  • By echocardiographic examination, LV diastolic dysfunction was evident in 35 (40%) patients. (1library.net)
  • Focused bedside echocardiography (FBE) is a valuable and increasingly available imaging modality that can be used to better manage these patients. (medscape.com)
  • We sought to divide COVID-19 patients into distinct phenotypical subgroups using echocardiography and clinical markers to elucidate the pathogenesis of the disease and its heterogeneous cardiac involvement. (bvsalud.org)
  • Uncalibrated pulse wave analysis with the Pressure Recording Analytical Method (PRAM) may be suitable to measure CO in patients with vvECMO therapy. (bvsalud.org)
  • We investigated the relationship between diastolic dysfunction and NT-proBNP levels in patients with MFS. (scipedia.com)
  • We hypothesized that diastolic dysfunction at baseline or impaired diastolic relaxation during weaning trials may mediate weaning failure. (springeropen.com)
