Background Thyroid dysfunction and associated factors like age, sex, diabetes mellitus, hypertension, smoking, family history of coronary artery disease and dyslipidemia contributes the risk for acute coronary syndrome. Objective To find out the prevalence of thyroid dysfunction and associated risk factors among acute coronary syndrome patients at this tertiary care hospital in eastern Nepal. Method A descriptive cross-sectional study was carried out prospectively among acute coronary syndrome patients at a tertiary care Hospital. Diagnosis of acute coronary syndrome was made based on the medical history, Electrocardiogram abnormalities, and cardiac markers. Thyroid function test and estimation of other blood parameters were done in the blood of the patients. Other relevant information and medical history of the patients were collected by using proforma. Result Out of 186 total acute coronary syndrome patients, 127 (68.28%) were male and mean age of all patients was 60.0 13.7 years. Thyroid dysfunction was observed in 52 (27.95%) patients, out of that subclinical hypothyroidism was mostly seen in 30 (16.12%) patients followed by hypothyroidism in 13 (6.98%). The number of patients with hyperthyroidism and subclinical hyperthyroidism was 6 (3.23%) and 3 (1.62%) respectively. Associated factors like hypertension, diabetes mellitus, smoking, family history of coronary artery disease and dyslipidemia was observed in 80 (43.01%), 42 (22.58%), 83 (44.62%), 11 (5.91%) and 79 (42.47%) patients. Conclusion Acute coronary syndrome was predominantly seen in male and subclinical hypothyroidism was a major thyroid dysfunction observed among the patients. Hypertension, dyslipidemia, diabetes mellitus and smoking was found to be associated in a proportion of patients with acute coronary syndrome.
