Abstract:

Objective To investigate the predictive value of D-dimer combined with cystatin C level in the occurrence of major adverse cardiovascular event(MACE) in the patients with acute myocardial infarction. Methods From January 2014 to December 2017, 287 patients with acute myocardial infarction who received undergoing percutaneous coronary intervention (PCI) were selected. According to the median levels of serum D-dimer and cystatin C after admission, the patients were divided into four groups, group 1: D-dimer<0.33 mg/L, cystatin C<1.06 mg/L; group 2: D-dimer<0.33 mg/L, cystatin C≥1.06 mg/L; group 3: D-dimer≥0.33 mg/L, cystatin C<1.06 mg / L; group 4: D-dimer≥0.33 mg/L, cystatin C≥1.06 mg/L. The multivariate Cox regression analysis was used to analyze the value of D-dimer combined with cystatin C level in predicting the occurrence of MACE. Results The median time of follow up was 2.89 years. The multivariate Cox regression analysis showed that, the incidence of MACE was significantly increased in the group with high D-dimer and cystatin C levels [hazard ratio (HR)=2.71, 95% confidence interval (CI): 1.37-5.36, P<0.01] after adjustment of age, gender and traditional risk factors. Conclusions The D-dimer combined with cystatin C can effectively predict the occurrence of MACE in the patients with acute myocardial infarction undergoing PCI.
