Twenty-eight patients referred for coronary angiography because of chest pain syndromes underwent exercise electrocardiography and dipyridamole testing with electrocardiography, thallium perfusion imaging, and body surface mapping. The angiographic finding of at least one greater-than-50% luminal obstruction of a major coronary branch defined significant coronary artery disease. In the 28 patients without prior myocardial infarction, dipyridamole testing using thallium scintigraphy had a sensitivity and specificity of 77% and 53%, respectively, whereas this test in conjunction with body surface mapping had a sensitivity and specificity of 92% and 80%, respectively. The increased specificity of surface mapping was statistically significant (P<.0.5). Dipyridamole testing in conjunction with body surface mapping is at least as accurate as dipyridamole-thallium testing.
