Abstract

Aims To investigate whether out-of-hospital cardiac arrest (OHCA) survivors had lower levels of self-reported physical activity compared to a non-cardiac arrest control group with myocardial infarction (MI), and to explore if symptoms of anxiety, depression, kinesiophobia (fear of movement) and fatigue were associated with a low level of physical activity. Methods Predefined case–control sub-study within the international Targeted Hypothermia versus Targeted Normothermia after Out-of-Hospital Cardiac Arrest (TTM2) trial. OHCA survivors at 8 of 61 TTM2 sites in Sweden, Denmark and the United Kingdom were invited. Participants were matched 1:1 to MI controls. Both OHCA survivors and MI controls answered two questions on self-reported physical activity, categorized as a low, moderate, or high level of physical activity, and questionnaires on anxiety and depression symptoms, kinesiophobia, and fatigue 7 months after the cardiac event. Results Overall, 106 of 184 (58%) eligible OHCA survivors were included and matched to 91 MI controls. In total, 25% of OHCA survivors and 20% of MI controls reported a low level of physical activity, with no significant difference (p=0.13). Symptoms of kinesiophobia and fatigue were significantly associated with a low level of physical activity in both groups. OHCA survivors had significantly more kinesiophobia compared to MI controls (18% versus 9%, p=0.04), while levels of anxiety and depression symptoms and fatigue were similar. Conclusion OHCA survivors had similar levels of physical activity compared to matched MI controls. High level of kinesiophobia and fatigue were associated with a low level of physical activity in both groups.
