Abstract              Background: Cardiovascular diseases (CVDs) are a group of disorders of the heart and blood vessels and comprise CAD. CVDs are the number one cause of death globally. CAD is responsible for mortality and morbidity in developed and developing countries. It is a leading cause of death in India. Aim and Objectives: To assess pulmonary function among established stable coronary artery disease patients 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 criterias 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. When the type of pulmonary condition among study participants with CAD is considered, significantly more number of patients have restrictive pattern (29.06%) as compared to obstructive pattern (17.09) of pulmonary function. Conclusions: There were significantly more number of patients had restrictive pattern of pulmonary function. 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.

Key Words: Coronary Artery Disease, Pulmonary Function Test.
