Physiologic Abnormalities of Cardiac Function in Progressive Systemic Sclerosis with Diffuse Scleroderma

Abstract
To investigate cardiopulmonary function in progressive systemic sclerosis with diffuse scleroderma, we studied 26 patients with maximal exercise and redistribution thallium scans, rest and exercise radionuclide ventriculography, pulmonary-function testing, and chest roentgenography.
