After unrestricted use of second-generation drug-eluting stents in all-comers receiving percutaneous coronary intervention, both EES and ZES showed comparable clinical outcomes in the patients with DM up to 1 year of follow-up. DM compared with non-DM patients showed significantly worse patient- and stent-related outcomes. Nonetheless, overall incidences of TLF were low, even in the patients with DM, suggesting excellent safety and efficacy of both types of second-generation drug-eluting stents in this high-risk subgroup of patients.
At 1 year, PtCr-EES was noninferior to CoCr-ZES in all-comers receiving PCI. Although LSD was observed only in PtCr-EES, both the stent length ratio and the frequency of LSD were not significantly different between the 2 stent types, and PtCr-EES was not associated with adverse clinical outcomes.

We sought to determine the prevalence of metabolic syndrome (MS) in patients with acute myocardial infarction and its effect on clinical outcomes. Employing data from the Korea Acute Myocardial Infarction Registry, a total of 1,990 patients suffered from acute ST-elevation myocardial infarction (STEMI) between November 2005 and December 2006 were categorized according to the National Cholesterol Education Program-Adult Treatment Panel III criteria of MS. Primary study outcomes included major adverse cardiac events (MACE) during one-year follow-up. Patients were grouped based on existence of MS: group I: MS (n=1,182, 777 men, 62.8±12.3 yr); group II: Non-MS (n=808, 675 men, 64.2±13.1 yr). Group I showed lower left ventricular ejection fraction (LVEF) (P=0.005). There were no differences between two groups in the coronary angiographic findings except for multivessel involvement (P=0.01). The incidence of in-hospital death was higher in group I than in group II (P=0.047), but the rates of composite MACE during one-year clinical follow-up showed no significant differences. Multivariate analysis showed that low LVEF, old age, MS, low high density lipoprotein cholesterol and multivessel involvement were associated with high in-hospital death rate. In conclusion, MS is an important predictor for in-hospital death in patients with STEMI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
