Background-Syndecan-1 is a member of the proteoglycan family involved in cell-matrix interactions. Experimental studies showed that syndecan-1 is associated with inflammation in acute myocardial infarction and remodeling. The goal of this study was to explore the role of syndecan-1 in human heart failure (HF).

Methods and Results-We analyzed plasma syndecan-1 levels in 567 patients with chronic HF. Primary end point was a composite of all-cause mortality and rehospitalization for HF at 18 months. Mean age was 71.0 +/- 11.0 years, 38% was women, and mean left ventricular ejection fraction was 32.5 +/- 14.0%. Median syndecan-1 levels were 20.1 ng/mL (interquartile range, 13.9-27.7 ng/mL). Patients with higher syndecan-1 levels were more often men, had higher N-terminal probrain-type natriuretic peptide levels, and worse renal function. Multivariable regression analyses showed a positive correlation between syndecan-1 levels and markers of fibrosis and remodeling but no correlation with inflammation markers. Interaction analysis revealed an interaction between left ventricular ejection fraction and syndecan-1 (P=0.047). A doubling of syndecan-1 was associated with an increased risk of the primary outcome in patients with HF with preserved ejection fraction (hazard ratio, 2.10; 95% confidence interval, 1.14-3.86; P=0.017) but not in patients with HF with reduced ejection fraction (hazard ratio, 0.95; 95% confidence interval, 0.71-1.27; P=0.729). Finally, syndecan-1 enhanced risk classification in patients with HF with preserved ejection fraction when added to a prediction model with established risk factors.

Conclusions-In patients with HF, syndecan-1 levels correlate with fibrosis biomarkers pointing toward a role in cardiac remodeling. Syndecan-1 was associated with clinical outcome in patients with HF with preserved ejection fraction but not in patients with HF with reduced ejection fraction.
