title: Associated factors with repeat coronary angioplasty during the drug eluting stent era: a high volume center investigation.
abstract: BACKGROUND
  Repeat percutaneous coronary intervention (PCI) is associated with unfavorable prognosis in patients with coronary artery disease, but there is a current lack of related systematic cross-sectional studies in China. The survey was to investigate a real world of repeat PCIs and their associated factors during the drug eluting stent era in a Beijing high volume center.
  
  
  METHODS
  A comprehensive review of the institution's database between January 2006 and July 2009 was conducted. Demographic information, concomitant diseases, peri-procedure laboratory examinations and angiographic features were collected consecutively. Multivariate Logistic regression analysis was undertaken to explore the risk factors associated with repeat PCIs.
  
  
  RESULTS
  A total of 13 404 patients were included in the analysis. Of which, 1946 patients (14.5%) had prior PCI procedure. More males patients had previous PCI than the females (15.7% vs 10.9%, P < 0.001). After adjustment for age, gender, concomitant diseases, angiographic and procedural factors, a multivariate model showed that male, diabetes, hyperlipidemia and previous myocardial infarction, left main disease were identified as independent risk factors of repeat PCIs. Of which, previous myocardial infarction (odds ratio: 2.58, 95% confidence interval: 2.27 - 2.92) was highly related with repeat PCIs.
  
  
  CONCLUSIONS
  The frequency of repeat PCIs was 14.5% in this cross-sectional investigation, and their associated factors included male, diabetes, hyperlipidemia and previous MI and left main disease during drug eluting stent era.
