Abstract 13309: Atrial Fibrillation Predicts Hospital Mortality in STEMI but not in NSTE-ACS in Clinical Practice - Results of the Euro Heart Survey ACS-Registry
Background: Atrial fibrillation (Afib) is the most common supraventricular arrhythmia in patients with acute myocardial infarction (MI), nevertheless little is known about its influence on the choice of therapeutic strategy and the clinical course of these patients.
Methods: Between Oct 2006 and Oct 2008, consecutive patients with ACS were enrolled into the Euro-Heart-Survey ACS-Registry to document treatment and hospital complications. We examined the impact of Afib at admission on outcome of STEMI and of NSTE-ACS in clinical practice in Europe.
Results: Out of 19,201 patients with ACS, 433 patients with STEMI (5.7%) and 987 patients with NSTE-ACS (8.5%) had Afib. Patients with Afib were older, more often female and had a significantly higher prevalence of relevant comorbidities independent on the kind of ACS. Patients with Afib were less likely to undergo primary PCI in STEMI or early PCI in NSTE-ACS as compared to patients without Afib. Hospital mortality was higher for Afib patients with STEMI but not for those with NSTE-ACS. After correction for the differences in baseline characteristics and differences in acute treatment, Afib was an independent predictor of hospital mortality in STEMI (OR 1.6, 1.07-1.98), but not in NSTE-ACS (OR 1.25, 0.91-1.72).
Conclusion: Afib was an independent predictor of hospital mortality in STEMI (with 60% higher risk for death), but not in NSTE-ACS.
