"Why would you not listen? It is like being given the winning lottery numbers and deciding not to take them": semi-structured interviews with post-acute myocardial infarction patients and their significant others exploring factors that influence participation in cardiac rehabilitation and long-term exercise training

Purpose Despite the clinical benefits, coronary artery disease patient participation rates in cardiac rehabilitation (CR) and long-term exercise are poor. This study explored the factors related to participation in these interventions from the perspectives of post-acute myocardial infarction (AMI) patients and their significant others. Methods Semi-structured interviews were performed with post-AMI patients (number (n) = 10) and their significant others (n = 10) following phase-III and phase-IV CR. Reflexive thematic analysis with an inductive orientation was utilised to identify themes within the dataset (ClinicalTrials.gov identifier: NCT03907293). Results The overarching theme of the data was a perceived need to improve health, with the participants viewing health benefits as the principal motive for participating in CR and long-term exercise training. Three further themes were identified: motivation, extrinsic influences, and CR experience. These themes captured the underlying elements of the participants' decision to take part in CR and long-term exercise training for the purpose of health improvements. Conclusion An AMI collectively impacts the attitudes and beliefs of patients and their significant others in relation to CR participation, long-term exercise, and health. The factors identified in this study may inform strategies to promote patient enrollment in CR and adherence to long-term exercise.
