Two‐Dimensional Speckle‐Tracking Echocardiography Reveals Systolic Abnormalities in Granulomatosis with Polyangiitis (Wegener’s)

BACKGROUND: Two-dimensional speckle-tracking echocardiography (STE) is a novel technique providing accurate assessment of myocardial function. However, its value in granulomatosis with polyangiitis (Wegener's) (WG) has not been studied. OBJECTIVE: To assess the presence and frequency of systolic left ventricular (LV) dysfunction using STE and to determine incremental value of STE over standard echocardiography to detect myocardial abnormalities …
