Abstract

Aims. This study was designed to investigate the predictive value of serum collagen biomarkers on the outcomes of acute ST-elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI). Methods. Two hundred and ten patients with STEMI were successfully treated with PCI within 6 hrs ofthe onset of chest pain. The levels of serum procollagen type I carboxyterminal peptide (PICP) and procollagen type III peptide (PIIINP) were measured by enzymelinked immunosorbent assay (ELISA) before, 3 and 6 months after PCI. Left ventricular ejection fraction was assessed by echocardiography at 3 and 6 months after PCI. The composite endpoints were death by any cause, recurrent myocardial infarction, heart failure or stroke. Results. At the end of the 12-month follow up, 29 patients (13.8%) experienced an end point. The level of serum PICP in patients with an end point was higher than in patients without an end point 7 days (19.45 ± 2.17 vs 14.95 ± 3.07 ng/ mL, P<0.05) or 3 month after the PCI (29.87 ± 3.02 vs 22.14 ± 3.33 ng/mL, P<0.05). The serum PIIINP level in patients with an end point was also higher than those without 7 days after PCI (59.34 ± 4.23 vs 48.78 ± 4.23 ng/mL, P<0.05). Multivariate logistic regression analysis showed day 7 (OR=2.170, 95% CI 1.583-4.345, P=0.01) and 3-month serum PICP (OR=2.340, 95% CI 1.431-4.650, P=0.01) were independent predictors of composite end points. Conclusions. Persistent elevation of serum collagen marker PICP three months after PCI predicts an adverse outcome for patients with acute ST-elevation myocardial infarction.
