Association of Coronary Artery Calcium and Coronary Heart Disease Events in Young and Elderly Participants in the Multi-Ethnic Study of Atherosclerosis

Increased CAC imparts an increased CHD risk in younger and elderly individuals. CAC is highly predictive of CHD event risk across all age groups, suggesting that once CAC is known chronologic age has less importance. The utility of CAC scoring as a risk-stratification tool extends to both younger and elderly patients.
