A perfusion defect is an SMALL area of the heart with diminished blood flow under stress . The restricted blood flow suggests significant coronary artery disease. Angiotensin-converting enzyme (ACE) inhibitors. Thus, not surprisingly, MPI reversible abnormalities in the presence of a normal coronary angiogram have been reported in a wide variety of diseases characterized by microvessel disease such as diabetes, systemic lupus erythematosus, Behet's disease and metabolic syndrome.
