Cardiac rehabilitation can improve health outcomes and quality of life for people with coronary heart disease. Evidence suggests that it can reduce mortality by as much as 20-25 percent over three years. Rehabilitation offers people comprehensive and tailored help with changing their lifestyle, involving education and psychological input, as well as exercise training. Under the NSF, all heart patients, prior to leaving hospital, should be invited to participate in a multidisciplinary programme of secondary prevention and cardiac rehabilitation.
Here you can find chapter 7 of the CHD NSF, which deals with cardiac rehabilitation. It covers the reasons for providing cardiac rehabilitation, aims, priorities and service models.
