Cardiovascular rehabilitation (CR) supports postacute cardiovascular patients through a multidisciplinary intervention to regain the best possible physical and mental health as well as professional and social integration and to maintain it in the long term. Secondary prevention medication, exercise therapy and training, healthy lifestyle counselling, as well as participation-oriented (psycho)social and occupational therapy measures complement each other in multimodal cardiovascular rehabilitation. After acute coronary syndrome (ACS) and coronary artery bypass grafting (CABG), CR significantly reduces mortality and hospitalization rates. In the case of chronic coronary syndrome or stable chronic heart failure (HFrEF, HFpEF), an improvement in physical exercise capacity and quality of life has been demonstrated.
