Pulmonary arterial hypertension (PAH) is a chronic, progressive disease that is incurable, even with effective therapy. Long-term outcome in PAH is best preserved by targeting hemodynamic improvements to reduce risk of subsequent right ventricular (RV) failure. Methods that can assess RV adaptation to stress have important implications to better understand an individual's physiology and may play a pivotal role in guiding therapy in PAH. In this novel pilot study, we evaluate the feasibility of monitoring hemodynamic response to 6-minute walk distance in patients with PAH using the CardioMEMS HF System.
