BackgroundPulmonary hypertension (PH) and right ventricular (RV) dysfunction have been associated with adverse outcome in patients with chronic heart failure. However, data are lacking in the setting of acute decompensated heart failure (ADHF). We sought to determine prognostic significance of PH in patients with ADHF and its interaction with RV function.MethodsWe studied 326 patients with ADHF. Pulmonary artery systolic pressure (PASP) and RV function were determined with the use of Doppler echocardiography, with PH defined as PASP >50 mm Hg. The primary end point was all-cause mortality during 1-year follow-up.ResultsPH was present in 139 patients (42.6%) and RV dysfunction in 83 (25.5%). The majority of patients (70%) with RV dysfunction had PH. Compared with patients with normal RV function and without PH, the adjusted hazard ratio (HR) for mortality was 2.41 (95% confidence interval [CI] 1.44-4.03; P = .001) in patients with both RV dysfunction and PH. Patients with normal RV function and PH had an intermediate risk (adjusted HR 1.78, 95% CI 1.11-2.86; P = .016). Notably, patients with RV dysfunction without PH were not at increased risk for 1-year mortality (HR 1.04, 95% CI 0.43-2.41; P = .94). PH and RV function data resulted in a net reclassification improvement of 22.25% (95% CI 7.2%-37.8%; P = .004).ConclusionsPH and RV function provide incremental prognostic information in ADHF. The combination of PH and RV dysfunction is particularly ominous. Thus, the estimation of PASP may be warranted in the standard assessment of ADHF.Copyright © 2013 Elsevier Inc. All rights reserved.
