Effectiveness of Remote Cardiac Rehab After Surgery for Acquired Heart Valve Disease

"The patient, following heart valve surgery, is undergoing home-based cardiovascular rehabilitation during the late recovery phase. The rehabilitation is remotely supervised by a therapist through the Open TeleRehab software and includes aerobic exercises, breathing exercises, and lower limb resistance training.~* Aerobic exercise: Performed 3 times per week, each session lasting 20-40 minutes. Activities include walking, stair climbing, or cycling. Exercise intensity is determined based on:~ 1. Target heart rate: Set at the anaerobic threshold identified through Cardiopulmonary Exercise Testing (CPET) prior to hospital discharge; heart rate is monitored using a handheld pulse oximeter.~ 2. Borg Rating of Perceived Exertion (RPE) scale for dyspnea: maintained at 12-13 out of 20.~* Lower limb resistance training: Performed 3 times per week, each session lasting 30-40 minutes. Intensity is based on the one-repetition maximum (1RM).~* Breathing exercises: Performed 3 times per week"

"After completing inpatient rehabilitation, patients are discharged and continue supervised outpatient rehabilitation three times per week. The program includes aerobic exercise, lower limb resistance training, and breathing exercises.~Aerobic exercise: Each session lasts 20-40 minutes, depending on the patient's condition, and is performed using a Cardiopulmonary Exercise Testing (CPET) device. Exercise intensity is determined based on the target heart rate and the Borg Rating of Perceived Exertion (RPE) scale for dyspnea and fatigue, in accordance with the 2021 guidelines of the Japanese Circulation Society.~Lower limb resistance training: Each session lasts 30-40 minutes.~Breathing exercises: Each session lasts 15-20 minutes"
