Objectives: Development of pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc) represents one of the most serious complications. The study aimed at assessing right ventricular (RV) global longitudinal strain and its relation to pulmonary artery pressure.
Methods: Echocardiography was performed in 74 patients of whom 60 had SSc and 14 had mixed connective tissue disease (MCTD). Besides routine left and right ventricle assessment and pulmonary pressure estimation by Doppler echocardiography, RV fractional area change (FAC) and 2D strain of the RV free wall were evaluated. At the same time, levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), troponin T and auto-antibodies were measured and all patients had diffusing capacity of the lung for carbon monoxide (DLCO) determined. All patients with probable PAH underwent right.. View More»
