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
