At the end of this presentation, participants will be able to:
1- Describe when to order a regular stress test vs. a nuclear stress test.
2- Understand when an echocardiogram is more useful to evaluate an ejection fraction than a MUGA.
3- Discuss the risks/benefits of cardiac catheterization and when to refer a patient.

Cardiac Diagnostic Testing 2
Regular Stress Testing
Single-Photon Emission Computed Tomography (SPECT) Myocardial Perfusion Imaging
Stress Echo
To rule out CAD
S/P MI
Evaluate exercise capacity
Standard exercise ECG testing is recommended for patients with an intermediate pretest probability of IHD who have an interpretable ECG and at least moderate physical functioning or no disabling co-morbidity.
Exercise stress with nuclear MPI or echocardiography is recommended for patients with an intermediate to high pretest probability of IHD who have an uninterpretable ECG and at least moderate physical functioning or no disabling co-morbidity

Cardiac Diagnostic Testing 12
Patients with SIHD who have survived sudden cardiac death or potentially life-threatening ventricular arrhythmia should undergo coronary angiography to assess cardiac risk.
Patients with SIHD who develop symptoms and signs of heart failure should be evaluated to determine whether coronary angiography should be performed for risk.
Patients with SIHD whose clinical characteristics and results of noninvasive testing indicate a high likelihood of severe IHD and when the benefits are deemed to exceed risk.
