Coronary artery calcium (CAC) can help to predict risk for adverse cardiovascular (CV) events. In this analysis of a large South Korean cohort of apparently healthy men and women without incident CV disease, researchers investigated the relation of physical activity to 5-year progression in CAC scores.
In more than 25,000 participants (mean age, 42; 47% reported to be inactive, 15% reported to be highly active) with two CAC measurements, “health-enhancing” (highly active) self-reported activity level was associated with mildly higher adjusted baseline CAC score than was inactivity (mean CAC scores, 12.04 vs. 9.45). Moreover, compared with inactive participants, active participants' adjusted 5-year increases in CAC were larger (mean increases…
