The impact of drop-out in cardiac rehabilitation on outcome among coronary artery disease patients

Background: The effect of adherence to cardiac rehabilitation (CR) on outcome is not clear. Therefore, we aimed to assess the impact of drop-out for non-medical reasons of CR on event-free survival in coronary artery disease (CAD). Methods: A total of 876 patients who attended CR after acute coronary syndrome (ACS), percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) were included. Drop-out was defined as attending 50% of the training sessions. A combined endpoint of all-cause mortality and rehospitalization for a cardiovascular event was used to specify event-free survival. Differences in clinical characteristics were assessed and parameters with p
