    Abstract:
    OBJECTIVE: To determine the early effects of Coronary Artery Bypass Grafting (CABG) on regional left ventricular wall motion abnormality in patients undergoing surgery for proven Coronary Artery Disease (CAD). DESIGN: Quasi-experimental study. PLACE AND DURATION OF STUDY: Department of Cardiac Surgery, National Institute of Cardiovascular Diseases, Karachi. from October 2005 to April 2006. PATIENTS AND METHODS: A total of a 100 adult patients who underwent elective CABG were selected. Pre-operative echocardiography was done to note if segmental left ventricular wall motion at basal, mid and apical levels were normal, hypokinetic, akinetic, dyskinetic, or aneurysmal. Postoperative echocardiography was done between 4th and 6th day and change in left ventricular segmental wall motion was noted. RESULTS: Seventy-five patients (n=75) were included in the analysis. These results showed that effect of CABG on anterior segmental wall motion abnormalities was insignificant (p=.609), the effect on the anterior IVS showed deterioration of segmental wall motion and this effect was significant (p=.001), effect is insignificant on anteriolateral segmental wall motion abnormalities (p=.078), normal pre-operative segments in posterior wall showed stability (p=.664) while disappearance of dyskinetic, reduction in akinetic segments postoperatively and inferior wall motion have same effects as of posterior wall. Comparison of pre-operative and postoperative echocardiographic data revealed early improvement in segmental wall motion of posterior and inferior wall, while alterations in segmental wall motion of anterior, anterior-lateral and septal wall. CONCLUSION: Myocardial revascularization by CABG improves early left ventricular regional wall motion abnormalities where SVG is used as conduit for revascularization whereas no significant improvement occurs in early segmental wall motion in areas revascularized by LIMA.
