Results of coronary artery bypass grafting alone and combined with surgical ventricular reconstruction for XXXX .

@entity1 @entity712
In this study, we included 236 @entity1 with @entity712 and ejection fraction (EF) <35% who underwent surgical treatment. @entity1 were randomized in two groups. There were 116 @entity1 who underwent coronary artery bypass grafting (CABG) with surgical ventricular reconstruction (SVR) and 120 @entity1 who underwent CABG alone. The hospital mortality rate was 5.8% after isolated CABG and 3.5% after CABG combined with SVR. All survivors had follow-up investigation from four months to five years, with a mean follow-up time of 31  13 months. The mean New York Heart Association (NYHA) functional class decreased from 2.9  0.5 to 2.2  0.7 one year after CABG and from 3.1  0.4 to 2.0  0.6 one year after CABG with SVR. We showed that left ventricular reconstruction significantly decreased EDV from 237  52 to 176  30 and correspondingly increased EF from 32  6 to 39  9. However, after isolated CABG EF did not increase significantly (32  7 preoperatively and 34  11 postoperatively). One- and three-year rates were 95% and 78% after SVR with CABG and 83% and 78% after CABG alone. Despite the more aggressive surgical strategy, left ventricular reconstruction did not increase operative mortality and early results were significantly effective compared with coronary artery bypass grafting alone.
