Is the female gender an independent predictor of adverse outcome after off-pump coronary artery bypass grafting?
GROUND: The female gender is an independent predictor of adverse outcome after conventional coronary artery bypass grafting using cardiopulmonary bypass. The aim of this study is to assess the effect of the female gender on the outcome after off-pump coronary artery bypass (OPCAB) surgery. METHODS: This study is a retrospective review of 413 consecutive patients (181 women and 232 men) who underwent OPCAB between January 1999 and May 2001. Adverse outcomes were divided into minor adverse outcomes (MINAO), major adverse outcomes (MAJAO), and prolonged length of stay (PLOS) more than 7 days. MINAO included atrial fibrillation, respiratory complications except adult respiratory distress syndrome, and any wound infection except mediastinitis. MAJAO included stroke, myocardial infarction, renal failure, adult respiratory distress syndrome, mediastinitis, low cardiac output, mechanical ventilation more than 24 hours, intensive therapy unit stay more than 24 hours, gastrointestinal complicati
