CAD: Coronary artery disease; CCTA: Coronary Computed Tomography Angiography; CMR: Cardiac Magnestic Resonance; ECG: Electrocardiogram; echo: echocardiography; SPECT: Single-Photon Emission Computerized Tomography; PET: Positron Emission tomography. The Table 2 summarize the multiple non-invasive stress tests available at this day for coronary artery disease screening. Each exam is characterized by its specificity and sensibility. The exam choice depends on the patient’s clinical situation.
