title: Effect of primary percutaneous coronary intervention on serum collagen biomarkers following acute myocardial infarction.
abstract: OBJECTIVE
  The aim of this study was to investigate the effect of primary percutaneous coronary intervention (PCI) on serum collagen biomarkers following acute myocardial infarction (AMI).
  
  
  RESULTS
  Thirty-eight patients were enrolled into a primary PCI (n = 16) and a control (n = 22) group. The PCI group received successful PCI within 6 h of MI, whereas the control group received no PCI or thrombolytic therapy. Serum type I procollagen (PICP) and type III procollagen (PIIINP) were measured by enzyme-linked immunosorbent assay (ELISA). The baseline characteristics were similar between the PCI and control groups. There was no significant difference in left ventricular end-systolic, end-diastolic volume or ejection fraction between the two groups 30 min after MI (P > 0.05). A significant increase in PICP and PIIINP was noted in both groups 3 days after MI (P < 0.01). PICP and PIIINP in the PCI group declined overtime to the pre-PCI level, whereas they remained high in the control group. In the PCI group, the mean serum PICP and PIIINP on day 7, 14 and 30 was lower than in the control group (P < 0.01).
  
  
  CONCLUSIONS
  AMI is associated with an increase in serum biomarkers of collagen synthesis. Early and successful PCI is associated with a reduction in serum collagen biomarkers.
