Cardiac rehabilitation: structure, effectiveness and the future.

Despite advances in the investigation and treatment of angina and myocardial infarction, and increased knowledge of the factors associated with the development and progression of ischaemic heart disease, it remains the leading cause of death and morbidity in the majority of industrialized countries. Cardiac rehabilitation provides a means of modifying lifestyle and other risk factors in patients presenting with established, symptomatic coronary artery disease, thereby reducing the risk of further cardiac events. It has also been proven to be cost-efficient.
