People who are depressed following an incident of heart failure can reduce their risk of death by 40% by engaging in regular exercise, according to a study.
Scientists examined a 189 patients between January 2000 and December 2008 who were enrolled in an exercise rehabilitation programme following an episode of heart failure.
Symptoms of depression in the study group decreased from 22% to 13% following the exercise training.
The patients who continued to suffer from depression after the programme came to a close were found to be four times less likely to survive than those who completed the training.
However, these patients had around twice the chance of survival than the 38 patients who dropped out of the programme without performing any exercise.
