Plasma connective tissue growth factor is a novel potential biomarker of cardiac dysfunction in patients with chronic heart failure.

Abstract

BACKGROUND:

Connective tissue growth factor (CTGF) has been recently reported as a mediator of myocardial fibrosis; however, the significance of plasma CTGF concentration has not been evaluated in patients with heart failure. The aim of this study was to investigate the clinical utility of plasma CTGF concentration for the diagnosis of heart failure.

METHODS AND RESULTS:

We evaluated fifty-two patients with chronic heart failure. The plasma concentration of CTGF and other markers of fibrosis were assessed and compared with clinical and echocardiographic data. Plasma CTGF was significantly elevated in symptomatic patients in proportion to their NYHA classes and was significantly correlated with plasma brain natriuretic peptide (BNP) concentration (r=0.395, P<0.01). Plasma CTGF was also correlated with plasma transforming growth factor beta (TGF-beta) (r=0.512, P<0.01), matrix metalloproteinase (MMP)-2 (r=0.391, P<0.05) and tissue inhibitor of MMP (TIMP)-2 (r=0.354, P<0.05) concentrations. Interestingly, plasma CTGF was correlated with E/E' value evaluated by tissue Doppler echocardiography (r=0.593, P=0.012), but not with systolic function and left ventricular mass.

CONCLUSION:

Our study suggests that plasma CTGF concentration is a novel diagnostic marker for cardiac dysfunction and may provide additional specific information about myocardial fibrosis in chronic heart failure patients.
