The risk factors of emergency coronary artery bypass grafting in the elderly

: The purpose of this study was to evaluate the risk factor of emergency coronary artery bypass grafting (CABG) in the elderly. From January 1986 to December 1998, there were 37 patients of emergency CABG in 75 years old and over. They were divided into two groups (alive: 27 patients and dead: 10 patients). The risk factors that influenced the mortality were preoperative chronic renal failure and cardiogenic shock, prolonged cardiopulmonary bypass time and aortic cross clamp time, postoperative mediasinitis and perioperative cerebrovascular accident. In conclusion, the predictors of operative mortality of emergency CABG in elderly were preoperative cardiogenic shock and renal dysfunction.
