Summary

This trial will test whether diet and exercise can help improve Pulmonary Arterial Hypertension by affecting insulin sensitivity.

Who is the study for?
This trial is for adults aged 18-75 with Group 1 Pulmonary Arterial Hypertension (PAH), including various subtypes, who are stable on current medications. It's not suitable for those with severe PAH symptoms, diabetes, heart issues like ischemia or uncontrolled arrhythmias, high oxygen needs (>4 LPM), recent fainting episodes, or other specific lung and systemic diseases.
What is being tested?
The PHINE study is testing whether a special diet and exercise program can improve the health of people with PAH by helping their bodies use insulin better. The idea is that changing how the body handles sugar might help ease the strain on blood vessels in the lungs.
What are the potential side effects?
While this trial focuses on nutrition and exercise which typically have positive effects on health, potential side effects may include muscle soreness from physical activity and changes in digestion or appetite due to new dietary habits.
