We assessed longitudinal changes in apnea-hypopnea index (AHI) and sleep apnea phenotype after STEMI and determined its association with changes in the left ventricular ejection fraction (LVEF).<h4>Methods</h4>A total of 101 eligible patients with STEMI underwent consecutive sleep studies and echocardiographic studies within 5 days of admission and at 6-month follow-up. Sleep apnea (AHI ≥ 15 events/h) was further divided into obstructive sleep apnea (OSA) or central sleep apnea (CSA).<h4>Results</h4>Both AHI (mean difference -6.4 events/h, 95% confidence interval [CI] -9.6 to 3.3, <i>P</i> < .001) and LVEF (mean difference 2.6%, 95% CI 1.3 to 4.0, <iJournal of clinical sleep medicine : JCSM : official publication of the American Academy of Sleep Medicine1773-1781https://www.ebi.ac.uk/biostudies/studies/S-EPMC6175802biostudies-literatureSleep Apnea Evolution and Left Ventricular Recovery After Percutaneous Coronary Intervention for Myocardial Infarction.PMC6175802Lee CHBalakrishnan ISeneviratna ALing LHChan MYTing JGong LTai BCTai ESRichards AMTan LLfalseSleep Apnea Evolution and Left Ventricular Recovery After Percutaneous Coronary Intervention for Myocardial Infarction.<h4>Study objectives</h4>Sleep apnea is often newly diagnosed in patients presenting with ST-segment elevation myocardial infarction (STEMI).
