    The aim of the present study was to explore the association of health insurance status on the provision of guideline-advocated acute coronary syndrome (ACS) care in Australia. Consecutive hospitalisations of suspected ACS from 14 to 27 May 2012 enrolled in the Snapshot study of Australian and New Zealand patients were evaluated. Descriptive and logistic regression analysis was performed to evaluate the association of patient risk and insurance status with the receipt of care. In all, 3391 patients with suspected ACS from 247 hospitals (23 private) were enrolled in the present study. One-third of patients declared private insurance coverage; of these, 27.9% (304/1088) presented to private facilities. Compared with public patients, privately insured patients were more likely to undergo in-patient echocardiography and receive early angiography; furthermore, in those with a discharge diagnosis of ACS, there was a higher rate of revascularisation (P fee-for-service. In contrast, proportionately fewer privately insured ACS patients were discharged on selected guideline therapies and were referred to a secondary prevention program (P = 0.056), neither of which directly attracts a fee. Typically, as GRACE (the Global Registry of Acute Coronary Events) risk score rose, so did the level of ACS care; however, propensity-adjusted analyses showed lower in-hospital adverse events among the insured group (odds ratio 0.68; 95% confidence interval 0.52-0.88; P = 0.004). Fee-for-service reimbursement may explain differences in the provision of selected guideline-advocated components of ACS care between privately insured and public patients.

    Full Text Available Introduction. The acute coronary syndrome (ACS is a complex disease where genetic and environmental factors are involved. E-selectin gene is a candidate for ACS progression due to its contribution in the inflammatory process and endothelial function. The rs5361 (561A>C polymorphism in the E-selectin gene has been linked to changes in gene expression, affinity for its receptor, and plasmatic levels; therefore it is associated with an increased risk of cardiovascular disease. The aim of this study was to determine the association of the rs5361 polymorphism with ACS and to measure serum levels of soluble E-selectin (sE-selectin. Materials and Methods. 283 ACS patients and 205 healthy subjects (HS from Western Mexico were included. The polymerase chain reaction-restriction fragment length polymorphism was used to determine the rs5361 polymorphism. The sE-selectin levels were measured by enzyme-linked immunosorbent assay. Results. Neither genotype nor allele frequencies of the rs5361 polymorphism showed statistical differences between groups. The sE-selectin levels were significantly higher in ACS patients compared to HS (54.58 versus 40.41 ng/ml, P=0.02. The C allele had no effect on sE-selectin levels. Conclusions. The rs5361 E-selectin gene polymorphism is not a susceptibility marker for ACS in Western Mexico population. However, sE-selectin may be a biological marker of ACS.

    To evaluate the potential differences in risk factors' profile for in-hospital mortality and up to 1-year prognosis, between younger and older patients with first acute coronary syndromes (ACS). From October 2003 to September 2004, 1323 patients with first ACS event from 6 urban and rural Greek hospitals were enrolled into the study, classified as those period of 6-months, the event-rate was higher among the younger patients (p < 0.001). Current smoking was associated with increased risk of 1-month recurrent events, in patients < 65 years (p < 0.05). Myocardial infarction and history of diabetes were associated with increased risk in older patients (p < 0.1). Age-specific identification of the risk factors for recurrent events may have important clinical and public health implications and lead to the development of more effective risk reduction strategies.

    The psychometric properties of the Rosenberg Self-Esteem Scale (RSES) as a clinical research instrument for acute coronary syndrome (ACS) patients were investigated in a translated Chinese version of the instrument. A confirmatory factor analysis was conducted on the RSES to establish its psychometric properties in 128 ACS patients over two observation points (within 1 week and 6 months post-admission for ACS). Internal and test-retest reliability of the RSES-TOT (all-items) and RSES-POS sub-scale (positively valenced items) were found to be acceptable. The RSES-NEG sub-scale (negatively valenced items) lacked acceptable internal reliability. The underlying factor structure of the RSES comprised two distinct but related factors, though there was inconsistency in best model fit indices at the 1-week observation point. The use of the RSES as two sub-scales (RSES-POS and RSES-NEG) may be clinically useful in evaluating the influence of this important psychological construct on the health outcomes of patients with ACS. Directions for future research are indicated.

    In Qatar, ACS (Acute Coronary Syndrome) has become the leading cause of morbidity and mortality. Guidelines recommend that ACS patients should receive indefinite treatment with antiplatelets, β-blockers, angiotensin converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) and statins. The study objectives were to assess the use of evidence-based secondary prevention medication at discharge among ACS patients in Qatar and to determine the clinical and demographic characteristics associated with the use of these medications. A retrospective medical record review was conducted at the Heart Hospital in Qatar. A random sample of 1068 ACS patients was selected. Patient characteristics were summarized. Prevalence of medications at discharge were computed for each medication as well as for medication combinations. Multiple logistic regression was used to detect patient variables that were associated with the outcomes. A p≤0.05 was considered significant. -Percentage of ACS patients discharged on each of the following medications: antiplatelets (aspirin, clopidogrel), β-blockers, ACEI or ARBs and statins and on the combination of these medications-Association between the use of these medications and patient characteristics. In total, 1064 records were reviewed. The majority were males (85.3%) and about 1 in 5 (18.7%) were Qatari. At discharge, patients were prescribed the following: aspirin (96.0%), clopidogrel (92.0%), β-blockers (90.6%) and statins (97.7%). ACEI and ARBs were prescribed to 63.5 and 11.3%, respectively. The concurrent 4 medications (aspirin or clopidogrel, statins or other lowering cholesterol medication, β-blockers and ACEI or ARB) were prescribed to 773 patients (77.8%; 95% confidence interval: 75.2-80.4%). Being overweight or obese, and having PCI (percutaneous coronary intervention) or hypertension were associated with higher prescription of the concurrent medications. Those with diabetes had a 52% increase in the odds of

    Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

    Churg-Strauss Syndrome (CSS) is a rare vasculitis with multiorgan involvement. Cardiac manifestations are common causing serious complications. We report a case of CSS masquerading as a non-ST elevation myocardial infarction with heart failure. CSS should be considered in the differential diagnosis of an acute coronary syndrome(ACS)with normal coronary arteries when history of asthma, peripheral eosinophilia and multisystemic involvement is present.

    The spectrum of acute coronary syndrome (ACS) including unstable angina, non-ST-elevation myocardial infarction and ST-elevation myocardial infarction accounts for increasing numbers of deaths among persons age > or = 65 years in the US. This is important given demographic changes involving falling birth rates and increasing life expectancy. Elderly patients are likely to benefit the most from treatment of ACS, even though community practice still demonstrates less use of cardiac medications as an early-invasive approach among this population.

    The objective of this study was to determine if the extent of quantitative troponin elevation predicted mortality as well as in-hospital complications of cardiac arrest, new heart failure and cardiogenic shock. 16,318 patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) from the Global Registry of Acute Coronary Events (GRACE) were included. The maximum 24 h troponin value as a multiple of the local laboratory upper limit of normal was used. The population was divided into five groups based on the degree of troponin elevation, and outcomes were compared. An adjusted analysis was performed using quantitative troponin as a continuous variable with adjustment for known prognostic variables. For each approximate 10-fold increase in the troponin ratio, there was an associated increase in cardiac arrest, sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) (1.0, 2.4, 3.4, 5.9 and 13.4%; p<0.001 for linear trend), cardiogenic shock (0.5, 1.4, 2.0, 4.4 and 12.7%; p<0.001), new heart failure (2.5, 5.1, 7.4, 11.6 and 15.8%; p<0.001) and mortality (0.8, 2.2, 3.0, 5.3 and 14.0%; p<0.001). These findings were replicated using the troponin ratio as a continuous variable and adjusting for covariates (cardiac arrest, sustained VT or VF, OR 1.56, 95% CI 1.39 to 1.74; cardiogenic shock, OR 1.87, 95% CI 1.61 to 2.18; and new heart failure, OR 1.57, 95% CI 1.45 to 1.71). The degree of troponin elevation was predictive of early mortality (HR 1.61, 95% CI 1.44 to 1.81; p<0.001 for days 0-14) and longer term mortality (HR 1.18, 95% CI 1.07 to 1.30, p=0.001 for days 15-180). The extent of troponin elevation is an independent predictor of morbidity and mortality.

    Nuclear myocardial perfusion imaging is very effective in the evaluation of patients with suspicious acute coronary syndrome (ACS), for adequate diagnosis and treatment. There have been many clinical evidences to support the efficacy and cost-effectiveness. In addition, many authoritative guidelines support the utility of myocardial perfusion imaging in ACS with an appropriate diagnostic protocol. However, with the development of other cardiac imaging modalities, the choice of modality for the diagnosis of suspicious ACS now depends on the availability of each modality in each institute. Newly developed imaging technologies, especially including molecular imaging, are expected to have great potential not only for diagnosis but also for primary, secondary, and tertiary prevention of ACS.

    Patients with acute coronary syndrome (ACS) frequently have vulnerable plaques in the remote coronary arteries, suggesting that ACS is part of the pan-coronary process. In the present study the computed tomography (CT) plaque density in non-culprit atherosclerotic coronary artery lesions was evaluated by multi-slice computed tomography (MSCT) in patients with ACS and non-ACS. MSCT was performed in 21 patients with ACS and 53 patients with non-ACS: 16 of the 21 ACS patients (76%) and 30 of the non-ACS 53 patients (57%) had non-calcified plaques in the non-culprit coronary arteries (p=0.18). CT-low-density plaques (CT density <68 Hounsfield units (HU)) were more frequent in the ACS group (13/16 patients, 81%) than in the non-ACS group (13/30 patients, 43%, p=0.03). In addition, the CT density of the non-culprit lesion was significantly lower in patients with ACS than in those with non-ACS (44.1±22.9 and 77.3±33.7 HU, respectively). Patients with ACS more frequently had CT-low-density plaques in the non-culprit, remote arteries than those with non-ACS, which suggests that ACS treatment should focus not only on stabilizing the culprit lesion but also on systemic stabilization of non-culprit lesions.

    2015-10-01

    Diagnosing acute coronary syndrome (ACS) in the emergency department is often a complex process. Inflammatory markers might be useful for the rapid assessment of a patient's overall risk and might also help predict future episodes. The clinical use of these biomarkers could potentially lower the number of emergency visits and help in the prevention of future adverse events. The aim of this review was to evaluate the clinical utility of markers of cardiovascular inflammation in emergency patients with ACS. Based on a critical analysis of a selection of the literature, we concluded that none of the biomarkers of cardiovascular inflammation would at present be useful for stratifying risk in emergency situations, aiding prognosis, or guiding therapy for patients with ACS.

    Background: To investigate clinical outcomes of percutaneous coronary intervention using a sirolimus-eluting stent with bioresorbable polymer, Ultimaster (BP-SES) compared with a permanent polymer everolimus-eluting stent, Xience (PP-EES) in patients with high risk (ST-segment elevation and non-ST-segment elevation myocardial infarction) acute coronary syndromes (ACS) enrolled in the CENTURY II trial. Methods: CENTURY II is a prospective, multicenter, randomized, single blind, controlled trial comparing BP-SES and PP-EES, with primary endpoint of target lesion failure (TLF) at 9 month post-stent implantation. Out of 1123 patients enrolled in CENTURY II trial, 264 high risk ACS patients were included in this subgroup analysis, and the clinical outcomes including target lesion failure (TLF), target vessel failure (TVF), cardiac death, myocardial infarction, and stent thrombosis were evaluated at 24 months. Results: The baseline clinical, angiographic and procedural characteristics were similar between two groups. At 24 months, TLF occurred in 6.3% of patients receiving a BP-SES and 6.5% of patients receiving a PP-EES (P = 0.95); TVF was 6.3% in patients receiving a BP-SES and 9.4% in patients receiving a PP-EES (P = 0.36). There were no significant differences in cardiac death, myocardial infarction and stent thrombosis rate. Conclusions: BP-SES achieved similar safety and efficacy outcomes as PP-EES in this ACS subgroup of CENTURY II study, at 24-month follow-up. This finding is hypothesis-generating and needs to be confirmed in larger trials with longer follow-up. - Highlights: • This study reported the 24-month clinical outcomes of new-generation BP-SES compared with PP-EES in ACS subgroup from CENTURY II study. • This is a pre-specified subgroup analysis of a large randomized, prospective, multicenter clinical trial. • The BP-SES showed good and comparable clinical performance as PP-EES at 24 months. • This substudy has a relatively small sample size and

    Background: To investigate clinical outcomes of percutaneous coronary intervention using a sirolimus-eluting stent with bioresorbable polymer, Ultimaster (BP-SES) compared with a permanent polymer everolimus-eluting stent, Xience (PP-EES) in patients with high risk (ST-segment elevation and non-ST-segment elevation myocardial infarction) acute coronary syndromes (ACS) enrolled in the CENTURY II trial. Methods: CENTURY II is a prospective, multicenter, randomized, single blind, controlled trial comparing BP-SES and PP-EES, with primary endpoint of target lesion failure (TLF) at 9 month post-stent implantation. Out of 1123 patients enrolled in CENTURY II trial, 264 high risk ACS patients were included in this subgroup analysis, and the clinical outcomes including target lesion failure (TLF), target vessel failure (TVF), cardiac death, myocardial infarction, and stent thrombosis were evaluated at 24 months. Results: The baseline clinical, angiographic and procedural characteristics were similar between two groups. At 24 months, TLF occurred in 6.3% of patients receiving a BP-SES and 6.5% of patients receiving a PP-EES (P = 0.95); TVF was 6.3% in patients receiving a BP-SES and 9.4% in patients receiving a PP-EES (P = 0.36). There were no significant differences in cardiac death, myocardial infarction and stent thrombosis rate. Conclusions: BP-SES achieved similar safety and efficacy outcomes as PP-EES in this ACS subgroup of CENTURY II study, at 24-month follow-up. This finding is hypothesis-generating and needs to be confirmed in larger trials with longer follow-up. - Highlights: • This study reported the 24-month clinical outcomes of new-generation BP-SES compared with PP-EES in ACS subgroup from CENTURY II study. • This is a pre-specified subgroup analysis of a large randomized, prospective, multicenter clinical trial. • The BP-SES showed good and comparable clinical performance as PP-EES at 24 months. • This substudy has a relatively small sample size and

    Abstract Antiplatelet therapy is the cornerstone of the pharmacologic management of patients with acute coronary syndrome (ACS). Over the last years, several studies have evaluated old and new oral or intravenous antiplatelet agents in ACS patients. In particular, research was focused on assessing superiority of two novel platelet ADP P2Y12 receptor antagonists (i.e., prasugrel and ticagrelor) over clopidogrel. Several large randomized controlled trials have been undertaken in this setting and a wide variety of prespecified and post-hoc analyses are available that evaluated the potential benefits of novel antiplatelet therapies in different subsets of patients with ACS. The aim of this document is to review recent data on the use of current antiplatelet agents for in-hospital treatment of ACS patients. In addition, in order to overcome increasing clinical challenges and implement effective therapeutic interventions, this document identifies all potential specific care pathway for ACS patients and accordingly proposes individualized therapeutic options.

    'Smoker's paradox' is a controversial phenomenon of an unexpected favourable outcome of smokers post acute myocardial infarction. There are conflicting evidences from the literature so far. We investigate for the existence of this phenomenon in our post acute myocardial infarction patients. We analysed 12,442 active smokers and 10,666 never-smokers diagnosed with STEMI and NSTEMI from the Malaysian National Cardiovascular Database-Acute Coronary Syndrome (NCVD-ACS) year 2006-2013 from 18 hospitals across Malaysia. Comparisons in the baseline characteristics, clinical presentation, in-hospital treatment and short term clinical outcome were made between the two groups. To compare the clinical outcome, an extensive multivariate adjustment was made to estimate the allcause mortality risk ratios for both groups. The active smokers were younger (smokers 53.7 years vs non-smokers 62.3 years P smokers and intravenous thrombolysis was the main reperfusion therapy in both groups. Smokers had a higher rate of in-hsopital coronary revascularisation in NSTEMI group (21.6 % smokers vs 16.7 % non-smokers P non-smokers in the STEMI group. Multivariate adjusted mortality risk ratios showed significantly lower mortality risks of smokers at both in-hospital (RR 0.510 [95 % CI 0.442-0.613]) and 30-day post discharge (RR 0.534 [95 % CI 0.437-0.621]). Smoking seems to be associated with a favourable outcome post myocardial infarction. The phenomenon of 'smoker's paradox' is in fact a reality in our patients population. The definitive explanation for this unexpected protective effect of smoking remains unclear.

    Full Text Available Backgroud: Acute coronary syndrome (ACS is an unstable and dynamic process that includes unstable angina, ST elevation myocardial infarction, and non-ST elevation myocardial infarction. Despite recent technological advances in early diognosis of ACS, differentiating between different types of coronary diseases in the early hours of admission is controversial. The present study was aimed to accurately differentiate between various coronary events, using machine learning techniques. Such methods, as a subset of artificial intelligence, include algorithms that allow computers to learn and play a major role in treatment decisions. Methods: 1902 patients diagnosed with ACS and admitted to hospital were selected according to Euro Heart Survey on ACS. Patients were classified based on decision tree J48. Bagging aggregation algorithms was implemented to increase the efficiency of algorithm. Results: The performance of classifiers was estimated and compared based on their accuracy computed from confusion matrix. The accuracy rates of decision tree and bagging algorithm were calculated to be 91.74% and 92.53%, respectively. Conclusion: The proposed methods used in this study proved to have the ability to identify various ACS. In addition, using matrix of confusion, an acceptable number of subjects with acute coronary syndrome were identified in each class.

    Full Text Available Background: Elevated mean platelet volume (MPV has been proposed as a risk factor for coronary artery disease (CAD and is associated with poor clinical outcome in acute coronary syndrome (ACS. However, some studies have contradictory findings. Hence, we aimed to evaluate the association of MPV with the presence of coronary collateral vessel (CCV in patients with ACS. Objective: To find MPV value in ACS patients and to find the predictive value of MPV in the spectrum of CAD and to examine whether levels of MPV predict the presence of CCVs. Methods: A total of 180 patients with first ACS were included in the study. MPV was measured. All patients underwent coronary angiography to know disease severity and CCVs. The CCVs are graded according to the Rentrop scoring system and according to coronary angiography results; patients were divided into two groups as Group 1 (poor CCV and Group 2 (good CCV. Results: The MPV was 10.74 ± 2 fl in poor collateral group patients and 11.01 ± 1.7 fl in good collateral group (P = 0.421. The presence of CCV was not significantly associated with high levels of MPV. MPV value did not show any prediction of the spectrum of CAD. Conclusion: MPV on admission was not associated with the development of CCV positively in patients with ACS. Furthermore, it is not associated with a number of vessel involvements.

    Congenital heart disease, primarily involving the left-sided structures, is often seen in patients with Turner Syndrome. Moreover, a few case reports have indicated that coronary anomalies may be more prevalent in Turner Syndrome than in the normal population. We therefore set out to systematically investigate coronary arterial anatomy by computed tomographic coronary angiography (coronary CTA) in Turner Syndrome patients. Fifty consecutive women with Turner Syndrome (mean age 47 years [17-71]) underwent coronary CTA. Patients were compared with 25 gender-matched controls. Coronary anomaly was more frequent in patients with Turner Syndrome than in healthy controls [20% vs. 4% (p = 0.043)]. Nine out of ten abnormal cases had an anomalous left coronary artery anatomy (absent left main trunk, n = 7; circumflex artery originating from the right aortic sinus, n = 2). One case had a tubular origin of the right coronary artery above the aortic sinus. There was no correlation between the presence of coronary arterial anomalies and karyotype, bicuspid aortic valve, or other congenital heart defects. Coronary anomalies are highly prevalent in Turner Syndrome. The left coronary artery is predominantly affected, with an absent left main coronary artery being the most common anomaly. No hemodynamically relevant coronary anomalies were found. Copyright © 2016 Society of Cardiovascular Computed Tomography. All rights reserved.

    Full Text Available Aim To compare plasma IL-10 concentrations in patients with Acute Coronary Syndrome (ACS with those in Coronary Artery Disease (CAD.Methods ACS patients hospitalized in intensive coronary care unit (ICCU of Cipto Mangunkusumo Hospital/Faculty of Medicine University of Indonesia (CMH/FMUI, Persahabatan Hospital, MMC Hospital, and Medistra Hospital, Jakarta, between May 2005 and May 2006, were included in this study. The ambulatory CAD patients were taken as comparator. The serum IL-10 level was measured by immunoassay method, and compared by using Independent Student’s t-test. To investigate whether IL-10 serum level could predict ACS, the sensitivity and specificity of this parameter towards ACS in various IL-10 serum levels were calculated as well.Results In this observational study, as many as 146 subjects were analyzed, consisting of 84 ACS patients, and 62 coronary artery disease (CAD. The IL-10 level was higher in the group of ACS patients (7.37 pg/mL + 7.81, CI 95% 5.68-9.07 than that in CAD patients (1.59 pg/mL + 1.55, CI 95% 1.2-1.98. The optimal cut-off point for serum IL-10level is >1.95 pg/mL, with 79.76 % sensitivity and 77.42 % specificity.Conclusion The IL-10 level was higher in the ACS patients compared to that in CAD patients. Serum IL-10 measurement is a quite superior method to distinguish acute and stable condition, eventhough it is not as good as hsCRP for the same purpose.

    Background: Advances in computer tomography (CT) imaging technology in recent years have facilitated the possibility of noninvasive coronary angiography. Purpose: To compare the diagnostic accuracy of 64-channel multidetector computed tomography (MDCT) with conventional invasive coronary angiography (ICA) for the detection of significant coronary stenosis in patients with acute coronary syndrome (ACS). Material and Methods: MDCT was performed in 60 patients classified with non-ST-elevation infarction (NSTEMI) or unstable angina and scheduled for ICA within 3 days. The diagnostic accuracy of MDCT was evaluated using quantitative coronary angiography (QCA) as the gold standard. Results: 48 out of 60 patients had interpretable scans by both MDCT and ICA. On a segment-based analysis, 488 out of 665 segments with a diameter of =1.5 mm, as defined by QCA, were interpretable by MDCT. Sensitivity was 78%, specificity 87%, positive predictive value 47%, and negative predictive value 97% in detecting and excluding significant coronary stenosis, as defined with MDCT. On a per patient-based analysis, sensitivity was 89%, specificity 50%, positive predictive value 84%, and negative predictive value 60%. Conclusion: Limited diagnostic accuracy restricts the usefulness of coronary MDCT in patient groups with a high pretest probability of disease, such as in acute coronary syndrome.

    To evaluate the efficiency and safety of emergency department (ED) coronary computed tomography angiography (CTA) during a 3-year clinical experience. Single-center registry of coronary CTA in consecutive ED patients with suspicion of acute coronary syndrome (ACS). The primary outcome was efficiency of coronary CTA defined as the length of hospitalization. Secondary endpoints of safety were defined as the rate of downstream testing, normalcy rates of invasive coronary angiography (ICA), absence of missed ACS, and major adverse cardiac events (MACE) during follow-up, and index radiation exposure. One thousand twenty two consecutive patients were referred for clinical coronary CTA with suspicion of ACS. Overall, median time to discharge home was 10.5 (5.7-24.1) hours. Patient disposition was 42.7 % direct discharge from the ED, 43.2 % discharge from emergency unit, and 14.1 % hospital admission. ACS rate during index hospitalization was 9.1 %. One hundred ninety two patients underwent additional diagnostic imaging and 77 underwent ICA. The positive predictive value of CTA compared to ICA was 78.9 % (95 %-CI 68.1-87.5 %). Median CT radiation exposure was 4.0 (2.5-5.8) mSv. No ACS was missed; MACE at follow-up after negative CTA was 0.2 %. Coronary CTA in an experienced tertiary care setting allows for efficient and safe management of patients with suspicion for ACS. (orig.)

    The objective of this review was to summarize evidence gathered for the prognostic value of routine and novel blood lipids and lipoproteins measured in patients with acute coronary syndromes (ACS). Data supports clear association with risk and actionable value for non-high-density lipoprotein (Non-HDL) cholesterol and plasma ceramides in a setting of ACS. The prognostic value and clinical actionability of apolipoprotein B (apoB) and lipoprotein(a) [Lp(a)] in ACS have not been thoroughly tested, while the data for omega-3 fatty acids and oxidized low-density lipoprotein (Ox-LDL) are either untested or more varied. Measuring basic lipids, which should include Non-HDL cholesterol, at the time of presentation for ACS is guideline mandated. Plasma ceramides also provide useful information to guide both treatment decisions and follow-up. Additional studies targeting ACS patients are necessary for apoB, Lp(a), omega-3 fatty acids, and Ox-LDL.

    Full Text Available Fractional flow reserve (FFR assessment provides anatomical and physiological information that is often used to tailor treatment strategies in coronary artery disease. Whilst robust data validates FFR use in stable ischaemic heart disease, its use in acute coronary syndromes (ACS is less well investigated. We critically review the current data surrounding FFR use across the spectrum of ACS including culprit and non-culprit artery analysis. With adenosine being conventionally used to induce maximal hyperaemia during FFR assessment, co-existent clinical conditions may preclude its use during acute myocardial infarction. Therefore, we include a current review of instantaneous wave free ratio as a novel vasodilator independent method of assessing lesion severity as an alternative strategy to guide revascularisation in ACS.

    Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

Proteomic data of 252 individuals enrolled in four prospective studies from Australia, Europe and North America were analyzed. 126 of these had suffered from ACS within a period of up to 5 years post urine sampling (cases. Proteomic analysis of 84 cases and 84 matched controls resulted in the discovery of 75 ACS-related urinary peptides. Combining these to a peptide pattern, we established a prognostic biomarker named Acute Coronary Syndrome Predictor 75 (ACSP75. ACSP75 demonstrated reasonable prognostic discrimination (c-statistic = 0.664, which was similar to Framingham risk scoring (c-statistics = 0.644 in a validation cohort of 42 cases and 42 controls. However, generating by a composite algorithm named Acute Coronary Syndrome Composite Predictor (ACSCP, combining the biomarker pattern ACSP75 with the previously established urinary proteomic biomarker CAD238 characterizing coronary artery disease as the underlying aetiology, and age as a risk factor, further improved discrimination (c-statistic = 0.751 resulting in an added prognostic value over Framingham risk scoring expressed by an integrated discrimination improvement of 0.273 ± 0.048 (P < 0.0001 and net reclassification improvement of 0.405 ± 0.113 (P = 0.0007. In conclusion, we demonstrate that urinary peptide biomarkers have the potential to predict future ACS events in asymptomatic patients. Further large scale studies are warranted to determine the role of urinary biomarkers in clinical practice.

    Williams syndrome is a contiguous gene deletion syndrome resulting from a heterozygous deletion on chromosome 7q11.23, and is characterized by distinctive facial features and supravalvular aortic stenosis (SVAS). This syndrome rarely presents unpredictable cardiac death, and yet, as illustrated in the present case, it is still not possible to predict it, even on close monitoring. We herein describe the case of a 6-year-old Japanese girl with Williams syndrome, who had sudden cardiac collapse due to cardiac infarction after pharyngitis. Cardiac failure followed a critical course that did not respond to catecholamine support or heart rest with extracardiac mechanical support. Although marked coronary stenosis was not present, the left coronary cusp abnormally adhered to the aortic wall, which may synergistically cause coronary ostium occlusion with SVAS. Altered hemodynamic state, even that caused by the common cold, may lead to critical myocardial events in Williams syndrome with SVAS. © 2015 Japan Pediatric Society.

    Full Text Available The incidence of bradyarrhythmias in patients with acute coronary syndrome (ACS is 0.3% to 18%. It is caused by sinus node dysfunction (SND, high-degree atrioventricular (AV block, or bundle branch blocks. SND presents as sinus bradycardia or sinus arrest. First-degree AV block occurs in 4% to 13% of patients with ACS and is caused by rhythm disturbances in the atrium, AV node, bundle of His, or the Tawara system. First- or second-degree AV block is seen very frequently within 24 h of the beginning of ACS; these arrhythmias are frequently transient and usually disappear after 72 h. Third-degree AV blocks are also frequently transient in patients with infero-posterior myocardial infarction (MI and permanent in anterior MI patients. Left anterior fascicular block occurs in 5% of ACS; left posterior fascicular block is observed less frequently (incidence < 0.5%. Complete bundle branch block is present in 10% to 15% of ACS patients; right bundle branch block is more common (2/3 than left bundle branch block (1/3. In patients with bradyarrhythmia, intravenous (IV atropine (1-3 mg is helpful in 70% to 80% of ACS patients and will lead to an increased heart rate. The need for pacemaker stimulation (PS is different in patients with inferior MI (IMI and anterior MI (AMI. Whereas bradyarrhythmias are frequently transient in patients with IMI and therefore do not need permanent PS, there is usually a need for permanent PS in patients with AMI. In these patients bradyarrhythmias are mainly caused by septal necrosis. In patients with ACS and ventricular arrhythmias (VTA amiodarone is the drug of choice; this drug is highly effective even in patients with defibrillation-resistant out-of-hospital cardiac arrest. There is general agreement that defibrillation and advanced life support is essential and is the treatment of choice for patients with ventricular flutter/fibrillation. If defibrillation is not available in patients with cardiac arrest due to VTA

    In recent years, acute coronary syndrome(ACS) has been getting more and more attentions. Radionuclide myocardial perfusion imaging (MPI) can make a quick accurate diagnosis for patients with acute chest pain who cann't be diagnosed by conventional methods. The sensitivity and negative predictive value of MPI are relatively high. Besides, MPI can be applicated in the detection of ischemic and infarct size and degree, the risk stratification and the assessment of prognosis of the patients with ACS, and the appraisal of the effect of strategies.

  17. Impact of coronary dominance on in-hospital outcomes after percutaneous coronary intervention in patients with acute coronary syndrome.

    Directory of Open Access Journals (Sweden)

    Toshiki Kuno

    Full Text Available OBJECTIVE: This study evaluated the manner in which coronary dominance affects in-hospital outcomes of acute coronary syndrome (ACS patients undergoing percutaneous coronary intervention (PCI. BACKGROUND: Previous studies have shown that left dominant coronary anatomies are associated with worse prognoses in patients with coronary artery disease. METHODS: Data were analyzed from 4873 ACS patients undergoing PCI between September 2008 and April 2013 at 14 hospitals participating in the Japanese Cardiovascular Database Registry. The patients were grouped based on diagnostic coronary angiograms performed prior to PCI; those with right- or co-dominant anatomy (RD group and those with left-dominant anatomy (LD group. RESULTS: The average patient age was 67.6±11.8 years and both patient groups had similar ages, coronary risk factors, comorbidities, and prior histories. The numbers of patients presenting with symptoms of heart failure, cardiogenic shock, or cardiopulmonary arrest were significantly higher in the LD group than in the RD group (heart failure: 650 RD patients [14.7%] vs. 87 LD patients [18.8%], P = 0.025; cardiogenic shock: 322 RD patients [7.3%] vs. 48 LD patients [10.3%], P = 0.021; and cardiopulmonary arrest: 197 RD patients [4.5%] vs. 36 LD patients [7.8%], P = 0.003. In-hospital mortality was significantly higher among LD patients than among RD patients (182 RD patients [4.1%] vs. 36 LD patients [7.8%], P = 0.001. Multivariate logistic regression analysis revealed that LD anatomy was an independent predictor for in-hospital mortality (odds ratio, 1.75; 95% confidence interval, 1.06-2.89; P = 0.030. CONCLUSION: Among ACS patients who underwent PCI, LD patients had significantly worse in-hospital outcomes compared with RD patients, and LD anatomy was an independent predictor of in-hospital mortality.

    Multislice computed tomography (MSCT) was used to evaluate coronary artery remodeling in patients with acute coronary syndrome (ACS) and stable angina (SA). MSCT was performed in 31 patients with ACS and 26 patients with SA and intravascular ultrasound (IVUS) was performed in 28 of these 57 patients. In both the MSCT and IVUS analyses, coronary artery remodeling was assessed by the remodeling index (RI): RI>1.10 was defined as positive coronary artery remodeling (PCAR) and RI<0.95 was defined as negative coronary artery remodeling (NCAR). The RI assessed by MSCT closely correlated with that of IVUS (r=0.86, n=28). The vessel area at the region of maximum luminal narrowing was also comparable between the MSCT and IVUS measurements (r=0.92). PCAR was present in 19 patients (61.3%) with ACS, but in none of the patients with SA (p<0.0001). However, NCAR was present in only 1 patient with ACS (3.2%), but was present in 18 patients (62.9%) with SA. The RI was significantly larger in patients with ACS (1.19±0.18) than in those with SA (0.89±0.10, p<0.0001). MSCT accurately assesses coronary artery remodeling. (author)

    Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp's Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    Coronary artery aneurysm (CAA) is an uncommon clinical finding, with an incidence varying from 1.5%-4.9% in adults, and is usually considered a variant of coronary artery disease (CAD). CAA identified in the context of acute coronary syndrome (ACS) represents a unique management challenge, particularly if the morphology of the CAA is suspected to have provoked the acute clinical syndrome. CAA is associated with thrombus formation due to abnormal laminar flow, as well as abnormal platelet and endothelial-derived pathophysiologic factors within the CAA. Once formed, mural thrombus may potentiate the deposition of additional thrombus within aneurysmal segments. Percutaneous revascularization of CAA has been associated with complications including distal embolization of thrombus, no-reflow phenomenon, stent malapposition, dissection, and rupture. Presently, there are no formal guidelines to direct the management of CAA in patients presenting with ACS; controversies exist whether conservative, surgical, or catheter-based management should be pursued. In this manuscript, we present an extensive review of the existing literature and associated clinical guidelines, and propose a management algorithm for patients with this complex clinical scenario. Armed with this perspective, therapeutic decisions may be tailored to synthesize patient factors and preferences, individualized clinical assessment, and existing American Heart Association/American College of Cardiology guidelines for management of ACS.

    Acute coronary syndromes (ACS) may precipitate up to a third of acute heart failure (AHF) cases. We assessed the characteristics, initial management, and survival of AHF patients with (ACS-AHF) and without (nACS-AHF) concomitant ACS. Data from 620 AHF patients were analyzed in a prospective multicenter study. The ACS-AHF patients (32%) more often presented with de novo AHF (61% vs. 43%; P coronary procedures (angiography, percutaneous coronary intervention, coronary artery bypass graft surgery), were more frequent in ACS-AHF (P < .001 for all). Although 30-day mortality was significantly higher for ACS-AHF (13% vs. 8%; P = .03), survival in the 2 groups at 5 years was similar. Overall, ACS was an independent predictor of 30-day mortality (adjusted odds ratio 2.0, 95% confidence interval 1.07-3.79; P = .03). Whereas medical history and the manifestation and initial treatment of AHF between ACS-AHF and nACS-AHF patients differ, long-term survival is similar. ACS is, however, independently associated with increased short-term mortality. Copyright © 2014 Elsevier Inc. All rights reserved.

    Acute coronary syndrome (ACS) is an important cause of mortality and morbidity in the general population. Recent advances in percutaneous coronary intervention (PCI) and optimal medical treatment have helped to improve the prognosis of patients with ACS. The previous reports indicated that women with ACS have a higher risk of adverse outcomes. However, sex differences in clinical outcomes with contemporary coronary revascularization and medical therapy for ACS have not been elucidated. We analyzed data from 676 consecutive patients with ACS (female, n = 166; male, n = 510) who were treated by emergency PCI between 2011 and 2014 at Juntendo Shizuoka Hospital. The patients were grouped according to sex. We defined major adverse cardiovascular events as a composite of all-cause death and ACS recurrence at 1 year and compared rates of major adverse cardiac events (MACE) between the groups. Women were older (75.4 ± 11.0 vs. 66.2 ± 12.2 years) and had a higher rate of multi-vessel disease, chronic kidney disease, and Killip IV at presentation. The cumulative rate of MACE at 1 year was significantly higher among women than men (17.5 vs. 10.2 %, p = 0.02, log-rank test). However, the association between women and a higher risk of MACE was attenuated after adjusting for age (HR 1.25, 95 % CI 0.77-2.00, p = 0.36) and other variables (HR 0.93, 95 % CI 0.36-2.44, p = 0.88). Adjustment for age and other risk factors attenuated sex differences in mid-term clinical outcomes among patients with ACS after emergency PCI.

    Previous studies have examined risk factors for the development of heart failure (HF) subsequent to acute coronary syndrome (ACS). Our study seeks to clarify the clinical variables that best characterize patients who remain free from HF after coronary artery bypass grafting (CABG) surgery for ACS to determine novel biological factors favouring freedom from HF in prospective translational studies. Nova Scotia residents (1995-2012) undergoing CABG within 3 weeks of ACS were included. The primary outcome was freedom from readmission to hospital due to HF. Descriptive statistics were generated, and a Cox proportional hazards model assessed outcome with adjustment for clinical characteristics. Of 11 936 Nova Scotians who underwent isolated CABG, 3264 (27%) had a recent ACS and were included. Deaths occurred in 210 (6%) of subjects prior to discharge. A total of 3054 patients were included in the long-term analysis. During follow-up, HF necessitating readmission occurred in 688 (21%) subjects with a hazard ratio of 12% at 2 years. The adjusted Cox model demonstrated significantly better freedom from HF for younger, male subjects without metabolic syndrome and no history of chronic obstructive pulmonary disease, renal insufficiency, atrial fibrillation, or HF. Our findings have outlined important clinical variables that predict freedom from HF. Furthermore, we have shown that 12% of patients undergoing CABG after ACS develop HF (2 years). Our findings support our next phase in which we plan to prospectively collect blood and tissue specimens from ACS patients undergoing CABG in order to determine novel biological mechanism(s) that favour resolution of post-ACS inflammation. © 2017 The Authors.

    Full Text Available A number of "interesting" risk markers have been proposed as providing prognostic information in acute coronary syndromes (ACS. Elevation in plasma inflammatory and necrosis biomarkers have been related to future cardiovascular events in individuals with or without prior myocardial infarction. Recently BNP and pro-BNP are entered in clinical practice to recognize patients at major risk, providing incremental information respect to the traditional markers. Together with these laboratory indexes, a few of promising laboratory markers once easily available, could become useful in identification of patients at high risk. Several studies evaluated many markers of platelet aggregation, endothelial dysfunction and vascular thrombosis, but it is not yet clear whether each of the proposed markers may provide incremental predictive information. We describe, following the most studies reported in literature, the laboratory markers with potential clinical and prognostic power that could early help physicians in the identifi cation of patients with impaired coronary disease and more narrowed coronary arteries.

    Full Text Available Arterial chronic hypertension (HTN is a well-known cardiovascular risk factor for development of atherosclerosis. In order to explain the relation between HTN and acute coronary syndromes the following factors should be considered: (1 risk factors are shared by the diseases, such as genetic risk, insulin resistance, sympathetic hyperactivity, and vasoactive substances (i.e., angiotensin II; (2 hypertension is associated with the development of atherosclerosis (which in turn contributes to progression of myocardial infarction. From all the registries and the data available up to now, hypertensive patients with ACS are more likely to be older, female, of nonwhite ethnicity, and having a higher prevalence of comorbidities. Data on the prognostic role of a preexisting hypertensive state in ACS patients are so far contrasting. The aim of the present paper is to focus on hypertensive patients with ACS, in order to better elucidate whether these patients are at higher risk and deserve a tailored approach for management and followup.

    To determine levels of C-reactive protein (CRP) and its association with coronary markers, lipid profile and markers of coagulation in patients of acute coronary syndrome (ACS). The study was conducted at Shifa college of Medicine and Shifa international hospital for a period of one year (November 2005-December 2006). Patients and Methods: Sixty nine age matched controls and 133 consecutive patients of ACS were included in the study. CRP were measured by immunoturbidometric method, MB fraction of creatine kinase (CK-MB) and Troponin-1 by micro-particle enzyme immunoassay, lipid levels by Colorimetric Enzymatic methods, platelets by celldyn and coagulation markers were measured by CA-50 Sysmax. At admission mean CRP levels, cardiac biomarkers, lipid profile and coagulation markers were significantly increased in patients of ACS versus controls. Within the patients of ACS the mean levels of CRP, CK-MB, Trop I, prothrombin time (PT) and activated partial thromboplastin time (Am) were significantly raised in patients with ST - elevation myocardial infarction (STEMI) and non STEMI (NSTEMI) versus patients of unstable angina (VA). Association between CRP levels and coronary markers, coagulation markers and lipid profile was found to be non significant. The CRP levels were increased in patients with ACS as compared to controls. The CRP levels were insignificantly correlated with coronary markers (CK-MB, Trop I), coagulation markers (platelet count, PT, Am), and lipid profile (cholesterol, triglyceride, HDL and LDL cholesterol) in patients with ACS.

    Coronary artery disease (CAD) is the major cause of death nearly all over the world, and accurate and rapid diagnosis of CAD is of major medical and economic importance. The aim of this study was to evaluate the serum and saliva levels of cathepsin L in patients with acute coronary syndrome (ACS). In a cross-sectional study, 39 patients with ACS and 28 with controls were recruited to the study, and cathepsin L levels were measured in serum, resting saliva, and stimulated saliva obtained 12 and 24 h after the onset of ACS by ELISA method. Statistical analyses of Fisher's exact test, the Student's t-test or Kruskal-Wallis test were performed. Stimulated saliva cathepsin L levels in patients with ACS 12 hours but not 24 hours after admission showed significant decrease compared with that in control subjects. However, there were no significant differences in serum and unstimulated saliva cathepsin L levels between groups. Serum and saliva levels of cathepsin L remain unchanged in patients with ACS and hence may not be a promising factor in CAD risk assessment. It seems that serum and saliva cathepsin L may not be a good biomarker for CHD.

    Von Willebrand disease (vWD) results from quantitative or qualitative deficiency of von Willebrand factor (vWF). The occurrence of myocardial infarction is very rare in patients with vWD. A few case reports of acute coronary syndrome (ACS) in vWD patients are present in the literature, but no definite management recommendations are available for such patients. We report a case of successful percutaneous coronary intervention (PCI) with bare-metal stent (BMS) implantation in a 46-year-old woman with type 1 vWD and history of coronary artery disease (CAD). She received periprocedural dual-antiplatelet therapy for 2 weeks and then continued aspirin without any bleeding complications. The optimal management of patients with vWD and ACS is complex and presents a therapeutic challenge. We propose that dual-antiplatelet therapy can be used safely in most vWD patients presenting with ACS as most of them are type 1 vWD. PCI with BMS can be done safely. Long-term management of these patients requires a systemic approach including hematological consultation, ascertaining vWF levels, as well as patient education and close outpatient follow-up.

    To investigate the relationship between inflammatory factors and two Chinese medicine (CM) syndrome types of qi stagnation and blood stasis (QSBS) and qi deficiency and blood stasis (QDBS) in patients with acute coronary syndrome (ACS). Sixty subjects with ACS, whose pathogenesis changes belongs to qi disturbance blood stasis syndrome, were divided into 2 groups: 30 in the QSBS group and 30 in the QDBS group. The comparative analysis on them was carried out through comparing general information, coronary angiography and inflammatory factors including intracellular adhesion molecule-1 (ICAM-1), chitinase-3-like protein 1 (YKL-40) and lipoprotein-associated phospholipase A2 (Lp-PLA2). Compared with the QSBS group, Lp-PLA2 and YKL-40 levels in the QDBS group showed no-significant difference (P>0.05); ICAM-1 was significantly higher in the QDBS group than in the QSBS group in the pathological processes of qi disturbance and blood stasis syndrome of ACS (Psyndrome typing of QSBS and QDBS, which provides a research direction for standardization research of CM syndrome types.

    The risk of recurrence of myocardial infarction (MI) in HIV patients presenting with acute coronary syndrome (ACS) is well known, but there is limited evidence about potential differences in coronary plaques compared to non-HIV patients. In this multicenter case-control study, HIV patients presenting with ACS, with intravascular-ultrasound (IVUS) data, enrolled between February 2015 and June 2017, and undergoing highly active antiretroviral therapy (HAART), were retrospectively compared to non-HIV patients presenting with ACS, before and after propensity score with matching, randomly selected from included centers. Primary end-point was the prevalence of multivessel disease. Secondary end-points were the prevalence of abnormal features at IVUS, the incidence of major-acute-cardiovascular-events (MACE), a composite end point of cardiovascular death, MI, target lesion revascularization (TLR), stent thrombosis (ST), non-cardiac death and target vessel revascularization (TVR). For each end-point, a subgroup analysis was conducted in HIV patients with CD4 cell count <200/mm 3 . Before propensity score, 66 HIV patients and 120 non-HIV patients were selected, resulting in 20 and 40 after propensity score. Patients with multivessel disease were 11 and 17, respectively (p = 0.56). IVUS showed a lower plaque burden (71% vs. 75%, p < 0.001) and a higher prevalence of hyperechoic non-calcified plaques (100% vs. 35%, p < 0.05) in HIV patients; a higher prevalence of hypoechoic plaques (7% vs. 0%, p < 0.05), a higher incidence of MACE (17.4% vs. 9.1% vs. l'8.0%, p < 0.05), MI recurrence (17.2% vs. 0.0% vs. 2.3%, p < 0.05), and ST (6.7% vs. 0.3% vs. 03%, p < 0.05) in HIV patients with CD4 < 200/mm 3 . Our study may provide a part of the pathophysiological basis of the differences in coronary arteries between HIV-positive and HIV-negative patients, suggesting that the former present with peculiar morphological features at IVUS, even after adjustment for clinical variables

Objective: Compare ACS-related length of stay (LOS, total admission cost, and total admission cost by day of discharge/death for patients who died during an inpatient admission with a matched cohort discharged alive following an ACS-related inpatient stay. Methods: Medical and pharmacy claims (2009–2012 were used to identify admissions with a primary diagnosis of ACS from patients with at least 6 months of continuous enrollment prior to an ACS admission. Patients who died during their ACS admission (deceased cohort were matched (one-to-one to those who survived (survived cohort on age, sex, year of admission, Chronic Condition Index score, and prior revascularization. Mean LOS, total admission cost, and total admission cost by the day of discharge/death for the deceased cohort were compared with the survived cohort. A generalized linear model with log transformation was used to estimate the differences in the total expected incremental cost of an ACS admission and by the day of discharge/death between cohorts. A negative binomial model was used to estimate differences in the LOS between the two cohorts. Costs were inflated to 2013 dollars. Results: A total of 1,320 ACS claims from patients who died (n=1,320 were identified and matched to 1,319 claims from the survived patients (n=1,319. The majority were men (68% and mean age was 56.7±6.4 years. The LOS per claim for the deceased cohort was

    Drug-eluting stents (DES), delivering antiproliferative drugs from a durable polymer, have shown to reduce in-stent restenosis after percutaneous coronary intervention (PCI) compared to bare-metal stents (BMS). However, they have been associated with a hypersensitivity reaction, delayed healing, and incomplete endothelialization, which may contribute to an increased risk of late stent thrombosis. Consequently, a prolonged duration of dual antiplatelet therapy (DAPT) is needed, with an increased risk of bleeding complication. A number of stent technologies are being developed in an attempt to modify late thrombotic events and DAPT duration. The Optimax™ stent is such a novel, next generation bioactive stent (BAS), in which a thicker layer of titanium-nitride-oxide coating is inserted over the stent struts. The rationale of this is to obtain more efficient and rapid vascular healing at the site of the stent implantation. The aim of TIDES-ACS Trial is to compare clinical outcome in patients presenting with ACS, treated with PCI using Optimax-BAS versus Synergy™-EES. Second objective is to explore whether the Optimax™-BAS use is superior compared with Synergy™-EES use with respect of hard end points (cardiac death, myocardial infarction [MI] and major bleeding). A prospective, randomized, multicenter trial (ClinicalTrials.gov Identifier: NCT02049229), will be conducted in interventional centres in Finland (six centres), France (five centres) and Holland (two centres), including a total of 1800 patients.

    Full Text Available Background: Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS. Objective: To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods: Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged <65 years, hospitalized with diagnosis of ACS. The Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI, which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE, emotional distancing (EmD, dehumanization (De and professional fulfillment (PF. The Lipp’s Stress Symptoms Inventory for Adults (LSSI was applied to evaluate global stress. Results: Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion: We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis’ most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

    To assess prevalence, characteristics and management of acute coronary syndromes in sub-Saharan Africa population. Prospective survey from January, 2010 to December, 2013, carried out among patients aged 18 years old, admitted to intensive care unit of Abidjan Heart Institute for acute coronary syndrome (ACS). Four hundred and twenty-five (425) patients were enrolled in this study. Prevalence of ACS was 13.5%. Mean age was 55.4±11 years. Clinical presentation was predominantly ST-segment elevation myocardial infarction (STEMI) in 71.5% of subjects, non-ST-segment elevation acute coronary syndrome (NSTE-ACS) accounted for 28.5%. Two hundred and eighty patients (65.9%) were transferred by unsafe transportation. Among the 89 patients admitted within 12hours of the onset of symptoms, primary percutaneous coronary intervention was performed in 20 patients (22.5%), or 6.6% of STEMI as a whole. Twenty-five patients (8.2%) received fibrinolytic therapy with alteplase. In-hospital death rate was 10%. The prevalence of acute coronary syndromes is increasing in sub-Saharan Africa. Excessive delays of admission and limited technical facilities are the major difficulties of their management in our regions. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Clinical practice guidelines recommend admitting patients with stable non-ST-segment elevation acute coronary syndrome (NSTE ACS) to telemetry units, yet up to two-thirds of patients are admitted to higher-acuity critical care units (CCUs). The outcomes of patients with stable NSTE ACS initially admitted to a CCU vs a cardiology ward with telemetry have not been described. We used population-based data of 7,869 patients hospitalized with NSTE ACS admitted to hospitals in Alberta, Canada, between April 1, 2007, and March 31, 2013. We compared outcomes among patients initially admitted to a CCU (n=5,141) with those admitted to cardiology telemetry wards (n=2,728). Patients admitted to cardiology telemetry wards were older (median 69 vs 65years, PST-segment myocardial infarction or unstable angina. There were no differences in clinical outcomes observed between patients with NSTE ACS initially admitted to a ward or a CCU. These findings suggest that stable NSTE ACS may be managed appropriately on telemetry wards and presents an opportunity to reduce hospital costs and critical care capacity strain.

    Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC) is a priority. To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS) as a predictor of cardiovascular complications during hospitalization. Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1), point of minimum circumference (2); immediately above the iliac crest (3), umbilicus (4), one inch above the umbilicus (5), one centimeter above the umbilicus (6), smallest rib and (7) the point of greatest circumference around the waist (8). Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67%) patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

    Congestive heart failure (CHF) is a common and preventable complication of acute coronary syndrome (ACS). Nevertheless, ACS risk scores have not been shown to predict CHF risk. We investigated whether the at-discharge Global Registry of Acute Coronary Events (GRACE) score predicts heart failure admission following ACS. Five-year mortality and hospitalization data were obtained for patients admitted with ACS from June 1999 to September 2009 to a single centre of the GRACE registry. CHF was defined as any admission assigned WHO International Classification of Diseases 10 diagnostic code I50. The hazard ratio (HR) for CHF according to GRACE score was estimated in Cox models adjusting for age, gender and the presence of CHF on index admission. Among 1,956 patients, CHF was recorded on index admission in 141 patients (7%), and 243 (12%) were admitted with CHF over 3.8 median years of follow-up. Compared to the lowest quintile, patients in the highest GRACE score quintile had more CHF admissions (116 vs 17) and a shorter time to first admission (1.2 vs 2.0 years, HR 9.87, 95% CI 5.93-16.43). Per standard deviation increment in GRACE score, the instantaneous risk was more than two-fold higher (HR 2.28; 95% CI 2.02-2.57), including after adjustment for CHF on index admission, age and gender (HR 2.49; 95% CI 2.06-3.02). The C-statistic for CHF admission at 1-year was 0.74 (95% CI 0.70-0.79). The GRACE score predicts CHF admission, and may therefore be used to target ACS patients at high risk of CHF with clinical monitoring and therapies. © The European Society of Cardiology 2014.

    This study was designed to determine whether coronary CT angiography (CTA) can detect features of plaque disruption in clinically stable patients and to compare lesion prevalence and features between stable patients and those with acute coronary syndrome (ACS). We retrospectively identified patients undergoing CTA, followed by invasive coronary angiography (ICA) within 60 days. Quantitative 3-vessel CTA lesion analysis was performed on all plaques ≥25% stenosis to assess total plaque volume, low attenuation plaque (LAP, disruption, including ulceration and intra-plaque dye penetration (IDP). ICA was employed as a reference standard for disruption. A total of 145 (94 ACS and 51 stable) patients were identified. By CTA, plaque disruption was evident in 77.7% of ACS cases. Although more common among those with ACS, CTA also detected plaque disruption in 37.3% of clinically stable patients (P disruption as determined by CTA. Though the prevalence of plaque disruption is less than patients with ACS, these findings support the concept that some clinically stable patients may harbour 'silent' disrupted plaques. These findings may have implications for detection of 'at risk' plaques and patients. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2015.

Current standard antithrombotic therapy after coronary stent implantation consists of lifelong aspirin and clopidogrel for a variable period depending in part on the stent type. Despite its well-established efficacy in reducing cardiac-related death, myocardial infarction, and stroke, dual antiplatelet therapy with aspirin and clopidogrel is not without shortcomings. While clopidogrel may be of little beneficial effect if administered immediately prior to PCI and may even increase major bleeding risk if coronary artery bypass grafting is anticipated, early discontinuation of the drug may result in insufficient antiplatelet coverage with thrombotic complications. Optimal and rapid inhibition of platelet activity to suppress ischemic and thrombotic events while minimizing bleeding complications is an important therapeutic goal in the management of patients undergoing percutaneous coronary intervention. In this article we present an overview of the literature on clinical trials evaluating the different aspects of antithrombotic therapy in patients

    Full Text Available Aim. To compare effect of percutaneous balloon angioplasty (PCA and a systemic thrombolysis (STL on the central and intracardiac hemodynamics in patients with acute coronary syndrome (ACS with ST segment elevation.Material and methods. 80 patients with ACS with ST segment elevation were included in the study. Patients were split into 2 groups depending on reperfusion strategy. PCA was performed in 55 patients (first group. 25 patients of the second group had STL with Streptokinase, i/v, 1 500 000 units per hour. Echocardiography was performed in all patients at admission and after 3 and 7 days of treatment to evaluate intracardiac hemodynamics.Results. Both reperfusion methods significantly increase of ejection fraction (EF and maximal output speed of left ventricle (LV. Increase of LV EF in patients after PCA was higher than this in patients after STL. PCA improved LV diastolic function; STL did not change this characteristic. After PCA working diagnosis of ACS was transformed to the following final diagnosis: acute myocardial infarction (AMI with Q, AMI without Q and unstable angina in 37,5, 30,4 and 32,1% of patients, respectively. After STL diagnosis of AMI with Q was defined in all patients.Conclusion. PCA in patients with ACS with ST segment elevation results in fast improvement of global systolic and diastolic LV function. Besides, PCA prevents AMI with Q in a half of these patients.

    Full Text Available OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment undergoing coronary angioplasty with stent placement. These 74 patients were compared with 31 patients with stable coronary syndromes (stable angina or stable silent ischemia undergoing the same procedure. RESULTS: No death and no need for revascularization of the culprit artery occurred in the in-hospital phase. The incidences of acute non-Q-wave myocardial infarction were 1.4% and 3.2% (p=0.6 in the unstable and stable coronary syndrome groups, respectively. In the late follow-up (11.2±7.5 months, the incidences of these events combined were 5.7% in the unstable coronary syndrome group and 6.9% (p=0.8 in the stable coronary syndrome group. In the multivariate analysis, the only variable with a tendency to significance as an event predictor was diabetes mellitus (p=0.07; OR=5.2; 95% CI=0.9-29.9. CONCLUSION: The in-hospital and late evolutions of patients with unstable coronary syndrome undergoing angioplasty with intracoronary stent implantation are similar to those of the stable coronary syndrome group, suggesting that this procedure is safe and efficacious when performed in unstable coronary syndrome patients.

    Acute Coronary Syndrome (ACS) is used to describe the spectrum of coronary artery disease (CAD). Troponin T is the determinant of the most sensitive marker of ACS, but there aren’t all hospitals have this because of expensiveness. Mean Platelet Volume (MPV) is one of the components of a complete blood routine examination and relatively cheap as a marker in ACS. Determining the sensitivity and specificity of MPV in detecting cases of the acute coronary syndrome, 325 subjects’ medical records were from the period of July 2013 to June 2014; 228 ACS patients met the inclusion criteria. 228 subjects showed a risk factor for age ≥45years of more 195 (85.5%). 122 subjects with hypertension (53.5%) and subjects who smoked 118 (51.8%) that suffered most ACS. Subjects with risk factors for diabetes mellitus, obesity, menopause and dyslipidemia in this study was lower than non-diabetic 161 (70.6%), obese189 (82.9%), nonmenopause 196 (86%) and normal lipid 210 (92.1%). But there was norelation between risk factor with MPV and troponin T statistically. The results of diagnostic tests MPV for the evaluation of patients with ACS, sensitivity 92%, specificity 71%, positive predictive value 95% and negative predictive value 58%.

    Acute coronary syndrome (ACS) remains a major burden on morbidity and mortality in the United States. Medical professionals and students often use the mnemonic 'MONA' (morphine, oxygen, nitroglycerin and aspirin) to recall treatments for ACS; however, this list of therapies is outdated. We provide a historical perspective on 'MONA,' attempt to uncover its origin in the medical literature, and demonstrate the myriad changes that have occurred over the last 50 years of ACS management. We have developed a novel mnemonic, 'THROMBINS2' (thienopyridines, heparin/enoxaparin, renin-angiotensin system blockers, oxygen, morphine, beta blocker, intervention, nitroglycerin, statin/salicylate) to help bedside clinicians recall all the elements of contemporary ACS management. We demonstrate the mortality benefit for each component of contemporary ACS management, correlating the continued improvement with historical data on mortality after myocardial infarction. We encourage providers to utilize this mnemonic to explore options and guide treatments in ACS patients.

    To determine the usefulness of myeloperoxidase in discriminating between patients with acute coronary syndrome and patients with chest pain by other causes. The study included all patients over 18 years of age who come consecutively to the emergency department from September 2015 to December 2015 with chest pain of non-traumatic origin. The initial patient evaluation was performed according to the study protocol for patients with suspected acute coronary syndrome (ACS) in our Emergency Department. This included the serial measurement of troponin, and in this case myeloperoxidase, with serialization on admission and at 6h. For the determination of myeloperoxidase (MPO), a single step sandwich enzyme immunoassay by Siemens, automated on a Dimension analyser, was used. Statistically significant differences were observed in the concentration of myeloperoxidase at time 0 among patients diagnosed with ACS: 505 (413)pmol/L, and non-ACS patients: 388 (195)pmol/L (p<.001), as well as at 6h (p<.001). An area under the curve ROC of 0.824 was obtained at 6h for ACS patients, with a confidence interval of 95% from 0.715 to 0.933 and a level of significance of p<.001. Statistically significant differences were also found in the concentration of myeloperoxidase at time 0 and at 6h among patients with ACS and patients with heart disease other than coronary artery disease. The concentration of MPO helps to differentiate between ACS and non-ACS patients, as well as between ACS patients and patients with heart diseases other than coronary artery disease.

    The advent of potent antiplatelet and antithrombotic agents over the past decade has resulted in significant improvement in reducing ischemic events in acute coronary syndrome (ACS). However, the use of antiplatelet and antithrombotic combination therapy, often in the settings of percutaneous coronary intervention (PCI), has led to an increase in the risk of bleeding. In patients with non-ST elevation myocardial infarction treated with antithrombotic agents, bleeding has been reported to occur in 0.4%–10% of patients, whereas in patients undergoing PCI, periprocedural bleeding occurs in 2.2%–14% of cases. Until recently, bleeding was considered an intrinsic risk of antithrombotic therapy, and efforts to reduce bleeding have received little attention. There have been increasing data demonstrating that bleeding is associated with adverse outcomes, including myocardial infarction, stroke, and death. Therefore, it is imperative to optimize patient outcomes by adopting pharmacological and nonpharmacological strategies to minimize bleeding while maximizing treatment efficacy. In this paper, we present a review of the bleeding classifications used in large-scale clinical trials in patients with ACS and those undergoing PCI treated with antiplatelets and antithrombotic agents, adverse outcomes, particularly mortality associated with bleeding complications, and suggested predictive risk factors. Potential mechanisms of the association between bleeding and mortality and strategies to reduce bleeding complications are also discussed. PMID:21915172

    Full Text Available Background. To differentiate acute coronary syndrome (ACS from other causes in patients presenting with chest pain at the emergency department (ED is crucial and can be performed by the nurse triage. We evaluated the effectiveness of the ED nurse triage for ACS of the tertiary care hospital. Methods. We retrospectively enrolled consecutive patients who were identified as ACS at risk patients by the ED nurse triage. Patients were categorized as ACS and non-ACS group by the final diagnosis. Multivariate logistic analysis was used to predict factors associated with ACS. An online model predictive of ACS for the ED nurse triage was constructed. Results. There were 175 patients who met the study criteria. Of those, 28 patients (16.0% were diagnosed with ACS. Patients with diabetes, patients with previous history of CAD, and those who had at least one character of ACS chest pain were independently associated with having ACS by multivariate logistic regression. The adjusted odds ratios (95% confidence interval were 4.220 (1.445, 12.327, 3.333 (1.040, 10.684, and 12.539 (3.876, 40.567, respectively. Conclusions. The effectiveness of the ED nurse triage for ACS was 16%. The online tool is available for the ED triage nurse to evaluate risk of ACS in individuals.

    Risk evaluation of patients hospitalized with acute coronary syndrome (ACS) may contribute to their short-term prognosis improvement. The aim of this work was to develop a prediction index (score) for the risk assessment of 30-day death of ACS patients, using clinical and biological measurements at hospital admission. A sample of 6 Greek hospitals was selected, and almost all consecutive 2172 ACS patients from October 2003 to September 2004 were enrolled. Sociodemographic, biochemical, clinical, and lifestyle characteristics were recorded. Using as components age, systolic blood pressure, white blood cell count, creatine kinase-MB, and creatinine levels at the time of admission and the time between the onset of symptoms and presentation at hospital, a risk score (Greek Acute Coronary Syndrome score; range, 6-36) was developed and tested against in-hospital and 30-day outcome of the patients. The Greek Acute Coronary Syndrome score showed strong discriminating ability for in-hospital mortality (area under the receiver operating characteristic curve, 0.812; 95% confidence interval, 0.750-0.874; P period.

    Prior aspirin treatment is considered a risk factor for adverse outcomes in acute coronary syndrome (ACS) patients. The relationships between aspirin pretreatment and findings on quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS), as well as clinical outcomes, are not well understood. In the PROSPECT trial, QCA and triple-vessel IVUS imaging were performed after successful percutaneous coronary intervention (PCI) of the culprit lesion(s) in ACS patients. We compared patients receiving aspirin within 7 days of enrollment to those naive to aspirin. Propensity score matching was performed to adjust for differences in baseline characteristics. Aspirin-pretreated patients (n = 236; 35%) were older and more likely to have known coronary disease than those without pretreatment (P≤.01 for all). Pretreated patients had more untreated non-culprit lesions with angiographic and IVUS characteristics predictive of future events (53.1% vs 38.6%; PPROSPECT trial, aspirin pretreatment identifies an older population with more advanced coronary disease. Aspirin pretreatment was not an independent predictor of MACE in ACS patients treated with an early invasive strategy. The extent to which aspirin pretreatment is a risk factor for adverse events after PCI in ACS should be revisited.

    To assess the association of leisure-time exercise and television (TV) viewing, a sedentary marker, with acute coronary syndrome (ACS) in Albania, a transitional country in Southeast Europe. A population-based case-control study was conducted among Tirana residents in 2003-2006. Information on leisure-time exercise (transformed into kilocalories of energy expenditure) and daily hours of TV viewing was obtained by interviewer-administered questionnaire. 460 non-fatal ACS patients (368 men, 92 women) and 628 coronary heart disease-free controls (413 men, 215 women) were studied. Adjusted for socio-demographic characteristics, conventional coronary risk factors and leisure-time exercise, TV viewing was associated with ACS in women (OR=1.66, 95%CI=1.12-2.46 per hour/day viewing), but not in men (OR=0.93, 95%CI=0.81-1.07; P for sex-interaction=0.02). A low level of leisure-time exercise (adjusted also for TV viewing) was associated with ACS similarly in men and women (pooled sexes OR=2.03, 95%CI=1.29-3.22 for bottom vs top tertile of energy expenditure). Leisure-time inactivity is confirmed as an important risk factor for ACS also in Southeastern Europe. TV viewing may be an informative coronary risk marker in transitional societies, especially in women.

    Patients with acute coronary syndromes (ACS) display diffuse coronary atheroma instability and heightened risk of early and late recurrent coronary events. We compared the long-term antiatherosclerotic efficacy of high-intensity statins in patients with ACS when compared with stable disease. Study of Coronary Atheroma by Intravascular Ultrasound: Effect of Rosuvastatin Versus Atorvastatin (SATURN) used serial intravascular ultrasound measures of coronary atheroma volume in patients treated with rosuvastatin 40 mg or atorvastatin 80 mg for 24 months. The overall effect of high-intensity statins on the change in coronary percent atheroma volume and major adverse cardiovascular events (death/nonfatal myocardial infarction/coronary revascularization) were evaluated in this post hoc analysis. When compared with non-ACS patients (n=678), patients with ACS (n=361) were younger, actively smoking, and have had a previous myocardial infarction (all P<0.001). At baseline, patients with ACS exhibited lower high-density lipoprotein cholesterol (43.5±11 versus 45.8±11 mg/dL; P=0.002), a higher apolipoprotein B: apolipoprotein A-1 ratio (0.90±0.24 versus 0.83±0.24; P<0.001) and greater percent atheroma volume (37.3±8.5% versus 35.9±8.1%; P=0.01) when compared with non-ACS patients. Despite similar achieved levels of lipid and inflammatory markers after high-intensity statin therapy, patients with ACS demonstrated greater percent atheroma volume regression than non-ACS patients (-1.46±0.14 versus -0.89±0.13; P=0.003). After propensity-weighted multivariable adjustment, baseline percent atheroma volume (P<0.001) and an ACS clinical presentation (P=0.02) independently associated with plaque regression. The 24-month major adverse cardiovascular events-free survival was similar between patients with ACS and non-ACS (90.6 versus 92.9%; P=0.25). Long-term high-intensity statin therapy caused greater plaque regression and comparable major adverse cardiovascular events rates in

    Patients with chest pain, elevated troponin, and unobstructed coronary disease present a clinical dilemma. The purpose of this study was to investigate the incremental diagnostic value of cardiovascular magnetic resonance (CMR) in a cohort of patients with suspected acute coronary syndrome (ACS) and unobstructed coronary arteries. Data files of patients meeting the inclusion criteria in two cardiology centres were searched and analysed. The inclusion criteria included: 1) thoracic pain suspected with ACS; 2) a significant increase in the high-sensitive Troponin T value; 3) ECG changes; 4) coronary arteries without any significant stenosis; 5) a CMR examination included in the diagnostic process; 6) an uncertain diagnosis before the CMR exam; and 7) the absence of known CMR and contrast media contraindications. Special attention was paid to the benefits of CMR in determining the final diagnosis. In total, 136 patients who underwent coronary angiography for chest pain were analysed. The most frequent underlying causes were myocarditis (38%) and perimyocarditis (18%), followed by angiographically unrecognised acute myocardial infarction (18%) and Takotsubo cardiomyopathy (15%). The final diagnosis remained unclear in 6% of the patients. The contribution of CMR in determining the final diagnosis determination was crucial in 57% of the patients. In another 35% of the patients, CMR confirmed the suspicion and, only 8% of the CMR examinations did not help at all and had no influence on diagnosis or treatment. CMR provided a powerful incremental diagnostic value in the cohort of patients with suspected ACS and unobstructed coronary arteries. CMR is highly recommended to be incorporated as an inalienable part of the diagnostic algorithms in these patients.

    Nonadherence to medication may lead to poor medical outcomes. To describe medication-taking behavior of patients with a history of acute coronary syndromes (ACS) for 4 classes of drugs and determine the relationship between self-reported adherence and patient characteristics. Consenting patients with the diagnosis of ACS were interviewed by telephone approximately 10 months after discharge. The survey elicited data characterizing the patient, current medication regimens, beliefs about drug therapy, reasons for discontinuing medications, and adherence. The survey included the Beliefs About Medicine Questionnaire providing 4 scales: Specific Necessity, Specific Concerns, General Harm, and General Overuse, and the Medication Adherence Scale (MAS). Multivariate regression was used to determine the independent variables with the strongest association to the MAS. A p value or =1 other person, and 42% indicating excellent or very good health. The percentage of patients continuing on medication at the time of the survey category ranged from 87.4% (aspirin) to 66.0% (angiotensin-converting enzyme inhibitors). Reasons for stopping medication included physician discontinuation or adverse effects. Of patients still on drug therapy, the mean MAS was 1.3 +/- 0.4, with 53.8% indicating nonadherence (score >1). The final regression model showed R(2) = 0.132 and included heart-related health status and Specific Necessity as significant predictor variables. After ACS, not all patients continue their drugs or take them exactly as prescribed. Determining beliefs about illness and medication may be helpful in developing interventions aimed at improving adherence.

    Systemic autoimmune diseases are themselves a relevant and independent risk factor for atherosclerosis and coronary ectasia. We describe a case of a 58-year-old Caucasian man who was admitted to our department for unstable angina. History of asthma, paranasal sinus abnormality, and peripheral eosinophilia given a high suspicion of Churg-Strauss syndrome (CSS). Diagnosis was performed with 5 of the 6 American College of Rheumatology criteria. The knowledge that CSS is often associated with significant coronary artery involvement and the persistence of chest pain led us to performing immediately a coronary angiography. Coronary angiography showed diffuse ectasic lesions, chronic occlusion of left anterior descending artery with homocoronary collateral circulation from left circumflex artery and subocclusive stenosis in the proximal tract of posterior descending artery. The early recognition of CSS, an aggressive invasive diagnostic approach, and an early appropriate therapy are important to prevent the progressive and permanent cardiac damage in these patients. In the setting of a multidisciplinary approach, careful cardiac assessment is an essential step in CSS, even in mildly symptomatic patients. Copyright © 2015 Cardiological Society of India.

On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50% determined through coronary angiography is not well described. Methods: We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown on angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex.Results: Most patients (81.7% were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%, dyslipidemia (47.5%, and diabetes (37.7%. In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent.

    Arterial hypertension is an established risk factor for acute coronary syndrome (ACS). Multidetector computed tomography (MDCT) is an accurate and less invasive technique for assessment of the degree of coronary artery luminal narrowing and characterization of coronary atherosclerosis. We therefore aimed to investigate the predictive power of MDCT for future ACS events and compared with traditional parameters in patients with hypertension. One hundred and thirty-four patients (93 men, mean age 70±11 years) with hypertension underwent MDCT for evaluation of coronary artery disease. MDCT analysis focused on the presence of plaques, the degree of stenosis, and the plaque characteristics. Traditional parameters included Framingham risk score, carotid intima-media thickness, and left ventricular mass index. During a mean follow-up of 39±10 months, ACS events occurred in 10 patients, including myocardial infarction (n=3) and unstable angina (n=7). Multivariate analysis identified total number of low attenuation plaques as an independent predictor of ACS events (p<0.001). We demonstrated that non-obstructive low attenuation coronary plaques on MDCT predicted more accurately future ACS events in patients with hypertension than traditional parameters. (author)

    Although the elderly comprise the majority of acute coronary syndrome (ACS) patients, limited data exist on major adverse cardiovascular events (MACEs) and quality of life (QoL). To study MACEs and QoL prospectively in ACS patients >70years referred for coronary angiography. A prospective observational study that included ACS patients >70years undergoing coronary angiography. The outcomes were MACEs and QoL 3years after inclusion. MACEs were defined as death, recurrent ACS, new-onset of heart failure and repeated revascularization by coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). A QoL questionnaire was completed by the patients along with a physical examination and a personal interview at the 3-year follow-up. Multivariate analysis was performed to identify the predictors for MACEs. In total, 138 patients (mean age 78.8±3.8years) with ACS were included in the study. Mean follow-up was 1196±296days. In all, 42% of the patients had MACEs and 25% had post-ACS heart failure. The mortality rate was 11%. After adjusting for significant cardiovascular risk factors, the following factors were significantly associated with MACEs: Age, high-sensitive troponin T (hsTNT), use of diuretics and reduced left ventricular ejection fraction (LVEF). Furthermore, the QoL evaluated with SF-36 in survivors from ACS at the end of study was similar to the QoL in an age-matched healthy Swedish population. In this prospective study on elderly ACS patients MACEs still occurred in 42% of the cases (despite low mortality and good QoL), with post-ACS heart failure as the most important event.

    The genetic predisposition toward suicidal ideation has been explored to identify subgroups at high risk and to prevent suicide. Acute coronary syndrome (ACS) is associated with an increased risk of suicide, but few studies have explored the genetic predisposition toward suicide in ACS populations. Therefore, this longitudinal study explored the genetic predisposition toward suicidal ideation in ACS patients. In total, of 969 patients within 2 weeks after ACS, 711 were followed at 1 year after ACS. Suicidal ideation was evaluated with the relevant items on the Montgomery-Åsberg Depression Rating Scale. Ten genetic polymorphisms associated with serotonergic systems, neurotrophic factors, carbon metabolism, and inflammatory cytokines were examined. Associations between genetic polymorphisms and suicidal ideation within 2 weeks and 1 year of ACS were investigated using logistic regression models. The 5-HTTLPR s allele was significantly associated with suicidal ideation within 2 weeks of ACS after adjusting for covariates and after the Bonferroni correction. TNF-α -308 G/A , IL-1β -511 C/T , and IL-1β + 3953C/T were significantly associated with suicidal ideation within 2 weeks after ACS, but these associations did not reach significance after the Bonferroni correction in unadjusted analyses and after adjusting for covariance. However, no significant association between genetic polymorphisms and suicidal ideation was found at 1 year. Genetic predisposition, 5-HTTLPR s allele in particular, may confer susceptibility to suicidal ideation in ACS patients during the acute phase of ACS.

    Oxidative stress plays a major role in the development of atherosclerosis. However, the relationship between oxidative stress and complexity and intensity of coronary artery disease is less clear. The aim of this study is to assess the relationship between oxidative stress markers and the complexity and intensity of coronary artery disease in patients with acute coronary syndrome (ACS). Sixty-seven consecutive patients with an early phase of ACS (=22). Likewise patients were divided into two CAD severity groups according to the median Gensini score of 64: less intensive CAD with Gensini score (=64. Blood samples were taken in 1 hour within administration in order to measure total oxidative status (TOS) and total antioxidant capacity (TAC) levels determined by Erel method. Oxidative stress index (OSI) was calculated by TOS /TAC. There was no significant difference between the two SYNTAX groups for oxidative stress markers. Median TOS and OSI values were significantly high in the intensive CAD group (p=0.005, p=0.04, respectively). The Gensini score was positively correlated with TOS and OSI (p=0.003, p=0.02, respectively). Oxidative stress markers may be considered supportive laboratory parameters related to CAD intensity but not complexity in ACS patients.

    The objective of this study was to determine the direct and indirect costs of acute coronary syndromes (ACS) alone and with common cardiovascular comorbidities. A retrospective analysis was conducted using the Medical Expenditure Panel Survey from 1998 to 2009. Four mutually exclusive cohorts were evaluated: ACS only, ACS with atrial fibrillation (AF), ACS with heart failure (HF), and ACS with both conditions. Direct costs were calculated for all-cause and cardiovascular-related health care resource utilization. Indirect costs were determined from productivity losses from missed days of work. Regression analysis was developed for each outcome controlling for age, US census region, insurance coverage, sex, race, ethnicity, education attainment, family income, and comorbidity burden. A negative binomial regression model was used for health care utilization variables. A Tobit model was utilized for health care costs and productivity loss variables. Total health care costs were greatest for those with ACS and both AF and HF ($38,484±5,191) followed by ACS with HF ($32,871±2,853), ACS with AF ($25,192±2,253), and ACS only ($17,954±563). Compared with the ACS only cohort, the mean all-cause adjusted health care costs associated with ACS with AF, ACS with HF, and ACS with AF and HF were $5,073 (95% confidence interval [CI] 719-9,427), $11,297 (95% CI 5,610-16,985), and $15,761 (95% CI 4,784-26,738) higher, respectively. Average wage losses associated with ACS with and without AF and/or HF amounted to $5,266 (95% CI -7,765, -2,767), when compared with patients without these conditions. ACS imposes a significant economic burden at both the individual and society level, particularly when with comorbid AF and HF.

    Circulating endothelial progenitor cells (EPCs) are related to endothelial function and progression of coronary artery disease. There is evidence of decreased numbers of circulating EPCs in patients with a current episode of major depression. We investigated the relationships between the level of circulating EPCs and depression and anxiety in patients with acute coronary syndrome (ACS). Patients with ACS admitted to three Cardiology Intensive Care Units were evaluated by the SCID-I to determine the presence of lifetime and/or current mood and anxiety disorders according to DSM-IV criteria. The EPCs were defined as CD133(+) CD34(+) KDR(+) and evaluated by flow cytometry. All patients underwent standardized cardiological and psychopathological evaluations. Parametric and nonparametric statistical tests were performed where appropriate. Out of 111 ACS patients, 57 were found to have a DSM-IV lifetime or current mood or anxiety disorder at the time of the inclusion in the study. The ACS group with mood or anxiety disorders showed a significant decrease in circulating EPC number compared with ACS patients without affective disorders. In addition, EPC levels correlated negatively with severity of depression and anxiety at index ACS episode. The current study indicates that EPCs circulate in decreased numbers in ACS patients with depression or anxiety and, therefore, contribute to explore new perspectives in the pathophysiology of the association between cardiovascular disorders and affective disorders.

    We tested the hypothesis that lower blood omega-3 (omega-3) fatty acids (FAs) and/or higher trans FAs are associated with the risk of an acute coronary syndrome (ACS). Higher levels of omega-3 FA have been associated with decreased risk of sudden cardiac death. However, their association with ACS risk is unclear. Although higher self-reported intakes of trans FAs have been linked to increased coronary risk, the association between blood levels of trans FA and ACS risk is also unknown. We analyzed the FA composition of whole blood from 94 subjects with ACS and 94 age-, gender-, and race-matched controls. Omega-3 and trans FA associations with ACS were assessed using multivariable models after adjusting for smoking status, alcohol use, diabetes, body mass index, serum lipids, and history of myocardial infarction or revascularization. Subjects' mean age was 47 years, 54% were men, and 80% were Caucasian. Whole blood long-chain omega-3 FA (eicosapentaenoic acid [EPA] plus docosahexaenoic acid [DHA]) content was 29% lower in patients than in controls (1.7 +/- 0.9% vs 2.4 +/- 1.4%, p ACS, but higher blood trans FA content is not. Blood EPA + DHA may serve as a new, modifiable risk factor for ACS.

    Early risk stratification in patients with non-ST elevation acute coronary syndromes (NSTE-ACS) is important since the benefit from more aggressive and costly treatment strategies is proportional to the risk of adverse clinical events. In the present study we assessed whether hybrid single photon emission computed tomography (SPECT)/coronary computed tomography angiography (CCTA) technology could be an appropriate tool in stratifying patients with NSTE-ACS. SPECT/CCTA was performed in 90 consecutive patients with NSTE-ACS. The Thrombolysis in Myocardial Infarction risk score (TIMI-RS) was used to classify patients as low- or high-risk. Imaging was performed using SPECT/CCTA to identify haemodynamically significant lesions defined as >50% stenosis on CCTA with a reversible perfusion defect on SPECT in the corresponding territory. CCTA demonstrated at least one lesion with >50% stenosis in 35 of 40 high-risk patients (87%) as compared to 14 of 50 low-risk patients (35%; TIMI-RS <3; p <0.0001). Of the 40 high-risk and 50 (16%) low-risk TIMI-RS patients, 16 (40%) and 8 (16%), respectively, had haemodynamically significant lesions (p = 0.01). Patients defined as high-risk by a high TIMI-RS, a positive CCTA scan or both (n = 45) resulted in a sensitivity of 95%, specificity of 49%, PPV of 35% and NPV of 97% for having haemodynamically significant coronary lesions. Those with normal perfusion were spared revascularization procedures, regardless of their TIMI-RS. Noninvasive assessment of coronary artery disease by SPECT/CCTA may play an important role in risk stratification of patients with NSTE-ACS by better identifying the subgroup requiring intervention.

    Full Text Available The final most common pathway for the majority of coronary artery disease is occlusion of a coronary vessel. Under normal conditions, antithrombin III (AT III, protein C, and protein S as an active protein C cofactor, are natural anticoagulants (hemostatic control that balances procoagulant activity (thrombin antithrombin complex balance to prevent thrombosis. If the condition becomes unbalanced, natural anticoagulants and the procoagulants can lead to thrombosis. Thirty subjects with acute coronary syndrome (ACS were studied for the incidence of antithrombin III (AT III, protein C, and protein S deficiencies, and the result were compare to the control group. Among patients with ACS, the frequency of distribution of AT-III with activity < 75% were 23,3% (7 of 30, and only 6,7% ( 2 of 30 in control subject. No one of the 30 control subject have protein C activity deficient, in ACS with activity < 70% were 13,3% (4 of 30. Fifteen out of the 30 (50% control subjects had protein S activity deficiency, while protein S deficiency activity < 70% was found 73.3.% (22 out of 30. On linear regression, the deterministic coefficient of AT-III activity deficiency to the development ACS was 13,25 %, and the deterministic coefficient of protein C activity deficient to the development of ACS was 9,06 %. The cut-off point for AT-III without protein S deficiency expected to contribute to the development of vessel disease was 45%. On discriminant analysis, protein C activity deficiency posed a risk for ACS of 4,5 greater than non deficient subjects, and AT-III activity deficiency posed a risk for ACS of 3,5 times greater than non deficient subjects. On binary logistic regression, protein S activity acted only as a reinforcing factor of AT-III activity deficiency in the development of ACS. Protein C and AT III deficiency can trigger ACS, with determinant coefficients of 9,06% and 13,25% respectively. Low levels of protein C posed a greater risk of

    Few data exist on temporal evolution of antithrombotic agent use in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) in Italy. We sought to compare data from the most recent prospective, multicenter, nationwide registries conducted in Italy, namely EYESHOT and SCOPE. EYESHOT enrolled 2585 consecutive ACS patients, both ST-segment elevation myocardial infarction (STEMI) and non-ST elevation ACS (NSTE-ACS), admitted to 203 Italian coronary care units over a 3-week period (2-22 Dec 2013 and 27 Jan-16 Feb 2014). Among patients enrolled in EYESHOT, 1755 (67.9%) underwent PCI (52.6% with STEMI and 47.4% with NSTE-ACS). In the SCOPE registry, a total of 1363 patients undergoing PCI were enrolled over 3 months (15 Feb-15 Apr 2016) in 39 Italian cath lab centers at medium to high PCI volume: 331 (24.3%) with a diagnosis of STEMI and 1032 (75.7%) with a diagnosis of NSTE-ACS. Over 2 years, the use of clopidogrel in the cath lab significantly decreased (from 11% to 8% in STEMI; p=0.06 and from 9% to 5% in NSTE-ACS; p=0.0002), while the administration of ticagrelor dramatically increased (from 14% to 37%; pSCOPE registries, a significant increase in the use of novel P2Y12 receptor inhibitors was observed, both at the time of PCI and at discharge.

  20. Contemporary Management of Coronary Artery Disease and Acute Coronary Syndrome in Patients with Chronic Kidney Disease and End-Stage Renal Disease

    Huang, Chin-Chou; Chen, Jaw-Wen

    2013-01-01

    Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have emerged as a worldwide public health problem. Due to the remarkably higher incidence and prevalence of this chronic disease in Taiwan than in other countries, CKD/ESRD has contributed to a significant health burden in Taiwan. Patients with CKD/ESRD have an increased risk of coronary artery disease (CAD) and acute coronary syndrome (ACS) compared to the normal population. Patients with ACS alone can present differently than patients with ACS and CKD/ESRD. Also, due to the lower prevalence of chest pain and ST-segment elevation, CKD/ESRD patients were more difficult to diagnose than other patients. Furthermore, whether advances in ACS management with medical therapy and an early invasive approach could improve patient outcomes with CKD/ESRD is not known. The use of antiplatelets such as aspirin and other antithrombotic agents might reduce the incidence of ACS or stroke in CKD patients. However, such use could also increase bleeding risk and even increase the likelihood of mortality, especially in dialysis patients. While recent clinical data suggest the potential benefit of aggressive management with coronary intervention for CAD and ACS in this category of patients, further clinical studies are still indicated for the proper medical strategy and revascularization therapy to improve the outcomes of CAD and ACS in CKD/ESRD patients, both in Taiwan and worldwide.

    Full Text Available Background. Acute coronary syndrome (ACS can complicate acute ischemic stroke, causing significant morbidity and mortality. To date, literatures that describe poststroke acute coronary syndrome and its morbidity and mortality burden are lacking. Methods. This is a single center, retrospective study where clinical characteristics, cardiac evaluation, and management of patients with suspected poststroke ACS were compared and analyzed for their association with inpatient mortality and 1-year all-cause mortality. Results. Of the 82 patients, 32% had chest pain and 88% had ischemic ECG changes; mean peak troponin level was 18, and mean ejection fraction was 40%. The medical management group had older individuals (73 versus 67 years, p<0.05, lower mean peak troponin levels (12 versus 49, p<0.05, and lower mean length of stay (12 versus 25 days, p<0.05 compared to those who underwent stent or CABG. Troponin levels were significantly associated with 1-year all-cause mortality. Conclusion. Age and troponin level appear to play a role in the current clinical decision making for patient with suspected poststroke ACS. Troponin level appears to significantly correlate with 1-year all-cause mortality. In the management of poststroke acute coronary syndrome, optimal medical therapy had similar inpatient and all-cause mortality compared to PCI and/or CABG.

    Diabetes mellitus is an independent risk factor for cardiovascular disease. To compare the efficacy of devices for continuous glucose monitoring and capillary glucose monitoring in hospitalized patients with acute coronary syndrome using the following parameters: time to achieve normoglycemia, period of time in normoglycemia, and episodes of hypoglycemia. We performed a pilot, non-randomized, unblinded clinical trial that included 16 patients with acute coronary artery syndrome, a capillary or venous blood glucose ≥ 140 mg/dl, and treatment with a continuous infusion of fast acting human insulin. These patients were randomized into 2 groups: a conventional group, in which capillary measurement and recording as well as insulin adjustment were made every 4h, and an intervention group, in which measurement and recording as well as insulin adjustment were made every hour with a subcutaneous continuous monitoring system. Student's t-test was applied for mean differences and the X(2) test for qualitative variables. We observed a statistically significant difference in the mean time for achieving normoglycemia, favoring the conventional group with a P = 0.02. Continuous monitoring systems are as useful as capillary monitoring for achieving normoglycemia. Copyright © 2012 Instituto Nacional de Cardiología Ignacio Chávez.

Methods: A retrospective analysis was conducted using the Medical Expenditure Panel Survey from 1998 to 2009. Four mutually exclusive cohorts were evaluated: ACS only, ACS with atrial fibrillation (AF, ACS with heart failure (HF, and ACS with both conditions. Direct costs were calculated for all-cause and cardiovascular-related health care resource utilization. Indirect costs were determined from productivity losses from missed days of work. Regression analysis was developed for each outcome controlling for age, US census region, insurance coverage, sex, race, ethnicity, education attainment, family income, and comorbidity burden. A negative binomial regression model was used for health care utilization variables. A Tobit model was utilized for health care costs and productivity loss variables. Results: Total health care costs were greatest for those with ACS and both AF and HF ($38,484±5,191 followed by ACS with HF ($32,871±2,853, ACS with AF ($25,192±2,253, and ACS only ($17,954±563. Compared with the ACS only cohort, the mean all-cause adjusted health care costs associated with ACS with AF, ACS with HF, and ACS with AF and HF were $5,073 (95% confidence interval [CI] 719–9,427, $11,297 (95% CI 5,610–16,985, and $15,761 (95% CI 4,784–26,738 higher, respectively. Average wage losses associated with ACS with and without AF and/or HF amounted to $5,266 (95% CI -7,765, -2,767, when compared with patients

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

    This study investigated the interaction effects of meteorological factors and air pollutants on the onset of acute coronary syndrome (ACS). Data of ACS patients were obtained from the Taiwan ACS Full Spectrum Registry and comprised 3164 patients with a definite onset date during the period October 2008 and January 2010 at 39 hospitals. Meteorological conditions and air pollutant concentrations at the 39 locations during the 488-day period were obtained. Time-lag Poisson and logistic regression were used to explore their association with ACS incidence. One-day lag atmospheric pressure (AP), humidity, particulate matter (PM2.5, and PM10), and carbon monoxide (CO) all had significant interaction effects with temperature on ACS occurrence. Days on which high temperatures (>26 °C) and low AP (<1009 hPa) occurred the previous day were associated with a greater likelihood of increased incidence of developing ACS. Typhoon Morakot was an example of high temperature with extremely low AP associated with higher ACS incidence than the daily average. Combinations of high concentrations of PM or CO with low temperatures (<21 °C) and high humidity levels with low temperatures were also associated with increased incidence of ACS. Atmospheric pollution and weather factors have synergistic effects on the incidence of ACS.

    Full Text Available BACKGROUND It is observed that anaemia is a common problem in patients hospitalised for acute coronary syndromes. There have been reports in worldwide studies of an association between anaemia and poor prognosis in patients with Acute Coronary Syndromes (ACS. MATERIALS AND METHODS All consecutive patients having ST-elevation myocardial infarction, non-ST elevation myocardial infarction and unstable angina who were admitted in medicine ward, Medicine Intensive Care Unit (MICU, Cardiology Department (CRD, Cardiovascular and Thoracic Surgery (CVTS Department and incidentally found in other departments of Acharya Vinoba Bhave Rural Hospital admitted from 1st November 2014 to 31st December 2015 at AVBRH. Total 200 patients were included in the study. RESULTS Our study showed an association between haemoglobin levels and mean age (p=0.0001, gender (p=0.0001, risk factors like smoking (p=0.035, tobacco (p=0.001 and Killip’s class I (p=0.0001, III (p=0.0001 and IV (p=0.0001. On distribution of the MACE’s during hospital stay stratified with Hb levels, the results of analysis by Chi-square test showed that there were statistically significant differences at various haemoglobin levels in MACE’s as post-infarction angina, heart failure, VT/VF and death (p<0.05 for all. On distribution of the MACE’s during follow up on 30th day and on 180th day stratified with Hb levels, the results of analysis by Chi-square test showed that there were statistically significant differences at various haemoglobin levels in MACE’s as post-infarction angina, re-infarction, heart failure, VT/VF and death (p<0.05 for all. CONCLUSION To conclude our study results, it was found during the study that anaemia as an important risk factor was strongly associated with major adverse outcomes in patients with ACS. Our study suggested that there was a statistically significant correlation between the low Hb levels and MACE’s (post-infarction angina, re-infarction, heart

    Acute Coronary Syndrome (ACS), is a serious threat to people's health, and life, and in recent years, the incidence has increased yearly. This study was to propose the hypothesis of "endogenous collateral wind" based on the patho-mechanism of thrombogenesis complicated by ruptured plaque on ACS, and the theory of traditional Chinese medicine. Through successful coronary angiography (CAG), and intravascular ultrasound (IVUS), patients with coronary artery disease were made the differential diagnosis such as blood stasis, blood stasis due to phlegm obstruction, and endogenous collateral wind. The levels of plasma inflammatory marker were measured to study on the characteristics of "endogenous collateral wind". Luo heng dripping pills with promoting blood circulation to expel wind-evil, and remove wetness were made based on the hypothesis of "endogenous collateral wind" on ACS. Patients with unstable angina were randomly divided into 3, groups based on therapeutic methods: conventional therapy group, Luo Heng dripping pills group and Tongxinluo caps. Differences among groups were compared. There were great changes in number and degree of coronary arteriostenosis confirmed by CAG, the types of ACC/AHA lesion and Levin lesion confirmed by CAG, remodeling index, positive or negative remodeling percentage measured by IVUS, the plasma levels of plasma inflammatory marker measured by ELLSA in the patients with endogenous collateral wind, compared with patients with blood stasis and blood stasis due to phlegm obstruction. The total effective rate of improved angina in Luo Heng dripping pills group was significantly higher than those in other two groups. The levels of plasma inflammatory marker were significantly lower in Luo Heng dripping pills group. There were some pathological basis which were found about the hypothesis of "endogenous collateral wind" on acute coronary syndrome. It provided evidences for patients with coronary artery disease treated by medicines with

    The objective was to determine the association of four clinical risk scores and coronary plaque burden as detected by computed tomography (CT) with the outcome of acute coronary syndrome (ACS) in patients with acute chest pain. The hypothesis was that the combination of risk scores and plaque burden improved the discriminatory capacity for the diagnosis of ACS. The study was a subanalysis of the Rule Out Myocardial Infarction Using Computer-Assisted Tomography (ROMICAT) trial-a prospective observational cohort study. The authors enrolled patients presenting to the emergency department (ED) with a chief complaint of acute chest pain, inconclusive initial evaluation (negative biomarkers, nondiagnostic electrocardiogram [ECG]), and no history of coronary artery disease (CAD). Patients underwent contrast-enhanced 64-multidetector-row cardiac CT and received standard clinical care (serial ECG, cardiac biomarkers, and subsequent diagnostic testing, such as exercise treadmill testing, nuclear stress perfusion imaging, and/or invasive coronary angiography), as deemed clinically appropriate. The clinical providers were blinded to CT results. The chest pain score was calculated and the results were dichotomized to ≥10 (high-risk) and modeling was performed to examine the association of risk scores and coronary plaque burden to the outcome of ACS. Unadjusted models were individually fitted for the coronary plaque burden and for Goldman, Sanchis, TIMI, and chest pain scores. In adjusted analyses, the authors tested whether the association between risk scores and ACS persisted after controlling for the coronary plaque burden. The prognostic discriminatory capacity of the risk scores and plaque burden for ACS was assessed using c-statistics. The differences in area under the receiver-operating characteristic curve (AUC) and c-statistics were tested by performing the -2 log likelihood ratio test of nested models. A p value capacity for the diagnosis of ACS. Plaque burden was

    In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS. To monitor the effectiveness and safety of cardiac rehabilitation in

    We investigated the utility of noninvasive hemodynamic assessment in the identification of high-risk plaques that caused subsequent acute coronary syndrome (ACS). ACS is a critical event that impacts the prognosis of patients with coronary artery disease. However, the role of hemodynamic factors in the development of ACS is not well-known. Seventy-two patients with clearly documented ACS and available coronary computed tomographic angiography (CTA) acquired between 1 month and 2 years before the development of ACS were included. In 66 culprit and 150 nonculprit lesions as a case-control design, the presence of adverse plaque characteristics (APC) was assessed and hemodynamic parameters (fractional flow reserve derived by coronary computed tomographic angiography [FFR CT ], change in FFR CT across the lesion [△FFR CT ], wall shear stress [WSS], and axial plaque stress) were analyzed using computational fluid dynamics. The best cut-off values for FFR CT , △FFR CT , WSS, and axial plaque stress were used to define the presence of adverse hemodynamic characteristics (AHC). The incremental discriminant and reclassification abilities for ACS prediction were compared among 3 models (model 1: percent diameter stenosis [%DS] and lesion length, model 2: model 1 + APC, and model 3: model 2 + AHC). The culprit lesions showed higher %DS (55.5 ± 15.4% vs. 43.1 ± 15.0%; p stress than nonculprit lesions (all p values statistic [c-index] 0.789 vs. 0.747; p = 0.014) and reclassification abilities (category-free net reclassification index 0.287; p = 0.047; relative integrated discrimination improvement 0.368; p < 0.001) than model 2. Lesions with both APC and AHC showed significantly higher risk of the culprit for subsequent ACS than those with no APC/AHC (hazard ratio: 11.75; 95% confidence interval: 2.85 to 48.51; p = 0.001) and with either APC or AHC (hazard ratio: 3.22; 95% confidence interval: 1.86 to 5.55; p < 0.001).

    Authors have found that the effect in the title (DEE) exists in cardiac CT images due to the contrasting agent used for percutaneous coronary intervention (PCI) done shortly after the onset of acute coronary syndrome (ACS). To confirm the finding, they compared images of the cardiac CT and blood flow single photon emission computed tomography (SPECT) obtained several days after ACS. The cardiac CT images of 17 patients (M 15, F 2; average age 63.6 y) with ACS were obtained 20-30 min after the successfully attained emergent enhanced PCI, with the 4-row multi detector low CT (MDCT) machine Aquilion (Toshiba) in synchronization to R-R interval for processing to multiplanar reconstructed (MPR) images. Thereafter (5.5 days in average), myocardial SPECT was conducted with 99m Tc-tetrofosmin (740 MBq), of which images were also processed to MPR ones. The CT and SPECT images were compared in coronary arterial territories assigned to 17 segments in the left ventricle and to 20 areas in the Bull's-eye Map. Findings due to DEE in the former CT images were confirmed well correspondent with the lesion found in the latter SPECT, indicating that DEE is a useful tool for evaluation of ACS severity. (R.T.)

    Full Text Available The receptor of advanced glycation end products (RAGE and its ligands are linked to the pathogenesis of coronary artery disease (CAD, and circulating soluble receptor of advanced glycation end products (sRAGE, reflecting the RAGE activity, is suggested as a potential biomarker. Elevated sRAGE levels are reported in relation to acute ischemia and this review focuses on the role of sRAGE as a biomarker for the acute coronary syndrome (ACS. The current studies demonstrated that sRAGE levels are elevated in relation to ACS, however during a very narrow time period, indicating that the time of sampling needs attention. Interestingly, activation of RAGE may influence the pathogenesis and reflection in sRAGE levels in acute and stable CAD differently.

    Full Text Available Kawasaki syndrome is an acute systemic vasculitis of unknown etiology, which mainly affects children within the first 5 years of fife. At the present time, Kawasaki syndrome is recognized to be a leading cause of acquired organic heart diseases in children, which may result in coronary heart disease, myocardial infarction, and sudden death in children and young people. Most complications are associated with the cardiovascular system, with coronary artery changes in particular. Transthoracic echocardiography, which, besides coronary artery assessment, makes it possible to evaluate right and left ventricular systolic and diastolic functions and to study the cardiac valves and changes in pericardial effusion, is a major technique in Kawasaki syndrome. The paper outlines an update on the epidemiology, etiology, pathogenetic mechanisms, and pathomorphology of Kawasaki syndrome and considers possible coronary and noncoronary changes, outcomes, and clinical manifestations.

    Full text: In the cardiac emergency department, a number of patients present with acute chest pain. In case of non diagnostic ECG and enzymes, accurately categorizing the patient in high and low probability is difficult. Aim of study was to evaluate the role of resting myocardial perfusion imaging (MPI) in patients with acute coronary syndrome (ACS) and then to compare the results with subsequent stress imaging. Material and Methods. A total of 34 patients were selected for the study, which were divided into three groups on the basis of respective probabilities of having ACS. This probability was decided on the basis of nature of chest pain, ECG findings, enzymes levels, and age and sex. Arbitrary score was given to patient's condition. This score ranged from 1 to 14. Patients with score between 1-6 were assigned low probability, from 7-10 were assigned intermediate probability and patients having score greater than 11 were placed in high probability groups. Patients in the low and intermediate probability groups were injected with Tc 99 m- MIBI within 6 hours of onset of chest pain and were undergone resting myocardial perfusion imaging (MPI) 3 to five hours after injection.. Imaging in high probability group was performed at discharge. Four weeks after the acute event all the patients underwent stress myocardial perfusion imaging. Results: All patients (100%) with low probability of ACS (n=10) showed negative resting scans. On stress MPI two patients (20%) showed new defects. Patient with high probability of ACS (n=12), all were positive 100% on resting MPI. On stress MPI, three showed (25%) no change from rest MPI, while nine patients (75%) showed augmentation of defects and four out of these nine patients (33%) also showed new perfusion defects. Patients with intermediate probability of ACS (n=12), three showed positive rest MPI (25%). On stress MPI out of these three cases, one showed (8%) no change from rest MPI and two showed (17%) augmentation of defect

    Variations in care and outcomes by sex in patients with acute coronary syndrome (ACS) have been reported worldwide. The aims of this study are to describe ACS management according to sex in China and the effects of a quality improvement program in Chinese male and female ACS patients. Clinical Pathways for Acute Coronary Syndromes - Phase 2 (CPACS-2) was a cluster randomized trial to test whether a clinical pathways-based intervention would improve ACS management in China. The study enrolled 15,141 hospitalized patients [4631 (30.6%) were women] from 75 hospitals throughout China between October 2007 and August 2010. The intervention included clinical pathway implementation and performance measurement using standardized indicators with 6 monthly audit-feedback cycles. Eight key performance indicators reflecting in hospital management of ACS were measured. After adjustment for differences in patient characteristics and comorbidities at presentation, women were significantly less likely to undergo coronary angiography when indicated (RR 0.88 [0.85 to 0.92], Pquality improvement initiative by sex. Sex disparities were apparent in some key quality of care indicators for patients with suspected with ACS presenting to hospitals in China.

    The natriuretic hormones are a family of vasoactive peptides that can be measured circulating in the blood. Because they serve as markers of hemodynamic stress, the major focus of the use of natriuretic peptide levels [predominantly B-type natriuretic peptide (BNP) and N-terminal (NT)-pro-BNP] has been as an aid to the clinical diagnosis and management of congestive heart failure (CHF). Recently, however, the measurement of natriuretic peptides in the acute coronary syndromes (ACS) has been shown to provide information complementary to traditional biomarkers (of necrosis) such as cardiac troponins and creatine kinase (CK). Studies in several types of acute coronary syndromes [ST-segment elevation myocardial infarction (STEMI), non-ST elevation MI (NSTEMI) and unstable angina (UA)] have shown that elevated levels of natriuretic peptides are independently associated with adverse outcomes, particularly mortality. Additional information is obtained from the use natriuretic peptides in combination with other markers of risk including biomarkers of necrosis and inflammation. This review will summarize the scientific rationale and clinical evidence supporting measurement of natriuretic peptides for risk stratification in acute coronary syndromes. Future research is needed to identify therapies of particular benefit for patients with ACS and natriuretic peptide elevation.

    Asymptomatic acute ischemic stroke (aAIS) following primary percutaneous coronary intervention (p-PCI) in patients with acute coronary syndrome (ACS) has not been studied in detail. Of 75 patients who underwent p-PCI, 26 (34.7%) developed aAIS as determined by diffusion-weighted magnetic resonance imaging (MRI). Including the approach to the coronary artery (via lower limb or right upper limb), 23 factors were compared between patients with (n=26) and without (n=49) aAIS. Age, hypertension, smoking, plasma glucose levels, Killip grade, right coronary artery (RCA) as culprit vessel, percutaneous coronary intervention (PCI) time, and the frequency of device insertion into the coronary artery differed in a statistically significant manner. However, multivariate analysis showed that the RCA (odds ratio 3.477) and the frequency of device insertion (1.375) were independent factors linked to the incidence of aAIS. Moreover, anterior or posterior location and left or right cerebral circulation of aAIS were equivalent in both approaches. Cranial MRI images following emergency PCI revealed that 34.7% of the patients with ACS had aAIS that might be caused by manipulating the catheter or devices in the ascending aorta, micro-air bubble embolism during injection, or micro-thrombus embolism derived from the ACS lesions during the PCI procedure.

  11. The "Acute coronary syndromes: consensus recommendations for translating knowledge into action" position statement is based on a false premise.

    2010-06-21

    Recent National Heart Foundation of Australia (NHFA) guidelines for management of acute coronary syndromes (ACS) recommend increasing the rates of early invasive management of ACS and providing equal access for all Australians to percutaneous coronary intervention (PCI) facilities. For patients with ACS managed in regional hospitals without PCI facilities, review of the evidence does not show unequivocal benefit of early routine PCI over selective PCI for patients with non-ST-segment-elevation ACS or ST-elevation myocardial infarction. The current pattern of transfer based on the NHFA guidelines is expensive and disruptive of patient care, as well as undermining regional health care services. Further increase in transfer rates and increases in PCI facilities would divert resources away from supporting the regional infrastructure needed to provide evidence-based therapies, without any evidence that lives would be saved.

    Full Text Available We describe the unexpected case of a 70-year-old man, with medical history of ischemic heart disease and surgery for aneurysm of abdominal aorta, who comes to the emergency department complaining of low-back pain without other symptoms or signs of organic failure. After a few hours we see a deterioration of physical conditions with pulmonary oedema, increase of blood pressure, changing in the ECG pattern, and worsening of left ventricular function with progressive increase of biomarkers for myocardial necrosis. So this pain has revealed the premature symptom of an acute coronary syndrome (ACS. After a short time a subsequent cardiac arrest complicates the clinical situation. After resuscitation, the patient undergoes successfully to coronary angiography and performed a percutaneous transluminal coronary angioplasty (PTCA.

    Most patients with acute coronary syndrome (ACS) are treated with statins, which reduce atherogenic triglyceride-rich lipoproteins. It is uncertain whether triglycerides predict risk after ACS on a background of statin treatment. This study examined the relationship of fasting triglyceride levels to outcomes after ACS in patients treated with statins. Long-term and short-term relationships of triglycerides to risk after ACS were examined in the dal-OUTCOMES trial and atorvastatin arm of the MIRACL (Myocardial Ischemia Reduction with Acute Cholesterol Lowering) trial, respectively. Analysis of dal-OUTCOMES included 15,817 patients (97% statin-treated) randomly assigned 4 to 12 weeks after ACS to treatment with dalcetrapib (a cholesteryl ester transfer protein inhibitor) or placebo and followed for a median 31 months. Analysis of MIRACL included 1,501 patients treated with atorvastatin 80 mg daily beginning 1 to 4 days after ACS and followed for 16 weeks. Fasting triglycerides at initial random assignment were related to risk of coronary heart disease death, nonfatal myocardial infarction, stroke, and unstable angina in models adjusted for age, sex, hypertension, smoking, diabetes, high-density lipoprotein cholesterol, and body mass index. Fasting triglyceride levels were associated with both long-term and short-term risk after ACS. In dal-OUTCOMES, long-term risk increased across quintiles of baseline triglycerides (p175/≤80 mg/dl) was 1.61 (95% confidence interval: 1.34 to 1.94). There was no interaction of triglycerides and treatment assignment on the primary outcome. In the atorvastatin group of MIRACL, short-term risk increased across tertiles of baseline triglycerides (p=0.03), with a hazard ratio of 1.50 [corrected] (95% confidence interval: 1.05 to 2.15) in highest/lowest tertiles (>195/≤135 mg/dl). The relationship of triglycerides to risk was independent of low-density lipoprotein cholesterol in both studies. Among patients with ACS treated effectively

    The term acute coronary syndrome (ACS) encompasses a range of thrombotic coronary artery diseases, including unstable angina (UA) and both ST-segment elevation (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Bio markers play an important role in the diagnosis of non-ST-elevation ACS (NSTE-ACS) including unstable angina and non-STEMI. Among these, cardiac troponin and creatine phosphokinase myocardial band appeared to be the most sensitive and specific markers of myocardial injury. The important role of inflammatory processes in the development and progression of atherosclerosis has been clearly established. Different circulating inflammatory bio markers indicating the instability of atherosclerotic plaque have been identified and serve as diagnostic tools for the identification of patients with unstable angina or acute myocardial infarction and to identify risk patients. The present study was carried out on twenty patients with (NSTE-ACS). The level of serum troponin I (cTnI), creatine phosphokinase-total (CPK-T), myocardial band of creatine phosphokinase (CPK-MB), pregnancy associated plasma protein-A (PAPP-A) and highly sensitive C-reactive protein (hsCRP) were determined. The results showed increase in the level of cardiac bio markers (cTnI, CPK-MB, CPK-T) and inflammatory markers (PAPP-A, hsCRP). It could be concluded that the increase in inflammatory markers correlate especially PAPP-A in NSTE-ACS with the increase of cardiac bio markers

    Full Text Available BACKGROUND: Neopterin is a soluble biomarker of monocyte activation and its increased concentration might be expressed in atherosclerosis. Until recently, there has been lacking of information on the prognostic role of neopterin in acute coronary syndromes (ACS. The study was aimed at measuring the associations between elevated serum neopterin and increased risk of cardiovascular (CV events in ACS. METHODS: This was a prospective cohort study, recruited 71 ACS patients from January 31 through August 31, 2007 in Sanglah Hospital of Udayana School of Medicine, Denpasar, Bali. Cardiovascular events, such as: CV death, recurrent myocardial infarction, stroke and recurrent myocardial ischemia were previously defined. Relative risk and survival rate were measured successively by Cox proportional model and Kaplan-Meier curve. RESULTS: Of 71 ACS patients aged 56.8±9.5 years, 21 (29.5% subjects underwent CV events. Overall mean followup was 151.6 (95% CI: 129.7-173.5 days. Baseline characteristic were similarly distributed between groups with the highest quartile neopterin level (≥14.7 nmol/L than those with lowest quartile (≤6.2 nmol/L. Patients with the highest quartile had the worst survival curve than those with the lowest quartile (log-rank test; p=0.047. On Cox proportional model, relative risk of highest quartile group was 5.84 (95% CI: 1.19-28.47; p=0.029 compared to lowest quartile, after being adjusted with other predictors. CONCLUSIONS: Elevated serum neopterin is associated with increased risk of CV events in acute coronary syndromes. KEYWORDS: neopterin, cardiovascular events, acute coronary syndromes.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    Among patients with acute chest pain, acute coronary syndrome (ACS) is seen only in a minority of the patients, which raises the question, whether it is possible to separate a group with a high risk of ACS for admission to a cardiac care unit (CCU) from those with a low risk who would be treated at an emergency department (ED). The aim of this study was to describe a risk stratification model for a Danish context. This was a historic prospective cohort study of patients with suspicion of ACS. The patient was defined as a low-risk patient and admitted to the ED if: 1) electrocardiogram (ECG) was normal, 2) the patient did not have persisting chest pain and 3) there was no history of ischaemic heart disease, heart failure or cardioverter defibrillator. Otherwise, patients were admitted to the CCU. The primary outcome was whether the ACS diagnosis was confirmed or rejected. We included a total of 488 patients with suspicion of ACS, 50% of whom were low-risk patients. 17% had a verified ACS; 10% of those in the low-risk group and 24% of those in the high-risk group (p = 0.0001). Among the verified ACS cases, 71% went primarily to the CCU. The odds ratio for an ACS if assigned to the high-risk group was 3.0. Allocation to the high-risk group, male gender and age above 60 years was associated with a higher risk of ACS. For patients fulfilling the high-risk definition, sensitivity was 71%, specificity 55%, negative predictive value 90% and positive predictive value 24% for an ACS. The model for stratification separated patients into two equal groups, allocated 71% of all ACS directly to the CCU and could not be improved by any of the additional factors examined. Further development of referral strategies for chest pain patients is required. none. not relevant.

    Acute coronary syndromes are a frequent manifestation of a coronary artery disease, usually being associated with chest pain and presenting as a medical emergency. Since a considerable number of patients with chest pain, however, have a non cardiac etiology of trier pain, properly triaging these patients represents a diagnostic challenge for physicians in the emergency department. As the available diagnostic procedures have limited accuracy, many different diagnostic strategies have been evaluated. Among these, radionuclide myocardial perfusion imaging (MPI) at rest or in combination with stress procedures has been investigated in many trails. MPI has been proven to be useful, especially in a patient population with a low to intermediate probability of an ischemic event. Perfusion scintigraphy has a high sensitivity in the detection of myocardial infarction and reveals an excellent negative predictive value, allowing a safe discharge strategy of patients with a negative scan result. Moreover, it enables risk stratification and provides incremental and independent prognostic information regarding short to long term future cardiac adverse events. Several cost effectiveness studies have shown that perfusion imaging leads to lower overall direct costs, mainly by a reduction of unnecessary hospital admissions and diagnostic angiograms, without worsening of the clinical outcome of these patients. As a possible study endpoint, myocardial perfusion imaging in the acute setting enables the quantification of salvaged myocardium and therefore the evaluation of treatment efficacy. Besides perfusion agents, several infarcts avid radiopharmaceuticals have been developed, which in part show promising results. However, larger randomized trials evaluating these tracers in clinical settings are needed to warrant routine clinical application

    We hypothesized that matrix metalloproteinase (MMP)-2, -9, and tissue inhibitor metalloproteinase-1, -2 (TIMP-1, -2) would be abnormal in diabetes and in acute coronary syndromes (ACS). We measured MMP-2, -9, and TIMP-1, -2 plasma levels in healthy subjects (controls), in type 2 diabetic patients, in nondiabetic patients with ACS (ACS) and in diabetic patients with ACS (DACS). We enrolled 165 controls, 181 diabetic patients, 78 ACS, and 46 DACS. We measured also BMI (body mass index), HbA(1c) (glycated hemoglobin) FPG (fasting plasma glucosa), FPI (fasting plasma insulin), HOMA index (homeostasis model assessment index), SBP (systolic blood pressure), DBP (diastolic blood pressure), TC (total cholesterol), LDL-C (low density lipoprotein cholesterol), HDL-C (high-density lipoprotein cholesterol), Tg (triglycerides), Lp(a) (lipoprotein(a)) PAI-1 (plasminogen activator inhibitor-1), Hct (homocysteine), Fg (fibrinogen), and hs-CRP (high-sensitivity C-reactive protein). A significant increase of BMI was observed in the diabetic group, in ACS and DACS patients compared to controls. A significant increase of SBP and DBP resulted in the diabetic and DACS groups, while only SBP improvement was present in ACS patients with respect to controls. A decrease in SBP and DBP was observed in the ACS group, while SBP variation was present in DACS patients compared to diabetics, and DBP increase was obtained in the DACS group with respect to ACS patients. TC, LDL-C, Tg, and Lp(a) increase was present in diabetics, while TC, Tg, and Lp(a) improvement was present in ACS and DACS patients with a significant decrease of HDL-C levels in diabetic, ACS, and DACS groups compared to controls. A decrease in LDL-C was obtained in ACS and DACS groups, while HDL-C increase was observed in these patients with respect to diabetics. Tg levels were higher in the DACS group compared to diabetics and ACS patients, respectively. Increases in PAI-1, Hct, Fg, and hs-CRP were present in diabetic and DACS

    2012-05-01

    Full Text Available Posttraumatic stress disorder (PTSD is related to acute coronary syndrome (ACS; i.e., myocardial infarction or unstable angina recurrence and poor post-ACS adherence to medical advice. Since risk perceptions are a primary motivator of adherence behaviors, we assessed the relationship of probable PTSD to ACS risk perceptions in hospitalized ACS patients (n= 420. Participants completed a brief PTSD screen 3-7 days post-ACS, and rated their 1-year ACS recurrence risk relative to other men or women their age. Most participants exhibited optimistic bias (mean recurrence risk estimate between average and below average. Further, participants who screened positive for current PTSD (n=15 showed significantly greater optimistic bias than those who screened negative (p< .05, after adjustment for demographics, ACS severity, medical comorbidities, depression, and self-confidence in their ability to control their heart disease. Clinicians should be aware that psychosocial factors, and PTSD in particular, may be associated with poor adherence to medical advice due to exaggerated optimistic bias in recurrence risk perceptions.

    A 42-year-old woman with a history of aspirin-induced asthma was admitted with severe chest pain. Emergency coronary angiography revealed coronary artery spasms. The administration of vasodilators did not suppress the anginal symptoms, and the differential white blood cell count continued to show eosinophilia. The patient's symptoms of aspirin-induced asthma, eosinophilia and other allergic states led to the diagnosis of Churg-Strauss syndrome (CSS). After starting betamethasone therapy, the eosinophilia and cardiac symptoms rapidly disappeared. Although coronary vasospasms related to CSS are rare, the present case suggests that a differential white blood cell count should be obtained in patients with refractory coronary vasospasms.

    Full Text Available Aim – to study adherence prior hospitalization, and the most important factors of adherence in hospitalized patients with a diagnosis of acute coronary syndrome (ACS. Materials and methods. This study included all patients admitted to the Cardiology Department of the Clinical Hospital № 2 Lyubertsy with a diagnosis of ACS. All the patients were asked to complete a questionnaire on assessing adherence during their stay in hospital. Results. Under obtain preliminary results (six months from the start of the study the study included 130 patients with ACS: 79 men and 51 women. Half of the patients (n = 61 are constantly observed by a doctor, and the other half almost did not seek for medical help. According to the Moriscos–Green test 71 persons (54.6 % were adherented to medical treatment, 55 patients were found to have low adherence to therapy. Only 42 patients, one-third of the survey participants took all drugs recommended by the doctor . Less than 9 % of patients hospitalized with diagnosis of ACS took statins, one third of patients were recommended to take aspirin. Primary cause of recommendations for medical therapy is forgetfulness (18.5 %, about 10 % of patients are afraid of the side effects of drugs. The main way to improve patient adherence to therapy was mentioned like information from the doctor about the possibility of improving the life and disease prognosis (62.3 %, quality of life, improving well-being(25.8 %, only 4 patients (3 % were totally unwilling to comply with medical recommendations. Conclusion. Specially designed questionnaire gave possibility to assess a number of facts (very low prescription of some of the main groups of cardiac drugs, high mortality identified in the study of the, and their possible causes. In addition to the personal factors of patients (forgetfulness, the main causes of poor adherence to treatment is the lack of awareness of patients about their illness, the possibilities of modern therapy

    Little is know about the outcomes of acute heart failure (AHF) with acute coronary syndrome (ACS-AHF), compared to those without ACS (NACS-AHF). We conducted a prospective registry of AHF patients involving 18 hospitals in Saudi Arabia between October 2009 and December 2010. In this sub-study, we compared the clinical correlates, management and hospital course, as well as short, and long-term outcomes between AHF patients with and without ACS. Of the 2609 AHF patients enrolled, 27.8 % presented with ACS. Compared to NACS-AHF patients, ACS-AHF patients were more likely to be old males (Mean age = 62.7 vs. 60.8 years, p = 0.003, and 73.8 % vs. 62.7 %, p coronary angiography and had higher prevalence of multi-vessel coronary artery disease (p < 0.001 for all comparisons). The unadjusted hospital and one-month mortality were higher in ACS-AHF patients (OR = 1.6 (1.2-2.2), p = 0.003 and 1.4 (1.0-1.9), p = 0.026 respectively). A significant interaction existed between the level of left ventricular ejection fraction and ACS-AHF status. After adjustment, ACS-AHF status was only significantly associated with hospital mortality (OR = 1.6 (1.1-2.4), p = 0.019). The three-years survival following hospital discharge was not different between the two groups. AHF patients presenting with ACS had worse hospital prognosis, and an equivalent long-term survival compared to AHF patients without ACS. These findings underscore the importance of timely recognition and management of AHF patients with concomitant ACS given their distinct presentation and underlying pathophysiology compared to other AHF patients.

    Background The incremental prognostic value of assessing the metabolic syndrome has been disputed. Little is known regarding its prognostic value in patients after an acute coronary syndrome. Design and methods The presence of metabolic syndrome (2005 International Diabetes Federation) was assessed at baseline in SOLID-TIMI 52, a trial of patients within 30 days of acute coronary syndrome (median follow-up 2.5 years). The primary endpoint was major coronary events (coronary heart disease death, myocardial infarction or urgent coronary revascularization). Results At baseline, 61.6% ( n = 7537) of patients met the definition of metabolic syndrome, 34.7% (n = 4247) had diabetes and 29.3% had both ( n = 3584). The presence of metabolic syndrome was associated with increased risk of major coronary events (adjusted hazard ratio (adjHR) 1.29, p metabolic syndrome was numerically but not significantly associated with the risk of major coronary events (adjHR 1.13, p = 0.06). Conversely, diabetes was a strong independent predictor of major coronary events in the absence of metabolic syndrome (adjHR 1.57, p metabolic syndrome identified patients at highest risk of adverse outcomes but the incremental value of metabolic syndrome was not significant relative to diabetes alone (adjHR 1.07, p = 0.54). Conclusions After acute coronary syndrome, diabetes is a strong and independent predictor of adverse outcomes. Assessment of the metabolic syndrome provides only marginal incremental value once the presence or absence of diabetes is established.

    The aim of this study was to report the frequency, patient and lesion-related characteristics, and outcomes of subclinical, nonculprit plaque ruptures in the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study. Plaque rupture and subsequent thrombosis is the most common cause of acute coronary syndrome (ACS). Secondary, subclinical, nonculprit plaque ruptures have been seen in both stable patients and patients with ACS; however, reports of the natural history of these secondary plaque ruptures are limited. After successful stenting in 697 patients with ACS, 3-vessel grayscale and intravascular ultrasound virtual histology (IVUS-VH) was performed in the proximal-mid segments of all 3 coronary arteries as part of a prospective multicenter study. Among 660 patients with complete IVUS data, 128 plaque ruptures were identified in 105 nonculprit lesions in 100 arteries from 93 patients (14.1%). Although the minimum lumen area (MLA) was similar, the plaque burden was significantly greater in nonculprit lesions with a plaque rupture compared with nonculprit lesions without a plaque rupture (66.0% [95% confidence interval: 64.5% to 67.4%] vs. 56.0% [95% confidence interval: 55.6% to 56.4%]; p PROSPECT]; NCT00180466).

    Western studies have suggested that emotional stress and distress impacted on the morbidity and mortality in people following acute coronary events. Symptoms of anxiety and depression have been associated with re-infarction and death, prolonged recovery and disability and depression may precipitate the client's low self-esteem. This study examined perceived anxiety, depression and self-esteem of Hong Kong Chinese clients diagnosed with acute coronary syndrome (ACS) over a 6-month period following hospital admission. To examine: A prospective, repeated measures design with measures taken on two occasions over a 6-month period; (1) within the 1st week of hospital admission following the onset of ACS and (2) at 6 months follow up. Convenient sample of 182 voluntary consented clients admitted with ACS to a major public hospital in Hong Kong who could communicate in Chinese, complete questionnaires, cognitive intact, and were haemodynamically stable and free from acute chest pain at the time of interview. Baseline data were obtained within 1 week after hospital admission. The follow-up data was collected 6 months after hospital discharge. The Chinese version of the Hospital Anxiety and Depression Scale (HADS), State Self-esteem Scale (SSES), and Rosenberg's Self-Esteem Scale (RSES) were used to assess anxiety and depression, state self-esteem, and trait self-esteem, respectively. Findings suggested gender differences in clients' perception in anxiety, depression and self-esteem. Improvements in clients' perception of these variables were evident over the 6-month period following their acute coronary events. The study confirmed the western notion that psychosocial problems are common among coronary clients and this also applies to Hong Kong Chinese diagnosed with ACS. Further studies to explore effective interventions to address these psychosocial issues are recommended.

    Increased blood levels of the omega-3 fatty acids (FA) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been inversely associated with risk for sudden cardiac death, but their relationship with acute coronary syndromes (ACS) is unclear. We hypothesized that the EPA+DHA content of blood cell membranes, as a percent of total FAs, is reduced in ACS patients relative to matched controls. We measured the content of EPA+DHA in 768 ACS patients and 768 age-, sex- and race-matched controls. The association with ACS case status of blood cell EPA+DHA [both by a 1 unit change and by category (low, or =8%)] was assessed using multivariate conditional logistic regression models adjusting for matching variables and smoking status, alcohol use, diabetes, body mass index, serum lipids, education, family history of coronary artery disease, personal histories of myocardial infarction and hypertension, and statin, aspirin, and other antiplatelet drug use. The combined groups had a mean age of 61+/-12 years, 66% were male, and 92% were Caucasian. The EPA+DHA content was 20% lower in cases than controls (3.4+/-1.6 vs. 4.25+/-2.0%, pACS event was 0.58 (95% CI 0.42-0.80), in the intermediate EPA+DHA group and was 0.31 (95% CI 0.14-0.67; p for trend ACS case status increased incrementally as the EPA+DHA content decreased suggesting that low EPA+DHA may be associated with increased risk for ACS.

    Optimism is associated with reduced cardiovascular mortality, but its impact on recovery after acute coronary syndrome (ACS) is poorly understood. We hypothesized that greater optimism would lead to more effective physical and emotional adaptation after ACS and would buffer the impact of persistent depressive symptoms on clinical outcomes. This prospective observational clinical study took place in an urban general hospital and involved 369 patients admitted with a documented ACS. Optimism was assessed with a standardized questionnaire. The main outcomes were physical health status, depressive symptoms, smoking, physical activity, and fruit and vegetable consumption measured 12 months after ACS, and composite major adverse cardiac events (cardiovascular death, readmission with reinfarction or unstable angina, and coronary artery bypass graft surgery) assessed over an average of 45.7 months. We found that optimism predicted better physical health status 12 months after ACS independently of baseline physical health, age, sex, ethnicity, social deprivation, and clinical risk factors (B = 0.65, 95% confidence interval [CI] = 0.10-1.20). Greater optimism also predicted reduced risk of depressive symptoms (odds ratio = 0.82, 95% CI = 0.74-0.90), more smoking cessation, and more fruit and vegetable consumption at 12 months. Persistent depressive symptoms 12 months after ACS predicted major adverse cardiac events over subsequent years (odds ratio = 2.56, 95% CI = 1.16-5.67), but only among individuals low in optimism (optimism × depression interaction; p = .014). Optimism predicts better physical and emotional health after ACS. Measuring optimism may help identify individuals at risk. Pessimistic outlooks can be modified, potentially leading to improved recovery after major cardiac events.

    The outcome of patients with ST elevation acute coronary syndrome (ACS) has been increasingly improving in the general population over the past few decades. However, detailed analysis of the results show that the reduction in mortality rates is higher in males compared to their female counterparts. The excess mortality rate observed in women, though sometimes questioned, has been widely reported in the literature. The higher mortality rate observed in women with ST elevation ACS can be explained by the presence of aggravating clinical factors such as older age, a higher percentage of diabetics, and a higher frequency of cardiogenic shock. Other factors pertaining to patient management seem to negatively impact the outcome. These factors include a lower use of reperfusion strategies, longer time to treatment mainly as a result of diagnostic uncertainty with respect to a disease, which is believed to affect principally the male gender. The doubts that female patients themselves and their families have about the nature of their symptoms are also present in the medical environment but cease to exist in the catheterization laboratory. This is illustrated in the first clinical case that we present here. Coronary reperfusion is the cornerstone of the therapeutic management of MI. In this context, bleeding complications associated with the implemented treatments can also result in an increased mortality rate in this more vulnerable population. When all the factors likely to influence the prognosis are taken into account, excess mortality seems to persist in women, especially in younger patients. As described in the second clinical case, a distinct physio-pathological factor, more frequent in women, could account for this higher mortality rate. Indeed, spontaneous coronary dissection and intramural hematoma are not always easy to diagnose and may not be adequately managed by reperfusion treatments. In addition, these coronary reperfusion strategies are probably not adapted

    In the management of non-ST-segment elevation acute coronary syndromes (NSTE-ACS), several studies have shown a reduction in mortality with the use of an invasive strategy in high-risk patients, including diabetic patients. Paradoxically, other studies have shown an under-utilization of this invasive strategy in these patients. The aim of this study is to determine the characteristics of patients managed conservatively and identify determinants of the use of invasive or conservative strategy. Retrospective cohort study conducted in diabetic patients with NSTE-ACS included in the ARIAM-SEMICYUC registry (n=531) in 2010 and 2011. We performed crude and adjusted unconditional logistic regression. We analyzed 531 diabetic patients, 264 (49.7%) of which received invasive strategy. Patients managed conservatively were a subgroup characterized by older age and cardiovascular comorbidity, increased risk of bleeding and the absence of high-risk electrocardiogram (ECG). In diabetic patients with NSTE-ACS, independent predictors associated with conservative strategy were low-risk ECG, initial Killip class>1, high risk of bleeding and pretreatment with clopidogrel. The fear of bleeding complications or advanced coronary lesions could be the cause of the underutilization of an invasive strategy in diabetic patients with NSTE-ACS.

    Serum fibrinogen level (SF) is thought to be one of the risk factors for coronary artery disease (CAD). The purpose of this study was to measure the SFL in patients with acute coronary syndrome (ACS). This study was performed in patients with ACS, admitted in Shahid Beheshti Hospital, Babol, Iran, from February 2005 to June 2006. Two hundred patients with ACS were divided into 4 groups: Group I - ST elevated myocardial infarction (STEMI); Group II - non-ST elevated myocardial infarction (NSTEMI), Group III - unstable angina (U/A) with ST-T change and Group IV: U/A without ST-T change. Each group includes 50 patients. Twenty-four hours after admission, the SFL was measured using chromatography methods. The data were collected and analyzed. The mean SFL per mg/dl in each group are Group I - 377.8+-28, Group II - 417.2+-26.8, Group III - 335.4+-19.8 and Group IV - 305.1+-13.8. The SFL in Group II was significantly higher in the other group (p=0.002). The SFL in Group II was higher than in Group III (p=0.02) and much higher than in Group IV (p=0.000). The SFL in Group III was more than in Group IV (p=0.018). The results show that SFL is an important marker in patients with ACS, with ST-T change. (author)

  15. Optical Coherence Tomography Imaging in Acute Coronary Syndromes

    Full Text Available Optical coherence tomography (OCT is a high-resolution imaging technique that offers microscopic visualization of coronary plaques. The clear and detailed images of OCT generate an intense interest in adopting this technique for both clinical and research purposes. Recent studies have shown that OCT is useful for the assessment of coronary atherosclerotic plaques, in particular the assessment of plaque rupture, erosion, and intracoronary thrombus in patients with acute coronary syndrome. In addition, OCT may enable identifying thin-cap fibroatheroma, the proliferation of vasa vasorum, and the distribution of macrophages surrounding vulnerable plaques. With its ability to view atherosclerotic lesions in vivo with such high resolution, OCT provides cardiologists with the tool they need to better understand the thrombosis-prone vulnerable plaques and acute coronary syndromes. This paper reviews the possibility of OCT for identification of vulnerable plaques in vivo.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    Elevated heart rate (HR) is associated with mortality in a number of heart diseases. We examined the long-term prognostic significance of HR at discharge in a contemporary population of patients with stable angina (SAP), non-ST-segment elevation acute coronary syndromes (NSTE-ACS), and ST-segment elevation myocardial infarction (STEMI) revascularized with percutaneous coronary intervention (PCI). Patients from the BASKET-PROVE trial, an 11-center randomized all-comers trial comparing bare-metal and drug-eluting stenting in large coronary vessels, were included. Discharge HR was determined from a resting ECG. Long-term outcomes (7 days to 2 years) were evaluated for all-cause mortality and cardiovascular death and non-fatal myocardial infarction. A total of 2029 patients with sinus rhythm were included, 722 (35.6%) SAP, 647 (31.9%) NSTE-ACS, and 660 (32.5%) STEMI. Elevated discharge HR was associated significantly with all-cause mortality: when compared to a reference of 90 bpm. For cardiovascular death/myocardial infarction, a discharge HR >90 bpm was associated with a hazard ratio of 6.2 (2.5-15.5, pacute coronary syndromes an elevated discharge HR was independently associated with poor prognosis. Conversely, a HR <60 bpm at discharge was associated with a good long-term prognosis irrespective of indication for PCI. © 2013.

    Ischemic heart disease remains a leading cause of morbidity and mortality in industrialized nations, and contributes substantially to healthcare expenditure worldwide. As the evidence base in acute coronary syndromes (ACS) has expanded dramatically over decades, longitudinal data demonstrate improvements in risk factor modification, organization of healthcare systems, and disease management that have substantially attenuated the adverse prognosis of both ST-segment elevation myocardial infarction (STEMI) and non-STsegment elevation ACS (NSTE-ACS). Nevertheless, discrepancies remain between genders, and women with ACS often sustain worse outcomes than men. In this review, we focus on the gender and sex-specific commonalities and differences in the pathophysiology, clinical presentations, diagnosis, and risk stratification of ACS. We highlight available data on the interactions between gender and efficacy of current pharmacological and interventional treatment for NSTE-ACS and STEMI. We also examine gender differences in the trends of clinical outcomes, and possible mechanisms that account for persistent care gaps where future efforts can be directed.

    Data on temporal trends of heart failure (HF) in acute coronary syndrome (ACS) are scarce. Improved treatment options may have led to lower case-fatality rates (CFRs) during the last years in ACS complicated by HF. Patients of the nationwide Acute Myocardial Infarction in Switzerland (AMIS)-Plus ACS registry were analyzed from 2000 to 2014. Of 36 366 ACS patients, 3376 (9.3%) had acute or chronic HF, 2111 (5.8%) de novo acute HF (AHF), 964 (2.7%) chronic HF (CHF), and 301 (0.8%) acute decompensated CHF (ADCHF). In-hospital CFRs were highest in patients with ADCHF (32.6%) and de novo AHF (29.7%), followed by patients with CHF (12.9%) and without HF (3.2%, P acute HF. Although advances in ACS therapy improved in-hospital CFRs in patients with no HF or CHF, CFRs remained unchanged and high in patients with acute HF and ACS over the last decade. © 2017 Wiley Periodicals, Inc.

    Some evidence indicates the deterioration of the cardiovascular system during space storms. It is plausible that the space weather conditions during and after hospital admission may affect the risk of coronary events in patients with acute coronary syndromes (ACS). We analyzed the data of 1400 ACS patients who were admitted to the Hospital Lithuanian University of Health Sciences, and who survived for more than 4 days. We evaluated the associations between geomagnetic storms (GS), solar proton events (SPE), and solar flares (SF) that occurred 0-3 days before and after hospital admission and the risk of cardiovascular death (CAD), non-fatal ACS, and coronary artery bypass grafting (CABG) during a period of 1 year; the evaluation was based on the multivariate logistic model, controlling for clinical data. After adjustment for clinical variables, GS occurring in conjunction with SF 1 day before admission increased the risk of CAD by over 2.5 times. GS 2 days after SPE occurred 1 day after admission increased the risk of CAD and CABG by over 2.8 times. The risk of CABG increased by over 2 times in patients admitted during the day of GS and 1 day after SPE. The risk of ACS was by over 1.63 times higher for patients admitted 1 day before or after solar flares.

    We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. This intermediate syndrome was treated with oximes, atropine and artificial ventilation. During treatment, his ECG showed fresh changes of ST elevation. High CPK & CPK-MB levels, septal hypokinesia on 2D echo suggested acute coronary syndrome. Coronary angiography was postponed due to his bedridden and obtunded status. The patient finally recovered fully by day 15 and was discharged. Acute coronary syndrome is a rare occurrence in OP poisoning. The present case thus emphasises the need for careful electrocardiographic and enzymatic monitoring of all patients of organophosphorus poisoning to prevent potential cardiac complication which can prove fatal.

    India has the highest burden of acute coronary syndromes worldwide. Apart from certain lipid alterations that have been established to be definite risk factors, low level of adiponectin, high levels of resistin, and IL-6 have been shown to be risk factors for cardiovascular events. Insulin resistance is also a significant predictor of poor outcome in patients admitted with ACS. 69 male patients with ACS and 70 age-matched healthy males were recruited in the study. Insulin, total adiponectin, resistin, and IL-6 levels were assayed in all study subjects. Indices of insulin resistance and novel adipokine indices were calculated using standard formulae. Multiple logistic regression analysis was done to find out the best predictor of ACS. Resistin, IL-6, insulin resistance indices, AR index, and IRAR index were found to be significantly higher, while insulin sensitivity indices and total adiponectin were found to be lower in cases, as compared with controls (p < 0.001). Insulin resistance was found to be higher in the admission sample, when compared to the fasting sample in patients with ACS (p = 0.01). On multivariate logistic regression analysis, HOMA-IR and AR index were found to be significantly associated with ACS. AR index was the best independent predictor of ACS, with the highest odds ratio (AR index: adjusted OR 17.528, p < 0.0001 versus HOMA-IR: adjusted OR 1.146, p = 0.001). The present results implicate that adipokines are significantly associated with pathogenesis of ACS, warranting adequate and early appropriate treatment to reverse this metabolic dysregulation. In our study, AR index was the best predictor of ACS. Hence, the novel AR index might be useful in routine clinical practice for screening persons with increased risk of future development of ACS.

    Acute coronary syndrome (ACS) is an important public health problem around the world. Since there is a considerable seasonal fluctuation in the incidence of ACS, climatic temperature may have an impact on the onset of this disease. The objective of this study was to assess the relationship between the average daily temperature, diurnal temperature range and emergency room (ER) admissions for ACS in an ER in Taichung City, Taiwan. A longitudinal study was conducted which assessed the correlation of the average daily temperature and the diurnal temperature range to ACS admissions to the ER of the city’s largest hospital. Daily ER admissions for ACS and ambient temperature were collected from 1 January 2000 to 31 March 2003. The Poisson regression model was used in the analysis after adjusting for the effects of holiday, season, and air pollutant concentrations. The results showed that there was a negative significant association between the average daily temperature and ER admissions for ACS. ACS admissions to the ER increased 30% to 70% when the average daily temperature was lower than 26.2°C. A positive association between the diurnal temperature range and ACS admissions was also noted. ACS admissions increased 15% when the diurnal temperature range was over 8.3°C. The data indicate that patients suffering from cardiovascular disease must be made aware of the increased risk posed by lower temperatures and larger changes in temperature. Hospitals and ERs should take into account the increased demand of specific facilities during colder weather and wider temperature variations.

    Evidence-practice gaps exist in the continuum of care for patients with acute coronary syndromes (ACS), particularly at hospital discharge. We aimed to describe the methodology and baseline results of the Discharge Management of Acute Coronary Syndromes (DMACS) project, focusing on the prescription of guideline-recommended medications, referral to cardiac rehabilitation and communication between the hospital, patient and their primary healthcare professionals. DMACS employed Drug Use Evaluation methodology involving data collection, evaluation and feedback, and targeted educational interventions. Adult patients with ACS discharged during a 4-month period were eligible to participate. Data were collected (maximum 50 patients) at each site through an inpatient medical record review, a general practitioner (GP) postal/fax survey conducted 14 days post discharge and a patient telephone survey 3 months post discharge. Forty-nine hospitals participated in the audit recruiting 1545 patients. At discharge, 57% of patients were prescribed a combination of antiplatelet agent(s), beta-blocker, statin and angiotensin-converting enzyme inhibitor and/or angiotensin II-antagonist. At 3 months post discharge, 48% of patients reported using the same combination. Some 67% of patients recalled being referred to cardiac rehabilitation; of these, 33% had completed the programme. In total, 83% of patients had a documented ACS management plan at discharge. Of these, 90% included a medication list, 56% a chest pain action plan and 54% risk factor modification advice. Overall, 65% of GPs rated the quality of information received in the discharge summary as 'very good' to 'excellent'. The findings of our baseline audit showed that despite the robust evidence base and availability of national guidelines, the management of patients with ACS can be improved. These findings will inform a multifaceted intervention strategy to improve adherence to guidelines for the discharge management of

    Background: Acute Coronary Syndrome (ACS) is increasing in Yemen in recent years and there are no data available on its short and long-term outcome. We evaluated the clinical pictures, management, in-hospital, and long-term outcomes of the ACS patients in Yemen. Design and Setting: A 9-month prospective, multi-center study conducted in 26 hospitals from 9 governorates. The study included 30-day and 1-year mortality follow-up. Patients and Methods: One thousand seven hundred and sixty one patients with ACS were collected prospectively during the 9-month period. Patients with ST-elevation myocardial infarction (STEMI) and non-ST-elevation acute coronary syndrome (NSTEACS), including non-ST-elevation myocardial infarction and unstable angina were included. Conclusions: ACS patients in Yemen present at a relatively young age with high prevalence of Smoking, khat chewing and hypertension. STEMI patients present late, and their acute management is poor. In-hospital evidence-based medication rates are high, but coronary revascularization procedures were very low. In-hospital mortality was high and long-term mortality rates increased two folds compared with the in-hospital mortality. PMID:24695681

    To determine the prevalence of stress hyperglycaemia in people presenting with acute coronary syndrome (ACS), and the relationships between admission glucose and cardiac damage, cardiovascular mortality and morbidity. In a prospective observational study people presenting with ACS at the Gold Coast Hospital had their admission glucose (AG) level tested to determine stress hyperglycaemia. A range of measurements supplemented this data including troponin levels, category of ACS and major adverse coronary events (MACEs) were obtained through hospital records and patient follow-up post-discharge. One hundred eighty-eight participants were recruited. The prevalence of stress hyperglycaemia in ACS was 44% with 31% having a previous diagnosis of type 2 diabetes and 7.7% had undiagnosed diabetes. The stress hyperglycaemic group had a significantly higher median troponin levels compared to participants with normal blood glucose levels on admission (pglucose group (>15 mmol/L) had troponin levels similar to people presenting with normal blood glucose levels and ACS (p>0.05). Cardiac necrosis as measured by troponin levels is significantly increased in people with ACS and stress hyperglycaemia. This study found that one in four participants presenting with ACS and an admission glucose of >7.0 had no previous diagnosis for diabetes. Consistently ordering HbA1C testing on patients with high AG can enable earlier diagnosis and treatment of diabetes. Copyright © 2015. Published by Elsevier Ireland Ltd.

  10. Inflammation Activation Contributes to Adipokine Imbalance in Patients with Acute Coronary Syndrome.

    Full Text Available Inflammation can be activated as a defensive response by the attack of acute coronary syndrome (ACS for ischemic tissue injury. The aim of the present study was to investigate the impact of ACS-activated inflammation on adipokine imbalance and the effects of statins on the crosstalk between inflammation and adipokine imbalance during ACS. In this study, 586 subjects were categorized into: (1 control group; (2 SA (stable angina group; and (3 ACS group. Circulating levels of hs-CRP, adiponectin and resistin were measured by ELISA. Furthermore, forty C57BL/6 mice were randomized into: sham, AMI, low-statin (atorvastatin, 2 mg/kg/day and high-statin (atorvastatin, 20 mg/kg/day group. After 3 weeks, AMI models were established by surgical coronary artery ligation. Circulating levels and adipose expressions of adiponectin and resistin were assessed in animals. Besides, we investigate the effects of atorvastatin on ox-LDL-induced adipokine imbalance in vitro. As a result, we found that ACS patients had higher hs-CRP and resistin levels and lower adiponectin levels. Our correlation analysis demonstrated hs-CRP concentrations were positively correlated with resistin but negatively with adiponectin levels in humans. Our animal findings indicated higher circulating hs-CRP and resistin levels and lower adiponectin levels in AMI mice. Atorvastatin pre-treatment dose-dependently decreased hs-CRP and resistin levels but increased adiponectin levels in mice. The consistent findings were observed about the adipose expressions of resistin and adiponectin in mice. In study in vitro, ox-LDL increased cellular resistin expressions and otherwise for adiponectin expressions, which dose-dependently reversed by the addition of atorvastatin. Therefore, our study indicates that the ACS attack activates inflammation leading to adipokine imbalance that can be ameliorated by anti-inflammation of atorvastatin.

    The investigators of this study sought to examine whether abnormal physiological parameters are associated with increased risk for acute coronary syndrome (ACS) in patients presenting to the emergency department (ED) with chest pain. We used prospectively collected data on adult patients presenting with suspected ACS in 2 EDs in Australia and New Zealand. Trained research nurses collected physiological data including temperature, respiratory rate, heart rate, and systolic blood pressure (SBP) on presentation to the ED. The primary endpoint was ACS within 30 days of presentation, as adjudicated by cardiologists using standardized guidelines. The prognostic utility of physiological parameters for ACS was examined using risk ratios. Acute coronary syndrome was diagnosed in 384 of the 1951 patients (20%) recruited. Compared with patients whose SBP was between 100 and 140 mm Hg, patients with an SBP of lower than 100 mm Hg or higher than 140 mm Hg were 1.4 times (95% confidence interval, 1.2-1.7) more likely to have ACS. Similarly, compared with patients whose temperature was between 36.5°C and 37.5°C, patients with temperature of lower than 36.5°C or higher than 37.5°C were 1.4 times (95% confidence interval, 1.1-1.6) more likely to have ACS. Heart rate and respiratory rate were not predictors of ACS. Patients with abnormal temperature or SBP were slightly more likely to have ACS, but such risk was of too small a magnitude to be useful in clinical decision making. Other physiological parameters (heart rate and respiratory rate) had no prognostic value. The use of physiological parameters cannot reliably confirm or rule out ACS.

    Ischaemic heart disease is the leading cause of in-hospital mortality in Sri Lanka. Acute Coronary Syndrome Sri Lanka Audit Project (ACSSLAP) is the first national clinical-audit project that evaluated patient characteristics, clinical outcomes and care provided by state-sector hospitals. ACSSLAP prospectively evaluated acute care, in-hospital care and discharge plans provided by all state-sector hospitals managing patients with ACS. Data were collected from 30 consecutive patients from each hospital during 2-4 weeks window. Local and international recommendations were used as audit standards. Data from 87/98 (88.7%) hospitals recruited 2177 patients, with 2116 confirmed as having ACS. Mean age was 61.4±11.8 years (range 20-95) and 58.7% (n=1242) were males. There were 813 (38.4%) patients with unstable angina, 695 (32.8%) with non-ST-elevation myocardial infarction (NSTEMI) and 608 (28.7%) with ST-elevation myocardial infarction (STEMI). Both STEMI (69.9%) and NSTEMI (61.4%) were more in males (Pacute setting and on discharge. In STEMI, 407 (66.9%) were reperfused; 384 (63.2%) were given fibrinolytics and only 23 (3.8%) underwent primary percutaneous coronary intervention (PCI). Only 42.3 % had thrombolysis in coronary interventions planned. In patients with ACS, aspirin, clopidogrel and statin use met audit standards in acute setting and on discharge. Vast majority of patients with STEMI underwent fibrinolyisis than PCI, due to limited resources. Primary PCI, planned coronary interventions and timely thrombolysis need improvement in Sri Lanka. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    In Turner syndrome, cardiovascular complications are the most important causes of early mortality. Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. She was diagnosed with Turner Syndrome in her teenage years due to amenorrhea. Patients with ECG changes and cardiac enzyme elevations were treated with acute coronary syndrome. The young woman with Turner Syndrome have several risk factors for early Coronary Artery Disease development. In such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment.

    Atrial fibrillation (AF) and heart failure (HF) are both common comorbid conditions of elderly patients with acute coronary syndrome (ACS), but published data on their associated clinical and economic outcomes are limited. Our study included patients from the Medicare Current Beneficiary Survey with an incident hospitalization for ACS between 03/01/2002 and 12/31/2006. Applying population weights, we identified 795 incident ACS patients, representing more than 2.5 million Medicare beneficiaries. Of this population, 13.1% had comorbid AF, and 22.9% had HF, which were identified from Medicare claims during the 6 months prior to the first ACS event (index date) Subsequent cardiovascular (CV) hospitalizations and mortality were compared using Kaplan-Meier curves. Cox proportional hazards regressions were used to estimate the relative risk of AF and HF on CV events and mortality. Healthcare costs were summarized for the calendar year in which the incident ACS event occurred. HF was associated with a 41% higher risk of mortality (HR = 1.41; 95% confidence interval [CI] 1.05-1.89). Both AF (HR = 1.46; 95% CI 1.14-1.87) and HF (HR = 1.61; 95% CI 1.26-2.06) were associated with higher risks of subsequent CV events. During the year of the incident ACS event, ACS patients with comorbid AF or HF had approximately $18,000 higher total healthcare costs than those without these comorbidities. Using a nationally representative sample of Medicare beneficiaries, we observed a significantly higher clinical and economic burden of patients hospitalized for ACS with comorbid AF and HF compared with those without these conditions.

    Cardiovascular disease is one of the most common causes of death worldwide, with many individuals having experienced acute coronary syndrome (ACS). How patients with a history of ACS value aspects of their medical treatment have been evaluated rarely. The aim of this study was to determine patient priorities for long-term drug therapy after experiencing ACS. To identify patient-relevant treatment characteristics, a systematic literature review and qualitative patient interviews were conducted. A questionnaire was developed to elicit patient's priorities for different characteristics of ACS treatment using Analytic Hierarchy Process (AHP). To evaluate the patient-relevant outcomes, the eigenvector method was applied. Six-hundred twenty-three patients participated in the computer-assisted personal interviews and were included in the final analysis. Patients showed a clear priority for the attribute "reduction of mortality risk" (weight: 0.402). The second most preferred attribute was the "prevention of a new myocardial infarction" (weight: 0.272), followed by "side effect: dyspnea" (weight: 0.165) and "side effect: bleeding" (weight: 0.117). The "frequency of intake" was the least important attribute (weight: 0.044). In conclusion, this study shows that patients strongly value a reduction of the mortality risk in post-ACS treatment. Formal consideration of patient preferences and priorities can help to inform a patient-centered approach, clinical practice, development of future effective therapies, and health policy for decision makers that best represents the needs and goals of the patient.

    Nucleosomes and cell-free double-stranded DNA (dsDNA) have been suggested as promising biomarkers in cell death-related diseases, such as acute coronary syndrome (ACS). Currently, the impact of obstructive sleep apnea (OSA) in patients with ACS is unclear. Our aim was to evaluate the relationship between OSA, dsDNA, and nucleosomes and to assess their potential implication in the development of ACS. Up to 549 patients were included in the study and divided into four groups (145 ACS; 290 ACS + OSA; 62 OSA; 52 controls). All patients underwent a sleep study, and serum concentrations of dsDNA and nucleosomes were measured. Nucleosome and dsDNA levels were higher in patients with OSA than in controls (nucleosomes: 1.47 ± 0.88 arbitary units [AU] vs. 1.00 ± 0.33 AU; p Sleep Research Society 2017.

    To determine the extent to which levels of membrane eicosapentaenoic (EPA)+docosahexaenoic acids (DHA) (the omega-3 index) were associated with depression in patients with acute coronary syndrome (ACS). Depression is associated with worse cardiovascular (CV) outcomes in patients with ACS. Reduced levels of blood cell membrane omega-3 (n-3) fatty acids (FAs), an emerging risk factor for both CV disease and depression, may help to explain the link between depression and adverse CV outcomes. We measured membrane FA composition in 759 patients with confirmed ACS. The analysis included not only EPA and DHA but also the n-6 FAs linoleic and arachidonic acids (LA and AA). Depressive symptoms were measured with the Patient Health Questionnaire-9 (PHQ). Multivariable linear regression was used to adjust for demographic and clinical characteristics. There was a significant inverse relationship between the n-3 index and depressive symptoms (PHQ) in the fully adjusted model (p = .034). For every 4.54% point rise in the n-3 index, there was a 1-point decline in depressive symptoms. In contrast to the n-3 FAs, membrane levels of the n-6 FAs LA and AA were not different between depressed and nondepressed ACS patients. We found an inverse relationship between the n-3 index and the prevalence of depressive symptoms in patients with ACS. Therefore, this study supports the hypothesis that reduced n-3 FA tissue levels are a common and potentially modifiable link between depression and adverse CV outcomes.

    Medical discharge management of acute coronary syndromes (ACS) remains suboptimal outside randomised trials and constitutes an essential quality benchmark for ACS. We sought to evaluate the rates of key guideline-recommended pharmacological agents after ACS and characteristics associated with optimal treatment at discharge. The Rijnmond Collective Cardiology Research (CCR) registry is an ongoing prospective, observational study in the Netherlands that aims to enrol 4000 patients with ACS. We examined discharge and 1-month follow-up medication use among the first 1000 patients enrolled in the CCR registry. Logistic regression was performed to identify patient and hospital characteristics associated with collective guideline-recommended pharmacotherapy at hospital discharge. At discharge, 94 % of patients received aspirin, 100 % thienopyridines, 80 % angiotensin-converting enzyme inhibitors/angiotensin-II receptor blockers, 87 % β-blockers, 96 % statins, and 65 % the combination of all 5 agents. ST-segment elevation myocardial infarction, hypertension, hypercholesterolaemia, and enrolment in an interventional centre were positive independent predictors of 5-drug combination therapy at discharge. Negative independent predictors were unstable angina and advanced age. Current data from the CCR registry reflect a high quality of care for ACS discharge management in the Rotterdam-Rijnmond region. However, potential still remains for further optimisation.

    Full Text Available Background: Acute Coronary Syndrome (ACS is a shift manifestations pattern of ischemic myocardium. Revascularization either with Primary Percutaneous Coronary Intervention (PCI or pharmacological therapy is an optional treatment for ST Elevation Acute Coronary Syndrome (STEACS patients. The aim of the study was to compare the functional capacity using six-minute walking test on STEACS patients who underwent Primary PCI or pharmacological therapy. Methods: A cross sectional study was conducted from September to October 2012 to 35 STEACS patients who were treated after two years. The samples were obtained from the list of patients at Dr. Hasan Sadikin General Hospital. Inclusion criteria consisted of patients diagnosed as STEACS, cooperative and not experiencing cognitive disturbance. The exclusion criteria were STEACS patients with unstable angina or myocardial infarct in the last month, stable exertional angina, and pregnant women. The patients underwent 6 minutes walking test,VO2max was measured using theCalahin and Cooper formula, then Metabolic Equation Task (METs was calculated. Data were analyzed by unpaired T-test. Results: There were 19 Primary PCI and 16 pharmacological therapy patients. The average of age between the two groups was distributed evenly. Most of the STEACS patients were male, had a college/academic degree and were retired. Patients treated with pharmacological therapy had higher average of VO2 max and METs than patients with Primary PCI. There was no significantly differences of METs between those groups (p>0.05 Conclusions: There were no significantly differences of functional capacity in STEACS patients treated with Primary PCI or Pharmacological therapy.

    Small non-coding microRNAs (miRNAs) are important physiological regulators of post-transcriptional gene expression. miRNAs not only reside in the cytoplasm but are also stably present in several extracellular compartments, including the circulation. For that reason, miRNAs are proposed as diagnostic biomarkers for various diseases. Early diagnosis of acute coronary syndrome (ACS), especially non-ST elevated myocardial infarction and unstable angina pectoris, is essential for optimal treatment outcome, and due to the ongoing need for additional identifiers, miRNAs are of special interest as biomarkers for ACS. This review highlights the nature and cellular release mechanisms of circulating miRNAs and therefore their potential role in the diagnosis of myocardial infarction. We will give an update of clinical studies addressing the role of circulating miRNA expression after myocardial infarction and explore the diagnostic value of this potential biomarker.

    Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p risk of MACEs increased with increasing RDW content (p value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Objective: To evaluate analysis of clinical application on determining serum inflammatory cytokines levels in patients with acute coronary syndrome (ACS). Methods: The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), high-sensitive C-reaction protein (hs-CRP) (with high-sensitive enzyme immunoassay) and tumor necrosis factor-α (TNF-α) (with radioimmunoassay) in serum were determined in 112 patients with ACS, 32 patients with stable angina pectoris (SAP) and 42 normal controls as well as did compared analysis. Results: The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels in 112 patients with ACS were obviously higher than those in 42 controls (P all 0.05), serum hs-CRP level was increased only (P<0.05). The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels in 46 patients with acute myocardial infraction (AMI) were prominently higher than those in 66 patients with unstable angina pectoris (UAP) and in 32 patients with SAP. The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels with advanced degree SAP, UAP and AMI were increased. Conclusion: In the severity of the patients with SAP, UAP, AMI, the determination of serum inflammatory cytokines level were a good and important index, so that it was referential for heart coronary events happened.

    We aimed was to assess the association of acute coronary syndrome (ACS) with selected food groups pertinent to non-Mediterranean prototype in Albania, a transitional post-communist country in Southeast Europe. We conducted a case-control study in Tirana in 2003-2006 including 467 non-fatal consecutive ACS patients (370 men aged 59.1±8.7 years, 97 women aged 63.3±7.1 years; 88% response) and a population-based control group (469 men aged 53.1±10.4 years, 268 women aged 54.0±10.9 years; 69% response). A semi-quantitative food frequency questionnaire including 105 food items was administered to all participants based on which the daily calorie intake for selected food groups (meat products, overall oils and fats, sweets, and junk food) was calculated. General linear model was used to assess the association of food groups with ACS. Mean age-adjusted values of meat products, overall oils and fats, sweets and junk food were all considerably higher in cases than controls in both sexes. Cases had significantly higher mean "non-Mediterranean" diet scores (consisting of junk food, sweets, oils and fats except olive oil) than controls (10.3% vs. 5.9% in men and 15.2% vs. 8.3% in women, Pconsumption of processed foods was associated with considerable excess coronary risk which points to serious health implications for the Albanian adult population.

    To assess the impact of on-admission heart rate (HR) in patients presenting with acute coronary syndrome (ACS). Data were collected retrospectively from the second Gulf Registry of Acute Coronary Events. Patients were divided according to their initial HR into: (I: < 60, II: 60-69, III: 70-79, IV: 80-89 and V: ≥ 90 bpm). Patients' characteristics and hospital and one- and 12-month outcomes were analyzed and compared. Among 7939 consecutive ACS patients, groups I to V represented 7%, 13%, 20%, 23.5%, and 37%, respectively. Mean age was higher in groups I and V. Group V were more likely males, diabetic and hypertensive. ST-elevation myocardial infarction was the main presentation in groups I and V. Reperfusion therapies were less likely given to group V. Beta blockers were more frequently prescribed to group III in comparison to groups with higher HR. Groups I and V were associated with worse hospital outcomes. Multivariate analysis showed initial tachycardia as an independent predictor for heart failure (OR 2.2; 95%CI: 1.39-3.32), while bradycardia was independently associated with higher one-month mortality (OR 2.0; 95%CI: 1.04-3.85) CONCLUSION: The majority of ACS patients present with tachycardia. However, low or high HR is a marker of high risk that needs more attention and management.

    Acute heart failure (HF) associated with an acute coronary syndrome (ACS) predicts adverse outcome. There have been important recent improvements in ACS management. Our aim was to describe the management and outcomes in those with and without HF in a contemporary ACS cohort. Consecutive patients presenting with ACS between 2007 and 2011 were enrolled in the All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS-QI) registry. Outcomes and medication dispensing were obtained using anonymised linkage to national data sets. A summary pharmacotherapy measure of "quadruple therapy" was defined as dispensing of at least one agent from each of the four evidence-based classes - anti-platelet, statin, angiotensin converting enzyme inhibitor/angiotensin receptor blocker and beta blocker. Of 3743 ACS patients 14% had acute HF. Acute heart failure patients were older (69.2±12.6 vs 62.3±12.8 years, pcoronary angiography (66% vs 86%, pAcute heart failure complicating ACS is associated with heightened risk of short-term and long-term mortality. One in three ACS patients with HF did not have coronary angiography and less than half received quadruple therapy a year after presentation. Copyright © 2016. Published by Elsevier B.V.

    AIMS Our study aimed to examine the impact of concomitant use of proton pump inhibitors (PPIs) with clopidogrel on the cardiovascular outcomes of patients with acute coronary syndrome (ACS). Furthermore, we sought to quantify the effects of five individual PPIs when used concomitantly with clopidogrel. METHODS We conducted a retrospective cohort study of patients who were newly hospitalized for ACS between 1 January 2006 and 31 December 2007 retrieved from the Taiwan National Health Insurance Research Database (NHIRD) and who were prescribed clopidogrel (n= 37 099) during the follow-up period. A propensity score technique was used to establish a matched cohort in 1:1 ratio (n= 5173 for each group). The primary clinical outcome was rehospitalization for ACS, while secondary outcomes were rehospitalization for percutaneous transluminal coronary angioplasty (PTCA) with stent, PTCA without stent and revascularization (PTCA or coronary artery bypass graft surgery) after the discharge date for the index ACS event. RESULTS The adjusted hazard ratio of rehospitalization for ACS was 1.052 (95% confidence interval, 0.971–1.139; P= 0.214) in the propensity score matched cohort. Among all PPIs, only omeprazole was found to be statistically significantly associated with an increased risk of rehospitalization for ACS (adjusted hazard ratio, 1.226; 95% confidence interval, 1.066–1.410; P= 0.004). Concomitant use of esomeprazole, pantoprazole, rabeprazole and lansoprazole did not increase the risk. CONCLUSIONS Our study indicated no statistically significant increase in the risk of rehospitalization for ACS due to concurrent use of clopidogrel and PPIs overall. Among individual PPIs, only omeprazole was found to be statistically significantly associated with increased risk of rehospitalization for ACS. PMID:22364155

Secondly, to compare association of angiographic severity of vascular stenosis with CRP in patients with ST segment elevation myocardial infarction (STEMI) and non-STEMI / Unstable angina (UA). Prospective, descriptive study. Khan Research Laboratories (KRL) Hospital, from October 2014 to March 2015. CRP was measured on diagnosis of ACS in 70 patients. Cardiac enzymes were measured 6 hours after the onset of chest pain. Angiographic scoring for degree of stenosis and number of culprit vessels was done. Two groups consisting of patients with STEMI (group 1) and with NSTEMI/UA (group 2) were made. No correlation was found between CRP levels and angiographic stenosis in patients with ACS (r=0.162, p>0.05). No association was found between eosinophil count and severity of stenosis (p=0.88). Rise of cardiac enzymes and degree of coronary stenosis showed a positive correlation (p Rise in cardiac enzymes still grade high in predicting severity of vascular stenosis than eosinophil count or CRP levels.

    Full Text Available Studies from high-income countries have shown that women receive less aggressive diagnostics and treatment than men in acute coronary syndromes (ACS, though their short-term mortality does not appear to differ from men. Data on gender differences in ACS presentation, management, and outcomes are sparse in India.The Detection and Management of Coronary Heart Disease (DEMAT Registry collected data from 1,565 suspected ACS patients (334 women; 1,231 men from ten tertiary care centers throughout India between 2007-2008. We evaluated gender differences in presentation, in-hospital and discharge management, and 30-day death and major adverse cardiovascular event (MACE; death, re-hospitalization, and cardiac arrest rates. Women were less likely to present with STEMI than men (38% vs. 55%, p<0.001. Overall inpatient diagnostics and treatment patterns were similar between men and women after adjustment for potential confounders. Optimal discharge management with aspirin, clopidogrel, beta-blockers, and statin therapy was lower for women than men, (58% vs. 65%, p = 0.03, but these differences were attenuated after adjustment (OR = 0.86 (0.62, 1.19. Neither the outcome of 30-day mortality (OR = 1.40 (0.62, 3.16 nor MACE (OR = 1.00 (0.67, 1.48 differed significantly between men and women after adjustment.ACS in-hospital management, discharge management, and 30-day outcomes did not significantly differ between genders in the DEMAT registry, though consistently higher treatment rates and lower event rates in men compared to women were seen. These findings underscore the importance of further investigation of gender differences in cardiovascular care in India.

    Acute coronary syndrome (ACS) is considered one of the main causes of death worldwide. Contradictory findings concerning the impact of the angiotensin-converting enzyme (ACE) gene on cardiovascular diseases have been reported. Previous conclusions point out that the variability in results depends on ethnicity and genetic polymorphisms to determine the association of rs4340 polymorphisms of the ACE gene and ACE circulating levels in ACS. Genotyping of rs4340 polymorphisms was performed in a total of 600 individuals from Western Mexico divided into two groups: the ACS and the control group (CG). The polymorphisms were identified by polymerase chain reaction. Serum ACE concentration was determined by enzyme-linked immunosorbent assay. D/D carriers had higher ACE levels than I/I carriers (3.6 vs 2.8 ng/mL, P ACE concentration levels; however, the polymorphism was not associated with ACS.

    Although patients ≥80 years old constitute the fastest-growing segment of the population and have a high prevalence of coronary artery disease, few data exist regarding the outcome of octogenarians with acute coronary syndrome (ACS). In a retrospective study based on data of 13,432 ACS patients who were enrolled in the ACS Israel Survey, we first evaluated the clinical outcome of 1,731 ACS patients ≥80 years (13%) compared with 11,701 ACS patients <80 years (87%) hospitalized during 2000 to 2013. Second, we evaluated the clinical outcome of patients ≥80 years hospitalized during the 2000 to 2006 ("early") period (n = 1,037) compared with those of the same age group of patients hospitalized during the 2008 to 2013 ("late") period (n = 694). Implementation of the ACS AHA/ACC/ESC therapeutic guidelines was lower in ACS patients ≥80 years compared with patients <80 years. Multivariate Cox regression analysis demonstrated a worse 1-year survival rate in the ACS patients ≥80 years compared with those <80 years. During the late period, patients ≥80 years were more frequently treated with guideline-recommended therapies compared with patients from the same age group who were hospitalized in the early period. Multivariate Cox regression analysis demonstrated a better 1-year survival rate of patients ≥80 years during the late period compared with the early period (hazard ratio 1.17, 95% confidence interval 1.15 to 1.61; p = 0.01). In addition, adverse outcome rates of ACS patients ≥80 years were significantly higher compared with those of patients <80 years. However, survival rates of ACS patients ≥80 years were improved over the 200 to 2013 period. Copyright © 2017 Elsevier Inc. All rights reserved.

    The aim of this study was to assess the prevalence, clinical features, and in-hospital outcomes of heart failure in patients with acute coronary syndrome (ACS). The Saudi Project for Assessment of Coronary Events recruited patients admitted with ACS from 17 hospitals in Saudi Arabia from 2005 to 2007. The outcomes of ACS patients with congestive heart failure (CHF) compared with those without CHF were analyzed. A total of 4523 patients with ACS were identified, of whom 905 (20%) had CHF. Compared with no CHF, patients with CHF were older (62±13.1 vs. 57±12.9 years; P=0.001), less likely to be men (70 vs. 79%; P=0.001), likely to present with non-ST-segment elevation myocardial infarction (48 vs. 36%; P=0.001), likely to have diabetes (71 vs. 54%; P=0.001), hypertension (64 vs. 54%; P=0.001) and previous history of coronary artery disease (53 vs. 43%; P=0.001), and likely to have significant left ventricular systolic dysfunction (left ventricular ejection fraction coronary intervention (19 vs. 50%; P=0.001). Adjusted in-hospital mortality and cardiogenic shock were higher in the CHF group (odds ratio 4.43, 95% confidence interval 2.52-7.78; and odds ratio 3.51, 95% confidence interval 2.23-5.52), respectively. ACS patients with CHF in the Saudi Project for Assessment of Coronary Events were older, more likely to have more cardiac risk factors, and less likely to be treated with optimum medical treatment on admission. These findings were associated with higher incidence of their in-hospital adverse outcomes. More aggressive treatment is warranted to improve prognosis.

    Prior percutaneous coronary intervention (PCI) is increasingly encountered in acute coronary syndrome (ACS) patients, with uncertain significance. We sought to evaluate the impact of prior PCI in ACS patients. Patients with ACS enrolled in the prospective PROSPECT registry underwent three-vessel intravascular ultrasound and virtual histology evaluation after successful PCI of the culprit lesion(s). We identified patients with prior PCI (>6 months before index ACS) and compared their outcomes to those without prior PCI. Time-to-event for major adverse cardiac events (MACE) was estimated up to three years, and the independent association between prior PCI and MACE was evaluated in a multivariable model. Among 696 patients enrolled, 77 (11.1%) had prior PCI. They were older and more likely to have prior myocardial infarction, chronic kidney disease, and congestive heart failure. At three years, patients with prior PCI had significantly higher rates of cardiac death, rehospitalisation for worsening angina, and MACE (adjusted HR=1.73 [95% CI: 1.09, 2.75], p=0.02), independent of other comorbidities and intravascular ultrasound findings. Prior PCI was noted in over 10% of patients with ACS and was associated with higher mortality and morbidity, independent of other comorbidities. Prior PCI should be considered a high-risk feature when evaluating ACS patients.

    Although fatty acid intake has been associated with risk of coronary disease events, the association between blood omega-6 and trans fatty acids (FAs) at the time of an acute coronary syndrome (ACS) is unknown. The relationship of blood FA composition to ACS was analyzed in 768 incident cases and 768 controls (matched on age, sex, and race). Compared to controls, ACS cases' blood cell membrane content of linoleic acid was 13% lower (P 3 times the odds for being a case (odds ratio [OR] 3.23, 95% confidence interval [CI] 2.63-4.17). The relationship of arachidonic acid to ACS was U shaped; compared to the first quartile of arachidonic acid, the ORs for case status in the second, third, and fourth quartiles were 0.73 (95% CI 0.47-1.13), 0.65 (95% CI 0.41-1.04), and 2.32 (95% CI 1.39-3.90), respectively. The OR for a 1-SD increase in trans oleic acid was 1.24 (95% CI 1.06-1.45), and for trans-trans linoleic acid, 1.1 (95% CI 0.93-1.30). All associations were independent of membrane omega-3 FA content. High blood levels of linoleic acid but low levels of trans oleic acid are inversely associated with ACS. The relationship of arachidonic acid to ACS appears more complex.

    The purpose of this review was to compare quality of care and outcomes following acute coronary syndrome (ACS) in Central and Eastern European Transitional (CEET) countries. This was a review of original ACS articles in CEET countries from PubMed, ISI Web of Science, Medline and Embase databases published in English from November 2003 to February 2014. Seventeen manuscripts fulfilled the search criteria. Of 19 CEET countries studied, there were no published ACS management or outcome data for four countries. In-hospital mortality for patients with acute myocardial infarction (AMI) ranged from 6.3% in the Czech Republic to 15.3% in Latvia. In-hospital mortality for ST-elevation myocardial infarction (STEMI) ranged from 3.0% in Poland to 20.7% in Romania. For STEMI, primary percutaneous coronary intervention (PCI) ranged from 1.0% to over 92.0%, fibrinolytic therapy from 0.0% to 49.6%, and no reperfusion therapy from 7.0% to 63.0%. Many CEET countries do not have published ACS care and outcomes data. Of those that do, there is evidence for substantial geographical variation in early mortality. Wide variation in emergency reperfusion strategies for STEMI suggests that acute cardiac care is likely to be modifiable and if addressed could reduce mortality from ACS in CEET countries. The collection of ACS care and outcomes data across Europe must be prioritised. © The European Society of Cardiology 2014.

    Objective: To determine the correlation of C-reactive protein (CRP) levels with the severity of coronary stenosis on angiography and the association of cardiac enzymes with the degree of stenosis in acute coronary syndrome (ACS) patients. Secondly, to compare association of angiographic severity of vascular stenosis with CRP in patients with ST segment elevation myocardial infarction (STEMI) and non-STEMI / Unstable angina (UA). Study Design: Prospective, descriptive study. Place and Duration of Study: Khan Research Laboratories (KRL) Hospital, from October 2014 to March 2015. Methodology: CRP was measured on diagnosis of ACS in 70 patients. Cardiac enzymes were measured 6 hours after the onset of chest pain. Angiographic scoring for degree of stenosis and number of culprit vessels was done. Two groups consisting of patients with STEMI (group 1) and with NSTEMI/UA (group 2) were made. Results: No correlation was found between CRP levels and angiographic stenosis in patients with ACS (r=0.162, p>0.05). No association was found between eosinophil count and severity of stenosis (p=0.88). Rise of cardiac enzymes and degree of coronary stenosis showed a positive correlation (p <0.001). There was significant difference in the means of coronary artery stenosis scores between the two groups (Gensini score of groups 1 and 2: 35.9 +- 4 and 14 +- 8, respectively) p<0.001, but there was no significant difference in CRP levels. Conclusion: CRP is a marker of inflammation in ACS rather than a risk factor for determining the severity of vascular stenosis. Rise in cardiac enzymes still grade high in predicting severity of vascular stenosis than eosinophil count or CRP levels. (author)

    Previous studies demonstrated women presenting with acute coronary syndrome (ACS) have poor outcomes when compared with men 'the gender gap phenomenon'. The impact of prior coronary artery bypass graft (CABG) on women presenting with ACS is unknown. We hypothesised that the gender gap is altered in ACS patients with prior CABG. The aim of this study was to evaluate patients presenting with ACS according to their gender and history of prior CABG. Retrospective, observational (cohort) study. Data were collected from hospital-based registry of patients hospitalised with ACS in Doha, Qatar, from 1991 through 2010. The data were analysed according to their gender and history of prior CABG. A total of 16 750 consecutive patients with ACS were studied. In total, 693 (4.3%) patients had prior CABG; among them 125 (18%) patients were women. Comparisons of clinical characteristics, inhospital treatment, and outcomes, including inhospital mortality and stroke were made. Women with or without prior CABG were older, less likely to be smokers, but more likely to have diabetes mellitus (DM), hypertension and renal impairment than men (p=0.001). Women were less likely to receive reperfusion and early invasive therapies. When compared with men, women without prior CABG carried higher inhospital mortality (11% vs 4.9%; p=0.001) and stroke rates (0.9% vs 0.3%; p=0.001). Female gender was independent predictor of poor outcome. Among prior CABG patients, despite the fact that women had worse baseline characteristics and were less likely to receive evidence-based therapy, there were no significant differences in mortality or stroke rates between the two groups. Consistent with the world literature, women presenting with ACS and without prior CABG had higher death rates compared with men. Patients with prior CABG had comparable death rates regardless of the gender status.

    Heart failure (HF) is a serious complication of acute coronary syndromes (ACS), and is associated with high in-hospital mortality and poor long-term survival. The aims of this study were to describe the clinical characteristics, management and in-hospital outcomes of coronary syndrome (ACS) patients with HF in the United Arab Emirates. The study was selected from the Gulf Registry of Acute Coronary Events (Gulf RACE), a prospective multi-national, multicenter registry of patients hospitalized with ACS in six Middle East countries. The present analysis was focused on participants admitted to various hospitals in the UAE with a diagnosis of ACS in 2007 and were analyzed in terms of HF (Killip class II/III and IV) on admission. Of 1691 patients (mean age: 52.6 ± 11.7 years; 210 Females, 1481 Males) with ACS, 356 (21%) had an admission diagnosis of HF (Killip class II/III and IV). HF patients were less frequently males (19.2% vs. 34.3%; P < 0.001). HF was more frequently associated with hypertension (64.3% vs. 43.9%; P < 0.001), hyperlipidemia (49.4% vs. 31.8%; P < 0.001) and diabetes mellitus (DM) (51.1% vs. 36.2%; P < 0.001). HF was significantly associated with in-hospital mortality (OR = 11.821; 95% CI: 5.385-25.948; P < 0.001). In multivariate logistic regression, age, hyperlipidemia, heart rate and DM were associated with higher in-hospital HF. HF is observed in about 1 in 5 patients with ACS in the UAE and is associated with a significant increase in in-hospital mortality and other adverse outcomes.

    Periodontitis, a common polymicrobial inflammatory disease in the tooth supporting tissues, is a risk factor for coronary artery disease. One of the proposed underlying mechanisms is the systemic immune response to periodontal infection. We studied how serum antibodies against seven periodontal pathogens and their subgingival levels associate with each other, periodontitis, and coronary artery disease. The Parogene cohort included 505 Finnish patients (mean age 63 y) who underwent coronary angiography, and clinical and radiographic oral examinations. Coronary diagnosis was defined as no significant coronary artery disease (disease (≥50% stenosis, n = 184) and acute coronary syndrome (n = 169). Levels of subgingival Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Porphyromonas endodontalis, Prevotella intermedia, Tannerella forsythia, Campylobacter rectus, and Fusobacterium nucleatum were determined by checkerboard DNA-DNA hybridization. Serum antibody (IgA/IgG) levels were analyzed with enzyme-linked immunosorbent assay (ELISA). Aggregate IgA/IgG burdens were calculated by summing and standardizing the serum antibody levels. Patients with active periodontitis were characterized by higher levels of subgingival bacteria and corresponding IgA/IgG response. Quartiles 2-4 of serum IgA/IgG burden indicated higher risk for acute coronary syndrome (OR 1.84, 95%CI 1.01-3.35 for IgA; OR 1.87, 95%CI 1.01-3.46 for IgG) independently of established cardiovascular risk factors, body mass index, number of teeth, subgingival bacterial levels and periodontal diagnosis. Our findings support the hypothesis that the association between periodontitis and cardiovascular diseases is partly mediated by the immunologic response for periodontal pathogens.

    2017-04-01

    Despite a large volume of evidence supporting the use of dual antiplatelet therapy in patients with acute coronary syndrome, there remains major uncertainty regarding the optimal duration of therapy. Clinical trials have varied markedly in the duration of therapy, both across and within trials. Recent systematic reviews and meta-analyses suggest that shorter durations of dual antiplatelet therapy are superior because the avoidance of atherothrombotic events is counterbalanced by the greater risks of excess major bleeding with apparent increases in all-cause mortality with longer durations. These findings did not show significant heterogeneity according to whether patients had stable or unstable coronary heart disease. Moreover, the potential hazards and benefits may differ when applied to the general broad population of patients encountered in everyday clinical practice who have markedly higher bleeding and atherothrombotic event rates. Clinicians lack definitive information regarding the duration of therapy in patients with acute coronary syndrome and risk scores do not appear to be sufficiently robust to address these concerns. We believe that there is a pressing need to undertake a broad inclusive safety trial of shorter durations of therapy in real world populations of patients with acute coronary syndrome. The clinical evidence would further inform future research into strategies for personalised medicine. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Objective Absence of significant epicardial coronary artery disease (CAD) in patients with acute onset of chest pain and elevation of myocardial necrosis markers is occasionally observed. The aim of this study was to analyse the clinical characteristics and outcome of such patients with advanced age. Methods We retrospectively analysed 4,311 patients with acute onset of chest pain plus necrosis marker elevation. Two hundred and seventy two patients without CAD on angiogram (6.3%) were identified. Out of them, 50 (1.2%) patients ≥ 75 years (Group I) were compared with (1) 222 acute coronary syndrome (ACS) patients without CAD on angiogram < 75 years (Group II), and (2) 610 consecutive patients ≥ 75 years with Non-ST-elevation Myocardial Infarction (NSTEMI) undergoing percutaneous coronary intervention (Group III). Results Group I compared to Group III patients made up for more females (64.0% vs. 49.2%; P < 0.0001), and had more severe anginal symptoms on presentation [Canadian Cardiovascular Society (CCS) class I/II, 26.0% vs. 49.8%; P = 0.02]. Group I patients also had lower troponin levels (0.62 ± 0.8 ng/mL vs. 27 ± 74 ng/mL; P < 0.02), lower leukocyte count (9.4 ± 3.13 × 109 vs. 12 ± 5.1 × 109; P = 0.001) and better preserved left ventricular function (56.7% ± 14.3% vs. 45% ± 11%; P < 0.0001). Event-free survival (cardiac death, myocardial infarction, recurrent angina, and re-hospitalisation) was more frequent in Group I and II patients compared to Group III patients (64.9%, 66.7%, and 41.6%, respectively; P < 0.0001). Conclusions ACS in patients ≥ 75 years without CAD is very infrequent, associated with a (1) similar outcome compared to ACS patients < 75 years without CAD, and (2) significant better outcome compared to NSTEMI patients ≥ 75 years.

    Full Text Available Abstract Background Shorter time to treatment is associated with lower mortality in acute coronary syndromes (ACS. A previous (1994 survey showed substantial delays for acute myocardial infarction (AMI in Ireland. The present study compared current practice with 1994 and surveyed acute coronary syndromes as a more complete contemporary evaluation of critical cardiac care than assessing AMI alone. Methods Following ethics committee approval, all centres (N = 39 admitting acute cardiac patients to intensive/coronary care unit provided information on 1365 episodes. A cross-sectional survey design was employed. Results Since 1994, median hospital arrival to thrombolysis time was reduced by 41% (76 to 45 minutes. Thrombolysis was delivered more often in the emergency department in 2003 (48% vs 2%. Thrombolysis when delivered in the emergency department was achieved faster than thrombolysis delivered in intensive/coronary care (35 mins v 60 mins; z = 5.62, p Conclusions Substantial improvements in time to thrombolysis have occurred since 1994, probably relating to treatment provision in emergency departments. Patient delay pre-hospital is still the principal impediment to effective treatment of ACS. A recent change of definition of AMI may have precluded an exact comparison between 1994 and 2003 data.

    We aimed to study survival and causes of death in patients with ST-elevation acute coronary syndrome (STE-ACS) with and without obstructive coronary artery disease (CAD). We included 4793 consecutive patients with STE-ACS triaged for acute coronary angiography at a large cardiac invasive centre (2009-2014). Of these, 88% had obstructive CAD (stenosis ≥50%), 6% had non-obstructive CAD (stenosis 1-49%), and 5% had normal coronary arteries. Patients without obstructive CAD were younger and more often female with fewer cardiovascular risk factors. Median follow-up time was 2.6 years. Compared with patients with obstructive CAD, the short-term hazard of death (≤30 days) was lower in both patients with non-obstructive CAD [hazard ratio (HR) 0.49, 95% confidence interval (CI) 0.27-0.89, P = 0.018] and normal coronary arteries (HR 0.31, 95% CI 0.11-0.83, P = 0.021). In contrast, the long-term hazard of death (>30 days) was similar in patients with non-obstructive CAD (HR 1.15, 95% CI 0.77-1.72, P = 0.487) and higher in patients with normal coronary arteries (HR 2.44, 95% CI 1.58-3.76, P Causes of death were cardiovascular in 70% of patients with obstructive CAD, 38% with non-obstructive CAD, and 32% with normal coronary arteries. Finally, patients without obstructive CAD had lower survival compared with an age and sex matched general population. STE-ACS patients without obstructive CAD had a long-term risk of death similar to or higher than patients with obstructive CAD. Causes of death were less often cardiovascular. This suggests that STE-ACS patients without obstructive CAD warrant medical attention and close follow-up. Published on behalf of the European Society of Cardiology.

    The aim of this study was to investigate the impact of pre-diabetes (pre-DM) on coronary plaque characteristics and ischemic outcomes in patients with acute coronary syndromes (ACS). Pre-DM (i.e., the early stages of glucometabolic disturbance) is common among patients with ACS, but the extent to which pre-DM influences coronary plaque characteristics and the risk for adverse ischemic events is unclear. In the PROSPECT (Providing Regional Observations to Study Predictors of Events in Coronary Tree) study, patients with ACS underwent quantitative coronary angiography, grayscale intravascular ultrasound, and radiofrequency intravascular ultrasound after successful percutaneous coronary intervention. Patients were divided into 3 groups according to their glucometabolic status, as defined by the American Diabetes Association: normal glucose metabolism (NGM), pre-DM, and diabetes mellitus (DM). These groups were compared with regard to coronary plaque characteristics and the risk for major adverse cardiac events (MACEs) (defined as cardiac death or arrest, myocardial infarction, or rehospitalization for unstable or progressive angina). Among 547 patients, 162 (29.6%) had NGM, 202 (36.9%) had pre-DM, and 183 (33.4%) had DM. There were no significant differences between the groups with regard to intravascular ultrasound findings indicative of vulnerable plaques. Patients with DM had a higher crude rate of MACEs than those with pre-DM or NGM (25.9% vs. 16.3% and 16.1%; p = 0.03 and p = 0.02, respectively). In an adjusted Cox regression model using NGM as the reference group, DM (hazard ratio: 2.20; 95% confidence interval: 1.25 to 3.86; p = 0.006) but not pre-DM (hazard ratio: 1.29; 95% confidence interval: 0.71 to 2.33; p = 0.41) was associated with increased risk for MACEs. Impaired glucose metabolism is common among patients presenting with ACS. DM but not pre-DM is associated with an increased risk for MACEs. Thus, preventing patients from progressing from pre

    Acute coronary syndrome (ACS) is a complex multifactorial and polygenic disorder that is thought to result from the interaction between an individual's genetic makeup and various environmental factors. The aim of this study was to investigate the association of a transforming growth factor-β1 (TGF-β1) polymorphism (-509C>T) with ACS in a Chinese Han population. The TGF-β1 polymorphism was evaluated in 336 patients with ACS and 396 healthy control subjects by polymerase chain reaction-restriction fragment length polymorphism. The genotype distributions of the control and ACS groups were in Hardy-Weinberg equilibrium (X(2) = 3.54 and X(2) = 1.72, respectively, P > 0.05). The frequencies of the CC, CT, and TT genotypes were 22.61, 53.57, and 20.83% in the ACS group, respectively, whereas they were 8.33, 48.74, and 42.17% in controls. There were significant differences between controls and ACS patients in the frequencies of the CC genotype and the C allele. These results suggest that the promoter polymorphism (-509C>T) in TGF-β1 is associated with ACS in this population. The CC genotype and the C allele of TGF-β1 might be a specific risk factor of ACS in the Chinese Han population in Xinjiang.

    Several reports have suggested that nitrates limit acute ischaemic damage by a mechanism similar to preconditioning. This study aims to evaluate the effect of chronic oral nitrates on the clinical presentation and short-term outcomes of patients admitted with acute coronary syndrome (ACS). A retrospective cohort study was conducted in patients with ACS admitted to 62 acute care units from 2010 to 2011. A propensity score-matched samples analysis was performed. We analysed 3171 consecutive patients, of whom 298 (9.4%) were chronically treated with nitrates. Patients previously treated with nitrates had higher comorbidity and disease severity at admission, lower prevalence of ACS with ST elevation, lower troponin elevation, higher prevalence of initial Killip class 2-4 and higher hospital mortality. The propensity score-matched analysis confirmed that previous use of nitrates is independently associated with a lower prevalence of ST-elevation ACS [odds ratio (OR) 0.53, 95% confidence interval (CI) 0.36-0.78; P = 0.0014] and a lower troponin elevation (OR 0.61, 95% CI 0.41-0.92) but not with Killip class on admission (OR 1.18, 95% CI 0.83-1.67, P = 0.3697) or mortality (OR 0.71, 95% CI 0.37-1.38, P = 0.3196). The results support the hypothesis that nitrates have a protective effect on acute ischaemic injury.

    The effect of anxiety and depression on patients with acute coronary syndromes (ACS) warrants investigation, especially during periods of economic crisis. To investigate the relation between anxiety and depression in patients presenting with ACS due to financial crisis and to investigate whether these two entities could predict long-term cardiovascular mortality. Anxiety and depression symptoms were assessed in 350 patients (210 men) presenting with ACS, with 70 (20%) patients showing elevated scores (Hellenic Heart Failure Protocol). Over a mean follow-up of 48 months there were 36 (10%) cardiovascular deaths. Cox proportional hazards models adjusted for other prognostic factors (including age, sex, marital status, creatinine levels, left ventricular ejection fraction, heart failure, atrial fibrillation, previous hospitalisation, and baseline medications) showed that elevated anxiety and depression scores significantly predicted cardiovascular mortality (primary outcome) and all-cause mortality. Elevated anxiety and depression symptoms are related to cardiovascular mortality due probably to financial crisis, even after adjustment for other prognostic indicators in patients with ACS, who received optimised medical treatment.

    Patients with Depression and the acute coronary syndrome (ACS) is rarely detected, although in some studies say that depression can worsen cardiovascularly and increase mortality. From research, Canan F et al found that increasing levels of Mean platelet volume (MPV) as a risk factor for atherosclerosis and MPV was higher in patients with depression compared with patients without depression. In this study used observational methods of measurement of cross-sectional data. Research began in November 2015 - May 2016 against General Hospital inpatients H. Adam Malik Medan. There are 64 patients with a diagnosis of ACS were given quieter Beck Depression Inventory (BDI), then calculated a score of BDI patients and MPV levels were seen when they first entered the hospital before being given treatment. Patients answered quieter on days 3-7 after diagnosis ACS. ACS Patients were divided into 3 groups: acute myocardial infarction with ST elevation, acute myocardial infarction with non-ST elevation and unstable angina pectoris. The level of depression is grouped into not depression, mild depression, moderate depression and severe depression. Statistically significant with p-value<0.05Based on the linear correlation analysis, it was found a positive correlation with r=0.542. And the relationship is statistically significant with p-value 0.000003.

    Objective: To investigate the relationship between plasma TNF-α, IL-1β and CRP levels in aged patients with coronary heart disease and to define the inflammation marker which might recognize and predict acute coronary syndrome. Methods: Radioimmunoassay was used to detect plasma levels of TNF-α, IL-1β and CRP. Results: Plasma levels of TNF-α and IL-β in patients with acute coronary syndrome (ACS) were significantly higher than those in controls (p<0.05; p<0.01) and stable coronary heart disease (SCHD) (p<0.05; p<0.01). Plasma CRP levels in patients with ACS (7.99 +- 11.9 ml/L) were also significantly higher than those in controls (0.99 +- 1.5 mg/L; p<0.01) and patients with SCHD (2.71 +- 5.45 mg/L; p<0.05). There was positive correlation between CRP level and TNF-α (r=0.0545; p<0.01) as well as IL-β (r=0.31, p<0.05). Conclusion: The abnormal expression of cytokines in aged patients with coronary heart disease was correlative to inflammation marker CRP, which suggested that the abnormal expression to the occurrence of acute coronary syndrome and might serve as a marker of unstable atherosclerosis plaque

    The aim was to study the angiographic profile in patients presented as acute coronary syndrome and its relation with risk factors and comparison between genders. This prospective observational study was performed on total 352 patients of acute coronary syndrome were analyzed for various risk factors, angiographic pattern in Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, South India from January 2015 to July 2016. Mean age of presentation was 52.62±11.63 years. Male were 271(77.0%) and female were 81(23.0%). Majority of patients were STEMI (67.6%) followed by UA (24.4%) and NSTEMI (8%). Smoker was 117(33.3%) patients. Hypertensive were 124(35.2%) of patients and 149(42.3%) were diabetics. Family history of CAD was positive in 45(12.8%). On angiographic evaluation left main reference diameter was lower in females (4.02±0.72) than males (4.07±0.82). LAD was most commonly involved followed by RCA and LCX among all three group of acute coronary syndrome. Left main was least involved (8.3%). In STEMI SVD (40.3%) was most common presentation, after that DVD was seen in 22.3%, TVD in 10.5%, non-obstructive coronary was seen in 16% of patients and normal coronary was seen in 11% of patients. In UA 28%, 22.8%, 13.2%, 15.8%, 20.2% was seen in SVD, DVD, TVD, non-obstructive and normal coronary respectively. Long length coronary lesions (>20mm) were seen in majority in all type of acute coronary syndrome. Coronary lesion length was not associated with presentation acute coronary syndrome and genders. Male were most commonly presented as acute coronary syndrome. STEMI was most common presentation. Diabetic was most prevalent risk factor. SVD was most common angiographic pattern and LAD was most common involved arteries.

    Background In this study, we aimed to evaluate the effects of niacin on high sensitivity C reactive protein (hs-CRP) and cholesterol levels in non-ST elevated acute coronary syndrome (NSTE-ACS) patients. Methods In this prospective, open label study, 48 NSTE-ACS were randomized to niacin or control group. Patients continued their optimal medical therapy in the control group. In the niacin group patients were assigned to receive extended-release niacin 500 mg/day. Patients were contacted 1 month later to assess compliance and side effects. Blood samples for hs-CRP were obtained upon admittance to the coronary care unit, in the third day and in the first month of the treatment. Fasting blood samples for cholesterol levels were obtained before and 30 days after the treatment. The primary end point of the study was to evaluate changes in hs-CRP, cholesterol levels, short-term cardiovascular events, and the safety of niacin in NSTE-ACS. Results Baseline demographic, clinical and laboratory characteristics were similar between the two groups. Logarithmic transformation of baseline and 3rd day hs-CRP levels were similar between the groups; but 1 month later, logarithmic transformation of hs-CRP level was significantly lower in the niacin group (0.43 ± 0.39 to 0.83 ± 0.91, p = 0.04). HDL-C level was significantly increased in the niacin group during follow-up. Drug related side effects were seen in 7 patients in the niacin group but no patients discontinued niacin. Conclusions Our findings demonstrate that lower dose extended release niacin can be used safely and decreases hs-CRP and lipid parameters successfully in NSTE-ACS patients. PMID:27122858

    We aimed to study the relationships between left anterior hemiblock (LAHB) and the patient characteristics, management, and clinical outcomes in the setting of acute coronary syndromes (ACS). Admission ECGs of patients enrolled in the Global Registry of Acute Coronary Events (GRACE) ECG substudy, and the Canadian ACS Registry I, were analysed independently at a blinded core laboratory. Multivariable logistic regression analysis was performed to assess the independent associations between LAHB on the admission ECG and in-hospital and 6-month mortality. Of the 11 820 eligible ACS patients, 692 (5.9%) patients had LAHB. The presence of LAHB on admission was associated with older age, male sex, prior myocardial infarction, prior heart failure, worse Killip class, higher creatinine level, and higher GRACE risk score (all pcoronary revascularisation or reperfusion therapy (all p<0.05). The LAHB group had higher in-hospital (6.9% vs 3.9%, p<0.001) and 6-month mortality (12.5% vs 7.7%, p<0.001). However, after adjusting for the known predictors of mortality in the GRACE risk models, LAHB was not independently associated with in-hospital death (OR 1.07, 95% CI 0.76 to 1.52, p=0.70), or death at 6 months (OR 1.00, 95% CI 0.75 to 1.34, p=0.99). Across the broad spectrum of ACS, LAHB was associated with significant comorbidities, high-risk clinical features on presentation, and worse unadjusted outcomes. However, LAHB was not an independent predictor of in-hospital and 6-month mortality and did not carry incremental prognostic value beyond the known prognosticators in the GRACE risk models.

    To assess the relationship between the evolution of T wave inversion (TWI) on the 24-48 h postadmission ECG and the patient characteristics, management and clinical outcomes among those with non-ST elevation acute coronary syndrome (NSTE-ACS). We evaluated admission and 24-48 h follow-up ECGs of 7201 patients with NSTE-ACS from the prospective, multicentre Global Registry of Acute Coronary Events (GRACE) and Canadian ACS Registry I. We performed multivariable analyses to determine the association between new TWI (on follow-up ECG only), resolved TWI (on admission ECG only) and persistent TWI (on both admission and follow-up ECG) and inhospital and cumulative 6-month all-cause mortality. Patients with TWI were older, more likely to have cardiovascular risk factors, higher Killip class and GRACE risk scores. After adjustment for known prognostic factors, compared with patients presenting without TWI, new TWI was associated with significantly lower inhospital mortality (OR=0.60, 95% CI 0.38 to 0.95, p=0.029), whereas resolved (OR=1.06, 95% CI 0.65 to 1.75, p=0.81) and persistent (OR=0.73, 95% CI 0.48 to 1.11, p=0.14) TWI did not predict inhospital mortality. No TWI pattern independently predicted inhospital adverse cardiovascular events or cumulative 6-month mortality. In contrast, ST depression on the admission and follow-up ECG were independent predictors of inhospital and 6-month mortality. Across the spectrum of NSTE-ACS, TWI within 48 h of presentation was associated with high-risk clinical features, but its presence or dynamic change did not provide additional prognostic value beyond other established clinical predictors.

    We sought to characterize presenting electrocardiographic findings in patients with acute coronary syndromes (ACSs) and out-of-hospital cardiac arrest (OHCA). In the Global Registry of Acute Coronary Events and Canadian ACS Registry I, we examined presenting and 24- to 48-hour follow-up ECGs (electrocardiogram) of ACS patients who survived to hospital admission, stratified by presentation with OHCA. We assessed the prevalence of ST-segment deviation and bundle branch blocks (assessed by an independent ECG core laboratory) and their association with in-hospital and 6-month mortality among those with OHCA. Of the 12,040 ACS patients, 215 (1.8%) survived to hospital admission after OHCA. Those with OHCA had higher presenting rates of ST-segment elevation, ST-segment depression, T-wave inversion, precordial Q-waves, left bundle branch block (LBBB), and right bundle branch block (RBBB) than those without. Among patients with OHCA, those with ST-segment elevation had significantly lower in-hospital mortality (20.9% vs 33.0%, p = 0.044) and a trend toward lower 6-month mortality (27% vs 39%, p = 0.060) compared with those without ST-segment elevation. Conversely, among OCHA patients, LBBB was associated with significantly higher in-hospital and 6-month mortality rates (58% vs 22%, p presenting ECG resolved by 24 to 48 hours. In conclusion, compared with ACS patients without cardiac arrest, those with OHCA had higher rates of ST-segment elevation, LBBB, and RBBB on admission. Among OHCA patients, ST-segment elevation was associated with lower in-hospital mortality, whereas LBBB was associated with higher in-hospital and 6-month mortality. Copyright © 2017 Elsevier Inc.

    In spite of robust knowledge about underlying ischemic myocardial damage, acute coronary syndromes (ACS) with culprit-free angiograms raise diagnostic concerns. The present study aimed to evaluate the additional value of cardiac magnetic resonance (CMR) over commonly available non-CMR standard tests, for the differentiation of myocardial injury in patients with ACS and non-obstructed coronary arteries. Patients with ACS, elevated hs-TnT, and a culprit-free angiogram were prospectively enrolled into the study between January 2009 and July 2013. After initial evaluation with standard tests (ECG, echocardiography, hs-TnT) and provisional exclusion of acute myocardial infarction (AMI) in coronary angiogram, patients were referred for CMR with the suspicion of myocarditis or Takotsubo cardiomyopathy (TTC). According to the result of CMR, patients were reclassified as having myocarditis, AMI, TTC, or non-injured myocardium as assessed by late gadolinium enhancement. Out of 5110 patients admitted with ACS, 75 had normal coronary angiograms and entered the study; 69 of them (92%) were suspected for myocarditis and 6 (8%) for TTC. After CMR, 49 patients were finally diagnosed with myocarditis (65%), 3 with TTC (4%), 7 with AMI (9%), and 16 (21%) with non-injured myocardium. The provisional diagnosis was changed or excluded in 23 patients (31%), with a 9% rate of unrecognized AMI. The study results suggest that the evaluation of patients with ACS and culprit-free angiogram should be complemented by a CMR examination, if available, because the initial work-up with non-CMR tests leads to a significant proportion of misdiagnosed AMI.

    The optimal approach to encourage smoking cessation after acute coronary syndrome (ACS) remains unclear. The safety of nicotine replacement therapy (NRT) after ACS is not well established. The aim of the present study was to determine the relationship between NRT use and adverse cardiovascular outcomes after ACS. Using a pre-existing database, 663 smokers with ACS were identified. The patients were separated into the NRT (n = 184) or control (n = 479) groups according to whether NRT was prescribed on hospital discharge. Multivariate logistic regression analysis was used to account for the baseline differences between the 2 groups. Of the 663 patients, 202 had adverse events in the first year after ACS. No significant differences were seen with NRT use for the 1-year combined end point of death, myocardial infarction), repeat revascularization, or rehospitalization for angina, congestive heart failure or arrhythmia (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.61 to 1.30, p = 0.54). There were no differences in the individual 1-year end points of death (odds ratio 0.80, 95% confidence interval 0.33 to 1.91, p = 0.61), myocardial infarction (odds ratio 0.90, 95% confidence interval 0.40 to 2.06, p = 0.80), repeat revascularization (odds ratio 0.77, 95% confidence interval 0.44 to 1.36, p = 0.37), or rehospitalization for angina, congestive heart failure, or arrhythmia (odds ratio 1.01, 95% confidence interval 0.66 to 1.53, p = 0.97). In conclusion, NRT use was not associated with an increased risk of adverse cardiovascular events in the first year after ACS. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Background: Uric acid is an independent risk factor for cardiovascular disease. Hospital admission for ischemic heart disease (IHD is increasing rapidly in our country. Although studies were conducted abroad regarding association of serum uric acid with in-hospital outcomes in patients with acute coronary syndrome (ACS, no data is yet available to show the association in our country. Objective: The objective of this study was to assess the association of serum uric acid level on admission with in-hospital outcomes of the patients with ACS. Materials and Methods: This cross sectional comparative study was done in the Department of Cardiology, Dhaka Medical College Hospital (DMCH from January to December 2012. After proper ethical consideration total 93 ACS patients were enrolled in the study by nonrandom sampling. Serum uric acid of all subjects was measured within 24 hours of admission. Then in-hospital outcomes were observed in all subjects. Results: The frequency of hyperuricemia among ACS patients was 24.7% (22.54% in male and 31.82% in female. Hyperuricemic patients significantly developed heart failure (30.4% vs 11.4%, p=0.032 and conduction defect (13.0% vs 1.4%, p=0.017 than normouricemic subjects. The mean ejection fraction was significantly lower in hyperuricemic patients than patients with normal uric acid level (50.87 ± 10.27% vs 55.94 ± 6.66%. The mean ± SD duration of hospital stay of hyperuricemic group was significantly longer in patients with ACS (8.26 ± 1.18 vs 7.51±1.18 days, p=0.010. Conclusion: The measurement of serum uric acid level, an easily available and inexpensive biochemical tool, might turn out as a valuable risk marker for prediction of in-hospital outcomes in patients with ACS.

    Recent gene-environment interaction studies suggest that diet may influence an individual's genetic predisposition to cardiovascular risk. We evaluated whether omega-3 fatty acid intake may influence the risk for acute coronary syndrome (ACS) conferred by genetic polymorphisms among patients with early onset ACS. Our population consisted of 705 patients of white European descent enrolled in GENESIS-PRAXY, a multicenter cohort study of patients aged 18-55 years and hospitalized with ACS. We used a case-only design to investigate interactions between the omega-3 index (a validated biomarker of omega-3 fatty acid intake) and 30 single nucleotide polymorphisms (SNPs) robustly associated with ACS. We used logistic regression to assess the interaction between each SNP and the omega-3 index. Interaction was also assessed between the omega-3 index and a genetic risk score generated from the 30 SNPs. All models were adjusted for age and sex. An interaction for increased ACS risk was found between carriers of the chromosome 9p21 variant rs4977574 and low omega-3 index (OR 1.57, 95% CI 1.07-2.32, p = 0.02), but this was not significant after correction for multiple testing. Similar results were obtained in the adjusted model (OR 1.55, 95% CI 1.05-2.29, p = 0.03). We did not observe any interaction between the genetic risk score or any of the other SNPs and the omega-3 index. Our results suggest that omega-3 fatty acid intake may modify the genetic risk conferred by chromosome 9p21 variation in the development of early onset ACS and requires independent replication.

    Depression in the context of acute coronary syndrome (ACS) is understood to confer increased morbidity and mortality risk. The pathophysiological mechanisms underlying this association remain poorly understood, although several candidates including inflammation, cardiac autonomic dysregulation, and behavioural factors are viewed as of key importance. No single bio-behavioural explanatory model of ACS-associated depression has emerged, likely due the substantial heterogeneity across both conditions. We studied 344 patients with ACS; 45 fulfilled diagnostic (DSM-IV) criteria for a major depressive episode occurring within 1-month of ACS, and 13 had ongoing major depression that pre-dated ACS and continued through to 1 month post-ACS. We employed two statistical methods (multinomial logistic regression; and latent class analysis) and a range of immunological, autonomic and nutritional markers in an attempt to characterise a biological basis for ACS-associated depression. Regression modelling failed to accurately predict categorical group membership of ACS-associated depression. An alternative data-driven approach produced a three-class solution, with the derived classes differing on measure of C-reactive protein, vitamin D, omega-6:omega-3 ratio, heart rate variability, and age (all p⩽0.004). The majority of participants with ACS-associated and ongoing depression were members of the class characterised by the greatest biological disturbance. Patients with depression differed from those without depression on a range of psychological trait and state variables; additionally reporting poorer sleep quality, higher levels of social isolation, and functional impairment, but had similar biological profiles. Patients with ongoing depression generally had higher scores on these psychological/behavioural measures. Our novel analytic approach identified a combination of biomarkers suggestive of a role for immune, autonomic, and nutritional pathways in the manifestation of

    Cannabis is one of the most widely used illicit substances worldwide, and it has the highest prevalence among drugs used in Egypt. The aims were to evaluate whether the use of cannabis is a risk factor of acute coronary heart disease in low-risk, young males and to compare the cardiac pathological changes between cannabis exposed and non-exposed ischemic patients. This was a cross-sectional study that was performed on 138 male patients, aged ≤ 40 years, with acute myocardial infarction who were admitted to the Cardiac Care Unit at the University Hospital. Urine samples were submitted for toxicological analysis using a homogenous enzyme immunoassay technique to determine the substance of use. The patients were divided into three groups: group 1 (n = 23), cannabis-positive only patients; group 2 (n = 28), patients positive for any other substance of use; and group 3 (n = 34), patients negative for any substance of use. Smoking was prominent, whereas group 1 had no other risk factors. In groups 1 and 2, ST-segment elevation myocardial infarction (STEMI) was dominant, whereas no ST-segment elevation myocardial infarction (NSTEMI) was prominent in group 3. Ischemic resting wall motion abnormalities were presented in 47.8% of group 1 and in only 11.8% of group 3. None of group 1 had normal coronaries, whereas 14.3% of group 3 had normal coronaries. Significant changes in echocardiography and angiography were observed between group 1 and other groups. Cannabis smoking could be a potential risk factor for the development of cardiac ischemia.

    Full Text Available The aim of this study was to evaluate the possibility of incorrect assessment of mortality risk factors in a group of patients affected by acute coronary syndrome, due to the lack of hazard proportionality in the Cox regression model. One hundred and fifty consecutive patients with acute coronary syndrome (ACS and no age limit were enrolled. Univariable and multivariable Cox proportional hazard analyses were performed. The proportional hazard assumptions were verified using Schoenfeld residuals, χ2 test and rank correlation coefficient t between residuals and time. In the total group of 150 patients, 33 (22.0% deaths from any cause were registered in the follow-up time period of 64 months. The non-survivors were significantly older and had increased prevalence of diabetes and erythrocyturia, longer history of coronary artery disease, higher concentrations of serum creatinine, cystatin C, uric acid, glucose, C-reactive protein (CRP, homocysteine and B-type natriuretic peptide (NT-proBNP, and lower concentrations of serum sodium. No significant differences in echocardiography parameters were observed between groups. The following factors were risk of death factors and fulfilled the proportional hazard assumption in the univariable model: smoking, occurrence of diabetes and anaemia, duration of coronary artery disease, and abnormal serum concentrations of uric acid, sodium, homocysteine, cystatin C and NT-proBNP, while in the multivariable model, the risk of death factors were: smoking and elevated concentrations of homocysteine and NT-proBNP. The study has demonstrated that violation of the proportional hazard assumption in the Cox regression model may lead to creating a false model that does not include only time-independent predictive factors.

Methodology: Male patients with acute coronary syndrome were included in this study. Patients having angioplasty (PCI), coronary artery bypass surgery, chronic liver and kidney diseases were excluded. Presence of diabetes, smoking, hypertension, dyslipidemia, physical activity, stress, a family history of coronary artery disease (CAD) and medication was documented. Blood pressure, ECG, cardiac enzymes, fasting blood glucose, lipid profile and echocardiography were done within 24 hours of admission. Body mass index and waist circumference were measured. Data was analysed using SPSS-15. Results: A total of 135 male patients of ACS were studied having mean age of 54.26+-11.60 years. Maximum number of patients aged between 51 to 60 years, (n = 41, 31.9%). STEMI (ST-elevation myocardial infarction) was diagnosed in 96 (71.1%) patients, non-STEMI in 12 (8.9%) while 27 (20%) patients were having unstable angina. Smoking was documented in 60 (44%) patients, hypertension in 50 (37%), diabetes in 34 (25.2%) and a family history of premature CAD was recorded in 24 (17.8%) patients. Fifty one (37.8%) patients were overweight (BMI = 25-29.9) while 22 (16.3%) were obese (BMI greater or equal to 30). Waist circumference > 90 cm was found in 86 (63.6%) subjects. Sixty four (47.4%) patients were active physically. Psychosocial stress was documented in 33 (23.75). Hypertension, diabetes and dyslipidemia were the most frequent combinations, observed in 24 (17.9%) subjects. Conclusion: Dyslipidemia, smoking, hypertension and diabetes were most frequent risk factors. Public awareness to control risk factors can reduce the prevalence of CAD. (author)

    The aim of this study was to develop a method for the identification of global weather parameters and patient characteristics associated with a type of heart attack in which there is a sudden partial blockage of a coronary artery. This type of heart attack does not demonstrate an elevation of the ST segment on an electrocardiogram and is defined as a non-ST elevation acute coronary syndrome (NSTE-ACS). Data from the Global Summary of the Day database was linked with the enrollment and baseline data for a phase III international clinical trial in NSTE-ACS in four 48-h time periods covering the week prior to the clinical event that prompted enrollment in the study. Meteorological events were determined by standardizing the weather data from enrollment dates against an empirical distribution from the month prior. These meteorological events were then linked to the patients' geographic region, demographics and comorbidities to identify potential susceptible populations. After standardization, changes in temperature and humidity demonstrated an association with the enrollment event. Additionally there appeared to be an association with gender, region and a history of stroke. This methodology may provide a useful global insight into assessing the biometeorologic component of diseases from international data.

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

    The effects of loading doses of statins on clinical outcomes in patients with acute coronary syndrome (ACS) and planned invasive management remain uncertain. To determine if periprocedural loading doses of atorvastatin decrease 30-day major adverse cardiovascular events (MACE) in patients with ACS and planned invasive management. Multicenter, double-blind, placebo-controlled, randomized clinical trial conducted at 53 sites in Brazil among 4191 patients with ACS evaluated with coronary angiography to proceed with a percutaneous coronary intervention (PCI) if anatomically feasible. Enrollment occurred between April 18, 2012, and October 6, 2017. Final follow-up for 30-day outcomes was on November 6, 2017. Patients were randomized to receive 2 loading doses of 80 mg of atorvastatin (n = 2087) or matching placebo (n = 2104) before and 24 hours after a planned PCI. All patients received 40 mg of atorvastatin for 30 days starting 24 hours after the second dose of study medication. The primary outcome was MACE, defined as a composite of all-cause mortality, myocardial infarction, stroke, and unplanned coronary revascularization through 30 days. Among the 4191 patients (mean age, 61.8 [SD, 11.5] years; 1085 women [25.9%]) enrolled, 4163 (99.3%) completed 30-day follow-up. A total of 2710 (64.7%) underwent PCI, 333 (8%) underwent coronary artery bypass graft surgery, and 1144 (27.3%) had exclusively medical management. At 30 days, 130 patients in the atorvastatin group (6.2%) and 149 in the placebo group (7.1%) had a MACE (absolute difference, 0.85% [95% CI, -0.70% to 2.41%]; hazard ratio, 0.88; 95% CI, 0.69-1.11; P = .27). No cases of hepatic failure were reported; 3 cases of rhabdomyolysis were reported in the placebo group (0.1%) and 0 in the atorvastatin group. Among patients with ACS and planned invasive management with PCI, periprocedural loading doses of atorvastatin did not reduce the rate of MACE at 30 days. These findings do not support the routine use

    We compared 16-slice computed tomography (CT) with intravascular ultrasound (IVUS) in their ability to identify the culprit lesion, and to assess plaque characterization and vascular remodelling in acute coronary syndrome (ACS). Twenty patients were prospectively studied. Coronary plaque identification and characterization were compared using 16-slice CT and 40-MHz catheter-based IVUS. Minimum lumen area (MLA), cross-sectional vessel area (CVA) and vessel remodelling were determined for each comparable lesion. One hundred and sixty-nine segments were compared and 84 plaques analysed. Sixteen-slice CT detected 95% of culprit lesions (19/20). No feature suggestive of plaque rupture was detected by 16-slice CT. Attenuation measurements within all lesions revealed different values for hypoechoic (38 {+-} 33 HU), hyperechoic (94 {+-} 44 HU), and calcified plaques (561 {+-} 216 HU), (P < 0.001). Agreement between 16-slice CT and IVUS on measuring MLA and CVA was evaluated using Bland-Altman analysis. Pearson and intra-class coefficient (ICC) were 0.81 and 0.70 for MLA, and 0.81 and 0.36 for CVA, for 16-slice CT and IVUS, respectively. Agreement between both techniques for vessel positive remodelling was moderate (kappa = 0.54, P < 0.001). Sixteen-slice CT has shown moderate accuracy in quantifying and characterizing coronary plaques compared with IVUS. Spatial resolution of 16-slice CT remains a major limitation, however, to accurately assess the complex lesions involved in ACS. (orig.)

    To determine the accuracy of 64 MDCT coronary CTA (CCTA) compared to coronary angiography in low risk patients with stable angina and acute coronary syndrome and determine the number of significant coronary artery stenoses ( 50%) in these patients. Materials and methods. Fifty-five patients underwent CCTA using a 32 MDCT unit with z flying focus allowing the acquisition of 64 slices of 0.6 mm thickness as well as coronary angiography (gold standard). Nine patients were excluded due to prior coronary artery bypass surgery (n=4), insufficient breath hold (n=3), calcium scoring>1000 (n=1) and delay between both examinations over 4 months (n=1). Forty-six patients: 27 males and 19 females were included. CCTA results were compared to coronary angiography per segment and artery with threshold detection of stenoses 50%. The degree of correlation between both examinations was performed using a regression analysis with a Pearson correlation coefficient<0.05 considered significant. The overall accuracy of CCTA was 90%; limitations related to the presence of calcifications, motion artifacts or insufficient vessel opacification. The correlation for all analyzed segments was 96.4%. Thirty-eight of 50 significant stenoses seen on coronary angiography were correctly detected on CCTA. Sensitivity, specificity, PPVC and NPV for detection of stenoses 50% were 76%, 98.3%, 80.3% and 97.7% respectively. Evaluation per segment had a NPV of 96.8% (interventricular and diagonal segments) to 100% (main trunk). Our results for specificity and NPV are similar to reports from the literature. This suggests that CCTA in this clinical setting may replace coronary angiography.

    BACKGROUND: Prompt hospital admission is essential when treating acute coronary syndrome. Delay prior to admission is unnecessarily long.

    Alexandre de Matos Soeiro

    Full Text Available Abstract Introduction: A recently published study raised doubts about the need for percutaneous treatment of nonculprit lesions in patients with acute coronary syndromes (ACS. Methods: Retrospective, unicentric, observational study. Objective: To analyze the long-term outcomes in patients undergoing treatment of the culprit artery, comparing those who remained with significant residual lesions in nonculprit arteries (group I versus those without residual lesions in other coronary artery beds (group II. The study included 580 patients (284 in group I and 296 in group II between May 2010 and May 2013. We obtained demographic and clinical data, as well as information regarding the coronary treatment administered to the patients. In the statistical analysis, the primary outcome included combined events (reinfarction/angina, death, heart failure, and need for reintervention. The comparison between groups was performed using the chi-square test and ANOVA. The long-term analysis was conducted with the Kaplan-Meier method, with a mean follow-up of 9.86 months. Results: The mean ages were 63 years in group I and 62 years in group II. On long-term follow-up, there was no significant difference in combined events in groups I and II (31.9% versus 35.6%, respectively, p = 0.76. Conclusion: The strategy of treating the culprit artery alone seems safe. In this study, no long-term differences in combined endpoints were observed between patients who remained with significant lesions compared with those without other obstructions.

    We report a case of acute coronary syndrome in a patient with suspect Marfan syndrome, 25 days after emergent modified Bentall-De Bono intervention for acute type I peripartum aortic dissection. She was admitted to our intensive care unit because of unstable angina, caused by critical blood flow reduction in a large portion of the myocardium, according to the severity of the symptoms and the electrocardiographic alterations. Coronary angiography showed a sub-occlusive stenosis of the left main coronary artery as a result of the dissection extension to the coronary ostium. Because of the high risk related to heart surgery, the patient was successfully treated by unprotected angioplasty and drug-eluting stent positioning. Short- and mid-term outcomes were favourable. Subsequent tests confirmed the diagnosis of Marfan syndrome. After 2 years of follow-up, the patient remains asymptomatic and in good health. To our knowledge, this is the first report of a successful percutaneous intervention of the left main coronary artery in a patient with Marfan syndrome who had already undergone ascending aortic root and valve replacement by the Bentall-De Bono procedure for acute dissection.

    Acute initial management of patients with acute coronary syndrome (ACS) is based on a precise clinical and electrocardiographic diagnosis. Initial risk stratification in the pre-hospital phase is the key step. The last step, adequate patient routing, is decided based on emergency level and reperfusion strategies, considered right from the pre-hospital phase. The management of a patient with an ACS requires close collaboration between emergency physicians and cardiologists, according to simplified protocols for easier access to catheterisation. The next challenges for the pre-hospital management of ACS are based on: - precise knowledge of new antiplatelet and anticoagulant drugs by the emergency physicians, in order to adjust their prescriptions to the patient profile; - developing co-operation between hospitals, according to regional specificities (geographic considerations and distribution of PCI centres) in order to reduce access time to catheterisation rooms; - organising the healthcare network, where the SAMU has an essential role in coordinating the different medical actors; - regular analysis of the evolution of our professional practices, considering, e.g., the guidelines of the "HAS" (French official healthcare guidelines institute);- integrating pre-hospital medicine in health prevention programmes; - improving our understanding of the population's presentations of coronary artery disease, in order to encourage the patients and their families to call the EMS as soon as possible. The challenge of the emergency physician is to adapt the strategies to the patient's needs.

    The study was to access the association between resting heart rate (RHR) and one-year risk of major adverse cardiovascular events (MACE) in acute coronary syndrome (ACS) patients after percutaneous coronary intervention (PCI). Patients with ACS after PCI (n = 808) were prospectively followed-up for MACE. RHR was obtained from electrocardiogram. MACE was defined as a composite of cardiac death, nonfatal recurrent myocardial infarction, ischemic-driven revascularization, and ischemic stroke. The association between RHR and one-year risk of MACE was assessed using Cox proportional hazards regression model. Compared with patients with RHR >76 bpm, the adjusted hazard ratio (AHR) was 0.51 (95% confidence intervals [CI]: 0.23-1.14; P = 0.100) for patients with RHR 76 bpm were at higher risk of MACE during one-year follow-up compared with patients with RHR 61-76 bpm. An elevated RHR ≥ 61 bpm was associated with increased risk of one-year MACE in ACS patients. © 2015 by the Society for Experimental Biology and Medicine.

    Full Text Available Shih-Yin Chen,1 Concetta Crivera,2 Michael Stokes,1 Luke Boulanger,1 Jeffrey Schein2 1United BioSource Corporation, Lexington, MA, USA; 2Janssen Scientific Affairs, LLC, Raritan, NJ, USA Objective: To evaluate the clinical and economic burden of acute coronary syndrome (ACS, a common cardiovascular illness, in the Medicare population. Methods: Data from the Medicare Current Beneficiary Survey were analyzed. Patients with incident hospitalization for ACS without similar events during the 6 months prior were included. Outcomes evaluated included inpatient mortality, 30-day mortality and readmission, subsequent hospitalization events, and total direct health care costs. Sample population weights were applied, accounting for multistage sampling design to obtain nationally representative estimates for the US Medicare population. Results: Between March 1, 2002 and December 31, 2006, we identified 795 incident ACS patients (mean age 76 years; 49% male representing 2,542,211 Medicare beneficiaries. The inpatient mortality rate was 9.71% and the 30-day mortality ranged from 10.96% to 13.93%. The 30-day readmission rate for surviving patients was 18.56% for all causes and 17.90% for cardiovascular disease (CVD-related diagnoses. The incidence of death since admission was 309 cases per 1000 person–years. Among patients discharged alive, the incidence was 197 for death, 847 for CVD-related admission, and 906 for all-cause admission. During the year when the ACS event occurred, mean annual total direct health care costs per person were US$50,458, with more than half attributable to inpatient hospitalization ($27,609. Conclusion: In this national representative Medicare population, we found a substantial clinical and economic burden for ACS. These findings suggest a continuing unmet medical need for more effective management of patients with ACS. The continuous burden underscores the importance of development of new interventions and/or strategies to

    Objective: Neutrophil gelatinase-associated lipocalin (NGAL) is a novel inflammatory marker that is released from neutrophils. In this study, we evaluated the correlation between serum NGAL level and clinical and angiographic risk scores in patients diagnosed with non-ST elevation acute coronary syndrome (NSTE-ACS). Methods: Forty-seven random NSTE-ACS patients and 45 patients with normal coronary arteries (NCA) who underwent coronary angiography were enrolled in the study. GRACE risk score and SYNTAX and Gensini risk scores were used, respectively, for the purpose of clinical risk assessment and angiographic risk scoring. Serum NGAL level was measured via ELISA in peripheral blood samples obtained from the patients at the time of admission. Results: Serum NGAL level was significantly higher in the NSTE-ACS group compared to the control group (112.3±49.6 ng/mL vs. 58.1±24.3 ng/mL, p22) group had statistically significantly higher serum NGAL levels compared to the low SYNTAX (≤22) group (143±29.5 ng/mL vs. 98.7±43.2 ng/mL, p=0.001). Conclusion: NGAL level was positively correlated with lesion complexity and severity of coronary artery disease in patients with NSTE-ACS. Serum NGAL levels on admission are associated with increased burden of atherosclerosis in patients with NSTE-ACS. PMID:25430410

    Background: Classifying acute coronary syndrome (ACS) as ST elevation ACS (STE-ACS) or non-ST elevation ACS (NSTE-ACS) is critical for clinical prognosis and therapeutic decision-making. Assessing the differences in composition and configuration of culprit lesions between STE-ACS and NSTE-ACS can clarify their pathophysiologic differences. Objective: This study focused on evaluating the ability of 64-slice multidetector computed tomography (MDCT) to investigate these differences in culprit lesions in patients with STE-ACS and NSTE-ACS. Methods: Of 161 ACS cases admitted, 120 who fit study criteria underwent MDCT and conventional coronary angiography. The following MDCT data were analyzed: calcium volume, Agatston calcium scores, plaque area, plaque burden, remodeling index, and plaque density. Results: The MDCT angiography had a good correlation with conventional coronary angiography regarding the stenotic severity of culprit lesions (r = 0.86, p < 0.001). The STE-ACS culprit lesions (n = 54) had significantly higher luminal area stenosis (78.6 {+-} 21.2% vs. 66.7 {+-} 23.9%, p = 0.006), larger plaque burden (0.91 {+-} 0.10 vs. 0.84 {+-} 0.12, p = 0.007) and remodeling index (1.28 {+-} 0.34 vs. 1.16 {+-} 0.22, p = 0.021) than those with NSTE-ACS (n = 66). The percentage of expanding remodeling index (remodeling index >1.05) was significantly higher in the STE-ACS group (81.5% vs. 63.6%, p = 0.031). The patients with STE-ACS had significantly lower MDCT density of culprit lesions than patients with NSTE-ACS (25.8 {+-} 13.9 HU vs. 43.5 {+-} 19.1 HU, p < 0.001). Conclusions: Sixty-four-slice MDCT can accurately evaluate the stenotic severity and composition of culprit lesions in selected patients with either STE-ACS or NSTE-ACS. Culprit lesions in NSTE-ACS patients had significantly lower luminal area stenosis, plaque burden, remodeling index and higher MDCT density, which possibly reflect differences in the composition of vulnerable culprit plaques and thrombi.

    Full Text Available Management of anaphylaxis includes adrenaline, a life-saving drug, however appropriate dosing and administration are of crucial importance due to serious side effects. We present a 15-year-old female with anaphylactic reaction manifesting as acute coronary syndrome and pulmonary edema following the administration of adrenaline as an intravenous bolus. Focusing on anaphylaxis, adrenaline and coronary symptoms, this report discussed the interactions between three intertwining entities: Kounis syndrome, Takotsubo cardiomyopathy, and adrenaline-induced coronary vasospasm, and challenges in differential diagnosis. Brugada syndrome (cardiac autonomic dysfunction and clinical manifestation of the patient was also evaluated. Early consideration of adrenaline at the appropriate dose and administration route is essential in anaphylaxis management. Kounis syndrome should be considered in those presenting with allergy symptoms and chest pain and adrenaline should be used carefully due to possible risks of worsening coronary symptoms in patients with Kounis syndrome. This report also highlights a very rare side effect of adrenaline; the drug, which constitutes the cornerstone of anaphylaxis management, has a potential to trigger allergy itself due to metabisulfite-containing preservative.

    Full Text Available OBJECTIVES: Clinical characteristics and trends in the outcome of acute coronary syndrome (ACS in patients with prior coronary artery bypass graft surgery (CABG are unclear. The aim of this study was to evaluate clinical characteristics, in-hospital treatment, and outcomes in patients presented with ACS with or without a history of prior CABG over 2 decades. METHODS: Data were derived from hospital-based study for collected data from 1991 through 2010 of patients hospitalized with ACS in Doha, Qatar. Data were analyzed according to their history of prior CABG. Baseline clinical characteristics, in-hospital treatment, and outcome were compared. RESULTS: A total 16,750 consecutive patients with ACS were studied, of which 693 (4.1% had prior CABG. Patients with prior CABG were older (mean 60.5±11 vs. 53±12 years; P = 0.001, more likely to be females and have more cardiovascular risk factors than the non-CABG group. Prior CABG patients had larger infarct size, were less likely to receive reperfusion therapy, early invasive therapy and more likely to receive evidence-based therapies when compared to non-CABG patients. In-hospital mortality and stroke rates were comparable between the 2 groups. Over 2 decades, there was reduction in the in-hospital mortality rates and stroke rates in both groups (CABG, death; 13.2% to 4%, stroke; 1.9% to 0.0%, non-CABG, death; 10% to 3.2%, stroke 1.0% to 0.1%; all, p = 0.001. CONCLUSION: Significant reduction in-hospital morbidity and mortality among ACS patients with prior CABG over a 20-year period.

    Previously conducted studies revealed that smoking enhanced the efficacy of clopidogrel by increasing formation of the active metabolite (AM) from the prodrug through induction of the cytochrome CYP1A2. The expression of cytochrome enzymes depends on genotype and no data exists in literature conducted in Turkish patients comparing the clopidogrel responsiveness between active smokers and non-active smokers treated with clopidogrel. In this study, our aim was to investigate the clopidogrel responsiveness in clopidogrel-treated Turkish acute coronary syndrome (ACS) patients according to their smoking status. We retrospectively enrolled 258 patients who were hospitalized due to ACS. Clinical variables of the patients, especially smoking status were recorded. Clopidogrel resistance was evaluated by using adenosine diphosphate (ADP) induced platelet aggregometry. Clopidogrel resistance was detected as a change in maximal aggregation ≤20% from baseline. A total of 139 patients were active smokers while 12 were former smokers. 107 patients did not have a history of smoking. Ten of the smokers were hyporesponsive to clopidogrel, whereas 36 of non-smokers were hyporesponsive to clopidogrel (p value >612.5 predicted the clopidogrel resistance with a sensitivity of 60% (OR: 100.65, %95 CI = 19.996-506.615 p paradox" probably exists in Turkish ACS patients.

    As deficiencies in n-3 PUFAs have been linked separately to depression and to cardiovascular disease, they could act as a higher order variable contributing to the established link between depression and cardiovascular disease. We therefore examine the relationship between depression and omega-3 polyunsaturated fatty acids (n-3 PUFA), including total n-3 PUFA, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), in patients with acute coronary syndrome (ACS). Plasma phospholipid levels of n-3 PUFA were measured in 100 patients hospitalized with ACS. Current major depressive episode was assessed by the Composite International Diagnostic Interview (CIDI). Depression severity was assessed by the 18-item Depression in the Medically Ill (DMI-18) measure. Patients clinically diagnosed with current depression had significantly lower mean total n-3 PUFA and DHA levels. Higher DMI-18 depression severity scores were significantly associated with lower DHA levels, with similar but non-significant trends observed for EPA and total n-3 PUFA levels. The finding that low DHA levels were associated with depression variables in ACS patients may explain links demonstrated between cardiovascular health and depression, and may have prophylactic and treatment implications.

    Return to work (RTW) after acute coronary syndrome (ACS) is an important issue for the patient's future. The study aim was to determine whether RTW practice complies with guidelines or is delayed by failure in patient management. We analysed the factors influencing RTW beyond the 90-day period recommended by guidelines. We conducted a survey of 216 self-employed workers admitted to the hospital for ACS using self-report questionnaires and medical examination. Factors influencing RTW, occupational and cardiac features, and recall and source of medical information were investigated. Ninety-three of 216 patients did not return to work by 90 days, despite good cardiac performance in 30 cases (32 %). The mean sick leave duration was 93.3±103.7 days. Advice concerning return to work was completely missing for 44 % of patients. Cardiac performance was independent of sick leave duration, but was correlated with the likelihood of RTW (Pwork-related information. Recall of work-related information was better among patients admitted to a rehabilitation facility (65 %) compared to those who did not receive rehabilitation (Pperformance within 2 months after ACS. Patient management should also include cardiac rehabilitation or therapeutic education toward improving information recall. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Full Text Available Significant left main coronary artery (LMCA stenosis is not rare and reported 3 to 10% of patients undergoing coronary angiography. Unprotected LMCA intervention is a still clinical challenge and surgery is still going to be a traditional management method in many cardiac centers. With a presentation of drug eluting stent (DES, extensive use of IVUS and skilled operators, number of such interventions increased rapidly which lead to change in recommendation in the guidelines regarding LMCA procedures in the stable angina (Class 2a recommendation for ostial and shaft lesion and class 2b recommendation for distal bifurcation lesion. However, there was not clear consensus about the management of unprotected LMCA lesion associated with acute myocardial infarction (MI with a LMCA culprit lesion itself or distinct culprit lesion of other major coronary arteries. Surgery could be preferred as an obligatory management strategy even in the high risk patients. With this review, we aimed to demonstrate treatment strategies of LMCA disease associated with acute coronary syndrome, particularly acute myocardial infarction (MI. In addition, we presented a short case series with LMCA lesion and ST elevated acute MI in which culprit lesion placed either in the left anterior descending artery or circumflex artery. We reviewed the current medical literature and propose simple algorithm for management.

    Full Text Available Drug-eluting stents (DES are increasingly used for treatment of acute coronary syndrome (ACS. However, clinical efficacy and safety of various types of DES is not well established in these subjects. We therefore evaluated clinical utility of second-generation and first-generation DES in patients with ACS by conducting a meta-analysis.A search of Medline, Embase, the Cochrane databases, and Web of Science was made. Randomized controlled trials (RCTs which compared second-generation DES (everolimus-eluting stents [EES] or zotarolimus-eluting stents [ZES] versus first-generation DES (sirolimus-eluting stents [SES] or paclitaxe-eluting stents [PES] in patients with ACS and provided data on clinical efficacy or safety endpoints were included. Pooled estimates were calculated using random-effects model.A total of 2,757 participants with ACS in 6 RCTs were included. Compared with first-generation one, second-generation DES trended to be associated with the decreased incidence of definite or probable stent thrombosis in ACS patients (risk ratio [RR]  = 0.60, 95% confidence intervals [CI] 0.33 to 1.07, p = 0.09. However, the rate of target lesion revascularization (TLR significantly increased in second-generation DES (RR = 2.08, 95%CI 1.25 to 3.47, p = 0.005. There were no significant differences in the incidence of major adverse cardiac events (MACEs, all-cause death, cardiac death, and recurrent myocardial infarction between the two arms (all p>0.10. The second-generation EES showed a tendency towards lower risk of MACEs (p = 0.06 and a beneficial effect on reducing stent thrombosis episodes (p = 0.009, while the second-generation ZES presented an increased occurrence of MACEs (p = 0.02 and TLR (p = 0.003.Second-generation DES, especially EES, appeared to present a lower risk of stent thrombosis, whereas second-generation ZES might increase the need for repeat revascularization in ACS patients.

    Acute coronary syndromes (ACS) are common, but their incidence and outcome might depend greatly on how data are collected. We compared case ascertainment rates for ACS and myocardial infarction (MI) in a single institution using several different strategies. The Hull and East Yorkshire Hospitals serve a population of ∼560 000. Patients admitted with ACS to cardiology or general medical wards were identified prospectively by trained nurses during 2005. Patients with a death or discharge code of MI were also identified by the hospital information department and, independently, from Myocardial Infarction National Audit Project (MINAP) records. The hospital laboratory identified all patients with an elevated serum troponin-T (TnT) by contemporary criteria (>0.03 µg/L in 2005). The prospective survey identified 1731 admissions (1439 patients) with ACS, including 764 admissions (704 patients) with MIs. The hospital information department reported only 552 admissions (544 patients) with MI and only 206 admissions (203 patients) were reported to the MINAP. Using all 3 strategies, 934 admissions (873 patients) for MI were identified, for which TnT was >1 µg/L in 443, 0.04-1.0 µg/L in 435, ≤0.03 µg/L in 19 and not recorded in 37. A further 823 patients had TnT >0.03 µg/L, but did not have ACS ascertained by any survey method. Of the 873 patients with MI, 146 (16.7%) died during admission and 218 (25.0%) by 1 year, but ranging from 9% for patients enrolled in the MINAP to 27% for those identified by the hospital information department. MINAP and hospital statistics grossly underestimated the incidence of MI managed by our hospital. The 1-year mortality was highly dependent on the method of ascertainment.

    Full Text Available Background: Clinical major adverse cardiovascular event (MACE prediction of acute coronary syndrome (ACS is important for a number of applications including physician decision support, quality of care assessment, and efficient healthcare service delivery on ACS patients. Admission records, as typical media to contain clinical information of patients at the early stage of their hospitalizations, provide significant potential to be explored for MACE prediction in a proactive manner. Methods: We propose a hybrid approach for MACE prediction by utilizing a large volume of admission records. Firstly, both a rule-based medical language processing method and a machine learning method (i.e., Conditional Random Fields (CRFs are developed to extract essential patient features from unstructured admission records. After that, state-of-the-art supervised machine learning algorithms are applied to construct MACE prediction models from data. Results: We comparatively evaluate the performance of the proposed approach on a real clinical dataset consisting of 2930 ACS patient samples collected from a Chinese hospital. Our best model achieved 72% AUC in MACE prediction. In comparison of the performance between our models and two well-known ACS risk score tools, i.e., GRACE and TIMI, our learned models obtain better performances with a significant margin. Conclusions: Experimental results reveal that our approach can obtain competitive performance in MACE prediction. The comparison of classifiers indicates the proposed approach has a competitive generality with datasets extracted by different feature extraction methods. Furthermore, our MACE prediction model obtained a significant improvement by comparison with both GRACE and TIMI. It indicates that using admission records can effectively provide MACE prediction service for ACS patients at the early stage of their hospitalizations.

    The aim of our study was to evaluate the immediate results and long-term intake of anti-GP IIb / IIIa inhibitors for patients with acute coronary syndrome treated with coronary angioplasty. The use of anti-GP IIb / IIIa is a valid therapeutic option in patients with acute coronary syndrome with signs of severity and for patients undergoing complex angioplasty. Adverse effects of anti-GP IIb / IIIa can be seen to encourage vigilance and careful monitoring during the administration of these molecules and perfect knowledge of their pharmacological properties for appropriate use.

    We evaluated kinetic changes of high-sensitivity cardiac troponin T (hs-cTnT) in patients with acute coronary syndrome (ACS) and patients with hs-cTnT increases not due to ACS to rule in or rule out non-ST-segment elevation myocardial infarction (STEMI). hs-cTnT was measured serially in consecutive patients presenting to the emergency department. Patients with ACS who had at least 2 hs-cTnT measurements within 6 h and non-ACS patients with hs-cTnT concentrations above the 99th percentile value (14 ng/L) were enrolled to compare absolute and relative kinetic changes of hs-cTnT. For discrimination of non-STEMI (n=165) in the entire study population (n=784), the absolute δ change with the ROC-optimized value of 9.2 ng/L yielded an area under the curve of 0.898 and was superior to all relative δ changes (Prise or fall of at least 9.2 ng/L in the entire study population and 6.9 ng/L in selected ACS patients seems adequate to rule-out non-STEMI. However, δ-values are useful to rule-in non-STEMI only in a specific ACS population.

    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. Copyright © 2017 Elsevier B.V.

    Positive psychological constructs, such as optimism, are associated with beneficial health outcomes. However, no study has separately examined the effects of multiple positive psychological constructs on behavioral, biological, and clinical outcomes after an acute coronary syndrome (ACS). Accordingly, we aimed to investigate associations of baseline optimism and gratitude with subsequent physical activity, prognostic biomarkers, and cardiac rehospitalizations in post-ACS patients. Participants were enrolled during admission for ACS and underwent assessments at baseline (2 weeks post-ACS) and follow-up (6 months later). Associations between baseline positive psychological constructs and subsequent physical activity/biomarkers were analyzed using multivariable linear regression. Associations between baseline positive constructs and 6-month rehospitalizations were assessed via multivariable Cox regression. Overall, 164 participants enrolled and completed the baseline 2-week assessments. Baseline optimism was significantly associated with greater physical activity at 6 months (n=153; β=102.5; 95% confidence interval, 13.6-191.5; P=0.024), controlling for baseline activity and sociodemographic, medical, and negative psychological covariates. Baseline optimism was also associated with lower rates of cardiac readmissions at 6 months (n=164), controlling for age, sex, and medical comorbidity (hazard ratio, 0.92; 95% confidence interval, [0.86-0.98]; P=0.006). There were no significant relationships between optimism and biomarkers. Gratitude was minimally associated with post-ACS outcomes. Post-ACS optimism, but not gratitude, was prospectively and independently associated with superior physical activity and fewer cardiac readmissions. Whether interventions that target optimism can successfully increase optimism or improve cardiovascular outcomes in post-ACS patients is not yet known, but can be tested in future studies.

    Full Text Available Abstract Background: The GRACE Score was derived and validated from a cohort in which octogenarians and nonagenarians were poorly represented. Objective: To test the accuracy of the GRACE score in predicting in-hospital mortality of very elderly individuals with acute coronary syndromes (ACS. Methods: Prospective observational study conducted in the intensive coronary care unit of a tertiary center from September 2011 to August 2016. Patients consecutively admitted due to ACS were selected, and the very elderly group was defined by age ≥ 80 years. The GRACE Score was based on admission data and its accuracy was tested regarding prediction of in-hospital death. Statistical significance was defined by p value < 0,05. Results: A total of 994 individuals was studied, 57% male, 77% with non-ST elevation myocardial infarction and 173 (17% very elderly patients. The mean age of the sample was 65 ± 13 years, and the mean age of very elderly patients subgroup was 85 ± 3.7 years. The C-statistics of the GRACE Score in very elderly patients was 0.86 (95% CI = 0.78 - 0.93, with no difference when compared to the value for younger individuals 0.83 (95% CI = 0.75 - 0.91, with p = 0.69. The calibration of the score in very elderly patients was described by χ2 test of Hosmer-Lemeshow = 2.2 (p = 0.98, while the remaining patients presented χ2 = 9.0 (p = 0.35. Logistic regression analysis for death prediction did not show interaction between GRACE Score and variable of very elderly patients (p = 0.25. Conclusion: The GRACE Score in very elderly patients is accurate in predicting in-hospital ACS mortality, similarly to younger patients.

    Specialized cardiology services have contributed to reduced mortality in acute coronary syndromes (ACS).  We sought to evaluate the outcomes of ACS patients admitted to non-cardiology services in Southern Alberta. Retrospective chart review performed on all troponin-positive patients in the Calgary Health Region identified those diagnosed with ACS by their attending team. Patients admitted to non-cardiology and cardiology services were compared, using linked data from the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry and the Strategic Clinical Network for Cardiovascular Health and Stroke. From January 1, 2007 to December 31, 2008, 2105 ACS patients were identified, with 1636 (77.7%) admitted to cardiology and 469 (22.3%) to non-cardiology services. Patients admitted to non-cardiology services were older, had more comorbidities, and rarely received cardiology consultation (5.1%). Cardiac catheterization was underutilized (5.1% vs 86.4% in cardiology patients (p cardiology vs. cardiology services (49.1% vs. 11.0% respectively at 4-years, p cardiology services. These patients had worse outcomes, despite adjustment for baseline risk factor differences. Although many patients were appropriately admitted to non-cardiology services, the low use of investigations and secondary prevention medications may contribute to poorer patient outcome. Further research is required to identify process of care strategies to improve outcomes and lessen the burden of illness for patients and the health care system.

  11. When is the Best Time for the Second Antiplatelet Agent in Non-St Elevation Acute Coronary Syndrome?

    2016-03-01

    Full Text Available Abstract Dual antiplatelet therapy is a well-established treatment in patients with non-ST elevation acute coronary syndrome (NSTE-ACS, with class I of recommendation (level of evidence A in current national and international guidelines. Nonetheless, these guidelines are not precise or consensual regarding the best time to start the second antiplatelet agent. The evidences are conflicting, and after more than a decade using clopidogrel in this scenario, benefits from the routine pretreatment, i.e. without knowing the coronary anatomy, with dual antiplatelet therapy remain uncertain. The recommendation for the upfront treatment with clopidogrel in NSTE-ACS is based on the reduction of non-fatal events in studies that used the conservative strategy with eventual invasive stratification, after many days of the acute event. This approach is different from the current management of these patients, considering the established benefits from the early invasive strategy, especially in moderate to high-risk patients. The only randomized study to date that specifically tested the pretreatment in NSTE-ACS in the context of early invasive strategy, used prasugrel, and it did not show any benefit in reducing ischemic events with pretreatment. On the contrary, its administration increased the risk of bleeding events. This study has brought the pretreatment again into discussion, and led to changes in recent guidelines of the American and European cardiology societies. In this paper, the authors review the main evidence of the pretreatment with dual antiplatelet therapy in NSTE-ACS.

    Guidelines are designed to encompass the needs of the majority of patients with a particular condition. The American Heart Association (AHA) in conjunction with the American College of Cardiology (ACC) and the American College of Emergency Physicians (ACEP) developed risk stratification guidelines to aid physicians with accurate and efficient diagnosis and management of patients with acute coronary syndrome (ACS). While useful in a primary care setting, in the unique environment of an emergency department (ED), the feasibility of incorporating guidelines into clinical workflow remains in question. We aim to compare emergency physicians' (EP) clinical risk stratification ability to AHA/ACC/ACEP guidelines for ACS, and assessed each for accuracy in predicting ACS. We conducted a prospective observational cohort study in an urban teaching hospital ED. All patients presenting to the ED with chest pain who were evaluated for ACS had two risk stratification scores assigned: one by the treating physician based on clinical evaluation and the other by the AHA/ACC/ACEP guideline aforementioned. The patient's ACS risk stratification classified by the EP was compared to AHA/ACC/ACEP guidelines. Patients were contacted at 30 days following the index ED visit to determine all cause mortality, unscheduled hospital/ED revisits, and objective cardiac testing performed. We enrolled 641 patients presenting for evaluation by 21 different EPs. There was a difference between the physician's clinical assessment used in the ED, and the AHA/ACC/ACEP task force guidelines. EPs were more likely to assess patients as low risk (40%), while AHA/ACC/ACEP guidelines were more likely to classify patients as intermediate (45%) or high (45%) risk. Of the 119 (19%) patients deemed high risk by EP evaluation, 38 (32%) were diagnosed with ACS. AHA/ACC/ACEP guidelines classified only 57 (9%) patients low risk with 56 (98%) of those patients diagnosed with no ACS. In the ED, physicians are more efficient

    We aimed to assess the prevalence and management of clinical familial hypercholesterolaemia (FH) among patients with acute coronary syndrome (ACS). We studied 4778 patients with ACS from a multi-centre cohort study in Switzerland. Based on personal and familial history of premature cardiovascular disease and LDL-cholesterol levels, two validated algorithms for diagnosis of clinical FH were used: the Dutch Lipid Clinic Network algorithm to assess possible (score 3-5 points) or probable/definite FH (>5 points), and the Simon Broome Register algorithm to assess possible FH. At the time of hospitalization for ACS, 1.6% had probable/definite FH [95% confidence interval (CI) 1.3-2.0%, n = 78] and 17.8% possible FH (95% CI 16.8-18.9%, n = 852), respectively, according to the Dutch Lipid Clinic algorithm. The Simon Broome algorithm identified 5.4% (95% CI 4.8-6.1%, n = 259) patients with possible FH. Among 1451 young patients with premature ACS, the Dutch Lipid Clinic algorithm identified 70 (4.8%, 95% CI 3.8-6.1%) patients with probable/definite FH, and 684 (47.1%, 95% CI 44.6-49.7%) patients had possible FH. Excluding patients with secondary causes of dyslipidaemia such as alcohol consumption, acute renal failure, or hyperglycaemia did not change prevalence. One year after ACS, among 69 survivors with probable/definite FH and available follow-up information, 64.7% were using high-dose statins, 69.0% had decreased LDL-cholesterol from at least 50, and 4.6% had LDL-cholesterol ≤1.8 mmol/L. A phenotypic diagnosis of possible FH is common in patients hospitalized with ACS, particularly among those with premature ACS. Optimizing long-term lipid treatment of patients with FH after ACS is required. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2015.

    Full Text Available Abstract Background Previous studies suggested that genetic polymorphisms in the epidermal growth factor receptor (EGFR gene had been implicated in the susceptibility to some tumors and inflammatory diseases. EGFR has been recently implicated in vascular pathophysiological processes associated with excessive remodeling and atherosclerosis. Acute coronary syndrome (ACS is a clinical manifestation of preceding atherosclerosis. Our purpose was to investigate the association of the EGFR polymorphism with the risk of ACS. In this context, we analyzed the HER-1 R497K and EGFR intron 1 (CAn repeat polymorphisms in 191 patients with ACS and 210 age- and sex-matched controls in a Chinese population, using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP strategy and direct sequencing. Results There were significant differences in the genotype and allele distribution of R497K polymorphism of the EGFR gene between cases and controls. The Lys allele had a significantly increased risk of ACS compared with the Arg allele (adjusted OR = 1.49, 95% CI: 1.12–1.98, adjusted P = 0.006. However, no significant relationship between the number of (CAn repeats of EGFR intron 1 (both alleles P = 0.911. Considering these two polymorphisms together, there was no statistically significant difference between the two groups. Conclusion R497K polymorphism of the EGFR gene is significantly associated with the risk of ACS. Our data suggests that R497K polymorphism may be used as a genetic susceptibility marker of the ACS.

    2015-04-01

    Full Text Available Background: Inflammation has been proposed as a contributor to different stages in the pathogenesis of Coronary Heart Disease (CHD. High sensitive C-Reactive Protein (hs-CRP, an acute-phase plasma protein synthesized by the liver, is the most extensively studied systemic marker of inflammation. Elevated hsCRP concentrations early in Acute Coronary Syndrome (ACS, prior to the tissue necrosis, may be a surrogate marker for cardiovascular co-morbidities. The cardiac marker enzymes Creatine Kinase myocardial bound (CK-MB, Aspartate Aminotransferase (AST and lactate dehydrogenase (LDH have been known to be increased in coronary artery diseases. Objective: The aim of the study was to measure hs-CRP levels and other cardiac marker enzymes in ACS patients and to compare the levels of hs-CRP with other cardiac marker enzymes between ST Elevation Myocardial Infarction (STEMI and Non-ST Elevation Myocardial Infarction (NSTEMI patients. Material and Methods: The study group consisted of 207 consecutive patients admitted to Sri Siddhartha Medical College Hospital within the first 6 hours from the onset of chest pain. Patients were diagnosed as Unstable Angina (UA, (n=84; STEMI (n=63 and NSTEMI (n=60. ACS patients were compared with 211 healthy age and sex matched controls. Hs-CRP, CK-MB, AST and LDH levels were measured by standard methods in both groups at baseline and forcases at 36-48 hours i.e. Peak levels. Results: ACS patients had significantly (p<0.05 higher levels of hs-CRP, CKMB, AST and LDH in comparison to controls at baseline. Hs-CRP, CK-MB, AST and LDH levels were significantly higher in STEMI patients compared to NSTEMI patients (p<0.05 at baseline. There was a significant difference regarding peak hs-CRP levels between the two groups, as STEMI patients had significantly higher peak hs-CRP levels compared to NSTEMI patients (p<0.05. Conclusion: STEMI patients have significantly higher peak hsCRP levels compared to NSTEMI patients. These data

    Full Text Available Abstract Background Genome-wide association studies (GWAS have identified new candidate genes for the occurrence of acute coronary syndrome (ACS, but possible effects of such genes on survival following ACS have yet to be investigated. Methods We examined 95 polymorphisms in 69 distinct gene regions identified in a GWAS for premature myocardial infarction for their association with post-ACS mortality among 811 whites recruited from university-affiliated hospitals in Kansas City, Missouri. We then sought replication of a positive genetic association in a large, racially diverse cohort of myocardial infarction patients (N = 2284 using Kaplan-Meier survival analyses and Cox regression to adjust for relevant covariates. Finally, we investigated the apparent association further in 6086 additional coronary artery disease patients. Results After Cox adjustment for other ACS risk factors, of 95 SNPs tested in 811 whites only the association with the rs6922269 in MTHFD1L was statistically significant, with a 2.6-fold mortality hazard (P = 0.007. The recessive A/A genotype was of borderline significance in an age- and race-adjusted analysis of the entire combined cohort (N = 3095; P = 0.052, but this finding was not confirmed in independent cohorts (N = 6086. Conclusions We found no support for the hypothesis that the GWAS-identified variants in this study substantially alter the probability of post-ACS survival. Large-scale, collaborative, genome-wide studies may be required in order to detect genetic variants that are robustly associated with survival in patients with coronary artery disease.

    Full Text Available A 56-year-old woman with no medical history presented to the emergency department complaining of oppressive chest pain of three hours of duration triggered by walking. An electrocardiogram (ECG performed at hospital admission showed ST-segment depression and T-wave inversion in left precordial and inferior leads. Serum troponin I levels were above the normal values. Non ST-segment elevation acute coronary syndrome (NSTEACS was diagnosed and an invasive approach with a percutaneous coronary intervention was performed. No obstructive coronary lesions were observed. However a tortuous coronary fistula emerging from the left-anterior descending coronary artery to the pulmonary artery was observed. Coronary arterio-venous fistulas are present in 0.002% of the general population and in 0.25% of patients undergoing cardiac catheterization for any cause. Most of them are asymptomatic. Ischemic symptoms may develop but are infrequent in patients with no atherosclerotic disease.

    The purpose of the study was to compare the EASI system with the standard 12-lead surface electrocardiogram (ECG) for the accuracy in detecting the main electrocardiographic parameters (J point, PR, QT, and QRS) commonly monitored in patients with acute coronary syndromes or heart failure. In this observational comparative study, 253 patients who were consecutively admitted to the coronary care unit with acute coronary syndrome or heart failure were evaluated. In all patients, two complete 12-lead ECGs were acquired simultaneously. A total of 6,072 electrocardiographic leads were compared (3,036 standard and 3,036 EASI). No significant differences were found between the investigate parameters of the two measurement methods, either in patients with acute coronary syndrome or in those with heart failure. This study confirmed the accuracy of the EASI system in monitoring the main ECG parameters in patients admitted to the coronary care unit with acute coronary syndrome or heart failure.

    Full Text Available Global Registry of Acute Coronary Events (GRACE risk score and red blood cell distribution width (RDW content can both independently predict major adverse cardiac events (MACEs in patients with acute coronary syndrome (ACS. We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58% patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40. GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p < 0.001; 1.699; 1.294-2.232; p < 0.001; respectively. Furthermore, Kaplan-Meier analysis demonstrated that the risk of MACEs increased with increasing RDW content (p < 0.001. For GRACE score alone, the area under the receiver operating characteristic (ROC curve for MACEs was 0.749 (95% CI: 0.707-0.787. The area under the ROC curve for MACEs increased to 0.805 (0.766-0.839, p = 0.034 after adding RDW content. The incremental predictive value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p < 0.001 and integrated discrimination improvement (IDI = 0.023, p = 0.002. Combining the predictive value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Subvalvular aneurysms are the least common type of left ventricular (LV) aneurysms and can be fatal. Subaortic LV aneurysms are much rarer than submitral LV aneurysms and mostly reported in infancy. They can be congenital or acquired secondary to infections, cardiac surgery or trauma. Here, we report a unique presentation of a large, idiopathic subaortic aneurysm in an adult masquerading as an acute coronary syndrome. Diagnosis was made with the help of a CT aortography. Aneurysm was surgically resected with good results. This case highlights the clinical presentation and management of subaortic aneurysms, an important differential for congenital aortic malformations. 2016 BMJ Publishing Group Ltd.

    Objective:Environmental stresses, especially extreme cold and hot weathers, have tendency to have more admissions for acute coronary syndromes. Due to scarcity of local data, we studied the variation in patient admission rates with acute coronary syndrome according to different seasons. Study Design: Descriptive study. Place and Duration of Study: Coronary Care Unit, Civil Hospital and Pakistan Steel Hospital, Karachi, from January 2011 to December 2011. Methodology: The study group comprised consecutive patients with acute coronary syndrome (unstable angina, Non ST-Elevation Myocardial Infarction (NSTEMI), ST-Elevation Myocardial Infarction (STEMI) admitted to the coronary care unit. Patients with stable angina and valvular heart disease were excluded. Data was analyzed for admission according to different seasons, (winter, spring, summer and autumn). Results: The mean age of the 428 cases was 48.5 ± 10.4 years (range 27 to 73 years). Among the study group, 261 (61%) and 167 (39%) cases were male and female respectively. ST-elevation myocardial infarction, non ST-elevation myocardial infarction and unstable angina were present in 206 (48%), 128 (30%) and 94 (22%) respectively. Among the 428 patients, 184 (43%) cases had hypertension, 133 (31%) cases were smokers, 103 (24%) cases had dyslipidemia and diabetes mellitus and 08 (2%) cases had history of premature coronary artery disease. The number of patients admissions with acute coronary syndrome tended to change with sudden change in season. It increased in Winter 158 (36.9%) and Summer 130 (30.3%) in comparison to Spring 80 (18.69%) and Autumn 60 (14.02%) season. Conclusion: It was found variation in admission rates of acute coronary syndrome patients according to different seasons. The number of admissions not only increased in the cold season (winter) but also in hot season (summer) with sudden changes in temperature. (author)

    The optimal time-point of the initiation of P2Y12 antagonist therapy in patients with non-ST elevation acute coronary syndromes (NTSE-ACS) is still a matter of debate. European guidelines recommend P2Y12 as soon as possible after first medical contact. However, the only trial which compared the two...... strategies did not demonstrate any benefit of pre-treatment with prasugrel before angiography compared to starting therapy after angiography and just prior to percutaneous coronary intervention (PCI). This paper summarizes the results of pharmacodynamic and previous studies, and gives recommendations...

    Full Text Available Abstract Kartagener syndrome consists of congenital bronchiectasis, sinusitis, and total situs inversus in half of the patients. A patient diagnosed with Kartagener syndrome was reffered to our department due to 3-vessel coronary disease. An off-pump coronary artery bypass operation was performed using both internal thoracic arteries and a saphenous vein graft. We performed a literature review for cases with Kartagener syndrome, coronary surgery and dextrocardia. Although a few cases of dextrocardia were found in the literature, no case of Kartagener syndrome was mentioned.

    Angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphisms have been associated with acute coronary syndrome (ACS); however, several controversial results have also been found in different studied populations. This hospital-based, emergency room, case-control study in Taiwan retrospectively investigated 111 ACS patients, and 195 non-coronary subjects as a control group, to study the effects of ACE I/D polymorphism in the most urgent ACS patients. ACE I/D polymorphisms were determined by polymerase chain reaction-based assays and their associations with ACS risk, severity, and sudden cardiac death were determined. The ACE DD genotype was associated with ACS incidence. The DD genotype was associated with a significant 4-fold higher risk of ACS in multivariate analysis (odds ratio (OR) = 4.295; 95% confidence interval (CI): 1.436-12.851, p = 0.009), and a 3.35-fold higher risk of acute myocardial infarction. DD genotype carriers also had more than 3-fold higher risks of stenosis in all the three coronary arteries, left anterior descending artery infarction, and anterior wall infarction. In addition, the DD genotype was also associated with a higher risk of sudden cardiac death (OR = 6.484, 95% CI: 1.036-40.598, p = 0.046). This study demonstrated that the ACE DD genotype is an independent risk factor for ACS, and in particular, for acute myocardial infarction. In addition, the ACE DD genotype is also associated with greater ACS severity and a higher risk of sudden cardiac death. ACE genotyping is recommended for patients with a history of ACS, and more intensive preventive care is suggested for patients with the DD genotype.

    Full Text Available Abstract Background Acute coronary syndrome (ACS is a major cause of morbidity and mortality in the western world. Peroxisome proliferator-activated receptor γ (PPARγ plays a key role in the regulation of the energy balance, adipocyte differentiation and lipid biosynthesis. The aim was to investigate if the polymorphism PPARγ2 Pro12Ala, which encodes a less efficient transcription factor, was associated with risk of acute coronary disease and if there were interactions between this polymorphism and factors that modify PPARγ activity, such as alcohol intake, smoking, and use of non-steroidal anti-inflammatory medicine. Methods A case-cohort study including 1031 ACS cases and a sub-cohort of 1703 persons was nested within the population-based prospective study Diet, Cancer and Health of 57,053 individuals. Results Homozygous male variant allele carriers of PPARγ2 Pro12Ala were at higher risk of ACS (HR = 2.12, 95% CI: 1.00–4.48 than homozygous carriers of the Pro-allele. Among men, there was a statistically significant interaction between genotypes and alcohol intake such that homozygous variant allele carriers with a low alcohol intake were at higher risk of ACS (HR = 25.3, CI: 16.5–38.7 compared to homozygous common allele carriers (p for interaction Conclusion In the present study, there were no consistent associations between PPARγ Pro12Ala and risk of ACS, and no consistent interaction with alcohol, BMI, NSAID or smoking in relation to ACS.

    Obstructive sleep apnea (OSA) is frequently associated with acute coronary syndrome (ACS). Screening of sleep-disordered breathing (SDB) has not been previously evaluated in ACS within 72 h in intensive care settings and its management could potentially enhance patients' prognosis. This pilot study assessed the feasibility of SDB screening at the early phase of ACS. All consecutive patients admitted to the coronary care unit (CCU) for ACS without acute heart failure underwent one overnight-attended polysomnography (PSG) within 72 h after admission. A telemonitoring (TM) system was set up to remotely monitor the signals and repair faulty sensors. The 27 recordings were analyzed as respiratory polygraphy (RP) and as PSG, and the results were compared. The TM system allowed successful intervention in 48% of recordings, resulting in excellent quality PSG for 89% of cases. The prevalence of SDB [apnea-hypopnea index (AHI) ≥ 15/h] was 82% and mainly consisted of central SDB and periodic breathing, except three patients with OSA. Compared with PSG, RP underestimated AHI, probably due to the poor sleep efficiency, reduction of slow-wave sleep, and alteration of rapid eye movement sleep. An early SDB screening by remote-attended PSG is feasible in ACS patients shortly after admission to CCU. The TM enhanced the quality of PSG. A high prevalence of central SDB was noticed, for which the etiology remains unknown. Further large-scale studies are needed to determine whether central SDB is an incidental finding in early ACS and whether the presence and severity of SDB have a prognostic impact.

    Acute coronary syndrome (ACS) requires improved diagnostic accuracy through useful, safe and easy-to-apply tools. To obtain an assessment scale for the diagnosis of ACS in patients with chest pain and nondiagnostic electrocardiogram and troponin concentrations. A prospective cohort study included 286 patients treated in the emergency department for chest pain, with normal electrocardiogram and troponin levels. Using multiple logistic regression, we obtained the independent predictors for the diagnosis of ACS. The assessment scale's discriminative power was assessed with the area under the ROC curve. The diagnosis of ACS was confirmed in 103 patients (36%). The final predictive model included 3 endpoints: a history of coronary artery disease, hyperlipidaemia and a score≥6 points on the Geleijnse scale. The area under the ROC curve for the final model was 0.90 (95% confidence interval [95% CI] 0.85-0.93). A threshold of 5 points achieved a sensitivity of 76.7% (95% CI 68-84), a specificity of 91.8% (95% CI 87-95), a positive likelihood ratio of 9.36 (95% CI 5.70-15.40), a negative likelihood ratio of 0.25 (95% CI 18.00-36.00) and an overall diagnostic accuracy of 86.4% (95% CI 82-90). The predictive model was superior to the Geleijnse scale alone. The final scale showed good discriminative capacity for diagnosing ACS and could therefore be of interest for identifying ACS in emergency departments. Nevertheless, the scale needs to be validated in larger multicentre studies. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI). All rights reserved.

    Full Text Available Coronary computed tomography angiography (CCTA has evolved notably over the last decade, gaining an increased amount of temporo-spatial resolution in combination with decreased radiation exposure. The importance of CCTA is emerging especially in vulnerable and young patients who might not have developed a viable collateral vascular network to sustain the circulation to an infarction area during a major adverse coronary event. There are a few well-known markers by which a vulnerable plaque can be assessed and that can predict the subsequent events of sudden myocardial ischemia, such as an increased positive remodeling index (cut-off >1.4, low-attenuation plaque (cut-off 0.7, and napkin-ring sign (NRS. This manuscript presents a series of 3 clinical cases of young patients experiencing symptoms and signs of myocardial ischemia who underwent CCTA in order to assess the composition and functional characteristics of atherosclerotic plaques and their repercussion in developing an acute coronary syndrome.

    In rural areas of Canada, people with acute coronary syndromes (ACS) can wait up to 32 hours for transfer for diagnostic cardiac catheterization (CATH). While awaiting CATH, it is critical that pain and anxiety management be optimal to preserve myocardial muscle and minimize the risk of further deterioration. The aim of this study was to examine the relationship between clinical management, cardiac pain intensity, and state anxiety for rural ACS patients awaiting diagnostic CATH. In a prospective, descriptive-correlational repeated-measures design involving 121 ACS rural patients, we examined the associations of analgesic and nitroglycerin administration with cardiac pain intensity (numeric rating scale) and state anxiety (Spielberger State Anxiety Inventory) and also nurses' pain knowledge and attitudes (Toronto Pain Management Inventory-ACS Version and Knowledge and Attitudes Survey Regarding Pain) using linear mixed models. The mean age of patients was 67.6 ± 13, 50% were men, and 60% had unstable angina and the remainder had non-ST-elevated myocardial infarction. During follow-up, cardiac pain intensity scores remained in the mild range from 1.1 ± 2.2 to 2.4 ± 2.7. State anxiety ranged from 44.0 ± 7.2 to 46.2 ± 6.6. Cumulative analgesic dose was associated with a reduction in cardiac pain by 1.0 points (numeric rating scale, 0-10) (t108 = -2.5; SE, -0.25; confidence interval, -0.45 to -0.06; P = .013). Analgesic administration was not associated with state anxiety. Over the course of follow-up, ACS patients reported consistently high anxiety scores. Whereas cardiac pain declines in most patients in the early hours after admission, many patients experience a persistent anxious state up to 8 hours later, which suggest that development and testing of protocols for anxiety reduction may be needed. More urgently, the development and examination of a treatment intervention, early on in the ACS trajectory, are warranted that targets pain and anxiety for those for

    Full Text Available Abstract Background Studies of chronic diseases are associated with a financial burden on households. We aimed to determine if survivors of acute coronary syndrome (ACS experience household economic burden and to quantify any potential burden by examining level of economic hardship and factors associated with hardship. Methods Australian patients admitted to hospital with ACS during 2-week period in May 2012, enrolled in SNAPSHOT ACS audit and who were alive at 18 months after index admission were followed-up via telephone/paper survey. Regression models were used to explore factors related to out-of-pocket expenses and economic hardship. Results Of 1833 eligible patients at baseline, 180 died within 18 months, and 702 patients completed the survey. Mean out-of-pocket expenditure (n = 614 in Australian dollars was A$258.06 (median: A$126.50 per month. The average spending for medical services was A$120.18 (SD: A$310.35 and medications was A$66.25 (SD: A$80.78. In total, 350 (51 % of patients reported experiencing economic hardship, 78 (12 % were unable to pay for medical services and 81 (12 % could not pay for medication. Younger age (18–59 vs ≥80 years (OR: 1.89, no private health insurance (OR: 2.04, pensioner concession card (OR: 1.80, residing in more disadvantaged area (group 1 vs 5 (OR: 1.77, history of CVD (OR: 1.47 and higher out-of-pocket expenses (group 4 vs 1 (OR: 4.57 were more likely to experience hardship. Conclusion Subgroups of ACS patients are experiencing considerable economic burden in Australia. These findings provide important considerations for future policy development in terms of the cost of recommended management for patients.

    A 53-year-old woman was admitted to our chest pain unit because of an acute coronary syndrome (non ST-elevation myocardial infarction). She complained of asthma, chronic sinusitis and involuntary weight loss, occasional fever and night sweats over the past six months. Coronary angiography did not show any signs of macroscopic coronary artery disease, while echocardiography demonstrated a hemodynamically not significant pericardial effusion. Magnetic resonance imaging of the heart revealed a subendocardial scar, extension and localization pointing to a vascular genesis. Thoracic computed tomography revealed pulmonary opacities and blood tests showed an eosinophilia, leading to the clinical diagnosis of Churg-Strauss syndome. The patient responded quickly to oral steroids, and blood parameters returned to normal. Acute coronary syndrome in youngish patients without classical cardiovascular risk factors is suggestive for myocarditis but also for vasculitis. Churg-Strauss syndrome usually responds quickly to immunosuppressive therapy, associated with a rather good prognosis without high mortality. © Georg Thieme Verlag KG Stuttgart · New York.

    We assessed Takotsubo (ampulla) cardiomyopathy compared with acute coronary syndrome (ACS) using two-dimensional echocardiography and 99m Tc-tetrofosmin myocardial SPECT. We examined 10 patients with Takotsubo cardiomyopathy and 16 with ACS at the time of emergency admission (acute phase), at three to nine days after the attack (subacute phase) and at one month after the attack (chronic phase). The left ventricle was divided into nine regions on echocardiograms and SPECT images, and the degree of abnormalities in each region was scored in five grades from normal (0) to severely abnormal (4). Coronary angiography revealed total or subtotal occlusion in patients with ACS but no stenotic legions in those with Takotsubo cardiomyopathy. The amount of ST segment elevation (mm) was 7.9±3.4 in patients with Takotsubo cardiomyopathy and 7.3±3.7 in those with ACS (N.S.). Abnormal wall motion scores on echocardiograms were 13.8±4.4, 4.4±3.8 and 1.8±2.3 during the acute, subacute and chronic phases in patients with Takotsubo cardiomyopathy, and 13.9±4.0, 11.7±3.7, 7.6±4.2, respectively in patients with ACS. The value of MB fraction of creatine phosphokinase (IU/l) was 34±23 in patients with Takotsubo cardiomyopathy and 326±98 in those with ACS (p 99m Tc-tetrofosmin myocardial SPECT were 11.4±3.2, 3.2±3.3 and 0.7±1.1 during the acute, subacute and chronic phases respectively, in patients with Takotsubo cardiomyopathy, and 15.8±4.1, 13.5±4.4, 8.2±4.4, respectively, in those with ACS. The numbers of myocardial segments that did not uptake 99m Tc-tetrofosmin during the acute phase were 0.5±0.8 and 3.6±2.8 in patients with Takotsubo cardiomyopathy and ACS, respectively. Impaired coronary microcirculation might be a causative mechanism of Takotsubo cardiomyopathy. (author)

    La prévalence des maladies cardiovasculaires connaît une croissance rapide dans les pays en développement, entraînant une incidence croissante du syndrome coronarien aigu (SCA. Les modalités de diagnostic et de traitement de cette maladie continuent d’évoluer, et il convient de tenir compte des ressources locales lors de la réalisation d’un diagnostic et la détermination des options thérapeutiques. Cet article constitue un guide à la prise en charge du SCA fondé sur l’expérience, et fournit des recommandations spécifiques destinées aux médecins hospitaliers travaillant dans les pays à bas et moyen revenu. Le diagnostic du SCA, y compris les SCA sans élévation du ST et avec élévation du ST, se concentre sur la stratification du risque, la vigilance relative aux manifestations subtiles ou atypiques, et la prise en considération d’autres causes des douleurs poitrinaires. Le processus de diagnostic implique l’évaluation des facteurs de risque, la connaissance des antécédents médicaux défavorables et les conclusions de l’examen physique (des variantes étant susceptibles d’exister dans les différentes populations, ainsi que l’utilisation de tests de diagnostic appropriés. Il est recommandé d’utiliser de l’aspirine à titre de traitement initial, parallèlement à un antiagrégant plaquettaire supplémentaire. Le prasugrel est préféré au clopidogrel si le patient présente un SCA avec élévation du ST et qu’une intervention coronaire percutanée (ICP est prévue. La bivalidurine devrait être le premier choix pour éviter la coagulation dans les SCA avec élévation du ST, suivie de l’enoxaparine (qui ne nécessite pas de perfusion, puis d’héparine non fractionnée. Pour les patients présentant un SCA sans élévation du ST et en cas de risque de saignement accru, le fondaparinux devrait être envisagé à la place de l’énoxaparine.

    CD147 is an important molecule in the inflammation and proteolysis process. This molecule crucially contributes to the initial and progression of atherosclerotic lesions. A single nucleotide polymorphism in CD147 gene, the rs8259 T/A in the 3'-untranslated region, is responsible for its expression in various cells. This study assessed whether the genetic variation rs8259 is associated with acute coronary syndrome (ACS) and CD147. A total of 943 ACS subjects and 439 stable angina subjects, and 851 controls were genotyped for rs8259 polymorphism by polymerase chain reaction restriction fragment length polymorphism and DNA-sequencing method. Plasma soluble CD147 (sCD147) level was measured by enzyme-linked immunosorbent assay. CD147 mRNA and protein expression in peripheral blood mononuclear cells were tested by real-time quantitative polymerase chain reaction and western blot, respectively. We found that TT genotype and T-allele frequency of CD147 rs8259 in ACS patients were much lower than the other patient groups. Significant difference was not observed between stable angina and controls. CD147 T allele was negatively related to ACS. ACS patients exhibited the highest CD147 expression in peripheral blood mononuclear cells and plasma sCD147 level. The plasma sCD147 levels in the culprit vessel were higher than those in the radial artery. In ACS patients, AA gene carriers had the highest CD147 levels, whereas TT gene carriers had the lowest CD147 levels. Linear regression analysis showed that genotypes and disease conditions contributed 49% to the change of the plasma CD147 level. These results suggested that the single nucleotide polymorphism of CD147 gene rs8259 T/A was associated with ACS susceptibility. Allele T gene may decrease the relative risk of suffering from ACS through downregulation of CD147 expression.

  3. Friable but treatable: coronary artery dissections in Ehlers-Danlos syndrome.

    Zago, Alexandre C; Matte, Bruno S

    2013-01-01

    Vascular Ehlers-Danlos syndrome is a rare connective tissue disorder associated with arterial dissection or rupture. Percutaneous coronary intervention (PCI) is often critical in patients with this syndrome because their coronary arteries are prone to dissection, enhancing the risk of stent borders dissection when conventional stent deployment pressures are used. Coronary artery bypass graft (CABG) treatment for these patients may also raise concerns because the left internal mammary artery is probably friable. Therefore, coronary artery revascularization in vascular Ehlers-Danlos syndrome either using PCI or CABG is challenging due to the arteries friability. A small number of cases have been published describing the friability of the vessels and associated complications; nevertheless, the optimum treatment remains unclear. We report the case of a 54-year-old woman treated successfully with PCI and CABG in two different acute coronary syndrome episodes, in which specific technical issues related to both procedures were decisive.

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

    2012-12-01

    BACKGROUND & HYPOTHESIS: Data on the clinical characteristics and outcome of patients presenting with acute coronary syndrome (ACS) according to their marital status is not clear. A total of 5334 patients presenting with ACS in 65 hospitals in 6 Middle East countries in the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2) were studied according to their marital status (5024 married, 100 single, and 210 widowed patients). When compared to married patients, widowed patients were older and more likely to be female. Widowed patients were more likely to have diabetes mellitus, hypertension, history of heart failure, and peripheral vascular disease and were less likely to be tobacco users when compared to the other groups. Widowed patients were also more likely to present with atypical symptoms and have advanced Killip class. Widowed patients were more likely to present with non-ST-elevation myocardial infarction (NSTEMI) when compared to the other 2 groups. Widowed patients were more likely to have heart failure (P = 0.001), cardiogenic shock (P = 0.001), and major bleeding (P = 0.002) when compared to the other groups. No statistically significant difference was observed in regard to duration of hospital stay, door to needle time in STEMI patients, or cardiac arrhythmias between the various groups. Widowed patients had higher in-hospital, 30-day, and 1-year mortality rates (P = 0.001). Marital status was an independent predictor for in-hospital mortality. Widowed marital status was associated with worse cardiovascular risk profile, and worse in-hospital and 1-year outcome. Future work should be focused on whether the provision of psychosocial support will result in improved outcomes among this high-risk group. © 2012 Wiley Periodicals, Inc.

The latest guidelines for ACS recommend the combined drug regimen, comprising aspirin, P2Y12 inhibitor, angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker, β-blocker, and statin, at discharge after ACS treatment to reduce recurrent ischemic cardiovascular events. This study aimed to examine prescription patterns of secondary prevention drugs in Korean patients with ACS after hospital discharge, to access the appropriateness of secondary prevention drug therapy for ACS, and to evaluate whether to persistently use discharge medications for 18 months.Methods: This study was retrospectively conducted with the patients who were discharged from the tertiary hospital, located in South Korea, after ACS treatment between September 2009 and August 2013. Data were collected through electronic medical record.Results: Among 3,676 patients during the study period, 494 were selected based on inclusion and exclusion criteria. The regimen of aspirin + clopidogrel + β-blocker + angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker + statin was prescribed to 374 (75.71% patients with ACS at discharge. Specifically, this regimen was used in 177 (69.69% unstable angina patients, 44 (70.97% non-ST-segment elevation myocardial infarction patients, and 153 (85.96% ST-segment elevation myocardial infarction patients.

    Objectives This study sought to determine if there is an association between bleed location and clinical outcomes in acute coronary syndromes (ACS) patients. Background The prognostic significance of bleeding location among ACS patients undergoing cardiac catheterization is not well known. Methods We analyzed in-hospital bleeding events among 9,978 patients randomized in the SYNERGY (Superior Yield of the New Strategy of Enoxaparin, Revascularization, and Glycoprotein IIb/IIIa Inhibitors) study. Bleeding events were categorized by location as access site, systemic, surgical, or superficial, and severity was graded using the GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) definition. We assessed the association of each bleeding location and severity with 6-month risk of death or myocardial infarction using a multicovariate-adjusted Cox proportional hazard model. Results A total of 4,900 bleeding events were identified among 3,694 ACS patients with in-hospital bleeding. Among 4,679 GUSTO mild/moderate bleeding events, only surgical and systemic bleeds were associated with an increased risk of 6-month death or myocardial infarction (adjusted hazard ratio [HR]: 2.52 [95% confidence interval (CI): 2.16 to 2.94, and 1.40 [95% CI: 1.16 to 1.69], respectively). Mild/moderate superficial and access-site bleeds were not associated with downstream risk (adjusted HR: 1.17 [95% CI: 0.97 to 1.40], and 0.96 [95% CI: 0.82 to 1.12], respectively). Among 221 GUSTO severe bleeds, surgical bleeds were associated with the highest risk (HR: 5.27 [95% CI: 3.80 to 7.29]), followed by systemic (HR: 4.48 [95% CI: 2.98 to 6.72]), and finally access-site bleeds (HR: 3.57 [95% CI: 2.35 to 5.40]). Conclusions Among ACS patients who develop in-hospital bleeding, systemic and surgical bleeding are associated with the highest risks of adverse outcomes regardless of bleeding severity. Although the most frequent among bleeds, GUSTO mild/moderate access-site bleeding is not

    Full Text Available OBJECTIVE: CD4(+ latency-associated peptide (LAP(+ regulatory T cells (Tregs are a newly discovered T cell subset in humans and the role of these cells in patients with acute coronary syndrome (ACS has not been explored. We designed to investigate whether circulating frequency and function of CD4(+LAP(+ Tregs are defective in ACS. METHODS: One hundred eleven ACS patients (acute myocardial infarction and unstable angina and 117 control patients were enrolled in the study. The control patients consisted of chronic stable angina (CSA and chest pain syndrome (CPS. The frequencies of circulating CD4(+LAP(+ Tregs and the expression of the transmembrane protein glycoprotein-A repetitions predominant (GARP on CD4(+ T cells were determined by flow cytometry. The function of CD4(+LAP(+ Tregs was detected using thymidine uptake. Serum interleukin-10 (IL-10 and transforming growth factor-β protein (TGF-β levels were detected using ELISA and expression of GARP mRNA in peripheral blood mononuclear cells (PBMCs was measured by real time-polymerase chain reaction. RESULTS: We found ACS patients had a significantly lower frequency of circulating CD4(+LAP(+ Tregs, and the function of these cells was reduced compared to controls. The expression of GARP in CD4(+ T cells and the serum levels of TGF-β in ACS patients were lower than those of control patients. The serum levels of IL-10 were similar between the two cohorts. CONCLUSIONS: A novel regulatory T cell subset, defined as CD4(+LAP(+ T cells is defective in ACS patients.

    The aim of the present work was to examine the association of depression and marital status, with the long-term prognosis of acute coronary syndrome (ACS), among a Greek sample of cardiac patients. From October 2003 to September 2004, a sample of 2172 consecutive ACS patients from 6 hospitals was enrolled. In 2013-2014, the 10-year follow-up was performed in 1918 participants. Depressive symptoms were evaluated using the validated CES-D score (range 0-60), while marital status was classified as: single, married/cohabitants, divorced and widowed at the time of entry to the study. Patients in the upper tertile of CES-D (>20 score) had 41% (95%CI 14%, 75%) higher risk of ACS incidence as compared with those in the lowest (marital relationships among ACS patients. Secondary public health care intervention programmes are needed to improve patient outcomes and minimise disease burden in clinical and community setting.

    Coronary heart disease is the most common cause of death worldwide. In the United Kingdom in 2010, over 80,000 deaths were attributed to coronary heart disease, and one in 10 female deaths were due to coronary heart disease. Acute coronary syndrome, a subset of coronary heart disease, was responsible for 175,000 inpatient admissions in the United Kingdom in 2012. While men have traditionally been considered to be at higher risk of acute coronary syndrome, various studies have demonstrated that women often suffer from poorer outcomes following an adverse cardiovascular event. This gap is gradually narrowing with the introduction of advanced interventional strategies and pharmacotherapy. However, a better understanding of these differences is of crucial importance for the improvement of the pharmacological and interventional management of acute coronary syndrome and for the development of possible new gender-specific diagnostic and therapeutic options. The goals of this review are to evaluate gender differences in outcomes in patients with acute coronary syndrome in the current era and identify potential mechanisms behind these differences in outcomes following percutaneous coronary intervention.

    The purpose of this study was to investigate the relationship between heart rate at admission and in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Consecutive ACS patients admitted in 2008-2010 across 58 hospitals in six participant countries of the European Hospital Benchmarking by Outcomes in ACS Processes (EURHOBOP) project (Finland, France, Germany, Greece, Portugal and Spain). Cardiogenic shock patients were excluded. Associations between heart rate at admission in categories of 10 beats per min (bpm) and in-hospital mortality were estimated by logistic regression in crude models and adjusting for age, sex, obesity, smoking, hypertension, diabetes, known heart failure, renal failure, previous stroke and ischaemic heart disease. In total 10,374 patients were included. In both STEMI and NSTE-ACS patients, a U-shaped relationship between admission heart rate and in-hospital mortality was found. The lowest risk was observed for heart rates between 70-79 bpm in STEMI and 60-69 bpm in NSTE-ACS; risk of mortality progressively increased with lower or higher heart rates. In multivariable models, the relationship persisted but was significant only for heart rates >80 bpm. A similar relationship was present in both patients with or without diabetes, above or below age 75 years, and irrespective of the presence of atrial fibrillation or use of beta-blockers. Heart rate at admission is significantly associated with in-hospital mortality in patients with both STEMI and NSTE-ACS. ACS patients with admission heart rate above 80 bpm are at highest risk of in-hospital mortality.

    Both high platelet reactivity (HPR) and Global Registry of Acute Coronary Events (GRACE) risk score have moderate predictive value for major adverse cardiovascular disease (CVD) events in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI), whereas the prognostic significance of GRACE risk score combined with platelet function testing remains unclear. A total of 596 patients with non-ST elevation ACS who underwent PCI were enrolled. The P2Y 12 reaction unit (PRU) value was measured by VerifyNow P2Y 12 assay and GRACE score was calculated by GRACE risk 2.0 calculator. Patients were stratified by a pre-specified cutoff value of PRU 230 and GRACE score 140 to assess 1-year risk of cardiovascular death, non-fatal myocardial infarction (MI), and stent thrombosis. Seventy-two (12.1%) patients developed CVD events during 1-year follow-up. Patients with CVD events had a higher PRU value (244.6 ± 50.9 vs. 203.7 ± 52.0, p risk independently. Compared to patients with normal platelet reactivity (NPR) and GRACE score risk (HR: 5.048; 95% CI: 2.268-11.237; p risk score yielded superior risk predictive capacity beyond GRACE score alone, which is shown by improved c-statistic value (0.871, p = 0.002) as well as net reclassification improvement (NRI 0.263, p risk of adverse CVD events. The combination of platelet function testing and GRACE score predicted 1-year CVD risk better.

    disorder in hyperthyroidism but paroxysmal tachycardia and atrial fibrillation are not rare. This can be explained by increased heart rate, cardiac output, blood volume, coronary artery flow and peripheral oxygen consumption in thyreotoxicosis [9]. Patients with coronary arteriosclerosis can develop angina pectoris during thyreotoxic stage, which can be explained by imbalance between cardiac demand and supply. Myocardial damage is often in thyrotoxic patients with chronic hart failure, together with myocardial infarction in patients without coronary disease [2,6]. Congestive heart failure and atrial fibrillation are relatively resistant to digitalis treatment because of high metabolic turn over of medication and excessive myocardial irritability in hyperthyro-idism [6]. Cardiovascular and myopathic manifestations predominate in older hyperthyroid patients (over 60 years and some of them can have only few symptoms of hyperthyroidism [1-3]. Thyrotoxic state characterized by fatigue, apathy, extreme weakness, low-grade fever and sometimes congestive heart failure are designated as apathetic hyperthyroidism. Such patients have small goiters, mild tachycardia and often cool and dry skin with few eye signs [6]. Patients with subclinical hyperthyroidism are at increased risk for atrial fibrillation [9]. Unstable angina and non-Q myocardial infarction (non ST elevation are acute manifestation of coronary artery disease. The acute coronary syndrome of unstable angina, non-Q myocardial infarction and Q-wave myocardial infarction have atherosclerotic lesions of the coronary arteries as a common pathogenic substrate. Errosions or ruptures of unstable atherosclerotic plaque triggered pathophysiologic processes, resulted in thrombus formation at the site of arterial injury. This leads to abrupt reduction or cessation through the affected vessel. Clinical manifestations of unstable angina and non-Q myocardial infarction are similar and diagnosis of non-Q myocardial infarction is made on

    Full Text Available The harmful effects of particulate matter with an aerodynamic diameter of <2.5 µm (PM2.5 and its association with acute coronary syndrome (ACS has gained increased attention in recent years. Significant associations between PM2.5 and ACS have been found in most studies, although sometimes only observed in specific subgroups. PM2.5-induced detrimental effects and ACS arise through multiple mechanisms, including endothelial injury, an enhanced inflammatory response, oxidative stress, autonomic dysfunction, and mitochondria damage as well as genotoxic effects. These effects can lead to a series of physiopathological changes including coronary artery atherosclerosis, hypertension, an imbalance between energy supply and demand to heart tissue, and a systemic hypercoagulable state. Effective strategies to prevent the harmful effects of PM2.5 include reducing pollution sources of PM2.5 and population exposure to PM2.5, and governments and organizations publicizing the harmful effects of PM2.5 and establishing air quality standards for PM2.5. PM2.5 exposure is a significant risk factor for ACS, and effective strategies with which to prevent both susceptible and healthy populations from an increased risk for ACS have important clinical significance in the prevention and treatment of ACS.

    Introduction: Myocardial bridge is an inborn anomaly of coronary artery development, when a part of it is submerged in a myocard, which is pressing the coronary artery to a systola and restrains coronary blood circulation. Generally this feature of coronary blood circulation does not cause any clinical symptoms because the 85% of coronary blood stream of the left ventricle is provided by diastolic filling. Hemodynamic changes in atherosclerosis, tahicardie, hypertrophie of myocard are leading to the manifestation of clinical symptoms of ischemia. The aim: The purpose of the investigation was to discover the features of clinical development of acute coronary syndrome caused by myocardial bridge of young patients without the features of atherosclerotical harm of coronary arteries. Materials and methods: Eight causes of acute coronary syndrome among patients of 28±8,5 years with myocardial bridge which was revealed during coronary angiography, were investigated. Standardized examination and conservative treatment of patients was held, except for three who have got interventional therapy. Results: According to our investigation, myocardial bridge of all investigated patients was located in the middle of the third front interventricular branch of the left coronary artery. Causes of acute coronary syndrome manifestation were tahicardia, spasms of coronary artery, inducted by iatrogenic factors hypertrophie of myocard, hypertrophic cardiomyopatie. Connection between the manifestation of clinical symptoms and length of tunneled segment which did not depend on the level of systolic compres was discovered. The results of conservative and interventional treatment were analyzed. Conclusions: Myocardial bridge can be the cause of myocardial ischemia among patients without signs of coronary atherosclerosis with additional hemodynamic risk facts such as tahicardia, spasms of coronary artery, hypertrophie of myocard. Clinical symptomatology of the acute coronary syndrome is more

    Blood glucose is known to be elevated in patients presenting with acute coronary syndromes. However a gap in knowledge exists regarding effective management strategies once admitted to acute care units. It is also unknown what factors (if any) predict elevated glucose values during initial presentation. OBJECTIVES of the study were to characterize blood glucose control in patients admitted to the cardiac care unit (CCU) in Qatar and to determine predictive factors associated with high glucose levels (>10 mmol/l) on admission to the CCU. All data for this study were obtained from the CCU at Heart Hospital in Doha, Qatar. A retrospective chart review was completed for patients admitted to the CCU in Qatar from October 1st, 2012 to March 31st, 2013, of which 283 were included. Baseline characteristics (age, gender, nationality, medical history, smoking status, type of acute coronary syndrome), capillary and lab blood glucose measurements, and use of insulin were extracted. Time spent in glucose ranges of 10 mmol/1 was calculated manually. Univariate and multivariate logistic regression were performed to assess factors associated with high glucose on admission. The primary analysis was completed with capillary data and a sensitivity analysis was completed using laboratory data. Blood glucose values measured on admission and throughout length of stay in the CCU. Capillary blood glucose data showed majority of time was spent in the range of >10 mmol/l (41.95%), followed by 4-8 mmol/l (35.44%), then 8-10 mmol/l (21.45%), and finally 10 mmol/l on admission (p < 0.05) in a univariate analysis but only diabetes remained significant in a multivariate model (OR 23.3; 95% CI, 11.5-47.3). Diabetes predicts high glucose values on hospital admission for patients with ACS and patients are not being adequately controlled throughout CCU stay.

    The CHA2DS2-VASC score, used for embolic risk stratification in atrial fibrillation (AF), has been reported recently to predict adverse clinical outcomes in patients with acute coronary syndrome (ACS), regardless of having AF. We investigated the correlation between the CHA2DS2-VASC score and contrast-induced nephropathy (CIN) in patients with ACS who underwent urgent percutaneous coronary intervention (PCI). A total of 1,408 patients were enrolled in the study. The CHA2DS2-VASC score was calculated for each patient. Based on the receiver operating characteristic analysis, the study population was divided into 2 groups: CHA2DS2-VASC score ≤3 group (n = 944) and CHA2DS2-VASC score ≥4 group (n = 464). Patients were then reallocated to 2 groups according to the presence or absence of CIN. CIN was defined as a rise in serum creatinine >0.5 mg/dl or >25% increase in baseline within 72 hours after PCI. Overall, 159 cases (11.3%) of CIN were diagnosed. Receiver operating characteristic curve analysis revealed good diagnostic value of CHA2DS2-VASC score in predicting CIN (area under the curve 0.769, 95% confidence interval 0.733 to 0.805; p high score had a higher frequency of CIN (23.9% vs 5.1%; p <0.001), and multivariate analysis identified the CHA2DS2-VASC score of ≥4 as an independent predictor of CIN. In conclusion, CHA2DS2-VASC score can be used as a new, simple, and reliable tool to predict CIN in patients with ACS who underwent urgent PCI. Copyright © 2016 Elsevier Inc. All rights reserved.

    We report a case of Churg-Strauss syndrome (CSS) associated with coronary artery involvement, as demonstrated on coronary CT angiography (CCTA), without specific cardiac symptoms. A 69-year-old male had an 8-year history of bronchial asthma and chronic sinusitis with hypereosinophilia (35 %), polyneuropathy, and a positive antineutrophil cytoplasmic antibody titer, so he was diagnosed with CSS. The patient had no specific cardiac symptoms, but CCTA showed vasculitis and a saccular aneurysm involving the proximal coronary arteries. The 3-year follow-up CCTA demonstrated an increase in the extent of soft-tissue wall thickening and infiltration involving the coronary arteries. Although vasculitis of the major coronary arteries is not a prominent feature of CSS, our case suggests that the coronary arteries may also be targeted in this syndrome.

    The use of electronic cigarettes (e-cigarettes) has risen dramatically in recent years. However, there are currently no published data on the use of e-cigarettes among cardiac patients. The current study reports on the prevalence, reasons for use, and perceived risks of e-cigarettes among patients with post-acute coronary syndrome (ACS). The relationship between e-cigarette use and post-ACS tobacco smoking cessation is also explored. Participants were drawn from a randomized trial of smoking cessation treatments following hospitalization for ACS. The current study focused on 49 participants who completed e-cigarette questions at 24 weeks post-ACS. Of the 49 of participants, 51.0% reported ever use of an e-cigarette and 26.5% reported using an e-cigarette at some time during the 24 weeks post-ACS. Ever use and post-ACS use were both significantly associated with lower rates of abstinence from tobacco cigarettes. Participants perceived e-cigarettes as less harmful to cardiac health than tobacco use and Chantix (varenicline), and similarly harmful as nicotine replacement therapy. Participant perceived likelihood of experiencing a heart attack in the next year was 34.6% if they were to regularly use only e-cigarettes, significantly lower than the perceived risk of recurrence if they were to regularly smoke only tobacco cigarettes (56.2%) and significantly higher than the perceived risk of recurrence if they were to use no nicotine (15.2%). A significant minority of patients are using e-cigarettes post-ACS. Providers should be prepared to discuss potential discrepancies between patient beliefs about the safety of e-cigarettes and the current state of the science.

    Full Text Available Introduction: Acute coronary syndrome (ACS is the leading cause of death in Saudi Arabia as elsewhere. Although, many studies found that South Asians had increased rates of ACS, others did not. The aim of the study is to explore the extent of difference between South Asians and Saudi presentation and risk factors of ACS patients. Materials and Methods: All patients who were diagnosed as having acute myocardial infarction (AMI based on World Health Organization (WHO criteria in 6 month period were included in the study. Results: A total of 190 patients confirmed ACS were included; 121 (63.70% were Saudi, 50 (26.3% were South Asians, and 19 (10.0% were other Arab nationalities. The mean age was 53.9 (SD 14.6. Out of the total South Asians 82% had normal body mass index (BMI ( P = 0.000. Saudi patients were the lowest of the three groups who smoked cigarette and/or shisha (26.6%; P = 0.000. 52.9% of Saudi patients were diabetics and 41.3% were hypertensive ( P = 0.004. More South Asians were presented with chest pain (94% vs 76%. Discussion: South Asians had a double rate of ACS incidence; they were younger, lower socio-economic status, more cigarette smokers, and less diabetics and hypertensive than other patients. An association between the apolipoprotein E (apoE genotype with the incidence of ACS in young South Asian is proposed. Conclusion: South Asians had double rate of ACS incidence; they were younger, lower socio-economic status, more cigarette smokers, and less diabetics and hypertensive than other patients.

    Acute coronary syndrome (ACS), as a common and severe cardiovascular disease, is a leading cause of death and the principal cause of serious long-term disability globally. Clinical risk prediction of ACS is important for early intervention and treatment. Existing ACS risk scoring models are based mainly on a small set of hand-picked risk factors and often dichotomize predictive variables to simplify the score calculation. This study develops a regularized stacked denoising autoencoder (SDAE) model to stratify clinical risks of ACS patients from a large volume of electronic health records (EHR). To capture characteristics of patients at similar risk levels, and preserve the discriminating information across different risk levels, two constraints are added on SDAE to make the reconstructed feature representations contain more risk information of patients, which contribute to a better clinical risk prediction result. We validate our approach on a real clinical dataset consisting of 3464 ACS patient samples. The performance of our approach for predicting ACS risk remains robust and reaches 0.868 and 0.73 in terms of both AUC and accuracy, respectively. The obtained results show that the proposed approach achieves a competitive performance compared to state-of-the-art models in dealing with the clinical risk prediction problem. In addition, our approach can extract informative risk factors of ACS via a reconstructive learning strategy. Some of these extracted risk factors are not only consistent with existing medical domain knowledge, but also contain suggestive hypotheses that could be validated by further investigations in the medical domain.

    Background: Pseudoexfoliation syndrome (PEX) is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation. Aims: The purpose of this study is to determine whether an association exists between ocular pseudoexfoliation and coronary artery disease, aortic aneurysms and peripheric vascular disease. Patients and Methods: 490 patients who underwent coronary angiography (CAG) at Kosuyolu Cardiovascula Research and Training Hospital were included in the study. Patients were evaluated for conventional risk factors such as age, sex, family history, hypertension, diabetes, dislipidemia and smoking. Detailed eye examinations including evaluation of lens were done in all patients. The presence of PEX material in the anterior segment was best appreciated by slit lamp after pupillary dilation. The patients were divided into two groups according to the presence of PEX, and compared for the presence of CAD and other risk factors. Results: CAD was present in 387 patients. 103 patients had normal coronary angiography. 20 (5.2 %) of CAD patients and 4 (3.9%) of normal CAG patients were found to have PEX (p>0.05). There was no significant relationship between CAD and the presence of PEX (p>0.05). When patients were grouped according to the presence of PEX, only age was significantly different between the two groups (r: 0.25, p<0.001). Conclusion: There is no significant relationship between the presence of PEX and CAD. Further studies in larger scales with elderly population may be more valuable. PMID:22558552

    The incremental prognostic value of plasma levels of C-reactive protein (CRP) in relation to GRACE score has not been established in patients with acute coronary syndrome (ACS) with non-ST segment elevation. To test the hypothesis that CRP measurements at admission increases the prognostic value of GRACE score in patients with ACS. A total of 290 subjects, consecutively admitted for ACS, with plasma material obtained upon admission CRP measurement using a high-sensitivity method (nephelometry) were studied. Cardiovascular outcomes during hospitalization were defined by the combination of death, nonfatal myocardial infarction or nonfatal refractory angina. The incidence of cardiovascular events during hospitalization was 15% (18 deaths, 11 myocardial infarctions, 13 angina episodes) with CRP showing C-statistics of 0.60 (95% CI = 0.51-0.70, p = 0.034) in predicting these outcomes. After adjustment for the GRACE score, elevated CRP (defined as the best cutoff point) tended to be associated with hospital events (OR = 1.89, 95% CI = 0.92 to 3.88, p = 0.08). However, the addition of the variable elevated CRP in the GRACE model did not result in significant increase in C-statistics, which ranged from 0.705 to 0.718 (p = 0.46). Similarly, there was no significant reclassification of risk with the addition of CRP in the predictor model (net reclassification = 5.7 %, p = 0.15). Although CRP is associated with hospital outcomes, this inflammatory marker does not increase the prognostic value of the GRACE score.

    The adipose tissue is considered not only a storable energy source, but mainly an endocrine organ that secretes several cytokines. Adiponectin, a novel protein similar to collagen, has been found to be an adipocyte-specific cytokine and a promising cardiovascular risk marker. To evaluate the association between serum adiponectin levels and the risk for cardiovascular events in patients with acute coronary syndromes (ACS), as well as the correlations between adiponectin and metabolic, inflammatory, and myocardial biomarkers. We recruited 114 patients with ACS and a mean 1.13-year follow-up to measure clinical outcomes. Clinical characteristics and biomarkers were compared according to adiponectin quartiles. Cox proportional hazard regression models with Firth's penalization were applied to assess the independent association between adiponectin and the subsequent risk for both primary (composite of cardiovascular death/non-fatal acute myocardial infarction (AMI)/non-fatal stroke) and co-primary outcomes (composite of cardiovascular death/non-fatal AMI/non-fatal stroke/ rehospitalization requiring revascularization). There were significant direct correlations between adiponectin and age, HDL-cholesterol, and B-type natriuretic peptide (BNP), and significant inverse correlations between adiponectin and waist circumference, body weight, body mass index, Homeostasis Model Assessment (HOMA) index, triglycerides, and insulin. Adiponectin was associated with higher risk for primary and co-primary outcomes (adjusted HR 1.08 and 1.07/increment of 1000; p = 0.01 and p = 0.02, respectively). In ACS patients, serum adiponectin was an independent predictor of cardiovascular events. In addition to the anthropometric and metabolic correlations, there was a significant direct correlation between adiponectin and BNP

    Prediabetes is a serious condition that is associated with an increase in cardiovascular morbidity and mortality. We sought to explore the prevalence of prediabetes in patients admitted with acute coronary syndrome (ACS) who were not known to have diabetes and to determine the impact of prediabetes on in-hospital clinical outcomes versus non-diabetic patients. Prospectively, we enrolled 200 patients not known to have diabetes or prediabetes, admitted with ACS. Laboratory tests included fasting plasma glucose (FPG), 2-h plasma glucose (2hPG) after 75 g glucose, HbA1c and lipid profile. Electrocardiogram and echocardiography were done. The primary end-point was in-hospital major adverse cardiovascular events (MACE). Mean age was 50.9 ± 6.8 years (70.5% males). The prevalence of patients with diabetes and patients with prediabetes was 24.5% and 20% respectively. Newly discovered diabetic patients were excluded. Compared with patients without diabetes, prediabetic patients had a higher body mass index (BMI) (P = 0.002) and a longer hospital stay (P = 0.09). In-hospital MACE occurred in 10 (25%) patients with prediabetes versus six (5.4%) in patients without diabetes (P = 0.001). In-hospital MACE correlated with prediabetes (r = 0.28, P prediabetes as the only independent predictor of in-hospital MACE. Prediabetes is common in patients presenting with ACS who are not previously known to have diabetes. Prediabetic patients had worse in-hospital clinical outcomes compared with patients without diabetes. © 2014 Royal Australasian College of Physicians.

  16. Acute coronary syndrome on Friday the 13th: a case for re-organising services?

    Friday the 13th is described as an "unlucky" day that brings misfortune. There are few studies on the question, and none on its effect in cardiovascular patients. The recently misreported "weekend effect" has led to changes in the junior doctor contract in England, providing greater staffing levels on weekends. Should we make similar provisions for Friday the 13th? A retrospective analysis of a large database for patients admitted to hospitals in South Wales with an acute coronary syndrome (ACS) during 1999-2014. Mortality rates for 217 admission day number/name combinations and for Friday the 13th were compared in a Cox proportional hazards regression model. 56 062 ACS patients were identified. There were no significant differences in 13-year mortality between most admission dates (211 of 216) and Friday the 13th. However, a statistically significant reduction in mortality was identified for five dates: Thursday the 15th (HR, 0.77; 95% CI, 0.59-0.999), Wednesday the 18th (HR, 0.76; 95% CI, 0.58-0.99), Monday the 28th (HR, 0.76; 95% CI, 0.57-0.99), Monday the 30th (HR, 0.75; 95% CI, 0.57-0.99) and Tuesday the 31st (HR, 0.71; 95% CI, 0.51-0.99). On most days, there was no difference in the 13-year mortality rate for patients admitted with their first ACS from that for "unlucky" Friday the 13th. However, patients admitted on five day/number combinations were 20-30% more likely to survive at 13 years. These findings could be explained by subgroup analysis inflation of the type I error, although supernatural causes merit further investigation. Our findings should be taken into account in future junior doctor contract negotiations, and may provide a case for reduced staffing levels on these lucky days.

    To determine whether anxiety or depression is associated with takotsubo stress cardiomyopathy (TSCM). A retrospective case-control study was conducted among 73 TSCM cases and 111 acute coronary syndrome (ACS) controls matched for age, sex, and cardiac catheterization date. The study was conducted between May 1, 2009, and February 28, 2010. The Hospital Anxiety and Depression Scale was completed by all participants after hospital discharge. The Hospital Anxiety and Depression Scale was used to assess psychological distress with measurement of anxiety and depression scores. The presence of a stressful emotional or physical trigger before the TSCM presentation was determined. Univariate testing was performed to quantify the associations between anxiety and depression and TSCM trigger status. Multivariable logistic regression was used to quantify the independent associations between anxiety and depression and TSCM status after controlling for relevant covariates. The mean anxiety score was 6.7 ± 4.7 for TSCM cases versus 5.4 ± 3.4 for ACS controls (P = .06). The mean depression score was 4.3 ± 3.7 for TSCM cases versus 4.0 ± 3.1 for controls (P = .61). Anxiety was particularly associated with TSCM status with an emotional trigger (P = .05). After multivariable adjustment, anxiety (OR = 1.13; 95% CI, 1.01-1.26; P = .03) was associated with TSCM status but depression was not (OR = 0.94; 95% CI, 0.83-1.05; P = .29). In comparison with a control group with ACS, patients who presented with TSCM have higher levels of anxiety but not depression.

    Cardiac troponin is elevated in several clinical settings apart from thrombotic acute coronary syndrome (ACS) and is associated with increased adverse events. It is not clear whether troponin elevation in type II myocardial infarction (MI) is associated with increased cardiovascular events. Our objectives were to identify the cause of mortality in type II MI and to attempt to establish the threshold range of cardiac troponin-I (cTnI) elevation as well as clinical factors associated with adverse outcomes in type II MI. This retrospective cohort study included 245 patients presenting with a noncardiac primary diagnosis associated with cTnI elevation at a single centre from January 2003 to December 2011. Primary outcome was a composite of cardiovascular and noncardiovascular mortality. Secondary outcomes included subsequent stroke, ACS, and heart failure (HF). At 1 year, ACS occurred in 13 patients (5.3%), stroke was seen in 10 (4.1%) patients, and HF occurred in 19 (7.8%) patients. Overall 1-year mortality included 102 events (41.6%), with 10 cardiovascular deaths (9.8%), 65 noncardiovascular deaths (63.7%), and 27 (26.5%) deaths from unknown causes. In multivariable analysis, factors independently associated with increased overall 1-year mortality included cTnI elevation ≥ 4.63 μg/L (odds ratio [OR], 3.37; 95% confidence interval [CI], 1.55-7.34; P = 0.002), age ≥ 70 years (OR, 2.44; 95% CI, 1.40-4.29; P = 0.002), and estimated glomerular filtration rate high after type II MI, the majority of mortality is caused by noncardiovascular events.

    The effect of income status on patient outcome merits investigation during periods of financial crisis. We evaluated the impact of income status on out-of-hospital prognosis in a cohort of acute coronary syndrome (ACS) patients, included in a countrywide study during a period of financial crisis. The study is a secondary analysis of a prospective, multicenter, observational study-the PHAETHON study-enrolling consecutive ACS patients in 37 hospitals in Greece. Patients were classified as low or high income based on the reported net annual household income using as a cut-off point the relative poverty threshold for Greece of 12,000 Euros. The outcome measure was survival free of the primary composite endpoint (cardiovascular death, myocardial infarction, stroke/transient ischemic attack, urgent revascularization and urgent hospitalization due to cardiovascular causes). The study population included 794 patients. The administration rate of evidence-based medications was similar in the low- (n = 455) and high-income (n = 339) groups during hospitalization and upon discharge. In a median follow-up of 189 days (interquartile range: 180-212 days), low-income patients had 92 % higher risk of the combined endpoint as compared to high-income patients [Hazard ratio (HR):1.92, 95 % CI:1.25-2.94, p = 0.003]. The effect of low-income status on the combined outcome remained significant after adjustment for age, gender and depression (HR:1.59, 95 % CI:1.02-2.49; p = 0.043). In a period of financial crisis, low income is a significant and independent predictor of poor out-of-hospital outcome in ACS patients. This association has profound implications and should be taken into consideration by public health policy makers.

    The aim of this study was to evaluate the relationship between weather conditions and daily emergency ambulance calls for acute coronary syndromes (ACS). The study included data on 3631 patients who called the ambulance for chest pain and were admitted to the department of cardiology as patients with ACS. We investigated the effect of daily air temperature ( T), barometric pressure (BP), relative humidity, and wind speed (WS) to detect the risk areas for low and high daily volume (DV) of emergency calls. We used the classification and regression tree method as well as cluster analysis. The clusters were created by applying the k-means cluster algorithm using the standardized daily weather variables. The analysis was performed separately during cold (October-April) and warm (May-September) seasons. During the cold period, the greatest DV was observed on days of low T during the 3-day sequence, on cold and windy days, and on days of low BP and high WS during the 3-day sequence; low DV was associated with high BP and decreased WS on the previous day. During June-September, a lower DV was associated with low BP, windless days, and high BP and low WS during the 3-day sequence. During the warm period, the greatest DV was associated with increased BP and changing WS during the 3-day sequence. These results suggest that daily T, BP, and WS on the day of the ambulance call and on the two previous days may be prognostic variables for the risk of ACS.

In ACS patients, serum adiponectin was an independent predictor of cardiovascular events. In addition to the anthropometric and metabolic correlations, there was a significant direct correlation between adiponectin and BNP.

    Full Text Available Background: According to some international studies, patients with acute coronary syndrome (ACS and increased left atrial volume index (LAVI have worse long-term prognosis. However, national Brazilian studies confirming this prediction are still lacking. Objective: To evaluate LAVI as a predictor of major cardiovascular events (MCE in patients with ACS during a 365-day follow-up. Methods: Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated within 48 hours after hospital admission. According to LAVI, two groups were categorized: normal LAVI (≤ 32 mL/m2 and increased LAVI (> 32 mL/m2. Both groups were compared regarding clinical and echocardiographic characteristics, in- and out-of-hospital outcomes, and occurrence of ECM in up to 365 days. Results: Increased LAVI was observed in 78 patients (45%, and was associated with older age, higher body mass index, hypertension, history of myocardial infarction and previous angioplasty, and lower creatinine clearance and ejection fraction. During hospitalization, acute pulmonary edema was more frequent in patients with increased LAVI (14.1% vs. 4.3%, p = 0.024. After discharge, the occurrence of combined outcome for MCE was higher (p = 0.001 in the group with increased LAVI (26% as compared to the normal LAVI group (7% [RR (95% CI = 3.46 (1.54-7.73 vs. 0.80 (0.69-0.92]. After Cox regression, increased LAVI increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012. Conclusion: Increased LAVI is an important predictor of MCE in a one-year follow-up.

    Full Text Available Cardiac tumors can be primary or metastatic, the latter being more frequent and usually of pulmonary or hematologic origin. These patients’ clinical signs are non-specific and the electrocardiogram (ECG can assume many patterns, among which, ST-segment elevation. Nevertheless, associated occlusion of the coronary arteries is rare in these situations.We present a 79-year-old woman with a history of pulmonary neoplasia who was admitted to the emergency department due to atypical chest pain, cough and worsening dyspnea in the previous 3 days. The ECG revealed an ST-segment elevation in the anterolateral and inferolateral leads, despite normal blood work, namely normal troponin. Due to the disparity between the patient’s symptoms and the ECG findings, a decision was made not to proceed to primary angioplasty, but to further investigate with echocardiography, which revealed a mass localized in the anterolateral and inferolateral left ventricle walls, confirmed by computed tomography. The patient was admitted in the medical ward for symptomatic management. Her clinical condition gradually deteriorated due to the disease’s natural evolution and she died two weeks later.This case highlights the importance to keep in mind differential diagnoses to acute coronary syndromes, when a ST-segment elevation is encountered on an ECG.

    Matrix metalloproteinases (MMPs) are a family of zinc metallo-endopeptidases secreted by cells and are responsible for much of the turnover of matrix components. Several studies have shown that MMPs are involved in all stages of the atherosclerotic process, from the initial lesion to plaque rupture. Recent evidence suggests that MMP activity may facilitate atherosclerosis, plaque destabilization, and platelet aggregation. In the heart, matrix metalloproteinases participate in vascular remodeling, plaque instability, and ventricular remodelling after cardiac injury. The aim of the present article is to review the structure, function, regulation of MMPs and to discuss their potential role in the pathogenesis of acute coronary syndromes, as well as their contribution and usefullness in the setting of the disease.

The QoL was assessed using the MacNew Heart Disease Health-Related Quality of Life questionnaire. The group of females scored lower in all the domains of the MacNew Heart Disease Health-Related Quality of Life questionnaire in the initial measurement (B1, in the measurement after 6 months (B2, and in the long-term follow-up measurement (36 months – B3. Despite the fact that both groups achieved improved QoL, its values were higher in the males. The average growth rate of the QoL score in the period from the sixth month to 36th month was higher in females than in males. In the univariate and multivariate analyses, significant independent predictors with a negative influence on the long-term QoL score included female sex (Ρ=−0.190, β=−0.21, age >60 years (Ρ=−0.255, β=−0.186, and diabetes (Ρ=−0.216, β=−0.216.Conclusion: In a 36-month follow-up of ACS patients treated with PCI, there were no statistically significant differences in QoL between sexes. In the entire cohort, there was improvement in QoL, which was higher in the case of the females studied. For the entire group, significant independent determinants of lower QoL 3

    Since identification of aspartate aminotransferase as the first cardiac biomarker in the 1950s, there have been a number of new markers used for myocardial damage detection over the decades. There have also been several generations of troponin assays, each with progressively increasing sensitivity for troponin detection. Accordingly, the "standard of care" for myocardial damage detection continues to change. The purpose of this paper is to review the clinical utility, biological mechanisms, and predictive value of these various biomarkers in contemporary clinical studies. As of this writing, a fifth "next" generation troponin assay has now been cleared by the US Food and Drug Administration for clinical use in the USA for subjects presenting with suspected acute coronary syndromes. Use of these high-sensitivity assays has allowed for earlier detection of myocardial damage as well as greater negative predictive value for infarction after only one or two serial measurements. Recent algorithms utilizing these assays have allowed for more rapid rule-out of myocardial infarction in emergency department settings. In this review, we discuss novel assays available for the risk assessment of subjects presenting with chest pain, including both the "next generation" cardiac troponin assays as well as other novel biomarkers. We review the biological mechanisms for these markers, and explore the positive and negative predictive value of the assays in clinical studies, where reported. We also discuss the potential use of these new markers within the context of future clinical care in the modern era of higher sensitivity troponin testing. Finally, we discuss advances in new platforms (e.g., mass spectrometry) that historically have not been considered for rapid in vitro diagnostic capabilities, but that are taking a larger role in clinical diagnostics, and whose prognostic value and power promise to usher in new markers with potential for future clinical utility in acute coronary

    Ticagrelor is an orally administered antiplatelet agent used to reduce thrombotic events in patients with acute coronary syndromes. Data from two studies in patients with acute coronary syndromes with large amounts of pharmacokinetic (PK) data (phase IIb DISPERSE-2 study (n = 609)); phase III PLATO PK substudy (n = 6,381)), along with non-linear mixed effects modeling software, were used to develop population PK models for ticagrelor and its metabolite, AR-C124910XX, and to evaluate the impact of demographic and clinical factors on the PK of ticagrelor and AR-C124910XX. 32 covariates relating to disease history, biomarkers, clinical chemistry, and concomitant medications were assessed. A one-compartment model with population mean PK parameters of firstorder absorption rate constant (0.67/h), apparent systemic clearance (14 L/h), and apparent volume of distribution (221 L) was shown to best describe the PK profile of ticagrelor. Patients co-administered moderate CYP3A inducers or inhibitors increased (by 110%, 95% confidence interval (CI), 52 - 192%) or decreased (by 64%, 95% CI, 39 - 73%) apparent ticagrelor clearance, respectively, while habitual smoking decreased apparent ticagrelor clearance by 22% (95% CI, 19 - 25%). Ticagrelor bioavailability was 21% (95% CI, 19 - 22%) lower at treatment initiation (visit 1) versus subsequent visits. Compared with Caucasian patients, ticagrelor bioavailability was 39% (95% CI, 33 - 46%) higher in Asian patients and 18% (95% CI, 6 - 28%) lower in Black patients. In the current analyses, the population PK models developed for ticagrelor and AR-C124910XX described the data obtained in the DISPERSE-2 and PLATO studies well, and were consistent with previous phase I PK studies.

    Full Text Available Abstract Objective: The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. Methods: The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1 and those diagnosed without acute coronary syndrome (Group 2. Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. Results: There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Conclusion: Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

Recently the involvement of infectious agents as a risk factor for Acute Coronary syndrome is drafted. So this study was designed to investigate the probable association between Acute Coronary syndrome and Helicobacter pylori infection.   Methods: This case-control study was carried out on 300 hospitalized patients with the diagnosis of Acute Coronary syndrome (UA and MI and 300 hospitalized patients without the history of coronary heart disease. Anti Helicobacter pylori Antibody level was determined by as an indicator of infection history. Using chi-square and t- test the results were analyzed in SPSS software.   Results: Results showed that 79 patients (26.3% in control group and 122 patients (40.6% in case group were seropositive and the difference was significant. Relationship between cronory diseases risk factors and levels of IgG was not significant. Also the results showed that the rate of hypertension in seropositive patients in case group was significantly upper than control group.   Conclusion: Regarding the findings of this study we can conclude that Helicobacter pylori infection probably is a risk factor for Acute Coronary Syndrome. Thus, further studies are needed to elucidate the association between Helicobacter pylori infection and Acute Coronary Syndrome.

    Progression of stable coronary artery disease (CAD) towards acute coronary syndrome (ACS) is a dynamic and heterogeneous process with many intertwined constituents, in which a plaque destabilising sequence could lead to ACS within short time frames. Current CAD risk assessment models, however, are not designed to identify increased vulnerability for the occurrence of coronary events within a precise, short time frame at the individual patient level. The BIOMarker study to identify the Acute risk of a Coronary Syndrome (BIOMArCS) was designed to evaluate whether repeated measurements of multiple biomarkers can predict such 'vulnerable periods'. BIOMArCS is a multicentre, prospective, observational study of 844 patients presenting with ACS, either with or without ST-elevation and at least one additional cardiovascular risk factor. We hypothesised that patterns of circulating biomarkers that reflect the various pathophysiological components of CAD, such as distorted lipid metabolism, vascular inflammation, endothelial dysfunction, increased thrombogenicity and ischaemia, diverge in the days to weeks before a coronary event. Divergent biomarker patterns, identified by serial biomarker measurements during 1-year follow-up might then indicate 'vulnerable periods' during which patients with CAD are at high short-term risk of developing an ACS. Venepuncture was performed every fortnight during the first half-year and monthly thereafter. As prespecified, patient enrolment was terminated after the primary end point of cardiovascular death or hospital admission for non-fatal ACS had occurred in 50 patients. A case-cohort design will explore differences in temporal patterns of circulating biomarkers prior to the repeat ACS. Follow-up and event adjudication have been completed. Prespecified biomarker analyses are currently being performed and dissemination through peer-reviewed publications and conference presentations is expected from the third quarter of 2016. Should

    Whereas the coronary artery disease death rate has declined in high-income countries, the incidence of acute coronary syndromes (ACS) is increasing in sub-Saharan Africa, where their management remains a challenge. To propose a consensus statement to optimize management of ACS in sub-Saharan Africa on the basis of realistic considerations. The AFRICARDIO-2 conference (Yamoussoukro, May 2015) reviewed the ongoing features of ACS in 10 sub-Saharan countries (Benin, Burkina-Faso, Congo-Brazzaville, Guinea, Ivory Coast, Mali, Mauritania, Niger, Senegal, Togo), and analysed whether improvements in strategies and policies may be expected using readily available healthcare facilities. The outcome of patients with ACS is affected by clearly identified factors, including: delay to reaching first medical contact, achieving effective hospital transportation, increased time from symptom onset to reperfusion therapy, limited primary emergency facilities (especially in rural areas) and emergency medical service (EMS) prehospital management, and hence limited numbers of patients eligible for myocardial reperfusion (thrombolytic therapy and/or percutaneous coronary intervention [PCI]). With only five catheterization laboratories in the 10 participating countries, PCI rates are very low. However, in recent years, catheterization laboratories have been built in referral cardiology departments in large African towns (Abidjan and Dakar). Improvements in patient care and outcomes should target limited but selected objectives: increasing awareness and recognition of ACS symptoms; education of rural-based healthcare professionals; and developing and managing a network between first-line healthcare facilities in rural areas or small cities, emergency rooms in larger towns, the EMS, hospital-based cardiology departments and catheterization laboratories. Faced with the increasing prevalence of ACS in sub-Saharan Africa, healthcare policies should be developed to overcome the multiple

Recruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed. More than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (Pmetabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

    The epidemiology and management of patients with acute coronary syndromes (ACSs) have evolved. We aimed to describe recent demographics and therapeutic changes in the Italian ACS population. We analyzed data from 2 multicenter consecutive Italian registries (the EYESHOT [EmploYEd antithrombotic therapies in patients with acute coronary Syndromes HOspitalised in iTalian cardiac care units] and START-ANTIPLATELET registries) enrolling patients with ACS between December 2013 and June 2016. An overall population of 3756 patients with ACS was enrolled: 2585 in the EYESHOT and 1171 in the START-ANTIPLATELET. Compared with the EYESHOT, patients in the START-ANTIPLATELET registry presented more frequently with ST-segment elevation myocardial infarction and were more often smokers and dyslipidemic (all P START-ANTIPLATELET (all P START-ANTIPLATELET compared with the EYESHOT. The START-ANTIPLATELET and EYESHOT registries provide consecutive snapshots in the contemporary management of patients with ACS in Italy, showing important changes in both demographic characteristics and treatment strategies.

    The question of whether gender-related disparities still exist in the treatment and outcomes of patients presenting with acute coronary syndromes (ACS) remains controversial. Using data from 4 registries spanning a decade, we sought to determine whether sex-related differences have persisted over time and to examine the treating physician's rationale for adopting a conservative management strategy in women compared with men. From 1999 to 2008, 14,196 Canadian patients with non-ST-segment elevation ACS were recruited into the Acute Coronary Syndrome I (ACSI), ACSII, Global Registry of Acute Coronary Events (GRACE/GRACE(2)), and Canadian Registry of Acute Coronary Events (CANRACE) prospective multicenter registries. Women in the study population were found to be significantly older than men and were more likely to have a history of heart failure, diabetes, or hypertension. Fewer women were treated with thienopyridines, heparin, and glycoprotein IIb/IIIa inhibitors compared with men in GRACE and CANRACE. Female gender was independently associated with a lower in-hospital use of coronary angiography (adjusted odds ratio 0.76, 95% CI 0.69-0.84, P < .001) and higher in-hospital mortality (adjusted odds ratio 1.26, 95% CI 1.02-1.56, P = .036), irrespective of age (P for interaction =.76). Underestimation of patient risk was the most common reason for not pursuing an invasive strategy in both men and women. Despite temporal increases in the use of invasive cardiac procedures, women with ACS are still more likely to be treated conservatively, which may be due to underestimation of patient risk. Furthermore, they have worse in-hospital outcomes. Greater awareness of this paradox may assist in bridging the gap between current guidelines and management practices. Copyright © 2012 Mosby, Inc.

    Full Text Available Objectives: The association between educational status and 10-year risk for acute coronary syndrome (ACS and all-cause mortality was evaluated. Methods: From October 2003 to September 2004, 2172 consecutive ACS patients from six Greek hospitals were enrolled. In 2013 to 2014, a 10-year follow-up (2004-2014 assessment was performed for 1918 participants (participation rate, 88%. Each patient’s educational status was classified as low (14 years. Results: Overall all-cause mortality was almost twofold higher in the low-education group than in the intermediate-education and high-education groups (40% vs. 22% and 19%, respectively, p<0.001. Additionally, 10-year recurrent ACS events (fatal and non-fatal were more common in the low-education group than in the intermediate-education and high-education groups (42% vs. 30% and 35%, p<0.001, and no interactions between sex and education on the investigated outcomes were observed. Moreover, patients in the high-education group were more physically active, had a better financial status, and were less likely to have hypertension, diabetes, or ACS than the participants with the least education (p<0.001; however, when those characteristics and lifestyle habits were accounted for, no moderating effects regarding the relationship of educational status with all-cause mortality and ACS events were observed. Conclusions: A U-shaped association may be proposed for the relationship between ACS prognosis and educational status, with participants in the low-education and high-education groups being negatively affected by other factors (e.g., job stress, depression, or loneliness. Public health policies should be aimed at specific social groups to reduce the overall burden of cardiovascular disease morbidity.

    Hyperglycemia negatively affects cardiovascular variables that are also adversely affected by increased geomagnetic activity. It is likely that geomagnetic storms (GS) could have a stronger negative impact on these patients. We analyzed data on 1548 randomly selected patients with acute coronary syndrome (ACS) who were admitted inpatient treatment in Kaunas city, during 2000-2003. We evaluated the associations of GS, solar proton events (SPE), and high-speed solar wind (HSSW) (solar wind speed ≥600 km/s) with the risk of ACS in patients with diabetes mellitus (DM) and the metabolic syndrome (MS) by using logistic regression with categorical predictors. During days of HSSW, the risk of ACS in DM patients increased by 1.95 times (OR = 1.95, 95 % CI 1.36-2.79) as compared to days without either of these events or 2 days prior to or after them. In the multivariate model, the risk of ACS in DM patients was associated with days of HSSW and 1-2 days after (OR = 1.40, 95 % CI 1.01-1.93), with days of GS lasting >1 day and occurring on days of HSSW or 1-2 days after (OR = 2.31, 95 % CI 1.28-4.17), and with the onset of SPE (OR = 2.72 (1.09-6.83)). The risk of ACS in MS patients was associated with days of GS and 1-2 days prior or after GS (OR = 1.31 (1.00-1.73)); an additional impact was established if these days coincided with days of HSSW or 1-2 days before (OR = 2.16 (1.39-3.35)). These findings suggest that not only GS but also HSSW and changes in space weather conditions prior to SPE affect the human cardiovascular system.

    Non-ST elevation acute coronary syndrome (NSTE-ACS) imposes a significant health and economic burden on a society. Anticoagulants are recommended as standard therapy by various clinical practice guidelines. Fondaparinux was introduced and evaluated in a number of large randomised, controlled trials. This study therefore aimed to determine the cost-effectiveness of fondaparinux versus enoxaparin in the treatment of NSTE-ACS in Thailand. A two-part construct model comprising a one-year decision tree and a Markov model was developed to capture short and long-term costs and outcomes from the perspective of provider and society. Effectiveness data were derived from OASIS-5 trial while bleeding rates were derived from the Thai Acute Coronary Syndrome Registry (TACSR). Costs data were based on a Thai database and presented in the year of 2013. Both costs and outcomes were discounted by 3% annually. A series of sensitivity analyses were performed. The results showed that compared with enoxaparin, fondaparinux was a cost-saving strategy (lower cost with slightly higher effectiveness). Cost of revascularisation with major bleeding had a greater impact on the amount of cost saved both from societal and provider perspectives. With a threshold of 160,000 THB ((4,857.3 USD) per QALY in Thailand, fondaparinux was about 99% more cost-effective compared with enoxaparin. Fondaparinux should be considered as a cost-effective alternative when compared to enoxaparin for NSTE-ACS based on Thailand's context, especially in the era of limited healthcare resources.

    Patients with suspected or confirmed non-ST-elevation acute coronary syndrome (ACS) constitute a large and heterogeneous group. Measurements of renal function such as serum creatinine and estimation of creatinine clearance carry independent prognostic information in this population. Cystatin C is a new and better marker of renal function than creatinine. The aim was therefore to evaluate the prognostic value of cystatin C in this population. Cystatin C was analyzed on admission in 726 patients admitted because of symptoms suggestive of an acute coronary syndrome and no ST-segment elevations. Patients were followed up with regard to death and myocardial infarction for a median of 40 and 6 months, respectively. The median cystatin C level was 1.00 mg/L (25th to 75th percentile, 0.83 to 1.24 mg/L). The risk of death during follow-up increased with increasing levels of cystatin C. In the group with non-ST-elevation ACS, patients in the second, third, and fourth quartiles had a relative risk of subsequent death of 1.8 (95% CI, 0.6 to 5.3), 3.2 (95% CI, 1.2 to 8.5), and 11.7 (95% CI, 4.7 to 29.3) compared with the lowest quartile. In Cox regression models including well-known predictors of outcome, cystatin C level was independently associated with mortality but not with the risk of subsequent myocardial infarction. In a comparison of the markers of renal function in receiver-operating curve analyses, cystatin C had the best ability to discriminate between survivors and nonsurvivors. A single measurement of cystatin C will substantially improve the early risk stratification of patients with suspected or confirmed non-ST-elevation ACS.

    The prevalence of coronary artery disease is on the rise as the life expectancy of the population increases. However, treatment of acute coronary syndrome in the elderly patients has its own problems that have not been thoroughly addressed in the clinical trials. Since these patients are generally fragile and have multiple co-morbidities, the course of acute coronary syndrome can frequently be complicated. Infection, which co-exists either at the initial presentation or is acquired during the hospital stay, is a condition about which there is little published data. Therefore, in our study, we wanted to assess the impact of infection on mortality in octogenarians who have acute coronary syndrome METHODS: We retrospectively analyzed the data of 174 octogenarians who had been admitted to the coronary care unit with acute coronary syndrome. All-cause mortality was defined as the primary endpoint of the study. Overall 53 octogenarian patients (30.5%) had an infection along with acute coronary syndrome. The mean duration of follow-up was 10 months (1-25 months). Both in-hospital and long-term mortality were higher in these patients (18.9% vs 6.6%, p = 0.01; 52.8% vs 27.5%, p < 0.01; respectively). Kaplan-Meier analysis also showed lower cumulative survival. (p [log-rank] = 0.002). In multivariate Cox regression analysis; undergoing coronary angiography, infection (HR 1.96, 95% CI 1.15-3.34, p = 0.01), left ventricular ejection fraction and maximum C reactive protein levels were found as independent predictors of long-term survival. Infection in octogenarians who were admitted due to acute coronary syndrome was frequent and increased their mortality substantially. Copyright © 2018 Elsevier B.V. All rights reserved.

    To compare the discriminative performance of the PURSUIT, GUSTO-1, GRACE, SRI and EMMACE risk models, assess their performance among risk supergroups and evaluate the EMMACE risk model over the wider spectrum of acute coronary syndrome (ACS). Observational study of a national registry. All acute hospitals in England and Wales. 100 686 cases of ACS between 2003 and 2005. Model performance (C-index) in predicting the likelihood of death over the time period for which they were designed. The C-index, or area under the receiver-operating curve, range 0-1, is a measure of the discriminative performance of a model. The C-indexes were: PURSUIT C-index 0.79 (95% confidence interval 0.78 to 0.80); GUSTO-1 0.80 (0.79 to 0.81); GRACE in-hospital 0.80 (0.80 to 0.81); GRACE 6-month 0.80 (0.79 to 0.80); SRI 0.79 (0.78 to 0.80); and EMMACE 0.78 (0.77 to 0.78). EMMACE maintained its ability to discriminate 30-day mortality throughout different ACS diagnoses. Recalibration of the model offered no notable improvement in performance over the original risk equation. For all models the discriminative performance was reduced in patients with diabetes, chronic renal failure or angina. The five ACS risk models maintained their discriminative performance in a large unselected English and Welsh ACS population, but performed less well in higher-risk supergroups. Simpler risk models had comparable performance to more complex risk models. The EMMACE risk score performed well across the wider spectrum of ACS diagnoses.

  10. Utility of the History and Physical Examination in the Detection of Acute Coronary Syndromes in Emergency Department Patients

    Full Text Available Chest pain accounts for approximately 6% of all emergency department (ED visits and is the most common reason for emergency hospital admission. One of the most serious diagnoses emergency physicians must consider is acute coronary syndrome (ACS. This is both common and serious, as ischemic heart disease remains the single biggest cause of death in the western world. The history and physical examination are cornerstones of our diagnostic approach in this patient group. Their importance is emphasized in guidelines, but there is little evidence to support their supposed association. The purpose of this article was to summarize the findings of recent investigations regarding the ability of various components of the history and physical examination to identify which patients presenting to the ED with chest pain require further investigation for possible ACS. Previous studies have consistently identified a number of factors that increase the probability of ACS. These include radiation of the pain, aggravation of the pain by exertion, vomiting, and diaphoresis. Traditional cardiac risk factors identified by the Framingham Heart Study are of limited diagnostic utility in the ED. Clinician gestalt has very low predictive ability, even in patients with a non-diagnostic electrocardiogram (ECG, and gestalt does not seem to be enhanced appreciably by clinical experience. The history and physical alone are unable to reduce a patient’s risk of ACS to a generally acceptable level (<1%. Ultimately, our review of the evidence clearly demonstrates that “atypical” symptoms cannot rule out ACS, while “typical” symptoms cannot rule it in. Therefore, if a patient has symptoms that are compatible with ACS and an alternative cause cannot be identified, clinicians must strongly consider the need for further investigation with ECG and troponin measurement.

    Red cell distribution width (RDW), a routine component of the complete blood count (CBC), measures variation in the size of circulating erythrocytes. It has been associated with several clinical outcomes in cardiovascular disease. We sought to strengthen the association between RDW and mortality in patients admitted for acute coronary syndrome (ACS) by pooling together data from available studies. Studies that fulfilled the following were identified for analysis: 1) observational; 2) included patients admitted for ACS; 3) reported data on all-cause or cardiovascular (CV) mortality in association with a low or high RDW; and 4) used logistic regression analysis to control for confounders. Using MEDLINE, Clinical Key, ScienceDirect, Scopus, and Cochrane Central Register of Controlled Trials databases, a search for eligible studies was conducted until January 9, 2017. The quality of each study was evaluated using the Newcastle-Ottawa Quality Assessment Scale. Our primary outcome of interest was all-cause or CV mortality. We also investigated the impact of RDW on major adverse cardiovascular events (MACEs) for the studies that reported these outcomes. Review Manager (RevMan) 5.3 was utilized to perform Mantel-Haenzel analysis of random effects and compute for relative risk. We identified 13 trials involving 10,410 patients, showing that in ACS, a low RDW is associated with a statistically significant lower all-cause or CV mortality (RR 0.35, (95% CI 0.30 to 0.40), P < 0.00001, I 2 = 53%), a finding that was consistent both in the short- and long-term. A low RDW is also associated with lower risk for MACEs after an ACS (RR 0.56, (95% CI 0.51 to 0.61), P < 0.00001, I 2 = 91%). A low RDW during an ACS is associated with lower all-cause or CV mortality and lower risk of subsequent MACEs, providing us with a convenient and inexpensive risk stratification tool in ACS patients.

    Depression is common and associated with poor prognosis in acute coronary syndrome (ACS). There are few reports on the predictors of incident and persistent post-discharge depressive disorders in ACS. This study aimed to investigate the incidence and persistence of depressive disorder over a one year follow-up, and predictors of these outcomes. 1152 patients with recently developed ACS were recruited at baseline, and 828 were followed one year thereafter. Depressive disorder (major and minor) was diagnosed according to DSM-IV criteria, and analyzed according to baseline prevalence, and follow up incidence and persistence. Of 446 baseline participants with depressive disorders, 300 were randomized to a 24-week double blind trial of escitalopram or placebo, while the remaining 146 received medical treatment as usual. Associations of baseline socio-demographic and clinical characteristics with depressive disorder were investigated using logistic regression models. Two-week prevalence, and one-year incidence and persistence of depressive disorder were 38.7%, 13.1%, and 46.3%, respectively. Baseline depressive disorder was independently associated with female, lower educational level, previous ACS and higher heart rate. Incident depressive disorder was independently predicted by current unemployment, family history of depression, higher baseline Hamilton Depression Rating Scale(HAMD) score and lower left ventricular ejection fraction, and persistent depressive disorder by higher baseline HAMD score and the placebo or medical treatment as usual group in the 24-week trial. The generalizability should be considered since this study conducted in a single center. Depressive disorder in ACS patients is common and often persistent, and is associated with baseline characteristics and insufficient treatment. Appropriate detection and treatment of depressive disorder are clearly important in ACS patients. Copyright © 2015 Elsevier B.V. All rights reserved.

    To evaluate the clinical and economic burden of acute coronary syndrome (ACS), a common cardiovascular illness, in the Medicare population. Data from the Medicare Current Beneficiary Survey were analyzed. Patients with incident hospitalization for ACS without similar events during the 6 months prior were included. Outcomes evaluated included inpatient mortality, 30-day mortality and readmission, subsequent hospitalization events, and total direct health care costs. Sample population weights were applied, accounting for multistage sampling design to obtain nationally representative estimates for the US Medicare population. Between March 1, 2002 and December 31, 2006, we identified 795 incident ACS patients (mean age 76 years; 49% male) representing 2,542,211 Medicare beneficiaries. The inpatient mortality rate was 9.71% and the 30-day mortality ranged from 10.96% to 13.93%. The 30-day readmission rate for surviving patients was 18.56% for all causes and 17.90% for cardiovascular disease (CVD)-related diagnoses. The incidence of death since admission was 309 cases per 1000 person-years. Among patients discharged alive, the incidence was 197 for death, 847 for CVD-related admission, and 906 for all-cause admission. During the year when the ACS event occurred, mean annual total direct health care costs per person were US$50,458, with more than half attributable to inpatient hospitalization ($27,609). In this national representative Medicare population, we found a substantial clinical and economic burden for ACS. These findings suggest a continuing unmet medical need for more effective management of patients with ACS. The continuous burden underscores the importance of development of new interventions and/or strategies to improve long-term outcomes.

    Noonan syndrome is a constellation of congenital malformations including heart defects, facial anomalies and short stature. The cardiovascular defects are variable and extensive, with the most common being pulmonary stenosis and hypertrophic cardiomyopathy. Coronary artery anomalies have only been reported in a few cases. We report a child with Noonan syndrome status post pulmonary stenosis and atrial septal defect repair, who developed bilateral coronary artery aneurysms. The aneurysms were diagnosed with both cardiac magnetic resonance imaging and coronary computed tomography angiography. There had been no evidence of them on a cardiac MR exam 5 years previously.

    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. Copyright © 2016 The Authors.

    Full Text Available Aims. The priority of Chinese herbal medicines (CHMs plus conventional treatment over conventional treatment alone for acute coronary syndrome (ACS after percutaneous coronary intervention (PCI was documented in the 5C trial (chictr.org number: ChiCTR-TRC-07000021. The study was designed to evaluate the 10-year effectiveness of CHMs plus conventional treatment versus conventional treatment alone with decision-analytic model for ACS after PCI. Methods and Results. We constructed a decision-analytic Markov model to compare additional CHMs for 6 months plus conventional treatment versus conventional treatment alone for ACS patients after PCI. Sources of data came from 5C trial and published reports. Outcomes were expressed in terms of quality-adjusted life years (QALYs. Sensitivity analyses were performed to test the robustness of the model. The model predicted that over the 10-year horizon the survival probability was 77.49% in patients with CHMs plus conventional treatment versus 77.29% in patients with conventional treatment alone. In combination with conventional treatment, 6-month CHMs might be associated with a gained 0.20% survival probability and 0.111 accumulated QALYs, respectively. Conclusions. The model suggested that treatment with CHMs, as an adjunctive therapy, in combination with conventional treatment for 6 months might improve the long-term clinical outcome in ACS patients after PCI.

    Angina in patients with coronary artery disease is associated with worse quality of life; however, the relationship between angina frequency and resource utilization is unknown. Using data from the MERLIN-TIMI 36 trial, we assessed the association between the extent of angina after an acute coronary syndrome (ACS) and subsequent cardiovascular resource utilization among 5460 stable outpatients who completed the Seattle Angina Questionnaire at 4 months after an ACS and who were then followed for an additional 8 months. Angina frequency was categorized as none (score, 100; 2739 patients), monthly (score, 61 to 99; 1608 patients), weekly (score, 31 to 60; 854 patients), and daily (score, 0 to 30; 259 patients). Multivariable regression models evaluated the association between angina frequency and overall costs attributable to cardiovascular hospitalizations, outpatient visits and procedures, and medications. As compared with no angina, overall costs increased in a graded fashion with higher angina frequency-no angina, $2928 (reference); monthly angina, $3909 (adjusted relative cost ratio, 1.29; 95% CI, 1.21 to 1.39); weekly angina, $4558 (adjusted relative cost ratio, 1.52; 95% CI, 1.48 to 1.67); and daily angina, $6949 (adjusted relative cost ratio, 2.32; 95% CI, 2.01 to 2.69; P for trend 2-fold increase in resource utilization and incremental costs of $4000 after 8 months of follow-up.

    Full Text Available Caroline Schmidt-Lucke, Heinz-Peter SchultheissCharité Medical University Berlin, Campus Benjamin Franklin, Dept. of Cardiology and Pulmology, GermanyAbstract: Non-ST elevation acute coronary syndrome (NSTE-ACS refers to a cardiovascular disorder characterized by intracoronary thrombus formation on a disrupted atherosclerotic plaque with partial or transient occlusion. Generation of thrombin resulting from exposure of collagen leads to activation of platelets and conversion of fibrinogen to fibrin, thus forming a platelet-rich thrombus. The main therapeutic objective is to protect the patient from thrombotic complications, independent of the choice of antithrombotic agents. The management of NSTE myocardial infarction (MI is constantly evolving. For primarily conservative strategy, enoxaparin has been proven superior to unfractioned heparin (UFH. With early invasive strategy providing better clinical outcome compared with conservative strategy, the effectiveness of enoxaparin in reducing death and MI rates is now being reconsidered in the era of poly-pharmacotherapy, early percutaneous coronary interventions and drug eluting stents. Bleeding complications can be minimized by avoiding cross-over from UFH to enoxaparin or vice versa, or by reducing the dosage of enoxaparin. We review the studies of enoxaparin and discuss its current role in the contemporary treatment of NSTE-ACS.Keywords: low-molecular weight heparin, NSTEMI, treatment

  20. Major depression is associated with lower omega-3 fatty acid levels in patients with recent acute coronary syndromes.

    2004-05-01

    Polyunsaturated fatty acids (PUFAs) are intrinsic cell membrane components and closely involved in neurotransmission and receptor function. Lower omega-3 levels are associated with increased risk of coronary artery disease (CAD), increases in cardiac events in CAD patients, and depression. We sought to examine relationships between depression and serum levels of omega-3 and omega-6 PUFAs in patients recovering from acute coronary syndromes (ACS). We carried out a case-control study of serum PUFA levels and current major depression in 54 age- and sex-matched pairs approximately 2 months following ACS. Depressed patients had significantly lower concentrations of total omega-3 and docosahexaenoic acid (DHA), and higher ratios of arachidonic acid (AA) to DHA, AA to eicosapentaenoic acid (EPA), and n-3 to n-6 than controls. There were no baseline differences in any potential risk or protective factors for depression. Results are consistent with previous reports in depressed patients without CAD, and with literature concerning omega-3 levels and risk of CAD events. Dietary, genetic, and hormonal factors may all play a role in both depression and CAD. Both prospective studies and randomized trials are needed to help clarify the interrelationships.

    Full Text Available Background: Coronary heart disease (CHD is the main leading cause of morbidity and mortality in patients with diabetes mellitus. Hyperglycemia on admission was associated with a worse outcome for all patients admitted with ACS. Aim: To correlate the relationship between hyperglycemia with acute coronary syndrome and poor outcome. Methodology: Clinical evaluation of the patients were carried out on arrival to Emergency Department regarding: Initial assessment of patient general condition either stable or not through; ABCDE (air way and cervical spine control, breathing, circulation, neurological dysfunction and exposure. Then determine the characters and types of chest pain. Assess the condition of the patients either stable or unstable which will determine the needed investigations and plane of management. Results: the mortality was higher in patients with RBG more than 300 mg/dl (68.4 %, (10.5 % of the patients had ranged from 250 ─ < 300 mg/dl, and the patients had ranged from 200 ─ < 250 mg/dl were (10.5 %. The patients had ranged from 160 ─ < 200 mg/dl were (5.3 and there were (5.3 of the patients had ranged from 70 ─ < 160mg/dl. Conclusions: The data from this study have shown that hyperglycemia on admission was associated with a worse outcome for all patients admitted with ACS.

    Data on the effect of fasting on coronary disease are rare and controversial. The aim of our study was to investigate the influence of Ramadan on the prevalence of acute coronary syndrome among chest pain patients in the emergency department of Monastir. It was a prospective study, performed in the emergency department of Fattouma Bourguiba University Hospital of Monastir, during the 3 months before, during and after Ramadan from 2012 to 2014. We included all patients with non-traumatic chest pain during the study period. Data were collected using a standardized form. The uniformity chi 2 test, ANOVA test, Kruskal-Wallis test were performed at the 5% level. Binary logistic regression model was used for multivariate analysis. The SCA prevalence was 17% a month before Ramadan, 22% during Ramadan and 28% one month after Ramadan (p = 0.007). According to the results of the multivariate analysis, the period of Ramadan is not associated with increase of risk of SCA whereas the risk doubles after Ramadan in all group (p = 0.001). In subgroups analysis, the period of R was associated with an amplification of risk in men aged more than 55 years and women older than 65 years (OR: 2.1; p = 0.020) and among subjects with hypertension (OR: 2.4, p = 0.007). Ramadan and Shawwal were not associated with an increase of risk among subjects without CVX risk factor. We have demonstrated that the risk of SCA has increased in Ramadan only among the elderly and patient with hypertension. The increased risk in Shawwal can be explained by the lifting of dietary restriction.

    It has been shown that cytomegalovirus (CMV) is present in coronary atherosclerotic plaques, but the clinical relevance of this presence remains to be elucidated. In this study we sought to examine CMV infection in atherosclerosis patients defined by different methods and to identify the clinical significance of CMV replication in the atherosclerotic plaques. The study included 105 consecutive patients who were admitted to our department and underwent coronary artery bypass grafting (CABG) surgical interventions. Coronary atherosclerotic specimens as well as 53 specimens from the mamillary artery of these same patients were analyzed. Enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) methods were used for evaluations. The CMV PCR test result was positive for 28 (26.7%) of patients with coronary artery atherosclerosis. After adjusting for other risk factors, coronary artery disease patients with a history of acute coronary syndrome were more likely to be positive for CMV PCR test (P=0.027; odds ratio: 4.2; 95% CI: 1.18-15.0). They were also more likely to have a positive family history for cardiovascular diseases (CVD). This study confirms previous evidence about the replication of CMV virus in the atherosclerotic plaques of coronary arteries and brings clinical significance to this observation by showing a higher prevalence of acute coronary syndromes in those patients with CMV-infected plaques. Our study also suggests a familial vulnerability to CMV replication in the coronary artery walls.

    The modern care of suspected and confirmed acute coronary syndrome (ACS) is informed by an extensive and evolving evidence base. This clinical practice guideline focuses on key components of management associated with improved clinical outcomes for patients with chest pain or ACS. These are presented as recommendations that have been graded on both the strength of evidence and the likely absolute benefit versus harm. Additional considerations influencing the delivery of specific therapies and management strategies are presented as practice points. This guideline provides advice on the standardised assessment and management of patients with suspected ACS, including the implementation of clinical assessment pathways and subsequent functional and anatomical testing. It provides guidance on the: diagnosis and risk stratification of ACS; provision of acute reperfusion therapy and immediate post-fibrinolysis care for patients with ST segment elevation myocardial infarction; risk stratification informing the use of routine versus selective invasive management for patients with non-ST segment elevation ACS; administration of antithrombotic therapies in the acute setting and considerations affecting their long term use; and implementation of an individualised secondary prevention plan that includes both pharmacotherapies and cardiac rehabilitation. Changes in management as a result of the guideline: This guideline has been designed to facilitate the systematic integration of the recommendations into a standardised approach to ACS care, while also allowing for contextual adaptation of the recommendations in response to the individual's needs and preferences. The provision of ACS care should be subject to continuous monitoring, feedback and improvement of quality and patient outcomes.

    Although glucose-insulin-potassium (GIK) therapy ought to be beneficial for ischemic heart disease in general, variable outcomes in many clinical trials of GIK in acute coronary syndrome (ACS) had a controversial impact. This study was designed to examine whether "insulin resistance" is involved in ACS and to clarify other potential intrinsic compensatory mechanisms for GIK tolerance through highly statistical procedure. We compared the degree of insulin resistance during ACS attack and remission phase after treatment in individual patients (n = 104). During ACS, homeostasis model assessment of insulin resistance (HOMA-IR) values were significantly increased (Pcovariance structure analysis with a strong impact (β: 0.398, P = 0.015). Intriguingly, a higher incidence of myocardial infarction relative to unstable angina pectoris, as well as a longer hospitalization period were observed in patients with larger ΔK, indicating that ΔK also reflects disease severity of ACS. Insulin resistance most likely increases during ACS; however, ΔK was positively correlated with plasma glucose level, which overwhelmed insulin resistance condition. The present study with covariance structure analysis suggests that there are potential endogenous glucose-coupled potassium lowering mechanisms, other than insulin, regulating glucose metabolism during ACS.

In this context, the main risk factor in elderly patients, ie, frailty syndrome, gains special importance. The availability of tools to identify frail people is relevant for both research and clinical purposes. The purpose of this study was to investigate the correlation of a scale for assessing frailty – the Tilburg Frailty Indicator (TFI and its domains (mental and physical – with other research tools commonly used for comprehensive geriatric assessment in patients with ACS.Patients and methods: The study covered 135 people and was carried out in the cardiology ward at T Marciniak Lower Silesian Specialist Hospital in Wroclaw, Poland. The patients were admitted with ACS. ST segment elevation myocardial infarction and non-ST segment elevation myocardial infarction were defined by the presence of certain conditions in reference to the literature. The Polish adaptation of the TFI was used for the frailty syndrome assessment, which was compared to other single measures used in geriatric assessment: the Mini-Mental State Examination (MMSE, the Hospital Anxiety and Depression Scale (HADS, and Katz Index of Independence in Activities of Daily Living (ADLs.Results: The mean TFI value in the studied group amounted to 7.13±2.81 (median: 7, interquartile range: 5–9, range [0, 14]. Significant correlations were demonstrated between the values of the TFI and other scales: positive for HADS (r=0.602, P<0.001 and the reverse for MMSE (r=-0.603, P<0.001 and IADL (r=-0.462, P<0.001. Patients with a TFI score ≥5 revealed considerably higher values on HADS (P<0.001 and considerably lower values on the MMSE

    Independent predictors of death and death or myocardial infarction (MI) during initial hospitalization of patients with acute coronary syndromes (ACS) were determined using database of Russian independent ACS registry RECORD. These predictors (admission Killip class II, ST-segment elevation 1 mm, systolic blood pressure 100 mm Hg, hemoglobin <110 g/L, age 65 years, history of diabetes) were attributed equal weight (1 point) and combined in a prognostic scale for assessment of risk of inhospital death and death or MI. The scale did not include markers of necrosis, and the most time consuming component was measurement of hemoglobin. Sensitivity and specificity of risk scores for prediction of death were 78.5%. The use of GRACE score in this group of patients gave similar results. These preliminary data require confirmation on larger populations of patients with ACS.

    Full Text Available Siti-Zainora Mohd-Zulkefli, Marhanis-Salihah Omar, Adyani Md-Redzuan Faculty of Pharmacy, Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia Background: The incidence of acute coronary syndrome (ACS, one of the most common cardiovascular diseases, is high. Lipid goal attainment is one of the important factors to reduce the risk of recurrent heart attack. Identification of factors influencing lipid goal attainment such as age, female, race, underlying comorbidities, intensity of lipid-lowering therapy, patients’ knowledge, and patients’ belief about medicine would be beneficial in achieving the lipid goal. This study is aimed to determine lipid profile attainment and prescribing pattern of lipid-lowering therapy as well as to identify factors influencing lipid profile attainment among ACS patients.Patients and methods: This researcher-assisted cross-sectional survey was carried out at a cardiology clinic in a tertiary hospital from March to May 2015.Results: A total of 101 ACS patients were involved in this study. The mean values for low-density lipoprotein cholesterol (LDL-C and high-density lipoprotein cholesterol levels were 2.75 (0.82 mmol/L and 1.14 (0.27 mmol/L, respectively, while the median value for triglyceride level was 2.75 (0.82 mmol/L. Only 15.8% of our participants achieved the targeted LDL-C. Simvastatin 20 mg was the most common regimen prescribed. Predictors for better LDL-C attainment were younger age (β=-0.228; P=0.032 and higher knowledge score (β=-0.255; P=0.049, while predictors for high-density lipoprotein cholesterol attainment were male (β=0.268; P=0.006, smoking (β=-0.192; P=0.045, and higher knowledge score (β=-0.195; P=0.039. Smoking (β=-0.361; P<0.0001 was the only predictor for higher triglyceride level.Conclusion: Younger age, female, lower knowledge score, and smoking status are good predictors for lipid attainment among ACS patients.

    To assess the long-term cost-effectiveness of 12 months treatment of prasugrel compared to clopidogrel in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) in the Spanish health care system. A Markov state transition model was developed to estimate health outcomes, quality adjusted life years (QALYs), life years (LY), and costs over patients' lifetimes. Clinical inputs were based on an analysis of the TRITON-TIMI 38 clinical trial. Hospital readmissions captured during the trial in a sub-study of patients from eight countries (and subsequent re-hospitalisations modelled to accrue beyond the time horizon of the trial), were assigned to Spanish diagnosis-related group payment schedules to estimate hospitalisation costs. Mean total treatment costs were ?11,427 and ?10,910 for prasugrel and clopidogrel respectively. The mean cost of the study drug was ?538 higher for prasugrel vs. clopidogrel, but rehospitalisation costs at 12 months were ?79 lower for prasugrel due to reduced rates of revascularisation. Hospitalisation costs beyond 12 months were higher with prasugrel by ?55, due to longer life expectancy (+0.071 LY and +0.054 QALYs) associated with the decreased nonfatal myocardial infarction rate in the prasugrel group. The incremental cost per life year and QALY gained with prasugrel was ?7,198, and ?9,489, respectively. Considering a willingness-to-pay threshold of ?30,000/QALY gained in the Spanish setting, prasugrel represents a cost-effective option in comparison with clopidogrel among patients with ACS undergoing PCI.

    Full Text Available Background. An inverse relationship between cardiovascular risk and levels of vitamin D and omega-3 index may exist. Objectives. To evaluate the prognostic utility of serum 25-hydroxyvitamin D [25(OHD] in 871 patients with suspected acute coronary syndrome (ACS and to assess the seasonal correlation between 25(OHD and the omega-3 index in 456 ACS patients from southwestern Norway. Results. In the univariate analysis the hazard ratio (HR at 2-year follow-up for all-cause mortality in the highest as compared to the lowest quartile of 25(OHD in the total population was 0.61 (95% confidence interval (CI, 0.37–1.00, P=0.050. At 7-year follow-up, the corresponding HR for all-cause mortality was 0.66 (95% CI, 0.49–0.90, P=0.008, and for females alone 0.51 (95% CI, 0.32–0.83, P=0.006. Quartile survival did not differ in the multivariable analysis, whereas 25(OHD < 40 nM (<16 ng/mL was found to be independently related to mortality. Seasonal differences in 25(OHD, but not for the omega-3 index, were noted, and the two biomarkers were positively correlated, especially during winter-spring; Pearson’s correlation coefficient was 0.358, P<0.001. Conclusion. Vitamin D levels are related to survival, especially in females, and correlate with the omega-3 index.

    Few data are so far available on the relation between increased glucose values and insulin resistance and mortality at short-term in patients with acute heart failure (AHF). The present investigation, performed in 409 consecutive patients with AHF complicating acute coronary syndrome (ACS), was aimed at assessing the prognostic role of admission glycaemia and acute insulin resistance (as indicated by the Homeostatic Model Assessment - HOMA index) for death during Intensive Cardiac Care (ICCU) stay. Admission glucose tertiles were considered. In our series, diabetic patients accounted for the 33%. Patients in the third glucose tertiles exhibited the lowest LVEF (both on admission and at discharge), a higher use of mechanical ventilation, intra-aortic balloon pump and inotropic drugs and the highest in-ICCU mortality rate. In the overall population, hyperglycaemic patients (both diabetic and non diabetic) were 227 (227/409, 55.5%). Admission glycaemia was an independent predictor of in-ICCU mortality, together with admission LVEF and eGFR, while acute insulin resistance (as indicated by HOMA-index) was not associated with early death. The presence of admission hyperglycaemia in non-diabetic patients was independently associated with in-ICCU death while hyperglycaemia in diabetic patients was not. According to our results, hyperglycaemia is a common finding in patients with ACS complicated by AHF and it is an independent predictor of early death. Non-diabetic patients with hyperglycaemia are the subgroup with the highest risk of early death.

    To examine the association between elevated leukocyte count and hospital mortality and heart failure in patients enrolled in the multinational, observational Global Registry of Acute Coronary Events (GRACE). Elevated leukocyte count is associated with adverse hospital outcomes in patients presenting with acute myocardial infarction (AMI). The association of this prognostic factor with hospital mortality and heart failure in patients with other acute coronary syndromes (ACS) is unclear. We examined the association between admission leukocyte count and hospital mortality and heart failure in 8269 patients presenting with an ACS. This association was examined separately in patients with ST-segment elevation AMI, non-ST-segment elevation AMI, and unstable angina. Leukocyte count was divided into 4 mutually exclusive groups (Q): Q1 12,000. Multiple logistic regression analysis was performed to examine the association between elevated leukocyte count and hospital events while accounting for the simultaneous effect of several potentially confounding variables. Increasing leukocyte count was significantly associated with hospital death (adjusted odds ratio [OR] 2.8, 95% CI 2.1-3.6 for Q4 compared to Q2 [normal range]) and heart failure (OR 2.7, 95% CI 2.2-3.4) for patients presenting with ACS. This association was seen in patients with ST-segment elevation AMI (OR for hospital death 3.2, 95% CI 2.1-4.7; OR for heart failure 2.4, 95% CI 1.8-3.3), non-ST-segment elevation AMI (OR for hospital death 1.9, 95% CI 1.2-3.0; OR for heart failure 1.7, 95% CI 1.1-2.5), or unstable angina (OR for hospital death 2.8, 95% CI 1.4-5.5; OR for heart failure 2.0, 95% CI 0.9-4.4). In men and women of all ages with the spectrum of ACS, initial leukocyte count is an independent predictor of hospital death and the development of heart failure.

    In the Providing Regional Observations to Study Predictors of Events in the Coronary Tree (PROSPECT) study, plaque burden, plaque composition, and minimal luminal area were associated with an increased risk of adverse cardiovascular events arising from untreated atherosclerotic lesions (vulnerable plaques) in patients with acute coronary syndromes (ACS). We sought to evaluate the utility of biomarker profiling and clinical risk factors to predict 3-year all-cause and nonculprit lesion-related major adverse cardiac events (MACEs). Of 697 patients who underwent successful percutaneous coronary intervention (PCI) for ACS, an array of 28 baseline biomarkers was analyzed. Median follow-up was 3.4 years. Beta2-microglobulin displayed the strongest predictive power of all variables assessed for all-cause and nonculprit lesion-related MACE. In a classification and regression tree analysis, patients with beta2-microglobulin >1.92 mg/L had an estimated 28.7% 3-year incidence of all-cause MACE; C-peptide 1.92 mg/L identified a cohort with a 3-year rate of 18.5%, and C-peptide PROSPECT study, beta2-microglobulin strongly predicted all-cause and nonculprit lesion-related MACE within 3 years after PCI in ACS. C-peptide and HDL provided further risk stratification to identify angiographically mild nonculprit lesions prone to future MACE. Copyright © 2015 Elsevier Inc. All rights reserved.

    Recent studies have shown fondaparinux's superiority over enoxaparin in patients with non-ST elevation acute coronary syndrome (ACS), especially in relation to bleeding reduction. The description of this finding in a Brazilian registry has not yet been documented. To compare fondaparinux versus enoxaparin in in-hospital prognosis of non-ST elevation ACS. Multicenter retrospective observational study. A total of 2,282 patients were included (335 in the fondaparinux group, and 1,947 in the enoxaparin group) between May 2010 and May 2015. Demographic, medication intake and chosen coronary treatment data were obtained. Primary outcome was mortality from all causes. Secondary outcome was combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). Comparison between the groups were done through Chi-Square test and T test. Multivariate analysis was done through logistic regression, with significance values defined as p acidente vascular cerebral e sangramentos). A comparação entre os grupos foi realizada por meio de Q-quadrado e teste-T. A análise multivariada foi realizada por regressão logística, sendo considerado significativo p < 0,05. Em relação ao tratamento, observou-se realização de intervenção coronária percutânea em 40,2% no grupo fondaparinux e 35,1% no grupo enoxaparina (p = 0,13).

    Type II diabetes and the metabolic syndrome are strong predictors of severity of occlusive coronary disease and poorer outcomes of coronary revascularization therapies. Coronary collateral growth can provide an alternative or accessory pathway of revascularization. However, collateral growth is impaired in type II diabetes and the metabolic syndrome. Although many factors necessary for collateral growth are known and many interventions have shown promising results in animal studies, not a single attempt to induce coronary collateral growth in human clinical trials has led to satisfactory results. Accordingly, the first part of this review outlines the known deleterious effects of diabetes and the metabolic syndrome on factors necessary for collateral growth, including pro-angiogenic growth factors, endothelial function, the redox state of the coronary circulation, intracellular signaling, leukocytes and bone marrow-derived progenitors cells. The second section highlights the gaps in our current knowledge of how these factors interact with the radically altered environment of the coronary circulation in diabetes and the metabolic syndrome. The interplay between these pathologies and inadequately explored areas related to the temporal regulation of collateral remodeling and the roles of the extracellular matrix, vascular cell phenotype and pro-inflammatory cytokines are emphasized with implications to development of efficient therapies.

    Constipation is a common health problem that adversely affects quality of life and the prognosis of hospitalized patients with acute coronary syndromes (ACS). The purpose of this study was to develop and test the sweet potato/footbath/acupressure massage (SFA) intervention as a safe treatment for prevention of constipation and to increase satisfaction with bowel emptying in hospitalized patients with ACS. The study was a prospective, randomized controlled trial with a sample of 93 patients (SFA group, n = 44; usual care group, n = 49). Patients in the SFA group received SFA intervention combined with usual care. The results showed that there were statistical differences between the two groups in terms of (1) the incidence of constipation; (2) the use of laxatives and enemas; (3) patients' subjective satisfaction with their bowel emptying during hospitalization; and (4) sensation of incomplete evacuation and anorectal obstruction/blockade. The SFA intervention was more effective, economical, and practical than usual care alone in managing constipation and satisfaction with defecation in patients hospitalized with ACS.

    Improvement in risk stratification of patients with non-ST-segment elevation acute coronary syndrome (ACS) is a gateway to a more judicious treatment. This study examines whether the routine determination of left ventricular ejection fraction (EF) adds significant prognostic information to currently recommended stratifiers. Several predictors of inhospital mortality were prospectively characterized in a registry study of 1104 consecutive patients, for whom an EF was determined, who were admitted for an ACS. Multiple regression models were constructed using currently recommended clinical, electrocardiographic, and blood marker stratifiers, and values of EF were incorporated into the models. Age, ST-segment shifts, elevation of cardiac markers, and the Thrombolysis in Myocardial Infarction (TIMI) risk score all predicted mortality (P model improved the prediction of mortality (C statistic 0.73 vs 0.67). The odds of death increased by a factor of 1.042 for each 1% decrement in EF. By receiver operating curves, an EF cutoff of 48% provided the best predictive value. Mortality rates were 3.3 times higher within each TIMI risk score stratum in patients with an EF of 48% or lower as compared with those with higher. The TIMI risk score predicts inhospital mortality in a broad population of patients with ACS. The further consideration of EF adds significant prognostic information.

    Depression is prevalent in patients hospitalized with acute coronary syndrome (ACS). We determined whether theoretical vulnerabilities for depression (interpersonal life events, reinforcing events, cognitive distortions, Type D personality) predicted depression, or depression trajectories, post-hospitalization. We followed 375 ACS patients who completed depression scales during hospital admission and at least once during three follow-up intervals over 1 year (949 observations). Questionnaires assessing vulnerabilities were completed at baseline. Logistic regression for panel/longitudinal data predicted depression status during follow-up. Latent class analysis determined depression trajectories. Multinomial logistic regression modeled the relationship between vulnerabilities and trajectories. Vulnerabilities predicted depression status over time in univariate and multivariate analysis, even when controlling for baseline depression. Proportions in each depression trajectory category were as follows: persistent (15%), subthreshold (37%), never depressed (48%). Vulnerabilities independently predicted each of these trajectories, with effect sizes significantly highest for the persistent depression group. Self-reported vulnerabilities - stressful life events, reduced reinforcing events, cognitive distortions, personality - measured during hospitalization can identify those at risk for depression post-ACS and especially those with persistent depressive episodes. Interventions should focus on these vulnerabilities. Copyright © 2011 Elsevier Inc. All rights reserved.

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

    Depression is common after acute coronary syndrome (ACS) and has adverse effects on prognosis. There are few evidence-based interventions for treating depression in ACS. This study investigated the efficacy and safety of escitalopram in treating depressive disorders identified 2-14 weeks after a confirmed ACS episode. A total of 217 patients with DSM-IV depressive disorders (121 major and 96 minor) and ACS were randomly assigned to receive escitalopram in flexible doses of 5-20 mg/d (n = 108) or placebo (n = 109) for 24 weeks. The study was conducted from 2007 to 2013. The primary outcome measure was the Hamilton Depression Rating Scale (HDRS). Secondary outcome measures included the Montgomery-Asberg Depression Rating Scale (MADRS), Beck Depression Inventory (BDI), Clinical Global Impressions-Severity of Illness scale (CGI-S), Social and Occupational Functioning Assessment Scale (SOFAS), and World Health Organization Disability Assessment Schedule-12. Cardiovascular safety outcomes included echocardiography, electrocardiography, laboratory test, body weight, and blood pressure results. Escitalopram was superior to placebo in reducing HDRS scores (mean difference = 2.3, P = .016, effect size = 0.38). Escitalopram was also superior to placebo in decreasing depressive symptoms evaluated by the MADRS, BDI, and CGI-S and in improving SOFAS functioning level. Escitalopram was not associated with any harmful changes in cardiovascular safety measures. Dizziness was significantly more frequently reported in the escitalopram group (P = .018), but there were no significant differences in any other adverse events. These results indicate that escitalopram has clinically meaningful antidepressant effects with no evidence of reduced cardiovascular safety in depressive disorder following ACS.

    Full Text Available Background: Mortality from cardiovascular disease in the Middle East is projected to increase substantially in the coming decades. The prevalence of metabolic syndrome (MS in acute coronary syndrome (ACS continues to raise interest, but data from the Middle East is limited, especially in non-diabetic patients. This study was conducted to ascertain the prevalence of MS and frequency of its components, individually and in combination, in a male population presenting with ACS, but without a previous diagnosis of diabetes mellitus (DM. Methods: This is a prospective study of 467 consecutive male patients hospitalized for ACS. They were categorized according to the specific criteria stated in the latest joint statement for the global definition of MS. Results: The mean age was (49.7±10.7 years. Of the 467 patients, 324 (69.4% fulfilled the criteria for MS. ST-Elevation Myocardial Infarction (STEMI was identified in 178 patients (54.9%, and non-ST elevation ACS (NSTE-ACS in 146 patients (45.1%. These proportions were not significantly different from those without MS (STEMI 51.7% vs. NSTE-ACS 48.3%, respectively. However, patients with MS were older (50.6±10 vs. 47.9±11 years; p=0.012, and more than half of those with MS were above 50 years. The most common abnormal metabolic components were reduced high-density lipoprotein cholesterol (HDL-c; 94.1%, elevated fasting blood glucose (FBG; 89.8%, and elevated triglycerides (81.8%, followed by increased waist circumference (61.7% and raised blood pressure (40.4%. The majority of patients with MS had three or more metabolic components (326 patients, 69.4%, and 102 (21.8% had two components, but only 37 (8.4% had a single component. Conclusions: In ACS patients, without previous history of DM, MS is highly prevalent. Reduced HDL, elevated FBG and triglycerides were the most frequent metabolic components. The majority had multiple components. These findings raise alarm and show that drug therapy alone may

    Methods to measure or quantify equity in health care remain scarce, if not difficult to interpret. A novel method to measure health equity is presented, applied to gender health equity, and illustrated with an example of timing of angiography in patients following a hospital admission for an acute coronary syndrome. Linked administrative hospital discharge and survey data was used to identify a retrospective cohort of patients hospitalized with Acute Coronary Syndrome (ACS) between 2002 and 2008 who also responded to the Canadian Community Health Survey (CCHS), was analyzed using decision trees to determine whether gender impacted the delay to angiography following an ACS. Defining a delay to angiography as 1 day or more, resulted in a non-significant difference in an equity score of 0.14 for women and 0.12 for men, where 0 and 1 represents perfect equity and inequity respectively. Using 2 and 3 day delays as a secondary outcome resulted in women and men producing scores of 0.19 and 0.17 for a 2 day delay and 0.22 and 0.23 for a 3 day delay. A technique developed expressly for measuring equity suggests that men and women in Ontario receive equitable care in access to angiography with respect to timeliness following an ACS.

    Hospital performance models in acute myocardial infarction (AMI) are useful to assess patient management. While models are available for individual countries, mainly US, cross-European performance models are lacking. Thus, we aimed to develop a system to benchmark European hospitals in AMI and percutaneous coronary intervention (PCI), based on predicted in-hospital mortality. We used the EURopean HOspital Benchmarking by Outcomes in ACS Processes (EURHOBOP) cohort to develop the models, which included 11,631 AMI patients and 8276 acute coronary syndrome (ACS) patients who underwent PCI. Models were validated with a cohort of 55,955 European ACS patients. Multilevel logistic regression was used to predict in-hospital mortality in European hospitals for AMI and PCI. Administrative and clinical models were constructed with patient- and hospital-level covariates, as well as hospital- and country-based random effects. Internal cross-validation and external validation showed good discrimination at the patient level and good calibration at the hospital level, based on the C-index (0.736-0.819) and the concordance correlation coefficient (55.4%-80.3%). Mortality ratios (MRs) showed excellent concordance between administrative and clinical models (97.5% for AMI and 91.6% for PCI). Exclusion of transfers and hospital stays ≤1day did not affect in-hospital mortality prediction in sensitivity analyses, as shown by MR concordance (80.9%-85.4%). Models were used to develop a benchmarking system to compare in-hospital mortality rates of European hospitals with similar characteristics. The developed system, based on the EURHOBOP models, is a simple and reliable tool to compare in-hospital mortality rates between European hospitals in AMI and PCI.

    Depression is associated with increased risk of cardiovascular morbidity and mortality in coronary heart disease. Numerous conventional and complementary therapies may address depression. Few involving spirituality have been tested. The aim of this study was to compare the effects of a nondenominational spiritual retreat, Medicine for the Earth (MFTE), on depression and other measures of well-being six- to 18-months post acute coronary syndrome (ACS). A randomized controlled pilot study of MFTE, Lifestyle Change Program (LCP), or usual cardiac care (control) was conducted in Southeastern Michigan. ACS patients were recruited via local and national advertising (n = 58 enrolled, 41 completed). The four-day MFTE intervention included guided imagery, meditation, drumming, journal writing, and nature-based activities. The four-day LCP included nutrition education, exercise, and stress management. Both retreat groups received follow-up phone coaching biweekly for three months. Validated self-report scales of depression, spiritual well-being, perceived stress, and hope were collected at baseline, immediately post-retreat, and at three and six months. Depression was not significantly different among groups (P = .21). However, the MFTE group had the highest depression scores at baseline and had significantly lower scores at all postintervention time points (P ≤ .002). Hope significantly improved among MFTE participants, an effect that persisted at three- and six-month follow-up (P = .014). Although several measures showed improvement in all groups by six months, the MFTE group had immediate improvement post-retreat, which was maintained. This pilot study shows that a nondenominational spiritual retreat, MFTE, can be used to increase hope while reducing depression in patients with ACS. Copyright © 2011 Elsevier Inc.
