1, To investigate whether OHCA-survivors have lower levels of self-reported physical activity compared to a non-cardiac arrest control group of myocardial infarction (MI) patients, and explore the association to selected variables assumed important for decreased physical activity.
2, To investigate the relationship between self-reported and objectively measured physical activity among OHCA-survivors.
This study will be performed as a sub-study of the TTM2-trial, where all OHCA-survivors are invited to a structured face-to-face follow-up 6-months post-OHCA. At time of this follow-up the OHCA-survivors are informed about this sub-study, and for those who consent to participate a second follow-up will take part within 4 weeks. The included OHCA-survivors will be provided a hip-placed accelerometer to wear for one week. After this week they will answer two self-reported questions about physical activity. Information regarding variables of assumed importance for physical activity will be collected. A control group of myocardial infarction patients will be included in 1:1 ratio and perform the same follow-up except for wearing the Actigraph. The first TTM2-patient was included in November 2017, and the first sub-study patient in July 2018.
The results from this sub-study will provide important information of OHCA-survivors physical activity, and how to measure it among OHCA survivors.
