BACKGROUND: In patients with heart failure, pulmonary hypertension (PH) predicts higher risk for morbidity and mortality. However, few data are available on the prognostic implications of reactive (precapillary) PH superimposed on passive (postcapillary) PH.
METHODS AND RESULTS: We performed a subgroup analysis of 242 patients with acute decompensated heart failure assigned to pulmonary artery catheter placement in the Vasodilation in the Management of Acute Congestive Heart Failure trial. Patients were classified into 3 groups, using the final (posttreatment) hemodynamic measurements: (1) no PH (mean pulmonary artery pressure ≤ 25 mm Hg; (2) passive PH (mean pulmonary artery pressure > 25, pulmonary capillary wedge pressure >15 mm Hg, and pulmonary vascular resistance ≤ [corrected] Wood units); and (3) reactive PH (mean pulmonary artery pressure > 25, [corrected] pulmonary capillary wedge pressure >15 mm Hg, and pulmonary vascular resistance > 3 Wood units). Fifty-eight patients were classified as normal mean pulmonary artery pressure, 124 with passive PH and 60 with reactive PH. During follow-up of 6 months, 5 (8.6%), 27 (21.8%), and 29 (48.3%) deaths occurred in patients without PH, patients with passive PH, and with reactive PH, respectively (P<0.0001). After multivariable adjustments, reactive PH remained an independent predictor of death, with an adjusted hazard ratio of 4.8 compared with patients without PH, and 2.8 compared with patients with passive PH (95% confidence interval, 1.7 to 4.7, P=0.0001). Similar results were obtained when reactive PH was defined on the basis of transpulmonary gradient.
CONCLUSIONS: Reactive PH is common among patients with acute decompensated heart failure after initial diuretic and vasodilator therapy. The adverse outcome associated with PH is predominantly due to increased mortality rates in the subgroup of patients with reactive PH.
