IPF usually affects patients 50-70 years of age. Most series report a male preponderance, with a male-to-female ratio of 2:1. Clinical features consist of progressive exertional dyspnea; the presence of interstitial infiltrates, as evidenced on chest radiographs; and physiologic evidence of restriction and impaired gas exchange on pulmonary function testing.
