- W2055557680 abstract "<h3>Background</h3> Pulmonary hypertension (PH) associated with left heart disease (World Health Organization [WHO] Group II) has previously been linked with significant morbidity and mortality. However, there are currently no approved therapies or hemodynamic monitoring systems to improve outcomes in WHO Group II PH. <h3>Methods</h3> We conducted a retrospective analysis of the CHAMPION trial of an implantable hemodynamic monitor (IHM) in 550 New York Heart Association (NYHA) Functional Class III HF patients, regardless of left ventricular ejection fraction (LVEF) or heart failure (HF) etiology. We evaluated clinical variables, changes in medical therapy, HF hospitalization rates and survival in patients with and without WHO Group II PH. <h3>Results</h3> Data were obtained for 314 patients (59%) who had WHO Group II PH. Patients without PH were at significantly lower risk for mortality than PH patients (hazard ratio [HR] 0.31, 95% confidence interval [CI] 0.19 to 0.52, <i>p</i> < 0.0001). PH patients had higher HF hospitalization rates than non-PH patients (0.77/year vs 0.37/year; HR 0.49, 95% CI 0.39 to 0.61, <i>p</i> < 0.001). In patients with and without PH, ongoing knowledge of hemodynamic data resulted in a reduction in HF hospitalization for PH patients (HR 0.64, 95% CI 0.51 to 0.81, <i>p</i> = 0.002) and for non-PH patients (HR 0.60, 95% CI 0.41 to 0.89, <i>p</i> = 0.01). Among PH patients, there was a reduction in the composite end-point of death and HF hospitalization with ongoing knowledge of hemodynamics (HR 0.74, 95% CI 0.55 to 0.99, <i>p</i> = 0.04), but no difference in survival (HR 0.78, 95% CI 0.50 to 1.22, <i>p</i> = 0.28). <h3>Conclusions</h3> WHO Group II PH is prevalent and identifies HF patients at risk for adverse outcomes. Ongoing knowledge of hemodynamic variables may allow for more effective treatment strategies to reduce the morbidity of this disease." @default.
