[Results of the complex evaluation of scintigraphy of the intracardiac space in patients with coronary disease].

With the help of the comparison of the results of 95 patients with coronary heart disease who were examined by means of the intracardiac space scintigraphy for the purpose of the subjective subdivision according to the NYHA-classification there is no close correlation between the nuclear-medically obtained functional sizes (EF, maximum ejection and filling rate) and the clinical degree of severity of the disease. Only at the degree of severity 3 and 4 a discrimination is possible. In 64 patients laevocardiographic and coronarographic, respectively, findings were present. The trend to the deterioration of the functional parameters and to the increase of the nuclear-medically recognizable disturbances of the kinetics, respectively, with a more intensive expression of the vascular stenoses is distinctly readable. From the examination in rest in the individual case no statement is possible concerning the findings which are to be expected in the invasive diagnostics. When there are discrepancies between the result of the intracardiac space scintigraphy and the clinical and electrocardiographic preliminary investigations in many cases a clarification becomes possible by the immediately following study under submaximal exercise. On the assumption of a close cooperation with experienced cardiologists the relatively little expensive intracardiac space scintigraphy which does not stress the patient provides an essential evidence for the prognosis and estimation of the functional capacity of the patients with coronary heart disease.
