Abstract

Urotensin II (UII) is a potent vasoactive cyclic peptide thought to play a role in myocardial hypertrophy and remodelling. We therefore determined UII plasma levels in congestive heart failure (CHF) patients and its relationship with the severity of the disease and well-established markers of left ventricular function. UII was significantly higher in CHF patients (n = 57) than in controls (n = 48) [geometric mean (pg/ml), 95% PI: 1.32 (0.67-2.59) versus 0.84 (0.31-1.61), p < 0.0001], was related to the functional class of the disease and correlated negatively with left ventricular ejection fraction (r = -0.316, P = 0.016). Furthermore, UII correlated significantly with Big-ET1 (r = 0.32, p = 0.03), BNP (r = 0.42, p = 0.005) but poorly with Nt-proANP (r = 0.28, p = 0.07). Our results suggest that UII could play a role in worsening the course of congestive heart failure and is associated with established markers of cardiovascular dysfunction.
