Objective. To analyze the clinical and instrumental picture of the disease in patients with endovascular intervention and without indications for it. Methods. The article presents an analysis of the medical documentation of patients admitted to the Cardiology Department No. 2 of the Clinical Emergency Hospital (Smolensk). Results. The subjects most often reported unstable angina (56.4%), previous myocardial infarction (37.2%), and aortic atherosclerosis (23.6%). Endovascular intervention was performed in 60% of patients, diagnostic coronary angiography (CAG) – in 29%. When conducting echocardiography, aortic thickening was detected in 92% of patients who subsequently underwent endovascular surgery, in 67% of patients with diagnostic coronary angiography, and in 50% of patients without surgical interventions. Conclusion. Hospitalization was more often carried out for unstable angina, myocardial infarction in combination with arterial hypertension and cerebral atherosclerosis. Most of the patients underwent surgery. Aortic thickening and left atrial hypertrophy were identified by echocardiography in all groups of patients.
