Association between lung ultrasound B‐lines and exercise‐induced pulmonary hypertension in patients with connective tissue disease

Background Identification of elevation in pulmonary pressures during exercise may provide prognostic and therapeutic implications in patients with connective tissue disease (CTD). Interstitial lung disease (ILD) is common in CTD patients and subtle interstitial abnormalities detected by lung ultrasound could predict exercise-induced pulmonary hypertension (PH). Methods and Results Echocardiography and lung ultrasound were performed at rest and...
