Management
| Test | Indications | Advantages | Disadvantages |
|---|---|---|---|
| Exercise EKG | Initial test for suspected CAD | Information regarding functional capacity, and hemodynamic changes to exercise |
Contraindicated with baseline EKG abnormalities i.e. LVH , LBBB, > 1mm ST depression, WPW, paced rhythm |
| Stress ECHO | a) With baseline EKG abnormality b) Information on an area of myocardium at risk is needed |
a) Information regarding exercise data, wall motion abnormality, valvular defects, and pulmonary pressures b) portable, cheap, fast |
Image quality, and interpretation difficult with baseline wall motion abnormality, decreased accuracy in single vessel disease, or delayed images |
| Nuclear SPECT perfusion | a) With baseline EKG abnormality b) Information on an area of myocardium at risk is needed |
a) Technetium has superior images compared to thallium but has longer half life. For superior images Technetium is used | Artifacts caused by diaphragm, or breast tissue Radiation exposure |
