Long-term outcomes of patients with coronary heart disease treated with domestic sirolimus-eluting Partner coronary stent

Objective To evaluate the safety and efficacy of domestic sirolimus-eluting Partner coronary stent in treating coronary artery disease.Methods The 12-month follow-up results of Partner coronary stent implantation in 1 352 coronary heart disease(CHD) patients from 21 medical centers were retrospectively analyzed.The primary endpoint was event rate of cardiac death,myocardial infarction(MI),target vessel revascularization(TVR),major adverse cardiac event(MACE) and stent thrombosis.Results Implantation of 1 869 Partner coronary stents was successfully performed in 1 352 CHD patients.Diabetes patients were 23.3%;patients with acute coronary syndrome were 90.49%;type C lesions were 30.98%;bifurcation lesions were 11.13% and chronic total occlusion(CTO) lesions were 7.81%.The average length of target lesions was 21.99±10.57 mm;average stenosis rate was 88.18%±10.93% and the reference vessel diameter was 3.17±1.81 mm.The maximum dilation pressure was 13.77±3.01 atm.Pre-dilation was performed in 78.12% of the lesions while post-dilation was performed in 25.79% of the lesions.Follow-up results showed that12-month cumulative cardiac death rate was 0.52% and the insidence of MI,TVR and MACE was 0.96%,2.14% and 3.62% respectively.Cumulative thrombosis rate was 0.66% and was comparable to the results in other studies.Conclusion Domestic sirolimus-eluting Partner coronary stent can be safely implanted in severe CHD patients with ideal outcomes.
