Heart disease patients live longer when they exercise

Older adults with heart disease who regularly exercise, even a little bit, may live longer than they would without any physical activity, a Norwegian study suggests.
Researchers examined three decades of data on 3,307 adults who had been diagnosed with coronary heart disease after a heart attack or an episode of severe chest pain, known as angina, caused by inadequate blood supply to the heart. By the time half of the patients had been in the study for at least 15 years, 1,493 of them had died.
Compared to people who were inactive, participants who consistently got the minimum recommended amount of exercise for adults were 36 per cent less likely to die during the study. If these very active people scaled back their workouts over time, they were still 26 per cent less likely to die than sedentary individuals.
