Thallium-201 stress imaging in hypertensive patients.
To assess the potential effect of hypertension on the results of thallium-201 stress imaging in patients with chest pain, 272 thallium-201 stress tests performed in 133 hypertensive patients and 139 normotensive patients over a 1-year period were reviewed. Normotensive and hypertensive patients were similar in age, gender distribution, prevalence of cardiac risk factors (tobacco smoking, hyperl...
متن کاملMyocardial imaging with thallium-201 at rest and during exercise. Comparison with coronary arteriography and resting and stress electrocardiography.
Myocardial imaging with intravenous thallium-201 (201Tl) was performed at rest and following maximal treadmill exercise in 101 patients with suspected coronary artery disease. Results were interpreted from Polaroid scintiphotos by three independent observers with complete interobserver agreement in 79%. Of 25 patients with no or insignificant coronary artery disease (less than 50% diameter sten...
متن کاملThallium-201 myocardial scintigraphy in patients with triple-vessel disease and ischemic exercise stress tests.
Thirty patients with triple-vessel coronary artery disease proven by angiography, symptomatic angina and a positive ECG stress test were evaluated with thallium-201 (201TI) scintigraphy. Twenty patients also had aortocoronary saphenous vein bypass surgery; 15 of them had repeat noninvasive evaluation. Seventy percent of these patients showed ischemia by 201TI scintigraphy, of which one-half ret...
متن کاملDifferentiation of false- from true-positive ECG responses to exercise stress by thallium 201 perfusion imaging.
false-positive and true-positive ECG responses to exercise stress. Thirty-five patients referred for coronary angiography because of an exercise test interpreted as positive for ischemic ST segment changes (1.0 mm or more reversible horizontal or downsloping ST depression), but who were asymptomatic or had a history of atypical chest pain, underwent repeated exercise testing in conjunction with...
متن کاملLung thallium-201 uptake during exercise emission computed tomography.
To test whether the analysis of lung uptake is worth adding to the interpretation of exercise thallium-201 (201TI) emission computed tomography (ECT), a lung/heart ratio of 201TI uptake was measured from an anterior image during ECT in 25 clinically normal (Group 1), 91 angiographically normal (Group 2), and 265 subjects with coronary artery disease (Group 3). The mean +2 s.d. of ratios in Grou...
