Prognosis of patients with atrial fibrillation undergoing percutaneous coronary intervention receiving drug eluting stents

Atrial fibrillation (AF) is increasingly prevalent in elderly patients and adversely affects clinical outcomes after coronary artery bypass grafting, non-cardiac surgery or myocardial infarction. Aim of the present analysis was to investigate the prognostic impact of AF in patients undergoing drug eluting stent (DES) implantation during a 1-year follow-up. 5,772 consecutive patients undergoing percutaneous coronary intervention were enrolled into the German Drug Eluting Stent Registry (DES.DE) and were followed for 12 months. Of these 455 had AF and 5,317 in sinus rhythm served as controls. Univariate and multivariate logistic regression analyses were used to determine the risk of major adverse cardiac and cerebrovascular events (MACCE) and bleeding complications. Patients with AF were older (71.3 +/- A 7.6 vs. 64.7 +/- A 10.5 years) and had a higher prevalence of diabetes, hypertension, renal insufficiency as well as more prior bypass surgery, stroke and peripheral arterial disease. Cardiogenic shock (2.9 vs. 1.4 %; p < 0.05), left ventricular ejection fraction a parts per thousand currency sign40 % (21.0 vs. 11.4 %; p < 0.0001) and triple vessel disease (44.4 vs. 37.9 %; p < 0.01) were more frequent in patients with AF than in controls. MACCE (OR 2.08, 95 % CI 1.56-2.77), total mortality (OR 3.27, 95 % CI 2.32-4.62) and non-fatal stroke (OR 2.03, 95 % CI 1.03-4.00) as well as bleeding complications (OR 1.88, 95 % CI 1.13-3.12) during the 1-year follow-up were more frequent in patients with AF (univariate analysis). In multivariate analyses adjusting for covariates determined to be relevant at baseline, the risk for total mortality remained elevated (OR 1.63, 95 % CI 1.05-2.52). AF is an important predictor of long-term mortality in patients undergoing DES implantation.
