Abstract

As an important parameter of cardiac functions, QT interval is usually irregular in patients with chronic coronary artery total occlusion (CTO). We sought to determine the effect of coronary revascularization (CRV) on QT interval dispersion in patients with CTO. To this end, we used electrocardiogram of 12 leads to record changes in the QT interval dispersion in 22 patients with CTO treated with percutaneous coronary intervention (PCI) and 24 patients treated with coronary artery bypass grafting (CABG). Our data showed that QTd and QTcd diminished markedly (P < 0.01) after PCI or CABG. No significant difference was observed between the postoperative groups (P > 0.05) or between PCI and CABG groups. We concluded that CRV could diminish QTd and QTcd in patients with CTO with no distinguishable differences with PCI and CABG procedures. Therefore, CRV can revitalize the existing functional myocardium and resume the myocardial electrophysiological functions in patients with CTO.
