Background: Limited data are available regarding the direct comparison of angiographic and clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) for chronic total occlusion (CTO). Methods and Results: A prospective, randomized, multicenter trial was conducted to evaluate the non-inferiority of a zotarolimus-eluting stent (ZES; Endeavor Sprint®, n=80) to a sirolimus-eluting stent (SES; Cypher®, n=80) in patients with CTO lesion with a reference vessel diameter ≥2.5mm. The primary endpoint was in-segment binary restenosis rate at 9-month angiographic follow-up. Key secondary endpoints included target vessel failure (TVF; including cardiac death, myocardial infarction, and target vessel revascularization) and Academic Research Consortium-defined definite/probable stent thrombosis (ST) within 12 months. The ZES was non-inferior to the SES with respect to the primary endpoint, which occurred in 14.1% (95% confidence interval [CI]: 6.0-22.2) and in 13.7% (95%CI: 5.8-21.6) of patients, respectively (non-inferiority margin, 15.0%; P for non-inferiority <0.001). There were no significant between-group differences in the rate of TVF (10.0% vs. 17.5%; P=0.168) nor in the rate of ST (0.0% vs. 1.3%; P=0.316) during the 12-month clinical follow-up. Conclusions: The effectiveness and safety of ZES are similar to those of SES and therefore it is a good treatment option in patients undergoing PCI for CTO with DESs. (Circ J 2012; 76: 868-875)

Background:Little is known about subclinical atherosclerosis on coronary computed tomographic angiography (CCTA) in asymptomatic individuals with metabolic syndrome (MetS).Methods and Results:We analyzed 5,213 asymptomatic individuals who underwent CCTA. A cardiac event was defined as a composite of all-cause death, myocardial infarction, unstable angina, or coronary revascularization. Of the study participants, 2,042 (39.2%) had MetS. MetS was an independent predictor of significant coronary artery disease (CAD) in at least 1 coronary artery (odds ratio [OR]=1.992, 95% confidence interval [CI]=1.623–2.445, P<0.001) and significant CAD in the left main (LM) or proximal left anterior descending (LAD) artery (OR=2.151, 95% CI=1.523–3.037, P<0.001). During the follow-up period (median 28.1 [interquartile range, 19.2–36.5] months), 111 individuals had 114 cardiac events. Individuals with MetS were significantly associated with more cardiac events than those without (RR [rate ratio]=1.67, 95% CI=1.15–2.43, P=0.007). In the MetS group, individuals with significant CAD had the majority of cardiac events (RR=64.33, 95% CI=29.17–141.88, P<0.001). Furthermore, in the MetS with significant CAD group, those with significant CAD in the LM or proximal LAD had more cardiac events (RR=2.63, 95% CI=1.51–4.59, P=0.001).Conclusions:MetS was associated with subclinical atherosclerosis on CCTA with subsequent high risk for cardiac events. These findings suggest the importance of reducing unfavorable metabolic conditions in asymptomatic individuals.
