Abstract              Background: Coronary Artery Disease (CAD), also well-known as ischemic heart disease (IHD) is one of the types of heart disease which is caused by inadequate supply of oxygen and blood toa portion of myocardium. The current World Health Organization (WHO) report, predicted around 7.4 million people to die due to CAD. Obesity (raised BMI- Body Mass Index) is a risk factor for CHD both directly and indirectly. Aim and Objectives: To study correlation of pulmonary function test with BMI in the patients with CAD. Material and Methods: It’s a prospective study conducted in Department of General Medicine after obtaining permission from the Institutional Ethics Committee. The duration of study was 2 years i.e. from January 2015 to December 2016. Inclusion and exclusion criteri as were adequately defined. Pulmonary Function Test was performed in the morning. Daily calibration of the machine using manual calibration syringe as per ATS specification is done. Results: A total of 117 patients were recruited in this study, out of which 64 were males and 53 were females. Females are commonly affected in 40-50 years of age while, for >50 year ages, males are more commonly affected. Out of the total patients evaluated, 54 had abnormal PFT‘s whereas 63 had normal. Average BMI for males was 23.8 whereas average BMI for females was 25.68.Conclusions: It was apparent from the study that pulmonary function is negatively correlated with BMI, as BMI increases pulmonary function decreases. As the mortality of CAD and obstructive/ restrictive disease is rising in India, along with the current practices of prevention and management of CAD patient serial PFT‘s can be a feature to be included in the follow up of these patients.
