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.

Clinical, scintigraphic, and angiographic predictors of oxygen pulse abnormality in patients undergoing cardiopulmonary exercise testing.

Background: The oxygen (O ) pulse curve obtained at cardiopulmonary exercise testing provides information on cardiorespiratory fitness and the presence of cardiovascular disease. O pulse abnormalities have been attributed to myocardial ischemia, among other conditions, but the predictors of abnormal O pulse curves are not completely known.

Hypothesis: Perfusion abnormalities detected by myocardial perfusion scintigraphy (MPS) may be associated with abnormal O pulse curves.
