Aims and Objective: The aim of this study was to describe the occurrence of sleep disordered breathing/obstructive sleep apnea (OSA) in patients admitted with acute myocardial infarction (MI) in a tertiary care hospital. Materials and Methods: All consecutive patients with a recent MI, presenting to the hospital for a period of over 1 year, were administered with a well-designed questionnaire and subjected to polysomnography (PSG) after obtaining a written informed consent. Results: A total of 55 patients were screened with the questionnaire and 44 patients were subjected to PSG. Of the 55 patients 42 (76.4%) were snorers and 14 (25.5%) were insomniacs. OSA was diagnosed in 12 (28.6%) of the 44 patients. There was no significant difference in the presence of hypertension, diabetes mellitus or hypercholesterolemia among the patients diagnosed with OSA and those without OSA. Conclusions: There is a high prevalence of previously undiagnosed OSA in patients admitted to the hospital with acute MI as compared to the general population. OSA is under-recognized in India. Early recognition of undiagnosed OSA in this population of patients with coronary artery disease (CAD), and treatment of the same would help in reducing cardiovascular morbidity and mortality. This study reinforces the need for the routine screening of MI/CAD patients for the presence of OSA
