Background. The association between subclinical thyroid dysfunction (defined by no symptoms or clinical features of hypothyroidism but biochemically TSH level in the range of above 5 miu/ml but below 10 miu/ml with normal FT4 level) and Acute Coronary Syndrome (ACS) is not known so far. This study was done to calculate the prevalence of subclinical thyroid dysfunction in patients with ACS. Methods. A retrospective chart review of 1100 consecutive patients was done who presented to Emergency Department with symptoms suggestive of ACS and admitted. They were later classified in 3 categories that includes Acute ST Elevated Myocardial Infarction (STEMI), Unstable Angina (UA), and Acute Non-ST Elevated Myocardial Infarction (NSTEMI). Thyroid function test (FT4, TSH) and antithyroid peroxidase (TPO) were done and evaluated properly. Results. Of 1100 consecutive patients 168 (15.27%) patients had the biochemical features of subclinical thyroid dysfunction. These 168 patients include 60 STEMI, 66 NSTEMI, and 42 Unstable Angina patients. There were no statistically significant differences in terms of left ventricular ejection fraction (LVEF) and catheterisation results considering thyroid dysfunction. Conclusions. Subclinical thyroid dysfunction is quite prevalent in ACS patients. There are no significant associations between STEMI, Unstable Angina, or NSTEMI patients in terms of thyroid dysfunction neither in single vessel versus multivessel disease involvement. The causative role and outcomes of treatment are still uncertain and need further follow-up.

Objective.More recently, evidence showed that the novel anti-inflammatory cytokine interleukin- (IL-) 37 was expressed in the foam-like cells of atherosclerotic coronary and carotid artery plaques, suggesting that IL-37 is involved in atherosclerosis-related diseases. However, the plasma levels of IL-37 in patients with acute coronary syndrome (ACS, including unstable angina pectoris and acute myocardial infarction) have yet to be investigated.Methods.Plasma IL-37, IL-18, and IL-18BP levels were measured in 50 patients with stable angina pectoris (SAP), 75 patients with unstable angina pectoris (UAP), 67 patients with acute myocardial infarction (AMI), and 65 control patients.Results.The plasma IL-37, IL-18, and IL-18BP levels were significantly increased in ACS patients compared to SAP and control patients. A correlation analysis showed that the plasma biomarker levels were positively correlated with each other and with the levels of C-reactive protein (CRP),N-terminal probrain natriuretic peptide (NT-proBNP), and left ventricular end-diastolic dimension (LVEDD) but negatively correlated with left ventricular ejection fraction (LVEF). Furthermore, the plasma IL-37, IL-18, and IL-18BP had no correlation with the severity of the coronary artery stenosis.Conclusions.The results indicate that the plasma IL-37 levels are associated with the onset of ACS.

Background: The presence of different risk groups among patients with the non–ST-elevation acute coronary syndrome indicates the need for new tools to establish early diagnoses and prognostic stratifications. The role of prolonged corrected QT (QTc) intervals in myocardial ischemia has yet to be thoroughly assessed. The purpose of our study was to assess the significance of QTc prolongations during acute non–ST-segment elevation myocardial infarction (NSTEMI) or unstable angina. Methods: The QTc interval was measured in 205 patients admitted with NSTEMI or unstable angina to the Coronary Care Unit of Fatemeh Zahra Hospital between 2014 and 2015. On that basis, the patients were divided into those with normal (<440 ms) and the ones with prolonged (≥440 ms) QTc intervals. Echocardiography and coronary angiography were performed within 48 to 72 hours after hospitalization. A logistic regression model was applied to assess the predictors of left ventricular systolic dysfunction. Results: The mean age of the patients was 58.21±10.72 years, and men comprised 51% of the participants. Overall, a QTc interval prolongation of ≥440 ms was present in 45 subjects (21.95% of the patients), which was significantly associated with a previous myocardial infarction (MI) (P=0.024), a minimum ST depression of 1 mm in the inferior leads (P=0.006), and a maximum left ventricular ejection fraction of 35% (P=0.018). Furthermore, among the different electrocardiographic variables, only a prolonged QTc interval (OR=0.275, 95% CI=0.078–0.976; and P=0.046) was inversely associated with the left ventricular systolic function. Conclusion: Our study showed that prolonged QTc intervals can be used as a useful risk marker for identifying high-risk patients with the acute coronary syndrome.

Introduction: Acute coronary syndrome (ACS) encompasses a variety of coronary artery disorders involving myocardial infarction with ST-segment-elevation (STEMI), unstable angina (UA), and myocardial infarction with non-ST elevation (NSTEMI). Hypothesis: To gain insight into the epidemiology, evaluation, in-hospital treatment, and commitment to current management guidance of ACS for patients admitted to a tertiary care hospital in a developing country. Methods: We performed a retrospective observational study of 50 consecutive patients presenting with ACS between October 2019 and December 2019, and followed for in-hospital mortality at a tertiary care general medical unit. We collected and analysed patient reports on presentation, treatment, in-hospital mortality, and major adverse cardiovascular events (MACE). Results: Patients diagnosed with ACS had a mean (SD) age of 59.3 (13.1) years, and were predominantly men (58%). Alcohol and drug consumption, smoking, and morbid obesity were significantly associated with STEMI (P < 0.05). Discharge diagnoses included STEMI (40%), NSTEMI, and unstable angina. Mean (SD) duration of hospital stay was 5.5 (5.8) days. Left ventricular ejection fraction (LVEF) was below 40% in 28% of patients, with a mean (SD) LVEF of 46.0 (15.3) ml. Median time (interquartile range) from the onset of pain to hospital admission was 80 (423) minutes for STEMI and 138 (480) minutes for NSTEMI (P > 0.05). About 72% of patients were admitted to the cardiac intensive care unit, and 34% of STEMI patients received a fibrinolytic. All patients received anti-platelet drugs. MACE were identified in 16.3% of STEMI patients and 10.6% of NSTEMI patients. Body mass index, history of cardiac disease, longer hospital duration, diabetes, and hypertension were significant predictors of in-hospital MACE. All patients were discharged and alive at the study end. All patients received standard of care treatment after discharge. Conclusions: Delays in the delivery and application of thrombolytic are coronary therapy require attention in developing countries to improve the care of patients with ACS.

Aim. To assess the relationship of abdominal obesity with left ventricular systolic function and to predict outcomes in patients with MI within 10 years.Methods. 581 medical records of patients enrolled in the Acute coronary Syndrome Registry between 2008 and 2010 were retrospectively reviewed for the period of 10 years. The following clinical endpoints were collected: all-cause mortality, cardiovascular mortality, recurrent myocardial infarction, stroke, hospitalization due to unstable angina and decompensated heart failure. Baseline left ventricular ejection fraction (LVEF) and the presence of abdominal obesity measured as waist-to-hip ratio were collected in all patients.Results. Abdominal obesity was found in 392 (67.4%) patients admitted with MI. The presence of abdominal obesity did not affect main outcomes within 10 years after the indexed event. Cardiovascular mortality was the lowest among patients with abdominal obesity., an association between abdominal obesity and low cardiovascular mortality was found in patients with intermediate LVEF using the risk stratification data based on the severity of systolic dysfunction at discharge. The highest rate of recurrent hospitalization due to unstable angina was found in patients with abdominal obesity and intermediate LVEF.Conclusion. The prevalence of abdominal obesity in MI patients was high (67%). Abdominal obesity appeared to confer protective effects on the 10-year clinical outcomes in patients with low and intermediate LVEF based on all-cause and cardiovascular mortality. The waist-to-hip ratio were significant in the generation of 10-year allcause and cardiovascular disease mortality prediction models in patients with MI.

Abstract Background Coronary artery ectasia (CAE) is a rare anomaly that can present at any age. Predisposing risk factors include Kawasaki disease in a younger population and atherosclerosis in the older generation. We present a unique case of the management of a young woman diagnosed with multivessel CAE with aneurysmal changes in the setting of acute coronary syndrome and subsequently during pregnancy. Case summary A 23-year-old woman presented with acute onset chest pain. Electrocardiogram revealed no ischaemic changes; however, troponin I peaked at 16 ng/mL (reference range 0–0.04 ng/mL). Echocardiogram showed apical dyskinesis with preserved left ventricular ejection fraction. Coronary angiography showed multivessel CAE along with significant thrombus burden in an ectatic lesion of the left anterior descending artery. Since the patient was haemodynamically stable, conservative management with dual antiplatelet therapy and anticoagulation was started. On follow-up, coronary computed tomographic angiogram illustrated resolution of the coronary thrombi and echocardiogram showed improvement to the apical dyskinesis. It was presumed that Kawasaki disease was the most likely aetiology of her disease. Subsequently the patient reported that, contrary to medical advice, she was pregnant, adding another layer of complexity to her case. Discussion Coronary artery ectasia can be discovered as an incidental finding or can present with an acute coronary syndrome. Management is challenging in the absence of randomized trials and large-scale data. Treatment options include medications, percutaneous intervention, and surgical revascularization. Close surveillance is required in these patients to assess progression of disease. Here we discuss treatment options during acute coronary syndrome and pregnancy.

Reliable Marker

Abstract Background and purpose. Cardiac troponin I (cTnI) is a reliable marker to diagnose acute myocardial infarction, but the pathophysiological explanation for the increase in cTnI levels in patients with acute ischemic stroke (IS) remains unknown. To overcome this question, we aimed to compare serum cTnI levels in acute coronary syndrome (ACS) concomitant with and without stroke. By doing like this, we thought that we could demonstrate the effect of stroke on TrpI level. Methods. Serum cTnI levels of 41 patients having ACS with acute IS during hospitalization were compared with 97 control patients having only ACS. Cranial CT was performed to evaluate the lesions. The severity of IS was evaluated objectively by national institutes of health stroke scale. Results. cTnI levels were found to be similar in both groups. Presence of diabetes mellitus, coronary artery disease and previous myocardial infarction were more frequent in patients with acute IS. The cTnI levels in the patients with the cranial lesion in the anterior circulation was higher (p = 0.039). Presence of acute IS, cTnI level higher than 20 ng/mL and left ventricular ejection fraction < 40% were found to be independent risk factors for mortality (p < 0.05). Conclusions. We found that abnormal troponin levels were more likely to be due to cardiac causes than cerebral ones in this first study evaluating the cTnI levels in patients with ACS concomitant with acute IS. The severity of IS, lesion location in the anterior circulation and higher troponin levels were associated with mortality.

Background: In the diagnosis of acute coronary syndrome, cardiac troponin I is highly reliable and widely available biomarker. Serum level of cardiac troponin I is related to amount of myocardial damage and also closely relates to infarct size. Our aim of the study is to find out the relationship between cardiac troponin I and left ventricular systolic function after acute coronary syndrome. Methods: Total of 132 acute coronary syndrome patients were included in this study after admission in coronary care unit of Sir Salimullah Medical College, Mitford Hospital. Troponin I level was measured at admission and left ventricular ejection fraction (LVEF) was measured by echocardiography between 12-48 hours of onset of chest pain. Results: There was negative correlation between Troponin I at 12 to 48 hours of chest pain with LVEF in these study patients. With a cutoff value of troponin I e”6.8 ng/ml in STEMI patients there is a significant negative relation between 12 to 48 hrs troponin I and LVEF (p<0.001). Sensitivity of troponin I e” 6.8 ng/ml between 12 to 48 hours of chest pain in predicting LVEF <50% in STEMI was 93.75% and specificity was 77.78%. In NSTEMI sensitivity of troponin I e” 4.5 ng/ml between 12 to 48 hours of chest pain in predicting LVEF <50% was 65% and specificity was 54.05%. Conclusion: Serum troponin I level had a strong negative correlation with left ventricular ejection fraction after acute coronary syndrome and hence can be used to predict the LVEF in this setting.
