title: Prognostic value of tissue Doppler right ventricular systolic and diastolic function indexes combined with plasma B-type natriuretic Peptide in patients with advanced heart failure secondary to ischemic or idiopathic dilated cardiomyopathy.
abstract: Right ventricular (RV) dysfunction adversely affects prognosis in patients with chronic heart failure (CHF) due to left ventricular (LV) dysfunction. However, little evidence exists regarding the prognostic role of RV systolic and diastolic function indexes in combination with plasma B-type natriuretic peptide (BNP) in advanced CHF. Thus, 102 consecutive hospitalized patients with advanced CHF (New York Heart Association classes III to IV) due to LV systolic dysfunction (LV ejection fraction <35%) were studied by 2-dimensional conventional and tissue Doppler imaging (TDI) echocardiography of the left and right ventricles. Plasma BNP was also measured. Patients were followed for 6 months for major cardiovascular events (cardiovascular death and/or CHF-related hospitalization). During follow-up, 13 patients died and 63 patients reached the combined end point of cardiovascular death or CHF-related hospitalization. By univariate analysis, RV TDI systolic velocity, dilated cardiomyopathy, digoxin treatment (all p values <0.01), and female gender (p <0.05) were associated with increased cardiovascular death. Transmitral Doppler to mitral annular TDI early diastolic velocity ratio, RV TDI early diastolic velocity (p <0.05), and ratio of early to late RV diastolic TDI velocities (p <0.01) predicted the combined end point. In multivariate analysis, decreased RV systolic velocity, dilated cardiomyopathy, and female gender (all p values <0.05) were independent predictors of cardiovascular death, whereas increased ratio of early to late RV diastolic TDI velocities (p <0.01) and increased BNP (p <0.05) predicted the combined end point. In conclusion, RV TDI indexes combined with increased plasma BNP additively predict adverse cardiac outcomes in advanced CHF.
