Abstract:
Objective To determine whether the 12-lead-resting electrocardiogram(ECG) is a predictor of left vertricular(LV) recovery after successful recanalization of chronic total coronary occlusions(CTO).Methods The 12-lead-resting ECG was evaluated for Q-wave areas and parameters of QT dispersion.Impairment of regional wall motion was evaluated by real-time three-dimensional echocardiography(RT-3DE) at baseline and at follow-up.Results The wall motion score index(WMSI) was improved from 1.56?0.31 to 1.12?0.21(P0.05).Conclusion In patients with recanalization of CTO,recovery of regional wall motion is reliably predicted by analysis of the12-lead-resting ECG.
