[Are central hemodynamics the decisive factor in the manifestation of chronic heart failure?].
In the past some authors revealed that data assembled during examinations of the central haemodynamics, echocardiography, subjective complaints, physical findings and load tolerance in patients with chronic heart failure are not mutually consistent. The authors examined therefore comprehensively 40 patients with different grades of cardiac failure. They revealed very loose relations between the grade of functional classification, echocardiographic and invasive haemodynamic parameters at rest on the one hand and spiroergometric indicators on the other hand. Closer relations with spiroergometric findings were obtained with values of invasive haemodynamic parameters after a load, in particular values of the cardiac index, and systemic vascular resistance. The authors conclude that for clinical manifestations of chronic cardiac failure the peripheral circulation and tissue metabolism is at least equally important as changes of central haemodynamics. Moreover, the importance of the right ventricular function and diastolic cardiac function is not sufficiently appreciated.
