Abstract:

81 patients included in the study were divided into 3 groups depending on severity of coronary affection. QT dispersion (dQT) augmentation during exercise showed high sensitivity (0.97) and low specificity (0.36) in diagnostics of significant stenoses of one or two coronary arteries. Positive result of treadmill-test with ST segment depression (elevation) ≥1 mm doesn't allow differentiating significant and slight narrowing of coronary arteries. It is drawn a conclusion that negative result of dQT augmentation excludes hemodynamically significant coronary lesions with high probability. Positive result of dQT augmentation with high probability allows suspecting hemodynamically significant coronary stenoses enabling to use the method for screening.
