title: Cardiopulmonary function in sarcoidosis.
abstract: Hemodynamics, angiocardiographic findings and lung function were evaluated in 10 patients with clinically, radiologically and histopathologically established sarcoidosis. All 10 patients had cardiac symptoms and/or abnormal ECG. Right and left heart catheterization, angiocardiography, spirometry and diffusion capacity were performed in all patients. Pulmonary hypertension was present in the two patients with stage III sarcoidosis and in 7 of 8 patients with stages I and II. Right ventricular end-diastolic pressure was elevated in 6 patients. Seven patients had findings compatible with a failing left ventricle with elevated end-diastolic pressure and/or elevated pulmonary capillary wedge pressure. None of the patients had entirely normal hemodynamic findings. Angiocardiography showed a low ejection fraction in 6 patients but no wall asynergy. Right ventricular angiography and coronary angiography were normal in all patients. Findings compatible with failure of the left and right ventricle of the heart was common in our sarcoid patients with cardiac symptoms and/or abnormal ECG. Impairment of the pulmonary function does not seem to be the only reason for the hemodynamic findings, thus indicating the possibility of myocardial sarcoidosis.
