[Aortocoronary venous bypass operation in the elderly].

On the extended diagnosis for an aorto-coronary venous bypass operation, with a greater involvement of patients with instable angina pectoris symptomatik (inApS), left main artery disease (LAD), aneurysmal resection, and "bad" ventricle (ejection fraction global less than or equal to 30%), the preoperative risk was evaluated in n = 600 patients. In a total of n = 150 patients with preoperative high-risk constellation perioperative parameters were monitored to find complications (perioperative myocardial damage [PMD], cardiac low output syndrome [LOS]). Among them were n = 40 patients aged greater than 60 years (60-72), their average age being 62.
