Telerehabilitation after acute coronary syndrome warrants a similar improvement in physical performance as stationary rehabilitation regardless of the age profile of the compared groups

Abstract

Abstract During the COVID-19 pandemic, the availability of cardiac rehabilitation (CR) was limited. On the other hand, during the epidemic hazard period, patients after acute coronary syndromes (ACS) required careful control and ensuring their improvement after the coronary event. The aim of this study was to assess whether CR conducted during the epidemic threat in remote mode ensures similar improvement in physical performance as rehabilitation conducted in stationary mode before the pandemic COVID-19. Material and methods In this one-center study, the demographic and clinical profiles in the groups of patients after ACS who completed a stationary CR before COVID-19 era or telerehabilitation during the COVID-19 pandemic were compared. The workload on the initial and final exercise tests (ExT) obtained by patients was assessed, as well as the values of differences between the final and initial ExT were compared. 359 patients (pts) participating in stationary CR before October 2020 and 60 pts - in telerehabilitation after July 2021 were included. Both, stationary and tele- CR were performed according to the guidelines of Working Group for Cardiac Rehabilitation of the national cardiac society. Telemedic platform was used to control ECG, blood pressure and body mass of pts participating in telerehabilitation. Statistical analysis included U Mann-Whitney test, T Student test and chi square test. Results The improvment of physical performance did not differ significantly between both groups. The pts who completed telerehabilitation were significantly older than those who completed stationary CR. The values of other parameter, like percent of females, BMI, percent of pts with arterial hypertension and diabetes mellitus type 2 or ejection fraction of left ventricle did not differ significanty between compared groups. The results of statistical analysis are presented in the table below. Conclusions In our center, telerehabilitation after acute coronary syndrome guaranteed an equally good improvement in physical capacity, which was observed in stationary rehabilitation patients, regardless of the difference in the age profile of the compared groups. These results encourage popularization of the cardiac rehabilitation mode with the remote control of the ECG, blood pressure and body weight.Comparison of the study groups
