Abstract
The aim of the current study was to evaluate the safety and clinical efficacy of arsenic trioxide drug-eluting (AVI) stents, manufactured in China, for the treatment of coronary heart disease (CHD). Between January and August 2014, 40 patients with CHD admitted to Yongchuan Hospital with implanted AVI stents alone were selected. A one-year clinical follow-up was completed and one year postoperative coronary angiography was reviewed. Major adverse cardiovascular events (MACE), recurrent angina, stent restenosis and stent thrombosis cases were detected. All 40 patients with CHD completed the one-year clinical follow-up, as well as the one-year postoperative coronary angiography. The follow-up results indicated that the MACE rate was 15.0% (6/40), the target lesion revascularization rate was 15.0% (6/40), the angina recurrence rate was 32.5% (13/40), the in-stent restenosis rate was 20.0% (8/40) and the stent thrombosis rate was zero. There were no cases of cardiac death or nonfatal myocardial infarction. The incidence of restenosis was higher following implantation of the AVI stent and the safety and clinical efficacy were worse than expected.
