Coronary heart disease is a group of conditions affecting the functioning of the heart or blood vessels and is one of the leading causes of death globally. Like other countries, coronary heart disease prevalence is also rising among the adults in Bangladesh. Besides conventional risk factors for coronary heart disease, genetic predisposition and some novel issues like high salt intake, arsenicosis, hypovitaminosis D and air pollution may play important role in the aetiopathogenesis of coronary heart disease in this population. Formulation of appropriate policy and more emphasis on preventive strategy may help combat coronary heart disease in Bangladesh. The main aim of this study was to find out the pattern of coronary heart disease among the patients admitted in Cardiology department of Rajshahi Medical college Hospital and to relate their socio-demographic and economic characteristics with the disease. It was a cross sectional type of descriptive study during February 2019 to July 2019. A total of 352 patients of Cardiology department considered as sample who admitted for their heart problem during the study period selected by purposive sampling. Majorities (85.8%) of the respondents were >40 years among them 74.4% were male. Most (52.0%) of the respondents were from nuclear family and smokers (65.62%). They had history of diabetes mellitus (22.4%) and lead sedentary life (11.4%). Regarding coronary heart disease 74.7% had ischemic heart disease and right coronary artery disease (66.7%). About 42.1% were hypertensive patients and 94.0% took medical treatment. Type of heart disease was found significantly associated with age group of the respondents (p<0.01), smoking habit (p<0.05) and history of abuse substances currently (p<0.05). High coronary heart disease prevalence along with an upward trend was observed in Bangladeshi adults and older age. Proper strategies are required for primary prevention of coronary heart disease so that a further increase can be alleviated and the morbidity and mortality associated with it can be reduced. J.
