ABSTRACT
INTRODUCTION:
There is discussion about incorporating a family history (FamHis) of premature coronary artery disease (CAD) in risk score algorithms. However, FamHis provides information on individual risk. Coronary artery calcification score (CACS) is a metric of atherosclerosis that may determine the individual risk within families at high risk of premature CAD.METHODS:
In asymptomatic individuals (n = 704), we assessed the association between FamHis of CAD and elevated CACS. To assess the predictive value of CACS in individuals with a FamHis of CAD, we performed a post-hoc analysis on the St. Francis Heart Study (n = 834). We assessed, in a case control design, the risk of future CAD in individuals with a FamHis of CAD and either CACS >80th percentile or no CACS at all.RESULTS:
Individuals with a FamHis for CAD had an increased risk for elevated CACS (adjusted odds ratio (OR) 2.23 (95% CI 1.48-3.36); p < 0.05), compared to those without a FamHis. In the prospective study (3.5 years follow-up), the event rate equally low in those with a positive FamHis and a negative FamHis (0% vs. 1%), if they had a CAC of 0. However, in those with CACS >80(th) percentile, a FamHis of CAD doubled the CAD event rate (positive FamHis 12.5% vs. negative FamHis 6.8%; adjusted HR 2.08 (95% CI 1.09-3.87; p < 0.05).CONCLUSION:
CAC scoring leads to risk discrimination among those with a positive FamHis for premature CAD. These results support testing CAC score in asymptomatic individuals with a positive FamHis to identify a high risk population.Palabras clave
