The aim of the study was to evaluate diagnostic accuracy of stress echocardiography (stress echoCG) with combination of high doze АТР and atrial pacing in diagnosis of late coronary shunts stenosis. 48 men aged from 45 to 64 (48,4 ± 1,6 years), 36 patients undergone mammarocoronary shunting, 12 patients undergone auto venous shunting. Stress echoCG with combination of high doze ATP and atrial pacing suggested shunts lesions in 44 patients, in 8 cases previously intact coronary arteries, approved with coronary angiography. Coronary angiographies reviled no coronary lesions in 24 patients > 70 % shunts restenosis, in 22 coronary stenosis from 50 up to 70 %. Accuracy, sensitivity and specificity of stress- EchoCG with combination of stress-agents in coronary shunts restenosis, as well as stenosis of previously intact coronary arteries were 100 %.
