Comparative StudyRight Ventricular Systolic Function Responses to Acute and Chronic Pulmonary Hypertension: Assessment with Myocardial Deformation.
The distinction between right ventricular (RV) dysfunction due to an acute etiology (pulmonary embolism [PE]) or chronic afterload (pulmonary arterial hypertension [PAH]) has important therapeutic implications. The aim of this study was to test the hypothesis that RV remodeling would alter RV free wall strain (RVFWS) and differentiate chronic from acute RV afterload. ⋯ RVFWS is more predictive than RV end-diastolic area and less variable than FAC in distinguishing acute from chronic RV pressure overload. RVFWS adds incremental and independent information to standard measures of RV function in assessing the acuity of pulmonary hypertension.
