New exercise sequence aims to boost strength and stamina in heart patients

This study tests a new exercise program called PREACTIVE for people aged 60 and older who have both atrial fibrillation (an irregular heartbeat) and a type of heart failure called HFpEF. The program starts with resistance training (like lifting weights) to build muscle, then adds aerobic exercise (like walking). The goal is to see if this approach improves symptoms, quality of life, and the ability to do daily activities. Thirty participants will be enrolled at Northwestern University.
