ABSTRACT
Objective To invesgate the safety and efficacy of the second generation biodegradable polymer Cobalt-Chromium sirolimus-eluting stent (EXCEL2) stent in diabetic patients by a subgroup analysis of of the CREDITⅡand CREDIT Ⅲ trials. Methods All patients who were implanted with the EXCEL2 stent were enrolled in the CREDITⅡand CREDIT Ⅲ trials. The primary endpoint was target lesion failure at 24-month, defi ned as a composite of cardiac death, target vessel myocardial infarction (TV-MI) and target lesion revascularization(TLR). The secondary endpoint was endpoints including all-cause death, all myocardial infarction (MI) or any revascularization.Results A total of 828 patients were included from the patients who were implanted with the EXCEL2 stent in the CREDIT II and CREDIT Ⅲ trials. 24-month follow-up rate was 99.5%. There was no significant difference in the primary endpoint (P>0.05) and event rates of the secondary endpoints(P>0.05) between the diabetic and non-diabetic group, which included all-cause death[diabetics (2.5%)vs.non-diabetics(1.4%),P>0.05],myocardial infarction(MI)(7.5% vs.5.0%,P>0.05),all from of revascularization(5.0% vs.3.9%,P>0.05),and stent thrombosis(0.6% vs.0.4%,P>0.05).Conclusions EXCEL 2 stent met the objective performance goal on effcacy and safety, which can reduce make stent restenosis, target vessel revascularization ,with 160 diabetic cases among them, and stent thrombosis in diabetic patients.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Danshen Chuanxiongqin Injection (DCI) on the myocardial damage of unstable angina (UA) patients undergoing percutaneous coronary intervention (PCI).</p><p><b>METHODS</b>76 UA patients were randomly assigned to the test group (39 cases) and the control group (37 cases). Routine treatment of Western medicine and PCI were given to all patients. But 10 mL DCI was intravenously dripped to patients in the test group by adding in 250 mL normal saline three to five days before PCI, once daily, lasting for 7 to 10 days. Changes of platelet P-selectin positive expressions before and after medication, the thrombolysis in myocardial infarction (TIMI), myocardial perfusion (TMP) score, levels of creatine kinase-myocardial band (CK-MB) and troponin I (TnI) after PCI were observed in the two groups.</p><p><b>RESULTS</b>After medication the P-selectin positive expressions was lower in the test group than in the control group (2.45% +/- 1.42% vs 4.43% +/- 1.79%, P<0.05). After PCI the incidence of TMP 0/1, the levels of CK-MB and TnI were lower in the test group than in the control group at the same phase, showing statistical difference (P<0.05). No cardiac event occurred in the two groups during the hospital stay.</p><p><b>CONCLUSION</b>Administration of DCI before PCI could effectively inhibit the activation of platelets, improve post-operative myocardial blood perfusion, and lower the incidence of the myocardial damage.</p>
