Key result
Noninvasive imaging techniques, particularly myocardial perfusion scintigraphy and coronary calcium scoring, are useful for the early detection and risk stratification of silent myocardial ischemia in asymptomatic diabetic patients.
A stepwise diagnostic algorithm using ergometry, coronary calcium scoring, and myocardial perfusion scintigraphy can help detect silent ischemia in asymptomatic diabetic patients.

Supports noninvasive imaging for silent ischemia screening in asymptomatic diabetes; leaves open need for outcome trials before routine adoption.
Cardiovascular disease is the main cause of death for diabetics, and in many cases its presence is silent due to cardiac autonomic neuropathy. Thus, early diagnosis of coronary disease is essential, permitting proper risk stratification and appropriate therapy. This paper examines the usefulness of several noninvasive imaging techniques to study cardiovascular diseases in individuals with diabetes mellitus, with emphasis on nuclear cardiology, and proposes a diagnostic algorithm for detection of silent ischemia.

Amalia Peix (2013) conducted a review in Diabetes mellitus and silent myocardial ischemia. Nuclear cardiology techniques (Myocardial perfusion scintigraphy, gSPECT) was evaluated. Noninvasive imaging techniques, particularly myocardial perfusion scintigraphy and coronary calcium scoring, are useful for the early detection and risk stratification of silent myocardial ischemia in asymptomatic diabetic patients.
