| Popis: | Objectives: The aim of this study was to assess the recovery of regional myocardial function of the left-ventricular septal wall and the septal site of the mitral valve (MV) annulus by tissue Doppler imaging (TDI). Methods: In 63 (32 diabetic and 31 control) patients having off-pump coronary artery bypass grafting (OPCABG), including the left internal mammary artery (LIMA) and the left anterior descending coronary artery (LAD), TDI measurements were performed before operation (baseline), 5 min after LIMA-LAD revascularization (early reperfusion) and after completion of all anastomoses (after revascularization). Results: Compared to the patients with diabetes, the controls had higher peak systolic velocities of the mid 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 decreased in the diabetic patients compared to the controls. There was no difference between the groups with respect to the velocities acquired at the septal site of the MV annulus. Conclusions: This study demonstrates an insufficient recovery of regional myocardial function in patients with type II diabetes undergoing OPCABG. |
