[Noninvasive methods of investigation of mammary coronary grafts and coronary vascular bed in remote period after coronary artery bypass grafting].
Aim of the present study was to investigate diagnostic value of treadmill test, stress echocardiography during exercise on treadmill as well as color duplex scanning in assessment of the state of mammary coronary grafts and coronary vascular bed in remote period after coronary artery bypass grafting. Parameters of 73 patients (70 men and 3 women) were analyzed on the average after 4.9 +/- 1.8 years after aortocoronary-mammary coronary grafting surgery. Results of examination of patients in remote terms after operations of aortocoronary-mammary coronary grafting evidence for high sensitivity and low specificity of treadmill test for lesions of mammary coronary grafts and coronary arteries. We revealed high sensitivity and specificity of stress echocardiography in diagnosis of grafts lesions including those in patients with postinfarction cardiosclerosis of anterior localization. High informativity of the method of color duplex scanning of mammary coronary grafts at rest and at the background of stress test with high dose dipyridamole in detection of grafts stenoses and occlusions was also demonstrated.
