The significance of some noninvasive methods in the objective evaluation of treatment of patients with coronary artery disease.

A measurement of STI and Bcg was used to provide an objective evaluation of the results of isosorbide dinitrate treatment of 120 patients suffering from coronary artery disease. Normalization of STI and Bcg in patients reporting subjective improvement following treatment was observed in a greater number of cases than the number with ECG normalization. Therefore, it can be concluded that after effective treatment measurement of STI AND Bcg provides a more sensitive means of objective evaluation than ECG.
