Insights
Many eligible patients, especially women and older individuals, do not use cardiac rehabilitation. Factors like revascularization procedures significantly predict its use, highlighting disparities in access to cardiac recovery programs.
Area of Science:
- Cardiology
- Public Health
- Rehabilitation Medicine
Background:
- Cardiac rehabilitation is crucial for patient recovery after cardiac events.
- A significant number of eligible patients do not participate in cardiac rehabilitation programs.
Purpose of the Study:
- To document patterns of outpatient cardiac rehabilitation use.
- To identify factors predicting patient participation in cardiac rehabilitation.
Main Methods:
- The study enrolled 3,841 patients suspected of acute myocardial infarction (MI).
- Participants were contacted one year post-hospitalization to assess cardiac rehabilitation use.
Main Results:
- 47% of MI patients and 21% of angina patients used outpatient cardiac rehabilitation.
- Cardiac rehabilitation use increased with revascularization procedures (e.g., coronary artery bypass grafting, angioplasty).
- Women, older patients, those with less education, and the unemployed were less likely to participate.
Conclusions:
- Significant disparities exist in cardiac rehabilitation utilization.
- Lower utilization rates were observed among women, older individuals, less educated, and unemployed patients.
- Age and revascularization procedures were the strongest predictors of cardiac rehabilitation use.
Background:
A significant proportion of eligible patients do not participate in cardiac rehabilitation. The purpose of this study was to document patterns of outpatient cardiac rehabilitation use and identify factors predicting its use.
Methods:
The Acute Myocardial Infarction Registry of the Minnesota Heart Survey enrolled 3,841 patients admitted on suspicion of acute myocardial infarction (MI) to the coronary care units at six Minneapolis-St. Paul metropolitan hospitals. Participants were contacted 1 year after index hospitalization and asked if they participated in cardiac rehabilitation since discharge.
Results:
Among those discharged with a MI, 47% participated in outpatient cardiac rehabilitation or an exercise program at an exercise facility, home, or both during the 1-year follow-up period. Among those discharged with angina, 21% attended cardiac rehabilitation. Usage increased when cardiac revascularization procedures were performed during the index hospitalization. Women with an angina or MI diagnosis were significantly less likely to use cardiac rehabilitation than men. Older patients were also less likely to use rehabilitation, with gender difference persisting across age strata. As education increased, cardiac rehabilitation utilization increased. Those not employed were less likely to use cardiac rehabilitation services. The strongest independent predictors of cardiac rehabilitation utilization were age and revascularization procedures (coronary artery bypass grafting or coronary angioplasty), simultaneously adjusting for demographic information, and cardiovascular disease risk factors.
Conclusions:
These data suggest that there is a disparity in cardiac rehabilitation utilization with lower rates among women, older individuals, those with less education, and the unemployed.
