We sought to assess the impact of coronary angiography results on use of lipid-lowering agents among women enrolled in the Women's Ischemia Syndrome Evaluation [WISE] study. WISE is a multicenter study designed to evaluate new diagnostic modalities among women undergoing angiography for suspected coronary artery disease (CAD). History of atherosclerosis, risk factors for CAD, and low-density lipoprotein (LDL) cholesterol are determined at baseline. The percentage of women at LDL cholesterol goal, use of lipid-lowering agents, and eligibility for lipid-lowering therapy were determined based on National Cholesterol Education Program II guidelines at baseline and 6-week follow-up. Among the 212 women for whom angiographic data were available, 84 had known atherosclerosis, 80 had no history of atherosclerosis but > or =2 risk factors (high risk), and 48 had no history of atherosclerosis and <2 risk factors (low risk). At baseline, LDL cholesterol goals were met in 24% women with atherosclerosis, in 56% high-risk women, and in 88% low-risk women. Angiography revealed previously undiagnosed CAD in 70% of the high-risk and in 42% of the low-risk women. After angiography results were available, 6 women started lipid-lowering therapy and 2 stopped. Based on National Cholesterol Education Program II guidelines, 63 additional women would have been eligible for pharmacologic lipid-lowering therapy. Intensification of lipid-lowering therapy was not apparent 6 weeks after coronary angiography in women with newly diagnosed CAD or among women whose diagnosis was confirmed.
