Abstract

CABG carries a high risk in pts with ischemic cardiomyopathy. This study correlated clinical, catherization and echocardiographic parameters to in-hospital and late mortality in 81 consecutive pts with severe ischemic LV dysfunction (EF=10-35%, mean 25±6%) who had non-emergency CABG. Pts with primary valvular diseases were excluded. RESULTS: Six pts (7.4%) died in hospital and 5 died during follow-up for a survival rate of 83% at 30 months. By multivariate analysis, congestive heart failure, hypertension, diabetes, angina, echo LV volumes and shape and number of diseased vessels were not related to in- hospital or late mortality. Prior CABG (p<0.05), EF (p<0.04) determined by echocardiography and color Doppler moderate (n=11) or severe (n=2) mitral regurgitation (MR) due to LV dilation or papillary muscle dysfunction were related to in-hospital mortality (p<0.01). In-hospital mortality was 23% with and 4.4% without moderate/severe MR (p<0.05). All 9 pts with concomittant mitral surgery survived while 3/4 pts with moderate MR without repair died (p<0.03). Only EF was related to late survival (p<0.05, Figure). CONCLUSIONS: Severe LV dysfunction (echocardiographic EF≤20%) or significant MR by color Doppler presage a high mortality after coronary surgery. An EF of 21-35% with no important MR carries a low risk. Mitral surgery may reduce mortality when moderate or severe MR are present.
