Abstract 9658: Generation Differences in Long-Term Clinical Outcomes in Diabetic Patients After PCI Across POBA-, BMS- and DES-Era

Abstract

Introduction: PCI has evolved with technological advance, improvement of operators’ techniques and medical therapy for secondary prevention. Despite these improvements, diabetes remains a negative predictor. To date, little is known regarding improvement of clinical outcomes in diabetic patients with PCI. We examined a temporal trend of long-term clinical outcomes in diabetic cohort across the different generations. Hypothesis: We hypothesized that clinical outcomes would improve with advances of PCI. Methods: We analyzed data of diabetic patients with PCI in Juntendo University from 1984 to 2010. The patients were divided into three groups according to the procedure data (POBA-era; January 1984 - December 1997, BMS-era; January 1998 - July 2004 and DES-era; August 2004 - February 2010). Primary endpoint was a composite of major adverse cardiovascular events including all-cause mortality, non-fatal myocardial infarction, non-fatal stroke and revascularization. Results: A total of 1544 patients were examined (POBA-era; 374, BMS-era; 494 and DES-era; 676). The mean age was higher in DES-era. A higher prevalence of hypertension and dyslipidemia was observed in DES-era. The success rate of PCI was lower among the patients in POBA-era. Kaplan-Meier estimation for 3-year MACE was significantly different among the eras (Figure 1). Multivariable Cox regression analysis showed that DES-era was a predictor for long-term MACE (DES- vs BMS era; HR 0.50, 95%, CI 0.38 - 0.66, P < 0.001, DES- vs POBA-era; HR 1.60, 95% CI 0.34-27.9, P = 0.6). Conclusions: Long-term clinical outcomes in diabetic patients who underwent PCI were more favorable in DES-era, despite the higher risk profiles.
