TL;DRAbstract

Background: The presence of coronary artery calcium (CAC) is an independent marker of cardiovascular disease (CVD) events and mortality. However, the predictive value of thoracic aorta calcification (TAC), which can be additionally examined without further scanning during assessment of CAC, in predicting coronary heart disease (CHD) events in asymptomatic women and men, is not well-established. Methods: We collected data on risk factors and performed scanning for both TAC and CAC in a multi-ethnic population-based cohort of 6809 individuals (62±10 years, 47% males). Using the same images for each participant, TAC and CAC were computed using the Agatston method. The study subjects had no clinical cardiovascular disease at entry and were followed for a median of 4.1 years. Results: The mean age of the study population was 62±10 years (47% males). At baseline 1904 (28%) participants had detectable TAC, whereas 3392 (50%) had CAC>0. During the follow-up interval, 189 (2.78%) and 108 (1.
