Abstract

Sleep disorders such as Obstructive Sleep Apnea (OSA) lead to oxygen desaturation, sleep fragmentation and tissue suffering • OSA is a major cardiovascular risk like hypertension, diabetes and obesity • Therapy with CPAP do not prevent cardiovascular events in patients with moderate-to-severe obstructive sleep apnea and established cardiovascular disease • To date, the effect on clinical outcomes in Acute Coronary Syndrome (ACS) is debatable METHODS • We prospectively analyzed patients with ACS admitted to Policlinico Gemelli Cardiac Coronary Unit (CCU) from May 2019 to September 2019 (NCT04002739) • Patients performed a sleep study within 72 hours since admittance and at 3-month. Also, we performed Echocardiography, Coronary angiography, 24h-ECG monitoring, measurements of the levels and peaks of biomarkers for cardiac injury, nt-proBNP atrial peptide peak and percentage of extracellular water (ECW) assessed by bioelectrical impedance analysis. • At 3-month, patients did not have any intercurrent treatment for sleep apneas such as CPAP. • SAS software (9.4) was used to analyze the data and changes were assessed using a paired t-test The mean features of STEMI and NSTEMI patients were: Age 64.8 63.5 BMI (Kg/m2) 25.9 27.2 AHI (events/h) 37.5 30.7 ODI (events/h) 32.0 27.1 Nt-proBNP peak (ng/L) 1555 1455 LVEF (%) 49.8 54.5 The 3-month analysis did show a remarkable, spontaneous improvement of sleep disorder (ΔAHI: -12.5±2.9; CI 6.5-18.5; p=0.0002). Suggestions: 1. The impact of sleep disorders in Acute Coronary Syndromes is, still, questionable 2. We report on a significant, spontaneous change in sleep apnea syndrome in ACS at 3-month 3. OSA severity is associated with myocardial infarction extension and the 3-month AHI reduction was greater in the STEMI group compared to the NSTEMI one 4.
