[Measurement of pulmonary artery pressure at rest during volume loading for assessment of ventricular function in coronary artery disease (author's transl)].
Measurements of pulmonary artery (PA) pressure at rest with volume loading of the heart was carried out in a semirecumbent position by standardized positioning of the legs (Positioning test) in 44 patients with angiographically-proven severe coronary artery disease (CAD). The patients reacted differently and were accordingly assigned to one of the three following groups: Group I (23 patients) with normal PA pressures values showed normal results on ventriculography and accordingly, a normal ejection fraction. Group II (13 patients) showed a pathological increase in PA pressure by volume loading. Ventriculography showed hypo- or akinetic areas, with accordingly reduced ejection fraction already at rest. Group III (8 patients) showed pathological PA pressure values already at rest, in accordance with the ventriculographic existence of larger akinetic areas and a marked reduction in ejection fraction. Coronary morphology per se showed no correlation with PA pressure behaviour during volume loading at rest. Therefore, PA pressure measurement in the standardized positioning test can give a relatively accurate estimation of the functional state of the left ventricle, while statements about coronary morphology in CAD are not permissible.
