Adenosine thallium-201 is superior to exercise thallium-201 for detecting coronary artery disease in patients with left bundle branch block.
OBJECTIVES We sought to assess the comparative diagnostic accuracy of adenosine versus exercise in conjunction with thallium-201 scintigraphy for the detection and localization of coronary artery disease in patients with left bundle branch block on the rest electrocardiogram (ECG). BACKGROUND Patients with left bundle branch block on the rest ECG frequently have artifactual reversible septal ...
متن کاملTHALLIUM-201 STRESS TEST IN 156 PATIENTS WITH SUSPECTED CORONARY ARTERY DISEASE
Currently, myocardial TI-201 scintigraphy is most often performed in conjunction with exercise stress testing in patients with suspected or known CAD. Stress thallium tests were performed for 156 patients with and without old myocardial infarctions complaining of chest pain. All of them underwent contrast coronary angiography. Perfusion defects were mostly manifested as reversible defects ...
متن کاملThallium-201 myocardial SPECT in a patient with mirror-image dextrocardia and left bundle branch block.
A 53-year-old male patient with a previous diagnosis of situs inversus with mirror-image dextrocardia underwent thallium-201 (Tl-201) stress-redistribution myocardial perfusion single photon emission computed tomography (SPECT). Electrocardiogram (ECG) obtained on right hemithorax revealed constant complete left bundle branch block. Tl-201 stress-redistribution SPECT images revealed abnormal pe...
متن کاملDiagnosis of coronary artery disease by controlled coronary vasodilation with adenosine and thallium-201 scintigraphy in patients unable to exercise.
Pharmacological coronary vasodilation induced by dipyridamole is often used in association with thallium-201 myocardial scintigraphy to evaluate the presence and prognostic significance of coronary artery disease. Because dipyridamole acts by blocking the cellular uptake of adenosine, we investigated the usefulness of direct intravenous administration of adenosine, a physiological substance wit...
متن کاملMechanism for abnormal thallium-201 myocardial scintigraphy in patients with left bundle branch block in the absence of angiographic coronary artery disease.
Patients with left bundle branch block (LBBB) often show abnormal images on exercise thallium (T1)-201 scintigraphy without evidence of significant coronary stenosis. We investigated the mechanism for this phenomenon. Six patients with LBBB and without significant coronary stenosis underwent T1-201 SPECT, ECG-gated SPECT imaging with Tc-99m-methoxyisobutyl-isonitrile (MIBI), and atrial pacing s...
