Background Cardiac rehabilitation programs, consisting of exercise training and disease management interventions, reduce morbidity and mortality after acute myocardial infarction. Objective In this pilot study, we aimed to developed and assess the feasibility of delivering a health watch–informed 12-week cardiac telerehabilitation program to acute myocardial infarction survivors who declined to participate in center-based cardiac rehabilitation. Methods We enrolled patients hospitalized after acute myocardial infarction at an academic medical center who were eligible for but declined to participate in center-based cardiac rehabilitation. Each participant underwent a baseline exercise stress test. Participants received a health watch, which monitored heart rate and physical activity, and a tablet computer with an app that displayed progress toward accomplishing weekly walking and exercise goals. Results were transmitted to a cardiac rehabilitation nurse via a secure connection. For 12 weeks, participants exercised at home and also participated in weekly phone counseling sessions with the nurse, who provided personalized cardiac rehabilitation solutions and standard cardiac rehabilitation education. We assessed usability of the system, adherence to weekly exercise and walking goals, counseling session attendance, and disease-specific quality of life. Results Of 18 participants (age: mean 59 years, SD 7) who completed the 12-week telerehabilitation program, 6 (33%) were women, and 6 (33%) had ST-elevation myocardial infarction. Participants wore the health watch for a median of 12.7 hours (IQR 11.1, 13.8) per day and completed a median of 86% of exercise goals. Participants, on average, walked 121 minutes per week (SD 175) and spent 189 minutes per week (SD 210) in their target exercise heart rate zone. Overall, participants found the system to be highly usable (System Usability Scale score: median 83, IQR 65, 100). Conclusions This pilot study established the feasibility of delivering cardiac telerehabilitation at home to acute myocardial infarction survivors via a health watch–based program and telephone counseling sessions. Usability and adherence to health watch use, exercise recommendations, and counseling sessions were high. Further studies are warranted to compare patient outcomes and health care resource utilization between center-based rehabilitation and telerehabilitation.

Background: External counterpulsation (ECP) is a noninvasive procedure using lower limbs pressure cuffs to improve coronary artery blood flow and offload the heart. There is currently no data on the effects of ECP among patients undergoing cardiac rehabilitation (CR). This pilot study aims to determine whether ECP improves exercise capacity among patients with heart failure or post acute myocardial infarction undergoing cardiac rehabilitation. Methods: This is a prospective randomised-controlled pilot study of the effect of ECP in patients with mild to moderate heart failure or post-acute myocardial infarction undergoing CR. Eligible patients were randomised at ratio of 1:1 to either combination of CR and ECP or CR only. All subjects received up to 16 sessions of conventional CR. For the combination arm, subjects received up to 16 one-hour sessions of one-hour ECP therapy following each CR session. All underwent baseline cardiopulmonary testing (CPET) and NT-Pro BNP determination and after completion of study. Results: A total of 4 patients were enrolled in the study from June 2016 to Jan 2017. Two were randomised to combination arm and two into CR arm. Post treatment VO2MAX improved 12 % in the combination arm (23.3±5.6 ml/min/kg from20.8±5.3 ml/min/kgat baseline) compare to 5% in the CR arm (23.0±6.2 ml/min/kg from21.9±2.3 ml/min/kg at baseline). There were no significant difference in the post treatment VO2MAX between groups, p=0.97. There was a 16% increased in post treatment maximum oxygen pulsein the combination group (14.4±1.0ml/beat from12.4±0.5ml/beat at baseline) compare to a 7.8% increased in the CR group (12.4±2.2ml/beat from11.5±1.4ml/beat at baseline). Interestingly, NT proBNP level worsened post treatment in the combination group (447.5±563.6 pre treatment to 472.7±560.5 post treatment), whereas improved in the CR only group (950.5±522.9 pre treatment to 327.5±202.6 post treatment). Conclusion: Cardiac Rehabilitation is known to improve exercise capacity among heart failure patients. ECP can further enhanced maximum oxygen consumption and maximum oxygen pulse in patients with mild to moderate degree of heart failure or post myocardial infarction undergoing cardiac rehabilitation. More studies with larger numbers are needed to prove this benefit of ECP.
