Abstract
BACKGROUND: Admission for an acute heart failure (HF) confers an extremely poor prognosis. We aimed at finding out whether simultaneous assessment of multiple plasma-based biomarkers and Doppler echocardiography could provide complementary information and thus enable clinicians to stratify risk more effectively among patients hospitalized with acute HF; hence, untoward events after discharge avoided. METHODS: A comprehensive echocardiographic study and measurements of cardiac troponin I (cTnI), N-terminal pro-B-type natriuretic protein (NT-proBNP), and high-sensitivity C-reactive protein (hsCRP) were conducted in 87 patients with symptomatic de novo acute HF or decompensation of chronic HF. Major adverse cardiac events (MACE) regarding cardiac death or hospitalization with worsening HF during a median follow-up period of 191 days were determined. RESULTS: According to the univariate analysis, echocardiographic variables left atrial volume, left atrial volume index, pulmonary artery systolic pressure, E/E' ratio, and the concentrations of NT-proBNP were significantly related to clinical outcomes (all P-values < 0.05). Cox proportional hazard analysis identified two independent prognostic predictors of MACE: E/E' ratio and NT-proBNP. Moreover, the combining of plasma level of NT-proBNP with E/E' ratio provided independent and additional prognostic value in identifying high-risk acute HF patients. CONCLUSIONS: These findings reinforce the necessity of combining the heart hemodynamic variable E/E' ratio and plasma-based neurohormonal biomarker NT-proBNP when clinicians attempt to define the individual risk of patients hospitalized with acute HF.
