    Abstract:
    OBJECTIVE: To investigate the changes of plasma urotensinII (UII) levels in patients with congestive heart failure (CHF) of different severities and their clinical implications. METHODS: Plasma UII was determined by radioimmunoassay in 45 patients with CHF and 20 healthies control subjects. In all the subjects, the left ventricular fraction (LVEF) and the ratio of E/A were measured by echocardiography. RESULTS: The plasma UII level was significantly lowered in CHF patients in comparison with that in control subjects (1.41+/-1.09 pg/ml vs 4.35+/-1.22 pg/ml, P=0.000). A significant correlation of plasma UII level with LVEF (r=0.540, P=0.000) and the E/A ratio was observed (r=0.539, P=0.000), and the severity of CHF was shown to be inversely correlated with plasma UII levels in the patients (r=-0.656, P=0.000), which was elevated after treatment. CONCLUSION: UII might play a role in the pathophysiological process of CHF, and its plasma level may serve as an indicator of the severity of CHF.
