Abstract:
BACKGROUND:The introduction of drug-eluting stents (DES) dramatically changed the practice of percutaneous coronary intervention (PCI) in the 2000s. Little is known about trends in in-hospital outcome after PCI in the DES era. HYPOTHESIS:The in-hospital outcomes after PCI might be continuously improved over time. METHODS:We analyzed in-hospital outcomes of 21,667 patients who underwent PCI at Fu Wai Hospital in the past 5 years. The patients were divided into 5 groups according to the time of their intervention: group 1 (June 2004 to May 2005), group 2 (June 2005 to May 2006), group 3 (June 2006 to May 2007), group 4 (June 2007 to May 2008), and group 5 (June 2008 to May 2009). RESULTS:Procedural success rates for the 5 groups were 93.6%, 95%, 94.4%, 94.2%, and 94.3%, respectively (P = 0.39). Significant reduction in in-hospital major adverse cardiac events (3.1%, 3.4%, 2.8%, 1.6%, and 1.0%, P < 0.001) and need for target-vessel revascularization (2.0%, 2.2%, 1.5%, 0.4%, and 0.2%, P < 0.001) was noted over time, which was associated with a significant increase in use of DES (from 56.6% to 97.0%, P < 0.001). On multivariate analysis, use of DES, dissection during procedure, left main lesion, prior myocardial infarction, and age > or = 65 years were independent predictors of major adverse cardiovascular events. CONCLUSIONS:There were substantial reductions in in-hospital major adverse cardiac events and target-vessel revascularization over the past 5 years. This reduction was associated with the concurrent increased use of DES.
