Heart Failure & Pulmonary Hypertension (Part II)
- HFpEF-PH management guidelines recommend the treatment of symptoms of congestion and volume overload, targeting LV relaxation and co-morbidities; including the management of pulmonary congestion, ischemia, sleep apnea, atrial fibrillation, and diabetes.
- Both atrial/ventricular dysrhythmias contribute to the mortality associated with HF & control of particularly atrial fibrillation, is an essential part of the early pulmonary vascular remodeling process.
- Both endothelin receptor antagonists (ERA) and prostanoids have been effective for PAH & clinical trials utilizing these agents have also been attempted in treatment of PH due to left heart disease, but have proven to be either neutral or even detrimental.
- Selective dilation of the pulmonary vessels in patients with postcapillary PH, without simultaneously ensuring the unloading of the LV, can cause profound pulmonary venous congestion resulting in sudden pulmonary edema, which greatly increases the morbidity in patients with this form of PH.
- Currently, the most compelling published data for pharmacological treatment targeting PH in HFpEF involves phosphodiesterase (PDE) inhibitor sildenafil.
