title: Coronary artery bypass grafting for unstable angina. Risk factors of operative mortality.
abstract: In order to identify factors affecting early mortality in patients undergoing CABG for unstable angina, several risk factors have been analysed in a group of 120 patients. Systemic hypertension and left ventricular impairment were shown to be significant risk factors (Systemic hypertension, P less than 0.01; EF less than or equal to 0.35, P less than 0.01; LVEDP greater than or equal to 20 mmHg, P less than 0.025). Overall mortality rate was 5% (6/120). No influence could be recognized for age, sex, previous MI, emergency surgery, extension of coronary disease, completeness of revascularization and mode of onset of symptoms.
