Figure 1 Flow diagram of the postmenopausal women studied. Abnormal scans predominantly reflect ischemia (see text). ECG = electrocardiogram; EPRT = estrogen plus progesterone replacement therapy; ERT = estrogen replacement therapy; HRT = hormone replacement therapy.

Figure 3 Specificity of the stress ECG compared to gated myocardial perfusion imaging in the postmenopausal women studied for detecting coronary artery disease in those with single-vessel as compared to multivessel disease. Solid bar = No HRT; lined bar = ERT; open bar = EPRT. For abbreviations, see Figure 1.
