Physiological Profile and Limitations in Exercise in Idiopathic Pulmonary Fibrosis.

Purpose: This study aimed to describe the physiological profile and limiting factors during exercise among patients with idiopathic pulmonary fibrosis.

Methods: A descriptive study involving 34 patients with idiopathic pulmonary fibrosis (22 men) aged 68 ± 8 years was conducted. All patients completed a pulmonary function test, cardiopulmonary exercise test, Doppler echocardiography, 6-minute walk test, and modified Medical Research Council dyspnea evaluation.
