Overview
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.
Description
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.
