Prognostic Assessment of Diabetics Using Myocardial Perfusion Imaging: Diabetes Mellitus is Still a Coronary Artery Disease Equivalent.

Background: Even though diabetes mellitus (DM) has been considered a "Coronary Artery Disease (CAD) equivalent", that is still controversial, especially in a contemporary population subject to optimized treatment.

Objective: We aimed to assess the cardiovascular risk of diabetics by myocardial perfusion scintigraphy (MPS).

Methods: Consecutive patients who underwent MPS from 2008 to 2012 were studied.

Prognostic value of a faster, low-radiation myocardial perfusion SPECT protocol in a CZT camera.

To determine the prognostic value of a new, ultrafast, low dose myocardial perfusion SPECT (MPS) protocol in a cadmium-zinc telluride (CZT) camera. CZT cameras have introduced significant progress in MPS imaging, offering high-quality images despite lower doses and scan time. Yet, it is unknown if, with such protocol changes, the prognostic value of MPS is preserved.

"Metabolically healthy" obesity: Prevalence, clinical features and association with myocardial ischaemia.

Objective: To evaluate the prevalence of the "metabolically healthy" (MH) or "metabolically unhealthy" (MU) obesity phenotypes and their association with cardiorespiratory fitness and inducible myocardial ischaemia.

Methods: Individuals without known coronary artery disease undergoing myocardial perfusion single-photon emission computed tomography (MPS) were studied. Those without dyslipidemia, hypertension, or diabetes were considered MH, and when ≥1 of these was present, MU status was considered present.
