Satisfactory results are achieved by elective coronary artery bypass grafting (CABG), but the results of emergency CABG are less than satisfactory and readmission for cardiac events is common. We examined long-term results of emergency CABG for unstable angina pectoris from the viewpoints of preoperative, intraoperative, and postoperative factors. Subjects were 154 patients who underwent emergency CABG for unstable angina pectoris. Operative mortality rate was 1.9%. Univariate analysis showed female gender, chronic renal failure, hemodialysis, nonuse of human atrial natriuretic peptide (hANP), nonuse of angiotensin II receptor blockers and aldosterone blockers, 3-month postoperative brain natriuretic peptide level > or =200 pg/ml, and 3-month postoperative aldosterone level > or =100 pg/ml as risk factors for late cardiac events. Multivariate analysis confirmed nonuse of hANP, nonuse of aldosterone blockers, 3-month brain natriuretic peptide level > or =200 pg/ml, and 3-month aldosterone level > or =100 pg/ml as risk factors. Intraoperative hANP infusion and postoperative treatment with aldosterone blockers and angiotensin II receptor blockers can control the renin-angiotensin-aldosterone system, inhibit left ventricular remodeling, decrease extent of infarction, and improve cardiac function, yielding a favorable long-term prognosis. The best results are obtained by combining good surgical technique and perioperative management with the long-term outcome in mind.
