNP levels ≥125 pg/ml. Patients with TTM at 33°C had significantly lower NT-proBNP serum...

    Chest pain is a common symptom for referring patients to emergency departments (ED). Among those referred, some are admitted to hospitals with a definite or tentative diagnosis of acute coronary syndrome and some are discharged with primary diagnosis of non-cardiac chest pain. This study aimed at investigating 30 days' adverse outcomes of patients discharged from ED of a major heart center in Iran. Out of 1638 chest pain admissions to the centre during 2010-2011, 962 patients (mean age= 50.9±15.9 years) who were admitted to Afshar Heart Center's ED with chest pain as their chief complaint, and discharged with primary diagnosis of non-cardiac chest pain, were followed for any adverse cardiac events 30 days post discharge. The adverse events were: unstable angina, non-ST-elevated myocardial infarction (NSTEMI), ST elevated myocardial infarction (STEMI), coronary revascularization (percutaneous angioplasty, coronary artery bypass grafting) and death. Adverse cardiac events, including acute coronary syndrome (ACS), revascularization and death were observed in 30 patients (3.1%) including: acute MI n=5 (0.5%, sudden cardiac death inn=1 (0.1%, coronary revascularization in n=8 (0.8%) and hospitalization due to unstable angina/NSTEMI in n=16 (1-7%). Adverse events were seen more frequently in patients with history of hypertension, dyslipidemia and previous coronary artery disease. In univariate analysis, the chance of postdischarge adverse cardiac events was higher in patients with hypertension (OR=9.36, CI=3.24-27.03), previous coronary artery disease (OR= 3.8, CI=1.78-8.0), dyslipidemia (OR=3.5, CI=1.7-7.38) and discharge against medical advice (OR=2.85, CI= 1.37-5.91). The extent of adverse cardiac events in patients with a primary diagnosis of non-cardiac chest pain within 30 days of discharge was significant, mandating nation-wide registries to provide better care for these patients.

    This study sought to determine the effects of abnormal left ventricular (LV) architecture on cardiac remodeling and clinical outcomes in mild heart failure (HF). Cardiac resynchronization therapy (CRT) is an established treatment for HF that improves survival in part by favorably remodeling LV architecture. LV shape is a dynamic component of LV architecture on which contractile function depends. Transthoracic 2-dimensional echocardiography was used to quantify changes in LV architecture over 5 years of follow-up of patients with mild HF from the REVERSE study. REVERSE was a prospective study of patients with large hearts (LV end-diastolic dimension ≥55 mm), LV ejection fraction 120 ms randomly assigned to CRT-ON (n = 419) and CRT-OFF (n = 191). CRT-OFF patients were excluded from this analysis. LV dimensions, volumes, mass index, and LV ejection fraction were calculated. LV architecture was assessed using the sphericity index, as follows: (LV end-diastolic volume)/(4/3 × π × r 3 ) × 100%. LV architecture improved over time and demonstrated significant associations between LV shape, age, sex, and echocardiography metrics. Changes in LV architecture were strongly correlated with changes in LV end-systolic volume index and LV end-diastolic volume index (both p 15% occurred in more than two-thirds of patients, which indicates considerable reverse remodeling. We demonstrated that change in LV architecture in patients with mild HF with CRT is associated with structural and functional remodeling. Mean LV filling pressure was elevated, and the inability to lower it was an additional predictor of HF hospitalization or death.

    Chest compression quality is a determinant of survival from out-of-hospital cardiac arrest (OHCA). ERC 2005 guidelines recommend the use of technical devices to support rescuers giving compressions. This prospective randomized study reviewed influence of different feedback configurations on survival and compression quality. 312 patients suffering an OHCA were randomly allocated to two different feedback configurations. In the limited feedback group a metronome and visual feedback was used. In the extended feedback group voice prompts were added. A training program was completed prior to implementation, performance debriefing was conducted throughout the study. Survival did not differ between the extended and limited feedback groups (47.8% vs 43.9%, p = 0.49). Average compression depth (mean ± SD: 4.74 ± 0.86 cm vs 4.84 ± 0.93 cm, p = 0.31) was similar in both groups. There were no differences in compression rate (103 ± 7 vs 102 ± 5 min(-1), p=0.74) or hands-off fraction (16.16% ± 0.07 to 17.04% ± 0.07, p = 0.38). Bystander CPR, public arrest location, presenting rhythm and chest compression depth were predictors of short term survival (ROSC to ED). Even limited CPR-feedback combined with training and ongoing debriefing leads to high chest compression quality. Bystander CPR, location, rhythm and chest compression depth are determinants of survival from out of hospital cardiac arrest. Addition of voice prompts does neither modify CPR quality nor outcome in OHCA. CC depth significantly influences survival and therefore more focus should be put on correct delivery. Further studies are needed to examine the best configuration of feedback to improve CPR quality and survival. ClinicalTrials.gov (NCT00449969), http://www.clinicalTrials.gov.

    Aims We investigated the prevalence of prior myocardial infarction (MI) and incidence of ischaemic cardiovascular (CV) events among atrial fibrillation (AF) patients. Methods and results In ROCKET AF, 14 264 patients with nonvalvular AF were randomized to rivaroxaban or warfarin. The key efficacy outcome for these analyses was CV death, MI, and unstable angina (UA). This pre-specified analysis was performed on patients while on treatment. Rates are per 100 patient-years. Overall, 2468 (17%) patients had prior MI at enrollment. Compared with patients without prior MI, these patients were more likely to be male (75 vs. 57%), on aspirin at baseline (47 vs. 34%), have prior congestive heart failure (78 vs. 59%), diabetes (47 vs. 39%), hypertension (94 vs. 90%), higher mean CHADS2 score (3.64 vs. 3.43), and fewer prior strokes or transient ischaemic attacks (46 vs. 54%). CV death, MI, or UA rates tended to be lower in patients assigned rivaroxaban compared with warfarin [2.70 vs. 3.15; hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.73–1.00; P = 0.0509]. CV death, MI, or UA rates were higher in those with prior MI compared with no prior MI (6.68 vs. 2.19; HR 3.04, 95% CI 2.59–3.56) with consistent results for CV death, MI, or UA for rivaroxaban compared with warfarin in prior MI compared with no prior MI (P interaction = 0.10). Conclusion Prior MI was common and associated with substantial risk for subsequent cardiac events. Patients with prior MI assigned rivaroxaban compared with warfarin had a non-significant 14% reduction of ischaemic cardiac events. PMID:24132190

    Cardiac allograft vasculopathy is an important cause of long-term graft loss. In adults, percutaneous revascularization procedures (PRPs) have variable success with high restenosis rates and little impact on graft survival. Limited data exist in pediatric recipients of transplants. Data from the Pediatric Heart Transplant Study (PHTS) were used to explore associations between PRPs and outcomes after heart transplant in patients listed ≤18 years old who received a first heart transplant between 1993 and 2009. Revascularization procedures were done in 28 of 3,156 (0.9%) patients; 13 patients had multiple PRPs giving a total of 51 PRPs performed across 15 centers. Mean recipient age at time of transplant was 7.7 ± 6.7 years; mean donor age was 15.9 ± 15.4 years. The mean time to first PRP was 5.7 ± 3.2 years. Vessels involved were left anterior descending artery (41%), right coronary artery (25%), circumflex artery (18%), other coronary branches/unknown (16%). PRPs consisted of 38 (75%) stent implantations and 13 (25%) balloon angioplasties with an overall procedural success rate of 73%. Freedom from graft loss after PRPs was 89%, 75%, and 61% at 1, 3, and 12 months. In addition, patients with transplants from donors >30 years old were found to have less freedom from the need for a revascularization procedure than patients with transplants from younger donors (p heart transplant cohort, use of PRPs for cardiac allograft vasculopathy was rare, likely related to procedural feasibility of the interventions. Despite technically successful interventions, graft loss occurred in 39% within 1 year post-procedure; relisting for heart transplant should be considered.

    Cardiac resynchronization therapy (CRT) is associated with improved morbidity and mortality in patients with chronic heart failure (CHF) on optimal medical therapy. The impact of CHF medication optimization following CRT, however, has never been comprehensively evaluated. In the current study, we therefore investigated the effect of CHF medication dosage on morbidity and mortality in CHF patients after CRT implantation. Chronic heart failure medication was assessed in 185 patients after CRT implantation. During an overall mean follow-up of 44.6 months, 83 patients experienced a primary endpoint (death, heart transplantation, assist device implantation, or hospitalization for CHF). Treatment with higher dosages of angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin receptor blockers (ARBs) (P = 0.001) and beta-blockers (P < 0.001) as well as with lower dosages of loop diuretics (P < 0.001) was associated with a reduced risk for the primary combined endpoint as well as for all-cause mortality. Echocardiographic super-responders to CRT were treated with higher average dosages of ACE-I/ARBs (68.1 vs. 52.4%, P < 0.01) and beta-blockers (59 vs. 42.2%, P < 0.01). During follow-up, the average dosage of loop diuretics was decreased by 20% in super-responders, but increased by 30% in non-super-responders (P < 0.03). The use of higher dosages of neurohormonal blockers and lower dosages of diuretics is associated with reduced morbidity and mortality following CRT implantation. Our data imply a beneficial effect of increasing neurohormonal blockade whenever possible following CRT implantation.

    Insulin resistance is highly prevalent among patients with atherosclerosis and is associated with an increased risk for myocardial infarction (MI) and stroke. The IRIS trial (Insulin Resistance Intervention after Stroke) demonstrated that pioglitazone decreased the composite risk for fatal or nonfatal stroke and MI in patients with insulin resistance without diabetes mellitus, after a recent ischemic stroke or transient ischemic attack. The type and severity of cardiac events in this population and the impact of pioglitazone on these events have not been described. We performed a secondary analysis of the effects of pioglitazone, in comparison with placebo, on acute coronary syndromes (MI and unstable angina) among IRIS participants. All potential acute coronary syndrome episodes were adjudicated in a blinded fashion by an independent clinical events committee. The study cohort was composed of 3876 IRIS participants, mean age 63 years, 65% male, 89% white race, and 12% with a history of coronary artery disease. Over a median follow-up of 4.8 years, there were 225 acute coronary syndrome events, including 141 MIs and 84 episodes of unstable angina. The MIs included 28 (19%) with ST-segment elevation. The majority of MIs were type 1 (94, 65%), followed by type 2 (45, 32%). Serum troponin was 10× to 100× upper limit of normal in 49 (35%) and >100× upper limit of normal in 39 (28%). Pioglitazone reduced the risk of acute coronary syndrome (hazard ratio, 0.71; 95% confidence interval, 0.54-0.94; P =0.02). Pioglitazone also reduced the risk of type 1 MI (hazard ratio, 0.62; 95% confidence interval, 0.40-0.96; log-rank P =0.03), but not type 2 MI (hazard ratio, 1.05; 95% confidence interval, 0.58-1.91; P =0.87). Similarly, pioglitazone reduced the risk of large MIs with serum troponin >100× upper limit of normal (hazard ratio, 0.44; 95% confidence interval, 0.22-0.87; P =0.02), but not smaller MIs.

    Background Utilization of cardiac rehabilitation is suboptimal. The aim of the study was to assess referral trends over the past decade, to identify predictors for referral to a cardiac rehabilitation program, and to evaluate the association with one-year mortality in a large national registry of acute coronary syndrome patients. Design and methods Data were extracted from the Acute Coronary Syndrome Israeli Survey national surveys between 2006-2013. A total of 6551 patients discharged with a diagnosis of acute coronary syndrome were included. Results Referral to cardiac rehabilitation following an acute coronary syndrome increased from 38% in 2006 to 57% in 2013 ( p for trend following independent predictors for non-referral: 2006 survey, older age, female sex, past stroke, heart or renal failure, prior myocardial infarction, minority group, and lack of in-hospital cardiac rehabilitation center (all p follow-up ( p = 0.03). Consistently, a 32% lower one-year mortality risk was evident in a propensity score matched group of 3340 patients (95% confidence interval 0.48-0.95, p = 0.02). Conclusions Over the past decade there was a significant increase in cardiac rehabilitation referral following an acute coronary syndrome. However, cardiac rehabilitation is still under-utilized in important high-risk subsets of this population. Patients referred to cardiac rehabilitation have a lower adjusted mortality risk.

The global shortage of deceased organ donors caused increasing interest to the transplant program based on the use of organs from the donors with sudden irreversible cardiac arrest, or asystolic donors (DCD. Ischemia-reperfusion injury as a result of cardiac arrest remains a key problem that limits the use of organs from DCD. Our clinical study was intended to determine the acceptability of renal transplants derived from the DCD using extracorporeal perfusion in situ after 60 minutes of asystole. Materials and methods. In 2009–2014, St. Petersburg Organ Procurement Organization (OPO obtained kidneys from 29 DCD with critically expanded warm ischemic time (WIT.

    Observational studies have documented an off-pump over on-pump advantage for high-risk patients, including diabetic patients. Randomized trials have not confirmed this advantage. The VA Randomization On Versus Off Bypass (ROOBY) trial randomly assigned 2,203 coronary artery bypass graft surgery (CABG) patients at 18 sites to either on-pump (n=1,099) or off-pump (n=1,104) procedures. An a priori ROOBY aim was to evaluate treatment impact on diabetic patients. Actively treated diabetic patients (n=835, receiving oral hypoglycemic or insulin medications) received off-pump CABG (n=402) or on-pump CABG (n=433). The primary ROOBY trial endpoints were a short-term composite (30-day operative death or major complications) and a 1-year composite (death, nonfatal acute myocardial infarction, or repeat revascularization). Secondary ROOBY endpoints included 1-year all-cause death, 1-year graft patency, 1-year changes from baseline in neurocognitive status and health-related quality of life, and costs. Diabetic patients' risk factors at baseline were balanced across treatments. For diabetic patients, the primary short-term composite outcome rate showed a worse trend for off-pump (8.0%) than on-pump (3.9%, p=0.013), with no difference in the 1-year primary composite outcome or 1-year death rate. One-year patency was 83.1% off-pump versus 88.4% on-pump (p=0.004). No differences were found in neurocognitive, health-related quality of life, discharge cost, and 1-year cumulative cost. Concordant with the ROOBY trial's overall findings, off-pump CABG yielded no advantage over on-pump CABG for actively treated diabetic patients. The 1-year graft patency was lower and the short-term composite trended higher for off-pump CABG, with no other significant outcome or cost differences.

    Full Text Available OBJECTIVE: Left ventricular (LV remodeling following myocardial infarction (MI is characterized by progressive alterations of structure and function, named LV remodeling. Although several risk factors such as infarct size have been identified, LV remodeling remains difficult to predict in clinical practice. Changes within the extracellular matrix, involving matrix metalloproteinases (MMPs and tissue inhibitors of metalloproteinases (TIMPs, are an integral part of left ventricular (LV remodeling after myocardial infarction (MI. We investigated the temporal profile of circulating MMPs and TIMPs and their relations with LV remodeling at 1 year and clinical outcome at 3 years in post-MI patients. METHODS: This prospective multicentre study included 246 patients with a first anterior MI. Serial echocardiographic studies were performed at hospital discharge, 3 months, and 1 year after MI, and analysed at a core laboratory. LV remodeling was defined as the percent change in LV end-diastolic volume (EDV from baseline to 1 year. Serum samples were obtained at hospital discharge, 1, 3, and 12 months. Multiplex technology was used for analysis of MMP-1, -2, -3, -8, -9, -13, and TIMP-1, -2, -3, -4 serum levels. RESULTS: Baseline levels of MMP-8 and MMP-9 were positively associated with changes in LVEDV (P = 0.01 and 0.02, respectively. When adjusted for major baseline characteristics, MMP-8 levels remained an independent predictor LV remodeling (P = 0.025. By univariate analysis, there were positive relations between cardiovascular death or hospitalization for heart failure during the 3-year follow-up and the baseline levels of MMP-2 (P = 0.03, MMP-8 (P = 0.002, and MMP-9 (P = 0.03. By multivariate analysis, MMP-8 was the only MMP remaining significantly associated with clinical outcome (P = 0.02. CONCLUSION: Baseline serum MMP-8 is a significant predictor of LV remodeling and cardiovascular outcome after MI and may help to improve

    Quantitative ventricular fibrillation (VF) waveform analysis is a potentially powerful tool to optimize defibrillation. However, whether combining VF features with additional attributes that related to the previous shock could enhance the prediction performance for subsequent shocks is still uncertain. A total of 528 defibrillation shocks from 199 patients experienced out-of-hospital cardiac arrest were analyzed in this study. VF waveform was quantified using amplitude spectrum area (AMSA) from defibrillator's ECG recordings prior to each shock. Combinations of AMSA with previous shock index (PSI) or/and change of AMSA (ΔAMSA) between successive shocks were exercised through a training dataset including 255shocks from 99patientswith neural networks. Performance of the combination methods were compared with AMSA based single feature prediction by area under receiver operating characteristic curve(AUC), sensitivity, positive predictive value (PPV), negative predictive value (NPV) and prediction accuracy (PA) through a validation dataset that was consisted of 273 shocks from 100patients. A total of61 (61.0%) patients required subsequent shocks (N = 173) in the validation dataset. Combining AMSA with PSI and ΔAMSA obtained highest AUC (0.904 vs. 0.819, pdefibrillation outcome for subsequent shocks.

    Liver transplantation (LT) using organs donated after cardiac death (DCD) is increasing due, in large part, to a shortage of organs. The outcome of using DCD organs in recipients with hepatits C virus (HCV) infection remains unclear due to the limited experience and number of publications addressing this issue. To evaluate the clinical outcomes of DCD versus donation after brain death (DBD) in HCV-positive patients undergoing LT. Studies comparing DCD versus DBD LT in HCV-positive patients were identified based on systematic searches of seven electronic databases and multiple sources of gray literature. The search identified 58 citations, including three studies, with 324 patients meeting eligibility criteria. The use of DCD livers was associated with a significantly higher risk of primary nonfunction (RR 5.49 [95% CI 1.53 to 19.64]; P=0.009; I2=0%), while not associated with a significantly different patient survival (RR 0.89 [95% CI 0.37 to 2.11]; P=0.79; I2=51%), graft survival (RR 0.40 [95% CI 0.14 to 1.11]; P=0.08; I2=34%), rate of recurrence of severe HCV infection (RR 2.74 [95% CI 0.36 to 20.92]; P=0.33; I2=84%), retransplantation or liver disease-related death (RR 1.79 [95% CI 0.66 to 4.84]; P=0.25; I2=44%), and biliary complications. While the literature and quality of studies assessing DCD versus DBD grafts are limited, there was significantly more primary nonfunction and a trend toward decreased graft survival, but no significant difference in biliary complications or recipient mortality rates between DCD and DBD LT in patients with HCV infection. There is insufficient literature on the topic to draw any definitive conclusions.

    Controlled donation after cardiac death (CDCD) is increasingly common for liver transplantation due to donor shortage. However, the outcomes, in terms of grafts and recipients, remain unclear. The current study is a systematic review and meta-analysis that compared CDCD with donation after brain death (DBD). We conducted an electronic search of MEDLINE, EMBASE, and the Cochrane Database (from January 2007 to May 2017). Studies reporting Maastricht category III or IV CDCD liver transplantation were screened for inclusion. We appraised studies using the Newcastle-Ottawa scale and meta-analyzed using a fixed or random effects model. A total of 21 studies, with 12,035 patients, were included in data analysis. CDCD did not differ from DBD in patient survival (hazard ration: 1.20; 95% confidence interval [CI]: 0.98 to 1.47; P = .07), graft survival (hazard ratio: 1.24; 95% CI: 0.99 to 1.56; P = .06), primary nonfunction (odds ratio [OR]: 1.74; 95% CI: 1.00 to 3.03; P = .05), hepatic artery thrombosis (OR: 1.17; 95% CI: 0.78 to 1.74; P = .45). However, CDCD was associated with biliary complications (OR: 2.48; 95% CI: 2.05 to 3.00), retransplantation (OR: 2.54; 95% CI: 1.99 to 3.26), and peak alanine aminotransferase (weighted mean difference: 330.88; 95% CI: 259.88 to 401.87). A subgroup analysis that included only hepatitis C virus (HCV)-positive recipients showed no significant difference between CDCD and DBD in biliary complications (P = .16), retransplantion (P = .15), HCV recurrence (P = .20), and peak alanine aminotransferase (P = .06). CDCD transplantation is the most viable alternative to DBD transplantation in the current critical shortage of liver organs. HCV infection may not be the inferior factor of postoperative outcomes and survival. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available We retrospectively evaluated correlations between cardiac manifestations and globotriaosylceramide (Gb3 accumulation in cardiomyocytes from Taiwanese patients with Fabry disease and the IVS4+919G>A (IVS4 mutation who underwent endomyocardial biopsy (Shire; Fabry Outcome Survey data; extracted January 2015. Of 24 males and six females (median age [Q1; Q3] at biopsy 60.4 [57.4; 64.1] and 61.3 [60.4; 65.1] years, respectively, 13 males (54.2% and five females (83.3% received agalsidase alfa enzyme replacement therapy (ERT before biopsy. Median left ventricular mass indexed to height (LVMI within ±6 months of biopsy was 65.3 (52.7; 93.1 in males and 53.2 (42.0; 55.0 g/m2.7 in females. A moderate, positive, statistically significant correlation was found between the percentage area Gb3 accumulation in cardiomyocytes and LVMI (Spearman’s ρ, 0.45; p = 0.014; a smaller, positive, non-statistically significant correlation was observed between cardiomyocyte diameter and LVMI (Spearman’s ρ 0.16, p = 0.394. Moderate, statistically significant, negative correlations were found between Gb3 accumulation and ERT duration (Spearman’s ρ, −0.49, p = 0.007 and between cardiomyocyte size and ERT duration (Spearman’s ρ, −0.37, p = 0.048. Longer ERT duration was associated with smaller amounts of Gb3 accumulation and smaller cardiomyocyte size. Further follow-up is recommended to confirm these trends in a larger sample size.

    This study aimed to evaluate if the microcirculation is impaired during and after therapeutic hypothermia (TH) in children with return of spontaneous circulation after cardiac arrest (CA) and to assess if microcirculatory impairment predicts mortality. This has been reported for post-CA adults, but results might be different for children because etiology, pathophysiology, and mortality rate differ. This prospective observational cohort study included consecutive, non-neonatal post-CA children receiving TH upon intensive care admission between June 2008 and June 2012. Also included were gender-matched and age-matched normothermic, control children without cardiorespiratory disease. The buccal microcirculation was non-invasively assessed with Sidestream Dark Field Imaging at the start of TH, halfway during TH, at the start of re-warming, and at normothermia. Macrocirculatory, respiratory, and biochemical parameters were also collected. Twenty post-CA children were included of whom 9 died. During hypothermia, the microcirculation was impaired in the post-CA patients and did not change over time. At normothermia, the core body temperature and the microcirculation had increased and no longer differed from the controls. Microcirculatory deterioration was associated with mortality in the post-CA patients. In particular, the microcirculation was more severely impaired at TH start in the non-survivors than in the survivors - positive predictive value: 73-83, negative predictive value: 75-100, sensitivity: 63-100%, and specificity: 70-90%. The microcirculation is impaired in post-CA children during TH and more severe impairment at TH start was associated with mortality. After the stop of TH, the microcirculation improves rapidly irrespective of outcome. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The long-term impact of cardiac resynchronization therapy (CRT)-induced acute improvement in left ventricular (LV) function is largely unknown. The goal of this study was to evaluate the significance of acute improvement in LV function resulting from CRT in patients with chronic heart failure (HF). The authors compared 6-month clinical composite score (CCS) and LV end-systolic (ESV) reduction (≥15% from baseline) response rates of CRT-treated patients enrolled in the Predictors of Response to CRT (PROSPECT) trial who showed an acute increase (≥15% from baseline) in LV ejection fraction (EF) vs those who did not show a similar change in EF. Of the 396 patients who had pre-implant and post-implant EF measurements, 78 (19.7%) had an increase in EF and 318 (80.3%) did not. Acute reduction of mitral regurgitation by at least one grade occurred in 26% and 23% of patients with and without an acute increase in EF, respectively. Patients with an acute increase in EF had significantly lower baseline EF and smaller LV volumes but otherwise similar characteristics. At 6 months, LVEF and LV volumes were significantly higher and lower in the increased EF group, respectively; however, CCS improvement (70.5% vs 69.5%) and LVESV reduction (57.1% vs 54.9%) response rates were comparable in the two groups. An acute ≥15% increase in LVEF with CRT does not predict 6-month effects of CRT on patient outcomes or LV reverse remodeling. That such findings occur in patients with smaller LV volumes, however, may provide additional insight into the mechanisms responsible for CRT-induced long-term improvement in LV function and clinical benefit. © 2011 Wiley Periodicals, Inc.

    Sudden cardiac arrest (SCA) is the leading cause of death in athletes during exercise. The effectiveness of school-based automated external defibrillator (AED) programmes has not been established through a prospective study. A total of 2149 high schools participated in a prospective observational study beginning 1 August 2009, through 31 July 2011. Schools were contacted quarterly and reported all cases of SCA. Of these 95% of schools confirmed their participation for the entire 2-year study period. Cases of SCA were reviewed to confirm the details of the resuscitation. The primary outcome was survival to hospital discharge. School-based AED programmes were present in 87% of participating schools and in all but one of the schools reporting a case of SCA. Fifty nine cases of SCA were confirmed during the study period including 26 (44%) cases in students and 33 (56%) in adults; 39 (66%) cases occurred at an athletic facility during training or competition; 55 (93%) cases were witnessed and 54 (92%) received prompt cardiopulmonary resuscitation. A defibrillator was applied in 50 (85%) cases and a shock delivered onsite in 39 (66%). Overall, 42 of 59 (71%) SCA victims survived to hospital discharge, including 22 of 26 (85%) students and 20 of 33 (61%) adults. Of 18 student-athletes 16 (89%) and 8 of 9 (89%) adults who arrested during physical activity survived to hospital discharge. High school AED programmes demonstrate a high survival rate for students and adults who suffer SCA on school campus. School-based AED programmes are strongly encouraged.

  5. Combining Amplitude Spectrum Area with Previous Shock Information Using Neural Networks Improves Prediction Performance of Defibrillation Outcome for Subsequent Shocks in Out-Of-Hospital Cardiac Arrest Patients.

    Full Text Available Quantitative ventricular fibrillation (VF waveform analysis is a potentially powerful tool to optimize defibrillation. However, whether combining VF features with additional attributes that related to the previous shock could enhance the prediction performance for subsequent shocks is still uncertain.A total of 528 defibrillation shocks from 199 patients experienced out-of-hospital cardiac arrest were analyzed in this study. VF waveform was quantified using amplitude spectrum area (AMSA from defibrillator's ECG recordings prior to each shock. Combinations of AMSA with previous shock index (PSI or/and change of AMSA (ΔAMSA between successive shocks were exercised through a training dataset including 255shocks from 99patientswith neural networks. Performance of the combination methods were compared with AMSA based single feature prediction by area under receiver operating characteristic curve(AUC, sensitivity, positive predictive value (PPV, negative predictive value (NPV and prediction accuracy (PA through a validation dataset that was consisted of 273 shocks from 100patients.A total of61 (61.0% patients required subsequent shocks (N = 173 in the validation dataset. Combining AMSA with PSI and ΔAMSA obtained highest AUC (0.904 vs. 0.819, p<0.001 among different combination approaches for subsequent shocks. Sensitivity (76.5% vs. 35.3%, p<0.001, NPV (90.2% vs. 76.9%, p = 0.007 and PA (86.1% vs. 74.0%, p = 0.005were greatly improved compared with AMSA based single feature prediction with a threshold of 90% specificity.In this retrospective study, combining AMSA with previous shock information using neural networks greatly improves prediction performance of defibrillation outcome for subsequent shocks.

    Defibrillation by bystanders and first responders has been associated with increased survival, but limited data are available from non-metropolitan areas. We examined time from 911-call to defibrillation (according to who defibrillated patients) and survival in North Carolina. Through the Cardiac Arrest Registry to Enhance Survival, we identified 1732 defibrillated out-of-hospital cardiac arrests from counties with complete case capture (population 2.7 million) from 2010 to 2013. Most patients (60.9%) were defibrillated in > 10 min. A minority (8.0%) was defibrillated defibrillated by first responders (51.8%) and bystanders (33.1%), independent of location of arrest (residential or public). Bystanders initiated cardiopulmonary resuscitation (CPR) in 49.0% of cases and defibrillated 13.4% of those. Survival decreased with increasing time to defibrillation ( 10 min: 13.2%). Odds of survival with favorable neurologic outcome adjusted for age, sex, and bystander CPR improved with faster defibrillation ( 10 min: reference). Bystanders and first responders were mainly responsible for defibrillation within 5 min, independent of location of arrest. Bystanders initiated CPR in half of the cardiac arrest cases but only defibrillated a minority of those. Timely defibrillation and defibrillation by bystanders and/or first responders were strongly associated with increased survival. Strategic efforts to increase bystander and first-responder defibrillation are warranted to increase survival after out-of-hospital cardiac arrest. Copyright © 2015 Elsevier Ireland Ltd.

    To compare patient outcomes of restrictive versus liberal blood transfusion strategies in patients with cardiovascular disease not undergoing cardiac surgery. Systematic review and meta-analysis. Randomised controlled trials involving a threshold for red blood cell transfusion in hospital. We searched (to 2 November 2015) CENTRAL, Medline, Embase, CINAHL, PubMed, LILACS, NHSBT Transfusion Evidence Library, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, ISRCTN Register, and EU Clinical Trials Register. Authors were contacted for data whenever possible. Published and unpublished randomised controlled trials comparing a restrictive with liberal transfusion threshold and that included patients with cardiovascular disease. Data extraction was completed in duplicate. Risk of bias was assessed using Cochrane methods. Relative risk ratios with 95% confidence intervals were presented in all meta-analyses. Mantel-Haenszel random effects models were used to pool risk ratios. 30 day mortality, and cardiovascular events. 41 trials were identified; of these, seven included data on patients with cardiovascular disease. Data from a further four trials enrolling patients with cardiovascular disease were obtained from the authors. In total, 11 trials enrolling patients with cardiovascular disease (n=3033) were included for meta-analysis (restrictive transfusion, n=1514 patients; liberal transfusion, n=1519). The pooled risk ratio for the association between transfusion thresholds and 30 day mortality was 1.15 (95% confidence interval 0.88 to 1.50, P=0.50), with little heterogeneity (I(2)=14%). The risk of acute coronary syndrome in patients managed with restrictive compared with liberal transfusion was increased (nine trials; risk ratio 1.78, 95% confidence interval 1.18 to 2.70, P=0.01, I(2)=0%). The results show that it may not be safe to use a restrictive transfusion threshold of less than 80 g/L in patients with ongoing acute coronary syndrome or

    Introduction Anorexia nervosa is an eating disorder, which is associated with many different medical complications as a result of the weight loss and malnutrition that characterise this illness. It has the highest mortality rate of any psychiatric disorder. A large portion of deaths are attributable to the cardiac abnormalities that ensue as a result of the malnutrition associated with anorexia nervosa. In this review, the cardiac complications of anorexia nervosa will be discussed. A comprehensive literature review on cardiac changes in anorexia nervosa was carried out. There are structural, functional, and rhythm-type changes that occur in patients with anorexia nervosa. These become progressively significant as ongoing weight loss occurs. Cardiac changes are inherent to anorexia nervosa and they become more life-threatening and serious as the anorexia nervosa becomes increasingly severe. Weight restoration and attention to these cardiac changes are crucial for a successful treatment outcome.

Burns School of Medicine, University of Hawaii at Mānoa, 3Tissue Genesis, Inc., Honolulu, HI, USA Background: Adipose tissue is an abundant and potent source of adult stem cells for transplant therapy. In this study, we present our findings on the potential application of adipose-derived stem cells (ASCs as well as induced cardiac-like progenitors (iCPs derived from ASCs for the treatment of myocardial infarction. Methods and results: Human bone marrow (BM-derived stem cells, ASCs, and iCPs generated from ASCs using three defined cardiac lineage transcription factors were assessed in an immune-compromised mouse myocardial infarction model. Analysis of iCP prior to transplant confirmed changes in gene and protein expression consistent with a cardiac phenotype. Endpoint analysis was performed 1 month posttransplant. Significantly increased endpoint fractional shortening, as well as reduction in the infarct area at risk, was observed in recipients of iCPs as compared to the other recipient cohorts. Both recipients of iCPs and ASCs presented higher myocardial capillary densities than either recipients of BM-derived stem cells or the control cohort. Furthermore, mice receiving iCPs had a significantly higher cardiac retention of transplanted cells than all other groups. Conclusion: Overall, iCPs generated from ASCs outperform BM-derived stem cells and ASCs in facilitating recovery from induced myocardial infarction in mice.

A 33-year-old woman was treated for cough, fever and chest pain. Cardiac echocardiograpic examination revealed a round tumor (5.8 x 4 cm in the right ventricular free wall and two smaller cysts behind that tumor. There were cysts in right atrial wall and tricuspidal valve as well. Serologic tests for hydatidosis were positive. Computed tomography finding was consistent with diagnosis of hydatid cyst in lungs and right hylar part. Surgical treatment was rejected due to great risk of cardiac perforation. Medical treatment with albendazole was unsuccessful and the patient died due to systemic hydatid involvement of the lungs, liver and central nervous system.

    PREREQUIS: Amyloidosis is a rare infiltrative disease characterized by multiple clinical features. Various organs are involved and the cardiovascular system is a common target of amyloidosis. Cardiac involvement may occur with or without clinical manifestations and is considered as a major prognostic factor. To analyze the clinical features of cardiac involvement, to review actual knowledgement concerning echocardiographic diagnostic and to evaluate recent advances in treatment of the disease. An electronic search of the relevant literature was carried out using Medline and Pubmed. Keys words used for the final search were amyloidosis, cardiopathy and echocardiography. We considered for analysis reviews, studies and articles between 1990 and 2007. Amyloidosis represents 5 to 10% of non ischemic cardiomyoparhies. Cardiac involvement is the first cause of restrictive cardiomyopathy witch must be evoked in front of every inexplained cardiopathy after the age of forty. The amyloid nature of cardiopathy is suggered if some manifestations were associated as a peripheric neuropathy, a carpal tunnel sydrome and proteinuria > 3g/day. Echocardiography shows dilated atria, a granular sparkling appearance of myocardium, diastolic dysfunction and thickened left ventricle contrasting with a low electric voltage. The proof of amyloidosis is brought by an extra-cardiac biopsy, the indications of endomyocardial biopsy are very limited. The identification of the amyloid nature of cardiopathy has an direct therapeutic implication: it indicates the use of digitalis, calcium channel blockers and beta-blockers. Today the treatment of amyloidosis remains very unsatisfactory especially in the cardiac involvement. An early diagnosis before the cardiac damage may facilitate therapy and improve prognosis.

    2013-09-01

    Full Text Available Objectives: To explore patients’ views on the EuroQol-5D and Coronary Revascularisation Outcome Questionnaire, tools currently used for collecting patient-reported outcome measures in the English National Health Service. The key questions were as follows: (1 whether patients consider them sensitive enough to detect change in their health after cardiovascular disease interventions and (2 whether they consider the health-related quality-of-life questions as meaningful. Methods: Data were collected on patients’ views using focus groups. We held four focus groups selecting participants on the basis of their baseline and follow-up EuroQol-5D scores. Data were analysed using framework analysis and grounded theory. Results: Focus group participants confirmed that they had derived substantial health benefits from their cardiac interventions despite the lack of measurable effects on the EuroQol-5D scores. Participants felt that the EuroQol-5D questionnaire was limited because of the following reasons: Their health fluctuates from day to day. They had difficulty assessing their general health status on the visual analogue scale. They felt that the Coronary Revascularisation Outcome Questionnaire was limited because of the following reasons: They did not understand the clinical terms used. The impact of tiredness on their quality of life was not captured. They were unable to distinguish between the effects of their heart condition and other health issues. Additionally, neither questionnaire considers the adjustments people have made to their domestic arrangements to improve their health-related quality of life. Conclusion: This study provides evidence that the two questionnaires do not capture some aspects of health that patients consider important. Furthermore, the presence of co-morbidities masks the symptoms relating to the heart disease and the effect of their cardiac interventions. Future work on patient-reported outcome measures should consider

    Since December 2009, after breast-conserving surgery for Stage 0-I cancer of the left breast, 21 women with relatively pendulous breasts underwent computed tomography prone and supine simulations. The adjuvant radiotherapy was 50 Gy in 25 fractions to the left breast alone. Four plans-conventional wedged tangents and forward intensity-modulated radiotherapy (fIMRT) in supine and prone positions-were generated. fIMRT generated better homogeneity in both positions. Prone position centralized the breast tissue by gravity and also shortened the breast width which led to better conformity in both planning techniques. Prone fIMRT significantly reduced doses to left lung, Level I and Level II axilla. The mean cardiac doses did not differ between positions. Among the four plans, prone fIMRT produced the best target dosimetry and normal organ sparing. In subgroup analysis, patients with absolute breast depth >7 cm in the prone position or breast depth difference >3 cm between positions had significant cardiac sparing with prone fIMRT. Sixteen patients with significant cardiac sparing in prone position were treated using prone fIMRT and the others using supine fIMRT. All patients received a supine electron tumor bed boost of 10 Gy in 5 fractions. No patients developed Grade 2 or worse acute or late toxicities. There was no difference in the number of segments or beams, monitor units, treatment time, or positioning reproducibility between prone and supine positions. At a median follow-up time of 26.8 months, no locoregional or distant recurrence or death was noted. (author)

    2014-01-01

    Cardiac-specific troponins (Tns) are sensitive and specific markers of myocardial injury that have been shown to be predictive of outcomes in many cardiac and noncardiac conditions. We sought to determine whether normal cardiac Tn concentrations obtained during the first 24 hours following blunt chest trauma would predict good cardiac outcomes. A PubMed/MEDLINE search was performed to identify prospective studies in patients with blunt chest trauma in which serial cardiac TnT or TnI values were measured within 24 hours of admission and clinical outcomes assessed. Ten studies qualified for review. Studies that used the lower reference limit of Tn as the cutoff for cardiac injury showed 100% negative predictive value (NPV) for developing cardiac complications, whereas studies using higher Tn cutoffs showed wider variation in NPV (50%-98%). Cardiac Tn measured within 24 hours using the lower reference limit (LRL) as the cutoff appears to have excellent NPV for clinically significant adverse cardiac events. This could allow for early discharge after a 24-hour observation period in otherwise uncomplicated blunt chest trauma patients and avoid the need for more expensive cardiac imaging and additional resource utilization.

    Full Text Available Prediction of neurological outcome is a crucial part of post cardiac arrest care and prediction in patients remaining unconscious and/or sedated after rewarming from targeted temperature management (TTM remains difficult. Current guidelines suggest the use of serial measurements of the biomarker neuron-specific enolase (NSE in combination with other predictors of outcome in patients admitted after out-of-hospital cardiac arrest (OHCA. This study sought to investigate the ability of NSE to predict poor outcome in patients remaining unconscious at day three after OHCA. In addition, this study sought to investigate if serial NSE measurements add incremental prognostic information compared to a single NSE measurement at 48 hours in this population.This study is a post-hoc sub-study of the TTM trial, randomizing OHCA patients to a course of TTM at either 33°C or 36°C. Patients were included from sites participating in the TTM-trial biobank sub study. NSE was measured at 24, 48 and 72 hours after ROSC and follow-up was concluded after 180 days. The primary end point was poor neurological function or death defined by a cerebral performance category score (CPC-score of 3 to 5.A total of 685 (73% patients participated in the study. At day three after OHCA 63 (9% patients had died and 473 (69% patients were not awake. In these patients, a single NSE measurement at 48 hours predicted poor outcome with an area under the receiver operating characteristics curve (AUC of 0.83. A combination of all three NSE measurements yielded the highest discovered AUC (0.88, p = .0002. Easily applicable combinations of serial NSE measurements did not significantly improve prediction over a single measurement at 48 hours (AUC 0.58-0.84 versus 0.83.NSE is a strong predictor of poor outcome after OHCA in persistently unconscious patients undergoing TTM, and NSE is a promising surrogate marker of outcome in clinical trials. While combinations of serial NSE measurements may

    Complications after cardiac surgery are common and lead to substantial increases in morbidity and mortality. Meta-analyses of small randomized trials have suggested that perioperative statin therapy can prevent some of these complications. We randomly assigned 1922 patients in sinus rhythm who were scheduled for elective cardiac surgery to receive perioperative rosuvastatin (at a dose of 20 mg daily) or placebo. The primary outcomes were postoperative atrial fibrillation within 5 days after surgery, as assessed by Holter electrocardiographic monitoring, and myocardial injury within 120 hours after surgery, as assessed by serial measurements of the cardiac troponin I concentration. Secondary outcomes included major in-hospital adverse events, duration of stay in the hospital and intensive care unit, left ventricular and renal function, and blood biomarkers. The concentrations of low-density lipoprotein cholesterol and C-reactive protein after surgery were lower in patients assigned to rosuvastatin than in those assigned to placebo (PSTICS ClinicalTrials.gov number, NCT01573143.).

    Penetrating cardiac injuries are common in South Africa. Reports describing traumatic lesions to the heart caused by caudo-cranial migration of ingested foreign bodies are however extremely rare. Delayed presentation and intervention are associated with poor outcome in these patients; cardiac tamponade remains the most serious complication. We present the case of a 19 year-old man who sustained a left ventricular injury after intentionally swallowing eight sewing needles. The impacted needle was removed through a median sternotomy and the patient recovered uneventfully.

    Transient thyroid dysfunction occurs in children after cardiopulmonary bypass (CPB). We demonstrated significant benefits of acute postoperative tri-iodothyronine (T3) treatment for recovery and myocardial function. Now we report the long-term neurodevelopment of these children. Twenty-eight children (70% of the original study population) could be recruited for a follow-up examination (median age 10.7 years, range 10-19.6 years) retaining the double-blind, randomized, placebo-controlled protocol. Cognitive function and motor development were tested, as were growth and thyroid and cardiac functions. The median full-scale intelligence quotient of all children was within the reference range and similar in the placebo and T3 groups. Tests for motor and cognitive functions, growth, and thyroid and cardiac functions revealed concurrent results. Overall intellectual development is preserved in adolescents treated with CPB in infancy irrespectively of low postoperative thyroid hormone concentrations. While acute postoperative T3 treatment in children after CPB improves recovery, no significant long-term effects on neurodevelopment could be detected. We therefore speculate that transient postoperative thyroid dysfunction by means of nonthyroidal illness syndrome is predominantly mediated by extranuclear, nongenomic mechanisms and thus acutely affects the cardiovascular system but not the development of the central nervous system mediated by genomic mechanisms. © 2015 S.

    Full Text Available Accurate calculation of ventricular stress and strain is critical for cardiovascular investigations. Sarcomere shortening in active contraction leads to change of ventricular zero-stress configurations during the cardiac cycle. A new model using different zero-load diastole and systole geometries was introduced to provide more accurate cardiac stress/strain calculations with potential to predict post pulmonary valve replacement (PVR surgical outcome.Cardiac magnetic resonance (CMR data were obtained from 16 patients with repaired tetralogy of Fallot prior to and 6 months after pulmonary valve replacement (8 male, 8 female, mean age 34.5 years. Patients were divided into Group 1 (n = 8 with better post PVR outcome and Group 2 (n = 8 with worse post PVR outcome based on their change in RV ejection fraction (EF. CMR-based patient-specific computational RV/LV models using one zero-load geometry (1G model and two zero-load geometries (diastole and systole, 2G model were constructed and RV wall thickness, volume, circumferential and longitudinal curvatures, mechanical stress and strain were obtained for analysis. Pairwise T-test and Linear Mixed Effect (LME model were used to determine if the differences from the 1G and 2G models were statistically significant, with the dependence of the pair-wise observations and the patient-slice clustering effects being taken into consideration. For group comparisons, continuous variables (RV volumes, WT, C- and L- curvatures, and stress and strain values were summarized as mean ± SD and compared between the outcome groups by using an unpaired Student t-test. Logistic regression analysis was used to identify potential morphological and mechanical predictors for post PVR surgical outcome.Based on results from the 16 patients, mean begin-ejection stress and strain from the 2G model were 28% and 40% higher than that from the 1G model, respectively. Using the 2G model results, RV EF changes correlated negatively with

    Cardiac misconceptions are common and may have a detrimental effect on patients. Such misconceptions may be introduced or reinforced by vague and inconsistent advice from healthcare staff and can adversely affect health outcomes. To assess whether level of cardiac misconceptions significantly differs between groups of healthcare staff based on occupation. The 22-item York cardiac beliefs questionnaire (YCBQ) was administered to a convenience sample of healthcare staff (n = 263) in direct contact with cardiac patients. Data was also collected on the occupation of healthcare staff and years worked. Medical staff had the lowest mean score (17.5, CI 15.6-19.4), indicating fewest misconceptions, and unqualified healthcare workers had the highest mean score (32.1, CI 28.4-35.7). Analysis by ANOVA indicated differences between staff groups to be statistically significant (F = 17.66, p misconception score (Pearson's r = - 0.243, p misconceptions in different groups of healthcare staff. Education to correct cardiac misconceptions should be particularly targeted at unqualified healthcare staff. The importance of maintaining appropriate ratios of qualified to unqualified healthcare staff in the care of cardiac patients is supported by this study.

    Full Text Available Background: Recent review of older (≥45-years-old patients admitted to our trauma center showed that more than one-third were using neuro-psychiatric medications (NPMs prior to their injury-related admission. Previously published data suggests that use of NPMs may increase patients′ risk and severity of injury. We sought to examine the impact of pre-injury NPM use on older trauma patients′ morbidity and mortality. Materials and Methods: Retrospective record review included medication regimen characteristics and NPM use (antidepressants-AD, antipsychotics-AP, anxiolytics-AA. Hospital morbidity, mortality, and 90-day survival were examined. Comparisons included regimens involving NPMs, further focusing on their interactions with various cardiac medications (beta blocker - BB; angiotensin-converting enzyme inhibitor/angiotensin receptor blocker - ACE/ARB; calcium channel blocker - CCB. Results: 712 patient records were reviewed (399 males, mean age 63.5 years, median ISS 8. 245 patients were taking at least 1 NPM: AD (158, AP (35, or AA (108 before injury. There was no effect of NPM monotherapy on hospital mortality. Patients taking ≥3 NPMs had significantly lower 90-day survival compared to patients taking ≤2 NPMs (81% for 3 or more NPMs, 95% for no NPMs, and 89% 1-2 NPMs, P < 0.01. Several AD-cardiac medication (CM combinations were associated with increased mortality compared to monotherapy with either agent (BB-AD 14.7% mortality versus 7.0% for AD monotherapy or 4.8% BB monotherapy, P < 0.05. Combinations of ACE/ARB-AA were associated with increased mortality compared to ACE/ARB monotherapy (11.5% vs 4.9, P = 0.04. Finally, ACE/ARB-AD co-administration had higher mortality than ACE/ARB monotherapy (13.5% vs 4.9%, P = 0.01. Conclusions: Large proportion of older trauma patients was using pre-injury NPMs. Several regimens involving NPMs and CMs were associated with increased in-hospital mortality.

    2015-10-01

    Full Text Available There is increasing evidence that a low vitamin D status may be an important and hitherto neglected factor of cardiovascular disease. This review is an overview of the current body of literature, and presents evidence of the mechanisms through which vitamin D deficiency affects the cardiovascular system in general and the heart in particular. Available data indicate that the majority of congestive heart failure patients have 25-hydroxyvitamin D deficiency. Furthermore, the low serum 25-hydroxyvitamin D level has a higher impact on hypertension, coronary artery disease an on the occurrence of relevant cardiac events. A serum 25-hydroxyvitamin D level below 75 nmol/l (30 ng/l is generally regarded as vitamin D insufficiency in both adults and children, while a level below 50 nmol/l (20 ng/l is considered deficiency. Levels below 50 nmol/l (20 ng/l are linked independently to cardiovascular morbidity and mortality.

    The construction of a cardiac pacemaker is described which is characterized by particularly small dimensions, small weight and long life duration. The weight is under 100g, the specific weight under 1.7. Mass inertia forces which occur through acceleration and retardation processes, thus remain below the threshold values, above which one would have to reckon with considerable damaging of the surrounding body tissue. The maintaining of small size and slight weight is achieved by using an oscillator on COSMOS basis, where by considerably lower energy consumption, amongst others the lifetimes of the batteries used - a lithium anode with thionyl chloride electrolyte - is extended to over 5 years. The reliability can be increased by the use of 2 or more batteries. The designed dimension are 20x60x60 mm 3 . (ORU/LH) [de

    This prospective, observational study in 988 asymptomatic or symptomatic low-risk patients without prior coronary artery disease was conducted to define the relative value of coronary artery calcium score (CACS), exercise treadmill testing (ETT), and stress myocardial perfusion single-photon emission computed tomography (SPECT) variables in predicting long-term risk stratification. CACS, ETT, and stress myocardial perfusion SPECT results predict patients' outcome. There are currently no data comparing their relative value in long-term risk stratification. Patients were stratified by Framingham risk score (FRS), with a median follow-up of 6.9 years. Cardiac events were defined as a composite of cardiac death, nonfatal myocardial infarction, and the need for coronary revascularization. Most patients (87%) were considered appropriate candidates for functional testing as defined by current appropriate use criteria. The long-term cardiac event rate was 11.2% (1.6% per year). Multivariate risk predictors in all patients and in the appropriate use cohort were abnormal SPECT (hazard ratio [HR]: 1.83 and 1.99), ETT ischemia (HR: 1.70 and 1.76), decreasing exercise capacity (HR: 1.11 and 1.17), decreasing Duke treadmill score (HR: 1.07 for both), and CACS severity (HR: 1.29 for both), respectively. Throughout the 10-year follow-up, CACS improved risk prediction, with event rates ranging from 0.6% per year (CACS ≤10) to 3.7% per year (CACS >400) (p risk prediction in all patients, in the appropriate use cohort and among those with low-risk ETT and SPECT results (all, p risk stratification beyond FRS, ETT, and SPECT results across the spectrum of clinical risk and importantly even among those who are currently considered appropriate candidates for functional testing or have low-risk functional test results.

    We hypothesized that a targeted temperature of 33 °C as compared to that of 36 °C would increase survival and reduce the severity of circulatory shock in patients with shock on admission after out-of-hospital cardiac arrest (OHCA). The recently published Target Temperature Management trial (TTM-trial) randomized 939 OHCA patients with no difference in outcome between groups and no difference in mortality at the end of the trial in a predefined subgroup of patients with shock at admission. Shock was defined as a systolic blood pressure of 30 min or the need of supportive measures to maintain a blood pressure ≥90 mmHg and/or clinical signs of end-organ hypoperfusion. In this post hoc analysis reported here, we further analyzed the 139 patients with shock at admission; all had been randomized to receive intervention at 33 °C (TTM33; n = 71) or 36 °C (TTM36; n = 68). Primary outcome was 180-day mortality. Secondary outcomes were intensive care unit (ICU) and 30-day mortality, severity of circulatory shock assessed by mean arterial pressure, serum lactate, fluid balance and the extended Sequential Organ Failure assessment (SOFA) score. There was no significance difference between targeted temperature management at 33 °C or 36 °C on 180-day mortality [log-rank test, p = 0.17, hazard ratio 1.33, 95 % confidence interval (CI) 0.88-1.98] or ICU mortality (61 vs. 44 %, p = 0.06; relative risk 1.37, 95 % CI 0.99-1.91).

    In people with coronary artery disease, does an expanded cardiac rehabilitation program reduce cardiac deaths, myocardial infarctions, and hospital admissions due to cardiovascular disease? Randomised, controlled trial with intention-to-treat analysis. A University hospital in Sweden. People aged less than 75 years who had had a recent myocardial infarction or coronary artery bypass grafts were eligible to participate. Severe co-morbidities were exclusion criteria. Randomisation of 224 participants allocated 111 to undergo expanded cardiac rehabilitation and 113 to a control group. Both groups received standard cardiac rehabilitation, including physical training, education, group and individual counselling, and support to cease smoking. All participants received appropriate preventive medications. In addition, the intervention group received 20 group sessions of stress management, 3 sessions of cooking and diet counselling by a dietician, and a 5-day stay at a 'patient hotel' with several activities including physical training and information. Although other outcomes were reported at the conclusion of 1-year follow-up, the outcomes at the 5-year follow-up were rates of cardiac events: cardiovascular death, acute myocardial infarction, and readmission to a hospital due to other cardiovascular causes. All participants were followed up via national registers of health and mortality. During the 5-year follow-up, 53 (48%) participants in the expanded cardiac rehabilitation group and 68 (60%) participants in the control group had a cardiac event (hazard ratio 0.69, 95% CI 0.48 to 0.99). This difference was mainly due to only 12 (11%) participants having non-fatal myocardial infarctions in the treatment group versus 23 (20%) in the control group (hazard ratio 0.47, 95% CI 0.21 to 0.97). The number of hospitalisations and the number of days of hospitalisation were both significantly fewer in the treatment group than in the control group. Expanded cardiac rehabilitation

    Inhalation of hydrogen cyanide from smoke in structural fires is common, but cardiovascular function in these patients is poorly documented. The objective was to study the cardiac complications of cyanide poisoning in patients who received early administration of a cyanide antidote, hydroxocobalamin (Cyanokit; Merck KGaA, Darmstadt, Germany [in the United States, marketed by Meridian Medical Technologies, Bristol, TN]). The medical records of 161 fire survivors with suspected or confirmed cyanide poisoning were reviewed in an open, multicenter, retrospective review of cases from the Emergency Medical Assistance Unit (Service d'Aide Médical d'Urgence) in France. Cardiac arrest (61/161, 58 asystole, 3 ventricular fibrillation), cardiac rhythm disorders (57/161, 56 supraventricular tachycardia), repolarization disorders (12/161), and intracardiac conduction disorders (5/161) were observed. Of the total 161 patients studied, 26 displayed no cardiac disorder. All patients were given an initial dose of 5 g of hydroxocobalamin. Non-responders received a second dose of 5 g of hydroxocobalamin. Of the patients initially in cardiac arrest, 30 died at the scene, 24 died in hospital, and 5 survived without cardiovascular sequelae. Cardiac disorders improved with increasing doses of hydroxocobalamin, and higher doses of the antidote seem to be associated with a superior outcome in patients with initial cardiac arrest. Cardiac complications are common in cyanide poisoning in fire survivors. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    To describe temporal trends in the time interval between first and second attempts at defibrillation and the association between this time interval and outcomes in patients with persistent ventricular tachycardia or ventricular fibrillation (VT/VF) arrest in hospital. Retrospective cohort study 172 hospitals in the United States participating in the Get With The Guidelines-Resuscitation registry, 2004-12. Adults who received a second defibrillation attempt for persistent VT/VF arrest within three minutes of a first attempt. Second defibrillation attempts categorized as early (time interval of up to and including one minute between first and second defibrillation attempts) or deferred (time interval of more than one minute between first and second defibrillation attempts). Survival to hospital discharge. Among 2733 patients with persistent VT/VF after the first defibrillation attempt, 1121 (41%) received a deferred second attempt. Deferred second defibrillation for persistent VT/VF increased from 26% in 2004 to 57% in 2012 (Pdefibrillation, unadjusted patient outcomes were significantly worse with deferred second defibrillation (57.4% v 62.5% for return of spontaneous circulation, 38.4% v 43.6% for survival to 24 hours, and 24.7% v 30.8% for survival to hospital discharge; Pdefibrillation was not associated with survival to hospital discharge (propensity weighting adjusted risk ratio 0.89, 95% confidence interval 0.78 to 1.01; P=0.08; hierarchical regression adjusted 0.92, 0.83 to 1.02; P=0.1). Since 2004, the use of deferred second defibrillation for persistent VT/VF in hospital has doubled. Deferred second defibrillation was not associated with improved survival.

    In response to urban-rural disparities in healthcare resources, China recently launched a healthcare reform with a focus on improving rural care during the past decade. However, nationally representative studies comparing medical care and patient outcomes between urban and rural areas in China during this period are not available. We created a nationally representative sample of patients in China admitted for ST-segment-elevation myocardial infarction in 2001, 2006, and 2011, using a 2-stage random sampling design in 2 urban and 3 rural strata. In China, evidence-based treatments were provided less often in 2001 in rural hospitals, which had lower volume and less availability of advanced cardiac facilities. However, these differences diminished by 2011 for reperfusion therapy (54% in urban versus 57% in rural; P =0.1) and reversed for angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (66% versus 68%; P =0.04) and early β-blockers (56% versus 60%; P =0.01). The risk-adjusted rate of in-hospital death or withdrawal from treatment was not significantly different between urban and rural hospitals in any study year, with an adjusted odds ratio of 1.13 (0.77-1.65) in 2001, 0.99 (0.77-1.27) in 2006, and 0.94 (0.74-1.19) in 2011. Although urban-rural disparities in evidence-based treatment for myocardial infarction in China have largely been eliminated, substantial gaps in quality of care persist in both settings. In addition, urban hospitals providing more resource-intensive care did not achieve better outcomes. URL: https://www.clinicaltrials.gov.

    Prognosis of patients with light-chain cardiac amyloidosis (AL-CA) is poor. Speckle tracking imaging (STI) derived longitudinal deformation parameters and Doppler-derived left ventricular (LV) Tei index are valuable predictors of outcome in patients with AL-CA. We estimated the prognostic utility of Tei index and deformation parameters in 58 comprehensively phenotyped patients with AL-CA after a median follow-up of 365 days (quartiles 121, 365 days). The primary end point was all-cause mortality. 19 (33%) patients died during follow-up. Tei index (0.89 ± 0.29 vs. 0.61 ± 0.16, p < 0.001) and E to global early diastolic strain rate ratio (E/GLSR dias ) were higher while global longitudinal systolic strain (GLS sys ) was lower in non-survivors than in survivors (all p < 0.05). Tei index, NYHA functional class, GLS sys and E/GLSR dias were independent predictors of all-cause mortality risk, and Tei index ≥0.9 (HR 7.01, 95% CI 2.43-20.21, p < 0.001) was the best predictor of poor outcome. Combining Tei index and GLS sys yielded the best results on predicting death within 1 year (100% with Tei index ≥0.9 and GLS sys ≤13%) or survival (95% with Tei index ≤0.9 and GLS sys ≥13%). We conclude that 1-year mortality risk in AL-CA patients can be reliably predicted using Tei index or deformation parameters, with combined analysis offering best performance.

    Pulseless electrical activity occurs when organised or semi-organised electrical activity of the heart persists but the product of systemic vascular resistance and the increase in systemic arterial flow generated by the ejection of the left venticular stroke volume is not sufficient to produce a clinically detectable pulse. Pulseless electrical activity encompasses a very heterogeneous variety of severe circulatory shock states ranging in severity from pseudo-cardiac arrest to effective cardiac arrest. Outcomes of cardiopulmonary resuscitation for pulseless electrical activity are generally poor. Impairment of cardiac filling is the limiting factor to cardiac output in many scenarios of pulseless electrical activity, including extreme vasodilatory shock states. There is no evidence that external cardiac compression can increase cardiac output when impaired cardiac filling is the limiting factor to cardiac output. If impaired cardiac filling is the limiting factor to cardiac output and the heart is effectively ejecting all the blood returning to it, then external cardiac compression can only increase cardiac output if it increases venous return and cardiac filling. Repeated cardiac compression asynchronous with the patient\\'s cardiac cycle and raised mean intrathoracic pressure due to chest compression can be expected to reduce rather than to increase cardiac filling and therefore to reduce rather than to increase cardiac output in such circumstances. The hypothesis is proposed that the performance of external cardiac compression will have zero or negative effect on cardiac output in pulseless electrical activity when impaired cardiac filling is the limiting factor to cardiac output. External cardiac compression may be both directly and indirectly harmful to significant sub-groups of patients with pulseless electrical activity. We have neither evidence nor theory to provide comfort that external cardiac compression is not harmful in many scenarios of pulseless

    2012-04-01

    Following a perinatal hypoxic-ischaemic insult, term infants commonly develop cardiovascular dysfunction. Troponin-T, troponin-I and brain natriuretic peptide are sensitive indicators of myocardial compromise. The long-term effects of cardiovascular dysfunction on neurodevelopmental outcome following perinatal hypoxic ischaemia remain controversial. Follow-up studies are warranted to ensure optimal cardiac function in adulthood. CONCLUSION: Cardiac biomarkers may improve the diagnosis of myocardial injury, help guide management, estimate mortality risk and may also aid in longterm neurodevelopmental outcome prediction following neonatal hypoxic-ischaemia.

    Implantable cardioverter-defibrillators (ICDs) reduce the risk of death in patients with left ventricular dysfunction. Little is known regarding the benefit of this therapy in African Americans (AAs). The purpose of this study was to determine the association between AA race and outcomes in a cohort of primary prevention ICD patients. We conducted a prospective cohort study of patients with systolic heart failure who underwent ICD implantation for primary prevention of sudden cardiac death. The primary end-point was appropriate ICD shock defined as a shock for rapid ventricular tachyarrhythmias. The secondary end-point was all-cause mortality. There were 1189 patients (447 AAs and 712 non-AAs) enrolled. Over a median follow-up of 5.1 years, a total of 137 patients experienced an appropriate ICD shock, and 343 died (294 of whom died without receiving an appropriate ICD shock). The multivariate adjusted hazard ratio (95% confidence interval) comparing AAs vs non-AAs were 1.24 (0.96-1.59) for all-cause mortality, 1.33 (1.02, 1.74) for all-cause mortality without receiving appropriate ICD shock, and 0.78 (0.51, 1.19) for appropriate ICD shock. Ejection fraction, diabetes, and hypertension appeared to explain 24.1% (10.1%-69.5%), 18.7% (5.3%-58.0%), and 13.6% (3.8%-53.6%) of the excess risk of mortality in AAs, with a large proportion of the mortality difference remaining unexplained. In patients with primary prevention ICDs, AAs had an increased risk of dying without receiving an appropriate ICD shock compared to non-AAs. Copyright © 2014 Heart Rhythm Society.

    There are several theoretic advantages to synchronizing positive pressure breaths with the cardiac cycle, including the potential for improving distribution of pulmonary and myocardial blood flow and enhancing cardiac output. We evaluated the effects of synchronizing respiration to the cardiac cycle using a programmable ventilator and electron beam CT (EBCT) scanning. The hearts of anesthetized dogs were imaged during cardiac gated respiration with a 50msec scan aperture. Multislice, short axis, dynamic image data sets spanning the apex to base of the left ventricle were evaluated to determine the volume of the left ventricular chamber at end-diastole and end-systole during apnea, systolic and diastolic cardiac gating. We observed an increase in cardiac output of up to 30% with inspiration gated to the systolic phase of the cardiac cycle in a nonfailing model of the heart.

    The 2014 American College of Cardiology/American Heart Association Perioperative Guidelines suggest using the Revised Cardiac Risk Index, myocardial infarction or cardiac arrest, or American College of Surgeons-National Surgical Quality Improvement Program calculators for combined patient-surgical risk assessment. There are no published data comparing their performance. This study compared these risk calculators and a reconstructed Revised Cardiac Risk Index in predicting postoperative cardiac complications, both during hospitalization and 30 days after operation, in a patient cohort who underwent select surgical procedures in various risk categories. Cardiac complications occurred in 14 of 663 patients (2.1%), of which 11 occurred during hospitalization. Only 3 of 663 patients (0.45%) had a myocardial infarction or cardiac arrest. Because these calculators used different risk factors, different outcomes, and different durations of observation, a true direct comparison is not possible. We found that all 4 risk calculators performed well in the setting they were originally studied but were less accurate when applied in a different manner. In conclusion, all calculators were useful in defining low-risk patients in whom further cardiac testing was unnecessary, and the myocardial infarction or cardiac arrest may be the most reliable in selecting higher risk patients.

    Postoperative non-cardiac complication rates are as high as 11-28% after high-risk abdominal procedures. Emerging evidence indicates that postoperative cardiac troponin T elevations are associated with adverse outcome in non-cardiac surgery. The aim of this study was to determine the relationship between postoperative high-sensitive cardiac troponin T elevations and non-cardiac complications in patients after major abdominal surgery. This prospective observational single-centre cohort study included patients at risk for coronary artery disease undergoing elective major abdominal surgery. Cardiac troponin was measured before surgery and at day 1, 3, and 7. Multivariable logistic regression analysis was performed to examine the adjusted association for different cut-off concentrations of postoperative myocardial injury and non-cardiac outcome. In 203 patients, 690 high-sensitive cardiac troponin T measurements were performed. Fifty-three patients (26%) had a non-cardiac complication within 30 days after surgery. Hospital mortality was 4% (8/203). An increase in cardiac troponin T concentration ≥100% compared with baseline was a superior independent predictor of non-cardiac postoperative clinical complications (adjusted odds ratio 4.3, 95% confidence interval 1.8-10.1, Phigh-sensitive cardiac troponin T increase ≥100% is a strong predictor of non-cardiac 30 day complications, increased hospital stay and hospital mortality in patients undergoing major abdominal surgery.

  6. Stimulating endogenous cardiac regeneration

    Directory of Open Access Journals (Sweden)

    Amanda eFinan

    2015-09-01

    Full Text Available The healthy adult heart has a low turnover of cardiac myocytes. The renewal capacity, however, is augmented after cardiac injury. Participants in cardiac regeneration include cardiac myocytes themselves, cardiac progenitor cells, and peripheral stem cells, particularly from the bone marrow compartment. Cardiac progenitor cells and bone marrow stem cells are augmented after cardiac injury, migrate to the myocardium, and support regeneration. Depletion studies of these populations have demonstrated their necessary role in cardiac repair. However, the potential of these cells to completely regenerate the heart is limited. Efforts are now being focused on ways to augment these natural pathways to improve cardiac healing, primarily after ischemic injury but in other cardiac pathologies as well. Cell and gene therapy or pharmacological interventions are proposed mechanisms. Cell therapy has demonstrated modest results and has passed into clinical trials. However, the beneficial effects of cell therapy have primarily been their ability to produce paracrine effects on the cardiac tissue and recruit endogenous stem cell populations as opposed to direct cardiac regeneration. Gene therapy efforts have focused on prolonging or reactivating natural signaling pathways. Positive results have been demonstrated to activate the endogenous stem cell populations and are currently being tested in clinical trials. A potential new avenue may be to refine pharmacological treatments that are currently in place in the clinic. Evidence is mounting that drugs such as statins or beta blockers may alter endogenous stem cell activity. Understanding the effects of these drugs on stem cell repair while keeping in mind their primary function may strike a balance in myocardial healing. To maximize endogenous cardiac regeneration,a combination of these approaches couldameliorate the overall repair process to incorporate the participation ofmultiple cell players.

    Cardiac myxoma in pregnancy is rare and the clinical characteristics of this entity have been insufficiently elucidated. This article aims to describe the treatment options and the risk factors responsible for the maternal and feto-neonatal prognoses. A comprehensive search of the literature of cardiac myxoma in pregnancy was conducted and 44 articles with 51 patients were included in the present review. Transthoracic echocardiography was the most common diagnostic tool for the diagnosis of cardiac myxoma during pregnancy. Cardiac myxoma resection was performed in 95.9% (47/49); while no surgical resection was performed in 4.1% (2/49) patients (P=0.000). More patients had an isolated cardiac myxoma resection in comparison to those with a concurrent or staged additional cardiac operation [87.2% (41/47) vs. 12.8% (6/47), P=0.000]. A voluntary termination of the pregnancy was done in 7 (13.7%) cases. In the remaining 31 (60.8%) pregnant patients, cesarean section was the most common delivery mode representing 61.3% and vaginal delivery was more common accounting for 19.4%. Cardiac surgery was performed in the first, second and third trimester in 5 (13.9%), 14 (38.9%) and 17 (47.2%) patients, respectively. No patients died. In the delivery group, 20 (76.9%) neonates were event-free survivals, 4 (15.4%) were complicated and 2 (7.7%) died. Neonatal prognoses did not differ between the delivery modes, treatment options, timing of cardiac surgery and sequence of cardiac myxoma resection in relation to delivery. The diagnosis of cardiac myxoma in pregnancy is important. Surgical treatment of cardiac myxoma in the pregnant patients has brought about favorable maternal and feto-neonatal outcomes in the delivery group, which might be attributable to the shorter operation duration and non-emergency nature of the surgical intervention. Proper timing of cardiac surgery and improved cardiopulmonary bypass conditions may result in even better maternal and feto-neonatal survivals.

In the remaining 31 (60.8% pregnant patients, cesarean section was the most common delivery mode representing 61.3% and vaginal delivery was more common accounting for 19.4%. Cardiac surgery was performed in the first, second and third trimester in 5 (13.9%, 14 (38.9% and 17 (47.2% patients, respectively. No patients died. In the delivery group, 20 (76.9% neonates were event-free survivals, 4 (15.4% were complicated and 2 (7.7% died. Neonatal prognoses did not differ between the delivery modes, treatment options, timing of cardiac surgery and sequence of cardiac myxoma resection in relation to delivery.Conclusion:The diagnosis of cardiac myxoma in pregnancy is important. Surgical treatment of cardiac myxoma in the pregnant patients has brought about favorable maternal and feto-neonatal outcomes in the delivery group, which might be attributable to the shorter operation duration and non-emergency nature of the surgical intervention. Proper timing of cardiac surgery and improved cardiopulmonary bypass conditions may result in

    Cardiac sodium channel are protein complexes that are expressed in the sarcolemma of cardiomyocytes to carry a large inward depolarizing current (INa) during phase 0 of the cardiac action potential. The importance of INa for normal cardiac electrical activity is reflected by the high incidence of arrhythmias in cardiac sodium channelopathies, i.e., arrhythmogenic diseases in patients with mutations in SCN5A, the gene responsible for the pore-forming ion-conducting alpha-subunit, or in genes that encode the ancillary beta-subunits or regulatory proteins of the cardiac sodium channel. While clinical and genetic studies have laid the foundation for our understanding of cardiac sodium channelopathies by establishing links between arrhythmogenic diseases and mutations in genes that encode various subunits of the cardiac sodium channel, biophysical studies (particularly in heterologous expression systems and transgenic mouse models) have provided insights into the mechanisms by which INa dysfunction causes disease in such channelopathies. It is now recognized that mutations that increase INa delay cardiac repolarization, prolong action potential duration, and cause long QT syndrome, while mutations that reduce INa decrease cardiac excitability, reduce electrical conduction velocity, and induce Brugada syndrome, progressive cardiac conduction disease, sick sinus syndrome, or combinations thereof. Recently, mutation-induced INa dysfunction was also linked to dilated cardiomyopathy, atrial fibrillation, and sudden infant death syndrome. This review describes the structure and function of the cardiac sodium channel and its various subunits, summarizes major cardiac sodium channelopathies and the current knowledge concerning their genetic background and underlying molecular mechanisms, and discusses recent advances in the discovery of mutation-specific therapies in the management of these channelopathies.

    Restrictive cardiomyopathy (RCM) is a specific group of heart muscle disorders characterized by inadequate ventricular relaxation during diastole. This leads to diastolic dysfunction with relative preservation of systolic function. Although short axis systolic function is usually preserved in RCM, the long axis systolic function may be severely impaired. Confirmation of diagnosis and information regarding aetiology, extent of myocardial damage, and response to treatment requires imaging. Importantly, differentiation from constrictive pericarditis (CCP) is needed, as only the latter is managed surgically. Echocardiography is the initial cardiac imaging technique but cannot reliably suggest a tissue diagnosis; although recent advances, especially tissue Doppler imaging and spectral tracking, have improved its ability to differentiate RCM from CCP. Cardiac catheterization is the reference standard, but is invasive, two-dimensional, and does not aid myocardial characterization. Cardiac magnetic resonance (CMR) is a versatile technique providing anatomical, morphological and functional information. In recent years, it has been shown to provide important information regarding disease mechanisms, and also been found useful to guide treatment, assess its outcome and predict patient prognosis. This review describes the CMR features of RCM, appearances in various diseases, its overall role in patient management, and how it compares with other imaging techniques.

    Many patients experience the 'cardiac blues' at the time of an acute cardiac event, and one in five go on to develop severe depression. These emotional responses often go undetected and unacknowledged. We initiated the 'Cardiac Blues Project' in order to help support patients' emotional recovery. As part of the project, we developed online training in order to support health professionals in the identification and management of the cardiac blues and depression. The aim of this study was to assess the acceptability of the training and its impacts on health professionals' self-efficacy. In July 2014, a 'cardiac blues' pack of patient resources, including access to health professional online training, was mailed to 606 centres across Australia. In the first 3 months after distribution, 140 health professionals registered to undertake the online training and participated in the present study. Participants provided information via a six-item pre- and post-training self-efficacy scale and on 10 post-training acceptability items. Health professionals' self-efficacy improved significantly after undertaking the online training across the six domains assessed and for the total score. Acceptability of the training was high across all 10 items assessed. Ratings of usefulness of the training in clinical practice were particularly favourable amongst those who worked directly with cardiac patients. The health professional training significantly improves health professionals' confidence in identifying and managing the 'cardiac blues' and depression. Monitoring of uptake is ongoing and future studies will investigate patient outcomes.

    2015-01-01

    Full Text Available Sudden cardiac death is one of the most common cause of mortality worldwide. Despite significant advances in the medical science, there is little improvement in the sudden cardiac death related mortality. Coronary artery disease is the most common etiology behind sudden cardiac death, in the above 40 years population. Even in the apparently healthy population, there is a small percentage of patients dying from sudden cardiac death. Given the large denominator, this small percentage contributes to the largest burden of sudden cardiac death. Identification of this at risk group among the apparently healthy individual is a great challenge for the medical fraternity. This article looks into the causes and methods of preventing SCD and at some of the Indian data. Details of Brugada syndrome, Long QT syndrome, Genetics of SCD are discussed. Recent guidelines on many of these causes are summarised.

    The objectives of this review are to describe the education and critical thinking skills that characterize pediatric critical care nursing and how these skills impact patient care and outcomes in pediatric cardiac critical care. MEDLINE and PubMed. Pediatric cardiac critical care nurses manage complex and vulnerable patients requiring various levels of support. Effective care of these patients requires knowledge about the complex anatomy and physiology associated with congenital and acquired heart disease, as well as the effects of mechanical ventilation, mechanical circulatory support, and vasoactive medications. Strong physical examination skills, accurate interpretation of hemodynamic and laboratory data, active participation in bedside rounds, excellent communication skills, meticulous care of invasive monitoring catheters and tubes, and compassionate support of families are among the skills that distinguish a cardiac critical care nurse.

    'Neonatal' lupus erythematosus (NLE) describes a clinical spectrum of cardiac and non-cardiac abnormalities observed in neonates and foetuses whose mothers have the auto-antibodies anti-SSA/Ro (anti-Ro) and anti-SSB/La (anti-La). Of the cardiac abnormalities, congenital AVB is the most common cardiovascular abnormality found in affected foetuses and infants. Many other cardiovascular manifestations of NLE have been more recently recognized including atrial and ventricular arrhythmias and other conduction abnormalities, myocarditis, cardiomyopathy often with endocardiofibroelastosis and structural heart disease, particularly valvar lesions. In this report, the spectrum of cardiovascular manifestations observed in foetuses and infants with NLE are reviewed and the pathogenesis, diagnosis and clinical outcomes are briefly discussed.

    Full Text Available Extracorporeal Life Support (ECLS is a valuable tool in the management of neonates and older children with severe cardiac or respiratory failure. In this review, we focus on ECLS when used for neonatal and pediatric cardiac disease. Strict selection of patients and timely deployment are necessary to optimize outcomes. Although every attempt should be made to deploy ECLS urgently rather than emergently, extracorporeal cardiopulmonary resuscitation (ECPR is being increasingly used and reasonable survival rates have been achieved after initiation of ECLS during active compressions of the chest following in-hospital cardiac arrest. Contraindications to ECLS are falling over time, although lethal chromosomal abnormalities, severe irreversible brain injury, and extremely low gestational age and weight (<32 weeks gestation or <1.5 kg remain firm contraindications.

    To address the need for personalized prevention, we conducted a subject-level meta-analysis within the framework of the Heart "OMics" in AGEing (HOMAGE) study to develop a risk prediction model for heart failure (HF) based on routinely available clinical measurements. Three studies with elderly persons (Health Aging and Body Composition [Health ABC], Valutazione della PREvalenza di DIsfunzione Cardiaca asinTOmatica e di scompenso cardiaco [PREDICTOR], and Prospective Study of Pravastatin in the Elderly at Risk [PROSPER]) were included to develop the HF risk function, while a fourth study (Anglo-Scandinavian Cardiac Outcomes Trial [ASCOT]) was used as a validation cohort. Time-to-event analysis was conducted using the Cox proportional hazard model. Incident HF was defined as HF hospitalization. The Cox regression model was evaluated for its discriminatory performance (area under the receiver operating characteristic curve) and calibration (Grønnesby-Borgan χ 2 statistic). During a follow-up of 3.5 years, 470 of 10 236 elderly persons (mean age, 74.5 years; 51.3% women) developed HF. Higher age, BMI, systolic blood pressure, heart rate, serum creatinine, smoking, diabetes mellitus, history of coronary artery disease, and use of antihypertensive medication were associated with increased HF risk. The area under the receiver operating characteristic curve of the model was 0.71, with a good calibration (χ 2 7.9, P =0.54). A web-based calculator was developed to allow easy calculations of the HF risk. Simple measurements allow reliable estimation of the short-term HF risk in populations and patients. The risk model may aid in risk stratification and future HF prevention strategies. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

    Background and Purpose Visit-to-visit variability in BP is associated with ischemic stroke. We sought to determine whether such variability has a genetic aetiology and whether genetic variants associated with BP variability are also associated with ischemic stroke. Methods A GWAS for loci influencing BP variability was undertaken in 3,802 individuals from the Anglo-Scandinavian Cardiac Outcome Trial (ASCOT) study where long-term visit-to-visit and within visit BP measures were available. Since BP variability is strongly associated with ischemic stroke, we genotyped the sentinel SNP in an independent ischemic stroke population comprising of 8,624 cases and 12,722 controls and in 3,900 additional (Scandinavian) participants from the ASCOT study in order to replicate our findings. Results The ASCOT discovery GWAS identified a cluster of 17 correlated SNPs within the NLGN1 gene (3q26.31) associated with BP variability. The strongest association was with rs976683 (p=1.4×10−8). Conditional analysis on rs976683 provided no evidence of additional independent associations at the locus. Analysis of rs976683 in ischemic stroke patients found no association for overall stroke (OR 1.02; 95% CI 0.97-1.07; p=0.52) or its sub-types: CE (OR 1.07; 95% CI 0.97-1.16; p=0.17), LVD (OR 0.98; 95% 0.89-1.07; p=0.60) and SVD (OR 1.07; 95% CI 0.97-1.17; p=0.19). No evidence for association was found between rs976683 and BP variability in the additional (Scandinavian) ASCOT participants (p=0.18). Conclusions We identified a cluster of SNPs at the NLGN1 locus showing significant association with BP variability. Follow up analyses did not support an association with risk of ischemic stroke and its subtypes. PMID:23929743

    To describe patient characteristics, hospital investigations and interventions and early mortality among patients being hospitalized after out-of-hospital cardiac arrest in two hospitals. Municipality of Göteborg, Sweden. All patients suffering an out-of-hospital cardiac arrest who were successfully resuscitated and admitted to hospital between 1 October 1980 and 31 December 1996. All patients were resuscitated by the same Emergency Medical Service and admitted alive to one of the two city hospitals in Göteborg. Of 579 patients admitted to Sahlgrenska Hospital, 253 (44%) were discharged alive and of 459 patients admitted to Ostra Hospital, 152 (33%) were discharged alive (P percentage of patients admitted to Sahlgrenska Hospital underwent coronary angiography (P < 0.001), electrophysiological testing (P < 0.001), Holter recording (P < 0.001), echocardiography (P = 0.004), percutaneous transluminal coronary angioplasty (PTCA, P = 0.009), implantation of automatic implantable cardioverter defibrillator (AICD, P = 0.03) and exercise stress tests (P = 0.003). Inhabitants in the catchment area of Ostra Hospital had a less favourable socio-economic profile. Survival after out-of-hospital cardiac arrest may be affected by the course of hospital management. Other variables that might influence survival are socio-economic factors and cardiorespiratory status on admission to hospital. Further investigation is called for as more patients are being hospitalised alive after out-of-hospital cardiac arrest.

  12. Imaging for cardiac electrophysiology

    2016-11-01

    Full Text Available Clinical cardiac electrophysiology is the study of the origin and treatment of arrhythmia. There has been considerable recent development in this field, where imaging has had a transformational impact. In this invited review, we offer a global overview of the most important developments in the use of imaging in cardiac electrophysiology. We first describe the radiological imaging modalities involved in cardiac electrophysiology, to assess cardiac anatomy, function and scar. We then introduce an imaging modality with which readers are probably unfamiliar (electroanatomical mapping [EAM], but which is routinely used by electrophysiologists to plan and guide cardiac mapping and cardiac ablation therapy by catheter, a therapy which can reduce or even cure arrhythmia. We identify the limitations of EAM and describe how radiological imaging modalities can complement this technique. We then describe and illustrate how imaging has helped the diagnosis of arrhythmogenic conditions, and how imaging is used to plan and guide clinical cardiac electrophysiologic procedures and assess their results and complications. We focus on the two most common arrhythmias for which imaging has the greatest impact: atrial fibrillation and ventricular tachycardia.

  13. Cardiac tumors: echo assessment

    Directory of Open Access Journals (Sweden)

    Rekha Mankad MD

    2016-12-01

    Full Text Available Cardiac tumors are exceedingly rare (0.001–0.03% in most autopsy series. They can be present anywhere within the heart and can be attached to any surface or be embedded in the myocardium or pericardial space. Signs and symptoms are nonspecific and highly variable related to the localization, size and composition of the cardiac mass. Echocardiography, typically performed for another indication, may be the first imaging modality alerting the clinician to the presence of a cardiac mass. Although echocardiography cannot give the histopathology, certain imaging features and adjunctive tools such as contrast imaging may aid in the differential diagnosis as do the adjunctive clinical data and the following principles: (1 thrombus or vegetations are the most likely etiology, (2 cardiac tumors are mostly secondary and (3 primary cardiac tumors are mostly benign. Although the finding of a cardiac mass on echocardiography may generate confusion, a stepwise approach may serve well practically. Herein, we will review such an approach and the role of echocardiography in the assessment of cardiac masses.

    This study aims to present an updated clinical picture of the infected cardiac myxoma. Revankar & Clark made a systematic review of infected cardiac myxoma based on the literature before 1998. Since then, there has not been any updated information describing its recent changing trends. A comprehensive literature search of infected cardiac myxoma was conducted on MEDLINE, Highwire Press and Google between 1998 and 2014. In comparison with Revankar & Clark's series, the present series disclosed a significantly decreased overall mortality. It is believed that refinement of the prompt diagnosis and timely management (use of sensitive antibiotics and surgical resection of the infected myxoma) have resulted in better outcomes of such patients. The present series of infected cardiac myxoma illustrated some aggravated clinical manifestations (relative more occasions of high-grade fever, multiple embolic events and the presence of refractory microorganisms), which should draw enough attention to careful diagnosis and treatment. In general, the prognosis of infected cardiac myxoma is relatively benign and the long-term survival is always promising.

    The potential for necrotizing enterocolitis (NEC) in neonates requiring cardiac surgery has contributed largely to wide feeding practice variations and a hesitation to initiate enteral feeding during the preoperative period, specifically those patients with hypoplastic left heart syndrome. A retrospective chart review of neonates undergoing cardiac surgery at a single institution between July 2011 and July 2013 was performed. The primary objective of this study was to determine if preoperative feeding was associated with NEC in neonates requiring cardiac surgery. Univariable and multivariable analyses were performed to evaluate the relationship between preoperative feeding and NEC. Secondary outcomes including growth failure, total ventilator days, total length of stay, and tube-assisted feeds at discharge were analyzed. One hundred thirty consecutive neonates who required cardiac surgery were included in the analysis. Preoperative feeding occurred in 61% (n = 79). The overall prevalence of NEC was 9% (12/130), including three neonates with surgical NEC. There was no difference in the prevalence of NEC between the preoperative feeding and nil per os (NPO) groups. Preoperative NPO status was associated with longer ventilator-dependent days ( P = .01) but was not associated with worsened growth failure, longer length of stay, or increased prevalence of tube-assisted feeds at discharge. In this study cohort, preoperative feeding was associated with a low prevalence of NEC. Larger prospective studies evaluating the safety and benefits of preoperative feeding in cardiac neonates are warranted.

    Blunt cardiac injury is a rare trauma entity. Here, we sought to evaluate the relevance and prognostic significance of blunt cardiac injury in severely injured patients. In a retrospective multicentre study, using data collected from 47,580 patients enrolled to TraumaRegister DGU (1993-2009), characteristics of trauma, prehospital / hospital trauma management, and outcome analysis were correlated to the severity of blunt cardiac injury. The severity of cardiac injury was assessed according to the abbreviated injury score (AIS score 1-6), the revised injury severity score (RISC) allowed comparison of expected outcome with injury severity-dependent outcome. N = 1.090 had blunt cardiac trauma (AIS 1-6) (2.3% of patients). Predictors of blunt cardiac injury could be identified. Sternal fractures indicate a high risk of the presence of blunt cardiac injury (AIS 0 [control]: 3.0%; AIS 1: 19.3%; AIS 2-6: 19.1%). The overall mortality rate was 13.9%, minor cardiac injury (AIS 1) and severe cardiac injury (AIS 2-6) are associated with higher rates. Severe blunt cardiac injury (AIS 4 and AIS 5-6) is associated with a higher mortality (OR 2.79 and 4.89, respectively) as compared to the predicted average mortality (OR 2.49) of the study collective. Multiple injured patients with blunt cardiac trauma are at high risk to be underestimated. Careful evaluation of trauma patients is able to predict the presence of blunt cardiac injury. The severity of blunt cardiac injury needs to be stratified according to the AIS score, as the patients' outcome is dependent on the severity of cardiac injury.

    Cardiac fibrosis remains an important health concern, but the study of fibroblast biology has been hindered by a lack of effective means for identifying and tracking fibroblasts. Recent advances in fibroblast-specific lineage tags and reporters have permitted a better understanding of these cells. After injury multiple cell types have been implicated as the source for extracellular matrix producing cells, but emerging studies suggest that resident cardiac fibroblasts contribute substantially to the remodeling process. In this review, we discuss recent findings regarding cardiac fibroblast origin and identity. Our understanding of cardiac fibroblast biology and fibrosis is still developing and will expand profoundly in the next few years, with many of the recent findings regarding fibroblast gene expression and behavior laying down the groundwork for interpreting the purpose and utility of these cells before and after injury.

    The burden of cardiovascular disease world-wide is one of great concern to patients and health care agencies alike. Traditionally centre-based cardiac rehabilitation (CR) programmes are offered to individuals after cardiac events to aid recovery and prevent further cardiac illness. Home-based cardiac rehabilitation programmes have been introduced in an attempt to widen access and participation. To determine the effectiveness of home-based cardiac rehabilitation programmes compared with supervised centre-based cardiac rehabilitation on mortality and morbidity, health-related quality of life and modifiable cardiac risk factors in patients with coronary heart disease. We updated the search of a previous review by searching the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2007, Issue 4), MEDLINE, EMBASE and CINAHL from 2001 to January 2008. We checked reference lists and sought advice from experts. No language restrictions were applied. Randomised controlled trials (RCTs) that compared centre-based cardiac rehabilitation (e.g. hospital, gymnasium, sports centre) with home-based programmes, in adults with myocardial infarction, angina, heart failure or who had undergone revascularisation. Studies were selected independently by two reviewers, and data extracted by a single reviewer and checked by a second one. Authors were contacted where possible to obtain missing information. Twelve studies (1,938 participants) met the inclusion criteria. The majority of studies recruited a lower risk patient following an acute myocardial infarction (MI) and revascularisation. There was no difference in outcomes of home- versus centre-based cardiac rehabilitation in mortality risk ratio (RR) was1.31 (95% confidence interval (C) 0.65 to 2.66), cardiac events, exercise capacity standardised mean difference (SMD) -0.11 (95% CI -0.35 to 0.13), as well as in modifiable risk factors (systolic blood pressure; diastolic blood pressure; total cholesterol

    The clinical features of cardiac myxoma stroke have not been sufficiently described. Debates remain concerning the options and timing of treatment and the clinical outcomes are unknown. This article aims to highlight the pertinent aspects of this rare condition. Data source of the present study came from a comprehensive literature collection of cardiac myxoma stroke in PubMed, Google search engine and Highwire Press for the year range 2000-2014. Young adults, female predominance, single cerebral vessel (mostly the middle cerebral artery), multiple territory involvements and solitary left atrial myxoma constituted the outstanding characteristics of this patient setting. The most common affected cerebral vessel (the middle cerebral artery) and areas (the basal ganglion, cerebellum and parietal and temporal regions) corresponded well to the common manifestations of this patient setting, such as conscious alteration, ataxia, hemiparesis and hemiplegia, aphasia and dysarthria. Initial computed tomography scan carried a higher false negative rate for the diagnosis of cerebral infarction than magnetic resonance imaging did. A delayed surgical resection of cardiac myxoma was associated with an increased risk of potential consequences in particular otherwise arterial embolism. The mortality rate of this patient population was 15.3%. Cardiac myxoma stroke is rare. Often does it affect young females. For an improved diagnostic accuracy, magnetic resonance imaging of the brain and echocardiography are imperative for young stroke patients in identifying the cerebral infarct and determining the stroke of a cardiac origin. Immediate thrombolytic therapy may completely resolve the cerebral stroke and improve the neurologic function of the patients. An early surgical resection of cardiac myxoma is recommended in patients with not large territory cerebral infarct.

  14. Assessing quality in cardiac surgery

    2005-07-01

    Full Text Available There is a the strong temporal, if not causal, link between the intervention and the outcome in cardiac surgery and therefore a link becomes established between operative mortality and the measurement of surgical performance. In Britain the law stipulates that data collected by any public body or using public funds must be made freely available. Tools and mechanisms we devise and develop are likely to form the models on which the quality of care is assessed in other surgical and perhaps medical specialties. Measuring professional performance should be done by the profession. To measure risk there are a number of scores as crude mortality is not enough. A very important benefit of assessing the risk of death is to use this knowledge in the determination of the indication to operate. The second benefit is in the assessment of the quality of care as risk prediction gives a standard against performance of hospitals and surgeons. Peer review and “naming and shaming” are two mechanisms to monitor quality. There are two potentially damaging outcomes from the publication of results in a league-table form: the first is the damage to the hospital; the second is to refuse to operate on high-risk patients. There is a real need for quality monitoring in medicine in general and in cardiac surgery in particular. Good quality surgical work requires robust knowledge of three crucial variables: activity, risk prediction and performance. In Europe, the three major specialist societies have agreed to establish the European Cardiovascular and Thoracic Surgery Institute of Accreditation (ECTSIA. Performance monitoring is soon to become imperative. If we surgeons are not on board, we shall have no control on its final destination, and the consequences may be equally damaging to us and to our patients.

    The Danish Cardiac Rehabilitation Database (DHRD) aims to improve the quality of cardiac rehabilitation (CR) to the benefit of patients with coronary heart disease (CHD). Hospitalized patients with CHD with stenosis on coronary angiography treated with percutaneous coronary intervention, coronary artery bypass grafting, or medication alone. Reporting is mandatory for all hospitals in Denmark delivering CR. The database was initially implemented in 2013 and was fully running from August 14, 2015, thus comprising data at a patient level from the latter date onward. Patient-level data are registered by clinicians at the time of entry to CR directly into an online system with simultaneous linkage to other central patient registers. Follow-up data are entered after 6 months. The main variables collected are related to key outcome and performance indicators of CR: referral and adherence, lifestyle, patient-related outcome measures, risk factor control, and medication. Program-level online data are collected every third year. Based on administrative data, approximately 14,000 patients with CHD are hospitalized at 35 hospitals annually, with 75% receiving one or more outpatient rehabilitation services by 2015. The database has not yet been running for a full year, which explains the use of approximations. The DHRD is an online, national quality improvement database on CR, aimed at patients with CHD. Mandatory registration of data at both patient level as well as program level is done on the database. DHRD aims to systematically monitor the quality of CR over time, in order to improve the quality of CR throughout Denmark to benefit patients.

    During the past century, cardiac imaging technologies have revolutionized the diagnosis and treatment of acquired and congenital heart disease. Many important contributions to the field of cardiac imaging were initially reported in Radiology. The field developed from the early stages of cardiac imaging, including the use of coronary x-ray angiography and roentgen kymography, to nowadays the widely used echocardiographic, nuclear medicine, cardiac computed tomographic (CT), and magnetic resonance (MR) applications. It is surprising how many of these techniques were not recognized for their potential during their early inception. Some techniques were described in the literature but required many years to enter the clinical arena and presently continue to expand in terms of clinical application. The application of various CT and MR contrast agents for the diagnosis of myocardial ischemia is a case in point, as the utility of contrast agents continues to expand the noninvasive characterization of myocardium. The history of cardiac imaging has included a continuous process of advances in our understanding of the anatomy and physiology of the cardiovascular system, along with advances in imaging technology that continue to the present day.

In the recent years, the excellent surgical results obtained in our institution may be in part due to modern anesthetic care and to postoperative care based on well-structured protocols. The purpose of this article is to review unique aspects of neonate cardiovascular physiology, the impact of extracorporeal circulation on postoperative evolution, and the prescription for pharmacological support of acute cardiac dysfunction based on our cardiac unit protocols. The main causes of low cardiac output after surgical correction of heart congenital disease are reviewed, and methods of treatment and support are proposed as derived from the relevant literature and our protocols.

    OBJECTIVES: The costs of comprehensive cardiac rehabilitation are established and compared to the corresponding costs of usual care. The effect on health-related quality of life is analyzed. METHODS: An unprecedented and very detailed cost assessment was carried out, as no guidelines existed...... for the situation at hand. Due to challenging circumstances, the cost assessment turned out to be ex-post and top-down. RESULTS: Cost per treatment sequence is estimated to be approximately euro 976, whereas the incremental cost (compared with usual care) is approximately euro 682. The cost estimate is uncertain...... and may be as high as euro 1.877. CONCLUSIONS: Comprehensive cardiac rehabilitation is more costly than usual care, and the higher costs are not outweighed by a quality of life gain. Comprehensive cardiac rehabilitation is, therefore, not cost-effective....

    Full Text Available In recent years, developments in the measuring of cardiac output and other haemodynamic variables are focused on the so-called minimally invasive methods. The aim of these methods is to simplify the management of high-risk and haemodynamically unstable patients. Due to the need of invasive approach and the possibility of serious complications the use of pulmonary artery catheter has decreased. This article describes the methods for measuring cardiac output, which are based on volume measurement (Fick method, indicator dilution method, pulse wave analysis, Doppler effect, and electrical bioimpedance.

    The scope and limitations of quantitative cardiac CT have been evaluated in a series of experimental and clinical studies. The left ventricular muscle mass was estimated by computed tomography in 19 dogs (using volumetric methods, measurements in two axes and planes and reference volume). There was good correlation with anatomical findings. The enddiastolic volume of the left ventricle was estimated in 22 patients with cardiomyopathies; using angiography as a reference, CT led to systematic under-estimation. It is also shown that ECG-triggered magnetic resonance tomography results in improved visualisation and may be expected to improve measurements of cardiac morphology.

  4. Mechanisms of Cardiac Regeneration

    2016-01-01

    Adult humans fail to regenerate their hearts following injury, and this failure to regenerate myocardium is a leading cause of heart failure and death worldwide. Although all adult mammals appear to lack significant cardiac regeneration potential, some vertebrates can regenerate myocardium throughout life. In addition, new studies indicate that mammals have cardiac regeneration potential during development and very soon after birth. The mechanisms of heart regeneration among model organisms, including neonatal mice, appear remarkably similar. Orchestrated waves of inflammation, matrix deposition and remodeling, and cardiomyocyte proliferation are commonly seen in heart regeneration models. Understanding why adult mammals develop extensive scarring instead of regeneration is a crucial goal for regenerative biology. PMID:26906733

In conventional cardiac surgery, surgeons can visualize and feel the cardiac structures directly, which is not possible with MICS. Transesophageal echocardiography (TEE is essential during MICS in detecting problems that require immediate correction. Comprehensive evaluation of the cardiac structures and function helps in the confirmation of not only the definitive diagnosis, but also the success of surgical treatment. Venous and aortic cannulations are not under the direct vision of the surgeon and appropriate positioning of the cannulae is not possible during MICS without the aid of TEE. Intra-operative TEE helps in the navigation of the guide wire and correct placement of the cannulae and allows real-time assessment of valvular pathologies, ventricular filling, ventricular function, intracardiac air, weaning from cardiopulmonary bypass and adequacy of the surgical procedure. Early detection of perioperative complications by TEE potentially enhances the post-operative outcome of patients managed with MICS.

    Clinicians rely on age- and size-specific measures of cardiac structures to diagnose cardiac disease. No universally accepted normative data exist for fetal cardiac structures, and most fetal cardiac centers do not use the same standards. The aim of this study was to derive predictive models for Z scores for 13 commonly evaluated fetal cardiac structures using a large heterogeneous population of fetuses without structural cardiac defects. The study used archived normal fetal echocardiograms in representative fetuses aged 12 to 39 weeks. Thirteen cardiac dimensions were remeasured by a blinded echocardiographer from digitally stored clips. Studies with inadequate imaging views were excluded. Regression models were developed to relate each dimension to estimated gestational age (EGA) by dates, biparietal diameter, femur length, and estimated fetal weight by the Hadlock formula. Dimension outcomes were transformed (e.g., using the logarithm or square root) as necessary to meet the normality assumption. Higher order terms, quadratic or cubic, were added as needed to improve model fit. Information criteria and adjusted R 2 values were used to guide final model selection. Each Z-score equation is based on measurements derived from 296 to 414 unique fetuses. EGA yielded the best predictive model for the majority of dimensions; adjusted R 2 values ranged from 0.72 to 0.893. However, each of the other highly correlated (r > 0.94) biometric parameters was an acceptable surrogate for EGA. In most cases, the best fitting model included squared and cubic terms to introduce curvilinearity. For each dimension, models based on EGA provided the best fit for determining normal measurements of fetal cardiac structures. Nevertheless, other biometric parameters, including femur length, biparietal diameter, and estimated fetal weight provided results that were nearly as good. Comprehensive Z-score results are available on the basis of highly predictive models derived from gestational

    2014-11-19

    In medical and surgical intensive care units, clinical risk prediction models for readmission have been developed; however, studies reporting the risks for cardiovascular intensive care unit (CVICU) readmission have been methodologically limited by small numbers of outcomes, unreported measures of calibration or discrimination, or a lack of information spanning the entire perioperative period. The purpose of this study was to derive and validate a clinical prediction model for CVICU readmission in cardiac surgical patients. A total of 10,799 patients more than or equal to 18 years in the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry who underwent cardiac surgery (coronary artery bypass or valvular surgery) between 2004 and 2012 and were discharged alive from the first CVICU admission were included. The full cohort was used to derive the clinical prediction model and the model was internally validated with bootstrapping. Discrimination and calibration were assessed using the AUC c index and the Hosmer-Lemeshow tests, respectively. A total of 479 (4.4%) patients required CVICU readmission. The mean CVICU length of stay (19.9 versus 3.3 days, P prediction model had robust discrimination and calibration in the derivation cohort (AUC c index = 0.799; Hosmer-Lemeshow P = 0.192). The validation point estimates and confidence intervals were similar to derivation model. In a large population-based dataset incorporating a comprehensive set of perioperative variables, we have derived a clinical prediction model with excellent discrimination and calibration. This model identifies opportunities for targeted therapeutic interventions aimed at reducing CVICU readmissions in high-risk patients.

  16. Variations in Cardiac Arrest Regionalization in California

    2018-02-01

    Full Text Available Introduction: The development of cardiac arrest centers and regionalization of systems of care may improve survival of patients with out-of-hospital cardiac arrest (OHCA. This survey of the local EMS agencies (LEMSA in California was intended to determine current practices regarding the treatment and routing of OHCA patients and the extent to which EMS systems have regionalized OHCA care across California. Methods: We surveyed all of the 33 LEMSA in California regarding the treatment and routing of OHCA patients according to the current recommendations for OHCA management. Results: Two counties, representing 29% of the California population, have formally regionalized cardiac arrest care. Twenty of the remaining LEMSA have specific regionalization protocols to direct all OHCA patients with return of spontaneous circulation to designated percutaneous coronary intervention (PCI-capable hospitals, representing another 36% of the population. There is large variation in LEMSA ability to influence inhospital care. Only 14 agencies (36%, representing 44% of the population, have access to hospital outcome data, including survival to hospital discharge and cerebral performance category scores. Conclusion: Regionalized care of OHCA is established in two of 33 California LEMSA, providing access to approximately one-third of California residents. Many other LEMSA direct OHCA patients to PCI-capable hospitals for primary PCI and targeted temperature management, but there is limited regional coordination and system quality improvement. Only one-third of LEMSA have access to hospital data for patient outcomes.

    Liu, Laura X.; Arany, Zolt

    2014-01-01

    Pregnancy causes dramatic physiological changes in the expectant mother. The placenta, mostly foetal in origin, invades maternal uterine tissue early in pregnancy and unleashes a barrage of hormones and other factors. This foetal ‘invasion’ profoundly reprogrammes maternal physiology, affecting nearly every organ, including the heart and its metabolism. We briefly review here maternal systemic metabolic changes during pregnancy and cardiac metabolism in general. We then discuss changes in cardiac haemodynamic during pregnancy and review what is known about maternal cardiac metabolism during pregnancy. Lastly, we discuss cardiac diseases during pregnancy, including peripartum cardiomyopathy, and the potential contribution of aberrant cardiac metabolism to disease aetiology. PMID:24448314

    Leadership skills directly correlate with the quality of technical performance of cardiopulmonary resuscitation (CPR) and clinical outcomes. Despite an improved focus on non-technical skills in CPR training, the leadership of cardiac arrests is often variable. To assess the perceptions of leadership and team working among members of a cardiac arrest team and to evaluate future training needs. Cross-sectional survey of 102 members of a cardiac arrest team at an Acute Hospital Trust in the UK with 892 inpatient beds. Responses sought from doctors, nurses and healthcare assistants to 12 rated statements and 4 dichotomous questions. Of 102 responses, 81 (79%) were from doctors and 21 (21%) from nurses. Among specialist registrars 90% agreed or strongly agreed that there was clear leadership at all arrests compared with between 28% and 49% of nurses and junior doctors respectively. Routine omission of key leadership tasks was reported by as many as 80% of junior doctors and 50% of nurses. Almost half of respondents reported non-adherence with Advanced Life Support (ALS) guidelines. Among junior members of the team, 36% felt confident to lead an arrest and 75% would welcome further dedicated cardiac arrest leadership training. Leadership training is integrated into the ALS (Resus Council, UK) qualification. However, this paper found that in spite of this training; standards of leadership are variable. The findings suggest a pressing need for further dedicated cardiac arrest leadership training with a focus on improving key leadership tasks such as role assignment, team briefing and debriefing.

    2014-02-01

    Cardiac fibrosis is characterized by net accumulation of extracellular matrix proteins in the cardiac interstitium, and contributes to both systolic and diastolic dysfunction in many cardiac pathophysiologic conditions. This review discusses the cellular effectors and molecular pathways implicated in the pathogenesis of cardiac fibrosis. Although activated myofibroblasts are the main effector cells in the fibrotic heart, monocytes/macrophages, lymphocytes, mast cells, vascular cells and cardiomyocytes may also contribute to the fibrotic response by secreting key fibrogenic mediators. Inflammatory cytokines and chemokines, reactive oxygen species, mast cell-derived proteases, endothelin-1, the renin/angiotensin/aldosterone system, matricellular proteins, and growth factors (such as TGF-β and PDGF) are some of the best-studied mediators implicated in cardiac fibrosis. Both experimental and clinical evidence suggests that cardiac fibrotic alterations may be reversible. Understanding the mechanisms responsible for initiation, progression, and resolution of cardiac fibrosis is crucial to design anti-fibrotic treatment strategies for patients with heart disease.

    During the foetal-neonatal period, rhabdomyomas represent the majority of cardiac tumours and are closely associated with tuberous sclerosis. Cardiac rhabdomyomas may be completely asymptomatic and are incidentally discovered during an echocardiogram, or may cause cardiac dysfunctions requiring medical and/or surgical intervention. During foetal life and the early neonatal period, life-threatening conditions, mostly due to arrhythmias, cardiac failure or obstruction, do occur on rare occasions. We reviewed the medical records of all cases of cardiac rhabdomyomas diagnosed prenatally or postnatally over an 8-year period. The present study reviews 7 cases of life-threatening conditions. Arrhythmic episodes were described in 5 patients, and blood flow obstruction was reported in 2 cases. Antiarrhythmic agents successfully controlled the clinical and electrophysiological conditions. Obstructive conditions were associated with poor outcomes. In conclusion, when prenatal diagnosis of rhabdomyoma is made, appropriate planning at delivery for the management of potential haemodynamic complications may prevent adverse neonatal outcomes. The clinical outcome is more influenced by obstructive rather than by dysrhythmic complications. Appropriate antiarrhythmic treatment is of primary importance. In all cases discovered through prenatal and/or neonatal life-threatening conditions, an accurate follow-up should always be performed to anticipate the development of tuberous sclerosis.

  5. Epidemiology and management of cardiac arrest: what registries are revealing.

    Science.gov (United States)

    Gräsner, Jan-Thorsten; Bossaert, Leo

    2013-09-01

    Major European institutions report cardiovascular disease (CVD) as the first cause of death in adults, with cardiac arrest and sudden death due to coronary ischaemia as the primary single cause. Global incidence of CVD is decreasing in most European countries, due to prevention, lifestyle and treatment. Mortality of acute coronary events inside the hospital decreases more rapidly than outside the hospital. To improve the mortality of cardiac arrest outside the hospital, reliable epidemiological and process figures are essential: "we can only manage what we can measure". Europe is a patchwork of 47 countries (total population of 830 million), with a 10-fold difference in incidence of coronary heart disease between North and South, East and West, and a 5-fold difference in number of EMS-treated cardiac arrest (range 17-53/1000,000/year). Epidemiology of cardiac arrest should not be calculated as a European average, but it is appropriate to describe the incidence of cardiac arrest, the resuscitation process, and the outcome in each of the European regions, for benchmarking and quality management. Epidemiological reports of cardiac arrest should specify definitions, nominator (number of cases) and denominator (study population). Recently some regional registries in North America, Japan and Europe fulfilled these conditions. The European Registry of Cardiac Arrest (EuReCa) has the potential to achieve these objectives on a pan-European scale. For operational applications, the Utstein definition of "Cardiac arrest" is used which includes the potential of survival. For application in community health, the WHO definition of "sudden death" is frequently used, describing the mode of death. There is considerable overlap between both definitions. But this explains that no single method can provide all information. Integrating data from multiple sources (local, national, multinational registries and surveys, death certificates, post-mortem reports, community statistics, medical

    The ICTUS trial was a study that compared an early invasive with a selective invasive treatment strategy in patients with non-ST-elevation acute coronary syndrome (nSTE-ACS). The study reported no difference between the strategies for frequency of death, myocardial infarction, or rehospitalisation after 1 year. We did a follow-up study to assess the effects of these treatment strategies after 4 years. 1200 patients with nSTE-ACS and an elevated cardiac troponin were enrolled from 42 hospitals in the Netherlands. Patients were randomly assigned either to an early invasive strategy, including early routine catheterisation and revascularisation where appropriate, or to a more selective invasive strategy, where catheterisation was done if the patient had refractory angina or recurrent ischaemia. The main endpoints for the current follow-up study were death, recurrent myocardial infarction, or rehospitalisation for anginal symptoms within 3 years after randomisation, and cardiovascular mortality and all-cause mortality within 4 years. Analysis was by intention-to-treat. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN82153174. The in-hospital revascularisation rate was 76% in the early invasive group and 40% in the selective invasive group. After 3 years, the cumulative rate for the combined endpoint was 30.0% in the early invasive group compared with 26.0% in the selective invasive group (hazard ratio 1.21; 95% CI 0.97-1.50; p=0.09). Myocardial infarction was more frequent in the early invasive strategy group (106 [18.3%] vs 69 [12.3%]; HR 1.61; 1.19-2.18; p=0.002). Rates of death or spontaneous myocardial infarction were not different (76 [14.3%] patients in the early invasive and 63 [11.2%] patients in the selective invasive strategy [HR 1.19; 0.86-1.67; p=0.30]). No difference in all-cause mortality (7.9%vs 7.7%; p=0.62) or cardiovascular mortality (4.5%vs 5.0%; p=0.97) was seen within 4 years. Long-term follow-up of

    The better understanding of fetal cardiovascular physiology coupled with improved technology for non-invasive study of the fetus now enable much more detailed assessment of fetal cardiac status than by heart rate alone. Even the latter, relatively simple, measurement contains much more information than was previously realized. It is also increasingly clear that no single measurement will provide the answer to all clinical dilemmas either on cardiac function or the welfare of the fetus as a whole. There are obvious clinical advantages in measuring several variables from one signal and the measurement of heart rate, heart rate variation and waveform from the ECG in labour is a potentially useful combination. Systolic time intervals or flow measurements could easily be added or used separately by combining real-time and Doppler ultrasound probes

    1987-01-01

    The book begins with a review of the radionuclide methods available for evaluating cardiac perfusion and function. The authors discuss planar and tomographic thallium myocardial imaging, first-pass and equilibrium radionuclide angiography, and imaging with infarct-avid tracers. Several common but more specialized procedures are then reviewed: nonogemetric measurement of left ventricular volume, phase (Fourier) analysis, stroke volume ratio, right ventricular function, and diastolic function. A separate chapter is devoted to drug interventions and in particular the use of radionuclide ventriculography to monitor doxorubicin toxicity and therapy of congestive heart failure. The subsequent chapters provide a comprehensive guide to test selection, accuracy, and results in acute myocardial infarction, in postmyocardial infarction, in chronic coronary artery disease, before and after medical or surgical revascularization, in valvular heart disease, in cardiomyopathies, and in cardiac trauma.

    Full Text Available Subarachnoid hemorrhage (SAH may present with cardiac arrest (SAH-CA. We report a case of SAH-CA to assist providers in distinguishing SAH as an etiology of cardiac arrest despite electrocardiogram findings that may be suggestive of a cardiac etiology. SAH-CA is associated with high rates of return of spontaneous circulation, but overall poor outcome. An initially non-shockable cardiac rhythm and the absence of brain stem reflexes are important clues in indentifying SAH-CA.

    2004-01-01

    Molecular nuclear cardiac imaging has included Tc-99m Annexin imaging to visualize myocardial apoptosis, but is now usually associated with gene therapy and cell-based therapy. Cardiac gene therapy was not successful so far but cardiac reporter gene imaging was made possible using HSV-TK (herpes simplex virus thymidine kinase) and F-18 FHBG (fluoro-hydroxymethylbutyl guanine) or I-124 FIAU (fluoro-deoxyiodo-arabino-furanosyluracil). Gene delivery was performed by needle injection with or without catheter guidance. TK expression did not last longer than 2 weeks in myocardium. Cell-based therapy of ischemic heart or failing heart looks promising, but biodistribution and differentiation of transplanted cells are not known. Reporter genes can be transfected to the stem/progenitor cells and cells containing these genes can be transplanted to the recipients using catheter-based purging or injection. Repeated imaging should be available and if promoter are varied to let express reporter transgenes, cellular (trans)differentiation can be studied. NIS (sodium iodide symporter) or D2R receptor genes are promising in this aspect

    2015-01-01

    Full Text Available Neurologic outcomes following pediatric cardiac arrest are consistently poor. Early initiation of cardiopulmonary resuscitation has been shown to have positive effects on both survival to hospital discharge, and improved neurological outcomes after cardiac arrest. Additionally, the use of therapeutic hypothermia may improve survival in pediatric cardiac arrest patients admitted to the intensive care unit. We report a child with congenital hypertrophic obstructive cardiomyopathy and an out-of-hospital cardiac arrest, in whom the early initiation of effective prolonged cardiopulmonary resuscitation and subsequent administration of therapeutic hypothermia contributed to a positive outcome with no gross neurologic sequelae. Continuing efforts should be made to promote and employ high-quality cardiopulmonary resuscitation, which likely contributed to the positive outcome of this case. Further research will be necessary to develop and solidify national guidelines for the implementation of therapeutic hypothermia in selected subpopulations of children with OHCA.

    Abstract Rationale: Cardiac metastasis is known as a rare complication of head and neck malignancy. Patient concerns: We present a 58-year-old woman patient with a history of tongue carcinoma who was admitted in emergency department for sudden chest pain. Imaging work-up by computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) diagnosed a cardiac metastasis complicated by intraventricular thrombus and pulmonary embolism. Diagnosis: Cardiac metastasis from tongue carcinoma complicated by pulmonary embolism. Interventions: After undergoing 2 cycles of palliative chemotherapy, the patient declined any further treatment. Outcomes: Patient died 3 months after the diagnosis of cardiac metastasis. Lessons: Cardiac metastasis should be considered as a differential diagnosis in patients with a history of head and neck malignancy who present non-specific cardiac symptoms. PMID:28700484

    Full Text Available Offspring of type 1 diabetic mothers (ODMs are at risk of short-term and long-term complications, such as neonatal macrosomia (birth weight >90th percentile, hypertrophic cardiomyopathy, and cardiovascular morbidity in later life. However, no studies have been performed regarding cardiac outcome. In this study, we investigated cardiac dimensions and function in 30 ODMs at 7-8 years of age in relation to neonatal macrosomia and maternal glycemic control during pregnancy and compared these with those in a control group of 30 children of nondiabetic women. We found that cardiac dimensions and systolic and diastolic function parameters in ODMs were comparable with those in controls. Neonatal macrosomia and poorer maternal glycemic control during pregnancy were not related to worse cardiac outcome in ODM. We conclude that cardiac function at 7-8 years of age in offspring of women with type 1 diabetes is reassuring and comparable with that in controls.

Reporting is mandatory for all hospitals in Denmark delivering CR. The database was initially implemented in 2013 and was fully running from August 14, 2015, thus comprising data at a patient level from the latter date onward.Main variables: Patient-level data are registered by clinicians at the time of entry to CR directly into an online system with simultaneous linkage to other central patient registers. Follow-up data are entered after 6 months. The main variables collected are related to key outcome and performance indicators of CR: referral and adherence, lifestyle, patient-related outcome measures, risk factor control, and medication. Program-level online data are collected every third year.Descriptive data: Based on administrative data, approximately 14,000 patients with CHD are hospitalized at 35 hospitals annually, with 75% receiving one or more outpatient rehabilitation services by 2015. The database has not yet been running for a full year, which explains the use of approximations.Conclusion: The DHRD is an online, national quality improvement database on CR, aimed at patients with CHD. Mandatory registration of data at both patient level as well as program level is done on the database. DHRD aims to systematically monitor the quality of CR over time, in order to improve the quality of CR throughout Denmark to benefit patients.

  20. Genetic and physiologic dissection of the vertebrate cardiac conduction system.

    2008-05-01

    Full Text Available Vertebrate hearts depend on highly specialized cardiomyocytes that form the cardiac conduction system (CCS to coordinate chamber contraction and drive blood efficiently and unidirectionally throughout the organism. Defects in this specialized wiring system can lead to syncope and sudden cardiac death. Thus, a greater understanding of cardiac conduction development may help to prevent these devastating clinical outcomes. Utilizing a cardiac-specific fluorescent calcium indicator zebrafish transgenic line, Tg(cmlc2:gCaMP(s878, that allows for in vivo optical mapping analysis in intact animals, we identified and analyzed four distinct stages of cardiac conduction development that correspond to cellular and anatomical changes of the developing heart. Additionally, we observed that epigenetic factors, such as hemodynamic flow and contraction, regulate the fast conduction network of this specialized electrical system. To identify novel regulators of the CCS, we designed and performed a new, physiology-based, forward genetic screen and identified for the first time, to our knowledge, 17 conduction-specific mutations. Positional cloning of hobgoblin(s634 revealed that tcf2, a homeobox transcription factor gene involved in mature onset diabetes of the young and familial glomerulocystic kidney disease, also regulates conduction between the atrium and the ventricle. The combination of the Tg(cmlc2:gCaMP(s878 line/in vivo optical mapping technique and characterization of cardiac conduction mutants provides a novel multidisciplinary approach to further understand the molecular determinants of the vertebrate CCS.

    Full Text Available Sarcoidosis is a chronic systemic disease of unknown etiology that is characterized by the presence of noncaseating epithelioid granulomas, usually in multiple organs. Several studies have shown that sarcoidosis might be the result of an exaggerated granulomatous reaction after exposure to unidentified antigens in genetically susceptible individuals. Cardiac involvement may occur and lead to an adverse outcome: the heart mechanics will be affected and that causes ventricular failure, and the cardiac electrical system will be disrupted and lead to third degree atrioventricular block, malignant ventricular tachycardia, and sudden cardiac death. Thus, early diagnosis and treatment of this potentially devastating disease is critically important. However, sensitive and accurate imaging modalities have not been established. Recent studies have demonstrated the promising potential of cardiac magnetic resonance imaging (MRI and 18F-fluoro-2-deoxyglucose positron emission tomography (18F-FDG PET in the diagnosis and assessment of cardiac sarcoidosis (CS. In this review, we discuss the epidemiology, etiology, histological findings, and clinical features of sarcoidosis. We also introduce advanced imaging including 18F-FDG PET and cardiac MRI as more reliable diagnostic modalities for CS.

    Suspected myocardial infarction (MI) is a common reason for emergency hospital attendance and admission. Cardiac biomarker measurement is an essential element of diagnostic assessment of suspected MI. Although the cost of a routinely available biomarker may be small, the large patient population and consequences in terms of hospital admission and investigation mean that the economic impact of cardiac biomarker testing is substantial. Economic evaluation involves comparing the estimated costs and effectiveness (outcomes) of two or more interventions or care alternatives. This process creates some difficulties with respect to cardiac biomarkers. Estimating the effectiveness of cardiac biomarkers involves identifying how they help to improve health and how we can measure this improvement. Comparison to an appropriate alternative is also problematic. New biomarkers may be promoted on the basis of reducing hospital admission or length of stay, but hospital admission for low risk patients may incur significant costs while providing very little benefit, making it an inappropriate comparator. Finally, economic evaluation may conclude that a more sensitive biomarker strategy is more effective but, by detecting and treating more cases, is also more expensive. In these circumstances it is unclear whether we should use the more effective or the cheaper option. This article provides an introduction to health economics and addresses the specific issues relevant to cardiac biomarkers. It describes the key concepts relevant to economic evaluation of cardiac biomarkers in suspected MI and highlights key areas of uncertainty and controversy.

    Patients with traumatic cardiac injuries can present with wide variability in their severity of illness. The most severe will present in cardiac arrest, whereas the most benign may be altogether asymptomatic; most will fall somewhere in between. Management of cardiac injuries largely depends on mechanism of injury and patient physiology. Understanding the spectrum of injuries and their associated manifestations can help providers react more quickly and initiate potentially life-saving therapies more efficiently when time is critical. This article discusses the workup and management of both blunt and penetrating cardiac injuries. Copyright © 2017 Elsevier Inc. All rights reserved.

    Huntington's disease is a fatal, hereditary, neurodegenerative disorder best known for its clinical triad of progressive motor impairment, cognitive deficits and psychiatric disturbances. Although a disease of the central nervous system, mortality surveys indicate that heart disease is a leading cause of death. The nature of such cardiac abnormalities remains unknown. Clinical findings indicate a high prevalence of autonomic nervous system dysfunction - dysautonomia - which may be a result of pathology of the central autonomic network. Dysautonomia can have profound effects on cardiac health, and pronounced autonomic dysfunction can be associated with neurogenic arrhythmias and sudden cardiac death. Significant advances in the knowledge of neural mechanisms in cardiac disease have recently been made which further aid our understanding of cardiac mortality in Huntington's disease. Even so, despite the evidence of aberrant autonomic activity the potential cardiac consequences of autonomic dysfunction have been somewhat ignored. In fact, underlying cardiac abnormalities such as arrhythmias have been part of the exclusion criteria in clinical autonomic Huntington's disease research. A comprehensive analysis of cardiac function in Huntington's disease patients is warranted. Further experimental and clinical studies are needed to clarify how the autonomic nervous system is controlled and regulated in higher, central areas of the brain - and how these regions may be altered in neurological pathology, such as Huntington's disease. Ultimately, research will hopefully result in an improvement of management with the aim of preventing early death in Huntington's disease from cardiac causes.

    Full Text Available Cardiac surgery exerts a significant strain on the blood bank services and is a model example in which a multi-modal blood-conservation strategy is recommended. Significant bleeding during cardiac surgery, enough to cause re-exploration and/or blood transfusion, increases morbidity and mortality. Hyper-fibrinolysis is one of the important contributors to increased bleeding. This knowledge has led to the use of anti-fibrinolytic agents especially in pro
