Effects of Heart Rate Fluctuation on Aerobic Training Outcomes in Patients With Stable Coronary Artery Disease: A Prospective Study

Exercise rehabilitation with different training regimens can enhance cardiac function in patients with CAD. Different heart rate modulation strategies yielded distinct effects on cardiopulmonary function. Maintenance of a narrower heart rate fluctuation during exercise was observed to significantly enhance the effectiveness of rehabilitation, which could lead to new treatment protocols or optimization of existing strategies for patients with cardiovascular conditions. The combination of 6MWT and power bicycle training may offer an effective method for improving cardiac function in community-based rehabilitation settings.
