Postoperative atrial fibrillation (POAF) is the most common arrhythmia after cardiac surgery. There exist consistent experimental and clinical data suggesting that aldosterone antagonists (AAs) may exert beneficial effects regarding electrical and structural remodeling in failing myocardium. Recently, eplerenone (EPL) has been found to reduce the incidence of nonsurgical AF when added to guideline-recommended therapy in patients with systolic heart failure. ⋯ In the nonAA group (EF = 35.8 ± 6%) 90/200 patients (45%) had POAF, while in the AA group (EF = 36.2 ± 5%) only 40/132 patients (30.3%) developed POAF (P < 0.01, χ (2) test). Multivariate logistic regression analysis revealed that only AAs and left atrial diameter significantly affected the development of POAF even when adjusted for other clinical variables (P < 0.05). In conclusion, AAs significantly reduced the incidence of POAF when added to standard heart failure therapy in patients undergoing on-pump cardiac surgery.

Randomized Controlled Trial Multicenter Study Comparative Study
Gender differences in patients with cardiogenic shock complicating myocardial infarction: a substudy of the IABP-SHOCK II-trial.
Cardiogenic shock (CS) complicating acute myocardial infarction (AMI) is associated with high mortality. Previous studies regarding gender-specific differences in CS are conflicting and there are insufficient data for the presence of gender-associated differences in the contemporary percutaneous coronary intervention era. Aim of this study was therefore to investigate gender-specific differences in a large cohort of AMI patients with CS undergoing contemporary treatment. ⋯ In this large-scale multicenter study in patients with CS complicating AMI, women had a worse-risk profile in comparison to men. No significant gender-related differences in treatment as well as short- and long-term outcome were observed.
