Background & Aims: Acute coronary syndrome is one of the leading causes of morbidity and mortality in the world and platelet hyperactivity with local platelet activation plays a crucial role in its genesis. As there is discrepancy regarding the significance of deranged platelet parameters, we aimed to study the role of platelet volume indices in the spectrum of coronary artery syndrome and to correlate them clinically. Study Design: The study was conducted by collecting the data of patients with Myocardial infarction from the Cardiac care unit registry along with their clinical history and investigations. Stable coronary artery cases were collected from the Catheterization Lab and compared with Age and Sex matched controls. All CBCs of the above groups were processed by a 5-part counter and the data generated was transferred to a master chart for statistical analysis. Place and Duration of study: The study was conducted in the Central Laboratory & Department of Pathology at D.Y. Patil Hospital, Navi Mumbai, India in collaboration with the Cardiac Care Unit and Catheterisation Lab of the hospital for a period of two years. Methods: A total of 122 cases were studied and grouped into 5 groups according to presentation and the platelet volume indices of these were compared with 38 matched controls and statistically analysed. Results: Mean Platelet Volume and Platelet Distribution Width of patients with ST elevation Myocardial Infarction (STEMI) and Non ST elevation Myocardial Infarction(NSTEMI) were increased marginally in number when compared to Stable Coronary Artery Disease(SCAD) and Control group, however this was not statistically significant. Platelet Large Cell Ratio (PLCR) was significantly raised in STEMI cases only (P = 0.09), so it may prove to be a better marker for the disease (P = 0.09). Platelet counts in various groups when compared with controls gave inconsistent results i.e SCAD vs Control significantly decreased (P = 0.07) and STEMI vs Control significantly increased (P = 0.01). Conclusion: The platelet volume indices in suspected acute coronary syndrome cases showed various changes, but present data failed to be diagnostically significant. However this data may later help to characterise further relationship between Acute coronary syndrome and platelet function in subsequent studies.

Background and Aims: Acute coronary syndrome (ACS) refers to a group of clinical symptoms consistent with new onset or worsening ischemic symptoms. ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI) and unstable angina (UA) are the three types of ACS. The objectives were to study the risk factors prevalence, angiographic distribution and severity of coronary artery stenosis in ACS among patients admitted in Cardiology Department of Manmohan Cardiothoracic Vascular and Transplant Center (MCVTC). Methods: This is a restrospective study of 419 ACS patients admitted and treated in MCVTC from November 2017 to October 2018. Patients were divided into STEMI, NSTEMI and UA then analyzed for various risk factors, angiographic patterns and severity of coronary artery disease. Results: Mean age of presentation was 59.3Å}12.8 years. Majority were male 317(75.7%). Most patients had STEMI 252 (60.1%) followed by NSTEMI 98 (23.4%) and UA 69 (16.5 %). Risk factors: smoking was present in 241 (57.5%), hypertension in 212 (50.6%), diabetes in 144 (34.4%), dyslipidemia in 58 (13.8%). Single-vessel disease was present in 34.6 % patients, double- vessel disease was present in 27.44 % patients and triple vessel disease was present in 26.3 % patients, left main disease in 1.4 % patients. Normal coronaries were present in 6.4% patients and minor coronary artery disease in 3.8 % patients. Conclusions: STEMI was the most common presentation. Three quarters of ACS were male patients. Smoking was most prevalent risk factor. Single vessel involvement was the most common CAG finding in all spectrum of ACS. Diabetic patients had more multivessel disease.

Vascular calcification contributes to the pathogenesis of coronary artery disease while matrix Gla protein (MGP) was recently identified as a potent inhibitor of vascular calcification. MGP fractions, such as dephosphorylated-uncarboxylated MGP (dp-ucMGP), lack post-translational modifications and are less efficient in vascular calcification inhibition. We sought to compare dp-ucMGP levels between patients with acute coronary syndrome (ACS), stratified by ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) status. Physical examination and clinical data, along with plasma dp-ucMGP levels, were obtained from 90 consecutive ACS patients. We observed that levels of dp-ucMGP were significantly higher in patients with NSTEMI compared to STEMI patients (1063.4 ± 518.6 vs. 742.7 ± 166.6 pmol/L, p < 0.001). NSTEMI status and positive family history of cardiovascular diseases were only independent predictors of the highest tertile of dp-ucMGP levels. Among those with NSTEMI, patients at a high risk of in-hospital mortality (adjudicated by GRACE score) had significantly higher levels of dp-ucMGP compared to non-high-risk patients (1417.8 ± 956.8 vs. 984.6 ± 335.0 pmol/L, p = 0.030). Altogether, our findings suggest that higher dp-ucMGP levels likely reflect higher calcification burden in ACS patients and might aid in the identification of NSTEMI patients at increased risk of in-hospital mortality. Furthermore, observed dp-ucMGP levels might reflect differences in atherosclerotic plaque pathobiology between patients with STEMI and NSTEMI.

BACKGROUND Cardiovascular diseases are one of the leading causes of morbidity and mortality worldwide. High Ca levels and low Mg levels are associated with increased cardiovascular risk in the general population.1 The balance between Ca and Mg seems to play an important role in homeostasis since Mg is considered as physiologic antagonist of Ca.2 Hence Ca/Mg ratio was considered to study its association with acute coronary syndrome (ACS). METHODS This is a case control study conducted in Karnataka Institute of Medical Sciences, Hubli over a period of 2 years, February 2019 to December 2020. 200 cases and 150 controls were included in the study. The biochemical measurements including complete blood count (CBC), cardiac biomarkers, liver function tests, renal function tests (RFT), serum electrolytes and lipid profile were measured using standard laboratory methods. Student ‘t’ test was used to compare the data. Optimum cut-offs for diagnosis of acute myocardial infarction was calculated using receiver operating characteristics (ROC) analysis. The association among markers was established by calculating Pearson’s correlation. RESULTS Serum Ca/Mg ratio was significantly higher (p value < 0.001) in ACS when compared to control groups. It was also found that Ca/Mg ratio was significantly lower (p value < 0.001) in non-ST elevation myocardial infarction (NSTEMI) when compared to STEMI group. Serum Mg was significantly lower (p value < 0.001) in ACS group when compared to control group. Significant correlation (p value < 0.05) was found between serum Ca/Mg ratio and cardiac markers (CKMB, Troponin-I). ROC analysis of Ca/Mg (4.19) ratios showed optimum cut-offs in diagnosis of AMI. CONCLUSIONS Serum Ca/Mg could be useful adjuvant marker in diagnosis of AMI. The ratio is higher in ST-segment elevation myocardial infarction when compared to non-STsegment myocardial infarction, which could be due to greater decrease in Mg levels when compared Ca in ACS.

The coronary care unit by Santa Izabel Hospital (Salvador, Bahia, Brazil) made a comparison of admitted patients with coronary disease cases admitted between two equivalent periods ranging from April through July in 2019 and 2020. There was a striking reduction in 2020 of cases of ST-elevation myocardial infarction (39%); non-ST elevation myocardial infarction (19%); and unstable angina pectoris (21%). This occurred in parallel with what happened in many parts of the world and hampered offering the best treatment strategy to these patients with an acute coronary syndrome such as invasive stratification and myocardial revascularization.

Background: Early identification and diagnosis are critical in the management of patients with acute coronary syndrome (ACS) since time-dependent therapies reduce patient mortality and morbidity. Objective: The aims of this study were to describe differences in presenting symptoms by individual ACS diagnoses and determine the prognostic value of both signs (electrocardiographic evidence of ischemia) and symptoms for an ACS diagnosis. Method: Patients > 21 years old, with any ECG ischemic changes (ST-elevation, ST-depression, T-wave inversion), elevated serum troponin, and ACS symptoms presenting to one of five emergency departments (ED) were eligible for the study. Patients completed the ACS Symptom Checklist, a validated 13-item instrument that measures cardiac symptoms (typical and atypical). Pearson Chi-square tests were used for bivariate analyses and logistic regression was used for multivariate modeling. Results: A total of 1,031 patients (mean age 60 + 14, 62% male, 70% White) were enrolled; 450 (43.7%) were diagnosed with ACS. One hundred eleven (11%) had ST-elevation myocardial infarction (STEMI), 236 (23%) had non-ST elevation myocardial infarction (NSTEMI), 103 (10%) had unstable angina (UA), and 581 (56%) were ruled-out for ACS. Patients with STEMI were more likely to report chest pain, diaphoresis, and higher symptom distress (p<0.05) at presentation than those without. Patients with NSTEMI were more likely to report arm pain and patients with UA were more likely to report lightheadedness (p<0.05). The presence of any chest symptoms (OR 2.24; 95% CI 1.27-3.97), higher symptom distress (OR 1.07; 95% CI 1.0-1.15), and a lower number of symptoms (OR 0.92; 95% CI 0.86-0.98) were independent predictors of an ACS diagnosis (p<0.05). The strongest predictor of an ACS diagnosis was the presence of ECG ischemic changes (OR 4.51, 95% CI 3.20-6.36) adjusting for symptoms, age, gender, heart rate, arrhythmia, and troponin levels (p<0.001). Conclusion: ECG signs of ischemia combined with specific symptom characteristics may enhance timely triage and detection of ACS in the ED. Predictive models that incorporate presenting signs and symptoms should be explored for this vulnerable population.
