You probably know someone who had a heart attack and never quite got around to the rehab program.
The appointments were far away, work got in the way, or life simply moved on. For many, that one gap in care sets up the next scare.
A major update to the Cochrane review on exercise-based cardiac rehabilitation now says home programs can be just as effective as hospital-based ones for people with coronary heart disease.
The authors pooled 85 randomized trials with 23,430 patients.

Within 6 to 12 months of starting a program, one heart attack was prevented for every 71 people who did exercise-based rehab.
One hospital admission was prevented for every 17.
That matters because most heart patients never show up.
According to the CDC, roughly 1 in 3 US heart attack survivors reported getting cardiac rehab in surveillance across 20 states and DC.

The main barriers were cost, distance, limited awareness and low referral rates from doctors.
What the review actually found
The updated review was published on September 18, 2026 in the Cochrane Database of Systematic Reviews.
It was led by researchers at the University of Glasgow and added 22 new trials to the earlier version.
Twenty-seven of the included studies tested home-based programs, some delivered by phone app or online.

The authors reported that these digital and home-based programs produced clinical results on par with traditional center-based rehab.
Participants also reported better physical function, more energy and better mental wellbeing on standard quality-of-life measures.
The authors stressed that properly prescribed exercise is safe for most patients and plays a vital role in recovery.
One caveat is that women made up only 17 percent of trial participants, so the evidence is strongest for men.

What home cardiac rehab actually looks like
A home program is not a workout video.
A joint scientific statement from the American Heart Association and the American College of Cardiology describes it as a full package.
That means medical evaluation, a prescribed exercise plan, risk-factor coaching, patient education and behavioral support.
Most of the contact is by phone, with occasional video visits to walk through specific exercises.

Heart rate is tracked with a wearable or home monitor, and patients keep a journal of vital signs, activity and food.
Common exercise choices are walking, stationary cycling, light circuit training and other moderate aerobic work.
Some programs start with a short run of supervised sessions in a clinic with heart-rhythm monitoring, then move the rest of the work home.
That hybrid model is often used for higher-risk patients.
Who the home version is right for
Home-based programs are usually offered to patients considered low to moderate risk, once the acute phase of their event has been treated and stabilized.
Patients with unstable symptoms, serious irregular heart rhythms or recent complex procedures are generally kept in supervised clinic-based rehab, at least to start.
Patients leaving the hospital after a heart event can ask their cardiologist which cardiac rehab options are available in their area.
That includes hybrid programs that start in a clinic and continue at home.
