“…Ригидность оценивали по следующим показателям: ТКИМ, индекс жесткости β, коэффициент поперечной растяжимости -DC, локальная СРПВ в сонной артерии -PWV. Важно подчеркнуть, что измерение ТКИМ технологией RF проводится автоматически в режиме реального времени, исключая постобработку данных и минимизируя влияние исследователя на результаты [5].…”

“…В настоящей работе оценивались как зарекомендовавшие себя маркеры сосудистого риска (кфСРПВ, ТКИМ ОСА, индекс CAVI), так и дополнительные параметры локальной и региональной жесткости, которые также могут служить в качестве скрининговых маркеров EVA. В частности, применялась ультразвуковая система с встроенной технологией высокочастотного сигнала RF, предназначенная для автоматической высокоточной оценки ТКИМ (до 1 мкм) и показателей локальной жесткости ОСА в В-режиме [5]. Программное обеспечение функции RF автоматически проводит оконтуривание стенок ОСА, исключая постобработку данных и минимизируя влияние исследователя на резуль-таты.…”

“…The following indicators were recorded: quality intima-media thickness (QIMT); stiffness index β; local systolic arterial pressure in CCA (loc Psys); local diastolic arterial pressure in CCA (loc Pdia). The above indicators of local pressure and stiffness are calculated using special software based on the level of blood pressure in the brachial artery, changes in the diameter and volume of the CCA in systole and diastole [13].…”

Background. In order to provide personalized medicine and improve cardiovascular outcomes, a method for predicting adverse left ventricular remodeling (ALVR) after ST-segment elevation myocardial infarction (STEMI) is needed. Methods. A total of 125 STEMI patients, mean age 51.2 (95% CI 49.6; 52.7) years were prospectively enrolled. The clinical, laboratory, and instrumental examinations were performed between the 7th and 9th day, and after 24 and 48 weeks, including plasma analysis of brain natriuretic peptide (BNP), transthoracic echocardiography, analysis of left ventricular-arterial coupling, applanation tonometry, ultrasound examination of the common carotid arteries with RF signal amplification. Results. Patients were divided into 2 groups according to echocardiography: “ALVR” (n = 63)—end-diastolic volume index (EDVI) >20% and/or end-systolic volume index (ESVI) >15% after 24 weeks compared with initial values; “non-ALVR” (n = 62)—EDVI <20% and ESVI <15%. In the ALVR group, hard endpoints (recurrent myocardial infarction, unstable angina, hospitalization for decompensated heart failure, ventricular arrhythmias, cardiac surgery, cardiovascular death) were detected in 19 people (30%). In the non-ALVR group, hard endpoints were noted in 3 patients (5%). The odds ratio of developing an adverse outcome in ALVR vs. non-ALVR group was 8.5 (95% CI 2.4–30.5) (p = 0.0004). According to the multivariate analysis, the contribution of each of the indicators to the relative risk (RR) of adverse cardiac remodeling: waist circumference, RR = 1.02 (95% CI 1.001–1.05) (p = 0.042), plasma BNP—RR = 1.81 (95% CI 1.05–3.13) (p = 0.033), arterial elastance to left ventricular end-systolic elastance (Ea/Ees)—RR = 1.96 (95% CI 1.11–3.46) (p = 0.020). Conclusion. Determining ALVR status in early stages of the disease can accurately predict and stratify the risk of adverse outcomes in STEMI patients.

Aim. To study conventional risk factors and arterial stiffness parameters to identify non-invasive markers of coronary atherosclerosis in patients with and without history of cardiovascular disease, with premature and physiological vascular aging.Material and methods. The study included 198 patients with coronary artery disease (CAD) and 57 healthy people. The subjects were divided into two cohorts: younger and older than 50 years. Each group included patients with newly diagnosed acute coronary syndrome with/without history of cardiovascular disease (CAD and/or hypertension). Conventional risk factors were analyzed in all subjects. Ultrasound radiofrequency of common carotid arteries (CCA), applanation tonometry, volume sphygmography were performed.Results. Analysis of arterial parameters in individuals <50 years old revealed differences between healthy people and patients with CAD. In the subgroup of patients without a history of cardiovascular disease compared with healthy people, CCA were damaged in 77% (p<0,05), aorta — in 13%, muscular arteries — in 29% (p<0,05); in patients with a history of cardiovascular disease, in 71% (p<0,05), 5% and 34% (p<0,05), respectively. In the older age group of patients with and without history of cardiovascular disease, CCA were damaged in 84% and 94% (p<0,05), aorta — in 92% and 87% (p<0,05), muscular arteries — in 42-44% (p<0,05), respectively. According to the ROC analysis, in patients <50 years old, the area under the curve (AUC) for the intima-media thickness (IMT) was 0,830, the threshold — 622,3 (p=0,000); for the beta stiffness index — 0,850, threshold — 7,01 (p=0,002); for L-/CAVI1 — 0,742, threshold — 7,3 (p=0,000). In patients >50 years of age, AUC for the IMT was 0,948, threshold — 607,5 (p=0,000); for the beta stiffness index — 0,740, threshold — 8,84 (p=0,000); for L-/CAVI1 — 0,861, threshold — 8,4 (p=0,000).Conclusion. Timely identification of atherosclerotic markers using noninvasive techniques can improve the prediction of cardiovascular events. A comprehensive non-invasive examination of the arteries with determination of IMT, beta stiffness index, and L-/CAVI1 will probably identify young people with an unfavorable absolute cardiovascular risk. .
