High calcium score need not deter men from exercising

Quite high levels of exercise 'appear to be safe'

High-intensity, high-volume physical activity is not associated with increased all-cause or cardiovascular mortality in men, despite an association with higher levels of coronary artery calcification (CAC), researchers say.

Dr Benjamin Levine of the University of Texas Southwestern Medical Center and colleagues studied nearly 22,000 men without cardiovascular disease from 1998 through 2013.

The baseline mean age was 52. Most were runners, but some were cyclists, swimmers or rowers, and a subgroup trained in all three sports.
