Abstract
BACKGROUND: Recent studies in animal models and humans have shown that corin is critically involved in the regulation of salt-water balance, blood pressure, and cardiac function. OBJECTIVES: The goal of this study was to investigate the prognostic value of plasma soluble corin in patients with acute myocardial infarction (AMI). METHODS: We enrolled 1,382 consecutive AMI patients in a prospective cohort study and explored the association of plasma corin with AMI outcomes using multivariable Cox proportional hazards analysis. RESULTS: Patients with low corin levels were more likely to be female and to have histories of hypertension and heart failure (HF). Kaplan-Meier survival curves indicated that patients with corin levels above the median had a lower incidence of major adverse cardiac events (MACE) and all-cause mortality compared with those whose corin levels were below the median. Multivariate Cox regression analysis suggested that log corin was an independent predictor of MACE (hazard ratio [HR]: 0.61; 95% confidence interval [CI]: 0.42 to 0.96; p = 0.029), together with age, previous histories of AMI, HF, and diabetes, Killip class, percutaneous coronary intervention, coronary artery bypass graft, beta-blocker use, and log N-terminal pro-B-type natriuretic peptide. The C-statistic and integrated discrimination improvement for MACE were improved significantly by the addition of corin to the reference model. Moreover, log corin was also found to be a significant predictor of death (HR: 0.65; 95% CI: 0.41 to 0.97; p = 0.036) and HF hospitalization (HR: 0.48; 95% CI: 0.23 to 0.90; p = 0.009) after adjustment for clinical variables and established biomarkers of adverse prognosis. CONCLUSIONS: Our study demonstrates that corin is a valuable prognostic marker of MACE in patients with AMI, independent of established conventional risk factors.
