Pulmonary Function in Rheumatic Heart Disease and Its Relation to Exertional Dyspnea in Ambulatory Patients

Abstract
Pulmonary and cardiocirculatory function were studied in 21 ambulatory patients with rheumatic heart disease. A pattern of pulmonary function was observed which deviated from normal to a degree insufficient to account for the exertional dyspnea of these patients. The pathogenesis of this symptom is, therefore, discussed in relation to the observed cardiocirculatory abnormalities which were often pronounced.
