The purpose of this study was to evaluate the prevalence and outcomes of pulmonary hypertension in chronic hypersensitivity pneumonitis and to examine the relationship between pulmonary function tests and pulmonary hypertension. ⋯ Using Doppler echocardiography for evaluation, pulmonary hypertension seems to be common in patients with chronic hypersensitivity pneumonitis, significantly impacts survival, and correlates with FVC, FEV(1), and PaO(2) and inversely with PaCO(2).
