However, under normal conditions, this pressure gradient does not impair endocardial blood flow, because a greater blood flow to the endocardium during diastole compensates for the greater blood flow to the epicardium during systole, and the tone of the endocardial resistance vessels is less than the tone of the epicardial vessels. During the perfusion test, depending on the health of the patient, there may be several risks that are attached to a cardiac perfusion test.
