AI Article Synopsis
- A study involving 66 patients with angina at rest used exercise electrocardiography, thallium scintigraphy, and coronary arteriography to assess coronary artery disease.
- The results showed that while exercise electrocardiography was very predictive (93%) of coronary artery disease, it had low sensitivity (52%).
- Thallium scintigraphy demonstrated similar predictive ability (91%) but was much more sensitive (91%), particularly benefiting patients with inconclusive exercise electrocardiograms lacking Q waves.
Article Abstract
Sixty six patients with angina at rest were investigated by exercise electrocardiography, thallium scintigraphy, and coronary arteriography. A positive exercise electrocardiogram was highly predictive (93%) but poorly sensitive (52%) of coronary artery disease (greater than or equal to 50% stenosis). Thallium scintigraphy was as predictive of the presence of coronary artery disease (91%) but was also highly sensitive (91%). The diagnostic contribution of the thallium scan was greatest in those patients with an inconclusive exercise electrocardiogram without Q waves.
