Background. Acute mesenteric ischemia (AMI) after cardiac surgery is a rare but serious complication associated to high mortality. The time of onset is the key point to correctly evaluate the clinical scenarios. Methods. Data from adult patients who underwent laparotomy for AMI after elective or urgent cardiac surgery were reviewed (January 2005 - December 2019) to report their anatomoclinical features in relationship to time of onset. Early events (within 48 hours) were allocated to Group 1, whereas late onsets were allocated to Group 2. Results. The incidence of risk factors for non occlusive mesenteric ischemia was higher in Group 1 (chronic renal failure 80% vs 38.8%, P <0.05, use of inotropes 60% vs 5.5%, P <0.01, early oligo-anuria requiring CRRT 80% vs 16.6%, P <0.01, prolonged ventilation 46.6% vs 5.5%, P <0.05), where a significative occurrence of postoperative de novo atrial fibrillation was noted in Group 2 (55% vs 5.5%, P <0.01). The number of patients who required bowel resection was proportionally higher in the Group 2 Conclusions. Two well distincted categories of AMI after cardiac surgery can be classified. The first consists of patients with well-known risk factors developing ischemia as a result of severe visceral hypoperfusion The second consists of patients with low comorbidity who experience late AMI as a consequence of“trigger events”, mainly de novo atrial fibrillation. This classification may be useful to better alert the medical staff to the possibility of bowel ischemia at any time after cardiac surgery, promoting early diagnosis and treatment.

<p><b>Background:</b> Postoperative atrial fibrillation (AF) following cardiac surgery is associated with an increased risk of stroke, prolonged hospitalization, and increased costs. Statin therapy is associated with a lower incidence of postoperative AF. We aimed to compare the preventive effects of rosuvastatin and atorvastatin on postoperative AF.</p><p><b>Methods:</b> This study included 168 patients undergoing elective cardiac surgery with cardiopulmonary bypass. Patients were divided into 2 groups according to treatment of statin. Group 1 (n = 96) was patients receiving atorvastatin, and group 2 (n = 72) was patients receiving rosuvastatin. Postoperative electrocardiographs (ECGs) and telemetry strips were examined for AF within postoperative period during hospitalization.</p><p><b>Results:</b> The incidences of postoperative AF were 17.9% (n = 17) in group 1 and 22.2% (n = 16) in group 2 (<i>P</i> = .48). Left ventricular end-diastolic diameter (LVEDD) and ejection fraction (EF) were not different between groups. Incidence of diabetes, hypertension, hyperlipidemia, smoking, myocardial infarction in past medical history, family history of atherosclerosis, male sex, drug use, and perioperative features were similar between groups.</p><p><b>Conclusions:</b> The present study revealed that preoperative rosuvastatin or atorvastatin treatment did not have a different effect in preventing postoperative AF.</p>

Objective. Assessment of the safety and efficacy of anticoagulant treatment in patients with nonvalvular atrial fibrillation (AF) in a multimorbidity setting.Materials and Methods. The cross-sectional study included 104 patients diagnosed with nonvalvular AF and followed in the medical facilities of Yekaterinburg. The subjects were interviewed, anthropometric measurements were made, and the risk of thromboembolic complications was evaluated using the CHA2DS2-VASc score. The Charlson multimorbidity index was calculated, and patients were divided into two groups: Group 1 with a low level of multimorbidity (not more than 5 points) and Group 2 with a high level of multimorbidity (6 points or more). The data are presented as a median and interquartile range (25%; 75%).Results.The study population included 40 males and 64 females. The median age was 71 (62.5; 80) years. The level of multimorbidity was estimated as 5 (3; 6) points. Group 1 included 64 patients, and Group 2 included 40 patients. Thirty-nine percent of the sample patients had a paroxysmal form of AF, 10% had a persistent form, and 51% had permanent AF. The group of patients with a high level of multimorbidity included more patients with permanent AF and fewer patients with paroxysmal AF as compared with a moderate level of multimorbidity (p<0.01). Anticoagulant treatment was indicated for 92 (88.5%) patients. It was administered to 70.7% of patients; 29.3% did not receive it. Among patients receiving anticoagulants, warfarin was administered to 18.5%, and new oral anticoagulants (NOACs) were administered to 81.5%. Complications were reported in 15.2% of anticoagulant treatment cases. Bleeding was reported in 21.7% of cases of warfarin administration and 12.5% of cases of NOAC treatment (p=0.32). The median number of risk factors for bleeding per patient was 5 (4; 5.5). The Charlson index and the total number of risk factors are significantly correlated (R=0.37, p<0.05).Conclusion. In real-world clinical practice in Ekaterinburg, Russia, 7 of 10 patients with AF for whom anticoagulant treatment was indicated actually received it; NOACs are prescribed four times more often than warfarin. With a higher level of multimorbidity, the risk of bleeding under the pressure of anticoagulant treatment increases; thus, NOACs should be preferred over warfarin for treatment of multimorbid patients.

Introduction: The relationship between migraine and stroke, especially in migraine with aura, has been well-established. There is emerging evidence that vasomotor symptoms (VMS) such as hot flashes, flushing and night sweats associated with menopause increases the risk of vascular events, especially in the perimenopausal period. The aim of this study was to compare vascular risk factors in perimenopausal females with and without migraine with concomitant acute ischemic stroke (AIS). Methods: In this IRB approved study, we examined patient level data using the SlicerDicer function within Epic at a large, academic, comprehensive stroke center from 1/1/2015 to 1/1/2020. Inclusion criteria included female sex, age 42-65 years, and hospital diagnosis code of AIS. Hemorrhagic stroke, TIA, vasculopathy, and endocarditis associated strokes were excluded. Perimenopausal was defined as age ≥42 and ≤65 years. Hormonal and menopausal status was not available. We compared rates of co-morbidities by ICD10 codes of subjects with and without migraine using descriptive statistics and Chi squared analysis. Results: We identified 2296 (90%) women without migraine (Group 1) and 243 (10%) with migraine (Group 2) admitted for AIS. The five most common risk factors for AIS in group 1 were hypertension (56%), hyperlipidemia (37%), diabetes (30%), obesity (23%) and atrial fibrillation (11%). VMS was coded in 8% and tobacco use 7%. In group 2 we found hypertension (50%), hyperlipidemia (42%), migraine with aura (31%), obesity (23%), diabetes (20%). VMS was coded in 14%, atrial fibrillation in 12%, and tobacco use in 6%. Group 2 patients were more likely to have VMS (p = 0.008) and less likely to have diabetes (p=0.001). There were no other significant differences identified. Conclusions: Vasomotor symptoms in menopause are a significant risk factor for AIS in perimenopausal women with migraine. VMS should be assessed for clinically and included as a risk factor for stroke, especially in those with additional vascular risk factors. Future studies should include a diverse sample to assess the impact of VMS in a heterogeneous population.

Abstract Autologous stem cell transplantation as consolidation therapy for de novo AL is able to improve long-term survival especially after second complete remission (CR). In this study, we retrospectively analyzed the karyotyping results performed in 79 out of 101 harvested autologous PBSC from 38 de novo AML patients and 8 de novo ALL in CR. We secondly, analyzed their impact on overall survival (OS) and event-free survival (EFS) post-transplant. All patients had abnormal medullar karyotype at diagnosis. We determined two groups of patients: (1) group 1 with chromosomal abnormalities in harvested PBSC included 10 AML [4 males and 6 females, median age: 53 years (45–66.5)] with at diagnosis 3 favorable, 4 intermediate and 3 unfavorable-risk karyotype ; 2 M0, 3 M2, 1 M3, 2 M4, 2 M5 according to Fab classification ; and 9 autotransplanted patients in CR1 and 1 in CR2 and (2) group 2 without any chromosomal abnormalities in harvested PBSC including 27 AML+ 9 ALL [22 males and 14 females, median age : 44 years (19–70)] ; 1 M0, 1 M1, 4 M2, 5 M3, 11 M4, 5 M5 with at diagnosis 18 favorable prognosis, 1 intermediate and 8 unfavorable-risk karyotype ; among ALL patients, 7 B ALL and 2 T ALL and at transplant, 29 autotransplant in CR1, 6 in CR2 and 1 in CR3]. Cytapheresis products collected contained a median number of 7.7x 108/Kg (5.2–17.3) and 6.79x108/Kg (1.26–16.4) mononuclear cells and 19x106/Kg (3–43) and 20.5x106/Kg (1–4O) CD34+ cells in group 1 and in group 2 respectively. All PBSC harvested were reinfused. Conditionning regimen was quite similar in the two groups and most of the patients of group 1 (60%) and group 2 (70%) received cyclophosphamide and TBI. The hematopoietic reconstitution was similar in the 2 groups [neutrophiles > 0.5 G/l: 26 days in group1 versus 19 days in group 2 (p=0,86)]. At 3 years after transplant, there was a trend for a better OS (54.7% CI 95% 40–74.8) (p=0.06) and EFS (52.5% 95%CI 39.6–74) (p=0.05) in patients who received PBSC without any chromosomal abnormalities compared to patients receiving PBSC with abnormal karyotype (OS : 30% 95% CI 11.6–77.3 ; EFS : 30% 95% CI 11.6–77.3). In conclusion, results observed from autologous harvested PBSC karyotyping are promising but a larger number of patients and a longer follow-up could enable to reach a more important significance.

Abstract Background Progression from paroxysmal (PAF) to persistent atrial fibrillation (PerAF) following effective PV isolation (PVI) has important clinical implications, as it is relevant for subsequent management of the arrhythmia. Objective We evaluated risk factors responsible for progression of PAF to PerAF following successful PVI. Methods Consecutive AF patients that received their first catheter ablation as well as the first redo at our center were identified (n=1352). Patients were included in group 1 if the diagnosis was PAF at both first and redo procedure (PAF to PAF) and group 2 if PAF at index progressed to PerAF at redo. All patients received PVI plus isolation of LA posterior wall and SVC at the first procedure. Results A total of 822 patients remained as PAF at redo, whereas 530 (39%) progressed from PAF to PerAF. Clinical characteristics of the study population are presented in table 1. In multivariate analysis, BMI (OR 1.02, 1.01–1.04, p=0.04), hypertension (1.4, 1.08–1.8, p=0.01), heart failure (1.67, 1.03–2.69, p=0.03), LA size (2.75, 2.29–3.31, p&lt;0.001) were independent predictors of progression of PAF to PerAF. Data on serum-transthyretin level was available for 37 and 48 patients in group 1 and 2 respectively. It was &lt;18 mg/dL (normal) in 33 (68.7%) patients in group 2 vs 6 (16.2%) in group 1 (p&lt;0.001). Conclusion In our patients, after successful PVI, progression of PAF to PerAF was mediated by independent risk factors such as high BMI, heart failure, hypertension, larger LA size and lower LVEF.

Aim. To evaluate the influence of cardiovascular risk factors on antihypertensive therapy (AHT) efficiency escape (EE). Subjects and methods. Data on 59 patients with grades 1—3 hypertension (Stages I—II) were analyzed. During chosen AHT, 24-hour blood pressure monitoring was done at baseline, 1 and 3 months after beginning the observation to identify/rule out the AHT EE phenomenon. Results. The AHT EE group (Group 1) as compared with the group that needed no therapy correction within 3 months (Group 2) was observed to have the following: elevated fasting blood glucose levels (FBGL) (5.8±0.8 vs 5.3±0.7 mmol/l; p=0.008) and higher impaired glucose tolerance (IGT) rates (8 (27.6%) vs 4 (13.3%) cases (p=0.03)); a more number of smoking patients (8 (27.6%) vs 3 (10%) cases; p=0.02); a larger number of patients with a compromised family history of cardiovascular diseases (17 (58.6%) vs 11 (36%); p=0.02). Furthermore, in Group 1 baseline average systolic blood pressure during 24 hours (SBP-24) proved to be higher than that in Group 2 (127.4±4.2 vs 122.4±6.8 mm Hg; p=0.002). Odds ratio (OR) for developing the EE phenomenon increased by 60% with a rise of 0.5 mmol in FBGL (OR, 1.60; 95% confidence interval (CI), 1.06 to 2.4; p=0.02) and by 18% with an increase of 1 mm Hg in baseline SBP-24 (OR, 1.18; 95% CI, 1.05 to 1.33; p=0.004). Multivariate analysis indicated that the independent predictors of AHT EE were a compromised family history (OR, 3.7; 95% CI, 1.1 to 12.1; p=0.03) and IGT (OR, 4.1; 95% CI, 1.02 to 16.4; p=0.04). Conclusion. AHT EE was influenced by FBGL, IGT, smoking, a compromised family history, and baseline SBP-24 level.

Introduction. Polypharmacy and the administration of potentially non-recommended drugs are the causes of adverse drug reactions. The absence of potentially recommended drugs leads to a decrease in the duration and quality of life, an increased risk of complications from various organs and systems.The purpose of the study. To analyze the structure of prescribed drugs in patients over 65 years of age with atrial fibrillation (AF) and chronic kidney disease (CKD) stages 3 and 4 for the presence of рolypharmacy and compliance of prescriptions with the criteria STOPP/START.Materials and methods. 125 case histories were analyzed in patients 65 years and older with AF and CKD. Patients were divided into two groups: group 1 – patients with AF and CKD 3a (n = 51; 84.3 % of women; mean age 86.1 ± 6.4 years; mean score on the CHA(2) DS(2)-VASc scale 6.2 ± 1.1 points; mean score on the HAS-BLED scale 3.00 ± 0.68 points); group 2 – patients with AF and CKD 3b and 4 stages (n = 39; 84.6 % of women; mean age 87.9 ± 4.7 years; mean score on the CHA(2) scale; DS(2)-VASc 6.1 ± 1.2 points; the average score on the HAS-BLED scale is 3.10 ± 0.71 points). All 100 % of patients in both groups had a high risk of stroke on the CHA(2) DS(2)-VASc scale (≥ 2 points for men; ≥ 3 points for women), 82.4 % of patients in group 1 and 79.5 % of patients in group 2 had a high risk of bleeding on the HAS-BLED scale (≥ 3 points). According to the prescribing sheets of medical histories, the frequency of polypharmacy was evaluated, as well as the structure of drug prescriptions according to the STOPP/START criteria.Results. The number of patients who were prescribed ≥5 drugs was 100 % in group 1 and 94.9 % in group 2. The number of patients receiving ≥10 drugs at the same time was 11.8 % and 20.5 % in group 1 and 2, respectively. In 64.7 % of patients from group 1 and in 53.8 % of patients from group 2, potentially non-recommended but prescribed drugs (STOPP) are present in the prescribing lists. At the same time, 96.1 % and 100 % of patients in groups 1 and 2, respectively, were not prescribed drugs that are recommended for elderly patients (START criteria).Conclusion. Patients with AF and CKD aged 65 years and older are often prescribed potentially non-recommended drugs that significantly reduce the quality of life and increase the risk of adverse drug reactions. These patients were also often not prescribed potentially recommended drugs that are necessary to improve the prognosis, reduce the risk of complications, and reduce the number of hospitalizations. The revealed facts dictate the need to optimize pharmacotherapy in elderly and senile patients with AF and CKD in a hospital setting.

Abstract Background A typical left atrial flutter (LAFL) may occur as a proarrhythmic complication of ablation for atrial fibrillation (AF). Objective We evaluated the risk factors and the best ablation strategy for LAFL in patients with no prior AF ablation. Methods Consecutive patients undergoing first catheter ablation for AFL with no prior procedure for AF were included in this prospective analysis. Based on the ablation strategy, patients were divided into, Group 1: PVI+ Flutter ablation (ablation of re-entry circuits) and Group 2: PVI+ Non-PV trigger ablation (targeting areas of focal activity as triggers). 3-D mapping of the LA was performed during tachycardia to identify the reentrant circuit. PV isolation was performed in all patients. In group 1, ablation line was chosen to transect the area critical for the circuit (roof and mitral line). In group 2, ectopic beats arising from extra-PV foci detected by isoproterenol challenge were ablated. Off-drug success rate was assessed in all. Results A total of 92 and 90 patients were included in group 1 and 2 respectively. Baseline characteristics are provided in table 1. Pre-existent LA scar was detected in 91.3% and 90% of patients in group 1 and 2 respectively. At 2 years of follow-up, 11/92 (12%) from group 1 and 60/90 (66.7%) from group 2 remained arrhythmia-free off-drugs (p&lt;0.001). In the multivariate analysis, PVI +flutter ablation was detected to be associated with significantly high risk of recurrence [HR: 3.92 (95% CI: 2.52–6.1, p&lt;0.001)] Conclusion In this series of patients presenting with LAFL with no earlier AF ablations, pre-existent left atrial scar was detected in majority of cases and PVI+ non-PV trigger ablation provided significantly better success rate than PVI+ flutter ablation.

Aim. To determine the adherence to treatment of patients with arterial hypertension (AH) and chronic obstructive pulmonary disease (COPD) against the background of complex therapy.Materials and methods. We examined 56 patients with stage II hypertension in combination with COPD. Men accounted for 70%, women – 30%. The average age of patients is 52.9±0.46 years. The patients were prescribed a fixed combination of antihypertensive drugs – telmisartan 40 mg with amlodipine 5 mg and COPD therapy according to GOLD. Patients of group 1 (n=30) studied at a health school against the background of drug treatment, patients in group 2 (n=26) did not attend a health school.Results. After 6 months of treatment, the number of patients in group 1 increased (p=0.001) regularly taking antihypertensive drugs, 96.7% of patients began to independently control blood pressure and keep a diary of a patient with hypertension. Patients of group 2 showed a statistically significant increase in the level of awareness of the presence of the disease and the awareness of patients about the risk factors for the development of the disease (p=0.01), although the number of patients controlling blood pressure remained low (p=0.1). In group 1, there was a positive trend in terms of the main risk factors, in group 2 the frequency of the prevalence of risk factors practically did not change. By the 6th month of therapy, all patients in group 1 achieved the target blood pressure, in group 2 – in 73.1% of patients. By the end of the observation, in patients of group 1, against the background of the chosen treatment tactics, there was a significantly more significant decrease in left ventricular mass index (LVMI) with its normalization in 33.3% of patients, indicating regression of LV hypertrophy (p=0.01), as well as a significant increase in the ratio of peak velocities on the mitral valve (E/A), (p=0.01), indicating an improvement in LV diastolic function. In group 2, antihypertensive therapy showed a moderate decrease in LVMI (p=0.1) with normalization of this indicator in only 2 (7.7%) of patients. By the 6th month of treatment, an improvement in the parameters of bronchial patency was revealed, however, in the 2nd group of patients, the changes in these parameters were statistically insignificant.Conclusion. The effectiveness of the treatment of hypertension and COPD depends not only on the choice of the optimal treatment tactics, but also on the patient's compliance with the prescribed therapy regimen. The results obtained indicate a positive effect of the chosen complex treatment regimen on the functional parameters of the left ventricle and bronchial patency.
