*Groups in <i>blue boxes</i> have a PTP of 15–65%. They could have an exercise ECG if feasible as the initial test. However, if local expertise and availability permit a non-invasive imaging based test for ischaemia this would be preferable given the superior diagnostic capabilities of such tests. In young patients radiation issues should be considered. | *Groups in <i>blue boxes</i> have a PTP of 15–65%. They could have an exercise ECG if feasible as the initial test.

If the ECG made during exercise testing does not show any abnormalities myocardial ischemia becomes unlikely as cause of the complaints. If the diagnosis is still in doubt, the following additional tests may be performed. | If the ECG made during exercise testing does not show any abnormalities myocardial ischemia becomes unlikely as cause of the complaints.

#Magnetic Resonance Imaging can be done with vasodilatory adenosine or stimulating dobutamine to detect wall motion abnormalities induced by ischemia during pharmacological stress. <Cite>REFNAME14</Cite> | #Magnetic Resonance Imaging can be done with vasodilatory adenosine or stimulating dobutamine to detect wall motion abnormalities induced by ischemia during pharmacological stress. <Cite>REFNAME14</Cite> | ||
The findings on stress testing can be used to determine the choice between medical therapy only or medical therapy and invasive assessment of the coronary anatomy in patients with stable angina. Coronary angiography is recommended based upon the severity of symptoms, likelihood of ischemic disease, and risk of the patient for subsequent complications including mortality based on risk scores. <Cite>REFNAME15</Cite> For the algorithm for the initial evaluation of patients with clinical symptoms of angina see Figure 1 | The findings on stress testing can be used to determine the choice between medical therapy only or medical therapy and invasive assessment of the coronary anatomy in patients with stable angina.
