Abstract
BACKGROUND: Pulmonary hypertension (PH) is present in over two-thirds of patients who experience heart failure with preserved ejection fraction (HFpEF), and it worsens their prognosis, particularly when combined with right ventricular dysfunction. Effective treatments for HFpEF-related PH are limited. CASE SUMMARY: A 70-year-old woman presented with severe exertional dyspnea and hypoxia. Echocardiography revealed a preserved ejection fraction with advanced diastolic dysfunction, as well as severe PH. Right heart catheterization showed pulmonary pressures at systemic levels and elevated left-sided filling pressures. Significant symptom improvement and normalized pulmonary pressures were noted after treatment with sacubitril-valsartan and a sodium-glucose cotransporter 2 (SGLT2) inhibitor. DISCUSSION: Although sacubitril-valsartan and SGLT2 inhibitors have been proven effective in HFpEF, their specific role in HFpEF-PH remains unclear. This case highlights their potential to improve hemodynamics and symptoms in this challenging patient population. TAKE-HOME MESSAGE: Sacubitril-valsartan and SGLT2 inhibitors may be effective for treating PH in HFpEF; further investigation is warranted.
