Clinical characteristics of coronary drug-eluting stent XXXX : insights from a two-center des registry.

Stent @entity174 (SF) has been implicated as a risk factor for in-stent @entity256 , but its incidence and clinical characteristics are not well established. Therefore we investigated the conditions associated with stent @entity174 and its clinical presentation and outcome. Between 2004 and 2007, consecutive cases of SF were collected from the Seoul National University Hospital. Clinical characteristics and outcome of @entity1 with @entity174 stents were compared with a ten-fold cohort of age and gender matched controls (n = 236). A total of 4,845 @entity1 received percutaneous coronary intervention and 3,315 @entity1 (68.4%) underwent angiographic follow-up. Twenty-eight @entity174 stents were observed in 24 @entity1 . The incidence of SF was 0.89% for @entity3446 -eluting stents (SES) and 0.09% for @entity1311 -eluting stents. @entity740 , stent implantation in the right coronary artery (RCA), and SES use were independent predictors of drug-eluting stent @entity174 by multivariate analysis. SF was significantly associated with binary @entity256 (11.4% vs 41.7%, P < 0.001) and increased risk of @entity75 revascularization (8.1% vs 33.3%, P = 0.001). @entity1 with SF but without significant @entity256 showed excellent outcome despite only medical treatment. In conclusion, SF is associated with increased rates of @entity256 and repeat revascularization. Significant risk factors include @entity740 , RCA intervention, and SES use.
