SummaryBackgroundPulmonary hypertension (PH) is an important complication to interstitial lung disease (ILD). The aim of the present study was to investigate the prevalence and impact of PH on prognosis and exercise capacity in ILD patients.Methods212 ILD patients were screened for PH by echocardiography. Criteria for PH were either a tricuspid pressure regurgitation gradient >40 mmHg, a tricuspid annular plane systolic excursion <1.8 cm or right ventricular dilatation. If possible, PH was confirmed by right heart catheterisation. Pulmonary function tests and 6 min walk tests (6MWT) were performed.Results29 patients (14%) had PH, 16 (8%) had mild and 13 (6%) had severe PH (mean pulmonary artery pressure ≥ 35 mmHg). Compared to patients with...
