[Cognitive impairment in patients of cardiac surgery with senile asthenia syndrome and preastenia]. / Narusheniya kognitivnykh funktsii u patsientov kardiokhirurgicheskogo profilya s sindromom starcheskoi astenii i preastenii.

OBJECTIVE: To identify the features of the cognitive status in patients with cardiac surgery profile with senile asthenia syndrome (SAS) and preasthenia. MATERIAL AND METHODS: A study included 272 patients admitted for coronary artery bypass grafting (CABG). Screening for preasthenia and SAS in patients before surgery was performed using the Brief Battery of Physical Functioning Tests. SAS and preasthenia were detected in 15% of patients (n=41). Seventy-five patients were selected in the comparison group without asthenia. Assessment of the state of cognitive functions was carried out using screening neuropsychological scales - the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). RESULTS: The median of the MMSE score (27 [26; 28] and 28 [27; 29], p=0.04), and the MoCA score (23 [19; 25] and 25 [23; 27], p=0.0085) was significantly lower in patients with asthenia and pre-asthenia compared to patients without asthenia. According to the MoCA, about 60% of patients in the pre-asthenia-asthenia group had severe cognitive impairment, while in the group without asthenia, more than 30% of cases had normal cognitive functions (p=0.003). Significant intergroup differences were found in MoCA subtests, reflecting visuospatial skills, abstraction, verbal fluency and working memory (p=0.01-0.04). Regression analysis showed that age and physical functioning index (severity of asthenia) most significantly contributed to the basic cognitive status assessed by MoCA. CONCLUSION: Features of the cognitive status in patients of cardiac surgery with the SAS and preasthenia are impairments of visuospatial thinking, verbal fluency, abstract thinking and working memory. The MoCA was shown to be informative in determining the basic cognitive status of cardiac surgical patients. At the same time, the greatest contribution to the basic cognitive status is made by age and the indicator of physical functioning, which characterizes the degree of asthenia.

[The relationship of pathological ankle-brachial index and cognitive decline in patients after ischemic stroke]. / Sviaz' lodyzhechno-plechevogo indeksa i kognitivnykh narushenii u bol'nykh, perenesshikh ishemicheskii insul't.

AIM: To identify associations between cognitive impairment and values of ankle-brachial index (ABI) in patients after ischemic stroke at discharge from the hospital and over one-year follow-up. MATERIAL AND METHODS: The study included 375 patients with normal (n=192) and elevated (n=153) ABI who underwent ischemic stroke (IS). Neurological examination was performed using NIHSS, the Rankin scale, Barthel index, Rivermead Mobility Index at discharge from the hospital and over one-year follow-up. RESULTS AND CONCLUSION: Patients with elevated ABI had marked cognitive impairment and more severe neurological deficit compared to patients with normal ABI. Evaluation of ABI can help in predicting the development of post-stroke cognitive impairment in patients with IS.

[Stenosis of the carotid artery in women with ischemic stroke and markers of inflammation]. / Stenozy karotidnykh arterii u zhenshchin s ishemicheskim insul'tom i markery vospaleniia.

AIM: To assess the relationship between the severity of stenosis of the carotid arteries, the level of female sex hormones and markers of subclinical inflammation in women with ischemic stroke (IS). MATERIAL AND METHODS: Two hundred and eleven women (mean age 68.9±9.23 years) were examined. A history of cardiovascular disease, previous cardiovascular events, type and subtype of stroke were recorded. Neurological status was assessed using neurological scales. Atherosclerosis was diagnosed by color duplex scanning of brachiocephalic arteries and laboratory testing (estradiol, markers of subclinical inflammation). RESULTS: Carotid artery stenosis of ≥50% was found in 13.3% of patients, less severe stenosis in 36.0%. Stenosis of ≥50% was positively correlated with the level of IL-18, TNF-alpha, and negatively correlated with the level of IL-6, IL-4, and MMSE score. In dynamics, there was a decrease in the level of TNF-alpha in all groups of patients, and an increase in the IL-4 level in women with carotid artery stenosis of ≥50%. CONCLUSION: Study of the influence of markers of subclinical inflammation on the atherosclerosis progression and recurrent disorders of cerebral circulation in women with IS should be continued.

[Clinical significance of the cardio-ankle vascular index in patients with stroke]. / Klinicheskoe znachenie otsenki serdechno-lodyzhechnogo sosudistogo indeksa u bol'nykh s ostrym narusheniem mozgovogo krovoobrashcheniya.

AIM: To study the clinical significance of the cardio-ankle vascular index (CAVI) in patients with stroke. MATERIAL AND METHODS: The study included 374 post-stroke patients. The state of peripheral arteries was assessed using CAVI and the ankle-shoulder index (ASI). RESULTS AND CONCLUSION: The pathological CAVI (>9.0) was identified in 45.4% patients, the reduced ASI (<0.9) in 19.8% patients. Stressful factors of daily life, hypodynamia, lack of work, low education were characteristic of the patients with pathological CAVI and ASI compared to those with normal CAVI. The frequency of diabetes mellitus, clinical signs of peripheral atherosclerosis, chronic heart failure and atrial fibrillation was higher in these patients as well. Ischemic stroke was more frequent in patients with peripheral atherosclerosis and higher vascular wall rigidity. Assessments of CAVI and ASI are necessary in patients with ischemic stroke to identify those with higher vascular wall rigidity and peripheral atherosclerosis and to undertake targeted preventive measures.

[THE COGNITIVE STATUS OF PATIENTS WITH TYPE 2 DIABETES MELLITUS AFTER CORONARY BYPASS SURGERY].

The aim of the study was to evaluate the neuropsychological status of patients with type 2 diabetes mellitus (DM2) before and I year after coronary bypass surgery performed under conditions of artificial circulation. It included 114 patients (54 with and 60 without DM2). Prior to surgery, the patients with DM2 had positive characteristics of neurodynamics and attention. They deteriorated 1 year after coronary bypass surgery, but improved in the patients without DM2.

[Factors associated with the detection of carotid artery stenosis of different severity in ischemic stroke patients]. / Faktory, assotsiirovannye s vyiavleniem stenozov karotidnykh arterii razlichnoi vyrazhennosti, u bol'nykh s ishemiches-kim insul'tom.

Objective. To study the factors associated with the detection of carotid artery (CA) stenosis of different severity in patients with ischemic stroke (IS). Material and methods. We studied 694 patients with IS. The assessment of brachiocephalic arteries (BCA) was performed using ultrasound duplex scanning. All patients were stratified into three groups by CA stenosis severity: group 1 included patients without stenosis or with mild CA stenosis (30%), group 2 - patients with moderate stenosis (30-49%) and group 3 - patients with ≥50% stenosis. The severity of neurological deficits was evaluated with the NIH Stroke Scale (NIHSS), IS subtypes were defined according to the TOAST. Results. Patients with ≥50% stenosis were more likely to have atherothrombotic IS subtype, risk factors for stroke and pronounced "rough" neurological deficit compared to patients with mild, moderate stenosis or without it. Patients with moderate stenosis more often had cardioembolic IS subtype with mild neurological deficits, whereas the hemodynamic IS subtype with mild to moderate neurological deficits was defined in the group without stenosis. Conclusion. Detection of CA stenosis of different severity allows to identify IS patients with unfavorable prognosis and a high risk of concomitant coronary artery disease.
