Atrial fibrillation is a disturbance of heart rhythm, which is characterized by frequent contractions of atrial muscle fibers. Stable ischemic heart disease, arterial hypertension, heart failure, obesity are risk factors for progression of atrial fibrillation. Psycho-emotional stress, anxiety and depression can be the cause of atrial fibrillation paroxysm as well.          The objective of the research was to study the effect of mebicаr in the treatment of paroxysmal atrial fibrillation considering anxiety-depressive symptoms.      Materials and Methods. Observations were performed on patients with stable ischemic heart disease and co-existent paroxysmal atrial fibrillation using clinico-psychopathological research method (structured interview). The level of stress was determined on the L. Rider scale and the 10-Item perceived stress scale; the level of anxiety and depression was determined by means of the Hospital Anxiety and Depression Scale and the Patient Health Questionnaire-9. The evaluation of the free radical oxidation state was carried out using a spectrophotometric method to determine the activity of catalase, glutathione peroxidase, superoxide dismutase in the blood serum.           Results. As a result of the analysis, it was found that the higher the level of anxiety-depressive disorders, the more frequent paroxysms of atrial fibrillation. High level of stress was found in 37.50% of men (p<0.01) and 31.25% of women (p<0.05) in Group 2b. The manifestations of the clinical level of anxiety and depression in men of Group 2b (p<0.05) were detected.          Conclusions. The analysis of electrocardiogram indices showed the signs of atrial fibrillation (p<0.05), repolarization abnormalities (p<0.001), left ventricular hypertrophy (p<0.05), and the appearance of extrasystoles (p<0.001). Echocardiographic indices showed the signs of diffuse cardiosclerosis, severe left atrial dilatation (p<0.05) and reduced myocardial contractility, which was statistically confirmed. The use of anxiolytic medication – mebicar – during treatment helped significantly improve the clinical and hemodynamic parameters, which confirmed treatment effectiveness.

Ischemic heart disease refers to myocardial degeneration, necrosis, and fibrosis caused by coronary artery disease. It can lead to severe left ventricular dysfunction (LVEF ≤ 35–40%) and is a major cause of heart failure (HF). In each contraction, myocardium is subjected to a variety of mechanical forces, such as stretch, afterload, and shear stress, and these mechanical stresses are clinically associated with myocardial remodeling and, eventually, cardiac outcomes. Mitochondria produce 90% of ATP in the heart and participate in metabolic pathways that regulate the balance of glucose and fatty acid oxidative phosphorylation. However, altered energetics and metabolic reprogramming are proved to aggravate HF development and progression by disturbing substrate utilization. This review briefly summarizes the current insights into the adaptations of cardiomyocytes to mechanical stimuli and underlying mechanisms in ischemic heart disease, with focusing on mitochondrial metabolism. We also discuss how mechanical circulatory support (MCS) alters myocardial energy metabolism and affects the detrimental metabolic adaptations of the dysfunctional myocardium.

Aim: to find out whether atrial fibrillation (AF) in patients with ischemic heart disease (IHD) is related to some definite localization or extent of coronary artery lesions or type of coronary circulation. Materials and methods. We compared data of clinical, laboratory, and instrumental examination of 178 IHD patients from the Registry of coronary angiography of patients with AF (main group) and 331 patients (comparison group) selected according to propensity score matching with balancing by sex, age, body mass index, severity of chronic heart failure, frequency of myocardial infarctions, detection of arterial hypertension, and thyroid diseases. Results. The groups did not differ in terms of alcohol use, frequency of smoking, and detection of diabetes. Patients with AF compared with those without had higher mean heart rate (105±32 vs. 70±13 bpm, р<0.001), lower level of triglycerides (1.74±1.08 vs. 1.94±1.17 mmol / l, р=0.019). AF patients more rarely had class III–IV effort angina (52.9 % vs. 66.5 %, р=0.041). Rate of detection of left ventricular (LV) dilatation and index of LV asynergy in both groups were similar, but absolute dimensions and indexes of LV, left atrium, right ventricle, LV myocardial mass were higher in the AF group. Hemodynamically significant mitral regurgitation and lowering of LV contractility were more often detected in patients with AF (49.1 % vs. 18.4 %, р<0.001, and 56.2 % vs. 39.5 %, р<0.001, in main and comparison groups, respectively). Analysis of coronary angiography data showed that patients with compared with those without AF more often had right type of coronary circulation (87.5 % vs. 80.4 %, р=0.043) as well as lesions of the right coronary artery (92.1 % vs. 85.8 %, р=0.037), and less often lesions of left coronary artery trunk (16.3 % vs. 24.8 %, р=0.027). Conclusion. AF in patients with IHD is associated with right coronary artery lesions and right type of coronary circulation.

<p><b>Background:</b> The aim of the present study was to investigate the cardioprotective effects of the perioperative use of N(2)-L-alanyl-L-glutamine (GLN) in patients with ischemic heart disease (IHD) who undergo their operations under cardiopulmonary bypass (CPB).</p><p><b>Methods:</b> This double-blind, placebo-controlled, randomized study included 50 patients who underwent cardiac surgery with CPB. Exclusion criteria were a left ventricular ejection fraction <50%, diabetes mellitus, <3 months since the onset of myocardial infarction, and emergency surgery. Patients in the study group (n = 25) received 0.4 g/kg GLN (Dipeptiven, 20% solution) per day. Patients in the control group (n = 25) were administered a placebo (0.9% NaCl). The primary end point was the dynamics of troponin I at the following stages: (1) prior to anesthesia, (2) 30 minutes after CPB, (3) 6 hours after CPB, (4) 24 hours after surgery, and (5) 48 hours after surgery. Secondary end points included measurements of hemodynamics with a Swan-Ganz catheter.</p><p><b>Results:</b> On the first postoperative day after the surgery, the median troponin I level was significantly lower in the study group than in the placebo group: 1.280 ng/mL (interquartile range [IQR], 0.840-2.230 ng/mL) versus 2.410 ng/mL (IQR, 1.060-6.600 ng/mL) (<i>P</i> = .035). At 4 hours after cardiopulmonary bypass (CPB), the median cardiac index was higher in the patients in the study group: 2.58 L/min per m<sup>2</sup> (IQR, 2.34-2.91 L/min per m<sup>2</sup>) versus 2.03 L/min per m<sup>2</sup> (IQR, 1.76-2.32 L/min per m<sup>2</sup>) (<i>P</i> = .002). The median stroke index also was higher in the patients who received GLN: 32.8 mL/m<sup>2</sup> (IQR, 27.8-36.0 mL/m<sup>2</sup>) versus 26.1 mL/m<sup>2</sup> (IQR, 22.6-31.8 mL/m<sup>2</sup>) (<i>P</i> = .023). The median systemic vascular resistance index was significantly lower in the study group than in the placebo group: 1942 dyn�s/cm<sup>5</sup> per m<sup>2</sup> (IQR, 1828-2209 dyn�s/cm<sup>5</sup> per m<sup>2</sup>) versus 2456 dyn�s/cm<sup>5</sup> per m<sup>2</sup> (IQR, 2400-3265 dyn�s/cm<sup>5</sup> per m<sup>2</sup>) (<i>P</i> = .001).</p><p><b>Conclusion:</b> Perioperative administration of GLN during the first 24 hours has cardioprotective effects in IHD patients following CPB. This technique enhances the troponin concentration at 24 hours after surgery and is associated with improved myocardial function.</p>

Objective: To determine pulmonary vascular resistance (PVR) by echocardiography - Doppler and to find correlation between pulmonary vascular resistance with left ventricular EF, PAPs, TAPSE, tissue S-wave of the tricuspid valve in patients with ischemic heart disease. Subjects and Methods: We studied on 82 patients with ischemic heart disease and EF<40% including 36 females, 46 males. Patients were estimated for pulmonary vascular resistance, EF, PAPs, TAPSE, tissue S-wave of the tricuspid valve by echocardiographyDoppler. Results: 64.6% of patients are increased PVR, average of PVR is 3.91 ± 1.85 Wood units and it is increasing with NYHA severity. There are negative correlations between pulmonary vascular resistance with left ventricular ejection fraction (r = - 0.545; p <0.001), TAPSE index (r= -0.590; p <0.001) and tissue S-wave of the tricuspid valve (r = -0.420; p <0.001); positive correlation with systolic pulmonary artery pressure (r = 0.361, p = 0.001), Conclusions: Increased PVR is the primary mechanism for pulmonary hypertension and right heart failure in patients with left heart disease. Determination of PVR in patients with left ventricular dysfunction by echocardiography is important in clinical practice. Key words: Echocardiography-Doppler; Pulmonary vascular resistance; ischemic heart disease

Left bundle branch block is not a benign pathology, and its presence requires the identification of a pathological substrate, such as ischemic heart disease. Left bundle branch block appears to be more commonly associated with normal coronary arteries, especially in women. The objectives of our study were to describe the particularities of left bundle branch block in women compared to men with ischemic heart disease. Result: We included seventy patients with left bundle branch block and ischemic heart disease, with a mean age of 67.01 ± 8.89 years. There were no differences in the profile of risk factors, except for smoking and uric acid. The ventricular depolarization (QRS) duration was longer in men than women (136.86 ± 8.32 vs. 132.57 ± 9.19 msec; p = 0.018) and also men were observed to have larger left ventricular diameters. Left bundle branch block duration was directly associated with ventricular diameters and indirectly associated with left ventricular ejection fraction value, especially in women (R = −0.52, p = 0.0012 vs. R = −0.50, p = 0.002). In angiography, 80% of women had normal epicardial arteries compared with 65.7% of men; all these patients presented with microvascular dysfunction. Conclusion: The differences between the sexes were not so obvious in terms of the presence of risk factors; instead, there were differences in electrocardiographic, echocardiographic, and angiographic aspects. Left bundle branch block appears to be a marker of microvascular angina and systolic dysfunction, especially in women.

Background and Objectives: Atrial fibrillation (AF) is a frequently encountered cardiac arrhythmia which may be either symptomatic or asymptomatic. So, this study was conducted to know clinical presentation and to find out possible clinical and etiological profile of patients with AF.Material and Methods: This cross sectional study was conducted at Osh Regional Integrated Clinical Hospital, Osh Territorial City Clinical Hospital, The Kyrgyz Republic in collaboration with Janaki Medical College Teaching Hospital, Janakpurdham, Nepal. Sixty consecutive patients with AF were taken. Presenting complaints, past history, personal history was recorded. A thorough clinical examination was done, electrocardiogram, chest X-Ray posterio-anterior view, echocardiogram, thyroid function test and relevant test were done and analyzed.Results: Forty percent of the patients complained palpitation. Systemic thrombo-embolism was found in 15% of the patients. Other presenting complaints were cough, chest pain, shortness of breath, dizziness, swelling of the legs, tremors. Eighteen percent of patients presented with features of congestive cardiac failure and 30% of the patients gave history of rheumatic heart disease, 16.6% and 11.6% hypertension and ischemic heart disease respectively. Etiology-wise, rheumatic heart disease was the most common (46.6%) followed by hypertension (21.6%), ischemic heart disease (11.6%), dilated cardiomyopathy (6.6%), hyperthyroidism (5%), pneumonia (5%).Conclusion: Rheumatic heart disease, especially mitral stenosis is the most common cause of AF in this study. Systemic hypertension was next common etiology of AF, followed by ischaemic heart disease, dilated cardiomyopathy, thyroid disease. Heart failure, Systemic thromboembolism, decreased exercise tolerance are a major determinants for development of significant morbidity and mortality.Janaki Medical College Journal of Medical Sciences (2016) Vol. 4 (1): 5-12
