Abstract


The outcome of the acute period of myocardial infarction was predicted based on a statistical method using the algorithm Data Mining Decision Tree. As the input data, we used the sensitive and specific vectorcardiography indicators. We established significant prognostic markers of the outcome of the acute phase of myocardial infarction. If the age of the patient was 57 years or more, and the nerve conduction velocity in the myocardium of the high parts of the anterior left ventricular wall slowed to 6.33 mV/s, the death was predicted with an accuracy of 92.86 %. In the case of registration of an increase in the area of atrial loops over 0.188 mm2 (in BA2) with an angular divergence of QRS-P loops more 15,5° (in BA1), opening of QRS loop less than 2.834 mm (in 3 projections) and the nerve conduction velocity in the final part of T loop less than 2,338 mV/s (BA1) at different values of the angular divergence of QRS-T vector (in VA5), a favorable outcome with 97.67% accuracy was predicted in the patient.
