The Physical Activity Post Myocardial Infarction SWEDEHEART Prospective Cohort Study (ACTIVITY-SWEDEHEART)

• Status: Recruiting
• Phase: —
• Study type: Observational

Summary

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.

Detailed 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.

Conditions

• Myocardial Infarction

Interventions

Type	Name	Description
OTHER	Accelerometer measurement	Study personnel will initiate an accelerometer and inform the patient to wear the accelerometer with an elastic belt on their right hip during waking hours for seven consecutive days. Moreover, patients are instructed to register their wear time in an activity diary in paper form. In addition, patients will register their working hours, if relevant. After seven days, patients send back the accelerometer and diary in a pre-paid envelope. The same procedure is repeated at the second follow-up visit at 1 year.
