Heart patients may benefit more from exercise than healthy people

Exercise can do more to lower the risk of premature death for patients with cardiovascular disease than for healthy people, a new study suggests.

Healthy people did have a lower chance of dying during the study when they were more physically active. But the beneficial effect of exercise was more pronounced for people with heart problems, researchers reported in the European Heart Journal and at the annual meeting of the European Society of Cardiology in Paris.

The study team scored participants' exercise levels and intensity based on a measure known as metabolic equivalent of task (MET) minutes per week. For optimal health, adults should get at least 500 MET minutes per week. (Because MET minutes can be difficult to calculate, an easier recommendation to follow is to get at least 150 minutes a week of moderate to vigorous exercise.)

When people had heart disease, every additional 500 MET minutes per week of exercise was associated with a 14 per cent lower risk of dying from all causes during the study. For healthy people, the same increase in activity was tied to only a 7 per cent lower mortality risk.
