Abstract:
Objective To evaluate the effect of percutaneous coronary intervention (PCI) on chronic total occlusion (OCT) by doubutamine stress echocardiography. Methods Forth-six CTO patients were categorized into the reopening group and failed-reopening group based on the results of PCI. All patients had undergoing low dose doubutamine stress echocardiography before PCI and at 6-month follow-up, measuring rest and stress wall motion score index (WMSI) with semi-quantitative method. Cardiac volumes and ejection fraction were measured with 3D full volume echocardiographic. Results The two groups showed no differences in general clinical data and all baseline echocardiography data before PCI. During follow-up, the reopening group was observed to have improvement in ejection fraction[(60.00±3.22)% vs.(62.65±3.58)%,P=0.017)],and WMSI in stress status[(1.42±0.37)vs.(1.32±0.36),P<0.001], compared with pre-PCI results. The reopening group showed improvement in ejection fraction[(62.65±3.58)% vs.(57.7±5.61)%,P=0.001)]and WMSI in stress status[(1.32±0.36)vs.(1.62±0.47),P<0.001)],when compared with the failed-reopening group. Conclusions Low dose doubutamine stress echocardiography can be nsed for evaluation of the eff ect of revascularization of CTO. The cardiac volumes and contractile function representing by wall motion in stress status were improved after recanalization of CTO.
