Figure 3From: Early right ventricular systolic dysfunction in patients with systemic sclerosis without pulmonary hypertension: a Doppler Tissue and Speckle Tracking echocardiography study Receiver operating characteristic curve analysis for IVV - isovolumetric myocardial velocity, IVA - isovolumetric acceleration, S - peak systolic myocardial velocity and TAPSE - tricuspid annular plane systolic excursion. IVA shows the best area under the curve (0.988) to predict early systolic dysfunction.Back to article page
