  "summary_plain": "A medically supervised program for people with heart disease or after a heart event or heart procedure. MedlinePlus says a team of specialists builds a plan that includes exercise training, education on heart healthy living and counseling to reduce stress, with the aims of returning to an active life and lowering the chance of further heart problems. It is offered after a heart attack, angioplasty or bypass surgery for coronary heart disease, valve repair or replacement, heart or lung transplant, angina and heart failure. An updated Cochrane review of 85 trials in people with coronary heart disease found fewer heart attacks and fewer hospital admissions at 6 to 12 months compared with no exercise, likely little or no difference for some other outcomes, and uncertain effects for others. Many eligible people never take part (see the participation page).",
  "summary_technical": "Subtype rehabilitation. MeSH Cardiac Rehabilitation (D000072038) is an exact match. The evidence recorded here is the Cochrane review of exercise-based cardiac rehabilitation for coronary heart disease (85 trials, 23,430 participants; the review compared exercise training alone, or combined with psychosocial or educational interventions, with no exercise), split into four claims by GRADE certainty and follow-up, and the MedlinePlus description of who is offered it and what it includes. A joint scientific statement from rehabilitation and cardiology societies describes it as using patient education, health behavior modification and exercise training to improve secondary prevention outcomes, and as significantly underused in the United States. The Cochrane review covers coronary heart disease only. A heart failure trial of a supervised exercise training program is recorded separately; its registry record and abstract do not call that program cardiac rehabilitation, so this record does not link the trial to it.",

At medium-term follow-up (more than 12 to 36 months) there may be little to no difference in all-cause mortality (risk ratio 0.90, 95% CI 0.80 to 1.02; 15 trials), myocardial infarction (1.07, 0.91 to 1.27; 12 trials), percutaneous coronary intervention (0.96, 0.69 to 1.35; 6 trials), coronary artery bypass graft (0.97, 0.77 to 1.23; 9 trials) and all-cause hospitalisation (0.92, 0.82 to 1.03; 9 trials), but a large reduction in cardiovascular mortality was found (0.77, 0.63 to 0.93; 5 trials); the evidence is uncertain for cardiovascular hospitalisation (0.92, 0.76 to 1.12; 3 trials). At long-term follow-up (more than 3 years) there may be little to no difference in all-cause mortality (0.91, 0.75 to 1.10), while exercise-based cardiac rehabilitation may result in a large reduction in cardiovascular mortality (0.58, 0.43 to 0.78; 8 trials) and myocardial infarction (0.67, 0.50 to 0.90; 10 trials); the evidence is uncertain for coronary artery bypass graft (0.66, 0.34 to 1.27; 4 trials) and percutaneous coronary intervention (0.76, 0.48 to 1.20; 3 trials).
