Abstract:

Abstract Aim: To clarify the value of dobutamine stress tissue Doppler in the evaluation of LV functional improvement after elective PCI. Methods: The study included 60 patients with hibernating viable myocardium proved by DSE referred for an evaluation of myocardial viability prior to revascularization. Hemodynamic and echocardiographic variables (LVEF, WMSI and TDI Sm) were assessed at rest and during stress. 1 month after PCI follow up echocardiography and TDI were done. Patients were divided into 2 groups: (Group I): 18 patients (30%) with no global functional recovery and (Group II): 42 patients (70%) with global functional recovery. Results: SBP, DPB, HR, EF, WMSI and (Sm) increased significantly at stress P = 0.001. After 1 month patients were divided into 2 groups according to functional recovery. There were no statistically significant differences between two groups neither as regards age, sex, risk factors (P > 0.05) nor as regards SBP, DBP, HR, rate/pressure product, EF and WMSI during stress but Sm increased during stress and after1 month follow up in Group II (P = 0.001).
