Multi-Link冠状动脉内支架的临床应用和长期随访结果

Multi Link Intracoronary Stenting for Coronary Artery Disease:Short Term Outcome and Long Term Angiographic and Clinical Follow up Outcomes

目的 :评估 Multi- L ink冠状动脉内支架置入术的临床疗效。 方法 :总结和分析行 Multi- L ink支架置入术的 96例冠心病患者 ,并做长期临床随访和冠状动脉造影复查。 结果 :共置入 Multi- L ink支架 116只 ,平均每例 1.2 (1～ 4)只。急性心肌梗塞行直接冠状动脉内支架置入术 30只 ,初发原位病变 (De Novo) 34只 ,经皮冠状动脉腔内成形术 (PTCA )效果不满意 38只 ,非阻塞性内膜撕裂 9只和濒临闭塞(bailout) 2只 ,再狭窄病变 3只。手术成功率 99.0 %。住院期间死亡 1例 ,余无其他心脏事件发生。49.0 %患者于术后平均 17± 11个月复查冠状动脉造影 ,再狭窄率为 2 .1%。临床随访 2 7± 8个月 ,无临床心脏事件生存率为 91.6 %。 结论 :Multi- L ink冠状动脉内支架置入术是一种安全和有效的治疗冠心病的方法。

Objective:To assess the clinical efficacy of the Multi Link intracoronary stent in the management of coronary artery disease. Methods:A retrospective study of 96 patients with coronary artery disease,who had undergone the stenting was presented.Long term angiographic and clinical follow up were carried out. Results:One hundred sixteen Multi Link coronary stents were implanted(mean 1 2 stents per patient).The indications for stent implantation were as following:primary stenting for acute myocardial infarction in 30 lesions,de novo in 34 lesions,a suboptimal result in 38 lesions,non occlusive dissections in 9 lesions,bailout in 2 lesions and restenosis in 3 lesions.The overall procedural success rate was 99 0%.There was one death during hospitalization.Of them,forty seven patiens(49 0%)had a repeated angiography 17±11 months after coronary stenting,and the results showed that the rate of restenosis was 2 1%.During 27±8 months follow up period,there were no additional events and 91 6% of patients remained free of clinical cardiac events. Conclusions:The Multi Link stent exhibits favorable performance characteristics and appears to be safe and effective in routine angioplasty practice.
