Abstract
This review overviews three topic areas observed to be highly active in the cardiac rehabilitation (CR) research literature published in 2019 and 2020. Topics summarized were enrollment or adherence in CR programs; mental health, particularly depression, stress, and anxiety of patients participating in CR programs; and patients participating in CR programs with diagnoses other than coronary artery bypass graft, myocardial infarction, or percutaneous coronary interventions.
