Cardiac Rehabilitation After a Heart Attack: Formal Referral or Home-Based Care
A single patient for whom the standard next step after a heart attack assumes a level of mobility she doesn't have. The disagreement is about whether that standard step still deserves to be pursued, or whether the same effort belongs somewhere else entirely.
R.M., an 82-year-old woman, still hosts her book club once a month in her apartment, though these days it takes her a full minute with her walker just to get from the living room to the kitchen for refreshments. Severe osteoarthritis in both knees has limited her mobility for years, well before anything was wrong with her heart, and she lives independently with help from a home health aide three mornings a week. She was admitted four days ago with an NSTEMI, treated medically without revascularization given diffuse, non-focal coronary disease not amenable to a single culprit-lesion intervention, and is now being discharged.
Cardiac rehabilitation reduces cardiovascular mortality and hospital readmission after a myocardial infarction — the all-cause mortality signal is less consistent in contemporary trials — and referral is a standard part of discharge planning regardless of age. The actual question in front of the team is whether that standard step serves her specifically, given that formal center-based programs assume a level of walking capacity and travel independence she doesn't have, and given that participation and completion rates in patients with significant mobility limitations are known to run low even when referral happens. Home-based cardiac rehabilitation programs exist and have shown real benefit in appropriately selected patients, which reframes the choice from "rehab or nothing" into a genuine decision about which format, if any, actually fits a woman whose walker trip to her own kitchen is already a meaningful exertion. Her kidney function and blood pressure are otherwise stable, which at least removes two of the more common reasons a rehab program might need to be deferred rather than simply reformatted around her.
Which format, if any, actually fits her
I'd still refer her, just not to a standard center-based program. Home-based cardiac rehab exists specifically for patients like her — structured, monitored exercise built around whatever mobility she actually has, rather than assuming she can travel to a facility three times a week. The mortality benefit associated with rehab participation doesn't require a treadmill in a clinic; it requires structured, supervised activity, and that can be built around a walker.
I'd want us to be honest about how much benefit is realistic here before committing her time and the health system's resources to a formal program. She's 82, already fall-risk-limited by her knees, and the exercise capacity a rehab program is built to improve may have less room to grow than it would in a younger, more mobile patient. I'd rather focus our effort on home safety, fall prevention, and making sure her medication regimen is doing as much of the protective work as it can.
I'm not arguing rehab has zero value for her — I'm arguing that when a patient's realistic participation ceiling is genuinely uncertain, the default shouldn't be a referral made out of habit rather than a considered judgment about her.
Whichever way the rehab referral goes, her medication regimen is the part of this that doesn't depend on her mobility at all, and it needs the same attention either way. Beta-blocker, ACE inhibitor, high-intensity statin, and dual antiplatelet therapy all belong on her discharge list. A medically managed NSTEMI still earns a P2Y12 inhibitor alongside aspirin, not aspirin alone, and clopidogrel is the right one for her — ticagrelor and prasugrel both carry more bleeding at her age without a stent to protect. Titration of the rest needs to respect her fall risk specifically, since orthostatic hypotension from an overly aggressive beta-blocker or ACE inhibitor dose could turn a medication meant to protect her heart into the reason she falls and breaks a hip. Start low, recheck standing blood pressures at her first follow-up, and titrate from there rather than reaching for target doses on the discharge paperwork alone.
Home-based cardiac rehabilitation referral placed, built around her actual mobility rather than a standard center-based program; medications started at low doses with orthostatic blood pressure checks arranged at her first follow-up before any titration. Dual antiplatelet therapy with aspirin and clopidogrel started for her medically managed NSTEMI, with a twelve-month course planned and her bleeding risk revisited at each visit.
Not agreed: how much realistic benefit to expect from the rehab referral itself. The rehab physician and geriatrician left holding different expectations, with neither claiming the other was wrong — only that her actual participation over the coming weeks would be the real test of which read was closer.
