[Non-invasive nuclear medical evaluation of left ventricular function in patients with coronary heart disease. Comparative study with the floating catheter].

In this paper there has been analysed the diagnostic value of the parameters of the diastolic function (Peak Filling Rate, PFR and Time to Peak Filling Rate, TPFR) which are not to be covered by invasive methods. To this examination we applied a recently discovered nuclear medical method: we used the Nuclear Stethoscope and with it were able to investigate not only the systolic function (Ejection Fraction) but also the diastolic function (PFR, TPFR). In addition to this we undertook a floating catheter during exercise for the critical examination of the left ventricle. The examined patients consisted of 28 patients, suffering from Coronary Heart Disease, the majority of them after myocardial infarction. In patients suffering from CHD there may be found relations between the nuclear medical parameters of the diastolic function and the pulmonary capillary wedge pressure as far as in all patients who showed a functional disturbance with the aids of invasive methods this could also be proved non-invasively.
