ST-Segment Elevated Acute Myocardial Infarction: Changing Profile Over Last 24 Years.

BACKGROUND: Coronary artery disease (CAD) is rising in epidemic proportions with India not being an exception. CAD in Indian scenario has its onset at a younger age with multitude of risk factors. OBJECTIVE: This study was carried out to obtain complete information about demographic profile, risk factors, clinical scenario, therapeutic modalities, natural course, outcome and changing profile of acute ST-segment elevated myocardial infarction (STEMI) patients. METHODS: This cross-sectional study was conducted in 45,122 acute STEMI patients admitted 1st March 1990 to 1st March 2014. A predefined performa was completed in every patient with detailed clinical history, physical examination, laboratory and investigation parameters, therapeutic interventions and inhospital outcome. RESULTS: Our population cohort presented with STEMI at age of 56.34±11.88 years with 82.48% male. Urban residency (64.35%), lower level of education (61.03%), middle and low socioeconomic status (81.01%), unemployment (56.47%), lack of exercise (78.80%) and poor dietary pattern including low intake of fruits and vegetables (58.80%) were pivotal players. Smoking was prevalent in 48.80% cases, with overweight and obesity (51.11%), diabetes mellitus (27.34%), hypertension (38.85%), hyperlipidemia (28.15%), alcoholism (28.80%) and family history (16.66%). Our population had mildly elevated LDL (101.4±33.38 mg/dl), low HDL (36.6±10.7 mg.dl) and high TC/HDL ratio (4.05±1.36). Majority harbored (52.06%) two or more risk factors, while in 16.60% no conventional risk factors were identified. Anterior wall STEMI (56.78%) far exceeded the inferior wall (37.55%). Less than half (47.77%) presented within the window period of 12 hours while only 0.8% of patients availed the golden period of 1 hour. 50.27% presented in Killip Class II or beyond. Angiography revealed single vessel disease (46.76%) with LAD involvement being most common (58.85%). Thrombolytic therapy was provided in 38.95% and primary PCI in 2.1%. Complications in the form of CHF (34.7%), cardiogenic shock (8.65%), reinfarction (6.5%), arrhythmia (59.2%) and mortality (10.57%) were seen. Mortality decreased from 13.9% (from 1990-2000) to 8.8% (2000-2014). CONCLUSIONS: With recent increased use of ß-blocker, ACEI/ARB, aldosterone antagonist and reperfusion strategy, we have brought down the mortality to lower level.

Clinical characteristics and 30-day outcomes in patients with acute decompensated heart failure: Results from Indian College of Cardiology National Heart Failure Registry (ICCNHFR).

BACKGROUND: Acute decompensated heart failure (ADHF) is a challenging medical emergency with high mortality and its prevalence is increasing in India. There is paucity of data on ADHF in the country. METHODS: Indian College of Cardiology National Heart Failure Registry (ICCNHFR) is an on-going observational registry on ADHF contributed by 22 hospitals across India; and we present the in-hospital and 30-day outcomes of ADHF patients enrolled from August 2018 to July 2019. Major objective included capturing demographics, comorbid conditions, aetiology, prescription patterns and assessing clinical outcomes. RESULTS: Of 5269 patients (mean age: 61.90 ± 13.85 years) enrolled in this study, males were predominant (67.09%). Mean duration of hospitalization was 5.74 ± 4.74 days. Ischemic heart disease was the most common (75.44%) aetiology. Abnormal electrocardiogram readings were found in most patients (89.86%). LVEF of ˂40% was found in 68.29% of patients. In-hospital mortality rates were 6.98%. The 30-day cumulative mortality was 12.35% and 30-day rehospitalization rate was 7.98%. At discharge, all guideline-based medical therapy (GDMT) were prescribed only to 24.99% of patients and 23.72% adhered to the prescription until 30 days. Older age, high serum creatinine levels and poor LVEF contributed to high mortality and rehospitalization. CONCLUSION: Patients with ADHF were younger and predominantly males. Usage of GDMT in ADHF patients was low (24.99%) and the in-hospital mortality was high. Older age, high serum creatinine levels, poor LVEF contributed for 30-day mortality and rehospitalization. This data on ADHF, could help in developing strategies to improve outcomes for HF patients in India.

Cardiovascular manifestations of people living with HIV/AIDS: Report from a hot spot in eastern India.

OBJECTIVE: To study the profile and characteristics of cardiovascular abnormalities among patients living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) at a tertiary care hospital in India. The association of cardiovascular abnormalities with the CD4 count and disease stages, according to the World Health Organization (WHO) classification, was also analyzed. METHODS: A total of 200 patients with HIV/AIDS were compared with 50 healthy controls. All patients underwent blood investigations, chest X-ray, electrocardiography, and echocardiography. RESULTS: The mean age of the patients was 38.66 ± 9.22 years, with a male-to-female ratio of 3.25:1. Echocardiographic abnormalities were found in 52% of the patients and 12% of the controls, with the most common abnormality being left ventricular diastolic dysfunction. Echocardiographic abnormalities were markedly more common in patients with a CD4 count of <200/µL. The advanced stage of the disease, according to the WHO classification, was also associated with an increased incidence of echocardiographic abnormalities. CONCLUSIONS: Cardiovascular abnormalities in the form of electrocardiogram and ECHO findings were present in 54.5% and 52% of patients, respectively. Echocardiographic findings showed significant correlation with CD4 count and WHO disease stage.

Current perspectives on statins.

As the epidemic of coronary artery disease rages on round the globe, research is always on to find suitable drugs to reverse the trend. While aspirin, beta-blockers and ACE inhibitors have been shown to reduce coronary mortality and morbidity, statins are rapidly coming to fore as another important cog in the wheel of primary and secondary prevention of coronary artery disease. Newer trial like Heart Protection Study suggests benefit of statin for high risk individuals, irrespective of initial serum cholesterol concentrations. This may be of great relevance in the Indian context taking into consideration the vast majority of coronary artery disease patients having normal to mildly elevated serum cholesterol in contrast to their western counterparts.
