Introduction: The myocardial infarction (MI) mortality has decreased markedly during recent decades, a decrease that has multiple causes. In spite of improvements, the incidence of acute MI has remained high and cardiovascular disease is still the leading cause of death, afflicting almost 50 % of both men and women. Patients and methods A hospital-based cross-sectional study. It was done on one year duration (July 2016 – June 2017) in the coronary care unit of National Institute of Cardiovascular Diseases and Hospital, Dhaka, Bangladesh. Study population were patients attending at hospital having Non ST-elevation MI screened out by clinical examination and electro-cardiography (ECG) and biochemical marker (S. Troponin I). Considering the inclusion and exclusion criteria a total number of 115 patients presented with NSTEMI were included in the study Results: The 115 Non ST Elevated patients were included in the study comprising 50 women and 65 men. The study population consisted of 51 patients (16 women, 35 men) aged under 35 years and 64 patients (34 women, 30 men) aged 50 years or older. The mean age of NSTEMI in study population is 52.45 years and the mean age of women in the study is 55.70 years and the mean age of men in the study is 49.49 years. Conclusions: In the present study men represent a large population of patients with NSTEMI than women. Smoking is the most alarming risk factors in young male while diabetes and hypertension in young female. There are substantial differences in baseline characteristics between a male and a female population with NSTEMI. So that definite measures can be formulated to the patients properly of that gender specific group.
