Study of the Risk Factors for Coronary Artery Disease and their Correlation with Thyroid Hormone Profile amongst Women with ST Segment Elevation in Acute Myocardial Infarction

Abstract

Background: Thyroid hormone has a major role in the cardiovascular function and cardiac hemodynamics as well as to maintain the cardiovascular homeostasis. The present study was planned to assess risk factors for coronary artery disease and their correlation with thyroid hormone profile amongst women with ST segment elevation in acute myocardial infraction. Material and Methods: A total number of 78 females having ST elevation myocardial infarction diagnosed through detailed clinical history and ECG evaluations were included after they satisfy the eligibility criteria. Patients were subsequently evaluated for presence of risk factors of ischemic heart disease such age, marital status, parity, and menopause, use of oral contraceptives, family history, obesity, diabetes mellitus, hypertension, hypercholesterolemia and hypertriglyceridemia. Their thyroid hormone profiles (T3, T4, TSH) were done and were correlated with risk factors for ischemic heart disease. Results: A total 78 patient included in the study most of the study population belongs to the age group of 40 to 50 years (43.6 %). Hypertension was the most common clinical features amongst study population (59%) followed by Diabetes (50%). Most of the study population had Normal Thyroid status (57.69%) followed by Hypothyroidism (25.64%) and Hyperthyroidism (16.67%) and SERUM TSH is the most sensitive test for evaluation. Diabetes Mellitus was statistically significant risk factor (p valueConclusion: Patients with coronary artery disease especially in the presence of other risk factors should be screened for thyroid dysfunction specially diabetes. We recommend tests for thyroid disorders in acute coronary syndrome can give predictor for risk of morbidity and mortality in those subjects.
