Background : Patients with coronary artery disease and decreased left ventricular function have a poor prognosis, We have studied short-term change of left ventricular function and geometry for patients with impaired left ventricular function undergoing coronary artery bypass graft (CABG).
Methods : We retrospectively studied 35 patients with stable coronary artery disease and poor left ventricular ejection function (<40%) with regional wall motion abnormalities, enrolled between 2004 and 2012. All patients undergoing conventional coronary artery bypass surgery and we excluded those with off-pump CABG, emergency operation and Left ventricular aneurysm patients. During Follow-up period, we studied the change of left ventricular end diastolic dimensions (LVEDD), left ventricular end systolic dimension (LVESD), left ventricular ejection fractions (LVEF) and grade of mitral regurgitation (MR).
Results : The mean age of the patients was 63±8.6 years, and 83% of patients were men. The mean number of graft anastomosis was ??±? and the left internal mammary artery was used in all cases. In postoperative one month, one year and three years echocardiogram, LVEDD decreased from 60.4±3.8 to 56.4±6.1 (p=0.01), 55.6±7.9 (p<0.01) and 55.4±8.1 (p<0.05). LVESD decreased from 50.9±4.5 to 45.7±7.4 (p<0.01), 42.7±9.3 (p<0.01) and 43.7±9.2 (p<0.01). LVEF increased from 30.3±7.1 to 36.8±9.2 (p<0.01), 42.0±12.7 (p<0.05) and 41.1±11.3 (p<0.05). MR grade decreased from 1.0±0.7 to 0.6±0.8 (p<0.01) at postoperative one month but there were no significant difference during follow-up period, 0.7±1.1 (p>0.05) and 0.8±1.1 (p>0.05).
Conclusion : These results showed that the short term results of myocardial revascularization for ischemic dilated cardiomyopathy is associated with good LVEF and reverse left ventricular remodeling. However, the prospective long-term follow-up studies would be needed.
