Objective. To estimate the value of a subjective factor in interpreting stress echocardiography
(stress EchoCG). Subjects and methods. A total of 112 patients preliminarily diagnosed with coronary heart
disease (CHD) were examined. All the patients underwent exercise stress echocardiography and a quantitative
assay to assess local kinetic disorders using 2D strain. The investigation was analyzed by different expert
groups. Results. When the results of stress echocardiography were assessed by two experts, the sensitivity,
specificity, positive and negative prognostic value, as well as the accuracy of the method increased. When
the findings were assessed using 2D strain, the sensitivity, specificity, and overall accuracy of the
investigation results proved to be lower than those in the visual assessment of the test. Conclusion. The
investigation is recommended to be conducted by two experts, by basing not only on echocardiography. The
quantitative method for assessing local kinetic disorders using 2D strain does not exceed the results of the
traditional visual assessment of stress EchoCG data.
