  • Thallium Stress Test: Purpose, Procedure, and Risks

    A thallium stress test is a nuclear imaging test that shows how well blood flows into your heart while you’re exercising or at rest. This test is also called a cardiac or nuclear stress test.

  • Symptoms of Patients With Silent Ischemia as

    This study was undertaken to determine whether patients with silent ischemia (SI) (a positive thallium stress test without chest pain) have nonchest-pain symptoms that might serve as “anginal equivalents.” Two hundred ninety-four individuals on completing a stress test were requested to score ten symptoms on a questionnaire (0 absent; 3 severe).

    Cardiac events occurred in 20 patients (12.6%) with stress/delay redistribution, 13 patients (12%) with ischemia detected by thallium reinjection only and 15 patients (15%) with infarction only. The size of the reversible thallium defect by either stress/delay redistribution imaging or reinjection scintigraphy did not predict cardiac events.

    Objectives. The purpose of this study was to compare thallium reinjection with standard stress/delay redistribution for the prediction of cardiac events. Background. Although thallium reinjection enhances the detection of viable myocardium, its contribution to prognosis over stress/delay redistribution in a general referral population has not been clearly evaluated.

    Thallium toxicity is frequently overlooked by traditional medical practitioners and even most detox ‘experts.’ Thallium bioacculumates, meaning, it builds up in the body over time.
