Abstract

Aims To describe the clinical characteristics, contemporary trends of in-hospital management and outcome of patients admitted for an acute coronary syndrome (ACS) with associated atrial fibrillation (AF). Methods We analyzed data from four Italian nationwide prospective registries, conducted between 2001 and 2014, including consecutive ACS patients. Results Out of 16,803 ACS patients, 1019 (6.1%) presented with concomitant AF: 668 with non-ST elevation (NSTE)-ACS and 351 with ST-elevation myocardial infarction (STEMI). As compared to no-AF patients, those with AF were older and had significantly more prior cardiac events and comorbidities (all p < 0.005). A progressive increase occurred over time in the rates of coronary angiography and percutaneous coronary intervention, both in NSTE-ACS (p for trend = 0.0002 and 0.0008, respectively) and STEMI patients with AF at admission (both p for trend < 0.0001), with trends similar to those observed in non-AF patients. Among STEMI patients, in-hospital mortality decreased by 50% in those without AF (7.5% in 2001 to 3.3% in 2014, p < 0.0001), with a similar decrease in those with AF (20% vs 10.7%, p = 0.20), even though not statistically significant. At multivariable analysis, AF on admission was not an independent predictor of in-hospital mortality [odds ratio (OR): 0.82; 95% confidence intervals (CI): 0.52–1.30; p = 0.41 for NSTE-ACS, and OR: 1.07; 95% CI: 0.73–1.57; p = 0.74 for STEMI]. Conclusions Over the last 14 years, the in-hospital management of ACS patients with AF has significantly improved as for patients without AF, with comparable effect in terms of outcome.
