The .gov means its official. Its typically indicative of one of two things. There is poor blood flow to that area of the heart. This is typically seen as a reversible perfusion defect, in that blood flow is insufficient to meet exercise demand and the defect appears with exercise or some other stress. Ischemia can also be acute, due to a sudden reduction in blood flow, or chronic, due to slowly decreasing blood flow. Learn what happens before, during and after a heart attack occurs.

This statement presents two questions: Why ARE anteroseptal (aka anteroapical) MIs more common than anterolateral MIs and Why are we now calling this infarction an antero apical infarction? In regional perfusion, a specific area of the body (usually an arm or a leg) receives high doses of anticancer drugs through a blood vessel. Anteroapical refers to the front tip of the heart. Furthermore, the frequency of abnormalities found on MPI increases over time with right ventricular outflow tract pacing. Perfusion defects of the heart are a technical term referring to findings on a cardiac Magnetic Resonance Imaging scan (MRI). A reversible defect refers to an area of the heart that still has good blood flow at rest.

Publication types Research Support, Non-U.S. Gov't Partially reversible defects represent the presence of both scar tissue and viable, ischemic tissue in an area of the heart. An abnormal result in both phases of your stress test is an indication that your hearts blood flow is poor, regardless of your exertion level. The development of single photon emission computed tomography (SPECT) led to improved assessments of myocardial perfusion, and the use of electrocardiographic gating made accurate measurements of ventricular wall motion, The degree of reversibility of a perfusion defect is identified on post-stress images as an area of decreased radiopharmaceutical activity that improves or disappears on rest or redistribution images.
