title: The correlation between early complications of percutaneous coronary intervention and high sensitive C-reactive protein.
abstract: BACKGROUND
  Increased incidence of cardiovascular diseases, especially coronary artery disease (CAD), during recent decades shows this disease entity to be the leading cause of death in the world. On the other hand many successes were achieved in the treatment of these diseases with new technology, which has its own side effects and threats for the patient. Among these new strategies is percutaneous coronary intervention (PCI), especially with stent implantation. Although coronary stents are effective in the treatment of dissection and prevention of restenosis, many side effects and even death have been observed, from 5-10% per year. Some studies showed that there is a relation between high sensitivity C-reactive protein (hs-CRP), as a laboratory marker for early detection of thrombosis and/or restenosis, and early complications of percutaneous coronary intervention. The aim of this study is to evaluate hs-CRP level in patients after PCI and to investigate if this can be a prognostic value for detection of early complication.
  
  
  METHODS
  This is a descriptive, analytical study done in Shahid Chamran Hospital (Isfahan, Iran) in 2011-2012. 87 patients who had undergone PCI were studied. Their hs-CRP level was measured before and after the study. Moreover, early stent complications were detected during the first 24 hours after insertion. The data was recorded in a researcher-constructed checklist and analyzed by SPSS for Windows 20.
  
  
  RESULTS
  The mean ± SD of hs-CRP level in patients with and without complication were 1.36 ± 0.97 and 3.09 ± 1.8, respectively. According to Student's t-test, the hs-CRP level in patients with early complications was higher than patients without early complications of stent implantation; the difference was statistically significant (P < 0.001).
  
  
  CONCLUSIONS
  The hs-CRP serum concentrations of patients with, and without early stent complications were significantly different. According to the control diseases center (CDC) guideline, patients with a high level of hs-CRP need special care and attention.
