Abstract

Atrial fibrillation (AF) is a common comorbidity among patients presenting with acute ST-segment elevation myocardial infarction (STEMI). Previously, small studies have reported an association between AF and poorer outcomes among STEMI patients. We performed this study to investigate the impact of AF on in-hospital outcomes in STEMI patients treated with primary percutaneous coronary intervention (PPCI) using a large national database. The study population constituted of patients 18 years and older with a primary discharge diagnosis of STEMI and who underwent PPCI. Using a 2:1 matching protocol, matched groups of AF (N = 24,680) and non-AF (N = 49,198) patients were developed. Among 1,493,859 STEMI patients who underwent PPCI, 129,354 (8.7%) patients had AF. In the propensity-matched cohort, adjusted in- hospital mortality was significantly higher for patients with AF compared to patients with no AF (10.3% vs 9.4%) (Adjusted OR: 1.10; CI= 1.06-1.16; p
