ABSTRACT

Introduction: In patients with idiopathic pulmonary fibrosis, the calculation to infer the mean pressure of the pulmonary artery with an equation involving function tests respiratory such as forced vital capacity, carbon monoxide diffusing capacity and oxygen saturation ambient air, is considered useful for the diagnosis of pulmonary hypertension, with less variability than echocardiography in relation to cardiac catheterization. Not yet been studied in other interstitial lung diseases. Objective: Estimate the agreement of the equation of pulmonary function tests with echocardiography in the diagnosis of pulmonary hypertension in patients with hypersensitivity pneumonitis. Results: In 40 patients with hypersensitivity pneumonitis by echocardiogram, 80% had pulmonary hypertension and by equation function tests respiratory the 82%; with a concordance of 0.42 (p = 0.007). Conclusions: The concordance of pulmonary hypertension by function tests respiratory equation and echocardiography was statistically significant. The oxygen saturation below 90% and carbon monoxide diffusing capacity less than 40% of predicted was associated more frequently with pulmonary hypertension diagnosed by function tests respiratory.
