摘要 目的:评价冠脉慢性闭塞病变再通对患者心功能的影响。方法:对冠脉造影证实的冠脉≥1支慢性闭塞的35例患者,采用冠脉介入治疗(PCI:PTCA加支架植入术)或冠脉旁路移植术(CABG),使再血管化,比较治疗前和治疗后3~6个月患者的临床心功能状态和左室射血分数(LVEF)的改变。结果:22例患者行PCI治疗,13例患者行CABG。平均随访4.2个月。治疗后临床心功能状态改善2级以上者27例(77.1%),改善1级者6例(17.1%),无改善者2例(5.8%),总有效率94.2%。LVEF较术前显著改善(术前51.6%±5.8%,术后62.2%±11.3%,P<0.01)。结论:PCI和CABG开通慢性闭塞冠脉能够改善患者的心功能和LVEF。 Objective: To evaluate the effect of revascuiarization on heart function status and left ventricular ejection fraction (LVEF) in patients with chronic total occlusion of one or more than branch of coronary artery. Methods: Thirty-five patients with chronic total occlusion at least one branch of coronary artery were studied. All the patients underwent percutaneous coronary intervention ( PCI ) or coronary artery bypass graft ( CABG ) for revascularization. Heart function was assessed clinically by exercise capacity and LVEF assessed with 2 - D echocardiography. the data obtained before procedural and 3 ~ 6 months thereafter were compared. Results: The revascularization was completed in 22 patients with PCI and 13 patients with CABG. The mean follow-up period was 4. 2 months. 27 patients (77. 1%) had NYHA heart function class improvement of 2 classes, and 6 patients (17. 1%) of 1 class, while 2 patients with no improvement. LVEF increased significantly from 51. 6%±5. 8% before rovascularization to 62.2%±11. 3% 3~6 months after procedure (P<0. 01). Conclusion: PCI and CABG can improve the heart function in patients with occluded coronary.
