Summary
This study tests whether a personalized high-intensity interval training (HIIT) program can improve exercise capacity and quality of life in people with heart failure with preserved ejection fraction (HFpEF). Participants are randomly assigned to either a 24-week HIIT plan tailored to their fitness test results or to standard care. The main goal is to measure changes in peak oxygen consumption, a key marker of heart and lung fitness.
