Heart attack warning: Exercise can lead to calcification of the arteries – BMJ study

The observational study does have some limitations, including the lack of an objective measure of physical activity.

Furthermore, there was no data on heart attack incidents, calcification density or volume.

The researchers stated that physical activity “may increase coronary atherosclerosis (artery narrowing) through mechanical stress and vessel wall injury”.

“The second possibility is that physical activity may increase CAC scores without increasing [cardiovascular disease] risk,” it was noted.
