In the workup of a 45-year-old man with suspected coronary artery disease, the following is/are true:


  1. Thyroid tests are included to rule out hyperthyroidism
  2. Typically positive stress ECG would show elevated ST segments
  3. Dipyridamole is a useful adjunct to thallium scanning as it increases coronary perfusion pressure
  4. Persisting defects on thallium scan indicate reversible myocardial ischemia

a. Thyroid tests are included to rule out hyperthyroidism

Diagnostic studies for coronary artery disease should detect risk factors such as diabetes mellitus, hyperlipidemia and hyperthyroidism. The stress ECG typically shows downward sloping ST segment depression. Dipyridamole is a coronary artery vasodilator that reduces systemic and coronary perfusion pressures. The persisting thallium scan defect reflects irreversibly scarred myocardium.
