Background: The incidence and prevalence rates of heart failure (HF) are increasing worldwide. The prevalence of HF rises exponentially with increasing age and affects 4% to 8% of people older than 65. The leading causes of HF in India include coronary artery disease (CAD), diabetes, hypertension, rheumatic valvular heart diseases and primary cardiac muscle diseases. Rheumatic heart disease (RHD) is still a common cause of HF in India. Epidemiological studies have estimated that 1.5% to 2% population experience HF and it is the main reason for hospital admission of elderly patients. The objective of this study was to establish the etiological factors of heart failureMethods: A cross sectional study of 150 patients above the age of 18 years presented with heart failure diagnosed clinically on the basis of Framingham heart failure criteria and echocardiography, done over a period of one year in department of medicine in BRD medical college Gorakhpur Uttar Pradesh.Results: A total of 150 patients were include in this analysis the majority of patients were male (57.3%). Age of patients ranged from 18 - 70 years and 84% patients were above the age of 40 years.Conclusions: Heart failure was more prevalent in elderly male above 40 years of age. Myocardial infarction, DCMP, rheumatic heart disease and hypertensive heart failure are the common etiology leading to heart failure.
