OBJECTIVE - We evaluated family history as a predictor of incident and progressive coronary artery calcium (CAC) using data from the Multi-Ethnic Study of Atherosclerosis (MESA).

BACKGROUND - MESA is a multi-center prospective study of 6814 asymptomatic individuals. The relationship between family history of coronary heart disease (CHD) and CAC incidence or progression has not been described previously.

METHODS - A total of 5099 participants had detailed information about family history of CHD (late versus premature and parental versus sibling history). The mean time between CAC scans was 3.1 ± 1.3 years. The association of late versus premature family history was assessed against CAC change using multivariate regression model adjusted for demographics and cardiac risk factors.

RESULTS - A family history of premature CHD was associated with an odds ratio (OR) of 1.55 (p < 0.01) for incident development of CAC after adjusting for risk factors and demographics. A premature family history was associated with 14.4 units (p < 0.01) greater volume scores compared to those with no family history in similarly adjusted models by median regression analysis. A combined parental and sibling family history was associated with the greatest incidence and progression in demographic-adjusted models. Caucasians demonstrated the most consistent predictive relationship between family history of premature CHD and incidence (p < 0.01) and progression (p < 0.05) of CAC, though no significant interaction with ethnicity was noted.

CONCLUSIONS - Family history of premature CHD is associated with enhanced development and progression of subclinical disease, independent of other risk factors, in a multiethnic, population-based study.
