[Diagnostic possibilities of left ventricular systolic-diastolic volume curve computed in patients with vascular diseases by means of multigated radionuclide angiocardiography].
METHODS
In this study the multigated radionuclide angiography was performed in 54 patients with and without vascular diseases; the humeral arterial pressure was measured and the BMI was calculated in each patient by mean of the weight and height. The curve expressing the variations of the sisto diastolic volume of the left ventricle was generated from an analysis of the radioisotopic angiocardiography, and the curve, the BMI and the arterial pressure were used to calculate 14 different numeric values for each patient consisting of hemodynamic parameters of the left ventricular function. The diagnosis for each patient was then examined a posteriori and the patients were divided in 15 groups of which 1 with non-cardiovascular pathologies and 14 with cardiovascular pathologies alone or in association. A statistical analysis was performed to ascertain whether the parameters could be used to classify patients into the diagnostic groups using the Fisher's discriminant analysis.


RESULTS
The obtained classification agreed in the 63% of the cases.


CONCLUSIONS
This paper proved the possibility offered by the curve expressing the changes in the sisto diastolic volume of the left ventricle to discriminate between the various cardiovascular pathologies.
