Prognostic impact of atrial fibrillation in acute coronary syndromes: results from the ARIAM registry.

Aims: The prognostic ability of atrial fibrillation (AF) in acute coronary syndromes (ACS) is unclear. Studies regarding patient outcomes with respect to the timing of AF are scarce and conflicting. The present study aimed to determine the frequency, predictors and impact on clinical outcome of AF in patients with ACS.
