It is estimated to include 4000 patients with myocardial infarction during 2 years. Patients will wear the accelerometer for 7 days at follow-up visits (2 months and 1 year) after discharge. The investigators will examine the dose-response relations of several exposure variables from the accelerometer measurements with the outcomes.
The association between objectively measured physical activity intensities (light, moderate and vigorous), sedentary time and clinical outcomes has not been clarified in patients after a myocardial infarction.~The overall objective of the study is to explore associations between accelerometer measured physical activity and clinical outcomes after a myocardial infarction. Moreover, the association between changes in physical activity and outcomes will be assessed.
