N2 - PURPOSE: To test the hypothesis that angiographically normal coronary arteries in elderly women are identifiable by the absence of coronary calcification on double-helical computed tomographic (CT) scans. MATERIALS AND METHODS: Forty-eight consecutive women (age range, 60-76 years) underwent coronary angiography for chest pain evaluation, as well as double-helical CT. Thirty women (mean age, 65 years ± 5) had coronary artery disease (CAD), defined as any angiographic disease, and 18 women (mean age, 66 years ± 4) had angiographically normal coronary arteries. RESULTS: Women with angiographically normal coronary arteries had lower coronary calcification scores than those of patients with CAD: 5.7 ± 11 versus 580 ± 634, respectively (P = .0004). Seven women with angiographically normal coronary arteries demonstrated mild coronary calcification (score <50). Of the 11 women without coronary calcification, none had CAD. Thus, the absence of coronary calcification on double-helical CT scans in elderly women was predictive of angiographically normal coronary arteries with 61% sensitivity, 100% specificity, and 85% accuracy. CONCLUSION: Double-helical CT is an accurate, noninvasive modality for diagnosing angiographically normal coronary arteries in elderly symptomatic women.
