经桡/尺动脉途径置入氮氧化钛涂层支架治疗老年冠心病

Titanium-nitride-oxide-coated stent implanted in transnlner or transradial approach for treatment of coronary heart disease in elderly patients

【摘要】目的探讨氮氧化钛涂层支架(TITAN2)在老年经桡/尺动脉途径行冠状动脉血运重建方面的临床治疗效果。方法共入选29例冠心病患者,男16例,女13例。均采用经桡动脉或尺动脉途径行冠脉血运重建。计算TITAN2支架病变的通过率、早期支架内血栓发生率及随访主要不良心脏事件(死亡、急性心肌梗死、再次血运重建)发生率。结果29例冠状动脉造影发现43处>75%狭窄病变,植入支架42枚,1枚支架未能通过病变(右冠状动脉),通过率97.7%。植入支架后无残余狭窄、支架脱载、内膜撕裂、支架内早期血栓形成及冠脉破裂。随访1～5个月,无主要心脏不良事件发生。结论TITAN2支架在老年冠脉血运重建方面临床应用效果良好。

【Abstract】Objective To investigate the use of titanium-nitride-oxide-coated stent (TITAN2) implanted in transulner or transradial approach for coronary revascularization in elderly patients with coronary heart disease(CHO). Methods Twenty-nine CHD patients(16 males and 13 females)who were about to undergo coronary revascularization were selected. All patients underwent coronary revascularization in trans-ulner or transradial approach. The passing rate of stent, early thrombosis in stent, and major adverse cardiac events(MACE) during 1-5 month follow-up were recorded. Results Coronary angiography revealed 43 lesions with stenosis >75% in 29 patients.Forty-two lesions were successfully revascularized by TITAN2. There was one failure in passing right coronary artery. The passing rate of stent was 97.7%. Remaining stenosis, stent dislocation, endarterium disection, early thrombosis in stent, and coronary rupture were not discovered after stent. No MACE was found during 1-5 month follow-up. Conclusion TITAN2 has significant efficacy on coronary revascularization in elderly CHD patients.?更多
