Abstract

In a group of 24 patients with coronary artery diseases, correlations of left ventricle end-diastolic volume (EDV), end-systolic volume (ESV), systolic volume (SV), and ejection fraction (EF) measurement results were assessed. Compared results were obtained with radiological angiography (RTG), echocardiography (USG), and radionuclide ventriculography (RNVG). In RNVG, the left ventricle volume was calculated using a geometrical method (GEO), a sample method with measurement of left ventricle position depth from a scintigraphic image (VZ1), and a sample method with assessment of left ventricle position depth from body height and body weight (VZ2). Interpersonal variability of RNVG evaluation was assessed simultaneously. Compared with RTG, the best correlation of EDV measurement was attained with GEO (r = 0.83) and VZ2 (r = 0.82). These methods correlate best also in ESV measurement (r = 0.91). The best correlation of EF values was obtained with USG, while r = 0.85 when using GEO and VZ2. A very low correlation was found in SV (r values from 0.39 to 0.50). The studied methods usually overestimate low values and underestimate higher values. To the EF value of 50 per cent corresponds in USG the value 48 per cent, in GEO and VZ2 the value 42 per cent. The values of EDV, ESV, and SV obtained with USG and RNVG correlate well with RTG, while the values of SV are, due to a low correlation, practically useless. Interpersonal variability of RNVG methods evaluation is minimal. (Tab. 6, Ref. 30.)
