Does Diabetes Have an Influence on Regional Deformation Parameters in Patients with Normal Systolic Function during Off-Pump Coronary Artery Bypass Grafting?

The aim of this study was to evaluate the recovery of regional myocardial function of the left- ventricular septal wall and septal site of the mitral valve (MV) annulus by tissue Doppler imaging (TDI). In 63 (32 diabetic and 31 control) patients having off-pump coronary artery bypass grafting (OPCABG), including the left internal mammary artery (LIMA), TDI measurements were performed before operation (baseline), 5 min after LIMA-LAD revascularization (early reperfusion) and after completion all anastomoses (after revascularization). Compared to the patients with diabetes, the controls had higher peak systolic velocities of the mild septal segments in the early reperfusion measurement (p=0.002). After revascularization, values of peak systolic strain at the basal (-10.13 vs. -13.36%, p=0.044) and mid septal segments (-8.25 vs. -12.69%, p=0.009) were desrease in the diabetic patients compared to the controls. Conclusions: This study demonstrates an insufficient recovery of regional myocardial function in patients with type II diabetes undergoing OPCABG.
