金属裸支架植入治疗冠状动脉不同病变的远期疗效比较

目的探讨冠心病(CHD)患者植入金属裸支架(BMS)的远期疗效.方法随访植入BMS的CHD患者224例.随访指标:1)全因死亡;2)主要心脏不良事件(MACE);3)靶病变血管重建(TLR)、靶血管重建(TVR);4)支架内再狭窄和/或支架节段内再狭窄等.结果 224例中累积MACE发生率为35.7%,平均每年MACE发生率为4.58%.CAG复查的148例中,冠状动脉A型病变再狭窄率16.4%,B1型病变24.1%,B2型病变62.2%,C型病变66.7%.晚期管腔丢失率平均为(29.32±10.17)%.结论植入BMS治疗冠状动脉病变A型和B1型,远期MACE发生率和再狭窄率均较低,远期效果与安全性好.

Long-term Efficacy of Bare Metal Stents Implantation in Patients with Different Coronary Lesion Types

Objective To evaluate the long-term efficacy of bare-metal stent ( BMS ) implantation in patients with different coronary lesion types. Method A total number of 224 patients with CHD undergoing BMS implantation were enrolled. The main endpoint included the occurrence of the first major adverse cardiac event (MACE), target lesion revascularization ( TLR) and target vessel revascularization ( TVR). Restenosis was defined in diameter in-stent and in-segment of stent defined of both ends of stent implanted. Results The combined cumulative MACE rate of 224 patients was 35. 7% with an average of 4. 58% per year. In the cases of 148 followed by CAG,coronary artery restenosis rate was 16. 4% in type A lesion,24. 1% in type B1 lesions, 62. 2% in B2 type lesions and 66. 7% in type C lesions. The rate of Late lumen loss was an average of (29. 32± 10 . 17 )%. Conclusion BMS implantation was used to treat the selective coronary artery stenosis lesions such as type 1 and type B1 lesions,which showed low incidence rate of MACE and the rate of restenosis,good efficiency and safety in long-term.
