Cardiac rehabilitation and mortality reduction after myocardial infarction: the emperor's new clothes? Evidence in favour of cardiac rehabilitation.

This piece highlights the strength of evidence in favour of cardiac rehabilitation (CR) and postulates that the emperor is indeed well dressed. The reason why a single negative trial, in the UK, has caused such hullabaloo in the literature and clinical practice is examined against overwhelming evidence from over 40 positive randomised controlled trials. The lack of motivation to promote lifestyle change and the role of patients in determining outcome is also explored. To conclude, we set the scene for the final chapter of this story by outlining what needs to be done to answer the question about the real-world effectiveness of CR.
