Abstract

IntroductionCardiovascular diseases are the leading cause of death worldwide and are partly caused by modifiable risk factors. Cardiac rehabilitation addresses several of these modifiable risk factors, such as physical inactivity and reduced exercise capacity. However, despite its proven short-term merits, long-term adherence to healthy lifestyle changes is disappointing. With regards to exercise training, it has been shown that rehabilitation supplemented by a) home-based exercise training and b) supportive digital tools can improve adherence.MethodsIn our multi-center study (ClincalTrials.gov Identifier: NCT04458727), we analyzed the effect of supportive digital tools like digital diaries and/or wearables such as smart watches, activity trackers, etc. on exercise capacity during cardiac rehabilitation. Patients after completion of phase III out-patient cardiac rehabilitation, which included a 3 to 6-months lasting home-training phase, were recruited in five cardiac rehabilitation centers in Austria. Retrospective rehabilitation data were analyzed, and additional data were generated via patient questionnaires.Results107 patients who did not use supportive tools and 50 patients using supportive tools were recruited. Already prior to phase III rehabilitation, patients with supportive tools showed higher exercise capacity (Pmax = 186 ± 53 W) as compared to patients without supportive tools (142 ± 41 W, p

Abstract

In patients with coronary heart disease, both arterial stiffness and wave reflections are increased and predict unfavorable cardiovascular events. Cardiac rehabilitation has the goal to reduce risk factors and slow the progression of the disease. The aim of this study was to prospectively determine the impact of an ambulatory cardiac rehabilitation program on pulsatile hemodynamics. Male patients after coronary interventions, bypass surgery, or acute coronary syndromes underwent exercise and resistance training. Before and after the program, pulsatile hemodynamics was measured. Exercise capacity was assessed with an incremental cycle ergometer protocol. A detailed two-dimensional and Doppler echocardiogram was obtained for systolic and diastolic left ventricular function. A total of 27 men participated in the study. After the intervention (n = 24), carotid–femoral pulse wave velocity decreased significantly from 8.7 (standard deviation (SD): 1.7) to 7.9 (SD: 1.9) m/s (p = 0.019), and augmentation index normalized for a heart rate of 75/min decreased significantly from 20.4 (SD: 8.7) to 17.5 (SD: 8.1; p = 0.017). The results suggest that a structured ambulatory rehabilitation program may improve pulsatile hemodynamics in coronary artery disease (CAD) patients.
