Early rehabilitation after acute myocardial infarction: A nationwide inpatient database study

Area of Science:

• Cardiology
• Intensive Care Medicine
• Rehabilitation Medicine

Background:

• The impact and safety of early rehabilitation in intensive care units (ICUs) for patients following acute myocardial infarction (AMI) require further investigation.
• Current evidence on the benefits of early intervention post-AMI is limited, necessitating robust clinical studies.

Purpose of the Study:

• To evaluate the effects of early rehabilitation on activities of daily living (ADL) in patients after AMI.
• To assess the safety and impact of early rehabilitation on hospital resource utilization in post-AMI patients admitted to the ICU.

Main Methods:

• Retrospective analysis of Japanese Diagnosis Procedure Combination inpatient data (July 2010-March 2018).
• Inclusion of 31,603 adult patients with AMI undergoing percutaneous coronary intervention and requiring ICU stay >3 days.
• Comparison between an early rehabilitation group (initiated within 3 days of ICU admission) and a usual care group using inverse probability of treatment weighting.

Main Results:

• No significant difference in Barthel Index scores (ADL at discharge) between early rehabilitation and usual care groups.
• The early rehabilitation group demonstrated significantly shorter hospital and ICU stays.
• Total hospitalization costs were significantly lower in the early rehabilitation group.

Conclusions:

• Early rehabilitation initiation within three days of ICU admission for AMI patients was not correlated with improved ADL at discharge.
• Early rehabilitation appears to be a safe strategy for post-AMI patients.
• This approach is associated with reduced hospital stays and lower overall healthcare costs.
