[Indicators of central hemodynamics in patients with disorders of cardiac rhythm and conductivity and nonspecific ECG changes without organic myocardial lesions].
Pulmonary arterial diastolic pressure (PADP) and cardiac index (CI) were measured by thermodilution at rest and during sitting bicycle ergometry in 95 patients at risk for cardiomyopathy in the future. Normal parameters were recorded in 85 patients: CI increased at least 2.5-fold, and PADP was within 16 mmHg at the peak of exercise. Ten patients showed an abnormal rise of PADP up to 29.0 +/- +/- 1.2 mmHg in the presence of an adequate CI increment. This may be an early manifestation of myocardial contractility disorders.
