Exercise stress testing
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 |
Pharmacological stress testing
Test | Indications | Advantages | Disadvantages |
---|---|---|---|
Dobutamine echocardiography | a) Done in patients who can't exercise b) Information on an area of myocardium at risk is needed |
Image qualities comparable to echocardiography | a) Hypertension b) Arrhythmia c) Beta blocker should be held prior to test |
Dobutamine nuclear perfusion |
a) Done in patients who can't exercise 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 |
a)Hypertension b) Arrhythmia c) Beta blocker should be held prior to test Radiation exposure |
Vasodilator nuclear perfusion |
a) Done in patients who can't exercise & have contraindications to dobutamine |
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 |
