Could a simple bike ride predict heart failure in rare disease?

This study explored whether a heart scan performed during light exercise could spot early signs of heart strain in people with a rare genetic bleeding disorder (HHT) who also have liver complications. Researchers tested 47 adult patients to see if their lung blood pressure rose more during exercise than in healthy people, which might signal future heart problems. The goal was to find a better way to monitor these patients and potentially help them get a liver transplant sooner if needed.
