Who could benefit from this research

Could help

Adults with pulmonary arterial hypertension who meet study criteria and can participate in remote assessments.

Less likely to help

Some participants may not respond to carnitine or may experience no change in their symptoms.

What this research studies

People with PAH often develop right heart failure, which is a major cause of death. This study tests a simple, widely available supplement, carnitine, to see if it can improve right heart function and patient well-being. By using remote enrollment and outcome measurements, the trial aims to show whether carnitine can reduce lipotoxic stress in the right ventricle and enhance daily living. The team has preliminary data suggesting safety and potential benefit, and will randomize patients to carnitine or placebo for 12 weeks.

Why it matters

Potential benefit: If successful, patients may experience better heart function and improved quality of life with a safe, affordable supplement.

How similar studies have gone: Prior animal work and a small human pilot indicate safety and potential metabolic benefits, but larger trials are needed for definitive proof.
