- W4220961622 abstract "Surgical revascularization by coronary artery bypass grafting (CABG) is the gold standard treatment for coronary artery disease. But, in patients with severe left ventricular dysfunction (ischemic cardiomyopathy), the result of CABG is different from those with normal left ventricular function. The coronary artery disease pattern in the Indian subconti-nent is different from the western world, due to the diffuse nature of coronary involvement, the smaller size of native vessels, increased prevalence of diabetes mellitus and other risk factors, and more prevalence of severe left ventricular dysfunction. Most of the studies regarding the surgical outcomes in ischemic cardiomyopathy come from western countries. This study attempts to assess the outcomes of surgical management of ischemic cardiomyopathy in the Indian subcontinent.A single-center retrospective cohort study was conducted at Sree Chitra Tirunal Institute for Medical Sciences and Technology, Thiruvananthapuram. The data of CAD pa-tients, who underwent surgical coronary revascularization for severe LV dysfunction from January 2010 to December 2014, were collected from the hospital records and through tele-phonic interviews in a structured study proforma. A total of 146 patients satisfied the criteria and were followed up for a period of 5 years.The mean age of the study population was 55.6 (8.8) years. Male preponderance was observed (94.52%; N = 138). CABG alone was done in 62.3% (N = 91) of the study partici-pants. CABG with linear plication was done in 23.3% (N = 34), CABG with MV repair in 7.5% (N = 11), and CABG with DORS in 6.8% (N = 10). The majority of patients (N = 54, 37%) received 4 grafts. Thirty-day mortality observed in the study population was 11 (7.5%). The causes documented were cardiac causes in 9 (82%), cerebrovascular events in one (9%), and septicemia in one (9%). The mean of 5-year survival of the study population was 94.2 (3.5) months with 95% CI 87.32, 101.13. There was a substantial improvement in the degree of mitral regurgitation. Ejection fraction (EF) also showed improvement. The mean preoperative EF was 29.51 (4.84%) and that of post-op was 39.92 (9.0%).Despite the challenges of diffusely diseased coronary arteries, severe LV dysfunction, addressing associated significant MR and ventricular aneurysms, the outcome of surgical management of CAD with severe LV dysfunction, in the Indian population can be done with acceptable results. Randomized control studies in this subset can provide more solid evidence in this regard." @default.
