Session Title: Pulmonary Hypertension Prognosis/Outcomes Abstract Category: 30. Pulmonary Hypertension Presentation Number: 1131-546 Authors: Thenappan Thenappan, Sanjiv Shah, Stuart Rich, University of Chicago Medical Center, Chicago, IL, USA Background: Pulmonary hypertension associated with heart failure with preserved ejection fraction (PH-HFpEF) is an increasingly common cause of PH. The long-term survival of patients with PH-HFpEF is unknown. We performed an observational study to determine survival in patients with PHHFpEF and to compare it with patients with WHO group 1 pulmonary arterial hypertension (PAH). Methods: We included consecutive patients with PH-HFpEF (n=100) and PAH (n=558) referred to our center from 1982-2009. Vital statistics were obtained by chart review and social security death index. We used Kaplan-Meier method and Cox proportional hazard analysis to determine survival and independent predictors of mortality. Results: Patients with PH-HFpEF were older, had a higher prevalence of cardiovascular comorbidities, had worse exercise capacity and renal function. PH was less severe in PH-HFpEF patients than in PAH patients (pulmonary vascular resistance 4.8 vs. 10.9 Wood units; P<0.001). The median observation time was 7.8 yrs. The 1-, 3-, and 5-year survival for patients with PH-HFpEF was 96%, 84%, and 75% respectively. PH-HFpEF had a worse survival compared to PAH (unadjusted HR: 0.42; 95%CI 0.31-0.57; P<0.001) that was not related to age (age adjusted HR 0.68 95% CI 0.48 - 0.96; P=0.02) (Fig 1). Conclusion: The survival of patients with PH-HFpEF is worse than those with PAH despite having less severe PH.
