Myocardial revascularization for severe left ventricular dysfunction. Factors influencing early and late survival

摘要: The results of coronary bypass surgery have been assessed in 102 patients with severe left ventricular dysfunction who had a preoperative ejection fraction < or = 0.35 (mean (s.e.m.) 0.29 (0.01)). Independent risk factors influencing operative mortality were obesity (P 0.0290) and the need for intra-aortic balloon counterpulsation 0.0010). Cox regression analysis using as its end-point 'cardiac-related death' demonstrated three variables; 0.001), advanced age 0.011), 0.36). In subset 43 did not these factors, 4-year cardiac-related death rate was 95.1 (3.4)%. long-term survival can be expected to satisfactory dysfunction, provided they viable myocardium rather than myocardial fibrosis.
