A) 5% of diabetics have ischemia on their MPI scans.
B) Patients without myocardial ischemia are at a low annual risk, irrespective of the presence of fixed defects.
C) Defects seen on MPI do not translate into cardiovascular events.

Correct answer is B)

Diabetics are considered a high risk population for having coronary disease. The medical literature suggests that up to 20% of asymptomatic patients with diabetes have ischemia on their MPI scans.

The presence of reversible defects on MPI is associated with annual cardiac event rates ranging from approximately 3% to 10%, in different diabetic populations.
