Exercise reduces heart failure risk

INCREASED physical activity has been linked, for the first time, to the prevention of heart failure.

A US meta-analysis of 10 cohort studies covering nearly 300,000 participants found regular physical activity is associated with a significantly lower risk of heart failure compared with a sedentary lifestyle, particularly in the elderly.

The type of physical activity was not important, but more vigorous exercise had a stronger effect.

Physical activity was found to boost cardiac function, blood flow, metabolism and the nervous system.
