Studying OSA may contribute towards a better understanding of current concepts of atherogenesis and in guiding therapy.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Methods<\/jats:title>\n<jats:p>We conducted this cross-sectional study among 66 patients with acute coronary syndrome (ACS) in a tertiary care hospital from 1 January 2019 to 30 June 2020. We included patients of ST elevation myocardial infarction (STEMI)\/ non-STEMI (on achieving Killip class I\/II) and unstable angina and performed in-hospital overnight polysomnography (PSG) within 8 weeks of index event. Apnoea\u2013hypoapnoea index (AHI) value 5\u2013&lt;15 was defined as mild OSA, AHI 15\u2013&lt;30 as moderate OSA and AHI &gt;30 as severe OSA.

Forty-three (65.1%) patients had STEMI, 19 (28.7%) had non-STEMI and 4 (6%) had unstable angina. On PSG, the prevalence of OSA (AHI&gt;5) was 78.8% (95% CI 67.0\u201387.9).
