Clinical Efficacy of Thrombus Aspiration on 5-Year Clinical Outcomes in Patients With ST-Segment Elevation Acute Myocardial Infarction Undergoing Percutaneous Coronary Intervention.

Background: Adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) was reported to promote better coronary and myocardial reperfusion. However, long‐term mortality benefit of TA remains controversial. The objective of this study is to investigate the clinical impact of TA on long‐term clinical outcomes in patients with ST‐segment elevation myocardial infarction (STEMI) undergoing primary PCI. Methods and Results: The CREDO‐Kyoto AMI Registry is a large‐scale cohort study of acute myocardial infarction patients undergoing coronary revascularization in 2005–2007 at 26 hospitals in Japan. Among 5429 patients enrolled in the registry, the current study population consisted of 3536 patients who arrived at the hospital within 12 hours after the symptom onset and underwent primary PCI. Clinical outcomes were compared between the 2 patient groups with or without TA. During primary PCI procedures, 2239 out of 3536 (63%) patients underwent TA (TA group). The cumulative 5‐year incidence of all‐cause death was significantly lower in the TA group than in the non‐TA group (18.5% versus 23.9%, log‐rank P<0.001). After adjusting for confounders, however, the risk for all‐cause death in the TA group was not significantly lower than that in the non‐TA group (hazard ratio: 0.90, 95% CI: 0.76 to 1.06, P=0.21). The adjusted risks for cardiac death, myocardial infarction, stroke, and target‐lesion revascularization were also not significantly different between the 2 groups. Conclusions: Adjunctive TA during primary PCI was not associated with better 5‐year mortality in STEMI patients

Clinical results after coronary stenting with the Genous Bio-engineered R stent: 12-month outcomes of the e-HEALING (Healthy Endothelial Accelerated Lining Inhibits Neointimal Growth) worldwide registry

Item does not contain fulltextAIMS: e-HEALING is a worldwide, internet-based registry designed to capture post marketing clinical data on the use of the Genous EPC capturing R stent. Rapid restoration of a healthy endothelial layer after stent placement by capturing circulating endothelial progenitor cells may reduce both stent thrombosis (ST) and in-stent-restenosis. METHODS AND RESULTS: We planned a 5,000 patient registry with >/=1 lesion suitable for stenting. The 12-month primary outcome was target vessel failure (TVF), defined as target vessel-related cardiac death or myocardial infarction (MI) and target vessel revascularisation. Secondary outcomes were the composite of cardiac death, MI or target lesion revascularisation (TLR), and individual outcomes including ST. A total of 4,939 patients received >/=1 Genous stent between 2005 and 2007. Baseline characteristics showed a median age of 63 years, 79% males, 25% diabetics, and 37% with prior MI. A total of 49% of lesions treated were ACC/AHA type B2 or C; 1.1 stents per lesion were used. At 12 months, TVF occurred in 8.4% and the composite of cardiac death, MI or TLR in 7.9%. Twelve-month TLR and ST were 5.7% and 1.1%, respectively. CONCLUSIONS: Coronary stenting with the Genous results in good clinical outcomes, and low incidences of repeat revascularisation and ST.7 p
