Abstract

Background The relationship between troponin and atrial fibrillation (AF) without acute coronary syndrome is still unclear. We sought to investigate the presence of coronary atherosclerosis and adverse outcomes in patients with AF. Methods Consecutive patients with recent-onset AF and without severe comorbidities were enrolled between 2004 and 2013. Patients with a troponin rise or with adverse outcomes were considered for coronary angiography and revascularization when "critical" stenosis (≥ 70%) was recognized. Propensity score matching was performed to adjust for baseline characteristics; after matching, no differences existed between the groups of patients with or without troponin rise. The primary end point was the composite of acute coronary syndrome, revascularization, and cardiac death at 1- and 12-month follow-ups. Results Of 3627 patients enrolled, 3541 completed the study; 202 (6%) showed troponin rise; and 91 (3%), an adverse outcome. In the entire cohort, on multivariate analysis, the odds ratio for the occurrence of the primary end point of troponin rise was 14 (95% confidence interval [CI], 10-23; P
