title: Evidence of pre-procedural statin therapy a meta-analysis of randomized trials.
abstract: OBJECTIVE
  The purpose of this study was to summarize the evidence of pre-procedural statin therapy to reduce periprocedure cardiovascular events.
  
  
  BACKGROUND
  Invasive procedures can result in adverse cardiovascular events, such as myocardial infarction (MI) and death. We hypothesized that statins might improve clinical outcomes when used before invasive procedures.
  
  
  METHODS
  We searched the MEDLINE, Cochrane, and clinicaltrials.gov databases from inception to February 2010 for randomized, controlled trials that examined statin therapy before invasive procedures. Invasive procedures were defined as percutaneous coronary intervention, coronary artery bypass grafting (CABG), and noncardiac surgery. We required that studies initiated statins before the procedure and reported clinical outcomes. A DerSimonian-Laird model was used to construct random-effects summary risk ratios.
  
  
  RESULTS
  Eight percent of the screened trials (21 of 270) met our selection criteria, which included 4,805 patients. The use of pre-procedural statins significantly reduced post-procedural MI (risk ratio [RR]: 0.57, 95% confidence interval [CI]: 0.46 to 0.70, p < 0.0001). This benefit was seen after both percutaneous coronary intervention (p < 0.0001) and noncardiac surgical procedures (p = 0.004), but not CABG (p = 0.40). All-cause mortality was nonsignificantly reduced by statin therapy (RR: 0.66, 95% CI: 0.37 to 1.17, p = 0.15). Pre-procedural statins also reduced post-CABG atrial fibrillation (RR: 0.54, 95% CI: 0.43 to 0.68, p < 0.0001).
  
  
  CONCLUSIONS
  Statins administered before invasive procedures significantly reduce the hazard of post-procedural MI. Additionally, statins reduce the risk of atrial fibrillation after CABG. The routine use of statins before invasive procedures should be considered.
