Abstract | BACKGROUND: METHODS AND RESULTS: In 126 patients with chronic systolic heart failure (left ventricular ejection fraction <or=35%, New York Heart Association functional Class I-IV), we measured plasma corin and natriuretic peptide levels and performed comprehensive echocardiography with assessment of cardiac structure and performance. Adverse clinical events (all-cause mortality, cardiac transplantation, or heart failure hospitalization) were prospectively tracked for a median of 38 months. Plasma corin levels modestly correlated with echocardiographic indices of cardiac structure, including left ventricular mass index (r = 0.30, P = .003) and interventricular septum width (r = 0.22, P = .013). However, plasma corin levels did not correlate with age, arterial pressures, estimated glomerular filtration rate, echocardiographic indices of systolic or diastolic function, or plasma natriuretic peptide levels. In Cox proportional hazards analysis, higher plasma corin levels did not predict reduced risk of adverse clinical events (hazard ratio 0.91; 95% confidence interval 0.67-1.24, P = .52), and did not provide incremental prognostic value to natriuretic peptide levels. CONCLUSION:
