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.
I 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. |
