运动训练对大管径冠状动脉支架再狭窄率的影响

目的：探讨运动训练对接受直径≥3．0mm的冠状动脉药物支架患者再狭窄率的影响。方法：回顾性分析接受管径≥3．0mm药物支架，并获得6个月临床和冠状动脉造影随访的90例患者（95个病变）的资料（心肌梗死、慢性完全闭塞病变、再狭窄及桥血管病变除外）。根据是否进行运动训练患者被分为运动训练组（42例）和非运动训练组（48例），对其6个月支架内再狭窄率进行对比研究。结果：运动训练组的再狭窄率明显低于非运动训练组（9．5％比18．8％，P〈0．05）。结论：对于接受管径≥3．0mm的冠状动脉支架患者，运动训练也是减少再狭窄率的有效方法。

Effect of exercise training on restenosis rate for patients with large coronary drug-eluting stent implantation

Objective： To investigate effect of exercise training on restenosis rate in patients undergoing coronary drug-- eluting stent （DES, ≥3.0 mm） implantation. Methods： The data of 90 patients （95 lesions） were retrospectively an alyzed. All patients （myocardial infarction, chronic total occlusion lesions, restenosis and bridge vessel were exclu- ded） received six--month clinical and coronary angiographic follow-up. According to exercise training, patients were divided into exercise training group （n=42） and non-exercise training group （n=48）, and their restenosis rates within six months were compared and analyzed. Results： Restenosis rate in exercise training group was significantly lower than that of non-exercise training group （9.5% vs. 18.8%o, P〈0.05）. Conclusion： Exercise training is an effective method for reducing restenosis rate in patients undergoing DES （≥3.0mm） implantation.
