Echocardiography as a Useful Tool for Differentiating Acute Pulmonary Embolism From Acute Coronary Syndrome: A Case Report.

Both acute coronary syndrome (ACS) and pulmonary embolism (PE) are life-threatening medical emergencies with overlapping symptoms and laboratory findings. Differentiating these two emergencies and initiating proper treatment are of paramount importance for good outcomes. In this report, we present the case of a 60-year-old male with a history of seizure disorder and hyperlipidemia, who presented to the emergency department (ED) after a syncopal episode preceded by three days of brief episodes of chest pain.

The additional prognostic value of myocardial perfusion SPECT in patients with known coronary artery disease with high exercise capacity.

Background: The prognostic value of myocardial perfusion imaging (MPI) in patients with known coronary artery disease (CAD) and high exercise capacity is still unknown. We sought to determine the MPI additional prognostic value over electrocardiography (ECG) stress testing alone in patients with known CAD who achieved ≥ 10 metabolic equivalents (METs).

Methods And Results: We evaluated 926 patients with known CAD referred for MPI with exercise stress.

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.
