    As the population of elderly people is increasing, the number of patients requiring hospitalization for acute exacerbations is rising. Traditionally, these episodes of hemodynamic instability were viewed as a transient event characterized by systolic dysfunction, low cardiac output, and fluid overload. Diuretics, along with vasodilator and inotropic therapy, eventually became elements of standard care. In a multicenter observational registry (ADHERE--Acute Decompensated Heart Failure National Registry) of more than 275 hospitals, patients with acute decompensated heart failure were analyzed for their characteristics and treatments options. These data have shown that this population consists of multiple types of heart failure, various forms of acute decompensation, combinations of comorbidities, and varying degrees of disease severity. The challenges in the treatment require multidisciplinary approaches since patients typically are elderly and have complex combinations of comorbidities. So far only a limited number of drugs is currently available to treat the different groups. Over the past years it was shown that even "standard drugs" might be deleterious by induction of myocardial injury, worsening of renal function or increasing mortality upon treatment. Therefore, based on pathophysiology, different types of acute decompensated heart failure require specialized treatment strategies.

    Chronic heart failure poses an enormous health care burden to the United States and other developed countries. Acute decompensated heart failure (ADHF) accounts for nearly half of the morbidity and expense of treating this disease. Most patients presenting with ADHF have symptomatic vascular congestion. Diuretics, especially loop diuretics, are the primary pharmacologic intervention used in this population. Despite their widespread use, scant data from randomized clinical trials are available to guide therapeutic choices. In addition, data from several large registries examining weight loss during hospitalization for ADHF suggest that efficacy with diuretic treatment is far from universal. Aggressive diuresis carries a significant risk of electrolyte and volume depletion, with subsequent arrhythmias, hypotension, and worsening renal function. These complications often translate into worse prognosis. Diuretic regimens used to treat ADHF must be individualized based on general knowledge of potency and pharmacokinetic and pharmacodynamic considerations. This article summarizes older and more recent literature to provide a framework for making rational treatment choices in this difficult patient population.

    Over a million patients get hospitalized with the diagnosis of acute decompensated heart failure which poses an insurmountable financial burden on the health care system. Heart failure alone incurs over 30 billion dollars with half the cost spent towards acute hospitalizations. Majority of the treatment strategies have focused towards decongesting patients which often comes with the cost of worsening renal function. Renal dysfunction in the setting of acute decompensated heart failure portends worse morbidity and mortality. Recently, there has been a change in the focus with shift towards therapies attempting to conserve renal function. In the past decade, we have witnessed several large randomized controlled trials testing the established as well as emerging therapies in this subset of population with mixed results. This review intends to provide a comprehensive overview of the pharmacologic therapies commonly utilized in the management of acute decompensated heart failure and the body of evidence supporting these strategies.

    Full Text Available Diuretics, including furosemide, metolazone, and spironolactone, have historically been the mainstay of therapy for acute decompensated heart failure patients. The addition of an aquaretic-like vasopressin antagonist may enhance diuresis further. However, clinical experience with this quadruple combination is lacking in the acute setting. We present two hospitalized patients with acute decompensated heart failure due to massive fluid overload treated with a combination strategy of triple diuretics in conjunction with the aquaretic tolvaptan. The first patient lost 72.1 lbs. (32.7 kg with an average urine output of 3.5 to 7.5 L/day over eight days on combined therapy with furosemide, metolazone, spironolactone, and tolvaptan. The second patient similarly achieved a weight loss of 28.2 lbs. (12.8 kg over 4 days on the same treatment. Both patients maintained stable serum sodium, potassium, and creatinine over this period and remained out of the hospital for more than 30 days. Thus, patients hospitalized with acute decompensated heart failure due to volume overload can achieve euvolemia rapidly and without electrolytes disturbances using this regimen, while being under the close supervision of a team of cardiologists and nephrologists. Additionally, this therapy can potentially decrease the need for ultrafiltration and the length of hospital stay.

    The mortality of heart failure patients with renal insufficiency is high, and these patients tend to develop diuretic resistance. Under these conditions, continuous hemodiafiltration (CHDF) is a possible alternative volume reduction therapy to diuretics. However, its efficacy and safety are not clear. Between April 2005 and March 2008, 248 patients with acute decompensated heart failure were admitted to the CCU of Kyoto City Hospital. Of those patients, 31 (20 volume overloaded heart failure, 11 cardiogenic shock) received CHDF therapy, and their weight loss, acute hemodynamic changes, and clinical outcome were assessed to evaluate the efficacy and safety of CHDF therapy. CHDF was performed for 6.5 +/- 6.5 days. There was no significant change in acute hemodynamics after CHDF initiation. In the volume overloaded heart failure (VH) group, significant weight loss was observed at 24 hours and 48 hours after CHDF initiation (P shock (CS) group were 10.0% and 54.5%, respectively. CHDF for acute decompensated heart failure (ADHF) is a safe, effective, and reliable volume reduction therapy for volume overloaded heart failure. Further investigation is required to assess the effectiveness of CHDF for cardiogenic shock.

    Fluid accumulation is the hallmark of heart failure decompensation. Fluid overload and congestion are associated with recurrent hospitalizations, poor quality of life, and increased mortality in heart failure. Despite the use of high-dose intravenous loop diuretic therapy, acutely decompensated heart failure patients may develop diuretic resistance. Diuretic refractoriness can be a result of elevated intra-abdominal pressure (IAP) in acutely decompensated heart failure. Increased renal venous and interstitial pressures in patients with elevated IAP may lead to renal impairment and diuretic resistance. Routine approaches such as sequential nephron blockade with a combination of loop and thiazide or thiazide-like diuretics, continuous diuretic infusion, and ultrafiltration may not be sufficient. Presented here is a case illustrating the importance of recognizing intra-abdominal hypertension in patients with diuretic resistance. Lowering IAP improves renal perfusion, renal filtration, and diuresis. When elevated, IAP is an easily reversible cause of diuretic resistance. Additionally, abdominal perfusion pressure can be used to guide therapy to reverse end-organ damage and avoid permanent renal replacement therapy.

    Full Text Available BACKGROUND: Heart failure as recognized and treated in typical practice may represent a complex condition that defies discrete categorizations. To illuminate this complexity, we examined treatment strategies for patients hospitalized and treated for decompensated heart failure. We focused on the receipt of medications appropriate for other acute conditions associated with shortness of breath including acute asthma, pneumonia, and exacerbated chronic obstructive pulmonary disease. METHODS AND RESULTS: Using Premier Perspective(®, we studied adults hospitalized with a principal discharge diagnosis of heart failure and evidence of acute heart failure treatment from 2009-2010 at 370 US hospitals. We determined treatment with acute respiratory therapies during the initial 2 days of hospitalization and daily during hospital days 3-5. We also calculated adjusted odds of in-hospital death, admission to the intensive care unit, and late intubation (intubation after hospital day 2. Among 164,494 heart failure hospitalizations, 53% received acute respiratory therapies during the first 2 hospital days: 37% received short-acting inhaled bronchodilators, 33% received antibiotics, and 10% received high-dose corticosteroids. Of these 87,319 hospitalizations, over 60% continued receiving respiratory therapies after hospital day 2. Respiratory treatment was more frequent among the 60,690 hospitalizations with chronic lung disease. Treatment with acute respiratory therapy during the first 2 hospital days was associated with higher adjusted odds of all adverse outcomes. CONCLUSIONS: Acute respiratory therapy is administered to more than half of patients hospitalized with and treated for decompensated heart failure. Heart failure is therefore regularly treated as a broader cardiopulmonary syndrome rather than as a singular cardiac condition.

    This prospective study investigated whether plasma asymmetric dimethylarginine (ADMA) concentrations are related to cardiovascular events in patients with acute heart failure. It has been reported that increased plasma ADMA concentrations are associated with adverse cardiovascular outcome in chronic heart failure. In 118 patients with acute decompensated heart failure and impaired left ventricular function, ADMA and N-terminal pro-brain natriuretic peptide (NT-proBNP) were assessed by high-performance liquid chromatography and by an enzyme-linked immunosorbent assay, respectively. Venous blood was collected at admission and after 1 week, and clinical events were observed during follow-up. All patients (median age 73 years, 96 males) were followed up for a median of 10.7 months. A clinical endpoint (cardiac decompensation, major adverse cardiovascular event, or all-cause mortality) occurred in 66 patients. In 81 patients, changes (Delta) in ADMA or NT-proBNP between admission and a median of 7 days were available. ADMA, NT-proBNP at admission, and DeltaADMA or DeltaNT-proBNP were comparable in patients with and without a clinical endpoint. In contrast to ADMA, NT-proBNP concentrations above the median were associated with higher adjusted hazard ratio for occurrence of an endpoint (HR 2.1; 95% confidence interval 1.2-3.9; P = 0.013). An inverse relationship was observed between DeltaNT-proBNP and endpoints before (P = 0.010) and after (P = 0.015) adjustment for confounders. In patients with acute heart failure, ADMA did not detect patients at future cardiovascular risk.

    Acute decompensated heart failure (ADHF) is a common and highly morbid cardiovascular disorder. Most hospitalizations for ADHF are related to symptoms of congestion, and the vast majority of ADHF patients are treated with intravenous loop diuretics. Despite this nearly ubiquitous use, data supporting the safety and efficacy of loop diuretics in ADHF are limited, and controversy exists about the best way to use loop diuretics with regard to both dosing and means of administration (continuous infusion vs. intermittent boluses). We reviewed the data supporting the safety and efficacy of loop diuretics in patients with ADHF. A large body of observational literature suggests that loop diuretics, especially at higher doses, may be associated with increased mortality in patients with heart failure even after detailed adjustment for other measures of disease severity. Additionally, multiple small underpowered trials suggest that continuous infusion may be equivalent or superior to intermittent bolus dosing. In summary, there is a critical need to develop more robust data on the use of loop diuretics in ADHF. In that context, the NIH Heart Failure Clinical Research Network has begun the Diuretics Optimization Strategies Evaluation (DOSE) study, a multi-center, double-blind, randomized controlled trial that will enroll 300 patients with ADHF. The DOSE study will randomize patients using a 2 × 2 factorial design to low dose vs. high dose furosemide, and intermittent bolus vs. continuous infusion. Successful completion of the DOSE study will provide important data on the optimal clinical use of loop diuretics in ADHF. PMID:19750134

    In patients with acute decompensated heart failure (ADHF), treatment aimed at adequate decongestion of the volume overloaded state is essential. Despite diuretic therapy, many patients remain volume overloaded and symptomatic. In addition, adverse effects related to diuretic treatment are common, including worsening kidney function and electrolyte disturbances. The development of decreased kidney function during treatment affects the response to diuretic therapy and is associated with important clinical outcomes, including mortality. The occurrence of diuretic resistance and the morbidity and mortality associated with diuretic therapy has stimulated interest to develop effective and safe treatment strategies that maximize decongestion and minimize decreased kidney function. During the last few decades, extracorporeal ultrafiltration has been used to remove fluid from diuretic-refractory hypervolemic patients. Recent clinical studies using user-friendly machines have suggested that ultrafiltration may be highly effective for decongesting patients with ADHF. Many questions remain regarding the comparative impact of diuretics and ultrafiltration on important clinical outcomes and adverse effects, including decreased kidney function. This article serves as a summary of key clinical studies addressing these points. The overall goal is to assist practicing clinicians who are contemplating the use of ultrafiltration for a patient with ADHF.

    Full Text Available Background: Matrix metalloproteinases (MMPs are a family of enzymes important for the resorption of extracellular matrices, control of vascular remodeling and repair. Increased activity of MMP2 has been demonstrated in heart failure, and in acutely decompensated heart failure (ADHF a decrease in circulating MMPs has been demonstrated along with successful treatment. Objective: Our aim was to test the influence of spironolactone in MMP2 levels. Methods: Secondary analysis of a prospective, interventional study including 100 patients with ADHF. Fifty patients were non-randomly assigned to spironolactone (100 mg/day plus standard ADHF therapy (spironolactone group or standard ADHF therapy alone (control group. Results: Spironolactone group patients were younger and had lower creatinine and urea levels (all p < 0.05. Baseline MMP2, NT-pro BNP and weight did not differ between spironolactone and control groups. A trend towards a more pronounced decrease in MMP2 from baseline to day 3 was observed in the spironolactone group (-21 [-50 to 19] vs 1.5 [-26 to 38] ng/mL, p = 0.06. NT-pro BNP and weight also had a greater decrease in the spironolactone group. The proportion of patients with a decrease in MMP2 levels from baseline to day 3 was also likely to be greater in the spironolactone group (50% vs 66.7%, but without statistical significance. Correlations between MMP2, NT-pro BNP and weight variation were not statistically significant. Conclusion: MMP2 levels are increased in ADHF. Patients treated with spironolactone may have a greater reduction in MMP2 levels.

    Background Heart failure (HF) is a highly prevalent syndrome. Although the long-term prognostic factors have been identified in chronic HF, this information is scarcer with respect to patients with acute HF. despite available data in the literature on long-term prognostic factors in chronic HF, data on acute HF patients are more scarce. Objectives To develop a predictor of unfavorable prognostic events in patients hospitalized for acute HF syndromes, and to characterize a group at higher risk regarding their clinical characteristics, treatment and outcomes. Methods cohort study of 600 patients admitted for acute HF, defined according to the European Society of Cardiology criteria. Primary endpoint for score derivation was defined as all-cause mortality and / or rehospitalization for HF at 12 months. For score validation, the following endpoints were used: all-cause mortality and / or readmission for HF at 6, 12 and 24 months. The exclusion criteria were: high output HF; patients with acute myocardial infraction, acute myocarditis, infectious endocarditis, pulmonary infection, pulmonary artery hypertension and severe mitral stenosis. Results 505 patients were included, and prognostic predicting factors at 12 months were identified. One or two points were assigned according to the odds ratio (OR) obtained (p < 0.05). After the total score value was determined, a 4-point cut-off was determined for each ROC curve at 12 months. Two groups were formed according to the number of points, group A < 4 points, and group B = 4 points. Group B was composed of older patients, with higher number of comorbidities and predictors of the combined endpoint at 6, 12 and 24 months, as linearly represented in the survival curves (Log rank). Conclusions This risk score enabled the identification of a group with worse prognosis at 12 months.

    Decompensation in heart failure occurs when the heart fails to balance venous return with cardiac output, leading to fluid congestion and contributing to mortality. Decompensated heart failure can cause acute kidney injury (AKI), which further increases mortality. Heart failure activates signaling systems that are deleterious to kidneys such as renal sympathetic nerve activity (RSNA), renin-angiotensin-aldosterone system, and vasopressin secretion. All three reduce renal blood flow (RBF) and increase tubular sodium reabsorption, which may increase renal oxygen consumption causing AKI through renal tissue hypoxia. Vasopressin contributes to venous congestion through aquaporin-mediated water retention. Additional water retention may be mediated through vasopressin-induced medullary urea transport and hyaluronan but needs further study. In addition, there are several systems that could protect the kidneys and reduce fluid retention such as natriuretic peptides, prostaglandins, and nitric oxide. However, the effect of natriuretic peptides and nitric oxide are blunted in decompensation, partly due to oxidative stress. This review considers how neurohormonal signaling in heart failure drives fluid retention by the kidneys and thus exacerbates decompensation. It further identifies areas where there is limited data, such as signaling systems 20-HETE, purines, endothelin, the role of renal water retention mechanisms for congestion, and renal hypoxia in AKI during heart failure.

  18. A retrospective characterization of worsening renal function in patients with acute decompensated heart failure receiving nesiritide

    2009-09-01

    Full Text Available Nesiritide is approved by Food and Drug Administration (FDA for the treatment of patients with acute decompensated heart failure (ADHF due its ability to rapidly reduce cardiac filling pressures and improve dyspnea. Numerous studies have shown that renal dysfunction is associated with unfavorable outcomes in patients with heart failure. In addition, there have been reports suggesting that nesiritide may adversely affect renal function and mortality. Objective: The purpose of this retrospective analysis was to assess the effect of dose and duration of nesiritide use and the dose and duration of diuretic therapy on worsening renal function and increased in-hospital mortality in this patient population.Methods: Seventy-five patients who were hospitalized for ADHF and who were treated with nesiritide for at least 12 hours were reviewed retrospectively. Results: The mean increase in SCr was 0.5 mg/dL (range 0 – 4.4 mg/dL. Thirty-six percent of patients (27/75 met the primary endpoint with an increase in SCr>0.5 mg/dL. Treatment dose and duration of nesiritide did not differ between those patients who had an increase in SCr>0.5 mg/dL and those who did not (p=0.44 and 0.61. Concomitant intravenous diuretics were used in 85% of patients with an increase in SCr >0.5 mg/dL compared to 90% of patients without an increase in SCr>0.5 mg/dL (p=0.57. The in-hospital mortality rate was also higher at 35% in those patients with an increase in creatinine >0.5 mg/dL compared to 11% in those without (p=0.01. Conclusion: Nesiritide was associated with an increase in SCr > 0.5 mg/dL in approximately one-third of patients. The increase occurred independently of dose, duration of nesiritide therapy, blood pressure changes, and concomitant intravenous diuretic use. However, the increase in SCr was associated with an increase in hospital stay and in hospital mortality consistent with previous reports in the literature.

    Since acute kidney injury (AKI) is not always related to mortality in patients with acute decompensated heart failure (ADHF), the aim of this study was to focus on onset time of AKI and its clinical importance. A total of 371 ADHF patients were included. The impact of AKI (≥ 0.3 mg/dl or 1.5-fold increase in serum creatinine level within 48 h) with early onset (≤ 4 days from admission) or late onset (≥ 5 days from admission) was assessed. AKI occurred in 99 patients, who were divided into two groups according to the median onset time of AKI: 50 with early onset of AKI and 49 with late onset of AKI. The maximum increase in serum creatinine level from admission was greater in patients with late onset of AKI than in patients with early onset of AKI (p = 0.012). Patients with late onset of AKI had a higher 12-month mortality rate than that in patients with early onset of AKI (log-rank test, p = 0.014). Late onset of AKI was an independent predictor of mortality (hazard ratio: 3.39, 95 % confidence interval: 1.84-6.18, p time of AKI may be useful for risk stratification of mortality in ADHF patients developing AKI.

    Full Text Available Hospitals today are facing adjustments to reimbursements from excessive readmission rates. One of the most common and expensive causes of readmissions is exacerbation of a heart failure condition. The objective of this paper was to determine if there was an association between the presence of anemia in patients with acute decompensated heart failure and their readmission rate. Using archival data of 4 hospitals in the Miami area, a sample of 847 inpatients with a diagnostic related group (DRG of HF at discharge was considered. There was a significant association between low hemoglobin values and a high rate of readmissions at 14 days and at 30 days in subjects with normal sodium and creatinine values. For subjects with low sodium and high creatinine values, a higher readmission rate was seen in men with low hemoglobin but not in women. These results support a prospective effort to measure the impact of anemia and its treatment on readmission rates.

Laboratory findings showed extremely low level of serum hemoglobin at 1.4 g/dL. Echocardiographic examination demonstrated dilated left ventricular cavity with systolic dysfunction and moderate amount of pericardial effusion. In this patient, acute heart failure due to severe iron deficiency anemia was caused by inappropriate habitual bloodletting. PMID:26755934

    Full Text Available Introduction: Although diuretics are mainly used for the treatment of acute decompensated heart failure (ADHF, inadequate responses and complications have led to the use of extracorporeal ultrafiltration (UF as an alternative strategy for reducing volume overloads in patients with ADHF. Objective: The aim of our study is to perform meta-analysis of the results obtained from studies on extracorporeal venous ultrafiltration and compare them with those of standard diuretic treatment for overload volume reduction in acute decompensated heart failure. Methods: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases were systematically searched using a pre‑specified criterion. Pooled estimates of outcomes after 48 h (weight change, serum creatinine level, and all-cause mortality were computed using random effect models. Pooled weighted mean differences were calculated for weight loss and change in creatinine level, whereas a pooled risk ratio was used for the analysis of binary all-cause mortality outcome. Results: A total of nine studies, involving 613 patients, met the eligibility criteria. The mean weight loss in patients who underwent UF therapy was 1.78 kg [95% Confidence Interval (CI: −2.65 to −0.91 kg; p < 0.001 more than those who received standard diuretic therapy. The post-intervention creatinine level, however, was not significantly different (mean change = −0.25 mg/dL; 95% CI: −0.56 to 0.06 mg/dL; p = 0.112. The risk of all-cause mortality persisted in patients treated with UF compared with patients treated with standard diuretics (Pooled RR = 1.00; 95% CI: 0.64–1.56; p = 0.993. Conclusion: Compared with standard diuretic therapy, UF treatment for overload volume reduction in individuals suffering from ADHF, resulted in significant reduction of body weight within 48 h. However, no significant decrease of serum creatinine level or reduction of all-cause mortality was observed.

    The short- and long-term morbidity and mortality in acute heart failure is still unacceptably high. There is an unmet need for new therapy options with new drugs with a new mode of action. One of the drugs currently in clinical testing in Phase III is ularitide, which is the chemically synthesized form of the human natriuretic peptide urodilatin. Urodilatin is produced in humans by differential processing of pro-atrial natriuretic peptide in distal renal tubule cells. Physiologically, urodila...

    Although hypoalbuminemia at admission is a risk for acute kidney injury (AKI) and mortality in patients with acute decompensated heart failure (ADHF), the clinical significance of decreased serum albumin levels (DAL) during ADHF therapy has not been elucidated. This study aimed to evaluate whether DAL was associated with AKI, and whether intravenous atrial natriuretic peptide (ANP) administration, which provides an effective treatment for ADHF but promotes albumin extravasation, was associated with DAL and AKI. A total of 231 consecutive patients with ADHF were enrolled. AKI was defined as ≥0.3 mg/dl absolute or 1.5-fold increase in serum creatinine levels within 48 h. AKI occurred in 73 (32%) of the 231 patients during ADHF therapy. The median value of decreases in serum albumin levels was 0.3 g/dl at 7 days after admission. When DAL was defined as ≥0.3 g/dl decrease in serum albumin levels, DAL occurred in 113 patients, and was independently associated with AKI. Of the 231 patients, 73 (32%) were treated with intravenous ANP. DAL occurred more frequently in patients receiving ANP than in those not receiving ANP (77 vs. 36%, p < 0.001), and ANP was independently associated with DAL. The incidence of AKI was higher in patients receiving ANP than in those not receiving ANP (48 vs. 24%, p < 0.001). ANP was independently associated with AKI. In conclusion, DAL is associated with AKI. Intravenous ANP administration may be one of the promoting factors of DAL, which leads to AKI, indicating a possible novel mechanism of AKI.

    Full Text Available Ferenc FollathUniversity Hospital Zürich, Steering Group Drug Therapy, Zürich, SwitzerlandAbstract: Acute heart failure (AHF is a major cause of hospitalizations. Severe dyspnea, pulmonary congestion and low cardiac output with peripheral vasoconstriction and renal hypoperfusion is a main form of clinical presentation. Most patients with acute worsening have a pre-existing decompensated chronic heart failure (ADCHF, but AHF may also occur as a first manifestation of a previously unknown heart disease. Myocardial ischemia, cardiac arrhythmias, non-compliance with medication and infections are frequent precipitating factors. Management of AHF depends on the underlying heart disease and cause of decompensation. In patients with ADCHF vasodilators and iv diuretics are first-line drugs for rapid reduction of dyspnea and congestion. In patients with signs of low cardiac output and oliguria, inotropic agents are also often administered to prevent further deterioration. Beta-adrenergic agents and phosphodiesterase inhibitors correct the hemodynamic disturbance, but may also induce arrhythmias and worsen myocardial ischemia. Inotropic therapy therefore remains controversial. A novel class of drugs, the calcium sensitizers, represent a new therapeutic option. Levosimendan was shown to improve myocardial contractility without increasing oxygen requirements and to produce peripheral and coronary vasodilation. Its therapeutic effects and tolerance have been tested in several trials. The present review focuses on the clinical pharmacology and therapeutic utility of levosimendan in patients with ADCHF.Keywords: acute heart failure, inotropic agents, calcium sensitizers, levosimendan

    Renal injury is an important factor for worsening outcome in acute decompensated heart failure (ADHF). An 81-year-old woman was admitted due to ADHF with dyspnea and mild peripheral edema. The patient was managed with intravenous administration of atrial natriuretic peptide (ANP) at a dose of 0.0125 μg/kg/minute, which did not control volume overload even at an increased dose of 0.025 μg/kg/minute. After a low dose of dopamine (DA) of 1.0 μg/kg/ minute was added, urine output increased markedly to 120 from 30 mL/hour. Furthermore, her heart rate decreased to 80-100 from 120 bpm and the congestion improved with a reduced brain natriuretic peptide level. Interestingly, the combination of ANP and DA therapy reduced serum creatinine as well as the levels of urinary liver-type fatty acid binding protein, a novel reno-tubular stress marker, by 98.9%, and an oxidative stress marker, urinary 8-hydroxydeoxyguanosine, by 88.2% from baseline levels. Thus, this ADHF patient, a nonresponder to ANP alone, improved without renal injury when administered combination therapy consisting of low doses of ANP and DA, suggesting that this combined therapy might be useful for better management of ADHF in patients without diuretic responses with ANP alone. Further prospective studies are warranted.

    Full Text Available Background: Several studies have shown that hyponatremia is associated with increased risk of rehospitalization and death in patients with heart failure. In these studies, chronic heart failure (CHF patients with persistent hyponatremia were compared only with CHF patients with a normal sodium level at hospital admission. Aims: In the present retrospective study, conducted in a cohort of patients with recent acute decompensated heart failure (ADHF, all with hyponatremia ascertained at the time of hospital admission, we aimed to evaluate the effect of the normalization of serum sodium on the composite endpoint of short-term rehospitalization and mortality. Methods: A retrospective study centered on medical records of patients hospitalized for ADHF in the period April 2013 to April 2016 was performed. Data regarding serum sodium measurements had to be collected from medical records of cardiology wards of two hospitals, and were then processed for statistical analysis. As an inclusion criterion for enrollment, patients had to be suffering from heart failure that had required at least one hospitalization. Moreover, they had to be suffering from a state of hyponatremia (serum sodium < 135 mEq/L at admission on the occasion of the index hospitalization. Patients with hyponatremia at admission were divided into two groups, one comprising patients with hyponatremia that persisted at the time of discharge (persistent hyponatremia and a second including patients who had achieved normalization of their serum sodium levels (serum Na+ ≥ 135 mEq/L during hospitalization until discharge. For both groups, the risk of mortality and rehospitalization during a 30-day follow-up was assessed. Results: One hundred and sixty CHF patients with various degrees of functional impairment were enrolled in the study. Among them, 56 (35% had persistent hyponatremia over the course of hospitalization. At multivariable Cox proportional-hazards regression analysis, the risk of

    Full Text Available Patients with acute decompensated heart failure (ADHF frequently develop worsening in renal function until Acute Kidney Injury (AKI. The use of kidney injury biomarkers could be useful in the early diagnosis of AKI. In the present study, the role of the neutrophil gelatinase-associated lipocalin (NGAL, compared to the standard creatinine, in ADHF patients, was analyzed to evaluate if an early treatment could affect the outcome. A case series of 24 ADHF patients was enrolled and patients randomly divided in two groups (Group A and Group B. In Group A, NGAL, creatinine, and eGFR were measured, while in Group B, creatinine and eGFR alone were measured. NGAL was measured by turbidimetric immunoassay and creatinine using an enzymatic spectrophotometric method. In presence of AKI, creatinine increase and eGFR decrease were significantly lower in Group A than in Group B, whereas in absence of AKI the difference between the two groups was not significant. Hospitalization stay was significantly lower in Group A (receiving early treatment based on NGAL than in Group B. In ADHF patients, plasma NGAL in combination with creatinine was superior to the standard creatinine in the diagnosis and early treatment of AKI with a better outcome and a decreased hospital stay.

    Aims To determine if newer criteria for diagnosing and staging acute kidney injury (AKI) during heart failure (HF) admission are more predictive of clinical outcomes at 30 days and 1 year than the traditional worsening renal function (WRF) definition. Methods We analyzed prospectively collected clinical data on 637 HF admissions with 30-day and 1-year follow-up. The incidence, stages, and outcomes of AKI were determined using the following four definitions: KDIGO, RIFLE, AKIN, and WRF (serum creatinine rise ≥0.3 mg/dl). Receiver operating curves were used to compare the predictive ability of each AKI definition for the occurrence of adverse outcomes (death, rehospitalization, dialysis). Results AKI by any definition occurred in 38.3% (244/637) of cases and was associated with an increased incidence of 30-day (32.3 vs. 6.9%, χ2 = 70.1; p < 0.001) and 1-year adverse outcomes (67.5 vs. 31.0%, χ2 = 81.4; p < 0.001). Most importantly, there was a stepwise increase in primary outcome with increasing stages of AKI severity using RIFLE, KDIGO, or AKIN (p < 0.001). In direct comparison, there were only small differences in predictive abilities between RIFLE and KDIGO and WRF concerning clinical outcomes at 30 days (AUC 0.76 and 0.74 vs. 0.72, χ2 = 5.6; p = 0.02) as well as for KDIGO and WRF at 1 year (AUC 0.67 vs. 0.65, χ2 = 4.8; p = 0.03). Conclusion During admission for HF, the benefits of using newer AKI classification systems (RIFLE, AKIN, KDIGO) lie with the ability to identify those patients with more severe degrees of AKI who will go on to experience adverse events at 30 days and 1 year. The differences in terms of predictive abilities were only marginal. PMID:23801998

    Full Text Available OBJECTIVE: To identify predictors of low cardiac output and mortality in decompensated heart failure. INTRODUCTION: Introduction: Patients with decompensated heart failure have a high mortality rate, especially those patients with low cardiac output. However, this clinical presentation is uncommon, and its management is controversial. METHODS: We studied a cohort of 452 patients hospitalized with decompensated heart failure with an ejection fraction of 60 years, and 64.6% were men. Low cardiac output was present in 281 (63% patients on admission. Chagas disease was the cause of heart failure in 92 (20.4% patients who had higher B type natriuretic peptide levels (1,978.38 vs. 1,697.64 pg/mL; P = 0.015. Predictors of low cardiac output were Chagas disease (RR: 3.655, P<0.001, lower ejection fraction (RR: 2.414, P<0.001, hyponatremia (RR: 1.618, P = 0.036, and renal dysfunction (RR: 1.916, P = 0.007. Elderly patients were inversely associated with low cardiac output (RR: 0.436, P = 0.001. Predictors of mortality were Chagas disease (RR: 2.286, P<0.001, ischemic etiology (RR: 1.449, P = 0.035, and low cardiac output (RR: 1.419, P = 0.047. CONCLUSIONS: In severe decompensated heart failure, predictors of low cardiac output are Chagas disease, lower ejection fraction, hyponatremia, and renal dysfunction. Additionally, Chagas disease patients have higher B type natriuretic peptide levels and a worse prognosis independent of lower ejection fraction.

    Heart failure (HF) is a common disease associated with increasing age. B-type natriuretic peptide (BNP), is a cardiac neurohormone, and is released as prepro BNP and then enzyrnatically cleaved to the Ntenninal-proBNP (NT-proBNP) and BNP upon ventricular myocyte stretch. Blood measurements of BNP have been used to identify patients with I-IF. The BNP assay is currently used as a diagnostic and prognostic aid in HF. In general, a BNP level below 100 pg/mL excludes acutely decompensated HF and levels > 500 pg/ml indicate decompensation. Recombinant human BNP (hBNP, nesiritide) is an approved intravenous treatment for acute,decompensated -HF. Nesiritide given in supraphysiologic doses causes vasodilation, natriuresis, diuresis, and improved symptoms over the course of a 48-hour infusion. This paper will sort out the literature concerning the use of this peptide both as a diagnostic test and as an intravenous therapy.

    Nicorandil, an adenosine triphosphate-sensitive potassium channel opener, improves cardiac sympathetic nerve activity (CSNA) in ischemic heart disease or chronic heart failure. However, its effects on CSNA and myocyte dysfunction in acute heart failure (AHF) remain unclear. We investigated the effects of adding intravenous nicorandil to standard therapy on CSNA and myocyte dysfunction in AHF. We selected 70 patients with mild to moderate nonischemic AHF who were treated with standard conventional therapy soon after admission. Thirty-five patients were assigned to additionally receive intravenous nicorandil (4-12 mg/h; group A), whereas the remaining patients continued their current drug regimen (group B). Delayed total defect score (TDS), delayed heart to mediastinum count (H/M) ratio, and washout rate (WR) were determined by {sup 123}I-metaiodobenzylguanidine (MIBG) scintigraphy within 3 days of admission and 4 weeks later. High sensitivity troponin T (hs-TnT) level was also measured at the same time points. After treatment, MIBG scintigraphic parameters significantly improved in both groups. However, the extent of the changes in these parameters in group A significantly exceeded the extent of the changes in group B [TDS -11.3 ± 4.3 in group A vs -4.0 ± 6.0 in group B (p < 0.01); H/M ratio 0.31 ± 0.16 vs 0.14 ± 0.16 (p < 0.01); WR -13.8 ± 7.8 % vs -6.1 ± 8.9 % (p < 0.01)]. The hs-TnT level decreased significantly from 0.052 ± 0.043 to 0.041 ± 0.033 ng/ml (p < 0.05) in group A, but showed no significant change in group B. Moreover, in both groups, no relationships between the extent of changes in MIBG parameters and hs-TnT level were observed. Adding intravenous nicorandil to standard therapy provides additional benefits for CSNA and myocyte dysfunction over conventional therapy alone in AHF patients. Furthermore, the mechanisms of improvement in CSNA and myocyte dysfunction after nicorandil treatment in AHF patients were distinct. (orig.)

    Background B-type natriuretic peptide (BNP) is regarded as a reliable predictor of outcome in patients with acute decompensated heart failure (ADHF). However, according to some scholars, a single isolated measurement of serum BNP at the time of hospital admission would not be sufficient to provide reliable prognostic information. Methods A retrospective study was carried out on patients hospitalized for ADHF, who had then undergone follow-up of at least 6 months, in order to see if there was any difference in midterm mortality among patients with rising BNP at discharge as compared to those with decreasing BNP at discharge. Medical records had to be carefully examined to divide the case records into two groups, the former characterized by an increase in BNP during hospitalization, and the latter showing a decrease in BNP from the time of admission to the time of discharge. Results Ultimately, 177 patients were enrolled in a retrospective study. Among them, 53 patients (29.94%) had increased BNPs at the time of discharge relative to admission, whereas 124 (70.06%) exhibited decreases in serum BNP during their hospital stay. The group with patients who exhibited BNP increases at the time of discharge had higher degree of congestion evident in the higher frequency of persistent jugular venous distention (odds ratio: 3.72; P = 0.0001) and persistent orthopnea at discharge (odds ratio: 2.93; P = 0.0016). Moreover, patients with increased BNP at the time of discharge had a lower reduction in inferior vena cava maximum diameter (1.58 ± 2.2 mm vs. 6.32 ± 1.82 mm; P = 0.001 (one-way ANOVA)). In contrast, there was no significant difference in weight loss when patients with increased BNP at discharge were compared to those with no such increase. A total of 14 patients (7.9%) died during the 6-month follow-up period. Cox proportional hazard analysis revealed that BNP increase at the time of discharge was an independent predictor of 6-month all-cause mortality after

    AIM: To evaluate plasma levels of nitrite/nitrate (NOx),soluble Fas (sFas) antigen, tumor necrosis factor alpha(TNF-α) and interleukin-6 (TL-6) in patients with compensated and acute decompensated cirrhosis and to evaluate mediators causing acute decompensation in liver cirrhosis.METHODS: This prospective study was conducted in the medical intensive care unit of an academic tertiary center. Fifty-five patients with acute decompensation (gastrointestinal hemorrhage, encephalopathy, hydropic decompensation) and twenty-five patients with compensated liver cirrhosis were included. Blood samples were taken for analyses of sfas, Nox, TL-6, TNF-α. Liver enzymes and kidney functions were also tested.RESULTS: In patients with acute decompensation, plasma sfas levels were higher than in non-decompensated patients (15305±4646 vs 12458 ± 4322 pg/mL, P <0.05). This was also true for the subgroup of patients with alcoholic liver cirrhosis (P < 0.05). The other mediators were not different and none of the parameters predicted survival, except for ALT (alanine-aminotransferase). In patients with portal-hypertension-induced acute hemorrhage, NOx levels were significantly lower than in patients with other forms of decompensation (70.8 ±48.3 vs 112.9 ± 74.9 pg/mL, P < 0.05). When NOx levels were normalized to creatinine levels, the difference disappeared. IL-6, TNF-α and sfas were not different between bleeders and non-bleeders. In decompensated patients sfas, IL-6 and NOx levels correlated positively with creatinine levels, while IL-6 levels were dependent on Child class.CONCLUSION: In acute decompensated cirrhotic patients sFas is increased, suggesting a role of apoptosis in this process and patients with acute bleeding have lower NOx levels. However, in this acute complex clinical situation, kidney function seems to have a predominant influence on mediator levels.

    Background Exacerbations of heart failure appear frequently associated with precipitating factors not directly related to the evolution of cardiac disease. There still a paucity of data on the proportional distribution of precipitating factors specifically in elderly patients. The aim of this study was to examine prospectively the precipitating factors leading to hospitalization in elderly patients with heart failure in our community hospital. Methods We evaluate elderly patients who need admissions for decompensate heart failure. All patients were reviewed daily by the study investigators at the first 24 h and closely followed-up. Decompensafion was defined as the worsening in clinical NYHA class associated with the need for an increase in medical treatment (at minimum intravenously diuretics). Results We included 102 patients (mean age 79 ± 12 years). Precipitating factors were identified in 88.5%. The decompensation was sudden in 35% of the cases.Noncompliance with diet was identified in 52% of the patients, lack of adherence to the prescribed medications amounted to 30%. Others precipitating factors were infections (29%), arrhythmias (25%), acute coronary ischemia (22%), and uncontrolled hypertension (15%),miscellaneous causes were detected in 18% of the cases (progression of renal disease 60%, anemia 30% and iatrogenic factors 10%).Concomitant cause was not recognizable in 11.5%. Conclusions Large proportion heart failure hospitalizations are associated with preventable precipitating factors. Knowledge of potential precipitating factors may help to optimize treatment and provide guidance for patients with heart failure. The presence of potential precipitating factors should be routinely evaluated in patients presenting chronic heart failure.

    Full Text Available The urea cycle functions to incorporate ammonia, generated by normal metabolism, into urea. Urea cycle disorders (UCDs are caused by loss of function in any of the enzymes responsible for ureagenesis, and are characterized by life-threatening episodes of acute metabolic decompensation with hyperammonemia (HA. A prospective analysis of interim HA events in a cohort of individuals with ornithine transcarbamylase (OTC deficiency, the most common UCD, revealed that intercurrent infection was the most common precipitant of acute HA and was associated with markers of increased morbidity when compared with other precipitants. To further understand these clinical observations, we developed a model system of metabolic decompensation with HA triggered by viral infection (PR8 influenza using spf-ash mice, a model of OTC deficiency. Both wild-type (WT and spf-ash mice displayed similar cytokine profiles and lung viral titers in response to PR8 influenza infection. During infection, spf-ash mice displayed an increase in liver transaminases, suggesting a hepatic sensitivity to the inflammatory response and an altered hepatic immune response. Despite having no visible pathological changes by histology, WT and spf-ash mice had reduced CPS1 and OTC enzyme activities, and, unlike WT, spf-ash mice failed to increase ureagenesis. Depression of urea cycle function was seen in liver amino acid analysis, with reductions seen in aspartate, ornithine and arginine during infection. In conclusion, we developed a model system of acute metabolic decompensation due to infection in a mouse model of a UCD. In addition, we have identified metabolic perturbations during infection in the spf-ash mice, including a reduction of urea cycle intermediates. This model of acute metabolic decompensation with HA due to infection in UCD serves as a platform for exploring biochemical perturbations and the efficacy of treatments, and could be adapted to explore acute decompensation in other

OBJECTIVE: To describe the prevalence of PE and to assess the diagnostic accuracy of the Wells and Geneva scores in patients hospitalized due to HF. METHODS: Patients hospitalized primarily due to HF underwent systematic ventilation-perfusion lung scan, and PE was defined by a result of high probability. Aiming at interpreting, low clinical probability of PE was defined as prevalence < 5%, according to the literature. When calculating the sample size, 49 patients were required to provide a 95% confidence interval with ±10% accuracy, estimating an a priori prevalence of 15%. RESULTS: Of 51 patients studied, six had a high probability of PE on lung scan, resulting in 12% prevalence (95% CI = 5% - 23%. The Wells and Geneva scores had an area under the ROC curve of 0.53 (95% CI = 0.27 - 0.80; p = 0.80 and 0.43 (95% CI = 0.13 - 0.73; p = 0.56, respectively, indicating lack of accuracy for the diagnosis of PE.

    While pharmaceutical innovation has been highly successful in reducing mortality in chronic heart failure, this has not been matched by similar success in decompensated heart failure syndromes. Despite outstanding issues over definitions and end points, we argue in this paper that an unprecedented wealth of pharmacologic innovation may soon transform the management of these challenging patients. Agents that target contractility, such as cardiac myosin activators and novel adenosine triphosphate-dependent transmembrane sodium-potassium pump inhibitors, provide inotropic support without arrhythmogenic increases in cytosolic calcium or side effects of more traditional agents. Adenosine receptor blockade may improve glomerular filtration and diuresis by exerting a direct beneficial effect on glomerular blood flow while vasopressin antagonists promote free water excretion without compromising renal function and may simultaneously inhibit myocardial remodeling. Urodilatin, the renally synthesized isoform of atrial natriuretic peptide, may improve pulmonary congestion via vasodilation and enhanced diuresis. Finally, metabolic modulators such as perhexiline may optimize myocardial energy utilization by shifting adenosine triphosphate production from free fatty acids to glucose, a unique and conceptually appealing approach to the management of heart failure. These advances allow optimism not only for the advancement of our understanding and management of decompensated heart failure syndromes but for the translational research effort in heart failure biology in general.

    Maple syrup urine disease (MSUD) is an inborn error of amino acid metabolism, which affects the brain tissue resulting in impairment or death if untreated. Imaging studies have shown reversible brain edema during acute metabolic decompensation. The purpose of this paper is to describe the diffusion-weighted imaging (DWI) and spectroscopy findings during metabolic decompensation and to assess the value of these findings in the prediction of patient outcome. Six patients with the diagnosis of MSUD underwent conventional MR imaging with DWI during acute presentation with metabolic decompensation. Spectroscopy with long TE was performed in four of the six patients. Follow-up examinations were performed after clinical and metabolic recovery. DWI demonstrated marked restriction of proton diffusion compatible with cytotoxic or intramyelinic sheath edema in the brainstem, basal ganglia, thalami, cerebellar and periventricular white matter and the cerebral cortex. This was accompanied by the presence of an abnormal branched-chain amino acids (BCAA) and branched-chain alpha-keto acids (BCKA) peak at 0.9 ppm as well as elevated lactate on proton spectroscopy in all four patients. The changes in all six patients were reversed with treatment without evidence of volume loss or persistent tissue damage. The presence of cytotoxic or intramyelinic edema as evidenced by restricted water diffusion on DWI, with the presence of lactate on spectroscopy, could imply imminent cell death. However, in the context of metabolic decompensation in MSUD, it appears that changes in cell osmolarity and metabolism can reverse completely after metabolic correction. (orig.)

    Full Text Available Acute metabolic decompensation in maple syrup urine disease can occur during intercurrent illness and is a medical emergency. A handful of reports in the medical literature describe the use of peritoneal dialysis and haemodialysis as therapeutic inventions. We report the only patient from our centre to have haemodialysis performed in this setting. Combined with dietary BCAA restriction and calorific support, haemodialysis allows rapid reduction in plasma leucine concentrations considerably faster than conservative methods.

    Hepatic encephalopathy in a hospitalized cirrhotic patient is associated with a high mortality rate and its presence adds further to the mortality of patients with acute-on-chronic liver failure (ACLF). The exact pathophysiological mechanisms of HE in this group of patients are unclear but hyperammonemia, systemic inflammation (including sepsis, bacterial translocation, and insulin resistance) and oxidative stress, modulated by glutaminase gene alteration, remain as key factors. Moreover, alcohol misuse, hyponatremia, renal insufficiency, and microbiota are actively explored. HE diagnosis requires exclusion of other causes of neurological, metabolic and psychiatric dysfunction. Hospitalization in the ICU should be considered in every patient with overt HE, but particularly if this is associated with ACLF. Precipitating factors should be identified and treated as required. Evidence-based specific management options are limited to bowel cleansing and non-absorbable antibiotics. Ammonia lowering drugs, such as glycerol phenylbutyrate and ornithine phenylacetate show promise but are still in clinical trials. Albumin dialysis may be useful in refractory cases. Antibiotics, prebiotics, and treatment of diabetes reduce systemic inflammation. Where possible and not contraindicated, large portal-systemic shunts may be embolized but liver transplantation is the most definitive step in the management of HE in this setting. HE in patients with ACLF appears to be clinically and pathophysiologically distinct from that of acute decompensation and requires further studies and characterization.

    Alterations in energetic state of the myocardium are associated with decompensated heart failure in humans and in animal models. However, the functional consequences of the observed changes in energetic state on mechanical function are not known. The primary aim of the study was to quantify mechanical/energetic coupling in the heart and to determine if energetic dysfunction can contribute to mechanical failure. A secondary aim was to apply a quantitative systems pharmacology analysis to investigate the effects of drugs that target cross-bridge cycling kinetics in heart failure-associated energetic dysfunction. Herein, a model of metabolite- and calcium-dependent myocardial mechanics was developed from calcium concentration and tension time courses in rat cardiac muscle obtained at different lengths and stimulation frequencies. The muscle dynamics model accounting for the effect of metabolites was integrated into a model of the cardiac ventricles to simulate pressure-volume dynamics in the heart. This cardiac model was integrated into a simple model of the circulation to investigate the effects of metabolic state on whole-body function. Simulations predict that reductions in metabolite pools observed in canine models of heart failure can cause systolic dysfunction, blood volume expansion, venous congestion, and ventricular dilation. Simulations also predict that myosin-activating drugs may partially counteract the effects of energetic state on cross-bridge mechanics in heart failure while increasing myocardial oxygen consumption. Our model analysis demonstrates how metabolic changes observed in heart failure are alone sufficient to cause systolic dysfunction and whole-body heart failure symptoms.

    Full Text Available Background: Conventional diagnostic procedures and therapy of acute liver failure (ALF and acute-on-chronic liver failure (ACLF focus on to identify triggering events of the acute deterioration of the liver function and to avoid them. Further objectives are to prevent the development respectively the progression of secondary organ dysfunctions or organ failure. Most of the times the endocrinological function of the liver can to a wide extent be compensated, but the removal of toxins can only marginally be substituted by conventional conservative therapy. To improve this component of the liver function is the main objective of extracorporal liver support systems. The following principles of liver support systems can be differentiated: Artificial systems, bioartifical systems and extracorporal liver perfusion systems. This HTA report focuses on artificial systems (e.g. BioLogic-DT/-DTPF, MARS, Prometheus, because only these approaches currently are relevant in the German health care system. In 2004 a category "Extracorporal liver assist device" was introduced in the list of "additional payments" in the German DRG-system, which makes reimbursement for hospitals using the technology in inpatient care possible, based on an hospital's individual contract with statutory sickness funds. Objectives: To report the present evidence and future research need on medical efficacy and economic effectiveness of extracorporal liver support devices for treatment of patients with ALF or ACLF based on published literature data. Are artificial liver support systems efficient and effective in the treatment of ALF or ACLF? Methods: An extensive, systematic literature search in medical, economic, and HTA literature data bases was performed. Relevant data were extracted and synthesised. Results: Relevant controlled trials were detected for BioLogic-DT and MARS. No randomised controlled trial on Prometheus was found. None of the included studies on BioLogic-DT showed

Methods One hundred and two consecutive patients with acute decompensated heart failure and left ventricular ejection fraction (LVEF) below 50% on echocardiogram were enrolled. The value of TASPE, LVEF and pulmonary arterial systolic pressure (PASP) were measured by the transthoracic echocardiography. Blood test was conducted to determine NT-proBNP, electrolytes, BUN and creatinine. The estimated GFR (eGFR) was calculated on the basis of simplified Modification of Diet in Renal Disease (MDRD). According to the eGFR, the patients were divided into preserved re-nal function (PRF) group [eGFR≥60 ml/(min·1.73m2), =54] and renal dysfunction (RDSF) group [eGFR﹤60 ml/(min·1.73m2), = 48]. The echocardiographic parameters and serum indexes were compared between the two groups. The correlations between TASPE and echocardiographic parameters, serum indexes in the RDSF group were analyzed. Results TASPE in the PRF group [(16.4 ± 4.0) mm] was significantly lower than that in the RDSF group [(18.9 ± 3.8) mm, ﹤ 0.001], but no significant difference in NT-proBNP, PASP or LVEF was observed between the two groups ( ﹥ 0

    The tricarboxylic acid (TCA) cycle represents the key enzymatic steps in cellular energy metabolism. Once the TCA cycle is impaired in case of inherited metabolic disorders, life-threatening episodes of metabolic decompensation and severe organ failure can arise. We present the case of a 6 ½-year-old girl with propionic acidaemia during an episode of acute life-threatening metabolic decompensation and severe lactic acidosis. Citric acid given as an oral formulation showed the potential to sustain the TCA cycle flux. This therapeutic approach may become a treatment option in a situation of acute metabolic crisis, possibly preventing severe disturbance of energy metabolism.

    Full Text Available Introduction: Hearth failure frequently seems with depression and increases the morbidity and mortality with worse prognosis. In this study, we aimed to investigate the psychological situation of decompensated syctolic heart failure (DSHF patients and applied medical and psychological therapy to them.Materials and Methods: Totally 71 patients enrolled to the study which entered to Cardiology Department of Abant Izzet Baysal University Medical School Hospital with diagnosis of functional class II-IV DSHF according to New York Cardiology Association classification and ejection fraction (EF of 40% or lower. These patients were divided into two groups (Group A: NHYA grade 2-3, Group B NYHA grade 4. The depression of patients were evaluated by geriatric depression scale (GDS.Results: Twenty one (29.6% of 71 patients had depression consisting of 8 (38% male and 13 (62% female. The depression in female patients were significantly different from male patients (p< 0.05. GDS scores were significantly higher in group B patients (p< 0.05. There was a positive corelation between GDS scores and age (r= 0.648, p= 0.023 and female patients have had significantly higher GDS scores (p< 0.05. The adaptation to the treatment was significantly better in non-depressive patients (p< 0.05. There was a positive corelation between the hospital entrance number due to NC-SHF and GDS scores in all DSHF (r= 0.415, p< 0.05. On the other hand, there was a negative corelation between the EF and GDS scores (r= -0.307, p= 0.019.Conclusion: Depression is frequently seen in patients with DSHF. These patients should be carefully followed against psychiatric symptoms to give adequate treatment.

    Because it is safe and well tolerated, imatinib is a standard first-line therapy for chronic myeloid leukemia (CML). Although there have been sporadic reports of imatinib-induced cardiotoxicity, including left ventricle (LV) dysfunction and heart failure, the evidence for it is contradictory. Here, we reported a case of an 88-year-old male patient with CML developed decompensated heart failure following imatinib therapy. Four days after the initiation of imatinib, the patient developed orthopnea, edema and a pleural effusion accompanied by abdominal distension, nausea and vomiting. The chest X-ray film showed an enlarged cardiac profile. The echocardiogram demonstrated a decreased LV ejection fraction and enlarged left-side cardiac chambers. B-type natriuretic peptide concentrations were markedly increased. The patient recovered soon after the withdrawal of imatinib and introduction of comprehensive therapy for heart failure. Imatinib-induced cardiotoxicity in elderly patients is a potentially serious complication that merits further evaluation.

    Full Text Available Objective: Congestive heart failure (CHF has become one of the most important health care problems in western countries. This article focuses on the outpatient diagnosis and management of heart failure. We want to compare the outcome of patients who were treated with high dose diuretics in the emergency department (ED without admission with patients who were admitted to hospital for standard treatment. Methods: This was a randomized prospective clinical trial study. The patients who came to the ED from March 20, 2008 up to August 20, 2008 were divided into two groups randomly. The length of ED stay in the experimental group was documented. Also, readmission and mortality in 6 months and satisfaction in both groups were taken into consideration. All data were analyzed using SPSS 15.0. Results: In experimental group, the rate of recurrent admission, expiration, discharge, clinic visit, and clinic admission was 8%, 4%, 29%, 18%, and 0% respectively. On the other hand, in control group it was 16%, 40%, 18%, 22%, and 2% respectively. Additionally, there was a significant difference between these groups (P = 0.00. Conclusion: This study is the first regional prospective trial to comprehensively examine the therapeutic management in patients with CHF. This study, comparing the high dose diuretic efficacy in the decreasing of hospital stay and readmission; and decreasing mortality rate with routine therapy, showed that there was a significant difference between these two strategies in the mortality rate, readmission, and length of hospital stay (P = 0.00.

    To investigate the effects of levosimendan, a positive inotropic agent, on the new heart failure markers immunoglobulin free light chains kappa and lambda (FLC-kappa and FLC-lambda) in decompensated chronic heart failure (HF), 59 patients with New York Heart Association (NYHA) class III-IV HF were enrolled. Patients were randomized into levosimendan (n = 31) and standard HF treatment (n = 29) groups. Serum FLC-kappa and FLC-lambda, brain natriuretic peptide (BNP), and ejection fraction (EF) were measured before treatment and on the 5th day of treatment initiation. Forty-two percent of subjects were females (n = 25) and overall mean age was 64.1 +/- 10.7 years. FLC-kappa (P lambda (P kappa/FLC-lambda ratios in both groups were similar, whereas FLC-kappa and FLC-lambda levels and the FLC-kappa/FLC-lambda ratio showed no significant correlation with NYHA class, brain natriuretic peptide (BNP) and ejection fraction (EF) levels; and BNP and EF changes after the treatment. Symptomatic improvement in the levosimendan group according to the NYHA class was significantly better than in the standard treatment group (P = 0.044). While 55.2% of patients in the levosimendan group showed a 1-degree shift to lower NYHA classes, 10.3% showed a 2-degree decrease. In conclusion, levosimendan caused short-term hemodynamic and symptomatic improvements, with a more pronounced decrease in FLC levels in patients with advanced decompensated HF.

    Cardiorenal syndrome (CRS) is defined as an interaction of cardiac disease with renal dysfunction that leads to diuretic resistance and renal function worsening, mainly with heart failure (HF) exacerbation. Hemodynamic variables linking heart and kidney are renal blood flow (cardiac output) and perfusion pressure, i.e., the aortic - renal venous pressure gradient. CRS has traditionally been interpreted as related to defective renal perfusion and arterial underfilling and, more recently, to elevation in central venous pressure transmitted back to renal veins. Our suggestion is that in a setting where aortic pressure is generally low, due to heart dysfunction and to vasodrepressive therapy, the elevated central venous pressure (CVP) contributes to lower the renal perfusion pressure below the threshold of kidney autoregulation (≤80mm Hg) and causes renal perfusion to become directly pressure dependent. This condition is associated with high neurohumoral activation and preglomerular vasoconstriction that may preserve pressure, but may decrease filtration fraction and glomerular filtration rate and enhance proximal tubular sodium absorption. Thus, congestion worsens and drives the vicious cycle of further sodium retention and HF exacerbation. Lowering CVP by targeting the lung-right heart interaction that sustains elevated CVP seems to be a more rational approach rather than reducing intravascular volume. This interaction is crucial and consists of a cascade with stepwise development of pulmonary post-capillary hypertension, precapillary arteriolar hypertone, right ventricular overload and enlargement with tricuspid incompetence and interference with left ventricular filling (interdependence). The resultant CVP rise is transmitted to the renal veins, eventually drives CRS and leads to a positive feedback loop evolving towards HF refractoriness.

    Although hepatic encephalopathy (HE) on the background of acute on chronic liver failure (ACLF) is associated with high mortality rates, it is unknown whether this is due to increased blood-brain barrier permeability. Specific gravity of cerebrospinal fluid measured by CT is able to estimate blood-cerebrospinal fluid-barrier permeability. This study aimed to assess cerebrospinal fluid specific gravity in acutely decompensated cirrhosis and to compare it in patients with or without ACLF and with or without hepatic encephalopathy. We identified all the patients admitted for acute decompensation of cirrhosis who underwent a brain CT-scan. Those patients could present acute decompensation with or without ACLF. The presence of hepatic encephalopathy was noted. They were compared to a group of stable cirrhotic patients and healthy controls. Quantitative brain CT analysis used the Brainview software that gives the weight, the volume and the specific gravity of each determined brain regions. Results are given as median and interquartile ranges and as relative variation compared to the control/baseline group. 36 patients presented an acute decompensation of cirrhosis. Among them, 25 presented with ACLF and 11 without ACLF; 20 presented with hepatic encephalopathy grade ≥ 2. They were compared to 31 stable cirrhosis patients and 61 healthy controls. Cirrhotic patients had increased cerebrospinal fluid specific gravity (CSF-SG) compared to healthy controls (+0.4 %, p gravity did not differ between different brain regions according to the presence or absence of either ACLF or HE. In patients with acute decompensation of cirrhosis, and those with ACLF, CSF specific gravity is modified compared to both stable cirrhotic patients and healthy controls. This pattern is observed even in the absence of hepatic encephalopathy suggesting that blood-CSF barrier impairment is manifest even in absence of overt hepatic encephalopathy.

    Chronic liver disease is the fifth leading cause of death worldwide and represents a major burden for the health care community. Cirrhosis is a progressive disease resulting in end-stage liver failure, which in the absence of liver transplantation is fatal. Acute-on-chronic liver failure carries high short-term mortality but is potentially reversible. Viral hepatitis, alcohol, and nonalcoholic fatty liver disease remain the principal causes of liver disease. Though treatments exist for hepatitis B and C, they remain unavailable to many with these diseases. This article reviews the epidemiology of advanced liver disease and the concept of acute-on-chronic liver failure.

    Acute kidney injury (AKI) is an important clinical issue, especially in the setting of critical care. It has been shown in multiple studies to be a key independent risk factor for mortality, even after adjustment for demographics and severity of illness. There is wide agreement that a generally applicable classification system is required for AKI which helps to standardize estimation of severity of renal disfunction and to predict outcome associated with this condition. That's how RIFLE (Risk-Injury-Failure-Loss-End-stage renal disease), and AKIN (Acute Kidney Injury Network) classifications for AKI were found in 2004 and 2007, respectively. In the clinical setting of heart failure, a positive fluid balance (often expressed in the literature as weight gain) is used by disease management programs as a marker of heart failure decompensation. Oliguria is defined as urine output less than 0,3 ml/kg/h for at least 24 h. Since any delay in treatment can lead to a dangerous progression of the AKI, early recognition of oliguria appears to be crucial. Critically ill patients with oliguric AKI are at increased risk for fluid imbalance due to widespread systemic inflammation, reduced plasma oncotic pressure and increased capillary leak. These patients are particulary at risk of fluid overload and therefore restrictive strategy of fluid administration should be used. Objective, rapid and accurate volume assessment is important in undiagnosed patients presenting with critical illness, as errors may result in interventions with fatal outcomes. The historical tools such as physical exam, and chest radiography suffer from significant limitations. As gold standard, radioisolopic measurement of volume is impractical in the acute care enviroment. Newer technologies offer the promise of both rapid and accurate bedside estimation of volume status with the potential to improve clinical outcomes. Blood assessment with bioimpendance vector analysis, and bedside ultrasound seem to be

    Renal failure is a serious complication in patients with advanced cirrhosis. It occurs in about 20 % of patients hospitalized with cirrhosis. In about 70 % it is caused by prerenal failure, and in 30 % it is due to intrarenal causes. In about 70 % of patients with rperenal failure, renal function can be restored with fluid replacement, but the remaining 30 % are unresponsive to volume expansion. Minor increase in serum creatinine have been shown to be clinically relevant and can adversely affect survival. Therefore early efforts should be made to avoid precipitation of renal failure.Hepatorenal syndrome (HRS) is a  fully reversible impairment of renal function in patients with cirrhosis unresponsive to volume expansion characterized by an acute progressive decrease in kidney function (serumcreatinin > 1,5 mg/dl) - type 1 HRS, whereas type 2 HRS features a decrease in kidney function over a long time, mostly in patients with refractory ascites. Therapy with vasoconstrictors like terlipressin to reverse splanchnic vasodilation, together with albumin is effective in 30-50 % of patients with HRS 1 and improves survival. The only effective longterm therapy is livertransplantation. An improvement of kidney fuction before transplantation is associated with a better outcome and posttransplant kidney function.

  17. Loop diuretics in acute heart failure: beyond the decongestive relief for the kidney.

    Palazzuoli, Alberto; Ruocco, Gaetano; Ronco, Claudio; McCullough, Peter A

    2015-09-03

    Current goals in the acute treatment of heart failure are focused on pulmonary and systemic decongestion with loop diuretics as the cornerstone of therapy. Despite rapid relief of symptoms in patients with acute decompensated heart failure, after intravenous use of loop diuretics, the use of these agents has been consistently associated with adverse events, including hypokalemia, azotemia, hypotension, and increased mortality. Two recent randomized trials have shown that continuous infusions of loop diuretics did not offer benefit but were associated with adverse events, including hyponatremia, prolonged hospital stay, and increased rate of readmissions. This is probably due to the limitations of congestion evaluation as well as to the deleterious effects linked to drug administration, particularly at higher dosage. The impaired renal function often associated with this treatment is not extensively explored and could deserve more specific studies. Several questions remain to be answered about the best diuretic modality administration, global clinical impact during acute and post-discharge period, and the role of renal function deterioration during treatment. Thus, if loop diuretics are a necessary part of the treatment for acute heart failure, then there must be an approach that allows personalization of therapy for optimal benefit and avoidance of adverse events.

    replenish a compromised Krebs cycle and that this is a marker of compromised aerobic respiration within brain tissue. Thus there is a need for improved brain protective strategies during acute metabolic decompensations. MRS provides a non-invasive tool for which could be employed to evaluate novel treatments aimed at restoring basal ganglia homeostasis. The results from the liver transplantation sub-group supports the hypothesis that liver transplantation provides systemic metabolic stability by providing a hepatic pool of functional propionyl CoA carboxylase, thus preventing further acute decompensations which are associated with the risk of brain infarction.

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index 30 mmHg) and absent or reduced diuresis (< 0.5 ml/kg/h). The most common cause is left ventricular failure due to acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease.

    Cardiogenic shock remains a leading cause of mortality despite advances in the treatment of myocardial infarction and advanced heart failure. Medical therapy can be inadequate, and patients may need mechanical circulatory support (MCS). The proper application of MCS requires knowledge of the underlying cause of acute heart failure, familiarity with the circulatory support devices, and the potential benefits and limitations of device therapy. This article describes the most commonly used temporary ventricular assist devices and their use in the various causes of cardiogenic shock.

Chronic hyporeninemic hypoaldosteronism has been found in many cases of methylmalonic acidemia, hyperkalemia and renal tubular acidosis type 4. We report 2 patients affected by B12-unresponsive methylmalonic acidemia diagnosed at the age of 23 months and 5 years, respectively, with normal glomerular filtration and function. They showed hyporeninemic hypoaldosteronism and significant hyperkalemia requiring sodium potassium exchange resin (Kayexalate) therapy after an episode of metabolic decompensation leading to diagnosis of MMA. In both children, hyporeninemic hypoaldosteronism and hyperkalemia disappeared after 6 months of good metabolic control.

    This study sought to assess the relationship between serum concentrations of the soluble ST2 (sST2) and B-type natriuretic peptide (BNP) and investigate the role of sST2 as a prognosticator in patients hospitalized with acute heart failure (HF) and renal insufficiency. sST2 was measured at admission and discharge in 66 patients hospitalized with acute decompensated HF and renal insufficiency (estimated glomerular filtration rate [eGFR] renal insufficiency (eGFR renal function, even though BNP level was much higher in patients with severe renal insufficiency. During 3 month follow-up, 9 (13.6%) died and 16 (24.2%) were readmitted due to HF aggravation.On multivariate analysis, sST2 at discharge was independently associated with death or HF readmission during 3 months after discharge (hazard ratio, 1.038; 95% confidence interval, 1.011-1.066, P = 0.006). In conclusion, sST2 is not affected by renal function compared with BNP in acute HF patients. The measurement of predischarge sST2 can be helpful in predicting short-term outcomes in acute decompensated HF patients with renal insufficiency.

    Objectives This study addressed to compare plasma B-type natriuretic peptide (BNP) and endothelin-1 (ET-l) levels with hemodynamics in heart failure (HF) patients. Methods Plasma BNP and ET-1 levels were obtained from 75patients with HF by rapid immunofluorescence assay and radio-immunity method, respectively, and left ventricular end-diastolic diameter (LVEDD) were observed by echocardiogram. Hemodynamic data of 53HF patients were determined by Swan-Ganz catheterization. Results Hemodynamics (PCWP,MPAP and RAP) and plasma BNP, ET-1 levels were proportional to New York Heart Association (NYHA)class (P< 0.001-0.05). Both BNP and ET-1 had positive linear relations with PCWP, MPAP, RAP (P< 0.05-001). Moreover, plasma ET-1 was an independent and significant predictor of BNP (P<0.001). Plasma levels of BNP (968.23±478.63 pg/ml)and ET-1 (129.45±88.56 pg/ml)in group with LVEDD (n=31) ≥60 mm were much higher than those in LVEDD(n = 44) < 60mm group (BNP:286.26 ±156.89 pg/mL,ET-1:87.45±43.65 pg/mL, P< 0.001). Conclusions BNP level is as a direct result of ventricular volume expansion and pressure overload. BNP is a sensitive biochemical maker of left ventricular injury and ET-1may stimulate the secretion of cardiac BNP independent of hemodynamics in patients with HF.

    Managing patients with heart failure (HF) is a challenging task within itself, but the presence of associated worsening renal function can greatly increase mortality and morbidity. Early diagnosis and treatment is the key to prevent re-hospitalizations and reduce healthcare costs. Biomarkers have long been established as highly sensitive and specific tools in diagnosing and prognosticating patients with HF. Reflecting distinct pathophysiological events and ongoing cellular insult, biomarkers have been proven superior to conventional laboratory tests. Availability of better assays and rapid analysis has allowed the use of biomarkers as point-of-care tests in the emergency department and at the patient's bed-side. Acute HF patients often go on to develop worsening renal function, termed as acute cardiorenal syndrome. The growing breadth of studies has shown the implications of combining multiple biomarkers to better chart outcomes and produce desirable results in such patients.

    Full Text Available Neurohumoral model of pathogenesis of chronic heart failure (CHF made it possible to develop new therapeutic approaches in patients with CHF . However , it became obvious that the ways of activation of neurohumoral systems in CHF are much more complicated. The increase in local synthesis of hormones causes the activation of inflammatory cytokines and protooncogenes, which have various negative effects. This allowed formulating immunoinflammatory conception of CHF pathogenesis, according to which the increase in interleukine-6 blood level is the marker of unfavorable prognosis for CHF , and the level of tumor necrosis factor-α (TNF-α straightly correlates with severity of clinical condition and neurohumoral activity in CHF . The growth of TNF-α in CHF progressing as well as its reduction in successful treatment do not exclude the probability of positive effect of therapy , focused on the reduction of TNF-α concentration. The pathogenesis peculiarities of CHF including cytokine aggression demand the necessity of development of new therapy approaches with the use of cytokine system modulators.

    The pathophysiological interactions that link the heart and kidney in heart failure are multiple and complex. This issue constitutes one of the most vexing and difficult challenges facing cardiologists. In the setting of acute decompensated heart failure, worsening renal function has traditionally been directly associated with poor clinical prognosis and complicates treatment. In the last years, many reports suggest that worsening renal failure may represent the final common pathway of several mechanistically distinct processes, with different prognostic implications. In the clinical scenario, the clinical significance of transient worsening of renal function may be different as compared with irreversible or progressive renal failure. In addition, it can represent a relatively normal response to treatment-induced physiological derangements such as a reduction in renal perfusion and/or intravascular volume. We here focus on these highlights, with special reference to the diagnostic criteria of renal dysfunction and the management of fluid overload. Two expert nephrologists were asked to answer a few important clinical questions: how should renal dysfunction be recognized and monitored? Are there therapies to counteract it and when, and more importantly, for whom should be applied? Their answers serve as touchstones for cardiologists to provide better individualized care for their patients with acute heart failure. Only a multidisciplinary and collaborative management of cardio-renal interactions will help to mitigate the difficult day-to-day clinical practice and improve our understanding of this condition through a concerted and constructive approach.

    Congestive heart failure(CHF) is one of the most common reasons for hospitalization in the United States. Despite multiple different beneficial medications for the treatment of chronic CHF, there are no therapies with a demonstrated mortality benefit in the treatment of acute decompensated heart failure. In fact, studies of inotropes used in this setting have demonstrated more harm than good. Arginine vasopressin has been shown to be up regulated in CHF. When bound to the V1 a and/or V2 receptors, vasopressin causes vasoconstriction, left ventricular remodeling and free water reabsorption. Recently, two drugs have been approved for use that antagonize these receptors. Studies thus far have indicated that these medications, while effective at aquaresis(free water removal), are safe and not associated with increased morbidity such as renal failure and arrhythmias. Both conivaptan and tolvaptan have been approved for the treatment of euvolemic and hypervolemic hyponatremia. We review the results of these studies in patients with heart failure.

    Full Text Available Mortality from acute respiratory distress syndrome (ARDS has gone down recently. In spite of this trend, the absolute numbers continue to be high even with improvements in ventilator strategies and a better understanding of fluid management with this disease. A possible reason for this could be an under-recognized involvement of the pulmonary vasculature and the right side of the heart in ARDS. The right heart is not designed to function under situations leading to acute elevations in afterload as seen in ARDS, and hence it decompensates. This brief review focuses on the magnitude of the problem, its detection in the intensive care unit, and recognizes the beneficial effect of prone-positioning on the pulmonary vasculature and right heart.

    Objectives To study the monitoring of rejection after orthotopic heart thansplantation.Methods From 1998 to 2005, 10 othotopic heart thansplans were performed, and acute rejection was monitored by endomyocardial biopsy as well as by clinical features, ECG, ultrasonocardiography and blood serum determination of Tropin I, and by the combination of these methods, we analysed the monitoring of acute rejection after the heart transplantation. Results With the combination of clinical features, ECG, ultrasonocardiography and blood serum test, 5 occurences of acute rejection were judged in the postoperative course, which were comfirmed by endomyocardial biopsy to be 2 acute rejections in Ⅰ b degree, 3 acute rejections in Ⅲ a degree. Endomyocardial biopsy were routinely performed 21 times postoperatively in which there were 1 acute rejection in Ⅰ a degree and 5 acute rejections in Ⅰ b degree. Conclusions Acute rejection is an important factor influencing the postoperative course of heart transplantation, so it is imperative to have an intime, effective and planned monitoring procedure for acute rejection. Endomyocardial biopsy is a sensitive and reliable method in diagnosis of acute rejection, but it is invasive and probable for some complications. The noninvasive method such as clinical features, ECG,ultrasonocardiography and blood serum test can be used as additive means in the diagnosis of acute rejection.Endomyocardial biopsy should be combined with some noninvasive methods in monitoring acute rejection after the heart transplantation.

    Full Text Available Background. Diuresis is a major therapy for the reduction of congestive symptoms in acute decompensated heart failure (ADHF patients. We previously reported the efficacy and safety of tolvaptan compared to carperitide in hospitalized patients with ADHF. There were some reports of cardio- and renal-protective effects in carperitide; therefore, the purpose of this study was to compare the long-term effects of tolvaptan and carperitide on cardiorenal function and prognosis. Methods and Results. One hundred and five ADHF patients treated with either tolvaptan or carperitide were followed after hospital discharge. Levels of plasma B-type natriuretic peptide, serum sodium, potassium, creatinine, and estimated glomerular filtration rate were measured before administration of tolvaptan or carperitide at baseline, the time of discharge, and one year after discharge. These data between tolvaptan and carperitide groups were not different one year after discharge. Kaplan-Meier survival curves demonstrated that the event-free rate regarding all events, cardiac events, all cause deaths, and rehospitalization due to worsening heart failure was not significantly different between tolvaptan and carperitide groups. Conclusions. We demonstrated that tolvaptan had similar effects on cardiac and renal function and led to a similar prognosis in the long term, compared to carperitide.

    Acute heart failure is defined as the acute onset of symptoms due to hear failure necessitating emergency therapy. The in-hospital mortality rate ranges up to 10 % and in cardiogenic shock is 50-70 %. In acute heart failure, rapid diagnosis and causal therapy are necessary to avoid cardiogenic shock. In cases of acute coronary syndromes, primary percutaneous intervention should be performed immediately. Medical and apparative treatment strategies focus on decreasing pulmonary congestion, afterload, and neurohormonal activation in order to improve hemodynamics and reduce symptoms of dyspnea. In contrast to chronic heart failure, no medical therapy has been able to reduce mortality rates in acute heart failure. However, new medical therapies should at least improve clinical symptoms of congestion and favorably reduce cardiovascular events, re-hospitalization, and mortality rates.

    Acute rheumatic fever (ARF) is the result of an autoimmune response to pharyngitis caused by infection with group A Streptococcus. The long-term damage to cardiac valves caused by ARF, which can result from a single severe episode or from multiple recurrent episodes of the illness, is known as rheumatic heart disease (RHD) and is a notable cause of morbidity and mortality in resource-poor settings around the world. Although our understanding of disease pathogenesis has advanced in recent years, this has not led to dramatic improvements in diagnostic approaches, which are still reliant on clinical features using the Jones Criteria, or treatment practices. Indeed, penicillin has been the mainstay of treatment for decades and there is no other treatment that has been proven to alter the likelihood or the severity of RHD after an episode of ARF. Recent advances - including the use of echocardiographic diagnosis in those with ARF and in screening for early detection of RHD, progress in developing group A streptococcal vaccines and an increased focus on the lived experience of those with RHD and the need to improve quality of life - give cause for optimism that progress will be made in coming years against this neglected disease that affects populations around the world, but is a particular issue for those living in poverty.

    Full Text Available Obesity is clearly associated with increased morbidity and mortality rates. However, in patients with acute heart failure (AHF, an increased BMI could represent a protective marker. Studies evaluating the "obesity paradox" on a large cohort with long-term follow-up are lacking.Using the AHEAD database (a Czech multi-centre database of patients hospitalised due to AHF, 5057 patients were evaluated; patients with a BMI 25 kg/m2. Data were adjusted by a propensity score for 11 parameters.In the balanced groups, the difference in 30-day mortality was not significant. The long-term mortality of patients with normal weight was higher than for those who were overweight/obese (HR, 1.36; 95% CI, 1.26-1.48; p<0.001. In the balanced dataset, the pattern was similar (1.22; 1.09-1.39; p<0.001. A similar result was found in the balanced dataset of a subgroup of patients with de novo AHF (1.30; 1.11-1.52; p = 0.001, but only a trend in a balanced dataset of patients with acute decompensated heart failure.These data suggest significantly lower long-term mortality in overweight/obese patients with AHF. The results suggest that at present there is no evidence for weight reduction in overweight/obese patients with heart failure, and emphasize the importance of prevention of cardiac cachexia.

    2005-01-01

    Pulmonary arterial hypertension complicated by decompensated cor pulmonale is a challenging clinical problem with few effective therapeutic options. B-type natriuretic peptide is a pluripotent hormone that promotes diuresis and natriuresis, vasodilates systemic and pulmonary vessels, and reduces circulating levels of endothelin and aldosterone. It may represent a possible therapeutic strategy for decompensated cor pulmonale in the same manner that it is used to treat decompensated left heart failure. The authors report their experience with B-type natriuretic peptide as adjunctive therapy for pulmonary arterial hypertension complicated by decompensated cor pulmonale. A detailed case report is presented followed by the evaluation of a series of 11 cases occurring in eight patients from December 2002 through April 2004.

    Full Text Available Background: Prospective comparative studies to predict the risk of hemodynamic deterioration in patients referred for transplantation were performed on the basis of standard invasive and non-invasive data and new wave intensity (WI parameters. Methods and results: Study Group 1 consisted of 151 consecutive outpatients (age 48.7 ± 12 years; 110 men with end-stage dilative cardiomyopathy. Group 2, consisting of 11 consecutive patients (age 50 ± 11 years; 6 men with sinus rhythm and “true” decompensation, was used to create “critical values” of WI. There were no demographic or somatic (weight and height differences between the groups. The follow-up period of ambulatory patients was 31 ± 8 months. Non-invasive WI was studied in the common carotid artery. Complete invasive and non-invasive data were also recorded on the day of investigation. During follow-up 44 pts were lost; there were 15 cardiac deaths (10%, life-saving ventricular assist device implantation in 10 (6.6% and transplantation in 19 (12.7%. For statistical purposes this group was named the “events” Group B (n = 44. A predisposing factor for events (death, “true” decompensation and “urgent” transplantation in ambulatory patients was low first peak (“cut-off value” assessed in Group 2 < 4100 mmHg*s³ (OR 45.6, CI 14.5–143.3, p < 0.001. Less powerful predictors of the risk of deterioration were pulmonary capillary pressure (PCP, diastolic pulmonary artery pressure (PAP and E/A mitral wave relation (p = 0.05. Conclusions: The new ventricular-arterial coupling parameter 1st peak of WI can potentially be used to distinguish patients at high risk for true deterioration and death. This parameter can be used to predict the need for assist device implantation.

    Full Text Available Mortality in cirrhosis is consequent of decompensation, only treatment being timely liver transplantation. Organ allocation is prioritized for the sickest patients based on Model for End Stage Liver Disease (MELD score. In order to improve survival in patients with high MELD score it is imperative to preserve them in suitable condition till transplantation. Here we examine means to prolong life in high MELD score patients till a suitable liver is available. We specially emphasize protection of airways by avoidance of sedatives, avoidance of Bilevel Positive Airway Pressure, elective intubation in grade III or higher encephalopathy, maintaining a low threshold for intubation with lesser grades of encephalopathy when undergoing upper endoscopy or colonoscopy as pre transplant evaluation or transferring patient to a transplant center. Consider post-pyloric tube feeding in encephalopathy to maintain muscle mass and minimize risk of aspiration. In non intubated and well controlled encephalopathy, frequent physical mobility by active and passive exercises are recommended. When renal replacement therapy is needed, night-time Continuous Veno-Venous Hemodialysis may be useful in keeping the daytime free for mobility. Sparing and judicious use of steroids needs to be borne in mind in treatment of ARDS and acute hepatitis from alcohol or autoimmune process.

Cirrhosis is a major cause of morbidity and mortality in the USA, and according to the Centers for Disease Control and Prevention was responsible for 31,903 deaths in 2010 alone. It is thus of the utmost importance to appropriately manage these patients in the inpatient and outpatient setting to improve morbidity and mortality. In this review, we address four major areas of cirrhosis management: outpatient management of portal hypertension with decompensation, hepatic encephalopathy, hepatorenal syndrome, and bleeding/coagulation issues. Outpatient management covers recommendations for health care maintenance and screening. Hepatic encephalopathy encompasses a brief review of pathophysiology, treatment in the acute setting, and long-term prevention. Hepatorenal syndrome is discussed in regards to pathophysiology and treatment in the hospital setting. Finally, a discussion of the assessment of coagulation profiles in cirrhosis and recommendations for bleeding and thrombosis complications is included. These topics are not all encompassing with regard to this complicated population, but rather an overview of a few medical problems that are commonly encountered in their care.

    Full Text Available Chagas disease is transmitted by the parasite, Trypanosoma cruzi. Acute infection is characterized by acute myocarditis, although it is largely asymptomatic. Initial cardiac insult could be a determinant to the posterior development of chronic Chagasic cardiomyopathy, usually after 10 years in only approximately 30% of chronically infected patients. Herein, we characterized the acute gene expression profiling in heart tissue of two strains of mice infected with T. cruzi (tulahuen strain at 4 weeks and their respective controls. Gene sequence data are available at NCBI under GEO accession number: GSE63847. The output of the genes expression suggests differences in involvement of protein kinase B (AKT, NCAM1, HLA-DRA, and ubiquitin C genes networks. These gene activation differences may correlate with myocardial contractility during the acute infection.

    Acute rheumatic fever and rheumatic heart disease are diseases of socioeconomic disadvantage. These diseases are common in developing countries and in Indigenous populations in industrialized countries. Clinicians who work with Indigenous populations need to maintain a high index of suspicion for the potential diagnosis of acute rheumatic fever, particularly in patients presenting with joint pain. Inexpensive medicines, such as aspirin, are the mainstay of symptomatic treatment of rheumatic fever; however, antiinflammatory treatment has no effect on the long-term rate of progression or severity of chronic valvular disease. The current focus of global efforts at prevention of rheumatic heart disease is on secondary prevention (regular administration of penicillin to prevent recurrent rheumatic fever), although primary prevention (timely treatment of streptococcal pharyngitis to prevent rheumatic fever) is also important in populations in which it is feasible.

    Ivabradine is a heart rate reducing agent that exhibits anti-ischemic effects through the inhibition of funny electrical current in the sinus node resulting in heart rate reduction, thus enabling longer diastolic perfusion time, and reduced myocardial oxygen consumption without detrimental changes in arterial blood pressure, coronary vasomotion, and ventricular contractility. The current guideline-based clinical use of Ivabradine is reserved for patients with stable angina pectoris who cannot tolerate or whose symptoms are inadequately controlled with beta blockers. In patients with chronic heart failure and reduced ejection fraction, Ivabradine has demonstrated beneficial effects in improving clinical outcomes when added to conventional therapy. However, the role of Ivabradine in acute coronary syndromes has not been established. Based on the results from some relevant preclinical studies and a limited amount of clinical data that were reported recently, the role of Ivabradine in acute ischemic events warrants further investigation. The aim of this review is to provide an overview of the available literature on the potential role of Ivabradine in the clinical context of acute coronary syndromes.

    After transplantation of nonrenal solid organs, an acute decline in kidney function develops in the majority of patients. In addition, a significant number of nonrenal solid organ transplant recipients develop chronic kidney disease, and some develop end-stage renal disease, requiring renal replacement therapy. The incidence varies depending on the transplanted organ. Acute kidney injury after nonrenal solid organ transplantation is associated with prolonged length of stay, cost, increased risk of death, de novo chronic kidney disease, and end-stage renal disease. This overview focuses on the risk factors for posttransplant acute kidney injury after liver and heart transplantation, integrating discussion of proteinuria and chronic kidney disease with emphasis on pathogenesis, histopathology, and management including the use of mechanistic target of rapamycin inhibition and costimulatory blockade.

    We report a case of acute tamponade of the left paracorporeal pump house in a patient supported by a Berlin Heart EXCOR biventricular assist device (BiVAD) caused by mechanical defect in the membrane of the arterial chamber. A 36-year old male was admitted for composite graft surgery due to a large aortic regurgitation and consecutive heart failure, decompensated postoperatively and was rescued by with an extracorporeal membrane oxygenation (ECMO) device. He was accepted for heart transplantation, and a BiVAD (Berlin Heart EXCOR) was implanted as bridge-to-transplantation. Two months after discharge, he experienced dyspnoea and received error signals from his BiVAD. Relatives released him from his BiVAD companion driver, connected him to the hand pump and transported him to our institution. On arrival, he was in cardiogenic shock and was stabilized by ECMO. Inspection of the arterial chamber revealed a wear hole and delamination of the diaphragm, which had led to a tamponade by air insufflation into the three-layer membrane. New BiVAD paracorporeal pumps were connected, and the patient was subsequently successfully transplanted. The case depicts the difficulty of diagnosis in this specific patient setting. Despite transparent design of the BiVAD chambers, the development of a chamber tamponade remained undetected until explantation of the system.

    Full Text Available Heart failure becomes main problem in cardiology because of increasing of heart failure patients, rehospitalization rate, morbidity, and mortality rate. The main causes of increasing heart failure problems are: (1 Successful treatment of acute myocardial infarction can be life saving, but its sequelae can cause heart failure. (2 Increasing life expectancy rate grows along with incidences of ageing related heart failure. (3 High prevalence of infection in Indonesia can cause rheumatic heart disease post Streptococcal beta hemolyticus infection, viral myocarditis, infective endocartitis, and tuberculoid pericarditis. (4 Many risk factors for coronary heart disease are often found in heart failure patients, for examples smoking, diabetes, hypercholesterolemia, hypertension, and obesity. Indonesia joined international multicentered registry in 2006. Acute Decompensated HEart failure REgistry is a web based international registry to record patient with acute decompensated heart failure treated in emergency room. It was found that heart failure patients in 5 big hospitals in Java and Bali island that joined this registry are younger, sicker and late to seek treatment. The median hospital length of stay was 7 days and in hospital mortality rate was 6.7%. The aim of this article is to give summary about essential things in diagnosing and treating heart failure patients. 3D (accurate diagnoses, evidence based drugs, and new devices are the most important but what to do and what not to do in dealing with heart failure is also useful for your daily practice.

  18. Novel biomarkers in acute heart failure: MR-pro-adrenomedullin.

    Science.gov (United States)

    Peacock, W Frank

    2014-10-01

    First isolated from human pheochromocytoma cells, adrenomedullin (ADM) is a peptide hormone with natriuretic, vasodilatory, and hypotensive effects mediated by cyclic adenosine monophosphate (cAMP), nitric oxide, and renal prostaglandin systems. ADM expression occurs in many tissues and organ systems, including cardiovascular, renal, pulmonary, cerebrovascular, gastrointestinal, and endocrine tissues where it acts as a circulating hormone and a local autocrine and paracrine hormone. ADM plasma concentrations are increased in hypertension, chronic renal disease, and heart failure. As ADM is unstable in vitro, it is necessary to measure its mid-regional pro-hormone fragment, the levels of which correspond to ADM concentration (MR-proADM). The prognostic potential of MR-proADM was recently demonstrated in the Biomarkers in Acute Heart Failure (BACH) trial. In this trial of 568 acute heart failure patients, MR-proADM was superior to both brain natriuretic peptide (BNP) and NT-proBNP in predicting mortality within 14 days. MR-proADM also provided significant additive incremental predictive value for 90-day mortality when added to BNP and NT-proBNP.

    2014-09-01

    In patients with acute heart failure (AHF) syndromes, little data are so far available on the relation between glucose values and insulin resistance and mortality, both in the short and long term. The present review is aimed at summarizing available evidence on the prognostic role of hyperglycemia in acute heart failure syndromes. Despite the fact that glucose values are widely measured, inexpensive, and easy to interpret, hyperglycemia in AHF patients still appears to be (or at least to have been) a neglected factor. Scarce information is available on incidence of admission hyperglycemia (especially in nondiabetic AHF patients) and data on in-hospital and discharge glucose values are lacking. Overall, the scarcity of data and the unanswered questions conjure up the need for trials investigating the clinical and prognostic role of glucose abnormalities (hyperglycemia and acute insulin resistance) on admission and during hospital stay in AHF patients. Preliminary evidence suggests that hyperglycemia is an important prognostic factor in AHF; however, whether targeting hyperglycemia via an aggressive versus permissive glycemic management strategy influences AHF outcomes remains unknown.

    Full Text Available Abstract Introduction Hyperthyroidism is a well established cause of atrial fibrillation (AF. Thyroid Stimulating Hormone-secreting pituitary tumours are rare causes of pituitary hyperthyroidism. Whilst pituitary causes of hyperthyroidism are much less common than primary thyroid pathology, establishing a clear aetiology is critical in minimising complications and providing appropriate treatment. Measuring Thyroid Stimulating Hormone (TSH alone to screen for hyperthyroidism may be insufficient to appropriately evaluate the thyroid status in such cases. Case presentation A 63-year-old Caucasian man, previously fit and well, presented with a five-day history of shortness of breath associated with wheeze and dry cough. He denied symptoms of hyperthyroidism and his family, social and past history were unremarkable. Initial investigation was in keeping with a diagnosis of atrial fibrillation (AF with fast ventricular response leading to cardiac decompensation. TSH 6.2 (Normal Range = 0.40 – 4.00 mU/L, Free T3 of 12.5 (4.00 – 6.8 pmol/L and Free T4 51(10–30 pmol/L. Heterophilic antibodies were ruled out. Testosterone was elevated at 43.10 (Normal range: 10.00 – 31.00 nmol/L with an elevated FSH, 18.1 (1.0–7.0 U/L and elevated LH, 12.4 (1.0–8.0 U/L. Growth Hormone, IGF-1 and prolactin were normal. MRI showed a 2.4 cm pituitary macroadenoma. Visual field tests showed a right inferotemporal defect. While awaiting neurosurgical removal of the tumour, the patient was commenced on antithyroid medication (carbimazole and maintained on this until successful trans-sphenoidal excision of the macroadenoma had been performed. AF persisted post-operatively, but was electrically cardioverted subsequently and he remains in sinus rhythm at twelve months follow-up off all treatment. Conclusion This case reiterates the need to evaluate thyroid function in all patients presenting with atrial fibrillation. TSH-secreting pituitary adenomas must be considered

    There have been numerous reports in the literature on the descriptive similarities between a severe nightmare and an acute psychotic episode. Nightmares may be a prelude to psychotic decompensation, and it has been suggested that frequent lifelong nightmares may even be diagnostic of an underlying vulnerability to psychosis. In this report, we present a case study of a 40-year old female experiencing chronic paranoid schizophrenia, whose two witnessed psychotic relapses in the hospital were immediately preceded by intense and vivid nightmare attacks. Significantly, the content of these nocturnal dreams was thematically consistent with her waking hallucinations, suggesting a direct continuity between these experiences. We propose that further systematic study of the dreams and nightmares of individuals diagnosed with schizophrenia may be particularly useful in understanding their phenomenological experience.

    Full Text Available Patients with decompensated liver cirrhosis have significantly impaired synthetic function. Many proteins involved in the coagulation process are synthesized in the liver. Routinely performed tests of the coagulation are abnormal in patients with decompensated liver cirrhosis. This has led to the widespread belief that decompensated liver cirrhosis is prototype of acquired hemorrhagic coagulopathy. If prothrombin time is prolonged more than 3 seconds over control, invasive procedures like liver biopsy, splenoportogram, percutaneous cholangiography, or surgery were associated with increased risk of bleeding, and coagulopathy should be corrected with infusion of fresh frozen plasma. These practices were without any scientific evidence and were associated with significant hazards of fresh frozen plasma transfusion. Now, it is realized that coagulation is a complex process involving the interaction of procoagulation and anticoagulation factors and the fibrinolytic system. As there is reduction in both anti and procoagulant factors, global tests of coagulation are normal in patients with acute and chronic liver disease indicating that coagulopathy in liver disease is more of a myth than a reality. In the last few years, surgical techniques have substantially improved, and complex procedures like liver transplantation can be done without the use of blood or blood products. Patients with liver cirrhosis may also be at increased risk of thrombosis. In this paper, we will discuss coagulopathy, increased risk of thrombosis, and their management in decompensated liver cirrhosis.

    The expression and changes of local cytokines network were detected in heart transplantation in rats, so as to determine the role of cytokines in the acute rejection of rats of heart transplantation. Allografts were divided into 4 groups (n=12 in each group): group A (control), group B (IL-2 monoclonal antibody-treated), group C (CsA-treated) and group D (IL-2 monoclonal antibody+CsA-treated). Hearts from DA rats were transplanted into a cervical location in Wistar recipients. The local expression of IL-1β, IL-2, CD25, IL-4, IL-5, IL-6, IL-10, TNFα and INFγ was detected at day 1, 3, 5, 7, 9, 11 and 14 by reverse transcription polymerase chain reaction. The results showed that the survival time of allografts was 8.3±1.7, 29.2±7.1 (P<0.05), 26.4±5.7 (P<0.05) and 55.0±10.6 (P<0.01) days respectively in groups A, B, C and D. The expression of IL-1β, IL-4, IL-10and IFNγ was up-regulated, and that of IL-2, CD25, IL-5, IL-6 and TNFα was significantly inhibited in group A; The expression of IL-1β, IL-5, IL-6, IL-10 and IFNγ was up-regulated, and that of IL-2,IL-4 and TNFα was significantly down-regulated in group B; The expression of IL-1β, IL-2, CD25,IL-5, TNFα and IFNγ was up-regulated, and that of IL-4, IL-6 and IL-10 was significantly down-regulated in group C; The expression of IL-14, Il-5, IL-6 and Il-10 was up-regulated, and that of IL-1β, IL-2, CD25, TNFα and IFNγ was significantly down-regulated in group D. In conclusion,cytokines play an important role in the development of acute transplantation rejection. Different cytokines play different roles in different local environments.

    2011-01-01

    Full Text Available We report two cases of young men in whom acute heart failure due to myocarditis was diagnosed. The patients had been transferred to the intensive care unit (ICU with commencing symptoms of acute heart failure and consecutive multiorgan failure for further treatment and to evaluate the indication for implantation of a ventricular assist device or for high urgent orthotopic heart transplantation. In both patients, the If-channel inhibitor ivabradine was administered off-label to provide selective heart rate reduction, and thus support hemodynamic stabilization. Though currently considered off-label use in patients suffering from severe hypotension and acute heart failure, the use of ivabradine may beneficially influence outcome by allowing optimization of the patient's heart rate concomitant to initial measures of clinical stabilization.

    Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for heart failure (HF). Although some progress has been made in improving survival among patients admitted for HF, the rates of hospital readmissions and the related costs continue to rise dramatically. We sought to examine whether NAFLD and its severity (diagnosed at hospital admission) was independently associated with a higher risk of 1-year all-cause and cardiac re-hospitalization in patients admitted for acute HF. We studied 212 elderly patients who were consecutively admitted with acute HF to the Hospital of Negrar (Verona) over a 1-year period. Diagnosis of NAFLD was based on ultrasonography, whereas the severity of advanced NAFLD fibrosis was based on the fibrosis (FIB)-4 score and other non-invasive fibrosis scores. Patients with acute myocardial infarction, severe valvular heart diseases, end-stage renal disease, cancer, known liver diseases or decompensated cirrhosis were excluded. Cox regression was used to estimate hazard ratios (HR) for the associations between NAFLD and the outcome(s) of interest. The cumulative rate of 1-year all-cause re-hospitalizations was 46.7% (n = 99, mainly due to cardiac causes). Patients with NAFLD (n = 109; 51.4%) had remarkably higher 1-year all-cause and cardiac re-hospitalization rates compared with their counterparts without NAFLD. Both event rates were particularly increased in those with advanced NAFLD fibrosis. NAFLD was associated with a 5-fold increased risk of 1-year all-cause re-hospitalization (adjusted-hazard ratio 5.05, 95% confidence intervals 2.78–9.10, pacute HF. PMID:28288193

    Acute rheumatic fever is a nonsuppurative, immune-mediated consequence of group A streptococcal pharyngitis (strep throat). Recurrent or severe acute rheumatic fever can cause permanent cardiac valve damage and rheumatic heart disease, which increases the risk for cardiac conditions (e.g., infective endocarditis, stroke, and congestive heart failure). Antibiotics can prevent acute rheumatic fever if administered no more than 9 days after symptom onset. Long-term benzathine penicillin G (BPG) injections are effective in preventing recurrent acute rheumatic fever attacks and are recommended to be administered every 3-4 weeks for 10 years or until age 21 years to children who receive a diagnosis of acute rheumatic fever. During August 2013, in response to anecdotal reports of increasing rates of acute rheumatic fever and rheumatic heart disease, CDC collaborated with the American Samoa Department of Health and the Lyndon B. Johnson Tropical Medical Center (the only hospital in American Samoa) to quantify the number of cases of pediatric acute rheumatic fever and rheumatic heart disease in American Samoa and to assess the potential roles of missed pharyngitis diagnosis, lack of timely prophylaxis prescription, and compliance with prescribed BPG prophylaxis. Using data from medical records, acute rheumatic fever incidence was calculated as 1.1 and 1.5 cases per 1,000 children aged ≤18 years in 2011 and 2012, respectively; 49% of those with acute rheumatic fever subsequently received a diagnosis of rheumatic heart disease. Noncompliance with recommended prophylaxis with BPG after physician-diagnosed acute rheumatic fever was noted for 22 (34%) of 65 patients. Rheumatic heart disease point prevalence was 3.2 cases per 1,000 children in August 2013. Establishment of a coordinated acute rheumatic fever and rheumatic heart disease control program in American Samoa, likely would improve diagnosis, treatment, and patient compliance with BPG prophylaxis.

    Acute passive fixation atrial lead dislodgment occurred due to an unexpected and marked postural descent of the heart after permanent pacemaker implantation in two patients. Sagging of the heart in these two individuals may have been related to a history of morbid obesity followed by weight loss of over 100 pounds. Lead replacement with active fixation leads was required in both cases. The term "sagging heart syndrome" is proposed to describe this clinical entity. In certain adult populations, such as in patients with a history of significant weight loss, the "sagging heart syndrome" may represent a previously unrecognized cause of acute lead dislodgment.

    Nitrates are potent venous dilators and anti-ischemic agents. They are widely used for the relief of chest pain and pulmonary congestion in patients with acute coronary syndromes and heart failure. Nitrates, however, do not reduce mortality in patients with acute coronary syndromes. Combination of nitrates and hydralazine when given in addition to beta-blockers and angiotensin-converting enzyme (ACE) inhibitors reduce mortality and heart failure hospitalizations in patients with heart failure due to left ventricular systolic dysfunction who are of African-American origin. Side effects during nitrate therapy are common but are less well described in the literature compared with the reported side effects in patients with stable angina pectoris. The reported incidence of side effects varies highly among different studies and among various disease states. Headache is the most commonly reported side effect with an incidence of 12% in acute heart failure, 41-73% in chronic heart failure, 3-19% in unstable angina and 2-26% in acute myocardial infarction. The reported incidence of hypotension also differs: 5-10% in acute heart failure, 20% in chronic heart failure, 9% in unstable angina and < 1-48% in acute myocardial infarction, with the incidence being much higher with concomitant nitrate therapy plus angiotensin-converting enzyme inhibitors. Reported incidence of dizziness is as low as 1% in patients with acute myocardial infarction to as high as 29% in patients with heart failure. Severe headaches and/or symptomatic hypotension may necessitate discontinuation of nitrate therapy. Severe life threatening hypotension or even death may occur when nitrates are used in patients with acute inferior myocardial infarction associated with right ventricular dysfunction or infarction, or with concomitant use of phosphodiesterase-5 inhibitors or N-acetylcysteine. Despite the disturbing observational reports in the literature that continuous and prolonged use of nitrates may lead to

    Nanog is a potential stem cell marker and is considered a regeneration factor during tissue repair. In the present study, we investigated expression patterns of nanog in the rat heart after acute myocardial infarction by semi-quantitative RT-PCR, immunohistochemistry and Western blot analyses. Our results show that nanog at both mRNA and protein levels is positively expressed in myocardial cells, fibroblasts and small round cells in different myocardial zones at different stages after myocardial infarction, showing a spatio-temporal and dynamic change. After myocardial infarction, the nanog expression in fibroblasts and small round cells in the infarcted zone (IZ) is much stronger than that in the margin zone (MZ) and remote infarcted zone (RIZ). From day 7 after myocardial infarction, the fibroblasts and small cells strongly expressed nanog protein in the IZ, and a few myocardial cells in the MZ and the RIZ and the numbers of nanog-positive fibroblasts and small cells reached the highest peak at 21 days after myocardial infarction, but in this period the number of nanog-positive myocardial cells decreased gradually. At 28 days after myocardial infarction, the numbers of all nanog-positive cells decreased into a low level. Therefore, our data suggest that all myocardial cells, fibroblasts and small round cells are involved in myocardial reconstruction after cardiac infarction. The nanog-positive myocardial cells may respond to early myocardial repair, and the nanog-positive fibroblasts and small round cells are the main source for myocardial reconstruction after cardiac infarction.

  17. Prognostic factors in patients hospitalized with acute heart failure syndrome

    Each year, there are over one million hospitalizations for acute heart failure syndrome (AHFS) in the United States alone,with a similar number in Western Europe. These patients have very high short-term (2-6 months) mortality and readmission rates, while the healthcare system incurs substantial costs. Until recently, the clinical characteristics, management patterns, and outcomes of these patients have been poorly understood and, in consequence, risk stratification for these patients has not been well defined. Several risk prediction models that can accurately identify high-risk patients have been developed in the last year using data from clinical trials, large registries or administrative databases. Use of multi-variable risk models at the time of hospital admission or discharge offers better risk stratification and should be encouraged, as it allows for appropriate allocation of existing resources and development of clinical trials testing new treatment strategies for patients admitted with AHFS. The emerging observation that the prognosis for the ensuing three to six months may be obtained at presentation for AHFS has major implications for development of future therapies.

    Acute myocardial infarction is a severe ischemic disease responsible for heart failure and sudden death. Here, we show that after acute myocardial infarction in mice, mature B lymphocytes selectively produce Ccl7 and induce Ly6Chi monocyte mobilization and recruitment to the heart, leading to enhanced tissue injury and deterioration of myocardial function. Genetic (Baff receptor deficiency) or antibody-mediated (CD20- or Baff-specific antibody) depletion of mature B lymphocytes impeded Ccl7 production and monocyte mobilization, limited myocardial injury and improved heart function. These effects were recapitulated in mice with B cell–selective Ccl7 deficiency. We also show that high circulating concentrations of CCL7 and BAFF in patients with acute myocardial infarction predict increased risk of death or recurrent myocardial infarction. This work identifies a crucial interaction between mature B lymphocytes and monocytes after acute myocardial ischemia and identifies new therapeutic targets for acute myocardial infarction.

    Levosimendan is a positive inotrope with vasodilating properties (inodilator) indicated for decompensated heart failure (HF) patients with low cardiac output. Accumulated evidence supports several pleiotropic effects of levosimendan beyond inotropy, the heart and decompensated HF. Those effects are not readily explained by cardiac function enhancement and seem to be related to additional properties of the drug such as anti-inflammatory, anti-oxidative and anti-apoptotic ones. Mechanistic and proof-of-concept studies are still required to clarify the underlying mechanisms involved, while properly designed clinical trials are warranted to translate preclinical or early-phase clinical data into more robust clinical evidence. The present position paper, derived by a panel of 35 experts in the field of cardiology, cardiac anesthesiology, intensive care medicine, cardiac physiology, and cardiovascular pharmacology from 22 European countries, compiles the existing evidence on the pleiotropic effects of levosimendan, identifies potential novel areas of clinical application and defines the corresponding gaps in evidence and the required research efforts to address those gaps.

    Poststreptococcal complications, such as acute rheumatic fever (ARF) and rheumatic heart disease (RHD), are common in resource-limited settings, with RHD recognised as the most common cause of paediatric heart disease worldwide. Managing these conditions in resource-limited settings can be challenging. We review the investigation and treatment options for ARF and RHD and, most importantly, prevention methods in an African setting.

    2002-01-01

    Full Text Available OBJECTIVE: To assess the association between cardiovascular risk factors and acute myocardial infarction as the first manifestation of ischemic heart disease, correlating them with coronary angiographic findings. METHODS: We carried out a cross-sectional study of 104 patients with previous acute myocardial infarction, who were divided into 2 groups according to the presence or absence of angina prior to acute myocardial infarction. We assessed the presence of angina preceding acute myocardial infarction and risk factors, such as age >55 years, male sex, smoking, systemic arterial hypertension, lipid profile, diabetes mellitus, obesity, sedentary lifestyle, and familial history of ischemic heart disease. On coronary angiography, the severity of coronary heart disease and presence of left ventricular hypertrophy were assessed. RESULTS: Of the 104 patients studied, 72.1% were males, 90.4% were white, 73.1% were older than 55 years, and 53.8% were hypertensive. Acute myocardial infarction was the first manifestation of ischemic heart disease in 49% of the patients. The associated risk factors were systemic arterial hypertension (RR=0.19; 95% CI=0.06-0.59; P=0.04 and left ventricular hypertrophy (RR=0.27; 95% CI=0,.8-0.88; P=0.03. The remaining risk factors were not statistically significant. CONCLUSION: Prevalence of acute myocardial infarction as the first manifestation of ischemic heart disease is high, approximately 50%. Hypertensive individuals more frequently have symptoms preceding acute myocardial infarction, probably due to ventricular hypertrophy associated with high blood pressure levels.

    Acute heart failure (AHF) is a clinical syndrome of different etiology and several clinical presentations. Cardiogenic shock patients have highest long-term mortality. In contrast to chronic heart failure, we have no evidence of therapeutic benefit for any treatment strategy from randomized clinical trials. Search for new pharmacologic and non-pharmacologic therapies is ongoing. Both causal and symptomatic treatment of AHF episode should be initiated as soon as possible. This review is focused on trends in acute heart failure therapy at the beginning of 21st century.

    2008-04-01

    Acute resistance exercise (RE) has been shown to reduce cardiac vagal control. Whether this would in turn affect QTc interval (an index of ventricular depolarization/repolarization) or heart rate complexity is not known. Heart rate variability (HRV), heart rate complexity (SampEn), and QT interval (rate corrected using Bazett, Fridericia, Hodges, and Framingham) were measured before and 5 min after an acute RE bout in twelve healthy young men. Normalized high frequency power of HRV (an index of cardiac parasympathetic modulation; HF (nu)), and SampEn were reduced following RE (p heart rate complexity and increased QTc length. Thus, during recovery from acute RE, there is prolongation of depolarization and repolarization of the ventricles concomitant with reduced cardiac irregularity, and this may be related to a reduction in cardiac vagal control.

    In patients with propionic aciduria, the accumulating metabolite propionyl-CoA causes a disturbance of the urea cycle via the inhibition of N-acetylglutamate synthesis. Lack of this allosteric activator results in an inhibition of carbamoylphosphate synthase (CPS). This finally leads to hyperammonaemia. In two patients with decompensated propionic aciduria the CPS activator carbamylglutamate was tested for its ability to antagonize the propionyl-CoA associated hyperammonaemia. Oral carbamyl glutamate administration resulted in a significant increase in ammonia detoxification and could avoid further dialysis therapy. Safe, fast and easy to administer, carbamyl glutamate improves the acute therapy of decompensated propionic aciduria by increasing ammonia detoxification and avoiding hyperammonaemia.

    In patients with methylmalonic aciduria (MMA), the accumulating metabolite propiony-CoA results in an inhibition of the urea circle via the decreased synthesis of N-acetylglutamate, an essential activator of carbamylphosphat synthetase (CPS). This results in one of the major clinical problems which is hyperammonaemia. In a patient with decompensated MMA, the CPS activator carbamylglutamate was tested for its ability to antagonize the propionyl-CoA-induced hyperammonaemia. Oral carbamylgutamate administration resulted in an impressive increase in ammonia detoxification compared to peritoneal dialysis. Safe, fast and easy to administer, carbamylglutamate improves the acute therapy of decompensated MMA by increasing ammonia detoxification and avoiding hyperammonaemia.

    Full Text Available Rheumatic heart disease remains the most important cause of acquired heart disease in children and young adults. Different kinds of rhythm and conduction disturbances may be seen during the course of acute rheumatic fever (ARF. Long PR intervals are found commonly in rheumatic fever, but complete atrioventricular (AV block is an exceptionally rare manifestation. This case report is about a 14 year-old-female patient diagnosed as ARF based on migratory arthralgia and mild carditis who also developed complete heart block on admission. Electrocardiogram on the 3rd day of hospitalization depicts 2nd degree atrioventricular block (Mobitz I combined with PR prolongation. The ECG revealed a normal sinus rhythm with PR prolongation on the 4th day of hospitalization. Rarely, complete AV heart block can occur as a complication of ARF and may develop during the acute phase

    Systemic lupus erythematosus is an autoimmune disease with diffuse organ involvement. The cardiac complications include pericarditis, myocarditis, pulmonary hypertension, coronary vasculitis, and Libman-Sacks endocarditis. Symptomatic lupus myocarditis presenting with left ventricular dysfunction, acute heart failure, and pulmonary edema, although rare, is a life-threatening complication. We report the occurrence of acute lupus myocarditis in a 38-year-old postpartum female who had a cesarean section a week before presentation for preeclampsia. Initially she was managed for pneumonia but later found to have acute pericarditis and myocarditis related to systemic lupus erythematosus. She had a complicated hospital course including acute respiratory failure and cardiogenic shock. She was started on pulse dose steroids besides the treatment for heart failure and had a dramatic improvement within days.

    Full Text Available Abstract Pheochromocytomas are catecholamine producing tumors arising mostly from chromaffin cells of the adrenal medulla. The most common clinical presentation is hypertension, mainly in the form of paroxymal episodes. Cardiovascular manifestations include malignant arrhythmia and catecholamine cardiomyopathy, mimicking acute coronary syndromes and acute heart failure. There are reports of pheochromocytomas presenting as acute coronary syndrome and rapidly leading to cardiogenic shock; the failure of intensive medical treatment in these cases has prompted the need for emergency adrenalectomy as the only remaining option. We report on a case of complicated pheochromocytoma presenting as cardiogenic shock, in which emergency adrenalectomy was performed following a total lack of response to intensive medical treatment.

    Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease. In acute heart failure, and especially in cardiogenic shock related to ischemic conditions, vasopressors and inotropes are used. However, both pathophysiological considerations and available clinical data suggest that these treatments may have disadvantageous effects. The inodilator levosimendan offers potential benefits due to a range of distinct effects including positive inotropy, restoration of ventriculo-arterial coupling, increases in tissue perfusion, and anti-stunning and anti-inflammatory effects. In clinical trials levosimendan improves symptoms, cardiac function, hemodynamics, and end-organ function. Adverse effects are generally less common than with other inotropic and vasoactive therapies, with the notable exception of hypotension. The decision to use levosimendan, in terms of timing and dosing, is influenced by the presence of pulmonary congestion, and blood pressure measurements. Levosimendan should be preferred over adrenergic inotropes as a first line therapy for all ACS-AHF patients who are under beta-blockade and/or when urinary output is insufficient after diuretics. Levosimendan can be used alone or in combination with other inotropic or vasopressor agents, but requires monitoring due to the risk of hypotension.

    The effect of decaffeinated coffee on the cardiovascular exercise performance in nine healthy volunteers was evaluated in a double-blind randomized fashion. The heart rate, blood pressure, and duration of exercise were unchanged, and no arrhythmias or ischemic changes were seen on the electrocardiogram after drinking decaffeinated coffee. It was concluded that decaffeinated coffee has no discernible, acute, adverse cardiovascular effects. PMID:3339645

    Full Text Available This study aimed to determine if there are differences in inflammatory markers in the acute phase between systolic heart failure and heart failure with preserved systolic function. One hundred and thirty-one patients with acute heart failure were recruited consecutively. At admission, plasma fibrinogen, Creactive protein, sialic acid, von Willebrand factor, vascular endothelial growth factor, interleukin-6 and NTproBNP were all evaluated. If the ejection fraction was 45% or over patients were included in the HF-PSF group; the remaining patients were included in the SHF group. The HF-PSF patients were older (72±10 vs 63±12 years, P<0.001, presented a higher rate of atrial fibrillation (56.1 vs 21.3%, P<0.001, and had a lower rate of hemoglobin (12.2±2 vs 13.3±2.1 g/dL, P<0.01. No significant differences were observed in the inflammation markers analyzed among SHF and HFPSF groups. In the acute phase of heart failure there is a marked elevation of inflammatory markers but there are no differences in the inflammatory markers analyzed between the two different types of heart failure

    Decompensated heart failure, either acute (cardiogenic shock) or chronic (terminal heart failure) may become refractory to conventional therapy, then requiring mechanical assistance of the failing heart to improve hemodynamics. In the acute setting, aortic balloon counterpulsation is used as first line therapy. In case of failure, other techniques include the extracorporal membrane oxygenator or a percutaneous left ventricular assist device, such as the TandemHeart or the Impella. In chronic heart failure, long-term left ventricular assist devices can be surgically implanted. The continuous flow devices give here the best results. The aim of the present review article is to present with some details the various methods of mechanical left ventricle assistance to which the intensivist may be confronted in his daily practice.

Contributing factors for pulmonary oedema include, administration of tocolytics, underlying cardiac disease, iatrogenic fluid overload and preeclampsia acounting 0.08% of pregnancies. Pulmonary embolism, amniotic fluid embolism, pneumonia, aspiration and pulmonary oedema are some of the potentially devastating conditions that should be considered by the attending physician.

  10. Myocardial creatine levels do not influence response to acute oxidative stress in isolated perfused heart.

    Full Text Available Multiple studies suggest creatine mediates anti-oxidant activity in addition to its established role in cellular energy metabolism. The functional significance for the heart has yet to be established, but antioxidant activity could contribute to the cardioprotective effect of creatine in ischaemia/reperfusion injury.To determine whether intracellular creatine levels influence responses to acute reactive oxygen species (ROS exposure in the intact beating heart. We hypothesised that mice with elevated creatine due to over-expression of the creatine transporter (CrT-OE would be relatively protected, while mice with creatine-deficiency (GAMT KO would fare worse.CrT-OE mice were pre-selected for creatine levels 20-100% above wild-type using in vivo (1H-MRS. Hearts were perfused in isovolumic Langendorff mode and cardiac function monitored throughout. After 20 min equilibration, hearts were perfused with either H2O2 0.5 µM (30 min, or the anti-neoplastic drug doxorubicin 15 µM (100 min. Protein carbonylation, creatine kinase isoenzyme activities and phospho-PKCδ expression were quantified in perfused hearts as markers of oxidative damage and apoptotic signalling. Wild-type hearts responded to ROS challenge with a profound decline in contractile function that was ameliorated by co-administration of catalase or dexrazoxane as positive controls. In contrast, the functional deterioration in CrT-OE and GAMT KO hearts was indistinguishable from wild-type controls, as was the extent of oxidative damage and apoptosis. Exogenous creatine supplementation also failed to protect hearts from doxorubicin-induced dysfunction.Intracellular creatine levels do not influence the response to acute ROS challenge in the intact beating heart, arguing against creatine exerting (patho-physiologically relevant anti-oxidant activity.

    Cardiovascular disease is the leading cause of mortality in American women. Since 1984, the annual cardiovascular disease mortality rate has remained greater for women than men; however, over the last decade, there have been marked reductions in cardiovascular disease mortality in women. The dramatic decline in mortality rates for women is attributed partly to an increase in awareness, a greater focus on women and cardiovascular disease risk, and the increased application of evidence-based treatments for established coronary heart disease. This is the first scientific statement from the American Heart Association on acute myocardial infarction in women. Sex-specific differences exist in the presentation, pathophysiological mechanisms, and outcomes in patients with acute myocardial infarction. This statement provides a comprehensive review of the current evidence of the clinical presentation, pathophysiology, treatment, and outcomes of women with acute myocardial infarction.

    Acute dyspnea with pulmonary oedema in postpartum is uncommon but life-threatening event. Contributing factors for pulmonary oedema include, administration of tocolytics, underlying cardiac disease, iatrogenic fluid overload and preeclampsia acounting 0.08% of pregnancies. Pulmonary embolism, amniotic fluid embolism, pneumonia, aspiration and pulmonary oedema are some of the potentially devastating conditions that should be considered by the attending physician. Here, we report a case of postpartum acute pulmonary oedema referred to causality after an emergency caesarean section in a private hospital. No matter what the underlying pathology, prompt administration and appropriate resuscitation is always the first priority. Only after the patient has been stabilized attention must be turned to diagnosis and specific treatment. A diagnosis of severe Mitral Stenosis, probably of rheumatic origin was made after stabilizing the patient.

  13. The Mitochondrial Calcium Uniporter Selectively Matches Metabolic Output to Acute Contractile Stress in the Heart

    Full Text Available In the heart, augmented Ca2+ fluxing drives contractility and ATP generation through mitochondrial Ca2+ loading. Pathologic mitochondrial Ca2+ overload with ischemic injury triggers mitochondrial permeability transition pore (MPTP opening and cardiomyocyte death. Mitochondrial Ca2+ uptake is primarily mediated by the mitochondrial Ca2+ uniporter (MCU. Here, we generated mice with adult and cardiomyocyte-specific deletion of Mcu, which produced mitochondria refractory to acute Ca2+ uptake, with impaired ATP production, and inhibited MPTP opening upon acute Ca2+ challenge. Mice lacking Mcu in the adult heart were also protected from acute ischemia-reperfusion injury. However, resting/basal mitochondrial Ca2+ levels were normal in hearts of Mcu-deleted mice, and mitochondria lacking MCU eventually loaded with Ca2+ after stress stimulation. Indeed, Mcu-deleted mice were unable to immediately sprint on a treadmill unless warmed up for 30 min. Hence, MCU is a dedicated regulator of short-term mitochondrial Ca2+ loading underlying a “fight-or-flight” response that acutely matches cardiac workload with ATP production.

    pacientes internados por descompensación de la insuficiencia cardiaca y con empleo por más de 15 días de dobutamina, o una o más intentos sin éxito de retirada; dosis optimizada de IECA; y FEVI BACKGROUND: During heart failure (HF decompensation, an intense activation of the renin-angiotensin-aldosterone system occurs; however, the use of angiotensin-converting enzyme inhibitor (ACEI cannot block it completely. Otherwise, the addition of angiotensin II receptor blocker (ARB can be useful when the inotropic dependence occurs. We evaluated the efficacy of the ARB-ACEI association on dobutamine withdrawal in advanced decompensated HF. OBJECTIVE: To assess the efficacy of association angiotensin receptor blocker - angiotensin converting enzyme inhibitor to withdraw the intravenous inotropic support in decompensated severe heart failure. METHODS: In a case-control study (N = 24, we selected patients admitted at the hospital due to HF that had been using dobutamine for more than 15 days, with one or more unsuccessful drug withdrawal attempts; optimized dose of ACEI and ejection fraction (EF < 0.45. Then, the patients additionally received ARB (n=12 or not (control, n=12. The outcome was the successful dobutamine withdrawal, evaluated by logistic regression, with a p < 0.05. RESULTS: The EF was 0.25 and the age was 53 years, with a dobutamine dose of 10.7 μg/kg.min. The successful drug withdrawal was observed in 8 patients from the ARB group (67.7% and in 2 patients from the control group (16.7%. The odds ratio (OR was 10.0 (95%CI: 1.4 to 69.3; p = 0.02. The worsening in renal function was similar (ARB group: 42% vs. control group: 67%; p=0.129. CONCLUSION: In this pilot study, the ARB-ACEI association was associated with successful dobutamine withdrawal in advanced decompensated heart failure. The worsening in renal function was similar in both groups. Further studies are necessary to clarify the issue.

    Most patients with heart failure (HF) respond within a matter of hours to days to available medical treatments. Nursing's current challenge in HF inpatient care is their short length of stay and content dense patient education needs. Only 54% of US hospitalized HF patients received all HF-1 mandated discharge education components. By using nursing evidence and adult learning principles, we can transform HF-1 topic descriptions into a "workable" plan for our newly stable HF patients. Pragmatically viewed, we need to turn the 5 key areas upside down to meet our HF patient's needs during early hospitalization: (1) recognizing symptoms, (2) pacing rest and exercise, (3) daily weights, (4) restricting sodium and fluids, and (5) managing medications. This "organizing" issue is important to our success and costly to all those who accepted the published order as prescriptive for their video, audio, and printed discharge education materials.

    Objective:To through counting serum high-sensitivity C-reactive protein (hs-CRP), prealbumin (PAB) and the ratio of the two to analyze its predictive value on acute myocardial infarction complicated with postoperative acute heart failure.Methods: 100 cases of acute myocardial infarction patients treated in our hospital from January 2013 to January 2015 were selected as research objects. Serum PAB and hs-CRP values on the next day of admission as well as after PCI surgery were recorded respectively. Then PAB data change before and after surgery, PAB and hs-CRP change with or without postoperative cardiovascular events (heart failure) as well as the value of the ratio of hs-CRP and PAB on prediction of acute myocardial infarction complicated with acute heart failure was compared.Results:Postoperative PAB in 100 cases of myocardial infarction patients increased from (0.19±0.05) to (0.24±0.06), and the differences had statistical significance; 40 cases had postoperative cardiovascular events (heart failure), incidence being 40%; PAB in patients without postoperative cardiovascular events (heart failure) increased significantly, hs-CRP decreased significantly, and the differences had statistical significance; Logistic regression univariate analysis showed that acute myocardial infarction complicated with heart failure was associated with diabetes, PAB, hs-CRP and In (hs-CRP/PAB), and multivariate analysis showed that it was associated with In (hs-CRP/PAB). Conclusion:hs-CRP in patients with acute myocardial infarction increases, PAB decreases, postoperative PAB increases relatively, hs-CRP and PAB data shows different degrees of change with or without postoperative cardiovascular (heart failure), and In (hs-CRP/PAB) is associated with acute myocardial infarction complicated with heart failure and can be used as its prediction index.

    Haemodynamic changes after intravenous administration of 0.4 mg beta-methyldigoxin or 0.4 mg digoxin daily were measured on the first to fourth day in 42 patients in heart failure after onset of transmural myocardial infarction. Regular reduction in filling pressure and increased stroke volume while arterial blood pressure remained unaltered pointed to improved contractility. Digitalization in the first few days after infarction achieved sustained tendency towards improved haemodynamics. It is concluded that early digitalization is indicated in patients with acute myocardial infarction if there are signs of heart failure.

    Full Text Available Pheochromocytoma is a rare neuroendocrine tumor with a highly variable clinical presentation. The serious and potentially lethal cardiovascular complications of these tumors are related to the effects of secreted catecholamines. We describe a case of a 50-year-old woman urgently admitted to our hospital because of symptoms and clinical and instrumental findings consistent with an acute coronary syndrome complicated by acute heart failure. Urgent coronary angiography showed normal coronary arteries. During her hospital stay, the recurrence of episodes characterized by a sudden increase in blood pressure, cold sweating, and nausea allowed us to hypothesize a pheochromocytoma. The diagnosis was confirmed by elevated levels of urinary catecholamines and by the finding of a left adrenal mass on magnetic resonance imaging. The patient underwent left adrenalectomy. Therefore, the initial diagnosis was critically reappraised and reviewed as a cardiac manifestation of a pheochromocytoma during catecholaminergic crisis.

    Full Text Available Complement-mediated hemolytic uremic syndrome (otherwise known as atypical HUS is a rare disorder of uncontrolled complement activation that may be associated with heart failure. We report the case of a 49-year-old female with no history of heart disease who presented with microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Given her normal ADAMSTS13 activity, evidence of increased complement activation, and renal biopsy showing evidence of thrombotic microangiopathy, she was diagnosed with complement-mediated HUS. She subsequently developed acute hypoxemic respiratory failure secondary to pulmonary edema requiring intubation and mechanical ventilation. A transthoracic echocardiogram showed evidence of a Takotsubo cardiomyopathy with an estimated left ventricular ejection fraction of 20%, though ischemic cardiomyopathy could not be ruled out. Treatment was initiated with eculizumab. After several failed attempts at extubation, she eventually underwent tracheotomy. She also required hemodialysis to improve her uremia and hypervolemia. After seven weeks of hospitalization and five doses of eculizumab, her renal function and respiratory status improved, and she was discharged in stable condition on room air and independent of hemodialysis. Our case illustrates a rare association between acute systolic heart failure and complement-mediated HUS and highlights the potential of eculizumab in stabilizing even the most critically-ill patients with complement-mediated disease.

    The autonomic nervous system and the inflammatory response are intimately linked. Heart rate variability (HRV) analysis is a widely used method to assess cardiac autonomic nervous system activity, and changes in HRV indices may correlate with inflammatory markers. Here, we investigated whether baseline HRV predicts the acute inflammatory response to endotoxin. Second, we investigated whether the magnitude of the inflammatory response correlated with HRV alterations. Forty healthy volunteers received a single intravenous bolus of 2 ng/kg endotoxin (LPS, derived from Escherichia coli O:113). Of these, 12 healthy volunteers were administered LPS again 2 weeks later. Heart rate variability was determined at baseline (just before LPS administration) and hourly thereafter until 8 h after LPS administration. Plasma cytokine levels were determined at various time points. Baseline HRV indices did not correlate with the magnitude of the LPS-induced inflammatory response. Despite large alterations in HRV after LPS administration, the extent of the inflammatory response did not correlate with the magnitude of HRV changes. In subjects who were administered LPS twice, inflammatory cytokines were markedly attenuated after the second LPS administration, whereas LPS-induced HRV alterations were similar. Heart rate variability indices do not predict the acute inflammatory response in a standardized model of systemic inflammation. Although the acute inflammatory response results in HRV changes, no correlations with inflammatory cytokines were observed. Therefore, the magnitude of endotoxemia-related HRV changes does not reflect the extent of the inflammatory response.

However, optimal management of free floating right heart thrombus remains controversial with no clear consensus. We present the case of a 74-year-old woman who presented to the emergency department with acute onset dyspnea on minimal exertion which had developed over a period of 1 day. A computed tomography of the chest demonstrated massive bilateral proximal pulmonary embolism. A bedside transthoracic echocardiography performed showed a moderately dilated, poorly functioning right ventricle with visible highly mobile serpiginous thrombus moving to and fro across the tricuspid valve. Thrombolytic therapy was immediately initiated with tenecteplase which resulted in excellent results. Although there is no clear consensus for the management of right heart thrombus associated with pulmonary embolism, thrombolysis is readily available and can be effective in carefully selected patients.

    The phosphodiesterase inhibitor enoximone has both vasodilating and positive inotropic pharmacological properties. The balance between vasodilation and positive inotropism may be different between the various types of heart failure as well as the various stages of heart failure. Therefore, we investigated the effect of intravenous application of enoximone (1 mg/kg body weight) in a cohort of patients (n = 10) suffering from acute or subacute heart failure mainly due to ischemia or hypoxia. All patients had high left ventricular filling pressure, low cardiac output and were pretreated with intravenous dobutamine. Enoximone increased cardiac output from 3.2 +/- 1.2 to 5.5 +/- 2.2 l/min, increased heart rate from 94 +/- 20 to 100 +/- 18 beats/min, decreased systemic peripheral resistance from 1770 +/- 861 to 931 +/- 340 dyn.sec.cm-5 and decreased pulmonary wedge pressure from 24 +/- 5 to 20 +/- 6 mmHg, significantly. However, systolic aortic pressure, systolic pulmonary pressure and right atrial pressure were not significantly altered. We conclude that in a selected group of patients enoximone-given intravenously and acutely in the intensive care unity-can induce beneficial effects on central hemodynamics without critical falls in perfusion pressure.

    Full Text Available Acute pulmonary thromboembolism (PTE is a life threatening condition which requires early diagnosis and management. Electrocardiogram (ECG is helpful for suspecting the disease. The various ECG changes are sinus tachycardia, P pulmonale, Right bundle branch block (RBBB -incomplete or complete, axis shift, S1Q3T3, T wave inversion, and ST-segment depression in leads V1-4, aVF, and Lead III, supra ventricular tachycardia, low voltage QRS complex in limb leads. In addition, sinus bradycardia and complete heart block (CHB can be seen. CHB has been reported as an exceptionally rare manifestation of acute PTE. Here, we are reporting a case of 66 year old male presented with CHB with acute pulmonary thromboembolism, who reverted to sinus rhythm after thrombolysis.

    Diabetes impairs copper (Cu) regulation, causing elevated serum Cu and urinary Cu excretion in patients with established cardiovascular disease; it also causes cardiomyopathy and chronic cardiac impairment linked to defective Cu homeostasis in rats. However, the mechanisms that link impaired Cu regulation to cardiac dysfunction in diabetes are incompletely understood. Chronic treatment with triethylenetetramine (TETA), a Cu²⁺-selective chelator, improves cardiac function in diabetic patients, and in rats with heart disease; the latter displayed ∼3-fold elevations in free Cu²⁺ in the coronary effluent when TETA was infused into their coronary arteries. To further study the nature of defective cardiac Cu regulation in diabetes, we employed an isolated-perfused, working-heart model in which we infused micromolar doses of Cu²⁺ into the coronary arteries and measured acute effects on cardiac function in diabetic and non-diabetic-control rats. Infusion of CuCl₂ solutions caused acute dose-dependent cardiac dysfunction in normal hearts. Several measures of baseline cardiac function were impaired in diabetic hearts, and these defects were exacerbated by low-micromolar Cu²⁺ infusion. The response to infused Cu²⁺ was augmented in diabetic hearts, which became defective at lower infusion levels and underwent complete pump failure (cardiac output = 0 ml/min) more often (P hearts. To our knowledge, this is the first report describing the acute effects on cardiac function of pathophysiological elevations in coronary Cu²⁺. The effects of Cu²⁺ infusion occur within minutes in both control and diabetic hearts, which suggests that they are not due to remodelling. Heightened sensitivity to the acute effects of small elevations in Cu²⁺ could contribute substantively to impaired cardiac function in patients with diabetes and is thus identified as a new mechanism of heart disease.

    2014-03-01

    Diagnosis of acute heart failure (HF) is difficult in elderly patients with multiple comorbidities. Risk scales and classification criteria based exclusively on clinical manifestations, such as the Framingham scales, lack sufficient specificity. In addition to clinical manifestations, diagnosis should be based on two key factors: natriuretic peptides and echocardiographic study. When there is clinical suspicion of acute HF, a normal natriuretic peptide level will rule out this process. When a consistent clinical suspicion is present, an echocardiographic study should also be performed. Diagnosis of HF with preserved ejection fraction (HF/pEF) requires detection of an enlarged left atrium or the presence of parameters of diastolic dysfunction. Elevation of cardiac biomarkers seems to be due to myocardial injury and the compensatory mechanisms of the body against this injury (hormone and inflammatory response and repair mechanisms). Elevation of markers of cardiac damage (troponins and natriuretic peptides) have been shown to be useful both in the diagnosis of acute HF and in prediction of outcome. MMP-2 could be useful in the diagnosis of HF/pEF. In addition to biomarkers with diagnostic value, other biomarkers are helpful in prognosis in the acute phase of HF, such as biomarkers of renal failure (eGFR, cystatin and urea), inflammation (cytokines and CRP), and the cell regeneration marker, galectin-3. A promising idea that is under investigation is the use of panels of biomarkers, which could allow more accurate diagnosis and prognosis of acute HF.

Phase-rectified signal averaging is a newly developed technique for assessing cardiac autonomic function, by detecting sympathetic and vagal nerve activity separately through calculating acceleration capacity (AC and deceleration capacity (DC of heart rate. In this study, we used this technique for the first time to investigate the cardiac autonomic function of patients with acute hemispheric ischemic stroke. Methods: A 24-hour Holter monitoring was performed in 63 patients with first-ever acute ischemic stroke in hemisphere and sinus rhythm, as well as in 50 controls with high risk of stroke. DC, AC, heart rate variability parameters, standard deviation of all normal-to-normal intervals (SDNN, and square root of the mean of the sum of the squares of differences between adjacent normal-to-normal intervals (RMSSD were calculated. The National Institutes of Health Stroke Scale (NIHSS was used to assess the severity of stroke. We analyzed the changes of DC, AC, SDNN, and RMSSD and also studied the correlations between these parameters and NIHSS scores. Results: The R–R (R wave to R wave on electrocardiogram intervals, DC, AC, and SDNN in the cerebral infarction group were lower than those in controls (P=0.003, P=0.002, P=0.006, and P=0.043, but the difference of RMSSD and the D-value and ratio between absolute value of AC (|AC| and DC were not statistically significant compared with those in controls. The DC of the infarction group was significantly correlated with |AC|, SDNN, and RMSSD (r=0.857, r=0.619, and r=0.358; P=0.000, P=0.000, and P=0.004.

    Acute heart failure is a fatal syndrome. Emergency physicians, cardiologists, intensivists, nurses and other health care providers have to cooperate to provide optimal benefit. However, many treatment decisions are opinion-based and few are evidenced-based. This consensus paper provides guidance to practicing physicians and nurses to manage acute heart failure in the pre-hospital and hospital setting. Criteria of hospitalization and of discharge are described. Gaps in knowledge and perspectives in the management of acute heart failure are also detailed. This consensus paper on acute heart failure might help enable contiguous practice.

    Objective To explore the correlation between hypoglycemia and the increased mortality of patients with acute decompensated liver cirrhosis.Methods A retrospective study was conducted on the clinical data of 120 patients with acute decompensated liver cirrhosis admitted to the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University from December 2011 to December 2014. The patients were divided into three groups: hypoglycemia group (glucose 10.0 mmol/L, 15 cases). The differences in hepatic carcinoma, decompensation symptoms, the incidence of known glycometabolic disorder, hospitalization situation, indicators of liver function and indexes of blood gas analysis were compared among three groups. The patients' age, hepatic carcinoma, ascites, hepatorenal syndrome, encephalopathy, bleeding, jaundice and glycometabolic disorder, etc were analyzed by the univariate analysis. The resulting risk factors with statistically significant differences were analyzed by multivariate logistic regression method in order to screen out the risk factors of increased mortality.Results The incidences of hepatorenal syndrome [42.9% (9/21) vs. 22.6% (19/84), 33.3% (5/15)] and jaundice [38.1% (7/21) vs. 20.2% (17/84), 13.3% (2/15)], rate of admission into intensive care unit (ICU) [14.3% (3/21) vs. 10.7% (9/84), 13.3% (2/15)] and in-hospital mortality [23.8% (5/21) vs. 10.7% (9/84), 20.0% (3/15)] in the hypoglycemia group were significantly higher than those in the normoglycemia group and hyperglycemia group (P 0.05). Univariate analysis showed that advanced age, hepatic carcinoma, hepatorenal syndrome, bleeding, jaundice and glycometabolic disorder hypoglycemia were the risk factors of the death in patients with acute decompensated liver cirrhosis (P 10.1 mmol/L,15例),比较3组患者肝癌、代偿失调症状、已知糖代谢紊乱发生率及住院情况、肝功能指标和血气分析指标的差异,对患者的年龄、肝癌、腹水、肝肾综合

    Described are certain clinical and morphologic features of one patient with acute, another with subacute, and one with chronic cor pulmonale. All 3 had evidence of severe pulmonary hypertension. The patient with acute cor pulmonale 4 days after coronary bypass for unstable angina pectoris suddenly developed severe breathlessness with cyanosis and had fatal cardiac arrest and necropsy disclosed massive pulmonary embolism. The patient with subacute cor pulmonale had severe right-sided heart failure for 5 weeks and necropsy disclosed microscopic-sized neoplastic pulmonary emboli from a gastric carcinoma without parenchymal pulmonary metastases. The patient with chronic cor pulmonale had evidence of right-sided heart failure for years, the result of primary or idiopathic pulmonary hypertension almost certainly present from birth because the pattern of elastic fibers in the pulmonary trunk was that seen in newborns where the pressure in the pulmonary trunk and ascending aorta are similar. The patient with chronic cor pulmonale had plexiform pulmonary lesions indicative of irreversible pulmonary hypertension. Neither the acute nor the subacute patient had chronic pulmonary vascular changes. All 3 patients had dilated right ventricular cavities and non-dilated left ventricular cavities and only the patient with chronic cor pulmonale had right ventricular hypertrophy.

    A 50-year-old man with no previous history of cardiovascular disease or risk factors was admitted for syncope and orthopnea. Importantly, he underwent recent chemotherapy with 5-fluorouracil (5-FU) until 1 day before his acute presentation. In the emergency room, patient developed asystole and was successfully resuscitated for 2 min. At coronary angiography, no signs of coronary artery disease were detectable, but transthoracic echocardiography showed a severely decreased left-ventricular systolic function. Due to the progressive cardiogenic shock, an extracorporeal membrane oxygenation (ECMO) support was used as bridge-to-recovery and to avoid the use of sympathomimetics with their known disadvantages. On ECMO support, hemodynamic stabilization was evident and medical heart failure treatment was commenced. Left-ventricular function recovered to normal values within a short period of time. Cardiac complications after chemotherapy with 5-FU are not rare and should be taken into consideration even in acute heart failure with cardiogenic shock. ECMO as the most potent form of acute cardiorespiratory support enables complete relief of cardiac workload and therefore recovery of cardiac function.

    Full Text Available The aim of this study was to evaluate the potential positive effect of black grape juice (BGJ on lipid peroxidation considering Total Body Irradiation (TBI in Wistar rats. As a potential feasible means of evaluation in situ, blood serum lactate dehydrogenase (LDH levels were evaluated as a marker for heart damage from acute radiation syndrome (ARS. Twenty rats were divided into four groups, two of them being irradiated by gamma-rays from a Co-60 source. Animals were treated by gavage with 2 mL per day of BGJ or placebo for one week before and 4 days after 6 Gy whole body gamma-irradiation, when they were euthanasiated. LDH on serum and lipid peroxidation on heart tissue were evaluated. High concentration of metabolites from lipid peroxidation in heart, and high LDH level on serum were found only in gamma-irradiated group given placebo, mainly at the first 24 h after radiation. Phytochemical analysis of BGJ was performed by determining total phenolics, flavonoids, and tannins followed by a high-performance liquid chromatography (HPLC/DAD analysis, which showed resveratrol as the major constituent. Results suggest that BGJ is a good protective candidate compound against heart damage from ARS and its effects suggest its use as a radiomodifier.

    2015-04-01

    Heart failure with preserved ejection fraction (HFpEF) constitutes ~50% of all heart failure diagnoses and is associated with considerable morbidity and mortality. The treatment of HFpEF can be challenging due to a lack of evidence supporting the benefit of various drug therapies. In practice, treatment can be divided into acute and chronic management. Acute therapy for decompensated heart failure is similar for both HFpEF and heart failure with reduced ejection fraction. The mainstay of treatment is diuretics to reduce volume overload and improve dyspnea. Patients with an acute exacerbation of HFpEF and rapid atrial fibrillation (AF) should be rate controlled with negative chronotropic agents. For chronic therapy, patients with HFpEF should not be treated like patients with heart failure with reduced ejection fraction. Chronic management of HFpEF can be simplified by using three strategies based on applicability: treat precipitating conditions (e.g., hypertension, AF), control symptoms by maintaining euvolemia with diuretics, and avoid therapies that have been shown not to be beneficial unless another compelling indication exists. Nondrug interventions for HFpEF include salt and fluid restriction, regular physical activity, and referral to a heart function clinic, if appropriate.

    Acute heart failure (AHF) is a multi-organ dysfunction syndrome. In addition to known cardiac dysfunction, non-cardiac comorbidity, frailty and disability are independent risk factors of mortality, morbidity, cognitive and functional decline, and risk of institutionalization. Frailty, a treatable and potential reversible syndrome very common in older patients with AHF, increases the risk of disability and other adverse health outcomes. This position paper highlights the need to identify frailty in order to improve prognosis, the risk-benefits of invasive diagnostic and therapeutic procedures, and the definition of older-person-centered and integrated care plans.

    Background Acute allograft rejection in heart transplantation remains as one of the major complications. Obligatory graft surveillance is still achieved with the invasive and expensive endomyocardial biopsy (EMB). Our study aimed to study the use of intramyocardial electrograms combined with other noninvasive methods for the monitoring of acute rejection after human heart transplantation. Methods Permanent pacemakers were implanted in 58 patients undergoing heart transplantations. Intramyocardial electrograms (IMEG) were recorded periodically and the results were compared with those from EMBs. The R wave amplitude of the IMEG was used as the index value, the average R wave amplitude at the third week following transplantation was considered as the baseline, and a reduction of >20% compared with the baseline was regarded as a positive result. EMB was performed in cases of positive IMEG results and also at other times. Other noninvasive methods were used to help the diagnosis. Acute rejection (AR) was defined as international Society of Heart-Lung Transplantation grade Ilia or higher.Results We obtained 1231 IMEG records and 127 EMBs. Of the total 127 EMBs, 53 were positive, in which there were 42 IMEG positive results and 11 negative, while in the rest 74 negative EMBs, there were 9 IMEG positive results and 65 negative. The sensitivity of IMEG for the diagnosis of AR was 79.2%, and the specificity was 87.8%. The positive predictive value was 82.4% and the negative predictive value was 85.5%. Of the total of 1231 IMEG records, 51 were positive and 1180 were negative. Excluding 11 proved by EMB to be false negative, if the other 1169 were considered as no evidence of rejection, through the other noninvasive methods, AR diagnosed by this noninvasive monitoring strategy, the sensitivity was 79.2%, and the specificity was 99.2%. The positive predictive value was 82.4% and the negative predictive value was 99.1%. Conclusions IMEG can be used as a noninvasive method for

    Treatment of acute cardiac ischemia remains an area in which there are opportunities for therapeutic improvement. Despite significant advances, many patients still progress to cardiac hypertrophy and heart failure. Timely reperfusion is critical in rescuing vulnerable ischemic tissue and is directly related to patient outcome, but reperfusion of the ischemic myocardium also contributes to damage. Overproduction of reactive oxygen species, initiation of an inflammatory response and deregulation of calcium homeostasis all contribute to injury, and difficulties in delivering a sufficient quantity of drug to the affected tissue in a controlled manner is a limitation of current therapies. Nanotechnology may offer significant improvements in this respect. Here, we review recent examples of how nanoparticles can be used to improve delivery to the ischemic myocardium, and suggest some approaches that may lead to improved therapies for acute cardiac ischemia.

    In vitro studies suggested that glucose metabolism through the oxidative pentose phosphate pathway (oxPPP) can paradoxically feed superoxide-generating enzymes in failing hearts. We therefore tested the hypothesis that acute inhibition of the oxPPP reduces oxidative stress and enhances function and metabolism of the failing heart, in vivo. In 10 chronically instrumented dogs, congestive heart failure (HF) was induced by high-frequency cardiac pacing. Myocardial glucose consumption was enhanced by raising arterial glycemia to levels mimicking postprandial peaks, before and after intravenous administration of the oxPPP inhibitor 6-aminonicotinamide (80 mg/kg). Myocardial energy substrate metabolism was measured with radiolabeled glucose and oleic acid, and cardiac 8-isoprostane output was used as an index of oxidative stress. A group of five chronically instrumented, normal dogs served as control. In HF, raising glycemic levels from ∼ 80 to ∼ 170 mg/dL increased cardiac isoprostane output by approximately twofold, whereas oxPPP inhibition normalized oxidative stress and enhanced cardiac oxygen consumption, glucose oxidation, and stroke work. In normal hearts glucose infusion did not induce significant changes in cardiac oxidative stress. Myocardial tissue concentration of 6P-gluconate, an intermediate metabolite of the oxPPP, was significantly reduced by ∼ 50% in treated versus nontreated failing hearts, supporting the inhibitory effect of 6-aminonicotinamide. Our study indicates an important contribution of the oxPPP activity to cardiac oxidative stress in HF, which is particularly pronounced during common physiological changes such as postprandial glycemic peaks.

  18. Inflammasome activation in decompensated liver cirrhosis

    Institute of Scientific and Technical Information of China (English)

    2016-01-01

    Inflammation participates in the pathogenesis of many liver diseases, including liver cirrhosis. Certaininflammatory citokines, such as interleukin (IL)-1β andIL-18, are produced after the activation of a multiproteincomplex known as the inflammasome. Activation of theinflammasome has been documented in several liverdiseases, but its role in the development and progressionof liver cirrhosis or the complications associated withthis disease is still largely unknown. We have recentlystudied the impact of the inflammasome in the sterileinflammatory response that takes place in the asciticfluid of patients with decompensated cirrhosis, providingevidence that activation of the absent in melanoma2 (AIM2) inflammasome is an important response inthese patients. Ascitic fluid-derived macrophages wereable to mount a very robust AIM2-mediated responseeven in the absence of a priming signal, which is usuallyrequired for the full activation of all the inflammasomes.In addition, high level of inflammasome activation inthese patients was associated with a higher degree ofliver disease and an increased incidence of spontaneousbacterial peritonitis. These results may help explain theexacerbated inflammatory response that usually occursin patients with decompensated cirrhosis in the absenceof detectable infections. Thus, inflammasomes shouldbe considered as possible therapeutic targets in sterileinflammatory complications in patients with cirrhosis.

    @@ A high death toll during an earthquake comes not only from injuries related to the destruction of buildings or road accidents but also from sudden death resulting from cardiovascular problems, as clearly shown in reports.~(1,2) The increased rate of cardiovascular mortality during an earthquake has been ascribed to the impact of a major emotional stress on the heart, mediated through an increase in cardiac sympathetic activity~,(1,2) and probably including some other neuroendocrine mechanisms. A rise in blood pressure (BP) and heart rate (HR) may be directly responsible for the increased rate of cardiovascular mortality during an earthquake. Previously published studies about the acute changes of BP and HR used indirect information, usually collected after the events. A little direct information, such as by Parati et al,~3 is not enough for the low-incidence rate of an earthquake and has the obvious technical difficulties in measuring BP during an earthquake. Luckily, we recorded the acute changes of BP and HR of some patients during the earthquake by 24-hour ambulatory blood pressure monitoring, as report below.

    Background A substantial aspect of health literacy is the knowledge of prescribed medication. In chronic heart failure, incomplete intake of prescribed drugs (medication non-adherence) is inversely associated with clinical prognosis. Therefore, we assessed medication knowledge in a cohort of patients with decompensated heart failure at hospital admission and after discharge in a prospective, cross-sectional study. Methods One hundred and eleven patients presenting at the emergency department with acute decompensated heart failure were included (mean age 78.4±9.2, 59% men) in the study. Patients’ medication knowledge was assessed during individual interviews at baseline, course of hospitalization, and 3 months after discharge. Individual responses were compared with the medical records of the referring general practitioner. Results Median N-terminal prohormone of brain natriuretic peptide plasma concentration in the overall population at baseline was 4,208 pg/mL (2,023–7,101 pg/mL [interquartile range]), 20 patients died between the second and third interview. The number of prescribed drugs increased from 8±3 at baseline to 9±3 after 3 months. The majority of patients did not know the correct number of their drugs. Medication knowledge decreased continuously from baseline to the third interview. At baseline, 37% (n=41) of patients stated the correct number of drugs to be taken, whereas only 18% (n=16) knew the correct number 3 months after discharge (P=0.008). Knowledge was inversely related to N-terminal prohormone of brain natriuretic peptide levels. Conclusion Medication knowledge of patients with acute decompensated heart failure is poor. Despite care in a university hospital, patients’ individual medication knowledge decreased after discharge. The study reveals an urgent need for better strategies to improve and promote the knowledge of prescribed medication in these very high-risk patients. PMID:27877025

    Acute decompensated heart failure is a common cause of hospitalisation. This is a period of vulnerability both in altered pathophysiology and also the potential for iatrogenesis due to therapeutic interventions. Renal dysfunction is often associated with heart failure and portends adverse outcomes. Identifying heart failure patients at risk of renal dysfunction is important in preventing progression to chronic kidney disease or worsening renal function, informing adjustment to medication management and potentially preventing adverse events. However, there is no working or consensus definition in international heart failure management guidelines for worsening renal function. In addition, there appears to be no concordance or adaptation of chronic kidney disease guidelines by heart failure guideline development groups for the monitoring of chronic kidney disease in heart failure. Our aim is to encourage the debate for an agreed definition given the prognostic impact of worsening renal function in heart failure. We present the case for the uptake of the Acute Kidney Injury Network criteria for acute kidney injury with some minor alterations. This has the potential to inform study design and meta-analysis thereby building the knowledgebase for guideline development. Definition consensus supports data element, clinical registry and electronic algorithm innovation as instruments for quality improvement and clinical research for better patient outcomes. In addition, we recommend all community managed heart failure patients have their baseline renal function classified and routinely monitored in accordance with established renal guidelines to help identify those at increased risk for worsening renal function or progression to chronic kidney disease.

    A comparative study of changes in the fatty acid composition of rabbit heart and adrenal mitochondria was carried out after acute (1h) immobilization stress. In heart mitochondria the stress induced a decrease in the content of capric, lauric, myristic and pentadecanic acids. A statistically significant reduction of the amount of heptadecanoic, linoleic, arachidonic acids and an increase in the level of palmitic acid was noted in adrenal mitochondria. The acute stress resulted in differently directed shifts in the saturation of fatty acids. An elevation of the sum of unsaturated fatty acids was observed in the heart, and a decrease was detected in the adrenal glands. The above shifts in the fatty acid composition of adrenal and heart mitochondria provide evidence for different directions of lipid metabolism in these organs following stress.

    Full Text Available BACKGROUND: Muscle passive contraction of lower limb by neuromuscular electrostimulation (NMES is frequently used in chronic heart failure (CHF patients but no data are available concerning its action on sympathetic activity. However, Transcutaneous Electrical Nerve Stimulation (TENS is able to improve baroreflex in CHF. The primary aim of the present study was to investigate the acute effect of TENS and NMES compared to Sham stimulation on sympathetic overactivity as assessed by Muscle Sympathetic Nerve Activity (MSNA. METHODS: We performed a serie of two parallel, randomized, double blinded and sham controlled protocols in twenty-two CHF patients in New York Heart Association (NYHA Class III. Half of them performed stimulation by TENS, and the others tested NMES. RESULTS: Compare to Sham stimulation, both TENS and NMES are able to reduce MSNA (63.5 ± 3.5 vs 69.7 ± 3.1 bursts / min, p < 0.01 after TENS and 51.6 ± 3.3 vs 56.7 ± 3.3 bursts / min, p < 0, 01 after NMES. No variation of blood pressure, heart rate or respiratory parameters was observed after stimulation. CONCLUSION: The results suggest that sensory stimulation of lower limbs by electrical device, either TENS or NMES, could inhibit sympathetic outflow directed to legs in CHF patients. These properties could benefits CHF patients and pave the way for a new non-pharmacological approach of CHF.

    Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people. By screening PubMed, Google Scholar, Scopus and JSTOR, fifteen cases were found of which eight were sufficiently documented for full analysis. Blood alcohol levels ranged from 90 to 958 mg/dl (19 to 205 mM). Second and third degree AV block was observed most (6/8) albeit that in two of these patients a vagal stimulus led to deterioration from first into higher order AV block. In all cases, patients reverted to normal sinus rhythm upon becoming sober again. Mildly lowered body temperature (35.9 ± 0.5°C) was observed but can be excluded as a major cause of conduction blockade. We hypothesize that ethanol induced partial inhibition of calcium and potentially also sodium currents in conductive tissue structures may be one of the mechanisms of conduction slowing and block that may become exaggerated upon increased vagal tone. An impairment of gap junction function cannot be excluded as a contributing factor. In conclusion, cases of documented alcohol induced AV block are very rare but events can occur at relatively low serum alcohol levels which should prompt to awareness of this phenomenon in alcohol intoxicated patients.

    Full Text Available Objective: Decreased heart rate variability (HRV has been reported to be a predictor of mortality after myocardial infarction (MI. Patients’ beliefs and perceptions concerning their illness may play a role in decreased HRV. This study investigated if illness perceptions predict HRV at three months following acute MI. Methods: 130 patients referred to a tertiary cardiology centre, were examined within 48 hours and three months following acute MI. At admission, patients’ cognitive representations of their MI were assessed using the German version of the self-rated Brief Illness Perception Questionnaire (Brief IPQ. At admission and after three months (follow-up, frequency and time domain measures of HRV were obtained from 5-min electrocardiogram (ECG recordings during stable supine resting. Results: Linear hierarchical regression showed that the Brief IPQ dimensions timeline (β coefficient = -0.29; p = .044, personal control (β = 0.47; p = .008 and illness understanding (β = 0.43; p = .014 were significant predictors of HRV, adjusted for age, gender, baseline HRV, diabetes, beta-blockers, left ventricular ejection fraction (LVEF, attendance of cardiac rehabilitation, and depressive symptoms. Conclusions: As patients’ negative perceptions of their illness are associated with lower HRV following acute MI, a brief illness perception questionnaire may help to identify patients who might benefit from a specific illness perceptions intervention.

    Hepatitis A virus (HAV) vaccination is recommended in chronic liver disease because of an increased morbidity and mortality associated with HAV superinfection. However, data regarding the efficacy of HAV vaccination in patients with advanced chronic liver disease is limited. We assessed the efficacy of a standard HAV vaccination schedule in decompensated chronic liver disease in comparison with compensated disease and defined clinical predictors associated with seroconversion. Eighty-four anti-HAV antibody-negative patients, 49 with compensated liver disease, and 35 with decompensated disease were enrolled. Seroconversion was measured by qualitative and quantitative anti-HAV antibody measurements 1 month after each vaccine dose, and univariate/multivariate analysis was performed to define clinical predictors associated with seroconversion. One month after the primary dose, 71.4% of patients with compensated liver disease had detectable anti-HAV antibody compared with 37.1% with decompensated liver disease (P decompensated disease (P decompensated disease. On multivariate analysis, Child-Pugh class was the only factor predicting response to vaccination. Seroconversion after HAV vaccination was significantly less common in decompensated liver disease and the presence of advanced disease (Child-Pugh class B/C) predicted a lower response rate. These findings indicate that the response to HAV vaccination in chronic liver disease is optimal when targeted to patients before the development of hepatic decompensation.

    2014-01-01

    Full Text Available There has always been concern in determining the relationship between orthodontic tooth movement and the consequent biological costs to the periodontium and tooth root. The possibility of evaluating the tooth and bone morphology by CBCT allows more accurate analysis of qualitative and quantitative aspects of these processes. This paper presents a case report of a 20-year-old male patient with Class III malocclusion and hyperdivergent facial pattern, who was surgically treated. A significant amount of labial movement of mandibular incisors was performed during orthodontic treatment before surgery. CBCT was used for evaluation of buccal and lingual bone plates before and after tooth decompensation. The changes in the bone insertion level of maxillary and mandibular incisors in the present case encourage a reflection on the treatment protocol in individuals with dentoskeletal discrepancies.

    An 84-year-old woman, who was followed up as hypertrophic obstructive cardiomyopathy (HOCM) in a local hospital, was transferred to our center because of anterior chest pain and diagnosed with acute myocardial infarction (MI). Coronary angiography showed total occlusion of the mid-left anterior descending, and flow was restored after endovascular thrombectomy. An autopsy was performed after she died on hospital day 6. At autopsy, there was no significant stenosis in this vessel and the absence of plaque rupture was confirmed. Likewise, it was unclear asymmetric hypertrophy at autopsy, it could not deny that a sigmoid deformity of the basal septum occurs in elderly patients and can mimic the asymmetric septal hypertrophy of hypertrophic cardiomyopathy. MI was thought to be caused by coronary spasm or squeezing in HOCM-like heart. Therefore, it may be necessary antithrombosis therapy in HOCM-like patients with no history of paroxysmal atrial fibrillation.

    The International Society of Heart and Lung Transplantation (ISHLT) recently updated consensus pediatric heart failure guidelines from those published in 2004 with an aim to provide a practical evidence-based resource whilst recognizing the influence of adult heart failure practice. The new guidelines were formed from published evidence for heart failure management and used parallels with adult literature where pediatric evidence was lacking. This is a summary of the pharmacological therapies discussed in the new 2014 guidelines, emphasizing changes from the previous recommendations with regards to treatment of chronic heart failure with reduced ejection fraction, chronic heart failure with preserved ejection fraction, and acute decompensated heart failure. Each recommendation is classified according to strength and level of evidence. We also discuss future perspectives in the pharmacological treatment of heart failure. The 2014 ISHLT guidelines have evolved considerably from those published in 2004 with extensive information surrounding the underlying pathophysiology, investigations and recommended treatment. The new guidelines contain a modest amount of new pediatric data on pharmacological therapies and extrapolate adult data when appropriate. It is likely that most new recommendations for pediatric heart failure will continue to be based on therapies of proven benefit in adult heart failure studies.

    Atherosclerosis induces the elevation of uric acid (UA), and an elevated UA level is well known to lead to a poor prognosis in patients with acute heart failure (AHF). However, the prognostic value of atherosclerotic risk factors in hyperuricemic AHF patients remains to be elucidated. The data from 928 patients who were admitted to the intensive care unit (ICU) at Nippon Medical School Chiba Hokusoh Hospital between January 2001 and December 2014, and whose serum UA levels were measured were screened. A total of 394 AHF patients with hyperuricemia were enrolled in this study. The patients were assigned to a low-risk group (≤1 atherosclerosis risk factor) and a high-risk group (≥2 atherosclerosis risk factors) according to their number of risk factors. The patients in the low-risk group were more likely to have dilated cardiomyopathy, clinical scenario 3 than those in the high-risk group. The serum total bilirubin, blood urea nitrogen, C-reactive protein, and brain-type natriuretic peptide levels were significantly higher in the low-risk group than the high-risk group (p factors (number = 1, HR (hazard ratio) 0.243, 95 % CI 0.096-0.618, p = 0.003; number = 2, HR 0.253, 95 % CI 0.108-0.593, p = 0.002; number ≥3, HR 0.209, 95 % CI 0.093-0.472, p factors were not associated with a poor prognosis in patients with hyperuricemic AHF.

    Full Text Available Non-Gaussianity index (λ is a new index of heart rate variability (HRV that characterizes increased probability of the large heart rate deviations from its trend. A previous study has reported that increased λ is an independent mortality predictor among patients with chronic heart failure. The present study examined predictive value of λ in patients after acute myocardial infarction (AMI. Among 670 post-AMI patients, we performed 24-hr Holter monitoring to assess λ and other HRV predictors, including standard deviation of normal-to-normal interval, very-low frequency power, scaling exponent α1 of detrended fluctuation analysis, deceleration capacity, and heart rate turbulence (HRT. At baseline, λ was not correlated substantially with other HRV indices (|r| <0.4 with either indices and was decreased in patients taking β-blockers (P = 0.04. During a median follow up period of 25 months, 45 (6.7% patients died (32 cardiac and 13 non-cardiac and 39 recurrent nonfatal AMI occurred among survivors. While all of these HRV indices but λ were significant predictors of both cardiac and non-cardiac deaths, increased λ predicted exclusively cardiac death (RR [95% CI], 1.6 [1.3-2.0] per 1 SD increment, P <0.0001. The predictive power of increased λ was significant even after adjustments for clinical risk factors, such as age, diabetes, left ventricular function, renal function, prior AMI, heart failure, and stroke, Killip class, and treatment ([95% CI], 1.4 [1.1-2.0] per 1 SD increment, P = 0.01. The prognostic power of increased λ for cardiac death was also independent of all other HRV indices and the combination of increased λ and abnormal HRT provided the best predictive model for cardiac death. Neither λ nor other HRV indices was an independent predictor of AMI recurrence. Among post-AMI patients, increased λ is associated exclusively with increased cardiac mortality risk and its predictive power is independent of clinical risk factors and

    Full Text Available Background: There is paucity of data on heart failure (HF in the Gulf Middle East. The present paper describes the rationale, design, methodology and hospital characteristics of the first Gulf acute heart failure registry (Gulf CARE. Materials and Methods: Gulf CARE is a prospective, multicenter, multinational registry of patients >18 year of age admitted with diagnosis of acute HF (AHF. The data collected included demographics, clinical characteristics, etiology, precipitating factors, management and outcomes of patients admitted with AHF. In addition, data about hospital readmission rates, procedures and mortality at 3 months and 1-year follow-up were recorded. Hospital characteristics and care provider details were collected. Data were entered in a dedicated website using an electronic case record form. Results: A total of 5005 consecutive patients were enrolled from February 14, 2012 to November 13, 2012. Forty-seven hospitals in 7 Gulf States (Oman, Saudi Arabia, Yemen, Kuwait, United Gulf Emirates, Qatar and Bahrain participated in the project. The majority of hospitals were community hospitals (46%; 22/47 followed by non-University teaching (32%; 15/47 and University hospitals (17%. Most of the hospitals had intensive or coronary care unit facilities (93%; 44/47 with 59% (28/47 having catheterization laboratory facilities. However, only 29% (14/47 had a dedicated HF clinic facility. Most patients (71% were cared for by a cardiologist. Conclusions: Gulf CARE is the first prospective registry of AHF in the Middle East, intending to provide a unique insight into the demographics, etiology, management and outcomes of AHF in the Middle East. HF management in the Middle East is predominantly provided by cardiologists. The data obtained from this registry will help the local clinicians to identify the deficiencies in HF management as well as provide a platform to implement evidence based preventive and treatment strategies to reduce the burden

    Acute kidney injury (AKI) is closely associated with the mortality of hospitalized patients and long-term development of chronic kidney disease, especially in children. The purpose of our study was to assess the evidence of contrast-induced AKI after cardiac catheterization in children with heart disease and evaluate the clinical usefulness of candidate biomarkers in AKI. A total of 26 children undergoing cardiac catheterization due to various heart diseases were selected and urine and blood samples were taken at 0 hr, 6 hr, 24 hr, and 48 hr after cardiac catheterization. Until 48 hr after cardiac catheterization, there was no significant increase in serum creatinine level in all patients. Unlike urine kidney injury molecule-1, IL-18 and neutrophil gelatinase-associated lipocalin, urine liver-type fatty acid-binding protein (L-FABP) level showed biphasic pattern and the significant difference in the levels of urine L-FABP between 24 and 48 hr. We suggest that urine L-FABP can be one of the useful biomarkers to detect subclinical AKI developed by the contrast before cardiac surgery.

    Our objective is to determine the incidence, etiology, risk factors and outcome of acute kidney injury (AKI) after open heart surgery. A prospective study was conducted on 62 patients who underwent open heart surgery and were followed-up for the development of AKI and to determine its incidence, etiology and outcome. Post-operative AKI was considered when the post-operative serum creatinine was >1.5 mg/dL or there was doubling of serum creatinine above the baseline (pre-operative) with a prior normal renal function. The incidence of AKI in the post-operative period in our study was 17.7%. The common etiological factors for AKI in our study were sepsis, hypotension, prolonged need for ventilator and inotropic support and drugs given in the post-operative period. The important risk factors for the development of AKI in the post-operative period were hypertension, diabetes mellitus, gout, prolonged total bypass time and prolonged aortic cross-clamp time. The overall mortality in our study subjects was 11.3% (seven of 62 died) and the mortality in the patients who developed post-operative AKI was 71.4%.

    Full Text Available Acute nitric oxide synthase inhibition with N G-nitro-L-arginine methyl ester (L-NAME on chronotropic and pressor responses was studied in anesthetized intact rats and rats submitted to partial and complete autonomic blockade. Blood pressure and heart rate were monitored intra-arterially. Intravenous L-NAME injection (7.5 mg/kg elicited the same hypertensive response in intact rats and in rats with partial (ganglionic and parasympathetic blockade and complete autonomic blockade (38 ± 3, 55 ± 6, 54 ± 5, 45 ± 5 mmHg, respectively; N = 9, P = NS. L-NAME-induced bradycardia at the time when blood pressure reached the peak plateau was similar in intact rats and in rats with partial autonomic blockade (43 ± 8, 38 ± 5, 46 ± 6 bpm, respectively; N = 9, P = NS. Rats with combined autonomic blockade showed a tachycardic response to L-NAME (10 ± 3 bpm, P<0.05 vs intact animals, N = 9. Increasing doses of L-NAME (5.0, 7.5 and 10 mg/kg, N = 9 caused a similar increase in blood pressure (45 ± 5, 38 ± 3, 44 ± 9 mmHg, respectively; P = NS and heart rate (31 ± 4, 34 ± 3, 35 ± 4 bpm, respectively; P = NS. Addition of L-NAME (500 µM to isolated atria from rats killed by cervical dislocation and rats previously subjected to complete autonomic blockade did not affect spontaneous beating or contractile strength (N = 9. In vivo results showed that L-NAME promoted a tachycardic response in rats with complete autonomic blockade, whereas the in vitro experiments showed no effect on intrinsic heart rate, suggesting that humoral mechanisms may be involved in the L-NAME-induced cardiac response.

    Heat shock protein 60 (HSP60) is a mitochondrial protein constitutively expressed in the majority of cells, and its expression is up-regulated by a variety of stressors. In heart failure, HSP60 is released from cardiomyocytes. The authors speculate that increased serum HSP60 (sHSP60) may be related to the severity of heart failure. This investigation sought to assess the association between sHSP60 and the composite end point of death/readmission in patients with acute heart failure (AHF). A total of 132 consecutive patients were admitted for AHF. The independent association between sHSP60 and the end point was assessed with Cox regression. During a median follow-up of 7 months (interquartile range, 3-14), 35 (26.5%) deaths, 40 (30.3%) readmissions, and 65 (49.2%) deaths/readmission were identified. Patients who exhibited the outcome showed higher median sHSP60 values (6.15 ng/mL [8.49] vs 4.71 ng/mL [7.55] P=.010). A monotonic increase in the incidence of the composite end point was observed when moving from lower to higher tertile (4.74, 4.76, and 6.98 per 10 patients-years of follow-up, P for trend <.001). After adjusting for established risk factors, only patients in the upper tertile showed an increased risk of death/readmission (hazard ratio, 2.63; 95% confidence interval, 1.29-5.37; P=.008). In patients with AHF, high sHSP60 was related to a higher risk for subsequent death/readmission for AHF.

They have been detected in heart failure (HF and are associated with a bad prognosis. OBJECTIVE: To evaluate the association of cardiac troponin T (cTnT and its ranges with prognosis in decompensated HF. METHODS: A total of 70 patients with chronic HF worsening that needed hospitalization were studied. Cox model was used to evaluate the variables at admission capable of predicting the combined outcome that consisted of death or re-hospitalization due to HF worsening during a 1-year follow-up. RESULTS: During the follow-up, there were 44 deaths, 36 re-hospitalizations due to HF and 56 combined outcomes.

    Heart failure (HF) afflicts nearly 6 million Americans, resulting in one million emergency department (ED) visits and over one million annual hospital discharges. An aging population and improved survival from cardiovascular diseases is expected to further increase HF prevalence. Emergency providers play a significant role in the management of patients with acute heart failure (AHF). It is crucial that emergency physicians and other providers involved in early management understand the latest developments in diagnostic testing, therapeutics and alternatives to hospitalization. Further, clinical trials must be conducted in the ED in order to improve the evidence base and drive optimal initial therapy for AHF. Should ongoing and future studies suggest early phenotype-driven therapy improves in-hospital and post-discharge outcomes, ED treatment decisions will need to evolve accordingly. The potential impact of future studies which incorporate risk-stratification into ED disposition decisions cannot be underestimated. Predictive instruments that identify a cohort of patients safe for ED discharge, while simultaneously addressing barriers to successful outpatient management, have the potential to significantly impact quality of life and resource expenditures.

    AIMS: To study the prognostic importance of left ventricular systolic function in patients with heart failure (HF) and acute myocardial infarction (AMI) with respect to the presence of prior heart failure and known ischemic heart disease. METHODS: In 13,084 consecutive patients diagnosed...... with either AMI or HF, a medical history and an echocardiographic assessment of left ventricular systolic function by wall motion index (WMI) were obtained. Patients were divided into four groups: AMI with or without a history of HF, and primary HF (no recent AMI) with or without a history of ischemic heart...... disease (IHD). Mortality was assessed after nine years of follow-up. RESULTS: WMI stratified patients according to all-cause mortality in all four groups of patients (p

    Increased neurohumoral stimulation resulting in excessive sodium avidity and extracellular volume overload are hallmark features of decompensated heart failure. Especially in case of concomitant renal dysfunction, the kidneys often fail to elicit effective natriuresis. While assessment of renal function is generally performed by measuring serum creatinine-a surrogate for glomerular filtration-, this only represents part of the nephron's function. Alterations in tubular sodium handling are at least equally important in the development of volume overload and congestion. Venous congestion and neurohumoral activation in advanced HF further promote renal sodium and water retention. Interestingly, early on, before clinical signs of heart failure are evident, intrinsic renal derangements already impair natriuresis. This clinical review discusses the importance of heart failure (HF) induced changes in different nephron segments. A better understanding of cardiorenal interactions which ultimately result in sodium avidity in HF might help to treat and prevent congestion in chronic and acute HF.

    Electrocardiogram and arterial pressure measurements were studied under acute exposures to WIFI (2.45GHz) during one hour in adult male rabbits. Antennas of WIFI were placed at 25cm at the right side near the heart. Acute exposure of rabbits to WIFI increased heart frequency (+22%) and arterial blood pressure (+14%). Moreover, analysis of ECG revealed that WIFI induced a combined increase of PR and QT intervals. By contrast, the same exposure failed to alter maximum amplitude and P waves. After intravenously injection of dopamine (0.50ml/kg) and epinephrine (0.50ml/kg) under acute exposure to RF we found that, WIFI alter catecholamines (dopamine, epinephrine) action on heart variability and blood pressure compared to control. These results suggest for the first time, as far as we know, that exposure to WIFI affect heart rhythm, blood pressure, and catecholamines efficacy on cardiovascular system; indicating that radiofrequency can act directly and/or indirectly on cardiovascular system.

    Two groups of patients, one under 40 years of age and the other 40 years and over, were divided into subgroups according to whether they had symptoms associated with near vision. A method developed in 'signal detection theory' was used to determine whether a value could be found for heterophoria, or associated heterophoria, which would predict which patients had symptoms due to decompensated heterophoria in normal routine investigation. Receiver operator characteristic curves (ROC curves) were constructed to look for these cut-off values between patients with, and without, symptoms. No value for dissociated heterophoria was found that would discriminate between the symptomatic and asymptomatic patients. It is concluded that heterophoria measurement is not useful as a routine procedure. In the case of associated heterophoria, for the under 40 years age group, patients with a value of 1 prism dioptre or more are more likely to have symptoms than not, and one-third of patients with close work problems have a value of 2 prism dioptres or more. It was rare to find any asymptomatic patient with a value as high as this. In the 40 years and over age group those with an associated heterophoria of 2 prism dioptres or more are more likely to have symptoms than not. One-third of patients in the latter age group, with symptoms, have a value of 3 prism dioptres or more whilst it is rare to find an asymptomatic patient with a value as large as this.

    Nearly a third of patients with acute heart failure experience concomitant renal dysfunction. This condition is often associated with increased costs of care, length of hospitalisation and high mortality. Although the clinical impact of chronic kidney disease (CKD) has been well established, the exact clinical significance of worsening renal function (WRF) during the acute and post-hospitalisation phases is not completely understood. Therefore, it is still unclear which of the common laboratory markers are able to identify WRF at an early stage. Recent studies comparing CKD with WRF showed contradictory results; this could depend on a different WRF definition, clinical characteristics, haemodynamic disorders and the presence of prior renal dysfunction in the population enrolled. The current definition of acute cardiorenal syndrome focuses on both the heart and kidney but it lacks precise laboratory marker cut-offs and a specific diagnostic approach. WRF and CKD could represent different pathophysiological mechanisms in the setting of acute heart failure; the traditional view includes reduced cardiac output with systemic and renal vasoconstriction. Nevertheless, it has become a mixed model that encompasses both forward and backward haemodynamic dysfunction. Increased central venous pressure, renal congestion with tubular obliteration, tubulo-glomerular feedback and increased abdominal pressure are all potential additional contributors. The impact of WRF on patients who experience preserved renal function and individuals affected with CKD is currently unknown. Therefore it is extremely important to understand the origins, the clinical significance and the prognostic impact of WRF on CKD.

    BACKGROUND: Stroke is a common presentation in geriatric patients in emergency department but rarely seen in pediatric patients. In case of acute ischemic stroke in pediatric age group, management is different from that of adult ischemic stroke where thrombolysis is a good op. METHODS: We report a case of a 17-year-old male child presenting in emergency with an episode of acute ischemic stroke causing left hemiparesis with left facial weakness and asymmetry. The patient suffered from cyanotic congenital heart disease for which he had undergone Fontan operation previously. He had a history of missing his daily dose of warfarin for last 3 days prior to the stroke. RESULTS: The patient recovered from acute ischemic stroke without being thrombolyzed. CONCLUSION: In pediatric patients, acute ischemic stroke usually is evolving and may not require thrombolysis. PMID:25215056

  14. Acute tryptophan depletion attenuates brain-heart coupling following external feedback

    Full Text Available External and internal performance feedback triggers neural and visceral modulations such as reactions in the medial prefrontal cortex and insulae or changes of heart period (HP. The functional coupling of neural and cardiac responses following feedback (cortico-cardiac connectivity is not well understood. While linear time-lagged within-subjects correlations of single-trial EEG and HP (cardio-electroencephalographic covariance-tracing, CECT indicate a robust negative coupling of EEG magnitude 300 ms after presentation of an external feedback stimulus with subsequent alterations of heart period (the so-called N300H phenomenon, the neurotransmitter systems underlying feedback-evoked cortico-cardiac connectivity are largely unknown. Because it has been shown that acute tryptophan depletion (ATD, attenuating brain serotonin (5-HT, decreases cardiac but not neural correlates of feedback processing, we hypothesized that 5-HT may be involved in feedback-evoked cortico-cardiac connectivity. In a placebo-controlled double-blind crossover design, twelve healthy participants received a tryptophan-free amino-acid drink at one session and a balanced amino-acid control-drink on another and twice performed a time-estimation task with feedback presented after each trial. N300H magnitude and plasma tryptophan levels were assessed. Results indicated a robust N300H after the control drink, which was significantly attenuated following ATD. Moreover, plasma tryptophan levels during the control session were correlated with N300H amplitude such that individuals with lower tryptophan levels showed reduced N300H. Together, these findings indicate that 5-HT is important for feedback-induced covariation of cortical and cardiac activity. Because individual differences in anxiety have previously been linked to 5-HT, cortico-cardiac coupling and feedback processing, the present findings may be particularly relevant for futures studies linking 5-HT to anxiety.

    The study investigated the heart rate (HR) and heart rate variability (HRV) before, during, and after stretching exercises performed by subjects with low flexibility levels. Ten men (age: 23 ± 2 years; weight: 82 ± 13 kg; height: 177 ± 5 cm; sit-and-reach: 23 ± 4 cm) had the HR and HRV assessed during 30 minutes at rest, during 3 stretching exercises for the trunk and hamstrings (3 sets of 30 seconds at maximum range of motion), and after 30 minutes postexercise. The HRV was analyzed in the time ('SD of normal NN intervals' [SDNN], 'root mean of the squared sum of successive differences' [RMSSD], 'number of pairs of adjacent RR intervals differing by >50 milliseconds divided by the total of all RR intervals' [PNN50]) and frequency domains ('low-frequency component' [LF], 'high-frequency component' [HF], LF/HF ratio). The HR and SDNN increased during exercise (p stretching (p = 0.03) and increased along recovery (p = 0.03). At the end of recovery, HR was lower (p = 0.01), SDNN was higher (p = 0.02), and PNN50 was similar (p = 0.42) to pre-exercise values. The LF increased (p = 0.02) and HF decreased (p = 0.01) while stretching, but after recovery, their values were similar to pre-exercise (p = 0.09 and p = 0.3, respectively). The LF/HF ratio increased during exercise (p = 0.02) and declined during recovery (p = 0.02), albeit remaining higher than at rest (p = 0.03). In conclusion, the parasympathetic activity rapidly increased after stretching, whereas the sympathetic activity increased during exercise and had a slower postexercise reduction. Stretching sessions including multiple exercises and sets acutely changed the sympathovagal balance in subjects with low flexibility, especially enhancing the postexercise vagal modulation.

    Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.

    Exposure to racial discrimination has been linked to physiological reactivity. This study investigated self-reported exposure to racial discrimination and parasympathetic [high-frequency heart rate variability (HF-HRV)] and sympathetic (norepinephrine and cortisol) activity at baseline and then again after acute laboratory stress. Lifetime exposure to racial discrimination was measured with the Schedule of Racist Events scale. Thirty-two women (16 Black and 16 White) with type 2 diabetes performed a public speaking stressor. Beat-to-beat intervals were recorded on electrocardiograph recorders, and HF-HRV was calculated using spectral analysis and natural log transformed. Norepinephrine and cortisol were measured in blood. Higher discrimination predicted lower stressor HF-HRV, even after controlling for baseline HF-HRV. When race, age, A1c and baseline systolic blood pressure were also controlled, racial discrimination remained a significant independent predictor of stressor HF-HRV. There was no association between lifetime discrimination and sympathetic markers. In conclusion, preliminary data suggest that among women with type 2 diabetes mellitus (T2DM), exposure to racial discrimination is adversely associated with parasympathetic, but not sympathetic, reactivity.

    Full Text Available The presence and type of viral genomes have been suggested as the main etiology for inflammatory dilated cardiomyopathy. Information on the clinical implication of this finding in a large population of children is lacking. We evaluated the prevalence, type, and clinical impact of specific viral genomes in endomyocardial biopsies (EMB collected between 2001 and 2013 among 63 children admitted to our hospital for acute heart failure (median age 2.8 years. Viral genome was searched by polymerase chain reaction (PCR. Patients underwent a complete two-dimensional echocardiographic examination at hospital admission and at discharge and were followed-up for 10 years. Twenty-seven adverse events (7 deaths and 20 cardiac transplantations occurred during the follow-up. Viral genome was amplified in 19/63 biopsies (35%; PVB19 was the most commonly isolated virus. Presence of specific viral genome was associated with a significant recovery in ejection fraction, compared to patients without viral evidence (p < 0.05. In Cox-regression analysis, higher survival rate was related to virus-positive biopsies (p < 0.05. When comparing long-term prognosis among different viral groups, a trend towards better prognosis was observed in the presence of isolated Parvovirus B19 (PVB19 (p = 0.07. In our series, presence of a virus-positive EMB (mainly PVB19 was associated with improvement over time in cardiac function and better long-term prognosis.

    The aims of this study were to evaluate left atrial size in cats with acute left-sided congestive heart failure. We hypothesized that left atrial size as determined by thoracic radiography can be normal in cats with acute left-sided congestive heart failure. One hundred cats with acute left-sided congestive heart failure in which thoracic radiography and echocardiography were performed within 12 h were identified. Left atrial size was evaluated using right lateral and ventrodorsal radiographs. Measurements were compared to two-dimensional echocardiographic variables of left atrial size and left ventricular size. On echocardiography, left atrial enlargement was observed in 96% cats (subjective assessment) whereas maximum left atrial dimension was increased (>15.7 mm) in 93% cats. On radiographs left atrial enlargement (subjective assessment) was found in 48% (lateral view), 53% (ventrodorsal view), and 64% (any view) of cats whereas left atrial enlargement was absent in 36% of cats in both views. Agreement between both methods of left atrial size estimation was poor (Cohen's kappa 0.17). Receiver operating characteristic curve analysis identified a maximum echocardiographic left atrial dimension of approximately 20 mm as the best compromise (Youden index) between sensitivity and specificity in the prediction of radiographic left atrial enlargement. Left atrial enlargement as assessed by thoracic radiography may be absent in a clinically relevant number of cats with congestive heart failure. Therefore, normal left atrial size on thoracic radiographs does not rule out presence of left-sided congestive heart failure in cats with clinical signs of respiratory distress.

    Objective:To analyze the effect of sequential mechanical ventilation on improving hemodynamics, cardiac function and neurohumoral status in elderly patients with acute left heart failure.Methods:A total of 90 cases of elderly patients with acute left heart failure were randomly divided into observation group and control group, control group received conventional mechanical ventilation therapy, observation group received sequential mechanical ventilation, and then differences in hemodynamics, cardiac function and neurohumoral status were compared between two groups after treatment.Results:24 h after treatment, mPAP, PCWP and RAP levels of observation group after treatment were lower than those of control group, and CO level was higher than that of control group; LVEF value was higher than that of control group, and SVR, LVEDV and LVESV values were lower than those of control group; 12 h and 24 h after treatment, plasma Nt-proBNP, ANP, R, AngⅡ and ALD levels of observation group were significantly lower than those of control group.Conclusion:Sequential mechanical ventilation can optimize the illness in elderly patients with acute left heart failure, and plays a positive role in promoting patients' cardiac function recovery, restoring homeostasis and other aspects.

  6. Treatment of Hepatitis B in Decompensated Liver Cirrhosis

    Richard Guan

    2011-01-01

    Full Text Available Chronic hepatitis B infection progresses from an asymptomatic persistently infected state to chronic hepatitis, cirrhosis, decompensated liver disease, and/or hepatocellular carcinoma. About 3% of patients with chronic hepatitis develop cirrhosis yearly, and about 5% of individuals with hepatitis B cirrhosis become decompensated annually. The outcome for patients with decompensated cirrhosis is bleak. Lamivudine, the first oral antiviral agent available for hepatitis B treatment is safe and effective and can improve or stabilize liver disease in patients with advanced cirrhosis and viraemia. Viral resistance restricts its prolonged use. Entecavir and tenofovir are newer agents with excellent resistance profile to date. These and some other antiviral agents are being investigated for optimal use in this rather challenging patient group.

  7. Decompensated porto-pulmonary hypertension in a cirrhotic patient with thrombosis of portocaval shunt

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    We report a case of decompensated porto-pulmonary hypertension closely associated with the development of intra-portocaval shunt thrombosis. A woman with Laennec's cirrhosis was hospitalized because of severe dyspnea and edema. She underwent surgical portocaval anastomosis ten years ago. Imaging studies showed massive intra-shunt thrombosis, portal hypertension, ascites, pleuro-pericardial effusions and enlargement of right cardiac cavities. Cardiac catheterization allowed to rule out coronary and leftsided heart abnormalities and led to the diagnosis of pre-capillary pulmonary hypertension. Antithrombotic treatment with low molecular weight heparin was instituted. The management also included ACE inhibitors,spironolactone, low-salt diet and lactulose. The patient was discharged and three months later we observed the disappearance of edema, ascites and pleuropericardial effusions, a marked body weight reduction and improved dyspnea and liver function tests. A possible link between the development of intra-shunt thrombosis and clinical decompensation in our patient was hypothesized. In fact, it has been demonstrated that the increased portal pressure, caused by occlusion of portosystemic shunt, reduces renal plasma flow and increases systemic endothelin-1 concentration. In our patient the disappearance of edematous state and improved dyspnea observed after recanalization of the shunt strongly support this hypothesis.

    2011-01-01

    Purpose To describe the clinical features and response to treatment of patients with decompensated monofixation syndrome (MFS) and to propose a hypothesis for a decompensation mechanism in such patients. Methods Fourteen adults with MFS who had been symptomatically stable for a mean duration of 25 years developed diplopia in the absence of neurologic or orbital disease. After retrospective chart review, they underwent detailed orthoptic testing. Results from this cross-sectional analysis were compared with similar data from 16 control subjects with stable MFS. Results Compared to stable MFS patients, decompensated subjects had significantly poorer horizontal fusional amplitudes but greater torsional fusional amplitudes; they were also more likely to have a small vertical strabismus and to have received initial treatment later. Stable subjects, however, also had subnormal horizontal as well as torsional fusional amplitudes. There was no difference between groups with respect to refractive error, amblyopia, type or prior treatment of strabismus, stereoacuity, or angle of deviation. After treatment, all patients regained monofixational alignment, but up to one-third had continued diplopia. Symptoms recurred in two patients whose treatment was initially successful. Conclusions Patients with MFS lose fusional amplitudes over time. In some cases this results in development of sensory torsion with secondary decompensation and diplopia. The rate of decompensation averages 7% per year from ages 20 to 70. Treatment for decompensation offers excellent motor results, but sensory symptoms may persist and recurrent symptoms may develop. Monitoring and maintenance of fusional vergence amplitudes should be part of the routine care for patients with MFS. PMID:22253490

  9. Emergency management of decompensated peripartum cardiomyopathy

    2009-01-01

    Full Text Available Peripartum cardiomyopathy (PPCM is a rare life-threatening cardiomyopathy of unknown cause that occurs in the peripartum period in previously healthy women. [1] the symptomatic patients should receive standard therapy for heart failure, managed by a multidisciplinary team. The diagnosis of PPCM rests on the echocardiographic identification of new left ventricular systolic dysfunction during a limited period surrounding parturition. Diagnostic criteria include an ejection fraction of less than 45%, fractional shortening of less than 30%, or both, and end-diastolic dimension of greater than 2.7 cm/m 2 body surface-area. This entity presents a diagnostic challenge because many women in the last month of a normal pregnancy experience dyspnea, fatigue, and pedal edema, symptoms identical to early congestive heart failure. There are no specific criteria for differentiating subtle symptoms of heart failure from normal late pregnancy. Therefore, it is important that a high index of suspicion be maintained to identify the rare case of PPCM as general examination showing symptoms of heart failure with pulmonary edema. PPCM remains a diagnosis of exclusion. No additional specific criteria have been identified to allow distinction between a peripartum patient with new onset heart failure and left ventricular systolic dysfunction as PPCM and another form of dilated cardiomyopathy. Therefore, all other causes of dilated cardiomyopathy with heart failure must be systematically excluded before accepting the designation of PPCM. Recent observations from Haiti [2] suggest that a latent form of PPCM without clinical symptoms might exist. The investigators identified four clinically normal postpartum women with asymptomatic systolic dysfunction on echocardiography, who subsequently either developed clinically detectable dilated cardiomyopathy or improved and completely recovered heart function.

  11. Loss of the AE3 Cl-/HCO3- exchanger in mice affects rate-dependent inotropy and stress-related AKT signaling in heart

    2013-12-01

    Full Text Available Cl-/HCO3- exchangers are expressed abundantly in cardiac muscle, suggesting that HCO3- extrusion serves an important function in heart. Mice lacking Anion Exchanger Isoform 3 (AE3, a major cardiac Cl-/HCO3- exchanger, appear healthy, but loss of AE3 causes decompensation in a hypertrophic cardiomyopathy (HCM model. Using intra-ventricular pressure analysis, in vivo pacing, and molecular studies we identified physiological and biochemical changes caused by loss of AE3 that may contribute to decompensation in HCM. AE3-null mice had normal cardiac contractility under basal conditions and after -adrenergic stimulation, but pacing of hearts revealed that frequency-dependent inotropy was blunted, suggesting that AE3-mediated HCO3- extrusion is required for a robust force-frequency response (FFR during acute biomechanical stress in vivo. Modest changes in expression of proteins that affect Ca2+-handling were observed, but Ca2+-transient analysis of AE3-null myocytes showed normal twitch-amplitude and Ca2+-clearance. Phosphorylation and expression of several proteins implicated in HCM and FFR, including phospholamban, myosin binding protein C, and troponin I were not altered in hearts of paced AE3-null mice; however, phosphorylation of Akt, which plays a central role in mechanosensory signaling, was significantly higher in paced AE3-null hearts than in wild-type controls and phosphorylation of AMPK, which is affected by Akt and is involved in energy metabolism and some cases of HCM, was reduced. These data show loss of AE3 leads to impaired rate-dependent inotropy, appears to affect mechanical stress-responsive signaling, and reduces activation of AMPK, which may contribute to decompensation in heart failure.

    2006-05-20

    Three girls of Moroccan descent, aged 9, 10 and 7 years, presented with fever, joint pain and other symptoms. After Streptococcus infection and carditis were confirmed and the Jones criteria for acute rheumatic fever were met, the patients were treated with penicillin and acetylsalicylic acid. All 3 patients recovered. However, the second girl presented 2 months later with cardiac decompensation caused by valve disorders, after which aortic and mitral valvuloplasty was performed. The third girl developed joint pain again after 3 weeks and was diagnosed with juvenile idiopathic arthritis; treatment was adjusted accordingly. The prevalence of rheumatic heart diseases is 10-20 times higher in developing countries than in industrialised nations. The diagnosis 'acute rheumatic fever' should be considered in children of school age with unexplained fever, also when the Jones criteria have not yet been met. This may apply to migrant children in particular.

    Full Text Available Background: Acute Lower Respiratory Tract Infection (ALRTI is the leading cause of deaths in children under 5 years of age worldwide, and has high morbidity and mortality in children with Congenital Heart Disease (CHD. The objective of this study was to obtain the incidence, clinical characteristic, and outcome of ALRTI children with CHD. Methods: A retrospective hospital-based study was conducted from January 2007–December 2011 to medical record of child patients with ALRTI and CHD in the Department of Child Health of Dr. Hasan Sadikin General Hospital, Bandung. The diagnosis of CHD was determined by echocardiography. The collected data was analyzed and presented in percentage shown in tables. Results : From 3,897 children who had ALRTI, there were 149 children with CHD (3.8%, with 11.4% of whom founded with recurrent episodes. This happened often in girls than boys with quite similar ratio of 1.37: 1.The majority of children (80% was under 1 year old of age, 72.5% with malnutrition, and 24.8% with severe malnutrition. Clinical symptoms mostly found were difficulty of breathing (98%, fever (85.2%, cough (75.2%, and runny nose (63.1%. The most common types of CHD were Patent Ductus Arteriosus (47.6%, followed by Ventricular Septal Defect (47%. Bronchopneumonia (86.6% was the common type of ALRTI. The length of stay was mostly less than 10 days (70.5%. From all the children 43.7% had complications, and 6.7% died. Conclusions: The ALRTI in children with CHD is not common and has good outcome. The majority for CHD lesions are Patent Ductus Arteriosus and Ventricular Septal Defect while for ALRTI is Bronchopneumonia.

    Neurological disorders are associated with autonomic dysfunction. Hippotherapy (HT) is a therapy treatment strategy that utilizes a horse in an interdisciplinary approach for the physical and mental rehabilitation of people with physical, mental and/or psychological disabilities. However, no studies have been carried out which evaluated the effects of HT on the autonomic control in these patients. Therefore, the objective of the present study was to investigate the effects of a single HT session on cardiovascular autonomic control by time domain and non-linear analysis of heart rate variability (HRV). The HRV signal was recorded continuously in twelve children affected by neurological disorders during a HT session, consisting in a 10-minute sitting position rest (P1), a 15-minute preparatory phase sitting on the horse (P2), a 15-minute HT session (P3) and a final 10-minute sitting position recovery (P4). Time domain and non-linear HRV indices, including Sample Entropy (SampEn), Lempel-Ziv Complexity (LZC) and Detrended Fluctuation Analysis (DFA), were calculated for each treatment phase. We observed that SampEn increased during P3 (SampEn=0.56±0.10) with respect to P1 (SampEn=0.40±0.14, p<0.05), while DFA decreased during P3 (DFA=1.10±0.10) with respect to P1 (DFA=1.26±0.14, p<0.05). A significant SDRR increase (p<0.05) was observed during the recovery period P4 (SDRR=50±30ms) with respect to the HT session period P3 (SDRR=30±10ms). Our results suggest that HT might benefit children with disabilities attributable to neurological disorders by eliciting an acute autonomic response during the therapy and during the recovery period.

  15. Using decision trees to manage hospital readmission risk for acute myocardial infarction, heart failure, and pneumonia.

    2014-12-01

    To improve healthcare quality and reduce costs, the Affordable Care Act places hospitals at financial risk for excessive readmissions associated with acute myocardial infarction (AMI), heart failure (HF), and pneumonia (PN). Although predictive analytics is increasingly looked to as a means for measuring, comparing, and managing this risk, many modeling tools require data inputs that are not readily available and/or additional resources to yield actionable information. This article demonstrates how hospitals and clinicians can use their own structured discharge data to create decision trees that produce highly transparent, clinically relevant decision rules for better managing readmission risk associated with AMI, HF, and PN. For illustrative purposes, basic decision trees are trained and tested using publically available data from the California State Inpatient Databases and an open-source statistical package. As expected, these simple models perform less well than other more sophisticated tools, with areas under the receiver operating characteristic (ROC) curve (or AUC) of 0.612, 0.583, and 0.650, respectively, but achieve a lift of at least 1.5 or greater for higher-risk patients with any of the three conditions. More importantly, they are shown to offer substantial advantages in terms of transparency and interpretability, comprehensiveness, and adaptability. By enabling hospitals and clinicians to identify important factors associated with readmissions, target subgroups of patients at both high and low risk, and design and implement interventions that are appropriate to the risk levels observed, decision trees serve as an ideal application for addressing the challenge of reducing hospital readmissions.

    Objective: To research the protective effect of acupuncture on the cardiac performance and cerebral function in acute ischemic stroke (AIS) patients. Methods: Forty AIS patients were randomly divided into acupuncture group (n=20) and medication group (n=20) according to their admission sequence. Acupoints, bilateral Neiguan (PC 6) end Tongli (HT 5) were punctured with Gauge-28 filiform needles, once daily, with 10 sessions being a therapeutic course. Patients of the medication group were treated with oral administration of persantine and aspirin as well as intravenous drip of 20% mannitol, low molecular dextran and compound Danshen (red sage root) injectio. Cerebral infarction volume, ECG (heart rate, STⅡ and TⅡ ), plasma CGRP, thromboxane (TX) B2 and 6-Keto-prostanglandin (PG) F1a and scores of the neurological deficit were used as the indexes. Results: After 2 courses of treatment, self comparison of pre- and post treatment of each group showed that the therapeutic effects of acupuncture in reducing infarction volume ( P< 0.01 ), lowering heart rate (HR, P< 0.01 ) and STⅡ ( P<0.01 ), raising TⅡ wave amplitude (P < 0.01 ), elevating plasma CGRP ( P < 0.001 ) and 6-keto-PGF la ( P < 0.01 ) and reducing plasma TXB2 ( P <0.01) were superior to those of medication group. Conclusion: Acupuncture of acupoints of the Pericardium Meridian and Heart Meridian has a significant protective action on the cardiac performance and cerebral function in acute ischemic stroke patients.

    The cardiorenal syndrome is an interdisciplinary challenge with increasing health economic relevance. Renal failure is a strong predictor for mortality in patients with severe congestive heart failure (CHF) and CHF is one of the fastest increasing morbidities in western countries. For successful therapy a close cooperation between cardiology und nephrology is required. Moreover, a good compliance of the patient is needed to improve symptoms and to reduce the frequency of cardiac decompensation. A broad cardiological and nephrological evaluation and consideration of optimal conservative options according to national and international guidelines are essential. However, a renal replacement therapy might be helpful in patients with refractory heart failure even if they are not dialysis-dependent. In cases of acute heart and renal failure an intensive care management might be necessary to reduce volume overload with the help of extracorporeal ultrafiltration or a dialysis modality. Nevertheless, in cases of chronic refractory CHF peritoneal dialysis should be preferred. The first analysis of the registry of the German Society of Nephrology (http://www.herz-niere.de) confirmed that there is a benefit for health-related quality of life in chronic CHF patients treated with peritoneal dialysis.

    Using localized proton magnetic resonance spectroscopy ({sup 1}H-MRS), accumulation of branchedchain amino acids (BCAA) and their corresponding 2-oxo acids (BCOA) could be non-invasively demonstrated in the brain of a 9-year-old girl suffering from classical maple syrup urine disease. During acute metabolic decompensation, the compounds caused a signal at a chemical shift of 0.9 ppm which was assigned by in vitro experiments. The brain tissue concentration of the sum of BCAA and BCOA could be estimated as 0.9 mmol/l. Localized {sup 1}H-MRS of the brain appears to be suitable for examining patients suffering from maple syrup urine disease in different metabolic states. (orig.)

    Full Text Available CONTEXT (B ACKGROUND: Rheumatic Heart disease is still a leading cause of valvular disease in developing countries like India and constitutes 10 to 50% of the cardiac patients in Indian hospitals. Echocardiography is a very sensitive investigation for the diagnosis of Rheumatic Carditis and its sequalae like Mitral, Aortic and Tricuspid valve disease as well as sub clinical Carditis. AIMS & OBJECTIVES: To study the profile, severity and gender based differences of valvular lesions on the Trans Thoracic Echocardiographic records of children diagnosed as Acute Rheumatic fever/ Rheumatic Heart disease. MATERIALS & METHODS: This study was conducted during D ecember’2014 by reviewing the records of trans thoracic Echocardiographic reports of our 36 cases (childhood Acute Rheumatic fever/ Rheumatic Heart disease cases for type and degree of valvular involvement according to AHA guidelines. RESULTS: Mitral valv e was involved most often (23 cases – 63.89%. Severe Mitral regurgitation is the common type of valvular lesions both in Boys and Girls (19.44% and 25% respectively. Isolated Aortic valve/ Tricuspid valve involvement was not found in our study. Mixed les ions were seen most often than pure isolated valvular lesions. CONCLUSION: Mitral valve was most commonly affected, while Regurgitant lesions were more common than Stenotic lesions and most severe in children less than 15 years age group. Aortic Regurgitat ion (AR was found more commonly in Girls than Boys in our study. But all these cases of AR had some other valvular involvement as Mixed lesions. Therefore Echocardiography should be done routinely for patients with Rheumatic Heart Disease, focusing on you nger population to facilitate diagnosis and definitive treatment before complications set in.

    ObjectiveTo validate a modified HEART [History, Electrocardiograph (ECG), Age, Risk factors and Troponin] risk score in chest pain patients with suspected non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in the emergency department (ED).Methods This retrospective cohort study used a prospectively acquired database and chest pain patients admitted to the emergency department with suspected NSTE-ACS were enrolled. Data recorded on arrival at the ED were used. The serum sample of high-sensitivity cardiac Troponin I other than conventional cardiac Troponin I used in the HEART risk score was tested. The modified HEART risk score was calculated. The end point was the occurrence of major adverse cardiac events (MACE) defined as a composite of acute myocardial infarction (AMI), percu-taneous intervention (PCI), coronary artery bypass graft (CABG), or all-cause death, within three months after initial presentation.Results A total of 1,300 patients were enrolled. A total of 606 patients (46.6%) had a MACE within three months: 205 patients (15.8%) were diag-nosed with AMI, 465 patients (35.8%) underwent PCI, and 119 patients (9.2%) underwent CABG. There were 10 (0.8%) deaths. A progres-sive, significant pattern of increasing event rate was observed as the score increased (P < 0.001 byχ2 for trend). The area under the receiver operating characteristic curve was 0.84. All patients were classified into three groups: low risk (score 0–2), intermediate risk (score 3–4), and high risk (score 5–10). Event rates were 1.1%, 18.5%, and 67.0%, respectively (P < 0.001).ConclusionsThe modified HEART risk score was validated in chest pain patients with suspected NSTE-ACS and may complement MACE risk assessment and patients triage in the ED. A prospective study of the score is warranted.

Lo encontrado debe auxiliar a identificar los pacientes con mayor riesgo de descompensación de la IC, y así, proyectar e imple-mentar intervenciones específicas que tengan como objetivo la reducción de las hospitalizaciones por IC.This study had the purpose to identify the sociodemographic and clinical profiles, history of hospitalizations due to Heart Failure (HF and follow-ups (regular appointments, drug treatment, facilities and difficulties for follow-up of patients admitted for clinical decompensation. Interviews were held with 61 patients, with average age of 58.1 (± 15.9 years, 3.5 (± 4.4 years of education and individual income of 1.3 (± 2.4 times the minimum wage. Most subjects were in functional classes III or IV of the New York Heart Association, having signs and symptoms of the congestive form of HF as the most frequent cause of hospitalization. Of all subjects, 75.4% reported clinical follow-ups, although they tended to be irregular. The use of drug therapy occurred in lower ratios than that recommended in the literature. The findings must help to identify patients with higher risk of HC decompensation, and, as such, design and implement specific interventions aiming at reducing re-admittances due to HF.

In chronic heart failure, incomplete intake of prescribed drugs (medication non-adherence is inversely associated with clinical prognosis. Therefore, we assessed medication knowledge in a cohort of patients with decompensated heart failure at hospital admission and after discharge in a prospective, cross-sectional study.Methods: One hundred and eleven patients presenting at the emergency department with acute decompensated heart failure were included (mean age 78.4±9.2, 59% men in the study. Patients’ medication knowledge was assessed during individual interviews at baseline, course of hospitalization, and 3 months after discharge. Individual responses were compared with the medical records of the referring general practitioner.Results: Median N-terminal prohormone of brain natriuretic peptide plasma concentration in the overall population at baseline was 4,208 pg/mL (2,023–7,101 pg/mL [interquartile range], 20 patients died between the second and third interview. The number of prescribed drugs increased from 8±3 at baseline to 9±3 after 3 months. The majority of patients did not know the correct number of their drugs. Medication knowledge decreased continuously from baseline to the third interview. At baseline, 37% (n=41 of patients stated the correct number of drugs to be taken, whereas only 18% (n=16 knew the correct number 3 months after discharge (P=0.008.

    Although macrocytic anemia can develop in patients with acute blood loss, such anemia in very old patients is uncommon. In this report, we describe the course of an 89-year-old woman who had a rapid recovery from macrocytic anemia by medication only after acute blood loss due to a gastric ulcer. She had been treated with antihypertensive drugs for the previous 28 years at our outpatient clinic, and was admitted because of acute anemia 6 days after she had experienced tarry stool. Her hemoglobin (Hb) count and mean corpuscular volume (MCV) were 8.4 g/dl, and 103 fl, respectively. A gastroscopic examination indicated that the tarry stool originated from a fresh gastric ulcer. She was treated with an iron preparation, a diuretic and a proton pump inhibitor. The anemia was rapidly improved to Hb 10.5 g/dl and MCV 106 fl in one week, and to Hb 14.5 g/dl and MCV 99 fl in 4 weeks. At admission, she had slight pleural effusion and slight edema associated with an increase in her plasma brain natriuretic peptide (BNP) level (323 pg/ml), and her left ventricular ejection fraction was 76% based on the echocardiography findings, which are signs of the high-output heart failure without remarkable left ventricular diastolic dysfunction (E/e': 11.2). However, these signs improved rapidly, and her BNP level thereafter decreased to 114 pg/ml within four weeks.

    Full Text Available Background: Heart failure (HF is one of the leading causes of hospitalization in adults in Brazil. However, most of the available data is limited to unicenter registries. The BREATHE registry is the first to include a large sample of hospitalized patients with decompensated HF from different regions in Brazil. Objective: Describe the clinical characteristics, treatment and prognosis of hospitalized patients admitted with acute HF. Methods: Observational registry study with longitudinal follow-up. The eligibility criteria included patients older than 18 years with a definitive diagnosis of HF, admitted to public or private hospitals. Assessed outcomes included the causes of decompensation, use of medications, care quality indicators, hemodynamic profile and intrahospital events. Results: A total of 1,263 patients (64±16 years, 60% women were included from 51 centers from different regions in Brazil. The most common comorbidities were hypertension (70.8%, dyslipidemia (36.7% and diabetes (34%. Around 40% of the patients had normal left ventricular systolic function and most were admitted with a wet-warm clinical-hemodynamic profile. Vasodilators and intravenous inotropes were used in less than 15% of the studied cohort. Care quality indicators based on hospital discharge recommendations were reached in less than 65% of the patients. Intrahospital mortality affected 12.6% of all patients included. Conclusion: The BREATHE study demonstrated the high intrahospital mortality of patients admitted with acute HF in Brazil, in addition to the low rate of prescription of drugs based on evidence.

  8. Pivotal importance of STAT3 in protecting the heart from acute and chronic stress: new advancement and unresolved issues

    Full Text Available The transcription factor Signal Transducer and Activator of Transcription 3 (STAT3 has been implicated in protecting the heart from acute ischemic injury under both basal conditions and as a crucial component of pre- and post-conditioning protocols. A number of anti-oxidant and antiapoptotic genes are upregulated by STAT3 via canonical means involving phosphorylation on Y705 and S727, although other incompletely defined posttranslational modifications are involved. In addition, STAT3 is now known to be present in cardiac mitochondria and to exert actions that regulate the electron transport chain, reactive oxygen species (ROS production, and mitochondrial permeability transition pore (mPTP opening. These non-canonical actions of STAT3 are enhanced by S727 phosphorylation. The molecular basis for the mitochondrial actions of STAT3 are poorly understood, but STAT3 is known to interact with a critical subunit of complex I and to regulate complex I function. Dysfunctional complex I has been implicated in ischemic injury, heart failure, and the aging process. Evidence also indicates that STAT3 is protective to the heart under chronic stress conditions, including hypertension, pregnancy, and advanced age. Paradoxically, the accumulation of unphosphorylated STAT3 (U-STAT3 in the nucleus has been suggested to drive pathological cardiac hypertrophy and inflammation via noncanonical gene expression, perhaps involving a distinct acetylation profile. U-STAT3 may also regulate chromatin stability. Our understanding of how the noncanonical genomic and mitochondrial actions of STAT3 in the heart are regulated and coordinated with the canonical actions of STAT3 is rudimentary. Here we present an overview of what is currently known about the pleotropic actions of STAT3 in the heart in order to highlight controversies and unresolved issues.

    Full Text Available INTRODUCTION: Obstructive Sleep Apnea (OSA is a major risk factor for cardiovascular disease. The goal of this study was to demonstrate whether the use of CPAP produces significant changes in the heart rate or in the heart rate variability of patients with OSA in the first night of treatment and whether gender and obesity play a role in these differences. METHODS: Single-center transversal study including patients with severe OSA corrected with CPAP. Only patients with total correction after CPAP were included. Patients underwent two sleep studies on consecutive nights: the first night a basal study, and the second with CPAP. We also analyzed the heart rate changes and their relationship with CPAP treatment, sleep stages, sex and body mass index. Twenty-minute segments of the ECG were selected from the sleep periods of REM, no-REM and awake. Heart rate (HR and heart rate variability (HRV were studied by comparing the R-R interval in the different conditions. We also compared samples from the basal study and CPAP nights. RESULTS: 39 patients (15 females, 24 males were studied. The mean age was 50.67 years old, the mean AHI was 48.54, and mean body mass index was 33.41 kg/m(2 (31.83 males, 35.95 females. Our results showed that HRV (SDNN decreased after the use of CPAP during the first night of treatment, especially in non-REM sleep. Gender and obesity did not have any influence on our results. CONCLUSIONS: These findings support that cardiac variability improves as an acute effect, independently of gender or weight, in the first night of CPAP use in severe OSA patients, supporting the idea of continuous use and emphasizing that noncompliance of CPAP treatment should be avoided even if it is just once.

Background: Patients with ACS are at risk for both cardiac autonomic dysfunction and clinical depression. Both conditions can negatively impact the ability to recover from an acute physiological insult, such as unstable angina or myocardial infarction, increasing the risk for adverse cardiovascular outcomes. HRV is recognized as a reflection of autonomic function. Methods: A narrative review was undertaken to evaluate state-of-the-art clinical research, using the PubMed database, January 2013. The search terms “heart rate variability” and “depression” were used in conjunction with “acute coronary syndrome”, “unstable angina”, or “myocardial infarction” to find clinical studies published within the past 10 years related to HRV and clinical depression, in patients with an ACS episode. Studies were included if HRV measurement and depression screening were undertaken during an ACS hospitalization or within 2 months of hospital discharge. Results: Nine clinical studies met the inclusion criteria. The

    Pulmonary hypertension in heart failure is associated with exercise intolerance and adverse outcomes. With the availability of multiple drugs that cause pulmonary vasodilation and decrease pulmonary arterial pressure, pulmonary hypertension becomes an attractive therapeutic target. Out of several classes of medications, oral phosphodiesterase inhibitors emerge as the most promising in terms of symptomatic improvement, hemodynamic benefits, reverse cardiac remodeling, and functional capacity. Future trials will show whether the use of these drugs translates to decreased morbidity and mortality in heart failure.

    Ivabradine, a bradycardic agent, has been shown to stably reduce patient's heart rate (HR) in the setting of acute cardiac care. However, an association between atrial fibrillation (AF) risk and acute ivabradine treatment remains a controversial clinical issue, and has not been thoroughly investigated. Bradycardia and abnormal atrial refractoriness induced by ivabradine treatment may enhance vulnerability to AF induction, especially when vagal nerve is concurrently activated. We aimed to experimentally investigate the effects of acute ivabradine treatment with/without concurrent vagal activation on AF inducibility. In 16 anesthetized dogs, cervical vagal nerves were prepared for electrical stimulation (VS). AF induction rate (AFIR) was determined by atrial burst pacing. HR, atrial action potential duration (APD), atrial effective refractory period (ERP), and AFIR were obtained consecutively at baseline, during delivery of VS (VS alone), after intravenous injection of ivabradine 0.5 mg/kg (n = 8, ivabradine group) or saline (n = 8, saline group), and again during VS delivery (drug+VS). In the ivabradine group, ivabradine alone significantly lowered HR compared to baseline, while ivabradine+VS significantly lowered HR compared to VS alone. Contrary to expectations, there were no significant differences in trends of APD, temporal dispersion of APD, ERP, and AFIR between ivabradine and saline groups. Irrespective of whether ivabradine or saline was injected, VS significantly shortened APD and ERP, and increased AFIR. Interestingly, although bradycardia in response to ivabradine injection was more intense than that to VS alone, AFIR was significantly lower after ivabradine injection than during VS alone. We conclude that, despite its intense bradycardic effect, acute ivabradine treatment does not increase AF inducibility irrespective of underlying vagal activity. This study may constitute support for the safety of using ivabradine in the setting of acute cardiac

    The most common use of inotropes is among hospitalized patients with acute decompensated heart failure, with reduced left ventricular ejection fraction and with signs of end-organ dysfunction in the setting of a low cardiac output. Inotropes can be used in patients with severe systolic heart failure awaiting heart transplant to maintain hemodynamic stability or as a bridge to decision. In cases where patients are unable to be weaned off inotropes, these agents can be used until a definite or escalated supportive therapy is planned, which can include coronary revascularization or mechanical circulatory support (intra-aortic balloon pump, extracorporeal membrane oxygenation, impella, left ventricular assist device, etc.). Use of inotropic drugs is associated with risks and adverse events. This review will discuss the use of the inotropes digoxin, dopamine, dobutamine, norepinephrine, milrinone, levosimendan, and omecamtiv mecarbil. Long-term inotropic therapy should be offered in selected patients. A detailed conversation with the patient and family shall be held, including a discussion on the risks and benefits of use of inotropes. Chronic heart failure patients awaiting heart transplants are candidates for intravenous inotropic support until the donor heart becomes available. This helps to maintain hemodynamic stability and keep the fluid status and pulmonary pressures optimized prior to the surgery. On the other hand, in patients with severe heart failure who are not candidates for advanced heart failure therapies, such as transplant and mechanical circulatory support, inotropic agents can be used for palliative therapy. Inotropes can help reduce frequency of hospitalizations and improve symptoms in these patients.

    The prognosis of decompensated cirrhosis resulting from chronic hepatitis B is poor, and the benefits of treatment with interferon are outweighed by serious side effects and by the risk of fatal exacerbation of disease activity. Lamivudine rapidly reduces hepatitis B virus (HBV)-DNA in serum to undetectable levels. We have treated 35 patients with chronic hepatitis B and decompensated cirrhosis with lamivudine 100 mg or 150 mg orally once daily. Pretreatment, all were positive for HBV-DNA in serum. Ten had Child-Pugh class B and 25 had Child-Pugh class C liver disease. Seven patients underwent liver transplantation within 6 months of treatment initiation, 5 patients died within 6 months, and 23 patients were treated for at least 6 months (mean = 19 months). In a majority of these 23 cases, there was a slow but marked improvement in liver function, which was most apparent after 9 months of treatment, with a decrease in serum bilirubin from 67 +/- 13 to 30 +/- 4 micromol/L (P decompensated HBV cirrhosis, but the long-term benefits remain uncertain.

We investigated turbulence onset (TO and turbulence slope (TS values among patients with acute ST-elevation myocardial infarction (STEMI underwent revascularization by means of primary PCI or fibrinolytic. We hypothesized that the values of TO and TS were different in two kinds of revascularization treatment. The subjects underwent 24 hours ECG recording after revascularization therapy. TO was quantified by the relative change of the first two sinus RR intervals following a ventricular premature beat (VPB and the last two sinus RR intervals before the VPB. TS was quantified by the maximum positive slope of a regression line assessed over any sequence of five subsequent sinus rhythm RR intervals within the first two sinus rhythm intervals after a VPB. Thirteen patients (mean of age 56 ± 9 years old who underwent revascularization treatment of acute STEMI were eligible as subject of this study.Ten patients underwent fibrinolytic therapy and three patients underwent primary PCI. TO value was significantly different between PCI group and fibrinolytic group (-3.3 ± 1.7 % vs -0.2 ± 0.9 % ; P=0.03. The Primary PCI group has better outcome on turbulence slope value (TS than fibrinolytic group but not significance (7.7 ± 4.4 msec/RR interval vs 3.4 ± 2.6 msec/RR interval; P = 0.056. In conclusion, TO was better in acute STEMI patient undergone PCI compare to that undergone fibrinolytic therapy.

  1. Neurogenic stunned myocardium - do we consider this diagnosis in patients with acute central nervous system injury and acute heart failure?

    Neurogenic stunned myocardium (NSM) is defined as myocardial injury and dysfunction of a sudden onset, occurring after various types of acute brain injury as a result of an imbalance in the autonomic nervous system. The typical spectrum of clinically observed abnormalities includes acute left ventricular failure, not uncommonly progressing to cardiogenic shock with hypotension that requires inotropic agents, pulmonary oedema and various arrhythmias. Commonly-seen electrocardiographic changes include: prolonged QT interval, ST segment changes, T-wave inversion, a new Q-wave or U-wave. Echocardiography shows both an impaired both systolic and diastolic function of the left ventricle. Biochemical markers of NSM comprise metabolic acidosis and increased cardiac enzymes and markers: creatine kinase (CK), and CK-MB, troponin I and B-type natriuretic peptide. The main cause of NSM is myocardial injury induced by local catecholamine release from nerve endings within the myocardium. Recently, a theory has been proposed to classify NSM as one of the stress-related cardiomyopathies, together with Takotsubo cardiomyopathy, acute left ventricular failure in the critically ill, cardiomyopathy associated with pheochromacytoma and exogenous catecholamine administration. The occurrence of NSM increases the risk of life-threatening complications, death, and worsens neurologic outcome. As far as we know, treatment should generally focus on the underlying neurologic process in order to maximize neurologic recovery. Improvement in neurologic pathology leads to rapid improvement in cardiac function and its full recovery, as NSM is a fully reversible condition if the patient survives. Awareness of the existence of NSM and a deeper knowledge of its etiopathology may reduce diagnostic errors, optimise its treatment.

    AIM: To determine the predictors of 50 d in-hospital mortality in decompensated cirrhosis patients with spontaneous bacterial peritonitis(SBP).METHODS: Two hundred and eighteen patients admitted to an intensive care unit in a tertiary care hospital between June 2013 and June 2014 with the diagnosis of SBP(during hospitalization) and cirrhosis were retrospectively analysed. SBP was diagnosed by abdominal paracentesis in the presence of polymorphonuclear cell count ≥ 250 cells/mm3 in the peritoneal fluid. Student’s t test, multivariate logistic regression, cox proportional hazard ratio(HR), receiver operating characteristics(ROC) curves and Kaplan-Meier survival analysis were utilized for statistical analysis. Predictive abilities of several variables identified by multivariate analysis were compared using the area under ROC curve. P < 0.05 were considered statistical significant. RESULTS: The 50 d in-hospital mortality rate attributable to SBP is 43.11%(n = 94). Median survival duration for those who died was 9 d. In univariate analysis acute kidney injury(AKI), hepatic encephalopathy, septic shock, serum bilirubin, international normalized ratio, aspartate transaminase, and model for end-stage liver disease- sodium(MELD-Na) were significantly associated with in- hospital mortality in patients with SBP(P ≤ 0.001). Multivariate coxproportional regression analysis showed AKI(HR = 2.16, 95%CI: 1.36-3.42, P = 0.001) septic shock(HR = 1.73, 95%CI: 1.05-2.83, P = 0.029) MELD-Na(HR = 1.06, 95%CI: 1.02-1.09, P ≤ 0.001) was significantly associated with 50 d in-hospital mortality. The prognostic accuracy for AKI, MELD-Na and septic shock was 77%, 74% and 71% respectively associated with 50 d inhospital mortality in SBP patients.CONCLUSION: AKI, MELD-Na and septic shock were predictors of 50 d in-hospital mortality in decompensated cirrhosis patients with SBP.

    2014-01-01

    Background Depression is prevalent in coronary heart disease (CHD) patients and increases risk for acute coronary syndrome (ACS) recurrence and mortality despite optimal medical care. The pathways underlying this risk remain elusive. Psychological stress (PS) can provoke impairment in myocardial perfusion and trigger ACS. A confluence of acute PS with depression might reveal coronary vascular mechanisms of risk. We tested whether depression increased risk for impaired myocardial perfusion during acute PS among patients with stable CHD. Methods and Results Patients (N=146) completed the Beck Depression Inventory‐I (BDI‐I), a measure of depression linked to recurrent ACS and post‐ACS mortality, and underwent single‐photon emission computed tomography myocardial perfusion imaging at rest and during acute PS. The likelihood of new/worsening impairment in myocardial perfusion from baseline to PS as a function of depression severity was tested. On the BDI‐I, 41 patients scored in the normal range, 48 in the high normal range, and 57 in the depressed range previously linked to CHD prognosis. A BDI‐I score in the depressed range was associated with a significantly greater likelihood of new/worsening impairment in myocardial perfusion from baseline to PS (odds ratio =2.89, 95% CI: 1.26 to 6.63, P=0.012). This remained significant in models controlling ACS recurrence/mortality risk factors and medications. There was no effect for selective serotonin reuptake inhibitor medications. Conclusions Depressed patients with CHD are particularly susceptible to impairment in myocardial perfusion during PS. The confluence of PS with depression may contribute to a better understanding of the depression‐associated risk for ACS recurrence and mortality. PMID:25359402

    Primary prevention of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in children depends on prompt and effective diagnosis and treatment of pharyngitis at the primary level of care. Cost-effectiveness modeling shows that the most cost-effective strategy for primary prevention in South Africa (SA) is to use a simple symptomatic clinical decision rule (CDR) to diagnose pharyngitis in children presenting at the primary level of care and then to treat them with a single dose of intramuscular penicillin. Treat All and CDR2+ strategies are affordable and simple and miss few cases of streptococcal pharyngitis at the primary level of care. The CDR2+ strategy is the most cost-effective for primary prevention of ARF and RHD in urban SA and should complement primordial and secondary prevention efforts.

    Ischaemic heart disease and the heart failure that often results, remain the leading causes of death and disability in Europe and worldwide. As such, in order to prevent heart failure and improve clinical outcomes in patients presenting with an acute ST-segment elevation myocardial infarction and patients undergoing coronary artery bypass graft surgery, novel therapies are required to protect the heart against the detrimental effects of acute ischaemia/reperfusion injury. During the last three decades, a wide variety of ischaemic conditioning strategies and pharmacological treatments have been tested in the clinic - however, their translation from experimental to clinical studies for improving patient outcomes has been both challenging and disappointing. Therefore, in this Position Paper of the European Society of Cardiology Working Group on Cellular Biology of the Heart, we critically analyse the current state of ischaemic conditioning in both the experimental and clinical settings, provide recommendations for improving its translation into the clinical setting, and highlight novel therapeutic targets and new treatment strategies for reducing acute myocardial ischaemia/reperfusion injury.

  17. Aromatase inhibition attenuates desflurane-induced preconditioning against acute myocardial infarction in male mouse heart in vivo.

    Directory of Open Access Journals (Sweden)

    Virginija Jazbutyte

    Full Text Available The volatile anesthetic desflurane (DES effectively reduces cardiac infarct size following experimental ischemia/reperfusion injury in the mouse heart. We hypothesized that endogenous estrogens play a role as mediators of desflurane-induced preconditioning against myocardial infarction. In this study, we tested the hypothesis that desflurane effects local estrogen synthesis by modulating enzyme aromatase expression and activity in the mouse heart. Aromatase metabolizes testosterone to 17β- estradiol (E2 and thereby significantly contributes to local estrogen synthesis. We tested aromatase effects in acute myocardial infarction model in male mice. The animals were randomized and subjected to four groups which were pre-treated with the selective aromatase inhibitor anastrozole (A group and DES alone (DES group or in combination (A+DES group for 15 minutes prior to surgical intervention whereas the control group received 0.9% NaCl (CON group. All animals were subjected to 45 minutes ischemia following 180 minutes reperfusion. Anastrozole blocked DES induced preconditioning and increased infarct size compared to DES alone (37.94 ± 15.5% vs. 17.1 ± 3.62% without affecting area at risk and systemic hemodynamic parameters following ischemia/reperfusion. Protein localization studies revealed that aromatase was abundant in the murine cardiovascular system with the highest expression levels in endothelial and smooth muscle cells. Desflurane application at pharmacological concentrations efficiently upregulated aromatase expression in vivo and in vitro. We conclude that desflurane efficiently regulates aromatase expression and activity which might lead to increased local estrogen synthesis and thus preserve cellular integrity and reduce cardiac damage in an acute myocardial infarction model.

    2003-10-01

    The contribution of vanadate oligomers to the acute histological effects of vanadium was analyzed in the heart, kidney, and liver of Halobatrachus didactylus (Schneider, 1801). A sublethal vanadium dose (5 mM, 1 mL/kg) in the form of metavanadate (containing ortho and metameric species) or in the form of decavanadate (containing only decameric species) was intraperitoneally administered by injection, and specimens of H. didactylus were sacrificed at one and seven days postinjection. Sections of heart ventricle and renal and hepatic tissue were stained with hematoxylin-eosin and examined by light microscopy to identify vanadium-induced tissue injury. In addition, PicroSirius-stained ventricular sections were analyzed by bipolarized light microscopy to determine the fraction of myocardium occupied by the ventricular wall structural elements (collagen I, collagen III, and cardiac muscle). Both vanadate solutions produced similar effects in the renal tissue. Morphological alterations included damaged renal tubules showing disorganized epithelial cells in different states of necrosis. Reabsorbed renal tubules and hyperchromatic interstitial tissue were also observed. The hepatic tissue presented hyperchromatic and hypertrophied nuclei, along with necrotic and hypertrophied hepatocytes, and more severe changes were observed in the liver with exposure to decavanadate. Vanadate oligomers promoted evident tissue lesions in the kidney and liver, but not in the cardiac tissue. However, cardiac tissue structural changes were produced. For example, decavanadate induced a hypertrophy of the ventricle due to a decrease in the percentage of myocardium occupied by collagen fibers. In general, decavanadate was shown to be more toxic than metavanadate.

    β-Blockers (BBs) are an essential class of cardiovascular medications for reducing morbidity and mortality in patients with heart failure (HF). However, a large body of data indicates that BBs should not be used as first-line therapy for hypertension (HTN). Additionally, new data have questioned the role of BBs in the treatment of stable coronary heart disease (CHD). However, these trials mainly tested the non-vasodilating β1 selective BBs (atenolol and metoprolol) which are still the most commonly prescribed BBs in the USA. Newer generation BBs, such as the vasodilating BBs carvedilol and nebivolol, have been shown not only to be better tolerated than non-vasodilating BBs, but also these agents do not increase the risk of diabetes mellitus (DM), atherogenic dyslipidaemia or weight gain. Moreover, carvedilol has the most evidence for reducing morbidity and mortality in patients with HF and those who have experienced an acute myocardial infarction (AMI). This review discusses the cornerstone clinical trials that have tested BBs in the settings of HTN, HF and AMI. Large randomised trials in the settings of HTN, DM and stable CHD are still needed to establish the role of BBs in these diseases, as well as to determine whether vasodilating BBs are exempt from the disadvantages of non-vasodilating BBs.

  1. Taxol inhibits stretch-induced electrophysiological alterations in isolated rat hearts with acute myocardial infarction

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Mechanosensitive channels have been determined to work as transducers of mechanoelectric feedback in the heart, which is associated with the generation of arrhythmias. Recent studies have investigated the role of the cytoskeleton in ion channels control. This study explored the ability of taxol to inhibit stretch-induced electrophysiological alterations in the ischemic myocardium. Thirty-two Wistar rats were randomly divided into four groups: normal control group (n=9), taxol group (n=7), myocardial infarction (MI) group (n=9), and MI+taxol group (n=7). After Langendorff perfusion, the isolated hearts were stretched for 5 s by balloon inflation to 0.2 or 0.3 mL. The effects of stretching on 90% monophasic action potential duration (MAPD90), premature ventricular beats (PVB), and ventricular tachycardia (VT) were observed for 30 s. Stretching increased MAPD90 in both the normal control and MI groups, but MAPD90 increased more in the MI group for the same degree of stretch. Taxol (5 μmol L?1) had no effect on MAPD90 under baseline, unstretched conditions, but MAPD90 in the taxol group was slightly increased after stretching compared with the normal control group (P>0.05). However, taxol reduced MAPD90 in infarcted myocardium (P<0.05 at V=0.3 mL). The incidences of PVB and VT in the MI group were higher than in the normal control group (both P<0.01). Taxol had no effect on the occurrence of arrhythmias in normal myocardium, but it inhibited PVB and VT in infarcted hearts (both P<0.01). Thus changes in MAPD and the occurrence of arrhythmias caused by mechanical stretching of the myocardium could be inhibited by taxol in isolated rat hearts during AMI, indicating the involvement of tubulin in mechanoelectric feedback in AMI.

    The clinical course and medical treatment of patients with congestive heart failure (CHF) complicating acute myocardial infarction (AMI) are not well established, especially in patients with concomitant renal dysfunction. We performed a retrospective analysis of the prospective Korean Acute Myocardial Infarction Registry to assess the medical treatments and clinical outcomes of patients with CHF (Killip classes II or III) complicated by AMI, in the presence or absence of renal dysfunction. Of 13,498 patients with AMI, 2769 (20.5%) had CHF on admission. Compared to CHF patients with preserved renal function, in-hospital mortality and major adverse cardiac events were increased both at 1 month and at 1 year after discharge in patients with renal dysfunction (1154; 41.7%). Postdischarge use of aspirin, betablockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, or angiotensin II receptor blockers and statins significantly reduced the 1-year mortality rate for CHF patients with renal dysfunction; such reduction was not observed for those without renal dysfunction, except in the case of aspirin. Patients with CHF complicating AMI, which is accompanied by renal dysfunction, are at higher risk for adverse cardiovascular outcomes than patients without renal dysfunction. However, they receive fewer medications proven to reduce mortality rates.

    Perinatal exposure to infection is highly associated with adverse outcomes. Experimentally, acute, severe exposure to gram-negative bacterial lipopolysaccharide (LPS) is associated with increased fetal heart rate variability (FHRV). It is unknown whether FHRV is affected by subclinical infection with or without acute exacerbations. We therefore tested the hypothesis that FHRV would be associated with hypotension after acute on chronic exposure to LPS. Chronically instrumented fetal sheep at 0.7 gestation were exposed to a continuous low-dose LPS infusion (n = 12, 100 ng/kg over 24 h, followed by 250 ng·kg(-1)·24 h(-1) for a further 96 h) or the same volume of saline (n = 10). Boluses of either 1 μg LPS or saline were given at 48, 72, and 96 h. Low-dose infusion was not associated with hemodynamic or FHRV changes. The first LPS bolus was associated with tachycardia and suppression of nuchal electromyographic activity in all fetuses. Seven of twelve fetuses developed hypotension (a fall in mean arterial blood pressure ≥5 mmHg). FHRV was transiently increased only at the onset of hypotension, in association with increased cytokine induction and electroencephalogram suppression. FHRV then fell before the nadir of hypotension, with transient suppression of short-term FHRV. After the second LPS bolus, the hypotension group showed a biphasic pattern of a transient increase in FHRV followed by more prolonged suppression. These findings suggest that infection-related hypotension in the preterm fetus mediates the transient increase in FHRV and that repeated exposure to LPS leads to progressive loss of FHRV.

  8. beta2 adrenergic agonists in acute lung injury? The heart of the matter.

    2009-01-01

    Despite extensive research into its pathophysiology, acute lung injury/acute respiratory distress syndrome (ALI/ARDS) remains a devastating syndrome with mortality approaching 40%. Pharmacologic therapies that reduce the severity of lung injury in vivo and in vitro have not yet been translated to effective clinical treatment options, and innovative therapies are needed. Recently, the use of beta2 adrenergic agonists as potential therapy has gained considerable interest due to their ability to increase the resolution of pulmonary edema. However, the results of clinical trials of beta agonist therapy for ALI/ARDS have been conflicting in terms of benefit. In the previous issue of Critical Care, Briot and colleagues present evidence that may help clarify the inconsistent results. The authors demonstrate that, in oleic acid lung injury in dogs, the inotropic effect of beta agonists may recruit damaged pulmonary capillaries, leading to increased lung endothelial permeability.

    Full Text Available Abstract Background A major change has occurred in the last few years in the therapeutic approach to patients presenting with all forms of acute coronary syndromes. Whether or not these patients present initially to tertiary cardiac care centers, they are now routinely referred for early coronary angiography and increasingly undergo percutaneous revascularization. This practice is driven primarily by the angiographic image and technical feasibility. Concomitantly, there has been a decline in expectant or ischemia-guided medical management based on specific clinical presentation, response to initial treatment, and results of noninvasive stratification. This 'tertiarization' of acute coronary care has been fuelled by the increasing sophistication of the cardiac armamentarium, the peer-reviewed publication of clinical studies purporting to show the superiority of invasive cardiac interventions, and predominantly supporting (non-peer-reviewed editorials, newsletters, and opinion pieces. Discussion This review presents another perspective, based on a critical reexamination of the evidence. The topics addressed are: reperfusion treatment of ST-elevation myocardial infarction; the indications for invasive intervention following thrombolysis; the role of invasive management in non-ST-elevation myocardial infarction and unstable angina; and cost-effectiveness and real world considerations. A few cases encountered in recent practice in community and tertiary hospitals are presented for illustrative purposes The numerous and far-reaching scientific, economic, and philosophical implications that are a consequence of this marked change in clinical practice as well as healthcare, decisional and conflict of interest issues are explored. Summary The weight of evidence does not support the contemporary unfocused broad use of invasive interventional procedures across the spectrum of acute coronary clinical presentations.

  13. Morphine in the treatment of acute pulmonary oedema--Why?

    Science.gov (United States)

    Ellingsrud, C; Agewall, S

    2016-01-01

    Morphine has for a long time, been used in patients with acute pulmonary oedema due to its anticipated anxiolytic and vasodilatory properties, however a discussion about the benefits and risks has been raised recently. A literature search in Medline and Embase using the keywords "pulmonary oedema" OR "lung oedema" OR "acute heart failure" AND "morphine" was performed. A certain vasodilation has been described after morphine administration, but the evidence for this mechanism is relatively poor and morphine-induced anxiolysis may possibly be the most important factor of morphine in pulmonary oedema and therefore some authors have suggested benzodiazepines as an alternative treatment. Respiratory depression seems to be a less relevant clinical problem according to the literature, whereas vomiting is common, which may cause aspiration. In the largest outcome study, based on the ADHERE registry, morphine given in acute decompensated heart failure was an independent predictor of increased hospital mortality, with an odds ratio of 4.8 (95% CI: 4.52-5.18, pmorphine administration and mortality, which was lost after adjusting for confounding factors. Morphine is still used for pulmonary oedema in spite of poor scientific background data. A randomised, controlled study is necessary in order to determine the effect--and especially the risk--when using morphine for pulmonary oedema. Since the positive effects are not sufficiently documented, and since the risk for increased mortality cannot be ruled out, one can advocate that the use should be avoided.

    Decompensated liver cirrhosis (LC), a life-threatening complication of chronic liver disease, is one of the major indications for liver transplantation. Recently, mesenchymal stem cell (MSC) transfusion has been shown to lead to the regression of liver fibrosis in mice and humans. This study examined the safety and efficacy of umbilical cord-derived MSC (UC-MSC) in patients with decompensated LC. A total of 45 chronic hepatitis B patients with decompensated LC, including 30 patients receiving UC-MSC transfusion, and 15 patients receiving saline as the control, were recruited; clinical parameters were detected during a 1-year follow-up period. No significant side-effects and complications were observed in either group. There was a significant reduction in the volume of ascites in patients treated with UC-MSC transfusion compared with controls (P decompensated LC. UC-MSC transfusion, therefore, might present a novel therapeutic approach for patients with decompensated LC.

    A 30-year-old man had multiple pellet injuries after being shot. An asymptomatic, acute, inferior-wall myocardial infarction was detected on an electrocardiogram at the time of a pre-anesthetic evaluation for eye surgery. A computed tomographic scan of the chest confirmed the presence of an intracardiac foreign body. Coronary angiography showed occlusion of the distal right coronary artery by a pellet. The patient was managed conservatively with aspirin and metoprolol. In conclusion, a single coronary lesion, the absence of other cardiac complications, and a favorable outcome with conservative medical treatment after a gunshot injury contribute to the rarity of this case of myocardial infarction.

    Twenty patients who had undergone a heterotopic heart transplant were studied prospectively to determine the relationship between rejection and ventricular dysfunction assessed from gated blood pool studies. A fully automated method for detecting ventricular edges was implemented; its success rate for the grafted left and right ventricles was 94% and 77%, respectively. The parameters, peak ejection and filling rates, were calculated pixel per pixel using a two-harmonic Fourier algorithm and then averaged over the ventricular region of interest. Peak filling and ejection rates were closely related with the severity of the rejection, while the left ventricular ejection fraction was not. Peak filling rates of both ventricles were the indices closely related to the presence of moderate rejection. Despite the low number of patients, these data suggested that gated blood pool derived indices of ventricular function are associated with ventricular dysfunction resulting from myocarditis rejection. Radionuclide ventriculography provides parametric data which are accurate and reliable for the diagnosis of rejection. (orig.).

    Confusion and controversy exist regarding the cardiovascular effects of dietary supplements containing caffeine and Citrus aurantium (bitter orange) extract. The primary protoalkaloidal ingredient in bitter orange extract is p-synephrine which has some structural similarities to ephedrine and nor-epinehrine, but exhibits markedly different pharmacokinetic and receptor binding properties. The goal of this study was to investigate the cardiovascular effects of a product containing caffeine, bitter orange extract (p-synephrine) and green tea extract in mildly overweight individuals. Fourteen female and nine male subjects (age 24.7 ±7.4 yrs, BMI: 26.6 ±3.8) volunteered in this randomized, placebo-controlled, crossover, double-blind designed study. On day one, subjects entered the laboratory following an overnight fast. Heart rate and blood pressure were recorded at 60 min. Expired air was analyzed for the next 10 min of the session. At each of three meals, subjects ingested one capsule that was either a non-caloric placebo or a dietary supplement that contained 13 mg p-synephrine and 176 mg caffeine. On the following day, the subjects returned and repeated the protocol for data collection beginning 60 min after consuming one capsule of the placebo or the dietary supplement. No effects of the dietary supplement on heart rate, systolic and diastolic blood pressure or mean arterial pressure were observed. No between or within group differences were observed when data were analyzed for gender and caffeine usage. A small but significant decrease in resting respiratory exchange ratio was observed for the low caffeine user group in response to the product containing caffeine and p-synephrine. The results of this study indicate that ingestion of a product containing bitter orange extract, caffeine and green tea extract does not lead to increased cardiovascular stress and that fat oxidation may increase in certain populations.

    BACKGROUND. Pulmonary hypertension (PH) is associated with poor outcomes, yet specific treatments only exist for a small subset of patients. The most common form of PH is that associated with left heart disease (Group 2), for which there is no approved therapy. Nitrite has shown efficacy in preclinical animal models of Group 1 and 2 PH, as well as in patients with left heart failure with preserved ejection fraction (HFpEF). We evaluated the safety and efficacy of a potentially novel inhaled formulation of nitrite in PH-HFpEF patients as compared with Group 1 and 3 PH. METHODS. Cardiopulmonary hemodynamics were recorded after acute administration of inhaled nitrite at 2 doses, 45 and 90 mg. Safety endpoints included change in systemic blood pressure and methemoglobin levels. Responses were also compared with those administered inhaled nitric oxide. RESULTS. Thirty-six patients were enrolled (10 PH-HFpEF, 20 Group 1 pulmonary arterial hypertension patients on background PH-specific therapy, and 6 Group 3 PH). Drug administration was well tolerated. Nitrite inhalation significantly lowered pulmonary, right atrial, and pulmonary capillary wedge pressures, most pronounced in patients with PH-HFpEF. There was a modest decrease in cardiac output and systemic blood pressure. Pulmonary vascular resistance decreased only in Group 3 PH patients. There was substantial increase in pulmonary artery compliance, most pronounced in patients with PH-HFpEF. CONCLUSIONS. Inhaled nitrite is safe in PH patients and may be efficacious in PH-HFpEF and Group 3 PH primarily via improvements in left and right ventricular filling pressures and pulmonary artery compliance. The lack of change in pulmonary vascular resistance likely may limit efficacy for Group 1 patients. TRIAL REGISTRATION. ClinicalTrials.gov NCT01431313 FUNDING.

    Although historically the intra-aortic balloon pump has been the only mechanical circulatory support device available to clinicians, a number of new devices have become commercially available and have entered clinical practice. These include axial flow pumps, such as Impella®; left atrial to femoral artery bypass pumps, specifically the TandemHeart; and new devices for institution of extracorporeal membrane oxygenation. These devices differ significantly in their hemodynamic effects, insertion, monitoring, and clinical applicability. This document reviews the physiologic impact on the circulation of these devices and their use in specific clinical situations. These situations include patients undergoing high-risk percutaneous coronary intervention, those presenting with cardiogenic shock, and acute decompensated heart failure. Specialized uses for right-sided support and in pediatric populations are discussed and the clinical utility of mechanical circulatory support devices is reviewed, as are the American College of Cardiology/American Heart Association clinical practice guidelines.

    Advanced hemodynamic monitoring is a critical component of treatment in clinical situations where aggressive yet guided hemodynamic interventions are required in order to stabilize the patient and optimize outcomes. While there are many tools at a physician's disposal to monitor patients in a hospital setting, the reality is that none of these tools allow hi-fidelity assessment or continuous monitoring towards early detection of hemodynamic instability. We present an advanced automated analytical system which would act as a continuous monitoring and early warning mechanism that can indicate pending decompensation before traditional metrics can identify any clinical abnormality. This system computes novel features or bio-markers from both heart rate variability (HRV) as well as the morphology of the electrocardiogram (ECG). To compare their effectiveness, these features are compared with the standard HRV based bio-markers which are commonly used for hemodynamic assessment. This study utilized a unique database containing ECG waveforms from healthy volunteer subjects who underwent simulated hypovolemia under controlled experimental settings. A support vector machine was utilized to develop a model which predicts the stability or instability of the subjects. Results showed that the proposed novel set of features outperforms the traditional HRV features in predicting hemodynamic instability.

    Microcannular liposuction in tumescent anesthesia is the most effective treatment for painful lipedema. Tumescent anesthesia is an established and safe procedure in local analgesia when performed according to guidelines. Major adverse effects are rare. In patients with advanced lipedema, however, the commonly presented comorbidities bear additional risks.We report on post-surgical acute pulmonary edema after tumescent liposuction according to guidelines in a 52-year-old female patient with lipedema of the legs. We discuss in detail possible scenarios that might be involved in such emergency. In the present case the most likely was a retarded community acquired atypical pneumonia with aggravation of pre-existent comorbidities.A combined treatment with intravenous b-lactam antibiosis, positive pressure ventilation, and continuous venovenous hemodialysis and filtration resulted in complete remission in a couple of days. In conclusion, tumescent liposuction of advanced lipedema patients should only be performed in well-trained centers with sufficient infrastructure.

    Renal failure is common in heart failure due to renovascular constriction and hypotension. We tested whether selective pharmacological renal artery vasodilation and active renal artery perfusion (ARP) could improve renal function without adverse effects on systemic blood pressure in a canine model of acute heart failure (AHF). AHF was induced by coronary microembolization in 16 adult mongrel dogs. In five dogs, selective intrarenal (IR) papaverine (1, 2, and 4 mg/min) was administered into the left renal artery. In six dogs, ARP was performed in the left renal artery to normalize mean renal arterial pressure followed by administration of IR papaverine (2 mg/min). In five dogs, ARP plus intravenous furosemide was tested. Urine output (UO) and cortical renal blood flow decreased during AHF and were restored by 2 mg/min IR papaverine (UO: baseline 4.2 +/- 0.6, AHF 1.6 +/- 1.3, IR papaverine 5.8 +/- 1.1 ml/15 min; cortical blood flow: baseline 4.3 +/- 0.2, AHF 2.4 +/- 0.6, IR papaverine 4.2 +/- 1.2 ml/min/g) with no significant change in aortic pressure. ARP also increased urine output and cortical renal blood flow (UO: baseline 5.0 +/- 1.1, AHF 0.5 +/- 0.4, ARP 3.8 +/- 3.1 ml/15 min; cortical blood flow: baseline 4.0 +/- 0.5, AHF 2.0 +/- 0.8, ARP 3.52 +/- 1.1 ml/min/g). A combination of these methods in AHF further increased urine output to twice the normal baseline (10.5 +/- 7.5 ml/15 min). Addition of furosemide synergistically increased UO above that achieved with ARP alone (5.5 +/- 2.6 versus 40.3 +/- 24.7 ml/15 min, p = 0.03). In conclusion, ARP and selective renal vasodilation may effectively promote salt and water excretion in the setting of heart failure, particularly when systemic blood pressure is low.

    A workshop was organized by the Agenzia Italiana del Farmaco (AIFA) to discuss unmet needs and ways forward in the development of medicines in heart failure, their rationale, and cost-effective use. An integrated, multidisciplinary approach, including patients' needs and perspectives, was advocated by all the participants as the way to the most effective treatment regimens. More work is needed for reaching consensus on clinical and functional endpoints, for validating patient reported outcomes and measurements of well-being. Similarly, the integration into the clinical programmes of the health technology assessment/payers perspective, in particular, the evaluation of 'real-life' treatment effectiveness and of health as a value, would help in shifting the development and authorization of medicines from the molecule paradigm to their evaluation in the context of the whole health care regimen. Through this kind of workshop, AIFA is trying to build a template for meetings devoted to debate unmet needs with all stakeholders towards tentative road maps for the future.

    Renal dysfunction is a frequent finding in patients with acute heart failure (AHF) and an important prognostic factor for adverse outcomes. Worsening of renal function occurs in 30-50% of patients hospitalised for AHF, and is associated with increased mortality, prolonged hospital stay and increased risk of readmission. Likely mechanisms involved in the decrease in renal function include impaired haemodynamics and activation of neurohormonal factors, such as the renin-angiotensin-aldosterone system, the sympathetic nervous system and the arginine-vasopressin system. Additionally, many drugs currently used to treat AHF have a detrimental effect on renal function. Therefore, pharmacotherapy for AHF should carefully take into account any potential complications related to renal function. Serelaxin, currently in clinical development for the treatment of AHF is a recombinant form of human relaxin-2, identical in structure to the naturally occurring human relaxin-2 peptide hormone that mediates cardiac and renal adaptations during pregnancy. Data from both pre-clinical and clinical studies indicate a potentially beneficial effect of serelaxin on kidney function. In this review, we discuss the mechanisms and impact of impairment of renal function in AHF, and the potential benefits of new therapies, such as serelaxin, in this context.

    Chronic stress detection is an important factor in predicting and reducing the risk of cardiovascular disease. This work is a pilot study with a focus on developing a method for detecting short-term psychophysiological changes through heart rate variability (HRV) features. The purpose of this pilot study is to establish and to gain insight on a set of features that could be used to detect psychophysiological changes that occur during chronic stress. This study elicited four different types of arousal by images, sounds, mental tasks and rest, and classified them using linear and non-linear HRV features from electrocardiograms (ECG) acquired by the wireless wearable ePatch® recorder. The highest recognition rates were acquired for the neutral stage (90%), the acute stress stage (80%) and the baseline stage (80%) by sample entropy, detrended fluctuation analysis and normalized high frequency features. Standardizing non-linear HRV features for each subject was found to be an important factor for the improvement of the classification results.

    Comparing the diagnostic value of multi-sequential cardiac magnetic resonance imaging (CMR) with endomyocardial biopsy (EMB) for sub-clinical cardiac allograft rejection. One hundred and forty-six examinations in 73 patients (mean age 53 ± 12 years, 58 men) were performed using a 1.5 Tesla system and compared to EMB. Examinations included a STIR (short tau inversion recovery) sequence for calculation of edema ratio (ER), a T1-weighted spin-echo sequence for assessment of global relative enhancement (gRE), and inversion-recovery sequences to visualize late gadolinium enhancement (LGE). Histological grade ≥1B was considered relevant rejection. One hundred and twenty-seven (127/146 = 87 %) EMBs demonstrated no or mild signs of rejection (grades ≤1A) and 19/146 (13 %) a relevant rejection (grade ≥1B). Sensitivity, specificity, positive predictive, and negative predictive values were as follows: ER: 63 %, 78 %, 30 %, and 93 %; gRE: 63 %, 70 %, 24 %, and 93 %; LGE: 68 %, 36 %, 13 %, and 87 %; with the combination of ER and gRE with at least one out of two positive: 84 %, 57 %, 23 %, and 96 %. ROC analysis revealed an area under the curve of 0.724 for ER and 0.659 for gRE. CMR parameters for myocarditis are useful to detect sub-clinical acute cellular rejection after heart transplantation. Comparable results to myocarditis can be achieved with a combination of parameters. (orig.)

    Acute right ventricular (RV) failure is a complex clinical syndrome that results from many causes. Research efforts have disproportionately focused on the failing left ventricle, but recently the need has been recognized to achieve a more comprehensive understanding of RV anatomy, physiology, and pathophysiology, and of management approaches. Right ventricular mechanics and function are altered in the setting of either pressure overload or volume overload. Failure may also result from a primary reduction of myocardial contractility owing to ischaemia, cardiomyopathy, or arrhythmia. Dysfunction leads to impaired RV filling and increased right atrial pressures. As dysfunction progresses to overt RV failure, the RV chamber becomes more spherical and tricuspid regurgitation is aggravated, a cascade leading to increasing venous congestion. Ventricular interdependence results in impaired left ventricular filling, a decrease in left ventricular stroke volume, and ultimately low cardiac output and cardiogenic shock. Identification and treatment of the underlying cause of RV failure, such as acute pulmonary embolism, acute respiratory distress syndrome, acute decompensation of chronic pulmonary hypertension, RV infarction, or arrhythmia, is the primary management strategy. Judicious fluid management, use of inotropes and vasopressors, assist devices, and a strategy focusing on RV protection for mechanical ventilation if required all play a role in the clinical care of these patients. Future research should aim to address the remaining areas of uncertainty which result from the complexity of RV haemodynamics and lack of conclusive evidence regarding RV-specific treatment approaches.

    Background: Air pollution has been demonstrated to be a major risk factor for the development of cardiovascular and respiratory diseases worldwide. This study examines the relationship between the exposure to fine particulate matter (PM) and patient hospitalizations as a result of ischemic heart disease (IHD) during 2013–2014 in Shanghai, China. Methods: Daily IHD hospitalization data were acquired from the Shanghai Health Insurance Bureau (SHIB) from 1 January 2013 to 21 December 2014. Daily average concentrations of air pollution as well as meteorological data were obtained from the database of Shanghai Environmental Monitoring Center (SEMC) during the same time period, and all data were analyzed using standard epidemiological methodology. Generalized linear model (GLM) adjusted for time trends, weather conditions, and medical insurance policy was used to estimate the immediate and delayed effects of PMs on IHD hospitalizations, and the effects of PMs were also examined based on gender, age group and seasonal variation. Results: A total of 188,198 IHD hospitalizations were recorded during 2013–2014 in Shanghai, China. During this period, the average concentrations of the fine particulate matter with aerodynamic diameter of <10 μm (PM10) and ≤2.5 (PM2.5) were 76 µg/m3 and 56.3 µg/m3, respectively. The effect of PMs was strongest on days when a 10 μg/m3 increment increase of PM2.5 and PM10, which coincided with an increase in IHD hospitalizations by 0.25% (95% CI: 0.10%, 0.39%) and 0.57% (95% CI: 0.46%, 0.68%), respectively. Furthermore, the effect of PMs was significantly greater in males and people between 41 and 65 years old. Conclusions: Hospitalizations of IHD was strongly associated with short-term exposure to high levels of PM10 and PM2.5 during 2013–2014 in Shanghai, China. PMID:28208759

    A total of 39 titles related to rheumatic fever or rheumatic heart disease in Malaysia were found with online literature search dating back to their inceptions and through 2014. Additional publications from conference journals were included. Nine papers were selected based on clinical relevance and future research implications. There were no population-based studies on the incidence or prevalence of ARF or RHD. In the 1980s, the incidence of admission due to ARF ranged from 2 to 21.1 per 100 000 paediatric admission per year. The burden of disease was significant in the adult population; 74.5% of patients with RHD were female, of which 77.1% were in the reproductive age group of 15-45 years old. Rheumatic mitral valve disease constituted almost half (46.7%) of all mitral valve repairs, ranging from 44.8 - 55.8 patients per year from 1997 - 2003. From 2010-2012, mitral valve interventions increased to 184 per year, of which 85.7% were mitral valve repair. In children with ARF, 25.4% - 41.7% had past history of rheumatic fever or RHD. In patients with rheumatic mitral valve disease undergoing surgical or medical interventions, only 6% reported history of ARF, none had history of GABHS pharyngitis or antibiotic prophylaxis. Only 44.7% of patients with RHD on follow-up were on intramuscular benzathine penicillin prophylaxis. Overall, there is scarcity of publications on ARF and RHD in Malaysia. Priority areas for research include determination of the incidence and prevalence of ARF and RHD, identification of high-risk populations, evaluation on the implementation and adherence of secondary preventive measures, identification of subclinical RHD especially amongst the high-risk population, and a surveillance system to monitor and evaluate preventive measures, disease progression and outcomes.

    Chemokines, including RANTES, play a crucial role in the processes of inflammation during cardiovascular disorders, including myocardial infarction, disease progression and complications. This study aimed to evaluate the role of RANTES -403G/A polymorphism and levels in circulation in processes of development and progression of myocardial infarction and cardiogenic shock. A total of 609 patients with ST-segment elevation myocardial infarction, 43 patients with cardiogenic shock and 130 control subjects were enrolled in the study. RANTES -403G/A promoter polymorphism and baseline serum RANTES levels were analyzed. In the present study, we associated RANTES -403G/A promoter polymorphism with acute heart failure in patients with myocardial infarction (p = 0.006) and ejection fraction 3 months after MI onset (p = 0.02). Further, a difference in circulating RANTES levels among controls and STEMI subjects, and a relation of serum levels with acute heart failure was observed (p = 0.03, p = 0.003, respectively). We found a significant difference when comparing cardiogenic shock patients and controls (p shock and AHF subgroup of STEMI patients (p shock (cutoff level ≥80.4 ng/ml). Our results suggest the role of RANTES as a potential biomarker of cardiogenic shock and acute heart failure in the hospital phase after myocardial infarction.

    Full Text Available OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome, a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2% had ST-elevation myocardial infarction (STEMI, 288 (39.0% had non-ST-elevation myocardial infarction (NSTEMI and 242 (32.8% had unstable angina (UA. The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76% and sedentarism (73.4%. Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001 and dyslipidemia (p = 0.03. Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006. CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

    We examined whether low-dose L-DOPA treatment induces natriuresis and diuresis in patients with congestive heart failure who have cardiac decompensation despite treatment with digoxin, a diuretic, and an angiotensin-converting enzyme inhibitor and who respond acutely to intravenously infused dopamine. In a randomized, double-blind, placebo-controlled crossover study, 11 patients with severe congestive heart failure received L-DOPA (0.10 g, p.o., t.i.d., for 1 day and then 0.25 g, p.o., t.i.d., for 2 days after a washout period of > or = 1 day), with assessments of plasma and urinary levels of catechols, urinary volume, and sodium content, and clinical and laboratory measures of improvement of congestive heart failure. L-DOPA elicited short-term, dose-related increases in urinary volume and sodium excretion. At the 0.10-g dose, L-DOPA increased plasma L-DOPA levels and urinary L-DOPA excretion by about fivefold, whereas at the 0.25-g dose, L-DOPA increased plasma and urinary L-DOPA by >50-fold. Twenty-four-hour urinary dopamine excretion increased by about fivefold after the low dose of L-DOPA and approximately 50-fold after the high dose. The results demonstrate that oral L-DOPA treatment can produce beneficial natriuretic and diuretic effects in selected patients with congestive heart failure. The bioavailability of oral L-DOPA appears to vary with the dose. These results support findings from previous studies about beneficial cardiac functional effects of L-DOPA in patients with refractory heart failure.

    Full Text Available Abstract Background Optimal management of acute right heart failure following the implantation of a left ventricular assist device requires a reliable estimation of left ventricular preload and contractility. This is possible by real-time pump blood flow measurements. Clinical case We performed implantation of a continuous flow left ventricular assist device in a 66 years old female patient with an end-stage heart failure on the grounds of a dilated cardiomyopathy. Real-time pump blood flow was directly measured by an ultrasonic flow probe placed around the outflow graft. Diagnosis The progressive decline of real time flow and the loss of pulsatility were associated with an increase of central venous pressure, inotropic therapy and progressive renal failure suggesting the presence of an acute right heart failure. Diagnosis was validated by echocardiography and thermodilution measurements. Treatment Temporary mechanical circulatory support of the right ventricle was successfully performed. Real time flow measurement proved to be a useful tool for the diagnosis and ultimately for the management of right heart failure including the weaning from extracorporeal membrane oxygenation.

    Background Most data about psychological factors relating to acute myocardial infarction (AMI) were obtained from studies carried out in western countries. Results from small descriptive cross-sectional studies in China were inconclusive. The aim of this study was to explore possible associations between psychological risk factors and AMI among the Chinese population with a large-scale case-control study.Methods This study was part of the INTER-HEART China study, itself part of the large international INTER-HEART study of cardiovascular risk factors. In this case-control study, 2909 cases and 2947 controls were recruited from 17 cities.Psychological stress, negative life events, depression and controllability of life circumstances were assessed.Results Cases reported more psychological stress at home or work and odds ratios (ORs) were 3.2 (95% CI 2.1-4.9)for permanent stress and 2.1 (95% CI 1.5-2.8) for several periods of stress respectively. More cases experienced depression compared with controls (19.6% vs. 9.3%) and ORs were 2.2 (95% CI 1.9-2.6). Subjects with 1, 2 and 3 or more depressive symptoms had increased risk of AMI by 2.1, 2.2 and 2.6 fold, respectively, i.e., more depressive symptoms were associated with higher risks of AMI (P for trend <0.0001). Women had a greater risk of AMI from depression (OR 3.0, 95% CI 2.2-4.0) compared to men (OR 2.0, 95% CI 1.6-2.4), P for interaction =0.0364. Negative life events in subjects were associated with increased risk of AMI, OR 1.7 (95% CI 1.4-2.0) for one event and 1.8 (95% CI 1.3-2.4) for two or more events. High levels of controllability of life circumstances reduced the risk for AMI (OR 0.8, 95%CI 0.7-1 .0).Conclusions Several psychological factors were closely associated with increased AMI risk among Chinese population.Psychological stress had a greater AMI risk in men but depression was more significant among women.

    Full Text Available The objectives of this study were to evaluate and compare the use of linear and nonlinear methods for analysis of heart rate variability (HRV in healthy subjects and in patients after acute myocardial infarction (AMI. Heart rate (HR was recorded for 15 min in the supine position in 10 patients with AMI taking β-blockers (aged 57 ± 9 years and in 11 healthy subjects (aged 53 ± 4 years. HRV was analyzed in the time domain (RMSSD and RMSM, the frequency domain using low- and high-frequency bands in normalized units (nu; LFnu and HFnu and the LF/HF ratio and approximate entropy (ApEn were determined. There was a correlation (P < 0.05 of RMSSD, RMSM, LFnu, HFnu, and the LF/HF ratio index with the ApEn of the AMI group on the 2nd (r = 0.87, 0.65, 0.72, 0.72, and 0.64 and 7th day (r = 0.88, 0.70, 0.69, 0.69, and 0.87 and of the healthy group (r = 0.63, 0.71, 0.63, 0.63, and 0.74, respectively. The median HRV indexes of the AMI group on the 2nd and 7th day differed from the healthy group (P < 0.05: RMSSD = 10.37, 19.95, 24.81; RMSM = 23.47, 31.96, 43.79; LFnu = 0.79, 0.79, 0.62; HFnu = 0.20, 0.20, 0.37; LF/HF ratio = 3.87, 3.94, 1.65; ApEn = 1.01, 1.24, 1.31, respectively. There was agreement between the methods, suggesting that these have the same power to evaluate autonomic modulation of HR in both AMI patients and healthy subjects. AMI contributed to a reduction in cardiac signal irregularity, higher sympathetic modulation and lower vagal modulation.

    A 75-year-old male with compensated Child-Pugh B cirrhosis initiated sofosbuvir plus simeprevir, and developed hepatic decompensation and died a few days thereafter. High exposure to simeprevir leading to hepatotoxicity most likely explained this fatal outcome. This observation, along with similar cases recently reported in the literature, should raise awareness of the potential for decompensation in patients with advanced cirrhosis treated with simeprevir.

    Background Identifying non-invasive and reliable blood-derived biomarkers for early detection of acute cellular rejection in heart transplant recipients is of great importance in clinical practice. MicroRNAs are small molecules found to be stable in serum and their expression patterns reflect both physiological and underlying pathological conditions in human. Methods We compared a group of heart transplant recipients with histologically-verified acute cellular rejection (ACR, n = 26) with a control group of heart transplant recipients without allograft rejection (NR, n = 37) by assessing the levels of a select set of microRNAs in serum specimens. Results The levels of seven microRNAs, miR-142-3p, miR-101-3p, miR-424-5p, miR-27a-3p, miR-144-3p, miR-339-3p and miR-326 were significantly higher in ACR group compared to the control group and could discriminate between patients with and without allograft rejection. MiR-142-3p and miR-101-3p had the best diagnostic test performance among the microRNAs tested. Serum levels of miR-142-3p and miR-101-3p were independent of calcineurin inhibitor levels, as measured by tacrolimus and cyclosporin; kidney function, as measured by creatinine level, and general inflammation state, as measured by CRP level. Conclusion This study demonstrated two microRNAs, miR-142-3p and miR-101-3p, that could be relevant as non-invasive diagnostic tools for identifying heart transplant patients with acute cellular rejection.

    Highlights: • PM{sub 2.5} induces heart mitochondrial morphological damage of rats. • Mitochondrial fission/fusion gene expression is important regulation mechanism. • Proinflammatoy cytokine level changes are accompanied with mitochondrial damage. • Alterations in oxidative stress and calcium homeostasis are focused on. - Abstract: Epidemiological studies suggested that ambient fine particulate matter (PM{sub 2.5}) exposure was associated with cardiovascular disease. However, the underlying mechanism, especially the mitochondrial damage mechanism, of PM{sub 2.5}-induced heart acute injury is still unclear. In this study, the alterations of mitochondrial morphology and mitochondrial fission/fusion gene expression, oxidative stress, calcium homeostasis and inflammation in hearts of rats exposed to PM{sub 2.5} with different dosages (0.375, 1.5, 6.0 and 24.0 mg/kg body weight) were investigated. The results indicated that the PM{sub 2.5} exposure induced pathological changes and ultra-structural damage in hearts such as mitochondrial swell and cristae disorder. Furthermore, PM{sub 2.5} exposure significantly increased specific mitochondrial fission/fusion gene (Fis1, Mfn1, Mfn2, Drp1 and OPA1) expression in rat hearts. These changes were accompanied by decreases of activities of superoxide dismutase (SOD), Na{sup +}K{sup +}-ATPase and Ca{sup 2+}-ATPase and increases of levels of malondialdehyde (MDA), inducible nitric oxide synthase (iNOS) and nitric oxide (NO) as well as levels of pro-inflammatory mediators including TNF-α, IL-6 and IL-1β in rat hearts. The results implicate that mitochondrial damage, oxidative stress, cellular homeostasis imbalance and inflammation are potentially important mechanisms for the PM{sub 2.5}-induced heart injury, and may have relations with cardiovascular disease.

Analysis of the ACHD (ICD-10 codes: I21.0-I22.9, I20.0, I24 morbidity, mortality and lethality, depending on sex and age was performed in the population (n=285 736; 46% men of several city administrative districts of Voronezh, Ryazan and Khanty-Mansiysk. Morbidity, mortality and lethality were calculated on the basis of medical documentation as well as cases identified by the study protocol.Results. The ACHD morbidity and mortality in men were 1.99 and 1.79 times higher (p<0,001, respectively, than these in women. The studied parameters increase with age, reaching a maximum in 50-59 y.o., have a plateau in 60-79 y.o. and then they decrease. Morbidity and mortality in women increase with age, but reach a maximum in 70-79 y.o., being comparable with the male level, and then exceed it in ≥80 y.o. Age curve of lethality in men has J-alike shape with minimum in patients of 50-79 y.o. Women have a line age curve with minimum in patients of <50 y.o.Conclusion. The population of ACHD patients should be considered according to both the sex and age: <50, 50-79 and ≥80 y.o. Every of these population group has special epidemiological characteristics.

    Increased aortic stiffness may be an important cause of acute heart failure (AHF). Clinical scenario (CS), which classifies the pathophysiology of AHF based on the initial systolic blood pressure (sBP), was proposed to provide the most appropriate therapy for AHF patients. In CS, elevated aortic stiffness, vascular failure, has been considered as a feature of patients categorized as CS1 (sBP > 140 mmHg at initial presentation). However, whether elevated aortic stiffness, vascular failure, is present in such patients has not been fully elucidated. Therefore, we assessed aortic stiffness in AHF patients using the cardio-ankle vascular index (CAVI), which is considered to be independent of instantaneous blood pressure. Sixty-four consecutive AHF patients (mean age, 70.6 ± 12.8 years; 39 men) were classified with CS, based on their initial sBP: CS1: sBP > 140 mmHg (n = 29); CS2: sBP 100-140 mmHg (n = 22); and CS3: sBP 100 mmHg (n = 13). There were significant group differences in CAVI (CS1 vs. CS2 vs. CS3: 9.7 ± 1.4 vs. 8.4 ± 1.7 vs. 8.3 ± 1.7, p = 0.006, analysis of variance). CAVI was significantly higher in CS1 than in CS2 (p = 0.02) and CS3 (p = 0.04). CAVI did not significantly correlate with sBP at the time of measurement of CAVI (r = 0.24 and p = 0.06). Aortic stiffness assessed using blood pressure-independent methodology apparently increased in CS1 AHF patients. We conclude that vascular failure is a feature of CS1 AHF initiation.

    To investigate the role of perfusion defect (PD) size on dual energy CT pulmonary blood volume assessment as predictor of right heart strain and patient outcome and its correlation with d-dimer levels in acute pulmonary embolism (PE). 53 patients with acute PE who underwent DECT pulmonary angiography were retrospectively analyzed. Pulmonary PD size caused by PE was measured on DE iodine maps and quantified absolutely (VolPD) and relatively to the total lung volume (RelPD). Signs of right heart strain (RHS) on CT were determined. Information on d-dimer levels and readmission for recurrent onset of PE and death was collected. D-dimer level was mildly (r = 0.43-0.47) correlated with PD size. Patients with RHS had significantly higher VolPD (215 vs. 73 ml) and RelPD (9.9 vs. 2.9%) than patients without RHS (p < 0.003). There were 2 deaths and 1 readmission due of PE in 18 patients with >5% RelPD, while no such events were found for patients with <5% RelPD. Pulmonary blood volume on DECT in acute PE correlates with RHS and appears to be a predictor of patient outcome in this pilot study. (orig.)

    Cardiotoxicity is an emerging concern with a new class of drugs known as targeted agents, which include trastuzumab and sunitinib. Sunitinib is a small molecule that inhibits multiple tyrosine kinase receptors. This drug was approved by the United States Food and Drug Administration in 2006 for the treatment of clear cell metastatic renal cell carcinoma and advanced gastrointestinal stromal tumors. We describe a 65-year-old woman who was treated with sunitinib for metastatic clear cell renal cell carcinoma. After 5 months of therapy, she developed acute heart failure requiring hospitalization; sunitinib was immediately discontinued. The patient had classic symptoms of heart failure, including pleural effusion. An echocardiogram revealed a left ventricular ejection fraction of 30%. She received standard treatment for heart failure, including a beta-blocker, an angiotensin-converting enzyme inhibitor, and diuretics. Within 1 month, the patient's symptoms resolved, and subsequent cardiac evaluation showed that her left ventricular ejection fraction returned to normal. According to the Common Terminology Criteria for Adverse Events developed by the National Cancer Institute, her cardiac event associated with sunitinib was defined as grade III toxicity. One month later, sorafenib, another tyrosine kinase inhibitor, was started with the aim of continuing her previous response to sunitinib. After 7 months of sorafenib therapy, the patient had no evidence of heart failure, and her condition was responding to treatment. Clinicians should be aware that sunitinib-induced heart failure occurs occultly and that many--but not all--cases resolve with discontinuation of the drug. Use of sorafenib after sunitinib-induced heart failure appears to be safe and effective, which suggests that cardiotoxicity is not a general class effect of the tyrosine kinase inhibitors.

    Objevtive:Super infection with hepatitis A virus (HAV)and hepatitis E virus (HEV)in the presence of un-derlying hepatocellular injury can cause severe illness.In endemic areas such as India,however most patients already have been exposed to HAV but could still be susceptible to HEV infection.In our study we determined the seroprevalence of anti-HAV IgMand anti-HEV IgMto assess the incidence of superinfection with these vi-ruses in cirrhotic patients with the goal of defining the need for protection against these viruses and further cor-relate the presence of these viruses with the clinical course.Methods:We studied 53 patients of cirrhosis as a result of Hepatitis B virus.Apparent causes of decompensation were ruled out before their inclusion in the study group.Serum sample from these patients was tested for HBsAg,anti HBc IgG,anti HEV IgMand anti HAV IgG and IgMby commercially available ELISA kit.Liver function test was done on all the patients and correlated with various serological markers.Results:anti HBc IgG was present in all the cases of cirrhosis. Hepatitis B surface antigen was present in 20 out of 53 cases of cirrhosis.None of the patients demonstrated anti-HAV IgM,however one patient had anti-HEV IgM.Conclusion:Superinfection with HAV in adult pa-tient is uncommon in India.Prevalence of acute HEV infection in decompensated cirrhosis is low in the present study but presence of HEV superinfection in one patient corroborates the apprehension of liver function deterio-ration following superinfection with HEV virus.

    The use of angiotensin converting enzyme (ACE) inhibitors in combination with diuretics is a common strategy used for the treatment of patients affected by heart failure. An infant affected by initial congestive cardiac failure, after starting the treatment with enalapril in association with furosemide, developed acute kidney injury (AKI). No underlying renal disease or renal artery stenosis was found. He recovered from kidney injury after the therapy was suspended, thus suggesting that the drug combination is responsible for the onset of the adverse reaction. The present case report, the appraisal of the current knowledge on the onset of AKI and the analysis of available pharmacovigilance databases indicate that particular caution should be exercised when infants affected by heart failure are treated with the enalapril and furosemide combination therapy. Moreover, we strongly suggest an up-to-date revision of the ACE-inhibitor dosing guidelines in pediatric patients to define unambiguously the safe upper limits of this class of drugs.

    Objectives To investigate the effects of simvastatin on membrane ionic currents in left ventricular myocytes of rab-bit heart suffering from acute myocardial infarction (AMI), so as to explore the ionic mechanism of statin treatment for antiarrhythmia. Methods Forty-five New Zealand rabbits were randomly divided into three groups: AMI group, simv-astatin intervention group (Statin group) and sham-operated control group (CON). Rabbits were infarcted by ligation of the left anterior descending coronary artery after administration of oral simvastatin 5 mg · kg-1 · d-1 (Statin group) or placebo (AMI group) for 3 days. Single ventricular myocytes were isolated enzymatically from the epicardial zone of the infracted region 72 h later. Whole cell patch clamp technique was used to record membrane ionic currents, inclu-ding sodium current (Ina), L-type calcium current (Ica-L) and transient outward potassium current (Ito). Results ① There was not significant difference in serum cholesterol concentration among three groups. ② The peak Ina current den-sity (at -30 mV) was significantly decreased in AMI group (-25.26±5. 28, n = 13), comparing with CON (-42. 78±5.48, n = 16), P < 0. 05, while it was significantly increased in Statin group (-39. 83±5. 65 pA/pF, n = 12) comparing with AMI group, P <0. 01; The peak I Ca-L current density (at 0 mV) was significantly decreased in AMI group (- 3.43±0. 92 pA/pF, n = 13) comparing with CON (- 4. 56±1.01 pA/pF, n = 15), P < 0. 05, while it was significantly increased in Statin group (-4. 18±0. 96 pA/pF, n = 12) comparing with AMI group, P <0. 05; The Ito current density (at + 60 mV) was significantly decreased in AMI group (11.41±1.94 pA/pF, n = 13) compa-ring with CON (17. 41±3. 13 pA/pF, n = 15), P <0. 01, while it was significantly increased in Statin group (16. 11±2. 43 pA/pF, n = 14) comparing with AMI group, P < 0. 01. Conclusions AMI induces significant down-regula-tion of Ina, I Ca-L and Ito. Pretreatment with

    In the setting of acute myocardial infarction and sinus rhythm, the heart rate (HR) has been demonstrated to correlate closely with mortality. In patients presenting with acute myocardial infarction and atrial fibrillation (AF) on admission, however, the prognostic relevance of the HR has not yet been systematically addressed. A post hoc subgroup analysis of the data from the OMEGA trial was conducted to analyze whether the admission HR determines the 1-year mortality in patients presenting with AF in the setting of acute myocardial infarction. Of 3,851 patients enrolled in the OMEGA study, 211 (6%) presented with AF on admission. This subgroup was dichotomized according to the admission HR (cutoff 95 beats/min). Multiple regression analysis revealed that an admission HR of ≥95 beats/min independently determined the 1-year mortality in patients with AF (odds ratio 4.69, 95% confidence interval 1.47 to 15.01; p = 0.01). In conclusion, this is the first study demonstrating that a high HR (≥95 beats/min) on admission in patients with AF and acute myocardial infarction is associated with an almost fivefold mortality risk.

    Inhibition of angiotensin II type 1 receptor (AT1R) is an important therapy in the management of hypertension, particularly in the immediate post-myocardial infarction period. Yet, the role of AT1R in the acute onset of myocardial ischemia and reperfusion injury still remains controversial. Thus, the present study determined the effects of chronic losartan treatment on heart ischemia and reperfusion injury in rats. Losartan (10 mg/kg/day) was administered to six-month-old male rats via an osmotic pump for 14 days and hearts were then isolated and were subjected to ischemia and reperfusion injury in a Langendorff preparation. Losartan significantly decreased mean arterial blood pressure. However, heart weight, left ventricle to body weight ratio and baseline cardiac function were not significantly altered by the losartan treatment. Of interest, chronic in vivo losartan treatment significantly increased ischemia-induced myocardial injury and decreased post-ischemic recovery of left ventricular function. This was associated with significant increases in AT1R and PKCδ expression in the left ventricle. In contrast, AT2R and PKCε were not altered. Furthermore, losartan treatment significantly increased microRNA (miR)-1, -15b, -92a, -133a, -133b, -210, and -499 expression but decreased miR-21 in the left ventricle. Of importance, addition of losartan to isolated heart preparations blocked the effect of increased ischemic-injury induced by in vivo chronic losartan treatment. The results demonstrate that chronic losartan treatment up-regulates AT1R/PKCδ and alters miR expression patterns in the heart, leading to increased cardiac vulnerability to ischemia and reperfusion injury.

    It is generally accepted that the intercalated disc (ICD) required for mechano-electrical coupling in the heart consists of three distinct junctional complexes: adherens junctions, desmosomes and gap junctions. However, recent morphological and molecular data indicate a mixing of adherens junctional and desmosomal components, resulting in a 'hybrid adhering junction' or 'area composita'. The α-catenin family member αT-catenin, part of the N-cadherin-catenin adhesion complex in the heart, is the only α-catenin that interacts with the desmosomal protein plakophilin-2 (PKP2). Thus, it has been postulated that αT-catenin might serve as a molecular integrator of the two adhesion complexes in the area composita. To investigate the role of αT-catenin in the heart, gene targeting technology was used to delete the Ctnna3 gene, encoding αT-catenin, in the mouse. The αT-catenin-null mice are viable and fertile; however, the animals exhibit progressive cardiomyopathy. Adherens junctional and desmosomal proteins were unaffected by loss of αT-catenin, with the exception of the desmosomal protein PKP2. Immunogold labeling at the ICD demonstrated in the αT-catenin-null heart a preferential reduction of PKP2 at the area composita compared with the desmosome. Furthermore, gap junction protein Cx43 was reduced at the ICD, including its colocalization with N-cadherin. Gap junction remodeling in αT-catenin-knockout hearts was associated with an increased incidence of ventricular arrhythmias after acute ischemia. This novel animal model demonstrates for the first time how perturbation in αT-catenin can affect both PKP2 and Cx43 and thereby highlights the importance of understanding the crosstalk between the junctional proteins of the ICD and its implications for arrhythmogenic cardiomyopathy.

    In this study, we have tried to characterize the limits of the approach typically used to determine H2S concentrations in the heart based on the amount of H2S evaporating from heart homogenates-spontaneously, after reaction with a strong reducing agent, or in a very acidic solution. Heart homogenates were prepared from male rats in control conditions or after H2S infusion induced a transient cardiogenic shock (CS) or cardiac asystole (CA). Using a method of determination of gaseous H2S with a detection limit of 0.2 nmol, we found that the process of homogenization could lead to a total disappearance of free H2S unless performed in alkaline conditions. Yet, after restoration of neutral pH, free H2S concentration from samples processed in alkaline and nonalkaline milieus were similar and averaged ∼0.2-0.4 nmol/g in both control and CS homogenate hearts and up to 100 nmol/g in the CA group. No additional H2S was released from control, CS, or CA hearts by using the reducing agent tris(2-carboxyethyl)phosphine or a strong acidic solution (pH H2S from combined pools. Of note, the reducing agent DTT produced a significant sulfide artifact and was not used. These data suggest that 1) free H2S found in heart homogenates is not a reflection of H2S present in a "living" heart and 2) the pool of combined sulfides, released in a strong reducing or acidic milieu, does not increase in the heart in a measurable manner even after toxic exposure to sulfide.

    Background The association of overall diet, as characterized by dietary patterns, with risk of incident acute coronary heart disease (CHD) has not been studied extensively in samples including sociodemographic and regional diversity. Methods and Results We used data from 17,418 participants in Reasons for Geographic and Racial Differences in Stroke (REGARDS), a national, population-based, longitudinal study of white and black adults aged ≥45 years, enrolled from 2003-2007. We derived dietary patterns with factor analysis, and used Cox proportional hazards regression to examine hazard of incident acute CHD events – nonfatal myocardial infarction and acute CHD death – associated with quartiles of consumption of each pattern, adjusted for various levels of covariates. Five primary dietary patterns emerged: Convenience, Plant-based, Sweets, Southern, and Alcohol and Salad. A total of 536 acute CHD events occurred over a median (IQR) 5.8 (2.1) years of follow-up. After adjustment for sociodemographics, lifestyle factors, and energy intake, highest consumers of the Southern pattern (characterized by added fats, fried food, eggs, organ and processed meats, and sugar-sweetened beverages) experienced a 56% higher hazard of acute CHD (comparing quartile 4 to quartile 1: HR = 1.56; 95% CI: 1.17, 2.08; P for trend across quartiles = 0.003). Adding anthropometric and medical history variables to the model attenuated the association somewhat (HR = 1.37; 95% CI: 1.01, 1.85; P = 0.036). Conclusions A dietary pattern characteristic of the southern US was associated with greater hazard of CHD in this sample of white and black adults in diverse regions of the US. PMID:26260732

    Research in Context: Clevidipine lowers blood pressure by inhibiting calcium channels in vascular smooth muscle. In patients with acute heart failure, clevidipine was shown to relieve breathing problems. This was only partially related to the blood pressure lowering actions of clevidipine and not conferred by another calcium channel inhibitor. We here found calcium channel variants in human lung that are more selectively inhibited by clevidipine, especially when associated with pannexin channels. This study gives a possible mechanism for clevidipine's relief of breathing problems and supports future clinical trials testing the role of clevidipine in the treatment of acute heart failure.

    Heart failure is associated with increased risk of morbidity and mortality, resulting in substantial health-care costs. Clinical pharmacists have an opportunity to reduce health-care costs and improve disease management as patients transition from inpatient to outpatient care by leading interventions to develop patient care plans, educate patients and clinicians, prevent adverse drug reactions, reconcile medications, monitor drug levels, and improve medication access and adherence. Through these methods, clinical pharmacists are able to reduce rates of hospitalization, readmission, and mortality. In addition, care by clinical pharmacists can improve dosing levels and adherence to guideline-directed therapies. A greater benefit in patient management occurs when clinical pharmacists collaborate with other members of the health-care team, emphasizing the importance of heart failure treatment by a multidisciplinary health-care team. Education is a key area in which clinical pharmacists can improve care of patients with heart failure and should not be limited to patients. Clinical pharmacists should provide education to all members of the health-care team and introduce them to new therapies that may further improve the management of heart failure. The objective of this review is to detail the numerous opportunities that clinical pharmacists have to improve the management of heart failure and reduce health-care costs as part of a multidisciplinary health-care team.

    Iron deficiency is a frequent comorbidity in a patient with chronic heart failure, and it associates with a worse prognosis of that patient. Mainly worse quality of life and more rehospitalizations are in these iron deficient patients. Iron metabolism is rather complex and there is some new information concerning this complexity in heart failure. We distinquish an absolute and a functional iron deficiency in heart failure. It is this deficit which is important and not as much is anemia important here. Prevalence of anaemia in heart failure is about 30-50%, higher it is in patients suffering more frequently heart failure decompensations. Treatment of iron deficiency is important and it improves prognosis of these patients. Most experiences there are with i.v. iron treatment (FERRIC HF, FAIR HF and CONFIRM HF studies), less so with per oral treatment. There are no clinical trials which analysed mortality influences.

    A growing population experiencing heart failure (100,000 patients/year), combined with a shortage of donor organs (less than 2200 hearts/year), has led to increased and expanded use of mechanical circulatory support (MCS) devices. MCS devices have successfully improved clinical outcomes, which are comparable with heart transplantation and result in better 1-year survival than optimal medical management therapies. The quality of perfusion provided during MCS therapy may play an important role in patient outcomes. Despite demonstrated physiologic benefits of pulsatile perfusion, continued use or development of pulsatile MCS devices has been widely abandoned in favor of continuous flow pumps owing to the large size and adverse risks events in the former class, which pose issues of thrombogenic surfaces, percutaneous lead infection, and durability. Next-generation MCS device development should ideally implement designs that offer the benefits of rotary pump technology while providing the physiologic benefits of pulsatile end-organ perfusion.

    Heart failure had a higher incidence in cardiovascular diseases. Almost all heart disease sand vascular diseases can cause heart failure. Acute heart failure was caused by the sudden increase due to acute myocardial serious injury, or cardiac stress caused by a sharp deterioration of the heart in a short time., It was a great threat to the safety of patients having acute heart failure without timely and effective treatment. Pathogenesis of acute heart failure was sudden increase of pulmonary venous pressure and the abrupt decline of the cardiac output. The major causes were coronary heart disease, hypertension and infectious endocarditis. Related research also showed that the occurrence of acute heart failure was related with patients with low level of vitamin D. which has become a popular medical research of heart failure.%心力衰竭在心血管疾病中有着较高的发病率,几乎所有的心脏病类型及大血管的疾病均能够引起心力衰竭的发生.急性心力衰竭则是由于急性的心肌严重损伤或者心脏负荷突然加重而引起心脏在短时间内发生急剧的恶化.发生急性心力衰竭以后,如果不能进行及时有效的救治就会给患者的生命安全带来极大的威胁.急性心力衰竭的发病机制主要是各种原因导致肺静脉压突然升高及心脏的排血量急骤下降,主要病因与冠心病、高血压及感染性的心内膜炎有关.相关的研究还显示,急性心衰的发生与患者体内的维生素D水平低下有关,近年来关于此方面的研究已经成为医学上的热门研究内容.

    The onset of hepatic decompensation in cirrhosisheralds an accelerated downhill course with pooroutcome. The sole predictor of this decompensation in cirrhosis is increased hepatic vein to portal veingradient hepatic venous pressure gradient (HVPG).Surrogate markers of liver function or hepatic reserveappear to be less relevant. The hepatic sinusoidsbecome less elastic and more rigid as liver fibrosisand cirrhosis progress. We propose that the Hagen-Poiseuille's law, which applies to rigid, but not elasticvessels, determines the pressure-flow characteristicsin the sinusoids. In the rigid cirrhotic liver, HVPG risesdramatically with any change in net surface areaor radius, r4 of the vasculature that follows surgicalresection. This review relates liver stiffness to therisk of decompensation in patients with cirrhosis. Theliver has a unique dual blood supply comprising a lowpressure portal vein and high pressure hepatic artery.We compare the complexity of autoregulation in thenormal elastic liver with that in the rigid cirrhotic liver.Therapeutic modalities to reduce portal pressure mayreduce the risk of hepatic decompensation and improveoutcomes in cirrhosis.

    AIM: To study the metabolic profiling of serum samples from compensated and decompensated cirrhosis patients.METHODS: A pilot metabolic profiling study was conducted using three groups: compensated cirrhosis patients (n = 30), decompensated cirrhosis patients (n = 30) and healthy controls (n = 30). A 1H nuclear magnetic resonance (NMR)-based metabonomics approach was used to obtain the serum metabolic profiles of the samples. The acquired data were processed by multivariate principal component analysis and orthogonal partial least-squares discriminant analysis (OPLS-DA). RESULTS: The OPLS-DA model was capable of distinguishing between decompensated and compensated cirrhosis patients, with an R2Y of 0.784 and a Q2Y of 0.598. Twelve metabolites, such as pyruvate, phenylalanine and succinate, were identified as the most influential factors for the difference between the two groups. The validation of the diagnosis prediction showed that the accuracy of the OPLSDA model was 85% (17/20). CONCLUSION: 1H NMR spectra combined with pattern recognition analysis techniques offer a new way to diagnose compensated and decompensated cirrhosis in the future.

    Full Text Available At present, liver transplantation remains the only curative option for the patients with cirrhosis and end-stage liver diseases. The survival rate and recurrent diseases remain the major issues in the patient post-transplantation. Unani medicine is one of the oldest traditional systems of medicine which has been treating chronic liver diseases and cirrhosis (Talayyaful-Kabid for centuries. The current study aimed to assess the impact of Unani treatment on decompensated cirrhosis and collect data to warrant further clinical trials. Authors conducted a case series on five patients with decompensated cirrhosis and portal hypertension. The disease was confirmed through FibroScan and ultrasound and treated with Unani treatment orally for seven months. Results were evaluated based on FibroScan, liver function test (LFT, EuroQol-5D (EQ5D, Child-Pugh and TTO-TIME (trade-off question. Significant improvements in LFT, fibrosis and quality of life were achieved in the studied patients. The literature related to the herbal constituents of chief medicines used to treat in this case was reviewed. The herbs proved their potential anti-oxidative, anti-inflammatory, hepato-protective, immuno-modulator and antiviral activities, suggesting plausible mechanisms of action in the cases. The preliminary findings indicated the potential therapeutic role of Unani treatment in decompensated cirrhosis. Clinical trials should be conducted to explore further therapeutic potential of Unani treatment in decompensated cirrhosis.

    Background Most HCC patients with decompensation of liver function lost the chance of surgical and/or interventional treatment. The aim of this study was to evaluate feasibility and outcome of radiofrequency ablation (RFA) in treating hepatocellular carcinoma (HCC) patients with poor liver function (Child-Pugh class C), who are not suitable for surgery or hepatic artery chemo-embolization.Methods Thirteen HCC patients (the number of tumors was 17) with liver function of Child-Pugh C (scores: 10.2±0.4)were included in the study. Among the patients, 8 were male and 5 were female with the average age of (61.6±10.9)years old. The average size of HCC was (3.8±1.0) cm. Two patients were recurrent HCC and 30.8% of the patients had multiple tumors (2-3 tumors). All the patients were treated with RFA.Results There were 22 RFA sessions (1-4 sessions per patient) in all, average ablations per tumor at first session was 3.1. One week after RFA, the liver enzymes elevated in 9 patients (69.2%), in 7 of them, the liver enzyme returned to pre-RFA level in 1-3 months. One month after RFA, the Child-Pugh grading was 10.3±0.8 (Child-Pugh C), while that of pre-RFA was 10.2±0.4 (Child-Pugh C), with no significant difference. Computer tomography (CT) one month after RFA showed that the tumor necrosis rate was 88.2% (15/17). Five patients had 2-4 repeated RFA due to HCC recurrence.During the follow-up of 2-69 months in this group, survival rate of one year was 53.8%, two years was 30.8%, and three year was 15.4%. The incidence of RFA-related complications was 13.6% (3/22 sessions), including 1 case of GI hemorrhage and 1 sub-capsular hemorrhage of the liver. One patient with HCC over 5 cm who had fever and liver abscess after RFA, and was dead 2 months later due to liver function failure.Conclusions Minimal invasive RFA provides possible treatment modality for HCC patients with poor liver function, who are not candidates for surgical and/or interventional therapy.

    Background Mesenchymal stem cells (MSCs) transplantation is of therapeutic potential after ischemic injury in both experimental and clinical studies.Clinically,elderly patients are more vulnerable to acute myocardial infarction (AMI).But little is known about the characteristics of young donor-derived MSCs transplanted to old patients with AMI.The present study was designed to investigate the effect of transplanted MSCs from rats of different ages on the improvement of heart function after AMI.Methods MSCs from Sprague-Dawley (SD) rats were isolated and cultured in vitro.The apoptosis characteristics of MSCs were observed under conditions of ischemia and anoxia.SD rats underwent MI received intramyocardial injection of MSCs from young donor rats (n=8),old donor rats (n=8),respectively.AMI control group received equal volume physiological saline.Immunofluorescence was used to observe the differentiation of the grafted cells into cardiomyocytes.Four weeks after cell transplantation, reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry for vascular endothelial growth factor (VEGF),VIII-factor immunohistochemistry for vessel density,TUNEL,caspase-3 for cardiomyocyte apoptosis,echocardiography and hemodynamic detection for heart function were performed.Results The apoptosis rate of the old donor-derived MSCs group was significantly higher than that of the young donor-derived MSCs group under conditions of ischemia and anoxia (P <0.05).Engrafted MSCs survived,proliferated and differentiated into myocardium-like cells.VEGF gene expression and capillary density in the old donor-derived group were lower than those in the young donor-derived group but higher than those in the control group (P <0.05).The transplantation of old donor-derived MSCs attenuated apoptosis of cadiomyocytes in the peri-infract region compared with the control group and the effect was elevated in young donor-derived MSCs (P <0.05).The heart functions (left ventricle

    The management of depression and other negative psychological states in cardiac patients has been a focus of multiple treatment trials, though such trials have not led to substantial improvements in cardiac outcomes. In contrast, there has been minimal focus on interventions to increase positive psychological states in cardiac patients, despite the fact that optimism and other positive states have been associated with superior cardiovascular outcomes. Our objective was to develop an 8-week, phone-based positive psychology intervention for patients hospitalized with acute cardiac disease (acute coronary syndrome or decompensated heart failure). Such an intervention would consist of positive psychology exercises adapted for this specific population, and it would need to be feasible for practitioners and patients in real-world settings. By adapting exercises that were previously validated in healthy individuals, we were able to generate a positive psychology telemedicine intervention for cardiac patients that focused on optimism, kindness, and gratitude. In addition, we successfully created a companion treatment manual for subjects to enhance the educational aspects of the intervention and facilitate completion of exercises. Finally, we successfully performed a small pilot trial of this intervention, and found that the positive psychology intervention appeared to be feasible and well-accepted in a cohort of patients with acute cardiac illness. Future studies should further develop this promising intervention and examine its impact on psychological and medical outcomes in this vulnerable population of cardiac patients.

    ♦ Background: Previous small studies have reported favorable results of peritoneal dialysis (PD) in the setting of chronic refractory heart failure (CRHF). We evaluated the impact of PD in a larger cohort of patients with CHRF where end-stage renal disease was excluded. ♦ Methods: All patients who received PD therapy for CRHF between January 1995 and December 2010 in two medical centers in France were included in this retrospective study. Baseline characteristics were compared with clinical parameters during the first year after initiation of PD. Mortality, safety, and sustainability of PD were also analyzed. ♦ Results: The 126 patients included had a mean age of 72 ± 11 years and an estimated glomerular filtration rate of 33.5 ± 15.1 mL/min/1.73 m2. Mean time on PD was 16 ± 16.6 months. During the first year, patients with a left ventricular ejection fraction (LVEF) of 30% or less experienced improvement in cardiac function (30% ± 10% vs 20% ± 6%, p < 0.0001). We observed a significant reduction in the number of days of hospitalization for acute decompensated heart failure after PD initiation (3.3 ± 2.6 days/patient-month vs 0.3 ± 0.5 days/patient-month, p < 0.0001). One-year mortality was 42%. ♦ Conclusions: In CRHF, PD significantly reduces the number of days of hospitalization for acute heart failure. Improved LVEF may have led to the comparatively good 1-year survival in this cohort. PMID:23994842

    Heart failure with preserved ejection fraction (HFpEF) has been described as a disease of elderly subjects with female predominance and hypertension. Our clinical experience suggests patients with HFpEF from an urban population are far more heterogenous, with greater co-morbidities and significant inhospital morbidity. There are limited data on the hospitalization course and outcomes in acute decompensated HFpEF. Hospitalizations for acute heart failure at our institution from July 2011 to June 2012 were identified by International Classification of Diseases, Ninth Revision, codes and physician review for left ventricular ejection fraction ≥50% and were reviewed for patient characteristics and clinical outcomes. Worsening renal function (WRF) was defined as creatinine increase of ≥0.3 mg/dl by 72 hours after admission. Hospital readmission and mortality data were captured from electronic medical records and the Social Security Death Index. Of 434 heart failure admissions, 206 patients (47%) with HFpEF were identified. WRF developed in 40%, the highest reported in HFpEF to date, and was associated with higher blood pressure and lower volume of diuresis. Compared to previous reports, hospitalized patients with HFpEF were younger (mean age 63.2 ± 13.6 years), predominantly black (74%), and had more frequent and severe co-morbidities: hypertension (89%), diabetes (56%), and chronic kidney disease (55%). There were no significant differences in 1- and 12-month outcomes by gender, race, or WRF. In conclusion, we found hospitalized patients with HFpEF from an urban population develop a high rate of WRF are younger than previous cohorts, often black, and have greater co-morbidities than previously described.

    Although beta-adrenergic blockade is beneficial in heart failure, inhibition of central sympathetic outflow using moxonidine has been associated with increased mortality. In the present study, we studied the acute effects of the imidazoline-receptor agonist moxonidine on haemodynamics, NA (noradrenaline) kinetics and myocardial metabolism. Fifteen patients with CHF (chronic heart failure) were randomized to a single dose of 0.6 mg of sustained-release moxonidine or matching placebo. Haemodynamics, NA kinetics and myocardial metabolism were studied over a 2.5 h time period. There was a significant reduction in pulmonary and systemic arterial pressures, together with a decrease in cardiac index in the moxonidine group. Furthermore, there was a simultaneous reduction in systemic and cardiac net spillover of NA in the moxonidine group. Analysis of myocardial consumption of substrates in the moxonidine group showed a significant increase in non-esterified fatty acid consumption and a possible trend towards an increase in myocardial oxygen consumption compared with the placebo group (P=0.16). We conclude that a single dose of moxonidine (0.6 mg) in patients already treated with a beta-blocker reduced cardiac and overall sympathetic activity. The finding of increased lipid consumption without decreased myocardial oxygen consumption indicates a lack of positive effects on myocardial metabolism under these conditions. We suggest this might be a reason for the failure of moxonidine to prevent deaths in long-term studies in CHF.

    Acute heart failure (AHF) is frequently associated with worsening renal function in adult patients. Neutrophil gelatinase-associated lipocalin (NGAL) serves as an early marker for acute renal tubular injury. To assess the role of plasma NGAL in predicting worsening renal function (WRF) in children with AHF, we studied 30 children hospitalized for AHF; children with history of chronic renal disease or on nephrotoxic drugs were excluded. Twenty age- and sex-matched healthy children were included in the study as a control group. Echocardiographic examination was performed on admission. Blood urea nitrogen (BUN), serum creatinine, estimated glomerular filtration rate (eGFR) and plasma NGAL levels were measured on admission and 72 h later. Seventeen (56.6%) patients developed WRF within the three-day follow-up period. At presentation, plasma NGAL level was significantly elevated in children who developed WRF. Admission plasma NGAL level correlated with renal parameters (BUN, creatinine and eGFR) as well as with left ventricular systolic parameters (ejection fraction and fractional shortening). For prediction of WRF, admission plasma, NGAL level>27.5 μg/L had sensitivity and specificity of 90% and 68%, respectively. The area under the receiver-operator curve was higher for NGAL (0.869) than for BUN (0.569) or eGFR (0.684). We conclude that admission plasma NGAL level can predict WRF in children hospitalized for AHF.

    Growing concern for falls in acute care settings could be addressed with objective evaluation of fall risk. The current proof-of-concept study evaluated the feasibility of using a chest-worn sensor during hospitalization to determine fall risk. Physical activity and heart rate variability (HRV) of 31 volunteers admitted to a 29-bed adult inpatient unit were recorded using a single chest-worn sensor. Sensor data during the first 24-hour recording were analyzed. Participants were stratified using the Hendrich II fall risk assessment into high and low fall risk groups. Univariate analysis revealed age, daytime activity, nighttime side lying posture, and HRV were significantly different between groups. Results suggest feasibility of wearable technology to consciously monitor physical activity, sleep postures, and HRV as potential markers of fall risk in the acute care setting. Further study is warranted to confirm the results and examine the efficacy of the proposed wearable technology to manage falls in hospitals. [Journal of Gerontological Nursing, xx(x), xx-xx.].

    Full Text Available It remains difficult to predict and to measure the efficacy of pharmacological immunosuppression. We hypothesized that measuring the B-cell repertoire would enable assessment of the overall level of immunosuppression after heart transplantation.In this proof-of-concept study, we implemented a molecular-barcode-based immune repertoire sequencing assay that sensitively and accurately measures the isotype and clonal composition of the circulating B cell repertoire. We used this assay to measure the temporal response of the B cell repertoire to immunosuppression after heart transplantation. We selected a subset of 12 participants from a larger prospective cohort study (ClinicalTrials.gov NCT01985412 that is ongoing at Stanford Medical Center and for which enrollment started in March 2010. This subset of 12 participants was selected to represent post-heart-transplant events, with and without acute rejection (six participants with moderate-to-severe rejection and six without. We analyzed 130 samples from these patients, with an average follow-up period of 15 mo. Immune repertoire sequencing enables the measurement of a patient's net state of immunosuppression (correlation with tacrolimus level, r = -0.867, 95% CI -0.968 to -0.523, p = 0.0014, as well as the diagnosis of acute allograft rejection, which is preceded by increased immune activity with a sensitivity of 71.4% (95% CI 30.3% to 94.9% and a specificity of 82.0% (95% CI 72.1% to 89.1% (cell-free donor-derived DNA as noninvasive gold standard.

This subset of 12 participants was selected to represent post-heart-transplant events, with and without acute rejection (six participants with moderate-to-severe rejection and six without). We analyzed 130 samples from these patients, with an average follow-up period of 15 mo. Immune repertoire sequencing enables the measurement of a patient’s net state of immunosuppression (correlation with tacrolimus level, r = −0.867, 95% CI −0.968 to −0.523, p = 0.0014), as well as the diagnosis of acute allograft rejection, which is preceded by increased immune activity with a sensitivity of 71.4% (95% CI 30.3% to 94.9%) and a specificity of 82.0% (95% CI 72.1% to 89.1%) (cell-free donor-derived DNA as noninvasive gold standard). To illustrate the potential of immune repertoire sequencing to monitor atypical post-transplant trajectories, we analyzed two more patients, one with chronic infections and one with amyloidosis. A larger, prospective study will be needed to validate the power of immune repertoire sequencing to predict rejection events, as this proof-of-concept study is limited to a small number of patients who were selected based on several

    Full Text Available AIM: We investigated the relationships between the autonomic nervous system, as assessed by heart rate variability (HRV and levels of N-terminal Pro-B-type Natriuretic Peptide (Nt-proBNP in patients with acute myocardial infarction (MI. METHODS AND RESULTS: The mean of standard deviation of RR intervals (SDNN, the percentage of RR intervals with >50 ms variation (pNN50, square root of mean squared differences of successive RR intervals (rMSSD, and frequency domain parameters (total power (TP, high frequency and low frequency power ratio (LF/HF were assessed by 24 h Holter ECG monitoring. 1018 consecutive patients admitted <24 h for an acute MI were included. Plasma Nt-proBNP (Elecsys, Roche was measured from blood samples taken on admission. The median (IQR Nt-proBNP level was 681(159-2432 pmol/L. Patients with the highest quartile of Nt-proBNP were older, with higher rate of risk factors and lower ejection fraction. The highest Nt-proBNP quartile group had the lowest SDNN, LF/HF and total power but similar pNN50 and rMSSD levels. Nt-proBNP levels correlated negatively with SDNN (r = -0.19, p<0.001, LF/HF (r = -0.37, p<0.001, and LF (r = -0.29, p<0.001 but not HF (r = -0.043, p = 0.172. Multiple regression analysis showed that plasma propeptide levels remained predictive of LF/HF (B(SE = -0.065(0.015, p<0.001, even after adjustment for confounders. CONCLUSIONS: In conclusion, our population-based study highlights the importance of Nt-proBNP levels to predict decreased HRV after acute MI.

    Heart failure (HF) is an important public health problem, and strategies are needed to improve outcomes and decrease health care resource utilization and costs. Its prevalence has increased as the population ages, and HF continues to be associated with a high mortality rate and frequent need for hospitalization. The total cost of care for patients with HF was $30.7 billion in 2012, and it is estimated to more than double to $69.8 billion by 2030. Given this reality, there has been recent investigation into ways of identifying and preventing HF in patients at risk (stage A HF) and those with cardiac structural and functional abnormalities but no clinical HF symptoms (stage B). For patients who have symptoms of HF (stage C), there has been important research into the most effective ways to decongest patients hospitalized with acute decompensated HF and prevent future hospital readmissions. Successful strategies to treat patients with HF and preserved ejection fraction, which has increased in prevalence, continue to be sought. We are in the midst of a rapid evolution in our ability to care for patients with end-stage HF (stage D) because of the introduction of and improvements in mechanical circulatory support. Left ventricular assist devices used as destination therapy offer an important therapeutic option to patients who do not qualify for heart transplant because of advanced age or excessive comorbidity. This review provides a thorough update on contemporary strategies in the diagnosis and management of HF by stage (A to D) that have emerged during the past several years.

    Lumbar spinal instability (LSI) is a common spinal disorder and can be associated with substantial disability. The concept of defining clinically relevant classifications of disease or 'target condition' is used in diagnostic research. Applying this concept to LSI we hypothesize that a set of clinical and radiological criteria can be developed to identify patients with this target condition who are at high risk of 'irreversible' decompensated LSI for whom surgery becomes the treatment of choice. In LSI, structural deterioration of the lumbar disc initiates a degenerative cascade of segmental instability. Over time, radiographic signs become visible: traction spurs, facet joint degeneration, misalignment, stenosis, olisthesis and de novo scoliosis. Ligaments, joint capsules, local and distant musculature are the functional elements of the lumbar motion segment. Influenced by non-functional factors, these functional elements allow a compensation of degeneration of the motion segment. Compensation may happen on each step of the degenerative cascade but cannot reverse it. However, compensation of LSI may lead to an alleviation or resolution of clinical symptoms. In return, the target condition of decompensation of LSI may cause the new occurrence of symptoms and pain. Functional compensation and decompensation are subject to numerous factors that can change which makes estimation of an individual's long-term prognosis difficult. Compensation and decompensation may influence radiographic signs of degeneration, e.g. the degree of misalignment and segmental angulation caused by LSI is influenced by the tonus of the local musculature. This conceptual model of compensation/decompensation may help solve the debate on functional and psychosocial factors that influence low back pain and to establish a new definition of non-specific low back pain. Individual differences of identical structural disorders could be explained by compensated or decompensated LSI leading to changes

    2015-10-01

    Full Text Available Introduction:Cone-Beam Computed Tomography (CBCT is essential for tridimensional planning of orthognathic surgery, as it allows visualization and evaluation of bone structures and mineralized tissues. Tomographic slices allow evaluation of tooth inclination and individualization of movement performed during preoperative decompensation. The aim of this paper was to assess maxillary and mandibular incisors inclination pre and post orthodontic decompensation in skeletal Class III malocclusion.Methods:The study was conducted on six individuals with skeletal Class III malocclusion, surgically treated, who had Cone-Beam Computed Tomographic scans obtained before and after orthodontic decompensation. On multiplanar reconstruction view, tomographic slices (axial, coronal and sagittal were obtained on the long axis of each incisor. The sagittal slice was used for measurement taking, whereas the references used to assess tooth inclination were the long axis of maxillary teeth in relation to the palatal plane and the long axis of mandibular teeth in relation to the mandibular plane.Results:There was significant variation in the inclination of incisors before and after orthodontic decompensation. This change was of greater magnitude in the mandibular arch, evidencing that natural compensation is more effective in this arch, thereby requiring more intensive decompensation.Conclusion:When routinely performed, the protocols of decompensation treatment in surgical individuals often result in intensive movements, which should be reevaluated, since the extent of movement predisposes to reduction in bone attachment levels and root length.

    Maple syrup urine disease (MSUD) is a defect in the catabolism of the branched-chain amino acids; leucine, isoleucine, and valine. Affected patients may also develop hyperammonaemia of unknown etiology. This report describes a four-year-old girl with MSUD, who presented with decompensated hyperleucinaemia with hyperammonaemia. The oral administration of the N-acetylglutamate analogue, N-carbamylglutamate (NCG), 200 mg/kg/day as a loading dose, and 100 mg/kg/day as a maintenance dose, in combination with standard therapy resulted in a significant decrease of plasma ammonia levels. This observation suggests that NCG may be an important adjunct to standard therapy in the management of decompensated MSUD patients with high leucine and ammonia levels. Supportive evidence from either randomized controlled trials or a large prospective cohort study is needed to confirm this interesting finding.

  18. Role of TIPS in Improving Survival of Patients with Decompensated Liver Disease

    Full Text Available Liver cirrhosis is associated with higher morbidity and reduced survival with appearance of portal hypertension and resultant decompensation. Portal decompression plays a key role in improving survival in these patients. Transjugular intrahepatic portosystemic shunts are known to be efficacious in reducing portal venous pressure and control of complications such as variceal bleeding and ascites. However, they have been associated with significant problems such as poor shunt durability, increased encephalopathy, and unchanged survival when compared with conservative treatment options. The last decade has seen a significant improvement in these complications, with introduction of covered stents, better selection of patients, and clearer understanding of procedural end-points. Use of TIPS early in the period of decompensation also appears promising in further improvement of survival of cirrhotic patients.

  20. Impact of physician specialty on quality care for patients hospitalized with decompensated cirrhosis.

    Directory of Open Access Journals (Sweden)

    Full Text Available Decompensated cirrhosis is a common precipitant for hospitalization, and there is limited information concerning factors that influence the delivery of quality care in cirrhotic inpatients. We sought to determine the relation between physician specialty and inpatient quality care for decompensated cirrhosis.We reviewed 247 hospital admissions for decompensated cirrhosis, managed by hospitalists or intensivists, between 2009 and 2013. The primary outcome was quality care delivery, defined as adherence to all evidence-based specialty society practice guidelines pertaining to each specific complication of cirrhosis. Secondary outcomes included new complications, length-of-stay, and in-hospital death.Overall, 147 admissions (59.5% received quality care. Quality care was given more commonly by intensivists, compared with hospitalists (71.7% vs. 53.1%, P = .006, and specifically for gastrointestinal bleeding (72% vs. 45.8%, P = .03 and hepatic encephalopathy (100% vs. 63%, P = .005. Involvement of gastroenterology consultation was also more common in admissions in which quality care was administered (68.7% vs. 54.0%, P = .023. Timely diagnostic paracentesis was associated with reduced new complications in admissions for refractory ascites (9.5% vs. 46.6%, P = .02, and reduced length-of-stay in admissions for spontaneous bacterial peritonitis (5 days vs. 13 days, P = .02.Adherence to quality indicators for decompensated cirrhosis is suboptimal among hospitalized patients. Although quality care adherence appears to be higher among cirrhotic patients managed by intensivists than by hospitalists, opportunities for improvement exist in both groups. Rational and cost-effective strategies should be sought to achieve this end.

    Twenty patients with impaired left ventricular function during exercise, who underwent major vascular surgery for arteriosclerotic disease, were randomly digitalized in the immediate postoperative period. All patients had a smooth postoperative course. Haemodynamic measurements showed improved left ventricular function in those who received digitalis, since 60 min after full digitalization the digitalized patients had a highly significant decrease in pulmonary capillary wedge pressure (PCWP) with unchanged stroke volume index (SVI) and left ventricular stroke work index (LVSWI). The same improvement in cardiac function was present the next morning. The present study provides haemodynamic data in support of clinical studies showing a beneficial effect of prophylactic digitalization in surgical patients with clinical signs of arteriosclerotic heart disease, though not in overt failure.

    Peripartum cardiomyopathy(PPCM) is a rare but serious form of cardiac failure affecting women in the last month of pregnancy or early puerperium within six months. Clinical presentation of PPCM is similar to that of idiopathic dilated cardiomyopathy, and maternal mortality is high. An 18 year-old primigravida was admitted to our hospital at the end of forty-one weeks of gestation. She was diagnosed with PPCM complicated with heart failure. Preoperative optimization was done with a view to managing left ventricular failure. Continuous epidural anesthesia in the sitting position with lidocaine was used for cesarean section. The baby was delivered successfully. Intravenous furosemide 20 mg, morphine 10 mg, cedilanid 0.4 mg were given. Nitroglycerin and milinone infusions continued throughout the surgery titrated to the hemodynamics. The patient received inotropic agents, dieresis, vasodilators and anticoagulants post-operatively. Both the mother and the baby were discharged safely 9 days after operation.

    Evidence about the clinical effects of entecavir (ETV) for patients with hepatitis B decompensated cirrhosis remain controversial. Therefore, we perform this meta-analysis to assess the treatment outcomes of ETV in participants with hepatitis B decompensated cirrhosis. Relevant studies were identified by searching databases until the March 2016. A random-effects model was used to estimate summary relative risks (RRs) and 95% confidence intervals (CIs). GRADEprofiler3.6 was used to evaluate the quality of the evidence. A total of 26 studies (involving 2040 patients) were included. The quality of the evidence was classified from very low to high by the GRADED approach for all included RCTs. Meta-analysis showed that patients were more likely to experience HBV-DNA loss (RR:1.85, 95%CIs: 1.41 to 2.43, P < 0.0001 at 48 weeks), have normalized alanine aminotransferase levels (ALT) (P = 0.003 at 24 weeks, P = 0.02 at 48 weeks), and have a low mortality rate at 24 weeks (P = 0.003) when treated with ETV. There was no significant different between ETV and the control groups at the total mortality (P = 0.06) and HBeAg seroconversion (P = 0.14). In conclusion, ETV could be the first line therapy for patients with HBV related decompensated cirrhosis, because ETV could reduce the early mortality and move HBV DNA load down.

    Full Text Available Background: Dexamethasone intravitreal implant (DEX largely showed his safety and efficacy for the treatment of cases of macular edema. Even if uncommon, delivery dislocation in anterior chamber has been described in Literaure as complication of the injection procedure, leading to irreversible endothelial cell loss in the majority of cases. We report a case of a 66-year-old man with pain and vision loss in his left eye. The anamnesis revealed a recent intravitreal injection of DEX implant for a persistent cystoid macular edema related to central retinal vein occlusion. Anterior segment examination showed corneal edema and the rod implant adherent to corneal endothelium. A large peripheral iridectomy was evident with retroillumination and IOL appeared good centered in the bag. The implant was removed but corneal decompensation was irreversible. One month later, an endothelial keratoplasty was successfully performed restoring corneal transparency. DEX intravitreal implant can migrate from vitreous cavity to anterior chamber and lead to irreversible corneal decompensation by mechanical and chemical toxicity on corneal endothelium. Removeal of the implant is necessary to avoid total endothelial decompensation. Despite this, in some cases endothelial keratoplasty had to be performed.

    Recently, direct antiviral agents(DAAs) have been increasingly used for the treatment of chronic hepatitis C virus(HCV) infections, replacing interferon-based regimens that have severe adverse effects and low tolerability. The constant supply of new DAAs makes shorter treatment periods with enhanced safety possible. The efficacy of DAAs for treatment of compensated liver cirrhosis(LC) is not less than that for treatment of non-cirrhotic conditions. These clinical advantages have been useful in pre- and post-liver transplantation(LT) settings. Moreover, DAAs can be used to treat decompensated HCV-induced LC in elderly patients or those with severe complications otherwise having poor prognosis. Although encouraging clinical data are beginning to appear, the actual efficacy of DAAs for suppressing disease progression, allowing delisting for LT and, most importantly, improving prognosis of patients with decompensated HCV-LC remains unknown. Casecontrol studies to examine the short- or long-term effects of DAAs for treatment of decompensated HCV-LC are urgently need.

    We used a case-crossover approach to evaluate the association between ambient air pollution and the rate of hospitalization for congestive heart failure (CHF) among Medicare recipients (age ≥ 65) residing in Allegheny County (Pittsburgh area), PA, during 1987–1999. We also explored effect modification by age, gender, and specific secondary diagnoses. During follow-up, there were 55,019 admissions with a primary diagnosis of CHF. We found that particulate matter with aerodynamic diameter ≤ 10 μm (PM10), carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide – but not ozone – were positively and significantly associated with the rate of admission on the same day in single-pollutant models. The strongest associations were observed with CO, NO2 and PM10. The associations with CO and NO2 were the most robust in two-pollutant models, remaining statistically significant even after adjusting for other pollutants. Patients with a recent myocardial infarction were at greater risk of particulate-related admission, but there was otherwise no significant effect modification by age, gender, or other secondary diagnoses. These results suggest that short-term elevations in air pollution from traffic-related sources may trigger acute cardiac decompensation of heart failure patients and that those with certain comorbid conditions may be more susceptible to these effects.

    2013-08-01

    Nearly 700,000 emergency department (ED) visits were due to acute heart failure (AHF) in 2009. Most visits result in a hospital admission and account for the largest proportion of a projected $70 billion to be spent on heart failure care by 2030. ED-based risk prediction tools in AHF rarely impact disposition decision making. This is a major factor contributing to the 80% admission rate for ED patients with AHF, which has remained unchanged over the last several years. Self-care behaviors such as symptom monitoring, medication taking, dietary adherence, and exercise have been associated with decreased hospital readmissions, yet self-care remains largely unaddressed in ED patients with AHF and thus represents a significant lost opportunity to improve patient care and decrease ED visits and hospitalizations. Furthermore, shared decision making encourages collaborative interaction between patients, caregivers, and providers to drive a care path based on mutual agreement. The observation that “difficult decisions now will simplify difficult decisions later” has particular relevance to the ED, given this is the venue for many such issues. We hypothesize patients as complex and heterogeneous as ED patients with AHF may need both an objective evaluation of physiologic risk as well as an evaluation of barriers to ideal self-care, along with strategies to overcome these barriers. Combining physician gestalt, physiologic risk prediction instruments, an evaluation of self-care, and an information exchange between patient and provider using shared decision making may provide the critical inertia necessary to discharge patients home after a brief ED evaluation.

    2014-01-01

    Introduction. Acute heart failure (AHF) is associated with a higher risk for the occurrence of rehospitalization and death. Galectin-3 (GAL3) is elevated in AHF patients and is an indicator in predicting short-term mortality. The total body water using bioimpedance vector analysis (BIVA) is able to identify mortality within AHF patients. The aim of this study was to evaluate the short- and long-term predictive value of GAL3, BIVA, and the combination of both in AHF patients in Emergency Department (ED). Methods. 205 ED patients with AHF were evaluated by testing for B type natriuretic peptide (BNP) and GAL3. The primary endpoint was death and rehospitalization at 30, 60, 90, and 180 days and 12 and 18 months. AHF patients were evaluated at the moment of ED arrival with clinical judgment and GAL3 and BIVA measurement. Results. GAL3 level was significantly higher in patients >71 years old, and with eGFR 17.8 ng/mL shows significant survival difference. At multivariate Cox regression analysis GAL3 is an independent variable to predict death + rehospitalization with a value of 32.24 ng/mL at 30 days (P < 0.005). Conclusion. In patients admitted for AHF an early assessment of GAL3 and BIVA seems to be useful in identifying patients at high risk for death and rehospitalization at short and long term. Combining the biomarker and the device could be of great utility since they monitor the severity of two pathophysiological different mechanisms: heart fibrosis and fluid overload. PMID:25101304

    2012-11-01

    Beta-blockers remain a cornerstone of therapy in the management of acute coronary syndrome (ACS). The 2007 American College of Cardiology/American Heart Association unstable angina/non-ST elevation myocardial infarction guideline revisions recommend a target heart rate (HR) of 50-60 beats per minute (bpm). Despite improved trends toward utilization of beta-blockers therapy, beta-blockers continue to be underdosed. Guideline-based tools have been shown to improve adherence to evidence-based therapy in patients with ACS. Implementation of a standardized ACS pathway would lead to titration of beta-blockers to recommended dosages with improved HRs in eligible patients. The ACS clinical protocol was implemented at the University of Toledo Medical Center in May 2007. A retrospective study of 516 patients admitted during a comparable 6-month period, before and after the institution of the protocol, was conducted. The preprotocol and protocol group included 237 and 279 patients, respectively. Patient information extracted from the medical records included age, gender, HR on admission, blood pressure on admission, duration of hospital stay, preadmission use of beta-blocker, type of beta-blocker and dosage, discharge beta-blocker and dosage, peak troponin levels, and therapeutic intervention. A target HR of less than 60 bpm was achieved in 19% of the protocol group, as compared with 6% in the preprotocol group (P metoprolol in the protocol group was noted to be significantly higher (118 vs. 80 mg/d; P < 0.001). The institution of an ACS clinical pathway led to utilization of beta-blockers in significantly higher dosages, resulting in improved HR control and increased attainment of target HR.

    Patients with pulmonary hypertension associated with congenital heart disease survive longer with preserved right ventricular (RV) function compared with those with primary pulmonary hypertension. The purpose of this study was to test the hypothesis that superior RV performance can be demonstrated, at baseline and when challenged with increased RV afterload, in lambs with chronic left-to-right cardiac shunts compared with control lambs. A shunt was placed between the pulmonary artery and the aorta in fetal lambs (shunt). RV pressure-volume loops were obtained 4 wk after delivery in shunt and control lambs, before and after increased afterload was applied using pulmonary artery banding (PAB). Baseline stroke volume (8.7 ± 1.8 vs. 15.8 ± 2.7 ml, P = 0.04) and cardiac index (73.0 ± 4.0 vs. 159.2 ± 25.1 ml·min(-1)·kg(-1), P = 0.02) were greater in shunts. After PAB, there was no difference in the change in cardiac index (relative to baseline) between groups; however, heart rate (HR) was greater in controls (168 ± 7.3 vs. 138 ± 6.6 beats/min, P = 0.01), and end-systolic elastance (Ees) was greater in shunts (2.63 vs. 1.31 × baseline, P = 0.02). Control lambs showed decreased mechanical efficiency (71% baseline) compared with shunts. With acute afterload challenge, both controls and shunts maintained cardiac output; however, this was via maladaptive responses in controls, while shunts maintained mechanical efficiency and increased contractility via a proposed enhanced Anrep effect-the second, slow inotropic response in the biphasic ventricular response to increased afterload, a novel finding in the RV. The mechanisms related to these physiological differences may have important therapeutic implications.

    Full Text Available BACKGROUND: Congestive physical findings such as pulmonary rales and third heart sound (S3 are hallmarks of acute heart failure (AHF. However, their role in outcome prediction remains unclear. We sought to investigate the association between congestive physical findings upon admission, steady-state biomarkers at the time of discharge, and long-term outcomes in AHF patients. METHODS: We analyzed the data of 133 consecutive AHF patients with an established diagnosis of ischemic or non-ischemic (dilated or hypertrophic cardiomyopathy, admitted to a single-center university hospital between 2006 and 2010. The treating physician prospectively recorded major symptoms and congestive physical findings of AHF: paroxysmal nocturnal dyspnea, orthopnea, pulmonary rales, jugular venous distension (JVD, S3, and edema. The primary endpoint was defined as rehospitalization for HF. RESULTS: Majority (63.9% of the patients had non-ischemic etiology and, at the time of admission, S3 was seen in 69.9% of the patients, JVD in 54.1%, and pulmonary rales in 43.6%. The mean follow-up period was 726 ± 31 days. Patients with pulmonary rales (p < 0.001 and S3 (p  =  0.011 had worse readmission rates than those without these findings; the presence of these findings was also associated with elevated troponin T (TnT levels at the time of discharge (odds ratio [OR] 2.8; p  =  0.02 and OR 2.6; p  =  0.05, respectively. CONCLUSION: Pulmonary rales and S3 were associated with inferior readmission rates and elevated TnT levels on discharge. The worsening of the readmission rate owing to congestive physical findings may be a consequence of on-going myocardial injury.

    Introduction Measurement of mortality in patients with acute myocardial infarction (AMI), congestive heart failure (CHF) and pneumonia (PN) is a high priority since these are common reasons for hospitalization. However, mortality in patients with inflammatory bowel disease (IBD) that are hospitalized for these common medical conditions is unknown. Methods A retrospective review of the 2005–2011 National Inpatient Sample (NIS), (approximately a 20% sample of discharges from community hospitals) was performed. A dataset for all patients with ICD-9-CM codes for primary diagnosis of acute myocardial infarction, pneumonia or congestive heart failure with a co-diagnosis of IBD, Crohn’s disease (CD) or ulcerative colitis (UC). 1:3 propensity score matching between patients with co-diagnosed disease vs. controls was performed. Continuous variables were compared between IBD and controls. Categorical variables were reported as frequency (percentage) and analyzed by Chi-square tests or Fisher’s exact test for co-diagnosed disease vs. control comparisons. Propensity scores were computed through multivariable logistic regression accounting for demographic and hospital factors. In-hospital mortality between the groups was compared. Results Patients with IBD, CD and UC had improved survival after AMI compared to controls. 94/2280 (4.1%) of patients with IBD and AMI died, compared to 251/5460 (5.5%) of controls, p = 0.01. This represents a 25% improved survival in IBD patients that were hospitalized with AMI. There was a 34% improved survival in patients with CD and AMI. There was a trend toward worsening survival in patients with IBD and CHF. Patients with CD and PN had improved survival compared to controls. 87/3362 (2.59%) patients with CD and PN died, compared to 428/10076 (4.25%) of controls, p < .0001. This represents a 39% improved survival in patients with CD that are hospitalized for PN. Conclusion IBD confers a survival benefit for patients hospitalized with AMI. A

We determined the characteristics of hospitalized AHF patients who experienced no worsening renal function (non-WRF, WRFt, or WRFp, and the relationship between cohorts and AHF-related outcomes. Methods and results: A patient’s first AHF hospitalization (index was identified in the Cerner Health Facts® database (January 2008-March 2011. Patients had WRF if serum creatinine (SCr was ≥0.3 mg/dL and increased ≥25% from baseline, and they were designated as WRFp if present at discharge or WRFt if not present at discharge. A total of 55,436 patients were selected (non-WRF =77%, WRFp =10%, WRFt =13%. WRFp had greater comorbidity burden than WRFt. At index hospitalization, WRFp patients had the highest mortality, whereas WRFt patients had the longest length of stay (LOS and highest costs. These trends were observed at 30, 180, and 365 days postdischarge and confirmed by multivariable analyses. WRF patients had more AHF-related readmissions than non-WRF patients. In sensitivity analyses of the patient subset with live index hospitalization discharges, postdischarge LOS and costs were highest in WRFt patients, whereas mortality associated with a HF hospitalization was significantly higher for WRF patients vs non-WRF patients, with no difference between WRFp and WRFt. Conclusion: In patients hospitalized for AHF, WRFp was associated with the highest mortality, whereas WRFt was associated with the highest LOS and costs. WRF patients had higher readmissions than non

    The clinical benefit of thrombus aspiration (TA) in patients presenting with acute ST-elevation myocardial infarction (STEMI) and treated with primary percutaneous coronary intervention (PCI) is not well defined. Furthermore, there is a large variation in the use of TA in real-world registries. Between 2005 and 2008, a total of 7146 consecutive patients with acute STEMI undergoing primary PCI were prospectively enrolled into the PCI Registry of the Euro Heart Survey Programme. For the present analysis, patients treated additionally with TA (n = 897, 12.6 %) were compared with those without TA (n = 6249, 87.4 %). Patients with hemodynamic instability at initial presentation (15.1 vs. 11.0 %; p < 0.001) and resuscitation prior to PCI (10.4 vs. 7.4 %; p = 0.002) were more frequently treated with TA. TIMI flow grade 0/1 before PCI was more often found among those with TA (73.5 vs. 58.6 %; p < 0.001). After adjustment for confounding factors in the propensity score analysis, TA was not associated with improved in-hospital survival (risk difference -1.1 %, 95 % confidence interval -2.7 to 0.6 %). In this European real-world registry, the rate of TA use was low. Hemodynamically unstable patients were more likely to be treated with TA. Consistent with the results of the TASTE study and the TOTAL trial, TA was not associated with a significant reduction in short-term mortality.

    Background Results from the Diuretic Optimization Strategies in Acute Heart Failure (DOSE-AHF) study suggest that an initial continuous infusion of loop diuretics is not superior to bolus dosing with regard to clinical endpoints in AHF. We hypothesized that outpatient furosemide dose was associated with congestion and poorer renal function, and explored the hypothesis that a continuous infusion may be more effective in patients on higher outpatient diuretic doses. Methods DOSE-AHF randomized 308 patients within 24 hours of admission to high vs. low initial intravenous diuretic dose given as either a continuous infusion or bolus. We compared baseline characteristics and assessed associations between mode of administration (bolus vs. continuous) and outcomes in patients receiving high-dose (≥120 mg furosemide equivalent, n=177) versus low-dose (<120 mg furosemide equivalent, n=131) outpatient diuretics. Results Patients on higher doses of furosemide were less frequently on renin-angiotensin system inhibitors (P=.01), and had worse renal function and more advanced symptoms. There was a significant interaction between outpatient dose and mode of therapy (P=0.01) with respect to net fluid loss at 72 hours after adjusting for creatinine and intensification strategy. Admission diuretic dose was associated with an increased risk of death or rehospitalization at 60 days (adjusted HR=1.08 per 20-mg increment in dose, 95% CI 1.01–1.16, P=.03). Conclusions In acute HF, patients on higher diuretic doses have greater disease severity, and may benefit from an initial bolus strategy. PMID:23194486

    Full Text Available Abstract Background Ischaemic heart disease is a global priority of health-care policy, because of its social repercussions and its impact on the health-care system. Yet there is little information on coronary morbidity in Spain and on the effect of the principal risk factors on risk of coronary heart disease. The objective of this study is to describe the epidemiology of coronary disease (incidence, mortality and its association with cardiovascular risk factors using the information gathered by primary care practitioners on cardiovascular health of their population. Methods A prospective study was designed. Eight primary-care centres participated, each contributing to the constitution of the cohort with the entire population covered by the centre. A total of 6124 men and women aged over 25 years and free of cardiovascular disease agreed to participate and were thus enrolled and followed-up, with all fatal and non-fatal coronary disease episodes being registered during a 5-year period. Repeated measurements were collected on smoking, blood pressure, weight and height, serum total cholesterol, high-density and low-density lipoproteins and fasting glucose. Rates were calculated for acute myocardial infarction and ischaemic heart disease. Associations between cardiovascular risk factors and coronary disease-free survival were evaluated using Kaplan-Meier and Cox regression analyses. Results Mean age at recruitment was 51.6 ± 15, with 24% of patients being over 65. At baseline, 74% of patients were overweight, serum cholesterol over 240 was present in 35% of patients, arterial hypertension in 37%, and basal glucose over 126 in 11%. Thirty-four percent of men and 13% of women were current smokers. During follow-up, 155 first episodes of coronary disease were detected, which yielded age-adjusted rates of 362 and 191 per 100,000 person-years in men and women respectively. Disease-free survival was associated with all risk factors in univariate

    The aim of this study was to assess the prevalence of free-floating thrombi in the right heart (FFT) and the accuracy of computed tomography (CT) for their detection in pulmonary embolism (PE). We studied 340 consecutive patients presenting with PE. All patients underwent CT and echocardiography. The prevalence of FFT was 3.5% in the global population of PE and 22% in high-risk PE. Dyspnoea, cardiogenic shock, cardiac arrest and tachycardia were more frequently found in patients with FFT (p = 0.04, p < 0.0001, p = 0.0003 and p = 0.01, respectively). Sensitivity and specificity of CT for the detection of FFT were 100% (95% confidence interval: 74%-100%) and 97% (95%-99%), whereas positive and negative predictive values were 57% (34%-78%) and 100% (99%-100%). Among patients with FFT, right ventricular dilation was always detected by CT, whereas no right ventricular dilation was found among patients with a false diagnosis of FFT performed by CT (p < 0.0001). Prevalence of FFT is 3.5% and differs according to the clinical presentation. Detection of FFT by CT is feasible and should lead to echocardiography being promptly performed for the confirmation of FFT. (orig.)

    The acute immobilized stress was studied for its effect on oxidation rate of [1-14C]palmitoyl-CoA, [1-14C]acetyl-CoA and [2-14C]pyruvate in mitochondria of the adrenals, liver and heart of rabbits. The stress effect on the energy metabolism of adrenals is associated with an increase of the rate of CO2 formation from pyruvate and with a decrease of the rate of CO2 formation from palmitoyl-CoA. Intensified oxidation of all substrates is observed in the heart mitochondria. The processes of beta-oxidation are more active in the liver. The data obtained evidence for differences in the mechanisms of energy metabolism reconstruction under acute stress in tissues with different functional specialization.

    Background: Renal function is associated with mortality and functional disabilities in stroke patients, and impaired autonomic function is common in stroke, but little is known regarding its effects on stroke patients with renal dysfunction. This study sought to evaluate the association between autonomic function and stroke in patients with renal dysfunction. Methods: This study comprised 232 patients with acute ischemic stroke consecutively enrolled from February 2013 to November 2014 at Guangdong Provincial Hospital of Chinese Medicine in China. All patients recruited underwent laboratory evaluation and 24 h Holter electrocardiography (ECG). Autonomic function was measured based on the heart rate variability (HRV) using 24 h Holter ECG. Renal damage was assessed through the estimated glomerular filtration rate (eGFR), and stroke severity was rated according to the National Institutes of Health Stroke Scale (NIHSS). The Barthel index and modified Rankin score were also determined following admission. All the clinical covariates that could potentially affect autonomic outcome variables were adjusted with linear regression. Results: In the patients with a mild or moderate decreased eGFR, the values for the standard deviation of the averaged normal-to-normal RR interval (SDANN) index (P = 0.022), very low frequency (VLF) (P = 0.043), low frequency (LF) (P = 0.023), and ratio of low-to-high frequency power (LF/HF) (P = 0.001) were significantly lower than those in the patients with a normal eGFR. A multinomial linear regression indicated that eGFR (t = 2.47, P = 0.014), gender (t = −3.60, P < 0.001), and a history of hypertension (t = −2.65, P = 0.008) were the risk factors of LF/HF; the NIHSS score (SDANN index: t = −3.83, P < 0.001; VLF: t = −3.07, P = 0.002; LF: t = −2.79, P = 0.006) and a history of diabetes (SDANN index: t = −3.58, P < 0.001; VLF: t = −2.54, P = 0.012; LF: t = −2.87, P = 0.004) were independent factors for the SDANN index, VLF

    Three priority areas in the prevention, diagnosis and management of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) were identified and discussed in detail: 1. Echocardiography and screening/diagnosis of RHD – Given the existing uncertainty it remains premature to advocate for or to incorporate echocardiographic screening for RHD into Australian clinical practice. Further research is currently being undertaken to evaluate the potential for echocardiography screening. 2. Secondary prophylaxis – Secondary prophylaxis (long acting benzathine penicillin injections) must be seen as a priority. Systems-based approaches are necessary with a focus on the development and evaluation of primary health care-based or led strategies incorporating effective health information management systems. Better/novel systems of delivery of prophylactic medications should be investigated. 3. Management of advanced RHD – National centres of excellence for the diagnosis, assessment and surgical management of RHD are required. Early referral for surgical input is necessary with multidisciplinary care and team-based decision making that includes patient, family, and local health providers. There is a need for a national RHD surgical register and research strategy for the assessment, intervention and long-term outcome of surgery and other interventions for RHD.

    Scarce data exist on the relationship of C-reactive protein (CRP) or plasminogen activator inhibitor-1 (PAI-1) to the occurrence of heart failure (HF) or cardiogenic shock (CS) after acute myocardial infarction (AMI) and on the relationship between these biomarkers and mortality in CS patients. Thus, we compared high-sensitivity CRP and PAI-1 antigen plasma levels on admission among 3 age- and gender-matched AMI patients groups (consisting of 60 patients with CS, 60 with HF, and 60 without HF on admission), after determining that PAI-1 levels did not vary significantly diurnally in these groups by comparing the data among subgroups which were divided according to admission time within the groups. For CS patients, we also conducted regression analyses to examine the relations of these biomarkers to mortality. CRP levels both in CS (P 0.01), and CRP and PAI-1 were independent predictors of in-hospital (Odds ratio [OR] = 6.12, 95% confidence intervals [95%CI] = 1.47-25.54 and OR = 5.92, 95%CI = 1.31-26.77, respectively) and 1-year mortality (OR = 5.53, 95%CI = 1.21-25.17 and OR = 5.48, 95%CI = 1.09-27.52, respectively) in CS patients. In conclusion, at admission, CRP is associated with the occurrence of CS and HF and PAI-1 is associated with the occurrence of CS after AMI, and they are of prognostic value in CS complicating AMI.

    Full Text Available BACKGROUND AND AIMS: In patients with advanced liver cirrhosis due to chronic hepatitis C virus (HCV infection antiviral therapy with peginterferon and ribavirin is feasible in selected cases only due to potentially life-threatening side effects. However, predictive factors associated with hepatic decompensation during antiviral therapy are poorly defined. METHODS: In a retrospective cohort study, 68 patients with HCV-associated liver cirrhosis (mean MELD score 9.18 ± 2.72 were treated with peginterferon and ribavirin. Clinical events indicating hepatic decompensation (onset of ascites, hepatic encephalopathy, upper gastrointestinal bleeding, hospitalization as well as laboratory data were recorded at baseline and during a follow up period of 72 weeks after initiation of antiviral therapy. To monitor long term sequelae of end stage liver disease an extended follow up for HCC development, transplantation and death was applied (240 weeks, ± SD 136 weeks. RESULTS: Eighteen patients (26.5% achieved a sustained virologic response. During the observational period a hepatic decompensation was observed in 36.8%. Patients with hepatic decompensation had higher MELD scores (10.84 vs. 8.23, p14, respectively. Baseline MELD score was significantly associated with the risk for transplantation/death (p<0.001. CONCLUSIONS: Our data suggest that the baseline MELD score predicts the risk of hepatic decompensation during antiviral therapy and thus contributes to decision making when antiviral therapy is discussed in HCV patients with advanced liver cirrhosis.

    目的:对比左西孟旦(Levo)和重组人脑利钠肽(rhBNP)治疗急性失代偿性心力衰竭(ADHF)的效果。方法选取75例ADHF患者,随机均分入实验组(Levo组、rhBNP组)及对照组(多巴酚丁胺组)。观察并比较3组患者用药72 h后心率、呼吸频率、24 h尿量、6分钟步行距离改善情况及用药1周后血浆脑利钠肽(NT-proBNP)、左室舒张末期内径(LVEDD)以及左室射血分数(LVEF)变化情况。结果用药72 h后各组心率及呼吸频率均降低、24 h尿量及6分钟步行距离均增加(P0.05);治疗后,Levo组与rhBNP组上述指标改善程度较多巴酚丁胺组更明显(P0.05), but the LVEDD was improved barely (P>0.05). The improvements were more significant in Levo group and rhBNP group compared to those of control group (P<0.05). There were no significant differenc⁃es in improvements between Levo group and rhBNP group. The common adverse reactions were hypotension and ventricular premature beats. There were no significant differences in adverse event rates between three groups (P<0.05). Conclusion As compared with dobutamine, Levo and rhBNP have optimized efficacy, fewer side effects and good safety in the treatment of ADHF. They are worth of clinical application.

    Full Text Available Abstract Background Nitric oxide (NO is an endothelium derived relaxing factor (EDRF which has an important role for regulating the heart-vessel physiology. The objective of this study was to evaluate the effects of the eNOS T-786C polymorphism on lipid parameters and the development of acute coronary syndrome (ACS and coronary heart disease (CHD for the first time in a Turkish study group. We have analyzed the genotype frequencies of the T-786C polymorphism of the eNOS gene in 10 ACS patients (5 men, 5 women, 20 CHD patients (14 men, 6 women, and 31 controls (10 men, 21 women, who were angiographically proven to have normal coronaries. Results The demographic, biochemical and left ventricule systolic dysfunction data of the ACS, CHD patients and controls were analyzed as a function of eNOS T-786C genotypes. The eNOS gene T-786C polymorphism frequencies for T/T, C/T and C/C genotypes were respectively 10%, 40%, 50% in subjects with ACS; 75%, 20%, 5% in subjects with CHD and 67.7%, 25.8%, 6.5% in the control group. Significant difference was observed in genotype frequencies between the study groups for T-786C polymorphism (p = 0.001. The CC genotype frequency was found to be the most prevalent in ACS group in comparison to CHD and control groups (p = 0.001. TT was the most frequently observed genotype in both CHD patients and controls (p = 0.001. Left ventricule systolic dysfunction frequency was found to be highest in C/T genotype carriers (66.7% in patients (ACS+CHD. None of the patients with LVSD were carrying the normal genotype (T/T. The eNOS T-786C polymorphism was not found to be effective over any analyzed lipid variable in patients (ACS+CHD. The HDL-cholesterol levels were found to be lower in CHD group were compared to controls (p Conclusion The significantly high frequency of eNOS -786C/C genotype in ACS patients than in those of controls, indicate the genotype association with ACS. The finding of significantly high frequency of T

    Background Urolithiasis is a common urinary tract disease worldwide. It has been connected to systemic diseases, including hypertension, diabetes mellitus, metabolic syndrome, and cardiovascular disease. In the current study, we aimed to evaluate the relationship between urolithiasis and the complications of acute myocardial infarction (AMI). Materials and methods Data were obtained from the Longitudinal Health Insurance Database 2005 of the National Health Insurance Research Database. All AMI cases, both those who were hospitalized and those who were treated in the emergency department, were identified using the International Classification of Diseases, ninth revision, Clinical Modification (ICD-9-CM) code. Results A total of 37,052 patients with urinary calculi and 148,209 control subjects were enrolled in this study. The average follow-up period was 9.51 years. The risk of AMI was higher among patients with urolithiasis (adjusted hazard ratio [aHR] 1.07, 95% confidence interval [95% CI] 1.03–1.13). We detected a significant association between urolithiasis and intubation (aHR 1.53, 95% CI 1.36–1.73), intensive care unit treatment (aHR 1.22, 95% CI 1.13–1.32), heart failure (aHR 1.59, 95% CI 1.42–1.78), shock (aHR 1.53, 95% CI 1.32–1.77), and arrhythmias (aHR 1.18, 95% CI 1.06–1.33). Furthermore, certain medical treatments for urolithiasis were found to be related to myocardial infarction (MI). Nonsteroidal anti-inflammatory drugs (NSAIDs) were significantly associated with a high risk of AMI. In contrast, allopurinol, thiazide diuretic, potassium-sparing diuretics, and α-blockers have negative association with AMI. Conclusion Urolithiasis had a significantly increased risk of endotracheal intubation and heart failure following AMI. In addition, urolithiasis was also associated with a high risk of intensive care unit treatment,
