Conventional Cardiac Rehabilitation
Both the remote technology intervention and reference groups received conventional cardiac rehabilitation. The initiation of the intervention included a 5-day in-rehabilitation period. Furthermore, 2 follow-up periods of 5 days at the 6- and 12-month time points in the rehabilitation center were included in the study (The researchers at the University of Jyväskylä, Finland, were in equal contact with the rehabilitees in the remote technology intervention and reference groups during the different phases of the study. Furthermore, intervention, initiation, and follow-up periods in the remote technology intervention and reference groups were equal in the time sequence of the rehabilitation stages.
