Background and objectives: Many subjects with coronary artery disease have viable but dysfunctional myocardium, where akinetic or severely hypokinetic myocardium keeps the ability to contract if perfusion improves.
We sought to detect the echocardiographic parameters for prediction of left ventricle functional improvement after revascularization using tissue doppler
in addition to conventional echocardiography.
Material and methods: It was a prospective and predictive study which included 100 patients who presented to the Cardiology Department at Benha University Hospitals for evaluation of viability prior to revascularization , the study was accepted and legalized by ethical research commitee. Patients were subjected to: full clinical examination, 12 leads ECG and echocardiographic variables (LVEF and TDI) were assessed at rest and during stress, 3 month after PCI follow up echocardiography and TDI were done to all patients then were devided to group I 30 patients (30% ) with functional recovery and groupe II 70 patient (70% ) without functional recovery .
Results: There were no statistically significant differences between two groups neither as regards age, sex, risk factors (P >0.05) , heamodynamic variants and WMSI during stress but Sm and EF increased during stress and after 3 months follow up in Group II (P = 0.001).
Conclusions: Baseline EF and stress TDI showed great accuracy in predicting left ventricular functional recovery after elective PCI.
Key words: Elective PCI , Dobutamine stress echocardiography, left ventricular functional recovery.
List of Abbreviations: PCI:percutaneous coronary intervention, LVEF :left ventricular ejection fraction , TDI : tissue Doppler imaging.
