Диагностика бессимптомной ишемической болезни сердца у больных, которым предстоят реконструктивные операции на аорте и магистральных артериях нижних конечностей

Goal of the study: working out procedure aimed at the diagnostics of painless myocardial ischemia in the patients expecting surgery on aorta and main arteries of lower limbs. Materials and methods. 72 patients with disorders of aorta and main arteries of lower limbs were enrolled into the study. Depending on factors of risk to develop cardiac vascular disorders as per Lee score they were divided into two groups. Group 1 (n = 38) included patients who had 2 and more risk factors in the pre-operative period, Group 2 included patients (n = 34) who had less than 2 risk factors. All of the patients had holter monitoring, stress echocardiography and coronary arteriography during pre-operative period. Results. The study showed the high efficiency of Lee score of cardiac-vascular complication risks. The patients who had 2 risk factors and more had hemodynamically significant lesions of coronary bed in 97.4% which was detected by coronary arteriography. In Group 2 painless myocardial ischemia was detected almost in 1/3 of patients, which later provided certain impact in the choice of surgical treatment strategy. Conclusions. The results proved low efficiency of holter monitoring in the patients suffering from multi-focal atherosclerosis and high efficiency of stress echocardiography. The latter should be mandatory included into the examination procedure of such patients regardless of the results of Lee score; and coronary arteriography is to be performed in case of 2 risk scores and more. Detection of painless myocardial ischemia can change the plan of surgical treatment and requires amending anesthesia tactics.
