Atherosclerotic involvement of lower limbs arteries is a common disorder associated with a high risk of cardiovascular morbidity and mortality, requiring an early start of the comprehensive therapy. Typical clinical manifestations of this disease are found only in some patients that encumbers to make timely diagnosis. Determination of ankle-brachial index (ABI) is a reliable approach of the assessment of the state of blood flow in the lower extremities, but the classical technique requires the participation of specially trained personnel and expensive equipment. In the article there is discussed the use of widely available oscillometric blood pressure monitors for the determination of ABI. In a group of 39 patients with high risk of the development of atherosclerosis there was performed a comparison of the results of the determination of ABI with the help of oscillographic blood pressure monitors and ABI evaluated by the method of volumetric sphygmography. There was shown the sufficient accuracy of the determination of ABI with the aid of oscillographic blood pressure monitors and the interrelationship of this index with the risk of detection ofsignificant atherosclerotic involvement of lower limbs arteries according to Doppler ultrasound data. There was demonstrated that this method can be used at the stage of outpatient examination of patients with a high risk for atherosclerotic involvement of lower limbs arteries.

Although advancements in home-use technologies have allowed users to take control over how they monitor their health, their likely inexperience with such technologies can lead to use errors. The study aimed to determine the usability of a home-use blood pressure monitor, which included the device and instructional materials. Nineteen participants completed a 45-minute study which included an out-of-the-box handling scenario without moderator facilitation. The primary goal of this scenario was to determine if participants would be able to classify their heart rate reading obtained from the heart rate monitor as either low, average, or high in accordance to the thresholds set by the device. Although a majority of users were able to complete the use scenario, users nonetheless experienced major use errors and had difficulty with correctly placing the blood pressure cuff on their arm or inadvertently inflated the cuff when simply trying to turn on the device. There were also differences in the instructional materials such as how users should place the cuff around their arm. These inconsistencies were exacerbated by ambiguous wording without any pictorial clarifications. Additionally, 10% of users were unable to locate information on how to interpret their blood pressure readings. These findings highlight the importance of studying the usability of at-home blood pressure monitors to ensure more accurate health monitoring of users.

Background It is not clear whether risk stratification can help choose the most favourable systolic blood pressure target for primary prevention of cardiovascular events. Design A secondary analysis of Systolic Blood Pressure Intervention Trial (SPRINT). Methods To perform a secondary analysis, we obtained the data from SPRINT from the National Heart, Lung, and Blood Institute data repository centre. In SPRINT, an open-label trial, participants without diabetes with systolic blood pressure of ≥130 mmHg were randomly assigned to intensive and standard treatment groups with systolic blood pressure targets of <120 and <140 mmHg, respectively. The primary composite outcome was myocardial infarction and other acute coronary syndromes, stroke, heart failure, or death from cardiovascular causes. Here, we have analysed data from participants without cardiovascular disease and chronic kidney disease aged under 75 years categorised based on the baseline 10-year Framingham risk score (<10% (low risk); ≥10% and <15% (intermediate risk); ≥15% (high risk)). Results A total of 4298 patients were included in the analysis. With intensive treatment, there was a significant reduction in the primary outcome events in patients at high risk (0.86% per year vs. 1.81% per year; hazard ratio (HR) 0.51; 95% confidence interval (CI) 0.31 to 0.85; P = 0.010), and at intermediate risk (0.60% per year vs. 1.46% per year; HR 0.37; 95% CI 0.17 to 0.82; P = 0.014) but not for those at low risk (0.75% per year vs. 0.57% per year; HR 1.14; 95% CI 0.55 to 2.38; P = 0.714). Conclusions Intensive systolic blood pressure reduction is beneficial for primary prevention of cardiovascular morbidity and mortality in patients without diabetes with more than low cardiac risk (above 10%).

Abstract Background and aims Aortic stiffness is an independent predictor of cardiovascular morbidity and mortality and thus simple, rapid and preferably automated techniques are indispensableto persue a global approach in risk statification. A novel oscillometric based carotido-femoral pulse-wave velocity (cfPWV) was investigated, regarding diagnostic accuracy, sensitivity and specificity and with emphasis on costs, training curves and procedural time effort. Methods In a single-center crossover study, we evaluated subjects free of known cardiovascular disease (CVD) and CVD subjects and a subgroup with peripheral artery disease (PAD) undergoing ankle-brachial index (ABI) and PWV measurements using oscillometry (BoSo, Bosch + Sohn, Germany) compared to tonometry (SphymoCor, Atcor Australia). Pearson's correlation analysis was used to assess the relationship of PWV measurements for both methods. Moreover, examination times and costs were compared. Results A total of 174 study subjects underwent assessment of oscillometric and tonometric PWV measurements. CVD-free subjects (n=57) were younger (60.4±15.6 vs. 67±12.9 years, p=0.003) compared to CVD subjects (n=117). PWV measurements showed significant correlations in CVD-free subjects (r=0.797, p<0.001), in CVD subjects (r=0.817, p<0.001) and the subgroup of PAD subjects (r=0.807, p<0.001). Sensitivity, specificity, positive predictive value and negative predictive value of the oscillometric measurement for detecting arterial stiffness reached 93%, 84%, 86%, and 92%. The examination time of the oscillometric method was shorter compared to tonometry (4.4±0.5 vs. 9.2±0.8 min, p<0.001) in line with reduced costs. Conclusion Using a simple and rapid automated oscillometric method, we provide good diagnostic accuracy for the determination of aortic stiffness through PWV, both in CVD-free and in CVD subjects. This might help in terms of cost-effectiveness and simplification in daily practice to screen for cardiovascular morbidity and for vascular damage in atherosclerosis.

Abstract Background It is crucial to frequently inspect the proper operation of non-invasive electronic blood pressure monitors in various sites to prevent accidents from inaccurate blood pressure measurements, especially for large-scale hospitals. However, most conventional blood pressure monitor inspection devices are not suitable for such on-site investigation purpose. In this study, we propose a new single-pieced, fully air-driven pseudo blood pressure generator that is suitable for frequent on-site pre-screening tests of the blood pressure monitor by nurses. Results The proposed model comprises a rigid cylindrical body, two simulated brachial arteries, two air-pumps, an electronic controller, and a pressure sensor. Control algorithm based on polynomial curve fitting was implemented to generate various user-instructed systolic blood pressure and heart-rate conditions automatically. To evaluate the performance and clinical feasibility of the proposed model, various experiments were performed using ten commercial electronic blood pressure monitors. Experimental results demonstrated that the values of the Pearson coefficient between the reference pseudo-blood pressure waveforms and the actually generated pressure waveforms were 0.983, 0.983 and 0.997 at 60, 70 and 80 beats/min, respectively (p < 0.05). Besides, during the experiments using ten commercial blood pressure monitors, the maximum error in average systolic blood pressure was 2.9 mmHg, the maximum standard deviation in average systolic blood pressure was 3.5 mmHg, and the maximum percentage error in average pumping rate was 3.2%, respectively. Conclusions We expect that the proposed model can give an easy and comprehensive way for frequent on-site investigations of the blood pressure monitors by nurses, and improve the safety of patients with abnormal blood pressure, especially in most large-scale hospitals.

Objective: to evaluate the efficiency and extent of endovascular revascularization in patients with multisegment lesions in chronic obliterating diseases of the lower limb arteries.Material and methods. The outcomes of the endovascular correction of multisegment lesions of the lower limb arteries were analyzed in 10 patients. Results. After the treatment the patients revealed a statistically significant change (increase of the value) of the ankle-brachial index (ABI) (p = 0.001). The ABI value after the surgical intervention amounted to 0.81 (0.71; 0.87), which was connected with a favourable prognosis for such patients. Аccording to the established criteria, the outcomes of the interventions comprised the decrease of the degree of chronic arterial insufficiency (p < 0.01), all the patients were discharged having no clinical manifestations of critical lower limb ischemia or decreased evidence of intermittent claudication.Conclusion. The majority of patients with clinically evident ischemia of the lower limbs suffer from multisegment arterial lesion (the number of the segments exceeds 2), which entails the need of multiple corrections in one patient. Meanwhile, the evaluation of the treatment results is possible only in the postoperative period according to the indirect criteria. Therefore, during the operation there arises the need to develop a method of the objective intraoperative evaluation of the extent and efficiency of the performed correction of arterial lesions on each segment.
