Authors' conclusion

This study found that PA volume was not associated with progression of CAC in a large cohort of healthy men and women who were initially free of overt cardiovascular disease.

Study context

Population
Apparently healthy men and women aged ≥40 years with multiple preventive medicine visits at the Cooper Clinic (Dallas, Texas), 1998–2019
Participants
8,771 men
Exposure
Higher vs lower physical activity volume
Outcome
Rate of mean CAC progression between visits, by PA volume (per 500 MET-min/wk); CAC progression to ≥100 AU by baseline PA
Follow-up
Mean (SD) 7.8 (4.7) years

Main finding

As reported in the abstract

CAC progression per year
Per 500 MET-min/wkDifference in rate of CAC progression per year (95% CI)
men
0.0%(−0.1% to 0.1%)
women
0.0%(−0.4% to 0.5%)

Per 500 MET-min/wk, as printed

Rate of mean coronary artery calcium (CAC) progression per year, men, independent of mean physical activity (PA)
28.5%
Rate of mean CAC progression per year, women, independent of mean PA
32.1%
