Coronary calcifications (CC) are the witness of atheromatous disease because they lies in intima. This is a best stamp of coronary atheromatosis than all the well know risk factors. CC scores is perfectly estimated by EBT. The reproductibility expressed in logarithm data is 7.2% in inter-examination, 1.3% in inter-observers, 2% in intra-observers [4]. CC detection is more specific in young population than in old population because CC appear and increase with age in asymptomatic patients [12]. But the score curve raised higher in symptomatic than in asymptomatic subjects. A patient with an abnormal score for his age will have 5 to 10% of ischemic cardiac disease during the following 6 months [11].
