Background: Assessment of quality of life in patients with stable angina and normal gated single-photon emission computed tomography myocardial perfusion imaging (MPI) remains undefined. Symptom evolution in response to imaging findings has important implications on further diagnostic testing and therapeutic interventions.
Methods: Prospective cohort study was conducted at the University of Alabama at Birmingham enrolling 87 adult participants with stable chest pain from the emergency room, hospital setting, and outpatient clinics.
Importance: Limited data suggest that von Willebrand factor (VWF) abnormalities may accompany the high-shear state associated with prosthetic valve dysfunction. If true, laboratory testing could add value in quantifying prosthesis dysfunction and could suggest a pathophysiological explanation for acquired bleeding in some patients.
Objectives: To determine whether dysfunctional valve prostheses are associated with VWF abnormalities compared with normally functioning valve prostheses, to identify the severity of the VWF abnormality relative to other conditions, and to describe associated bleeding and the occurrence of gastrointestinal angiodysplasia.
The pericardium is characterized by a two-layer sac that surrounds the heart and provides an enclosed, lubricated space. Diseases of the pericardium may occur due to active inflammation, scar, calcification or effusion. While clinical, ECG and hemodynamic evaluation have been the established methods for the diagnosis of pericardial disease, advances in cardiac computed tomography and cardiovascular MRI provide complementary tools for diagnostic, prognostic and therapeutic assessment.
