Aim. To assess the effectiveness of the original puncture transvenous temporary endocardial springy electrode use in patients with myocardial infarction complicated by bradyarrhythmias.Methods. The study included 126 patients with myocardial infarction complicated by acute bradyarrhythmias. The original endocardial electrode was used in 38 patients (main group). Temporary artificial heart rhythm control was performed using endocardial springy temporary puncture electrode in 88 cases of bradyarrhythmias (control group). Written informed consent was taken from all patients who underwent the procedure, and in the absence of contact with the patient decision to perform temporary cardiac pacing was made by a council of physicians.Results.. Spontaneous pacing interruption occurred in 13 patients of the main group and 32 control group patients at various times of the artificial pacing. Thanks to the used original electrode constructional features, fatal cases were prevented in 11 (84.6%) patients of the main group. In 9 of 32 patients of the control group with impaired pacemaker, cardiac pacing was restored by the electrode re-fixation to the heart right ventricular endocardium. In 23 patients of the control group artificial rhythm was restored by the method of endocardial electrode reposition. The number of patients with a spontaneous interruption of temporary artificial heart rhythm control had a strong correlation with the number of patients with the identified new changes in the electrocardiogram (ST segment elevation with acute recurrent myocardial infarction; r=0.84, pConclusion. In case of spontaneous interruption of temporary cardiac pacing caused by the loss of myocardial electrical conduction function in the area of the contact with the electrode, for effective and safe fatal cases prevention endocardial electrodes of the original design use is recommended.

Purpose  to assess the incidence of various forms of atrial fibrillation (AF) among the patients with MI, the prevalence of various types of myocardial infarction (MI) among the patients with AF, the features of the in-hospital prognosis among the patients with MI, and AF compared with those without AF. Materials and methods  1660 cases of patients with MI treated in 2013-18 - the main group (100 patients) were analyzed.  Results  AF occurred in 309 patients (18.6% of the total number of patients with MI). Preexisting AF was in 59.2% of patients. Patients with MI and AF were older than those without AF (mean age 75.2 ± 10.1 versus 64.6 ± 12.8, p <0.0001), among them there were more women (52.4% versus 35.5% in patients without AF, p <0.0001). Type 2 MI occurred 5 times more often among patients with MI and AF (p <0.0001). Further, 2 study groups were formed - the main (100 patients with type 1 MI and preexisting AF) and control (type 1 MI 200 patients without AF), adjusted for sex (58% of women in both groups), age (mean age 75.5 ± 8, 7 in the main group versus 75.2 ± 8.5 in the control group, p = 0.775). DM (45% versus 31.5%, p = 0.030), previous MI (40% versus 25.5%, p = 0.012) and stroke (21% vs. 11.5%, p = 0.037) were more common in the main group than in the control. Patients with MI and AF had lower GFR (56.8 ± 19.4 versus 61.7 ± 17.9 ml / min / 1.73 m2, p = 0.031), LDL (2.8 ± 0.9 versus 3.3 ± 1.0 mmol/L, p = 0.0002). Patients with AF had a lower left ventricular ejection fraction (55.2 ± 10.5 versus 59.8 ± 10.0 %, p = 0.0005). Significant mitral regurgitation was more common in the 1-st group (53.9% versus 30.3% in the control group, p = 0.0002). There were no significant differences in the incidence of acute heart failure (HF) (Killip 3-4) (20% versus 13%, p = 0.127). Patients in the 1-st and 2-nd groups did not differ in the number of affected coronary artery (p = 0.7327), the level of their damage (p = 0.1956), in the frequency of revascularization (p = 0.0686). Patients with MI and AF had worse in-hospital prognosis. Pulmonary embolism (PE) (9% in patients with AF versus 1% in patients without AF, p = 0.0011), minor bleeding (21% versus 9.5%, p = 0.0057), combined endpoint (stroke + PE + mortality) (19% versus 10.5%, p = 0.0415) were more common in the main group. At discharge, patients with AF had chronic HF III NYHA in 21.8% cases versus 5.5% in patients without AF, p = 0.0001. There were no significant differences in other endpoints (recurrent MI, stroke, major bleeding, and total mortality) between the groups during hospitalization. In-hospital mortality was 13% in the main versus 9.5% in the control group (p = 0.4276). Conclusion  AF occurs in 18.6% of patients with MI. Patients with AF and MI are older with the prevalence of females. Patients with type 1 MI and pre-existing AF is a group of high risk. PE, severe chronic HF, minor bleeding, and combined endpoint (stroke + PE + mortality) were significantly common among them.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction The number of patients with myocardial infarction (MI) and atrial fibrillation (AF) is increasing every year. Purpose to assess the incidence of AF among the patients with MI, the features of the in-hospital prognosis among the patients with MI and AF compared with MI without AF. Methods The patients with type 1 MI and preexisting AF have been selected from all MI patients MI admitted in 2013-18. They have formed the main group (100 patients). The control group (200 patients with type 1 MI without AF), has been created by "pair selection" method. Patients in the groups did not differ in gender, age, MI date and had not severe comorbidities. Results 1660 patients with MI were analyzed. AF occurred in 309 patients (18.6% of patients with MI). Preexisting AF was in 59.2%. Patients with MI and AF were older than MI without AF (mean age 75.2 ± 10.1 versus 64.6 ± 12.8, p <0.0001) with women’s prevalence (52.4% versus 35.5%, p <0.0001). Type 1 MI predominates among all patients. Type 2 MI occurred 5 times more often among main group (p <0.0001). 2 groups were adjusted for sex (58% of women in both groups), age (mean age 75.5 ± 8, 7 in the main versus 75.2 ± 8.5 in the control group, p = 0.775). Diabetes (45% versus 31.5%, p = 0.030), previous MI (40% versus 25.5%, p = 0.012) and stroke (21% versus 11.5%, p = 0.037) were more common in the main than in the control.

Abstract Funding Acknowledgements Type of funding sources: None. The increasing activity of the sympathetic nervous system was shown during myocardial infarction (MI). There are data that bio management application increases the vagal influences on a heart rate for patients with chronic coronary artery disease.  The purpose of this study was the assessment of changes of vegetative regulation of heart rate in patients with MI, receiving along with standard methods of treatment and rehabilitation sessions of cardiorespiratory training (KRT).  48 patients with IM in an early period of disease at the age from 40 till 70 years were surveyed. The main group was created from 29 people by whom KRT (5–10 sessions) was carried out. The assessment of efficiency and safety of KRT was carried out on a clinical picture and parameters of heart rate variability (HRV) before, after, and during KRT. The Control group consisted of 19 patients receiving only standard treatment. To exclude hyperventilation syndrome, capnometry was performed before the start of the KRT session to determine the FetCO2 individual norm for the certain patient to control the training process in a particular session. After each active sample, the concentration of carbon dioxide in the air exhaled by the patient was measured, and when it decreased below 95% of the initial value, the depth of breathing was adjusted. The use of capnometry in the study avoided adverse events during the sessions.  During carrying out of KRT, and after KRT worsening of the clinical picture at patients of the main group was not observed. HRV analysis at patients of the main group showed that after the end of KRT decrease in an index of tension (p < 0,05), an increase in an indicator of the general dispersion of heart rate (p < 0,05), and also a tendency to increase of vagal part of total power during spectral analysis (р=0,05) was observed. Normalization of heart rate and arterial pressure, growth of cardiorespiratory index, and index of a variation took place, cardiorespiratory synchronization was restored. Persons from the control group had no such changes.  Thus, the application of KRT realizing a mode of functional bio management of heart rate, as the instrument of psychophysiological support of standard medicament therapy showed the efficiency of its use in the program of rehabilitation of patients with myocardial infarction. The result of a comprehensive approach is the reduction of sympathetic and increase of vagal influences on heart rate, normalization of the main indicators of the cardiovascular system.

Endothelial dysfunction is considered one of the main mechanisms for the further development of arterial hypertension (AH) and its complications, and endothelin-1 (ЕТ-1) plays one of the key roles in this process. Endothelium is drawn into the pathological process at the earliest stages of AH development. ЕТ-1 is currently considered as a marker and predictor of the stage and consequences of AH, chronic heart failure (CHF), coronary heart disease (CHD), in particularly, acute myocardial infarction (MI), heart rhythm disorders, pulmonary hypertension, atherosclerotic vascular injury, target vascular disorders. One factor that may influence the level of ЕТ-1 is the endothelin-1 gene Lys198Asn polymorphism, which is considered by many researchers as a possible genetic marker of AH. However, the effect of this polymorphism on the level of plasma ЕТ-1 level in patients with AH of varying severity in Ukraine is understudied. The basis of this work were the materials of a complete examination of 160 patients with a verified diagnosis of AH I, stage II of 1, 2, 3 degrees (main group) and 110 apparently healthy persons (control group). Patients of the main group were divided into three subgroups: 1st group ­– 75 patients with normal body weight; 2nd group – 48 overweight patients; 3rd group – 37 patients with alimentary obesity. In obese patients, the waist circumference in women was around 103 (96–115) cm, and in men – 108 (105–116) cm, which indicates an abdominal type of obesity in these patients. As a result of the study, it was found that the level of ЕТ-1 is higher in patients with AH who suffer with overweight and obesity as compared with patients with AH and normal body weight. Also, the peptide level depends on the genotype of patients and is higher in AH patients with the genotype Asn198Asn and Lys198Asn as compared to carriers of the genotype Lys198Lys.

Background. The high prevalence of nuclear cataracts in older age groups is accompanied by a simultaneous decrease in cognitive abilities as a result of this ophthalmic disease, and other General somatic polymorbid pathology. Aim. To study the cognitive abilities of elderly and senile patients with nuclear cataracts during medical rehabilitation. Materials and methods. In clinical conditions, 68 elderly and senile patients with nuclear cataract underwent femtolaser-assisted cataract phacoemulsification with intraocular lens implantation, and in the postoperative period, medical and non-drug rehabilitation was performed (the main group). The control group con-sisted of 65 patients with nuclear cataract of the same age who also underwent the above-mentioned surgery without rehabilitation measures. The MMSE scale was used to assess cognitive impairment. Results. 9 months after surgical treatment, the cognitive status of patients in the main group improved from 17.4±0.2 to 20.7±0.3 points (p>0.05). Moderate initial cognitive dysfunction in patients of the main group changed to mild after 9 months, while in the control group it remained the same. At the same time, the proportion of patients with moderate cognitive impairment decreased significantly in the main group from 61.71±5.9% before rehabilitation to 13.2±4.1% after it was completed, and the number of patients with no cognitive deficit increased (p<0.001). In the control group, the number of patients with moderate cognitive impairment decreased from 60.0±6.0 to 46.2±6.2% (p>0.05). Conclusion. The implementation of rehabilitation measures in the postoperative period helps to improve the cognitive status of older patients with nuclear ca-taracts.

Pneumonia presents a considerable challenge in patients with cardiovascular disease due to an increase in the incidence, difficulties of diagnosis and treatment, high mortality. Aim: to study the characteristics of cardiac arrhythmias and heart rhythm autonomic regulation in patients with chronic coronary syndrome (CCS) and community-acquired pneumonia (CAP), and to define their relationship with the clinical features of the disease. Materials and methods. A monocenter cross-sectional study analyzed 90 patients with CCS in parallel groups. The main group included 60 CCS patients with CAP; the control group consisted of 30 patients without concomitant CAP. A complex clinical examination of patients was performed on 1–3 days of hospital stay in accordance with the National Recommendations. Holter ECG monitoring was performed using a CARDIOSENS K device (XAI-MEDICA, Ukraine). Results. Based on the results of 24-hour ECG monitoring, heart rhythm disorders, increased duration of myocardial ischemia and ST-segment depression depth with an increase in the total duration of tachycardia episodes within 24 hours were more common in the main group patients. The severity of CAP on the PSI/PORT scale was correlated with the 24-hour mean heart rate (r = +0.31, P < 0.05), the number of ventricular extrasystoles – with respiratory rate (r = +0.29, P < 0.05), supraventricular extrasystoles – with the duration of ST-segment depression (r = +0.57, P < 0.05). In patients with CCS and CAP, there was a decrease in the total heart rate variability (HRV), mainly in the passive period, combined with an increase in the LF/HF ratio and stress index (SI), which was directly correlated with the severity of CAP and intoxication syndrome. Conclusions. Patients with CCS and CAP are characterized by the increased 24-hour heart rate, duration of ST-segment depression, frequency of supraventricular and ventricular arrhythmias on 24-hour Holter monitoring, paroxysms of atrial fibrillation with the decreased total HRV combined with significantly increased activity of the sympathetic autonomic nervous system.

The number of patients with complicated forms of cholelithiasis of cholelithiasis is progressively growing. One of the complications of gallstone disease is Mirizzi syndrome (SM). The reason for the development of which is the spread of the inflammatory - destructive process from the gallbladder to the bile ducts with the formation of pressure ulcers in the common bile duct, as a result of which the formation of a cholecystobiliary fistula occurs, through which stones from the gallbladder enter the main bile ducts. The analysis of the surgical treatment of patients with cholelithiasis (GSD) treated in the UH NJSC "MUS" was carried out. There were 3842 patients in total, Patients were in the period from January 2012. to July 2018 The analysis revealed that of all these patients with gallstones, Mirizzi SM type III and IV syndrome was diagnosed in 25 (0.7%). In 14 (56%) patients with type III SM and type IV SM, 11 (44%). The main group consisted of 10 (40%) patients and 15 (60%) patients included in the control group. The main group completed: 1) In type III SM (only 4 (40%) patients). One patient underwent hepaticojejunostomy according to the clinic method (2017/0423.1). In 3 patients, cholecystohepaticocholedochoplasty was performed with U-shaped interrupted sutures on the drainage according to Vishnevsky (2017 / 0980.1); 2) In type IV SM (a total of 6 (60%) patients). 4 patients underwent hepaticojejunostomy according to the clinic method (2017/0423.1). In 2 patients, cholecystohepaticocholedochoplasty was performed with U-shaped interrupted sutures on the drainage according to Vishnevsky (2017 / 0980.1). The developed and tested methods of surgical treatment of Mirizzi syndrome of types III and IV make it possible to improve the immediate and long-term results of surgical treatment of patients with this pathology. These methods of surgical treatment allow preserving the physiology of the bile outflow without postoperative complications typical for traditional hepaticojejunostomy (incompetence of the anastomotic sutures, stricture of hepaticojejunostomy).

Abstract Background and introduction Metabolic syndrome (MS) is a baseline condition that influencesthe management of patients with coronary heart disease (CHD). The assessment of genotyping characteristics in patients with MS with non-ST segment elevation myocardial infarction (nSTEMI) remains a challenge. Purpose To define characteristics of G Protein β3 subunit gene C825T polymorphism; T786C in the eNOS gene and G894T in the eNOS gene in patients with MS after nSTEMI, evaluate the prognostic specificity of genotypes in a study population. Methods The study included 150 patients with CHD and MS. The main group included 99 patients (69.7% males, a mean age of (67.4±0.7 y))with nSTEMI, preserved left ventricular systolic function who underwent urgent percutaneous coronary intervention. The control group included 51 patients with a mean age of (64.6±1.3 y) without the history of previous myocardial infarction and acute cerebrovascular disease. There was no statistically significant difference between gender and age in two groups (p&gt;0.05). The predictive significance of the main group genotypes was estimated with odds ratio and risk ratio of “cumulative point of undesirable effects” (CPUE) and included: cardiovascular death, acute coronary syndrome, repeat revascularization, hospitalization for congestive heart failure. The accuracy of the genotype distribution corresponded to the Hardy-Weinberg equilibrium (p&gt;0.05). The accuracy of the results was analyzed using Student, χ2, Fisher's criteria. Results We received high patient numbers with CC genotype of eNOS:786 gene in the main group (n=19 (19.2%)) as compared with the controls (n=3 (6.2%)) (p&lt;0.05, φ=0.03), with GG genotype of eNOS:894 (p&lt;0.01, χ2=8.0) in the main group (n=59 (59.6%)) as compared with the controls (n=18 (35.3%)), with CC genotype of eNOS:894 in the control group (n=40 (78.4%)) as compared with the main group (n=56 (56.6%)) (p&lt;0.05; χ2=7.0). Patients who were heterozygous for eNOS:894 gene prevailed in the main group (n=30 (30.3%)) as compared with the controls (n=27 (52.9%)) (p&lt;0.01, χ2=7.3). The statistically significant CPUE was more frequent diagnosed in patients with TT genotype of GNβ3:825 (OR=12.00, 95% confidence interval ((CI): 2.8–51.7, p&lt;0.05), CC genotype of eNOS:786 (OR=5.1, 95% CI: 1.3–20.0, p&lt;0.05) and TT genotype of eNOS:894 (OR=8.0, 95% CI: 1.8–35.2, p&lt;0,05). Conclusions 4 practically applicable categories of reviewed genotypes were found: 1) nSTEMI - -protective: CC genotype for GNβ3:825 gene, GT – eNOS:894, 2) nSTEMI – unfavorable: CT–GNβ3:825, CC – eNOS:786 and GG – eNOS:894, 3) CPUE – unfavorable: TT – GNβ3:825, CC – eNOS:786, TT – eNOS:894, and 4) nSTEMI, CPUE-neutral: TT and TC – eNOs:786. CC – eNOS:786 genotype is separated as unfavorable for the development of both nSTEMI and CPUE. More studies are necessary for a personified approach, taken into account the obtained features of genetic associations. Funding Acknowledgement Type of funding source: Public Institution(s).

The aim – to evaluate the effect of coronary revascularization (coronary stenting, CS) on the survival of non-ST-segment elevation myocardial infarction (NSTEMI) patients during interventions at different times since the onset of the disease. Materials and methods. The study involved 101 patients with NSTEMI. 29 patients were examined urgently (from 0 to 72 h since the onset of the disease). The remaining 72 patients were hospitalized as scheduled and NSTEMI diagnosis was made between 4 and 180 days before coronary ventriculography or CS. Results and discussion. Patients after CS better tolerated physical activity, they less frequently experienced relapse of angina pectoris and myocardial infarction in comparison with the control group, in which revascularization was not performed. The overall survival of patients with NSTEMI over the 48-month observation period was statistically significantly (p<0.0048) higher in patients who underwent CS than in the control group: 95 % and 80 %, respectively. The cumulative survival without MACE of urgent and planned patients significantly (р=0.002) increased during 48 months of observation in patients who underwent CS and amounted to 78 % compared to 50 % in the control group. Also in the period from 4 to 180 days, the cumulative survival without MACE of NSTEMI patients who underwent SC in a planned manner was significantly higher compared with the control group (p<0.0036): 81 % and 50 %, respectively. In patients after percutaneous interventions, the function of the left ventricle significantly increased and after 48 months of follow-up, the number of patients without disturbances of segmental contractility increased from 82.4 % to 92.4 %. Patients with NSTEMI, who were first diagnosed with dysglycaemia (without diagnosed diabetes mellitus), were more likely to have severe multivessel coronary disease compared with patients who had normal carbohydrate metabolism. Conclusions. Carrying out CS in NSTEMI patients at different times since the onset of the disease statistically significantly increased both overall and cumulative survival of patients. At the same time, the positive effect of CS on cumulative survival without MACE was noted not only in the group of urgent patients, but also in patients who underwent NSTEMI in the period from 4 to 180 days before hospitalization.
