Why the study?
Does attending all 36 sessions of cardiac rehabilitation reduce the risks of death and myocardial infarction at 4 years in elderly Medicare beneficiaries compared to attending fewer sessions?

Completing the full 36-session course of cardiac rehabilitation is associated with improved long-term survival and reduced risk of myocardial infarction in elderly patients compared to partial completion.
Answers are grounded in this paper and cite their sources.
May support encouraging full cardiac rehabilitation completion in elderly patients; extends observational dose-response data but leaves causality open.
Among Medicare beneficiaries, a strong dose-response relationship existed between the number of cardiac rehabilitation sessions and long-term outcomes. Attending all 36 sessions reimbursed by Medicare was associated with lower risks of death and MI at 4 years compared with attending fewer sessions.
