After a Heart Event or Cardiac Surgery

Structured cardiac rehabilitation after a heart attack, stenting or bypass surgery reduces the risk of a further heart attack and of hospital admission, and over longer follow-up it is associated with fewer deaths from cardiovascular causes 2. After valve surgery the evidence is much thinner: trials have been too few and too small to show whether rehabilitation changes survival, hospital admission or quality of life 3. Despite the strength of the evidence after a heart attack or revascularisation, cardiac rehabilitation remains one of the most consistently under-used treatments in cardiology.

The programme rebuilds exercise capacity under medical supervision, so that the heart is challenged progressively rather than avoided.

After a myocardial infarction, after coronary bypass, after valve surgery or stenting, in stable heart failure, and where hypertension has produced a decline in functional capacity.

In stable heart failure in particular, supervised exercise improves quality of life and reduces hospital admissions, although it has not been shown to change survival 4. Patients are frequently told to avoid exertion, and that advice does more harm than the exertion would.

Assessment first: exercise capacity, cardiac status from the treating cardiologist, medication, and risk stratification. Then exercise prescribed to a target heart rate range with monitoring during sessions, progressed on measured response rather than on how the patient feels on the day.

Alongside it: breathing and endurance training, and structured secondary prevention — activity, weight, smoking and medication adherence. The prevention component is not an add-on: it targets the risk factors behind further events, and it has to continue long after the supervised sessions end.

We need your cardiology records — ejection fraction, procedure details, current medication, and any exercise test results — before starting. We work to the parameters your cardiologist sets and report back to them.

If those records are not available we will say what we can and cannot safely deliver without them rather than proceeding on assumption.

Heart rate, rhythm, blood pressure response and symptoms during exercise, with the intensity set from an exercise test rather than estimated from age.

Supervision level is matched to risk: some people need continuous monitoring initially, most progress to independent exercise, and knowing which is which is the point of the assessment.

Yes, and the evidence supports it. In a Cochrane review of 24 trials, home-based programmes supported by healthcare staff and centre-based programmes gave similar results for exercise capacity and survival up to 12 months, and mostly similar quality of life, although the certainty of that evidence is low 6.

Trials in heart failure point the same way: the effects of rehabilitation were similar whether it was delivered at home or in a centre 4. What makes the home phase work is structure — a written exercise prescription with a target intensity, a way of checking that intensity, planned progression and regular contact with a cardiac rehabilitation service. The supervised phase is where safe limits are found; the home phase is where they are used and gradually extended.
