Measurement of Coronary Artery Calcium in Elderly Patients.
Quantification of coronary artery calcium by electron beam and spiral computed tomography (CT) is being increasingly utilized as a technique to assess the presence and extent of coronary artery disease (CAD) as well as the prognosis for clinical events in both symptomatic and asymptomatic individuals. Much of the demand for this procedure is generated by patients exposed to marketing efforts, and patients often ask physicians about the value of this test. Since elderly patients have a high prevalence of coronary artery calcium as well as a higher incidence of clinical CAD, the interpretation and clinical utility of this test differs from that for younger individuals. This paper attempts to review currently available information concerning coronary artery calcium quantification and its potential uses in elderly patients.
