To evaluate the diagnostic and prognostic value of circulating mature and aging neutrophils in relation to hypoechoic carotid plaques and short-term progression of carotid and multifocal atherosclerosis.Material and methods. The study included 200 patients (89 males and 111 fe­males), aged 40-64 years. All patients underwent duplex ultrasound of the carotid and lower extremity arteries at the first visit and at a repeat visit after 12-24 months. Ultrasound morphology of carotid plaques was assessed using greyscale median analysis. Phenotyping and differentiation of neutrophil subpopulations was carried out using flow cytometry.Results. The absolute and relative number of mature neutrophils directly correlated with ultrasound indicators of carotid atherosclerosis, while the number of aging neutrophils — with the degree of lower extremity artery stenosis. Patients with hypoechoic carotid plaques were characterized by a significantly higher absolute number of mature neutrophils (p=0,0340). An increase in the number of mature neutrophils over 3023,0 cells/μL made it possible to predict the hypoechoic carotid plaques with a sensitivity of 75,0% and a specificity of 69,5%. Patients with carotid atherosclerosis progression had a higher absolute number of mature neutrophils (p=0,0140), as did patients with progression of multifocal atherosclerosis (p=0,0162). An increase in the number of mature neutrophils more than 3223,0 cells/μL was associated with an increase in the relative risk of polyvascular disease progression by 3,09 times (95% confidence interval, 1,34-7,17; p=0,0082) after adjustment for baseline cardiovascular disease risk.Conclusion. Among patients aged 40-64 years, increased numbers of circulating mature neutrophils are associated with an increased carotid plaque burden and hypoechoic carotid plaques. An increase in the number of mature neutrophils over 3223,0 cells/μL was associated with a 3,09-fold increase in the relative risk of polyvascular disease after adjustment for baseline cardiovascular risk.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":" May","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141127742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prospective follow-up of 260 patients with reduced left ventricular ejection fraction (age 59 (53; 66) years, 214 (82,3%) men) from the Kuzbass registry of patients with ICD. Of them, 156 (60%) patients had ischemic cardiomyopathy, while the rest had non-ischemic cardiomyopathy. The mean follow-up period was 4,2±2,3 years after ICD implantation. The following basic information about patients were assessed: demographic data, social status, history of the underlying disease, concomitant diseases, vital signs, standard clinical and paraclinical parameters, drug therapy. During the follow-up period, all cases of ADHF and death were analyzed.Results. A total of 54 (20,8%) patients died, of which 48 (88,9%) died due to ADHF. During the follow-up period, 34 patients were hospitalized for ADHF, of which 13 (38,2%) died. Thirty-five (13,5%) patients died in the prehospital stage due to ADHF that developed against the background of the underlying disease (10 (27%) had dilated cardiomyopathy, 1 (2,8%) — rheumatic mitral valve disease, 24 (68,6%) — ischemic cardiomyopathy). Thus, a total of 69 cases of ADHF were registered, which accounted for 26,5% of the total group. Mortality in general group from ADHF was 18,5%. According to the Kaplan-Meier curve, most deaths occurred during the first 1,5 years of follow-up.The regression model for predicting the ADHF risk included left atrium size (p=0,05), male sex (p=0,001), NYHA class (p=0,0001), left ventricular ejection fraction <40% (p=0,0001), no intake of renin-angiotensin-aldosterone system inhibitors (p=0,007) and amiodarone (p=0,028). The area under the ROC curve (AUC), sensitivity and specificity of the created model was 0,8, 69,2% and 80%, respectively.Conclusion. A set of routine clinical and anamnestic factors has been identified that makes it possible to predict the risk of ADHF in patients with ICDs, which must be taken into account before making a decision to implant the device. Particular attention should be paid to mandatory therapy for heart failure, as the main modifiable risk factor for ADHF.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140690055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the relationship between the presence and size of microvascular obstruction (MVO) and the prognosis of patients with ST-segment elevation acute myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) within one year.Material and methods. The study included 50 patients with a first STEMI who underwent PPCI on the infarct-related artery. After 3-7 days and 12 months, contrast-enhanced cardiac magnetic resonance imaging was performed to assess left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), and MVOs. After 12 months, patients were rehospitalized and prognosis was assessed based on data on cardiovascular events.Results. Patients with MVO had a significantly lower LVEF in the acute period of MI (44,1±10,6%) compared to patients without MVO (52,9±10,5%), p=0,0209, as well as during reassessment after a year (44,8±11,1%) compared with patients without MVO (58,9±8,0%), p=0,0004. A significant inverse correlation was found between LVEF in the initial and repeat examination and MVO size in the initial examination as follows: ρ=-0,42 (95% confidence interval (CI): -0,66 — -0,12, p=0,008) and ρ=-0,61 (95% CI: -0,78 — -0,34, p=0,0001). There was also a significant inverse correlation between LVEF and MVO size at reassessment, ρ=-0,40 (95% CI: -0,65 — -0,07, p=0,0205).

To compare the incidence of postoperative cognitive dysfunction and neuropsychological changes in the early postoperative period of coronary artery bypass grafting (CABG) in patients who underwent two versions of multitask cognitive training, which involved various cognitive and motor tasks, as well as in a control group.Material and methods. The study included 100 patients after elective CABG. All patients were randomly divided into three following groups: cognitive training (CT) 1 (postural balance combined with mental arithmetic, verbal fluency, and unusual object use tasks) (n=30), CT 2 (simple visual-motor response combined with task on mental arithmetic, verbal fluency and unusual object use) (n=35) and without training (standard postoperative therapy) (n=35).

The presence of POCD on days 2-3 was found in 100% of patients in the study groups. On days 11-12 of CABG, POCD persisted in 17 people (56,7%) from the CT 1 group, in 24 (68,6%) from the CT 2 group, and in 28 (80%) patients in the control group.

To analyze the relationship of low blood potassium concentration before surgery with the risk of postoperative atrial fibrillation (POAF).Material and methods. Data were collected and analyzed from patients admitted to the intensive care unit after cardiac surgery between January 2023 and June 2023. During the study period, 691 patients were operated on. Of these, 96 (13,9%) patients developed POAF, which made up group A (mean age 68,3±10,0). Control group B of patients with sinus rhythm was formed using a random generator and consisted of 96 patients with a mean age of 63,5±8,3.Results. The median time to onset of arrhythmia was 39,0 (29,2-51,0) hours. The blood potassium concentration one hour before surgery was significantly reduced in patients who developed arrhythmia compared with the control group (p<0,001) and averaged 3,4±0,4 mmol/L. To determine the sensitivity and specificity of the association of hypokalemia with POAF, we used a confirmatory statistical method, namely constructing ROC curves (AUC 0,640 (95% confidence interval: 0,562-0,718; p<0,001)).Conclusion. This study demonstrated the association of low preoperative blood potassium concentrations with the risk of POAF. Electrolyte concentrations alone cannot fully explain the risk of arrhythmia.

A total of 140 outpatients (men, 43%) aged 73 (67-78) years with functional class II-IV HFpEF were included in the study. The follow-up period was 34 (22-36) months.Results. LVGFI was 22,4 (19,4-24,6)%, while derivative index of LVGFI — 283,9 (248,9-332,2) ml. There were 18 (12,9%) deaths. The threshold value for predicting death for LVGFI was ≤21,4%, for derivative index of LVGFI — ≥303,6 ml. Based on cluster membership and mortality analysis, two following risk groups for death of patients with HFpEF were identified: a relatively low-risk (group 1) and moderate (group 2) risk group (mortality within 34 months ~25%). Group 1 was represented by patients, predominantly male, with class II HFpEF, coronary artery disease (CAD) and prior myocardial infarction (MI), concentric hypertrophy, a significant LV mass increase, a high frequency of bendopnea, lower LVGFI and higher derivative index of LVGFI. Group 2 was represented by patients, predominantly female, with class II HF, a history of CAD and myocardial infarction, concentric hypertrophy and concentric remodeling, a moderate LV mass increase, a relatively low frequency of bendopnea, higher LVGFI and lower derivative index of LVGFI. Based on the data obtained, an algorithm was developed to determine the risk of death in patients with HFpEF.Conclusion. LVGFI and its derivative index can be used in phenotyping patients with HFpEF. The developed algorithm for determining the death risk makes it possible to identify outpatients with HFpEF who need intensified therapy and observation by a general practitioner and cardiologist in order to reduce the risk of an unfavorable prognosis.","PeriodicalId":21389,"journal":{"name":"Russian Journal of Cardiology","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140688749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
