| Summary: | The method described, of non-invasive diagnostics of significant coronary stenosis in patients with disordered myocardial perfusion by the data of monofoton emission computed tomography of myocardium. The method includes utilization of echocardiographic parameters — index of asynergy of the left ventricle and presence of significant mitral regurgitation. It is possible to find coronary stenosis via the presence of parameters obtained with mathematic instrument of artificial neuron nets: presence of lesion (if it is convenient to talk of the presence of lesion) or absence of lesion (if the lesion is absent). Specificity of the method was 93,6%, sensitivity — 68,8%. |
