| الوصف: | The aim is to study the additional diagnostic possibilities of indicators obtained by digitalization of ECG in patients with ST-elevation myocardial infarction (STEMI) and stable angina (SA).Material and methods. 135 patients were examined, who were divided into groups depending on the diagnosis: 45 people with STEMI and 90 patients with SA. According to the value of the first derivative of the T wave - the maximum speed ratio (MSR) indicator, patients with STEMI were divided into two groups: group I included 25 people with MSR <0.66, group II - 20 patients with MSR ≥0.66. Patients with SA were also distinguished depending on MSR: group A included 41 patients with MSR <0.87 and group B - 49 patients with MSR ≥0.87. The results of echocardiography, Holter ECG monitoring, coronary ventriculography and digitalization of ECG based on the «Smart-ECG» medical software were evaluated.Results. In the STEMI group, significantly lower MSR values of ischemic zone were noted, compared to the group of patients with SA (0.65±0.02, Δ –25.29%, p<0.001), higher STH values in ischemic zone (0.76±0.04 mm, Δ +58.33%, p<0.001), lower left ventricular ejection fraction (LVEF) (51.96±1.21 %, Δ -9.82%, p<0.001), longer ischemia (919.00 (133, 00; 1310.00) min, Δ +3729.17%, p<0.001), lower standart deviation values of N-N intervals (SDNN) (88.11±6.65 ms, Δ -20.88%, p=0.094). Individuals with SA and MSR <0.87 showed slightly higher values of MSR in lead V2, compared to the group of SA and MSR ≥0.87 (2.51±0.08, Δ +8.19%, p=0.058). In patients with STEMI and MSR <0.66 and with SA and MSR <0.87, compared to the group with STEMI and MSR ≥0.66 and with SA and MSR ≥0.87, lower LVEF were detected (respectively (52.00 (47.75; 55.00) %, Δ -10.34%, p=0.071) and (56.73±0.83%, Δ -3.14%, p=0.088).Conclusions. Primary changes in the repolarization phase, which are inherent for patients with STEMI and SA, cause a change in the speed parameters of the differentiated ECG – reducing of MSR (more intense for patients with STEMI), ... |
