Kardiologiia

PURPOSE OF THE STUDYEvaluation of the value of the results of the use of cardiac functional examination methods for the stratification of the risk of developing cardiovascular complications in planned abdominal surgical interventions in patients over 65 years of age or with cardiac pathology.MATERIALS AND METHODSThe study included 179 patients over 65 years of age or with a history of heart disease who underwent elective abdominal surgery. The median age was 70 years. During the operation and for 30 days after it, cardiac complications were recorded: severe (myocardial infarction, stroke, death from cardiovascular disease), others (strokes of exertional angina, ischemic dynamics of the ST segment on the electrocardiogram - ECG - rest, paroxysmal fibrillation / flutter atrial). All patients underwent basic examination - examination, anamnesis, ECG, blood test, assessment of respiratory function, ECG monitoring. Additionally, echocardiography (EchoCG) and ergospirometry (ESM) were performed.RESULTSIn 30 (16.8 %) patients, various MTRs were detected: 6 (3.4 %) of fatal myocardial infarctions, 2 (1.1 %) of fatal strokes; 3 (1.7 %) cases of sudden cardiac death, angina attacks were recorded in 4 (2.2 %) patients, 7 (3.9 %) had ischemic ECG dynamics, 11 (6.1 %) had fibrillation episodes or atrial flutter. Chronic obstructive pulmonary disease, intervention on the colon, blood hemoglobin level 103 μmol / l, presence of any pathological changes in the resting ECG were associated with the development of SSO; according to EchoCG - VTI (linear velocity integral) in the outflow tract of the left ventricle (LV) 57 ml, global LV myocardial deformity is less than 18 %, increase in heart rate (HR) at the 1st minute load test> 27 %, peak oxygen consumption at ESM
