Aim. Study of intramyocardial stress of the left ventricle (LV) in persons exposed to occupational vibration and patients with hand-arm vibration syndrome (HAVS). Materials and methods. We examined 15 individuals exposed to vibration, 44 individuals with grade 1 HAVS, 10 individuals with grade 2. The control group consisted of 20 persons without cardiovascular pathology, who had not been exposed to hazardous occupational factors. The main occupational hazards in persons with HAVS were vibration, noise, physical exertion. Echocardiography was carried out to determine the total volume of LV (Vtotal); the volume of myocardium (Vm); myocardial mass (LVMM); myocardial mass index (LVMMI); systolic intraventricular pressure; the intensity of the functioning of the LV structures; LV circumferential and meridional diastolic and systolic stresses (σcd, σcs and σmd, σms respectively); LV tension in the circumferential and meridional direction during systole and diastole (Tcs, Tcd and Tms, Tmd respectively). Results. In persons exposed to vibration, in comparison with those who have not been exposed to occupational hazards, there is an increase in σmd by 2.5 times (p < 0.05) and σcd by 2.8 times (p < 0.05). The tension increases during systole and diastole both in the circumferential (Tcs by 17.35%, p < 0.05; Tms by 2.74 times, p < 0.05) and in the meridional (Tcd by 14.59%, p < 0.05; Tmd by 2.76 times, p < 0.05) directions. In persons with grade 1 HAVS, there is an increase during diastole σmd by 2.2 times (p < 0.05), σcd by 2.4 times (p < 0.05), and Tmd (p < 0.05) and Tms by 2.5 times (p < 0.05). In patients with grade 2 HAVS, in contrast to those with grade 1 and persons exposed to vibration, there is a change in the working conditions of LV. With the same values of Vtotal, Vm, LVMM and LVMMI, as in the described groups, in patients with grade 2 HAVS, there is a decrease by 12.3% (p < 0.05) in systolic intraventicular pressure against the background of an increase in σmd by 14.7% (p < 0.05), Tmd by 13.6% (p < 0.05), as well as σms by 2.25 times (p < 0.05) and Tcd by 1.97 times (p < 0.05). Conclusion. In the group of persons exposed to vibration and patients with grade 1 HAVS, in contrast to those who are not exposed to occupational hazards, there is an increase in stress and tension, primarily in the circumferential direction during diastole, which indicates the activation of the heterometric type of autoregulation of activity of the heart. In patients with grade 2 HAVS, stress and tension increase in the meridional direction during systole, which indicates the levelling of LV hyperfunction by isotonic type.

Background/Aim: Metabolic derangements due to increased nutritional risk lead to catabolism and loss of proteins, muscle tissue and eventually mass of parenchymatous organs. The aim of our study was to assess whether transitory nutritional risk after heart surgery influences on the left ventricle myocardial mass (LVMM), assessed by echocardiography. Methods: Consecutive sample of patients scheduled for cardiovascular rehabilitation, in period 0-3 months after surgery. Nutritional risk screening (NRS) was analyzed using the NRS-2002 tool. Results: Study sample included 330 patients after heart surgery for ischemic 186 (56.4%); valvular 91 (27.6%) and valvular plus ischemic 53 (16.1%) heart disease. Age was 65.5 ± 10.6 (range 23-84) and there were more male patients than female - 240 (72.7%) and 90 (27.3%), respectively. The percentage of unintentional loss of weight was 10.8 ± 3.4%, in range 0-23.81%, whereas NRS-2002 was 4.4 ± 1.1. LVMM was 218.7 ± 65.9 g vs. 252.3 ± 51.7 (p = 0.015); for patients with increased nutritional risk and controls, respectively. There was no significant correlation of LVMM with NRS-2002, while the percentage of unintentional loss of weight displayed only weakly inverse correlation (Rho CC = -0.197; p = 0.007). LVMM also correlated significantly with body mass index (Rho CC = 0.247; p < 0.001) and waist-to-hip ratio (Rho CC = 0.291; p < 0.001). In conclusion, LVMM was found to decrease slightly in the period of increased nutritional risk, following heart surgery. Changes in LVMM are partially consequences of systemic catabolic response, as well as anthropometric changes due to unintentional loss of weight.

Left Ventricular Noncompaction Cardiomyopathy

Cardiomyopathy or disease of the heart muscle involves abnormal enlargement and a thickened, stiff, or spongy-like appearance of the myocardium. As a result, the function of the myocardium is weakened and does not sufficiently pump blood throughout the body nor maintain a normal pumping rhythm, leading to heart failure. The main types of cardiomyopathies include dilated hypertrophic, restrictive, arrhythmogenic, and noncompaction cardiomyopathy. Abnormal trabeculations of the myocardium in the left ventricle are classified as left ventricular noncompaction cardiomyopathy (LVNC). Myocardial noncompaction most frequently is observed at the apex of the left ventricle and can be associated with chamber dilation or muscle hypertrophy, systolic or diastolic dysfunction, or both, or various forms of congenital heart disease. Animal models are incredibly important for uncovering the etiology and pathogenesis involved in this disease. This chapter will describe the clinical and pathological features of LVNC in humans and present the animal models that have been used for the study of the genetic basis and pathogenesis of this disease.

Abstract Background and Aims Pathology of the cardiovascular system is the leading cause of death in patients with CKD, while determining the causes of the formation of cardiac events is often difficult. Method We conducted an analysis of echocardiography data performed by 50 children with CKD. On the echoCG, the final systolic and diastolic sizes of the left ventricle (FSS and FDS), the final systolic and diastolic volumes of the left ventricle (FSV and FDV) were determined; measured the thickness of the interventricular septum (IVS) and the posterior wall of the left ventricle (PWLV). Left ventricular myocardial mass (LVMM) was determined by the formula proposed by R. Devereux and N. Reichek: LVMM = 1.04x (/ IVS+PWLV+FDS/3-FDS3) - 13.6where, IVS - thickness of IVS in diastole,PWLV-thickness of PWLV in diastole, FDS-final diastolic size of the left ventricle. Results We conducted an analysis of echocardiography data performed by 50 children with CKD. On the echoCG, the final systolic and diastolic sizes of the left ventricle (FSS and FDS), the final systolic and diastolic volumes of the left ventricle (FSV and FDV) were determined; measured the thickness of the interventricular septum (IVS) and the posterior wall of the left ventricle (PWLV). Left ventricular myocardial mass (LVMM) was determined by the formula proposed by R. Devereux and N. Reichek: LVMM = 1.04x (/ IVS+PWLV+FDS/3-FDS3) - 13.6where, IVS - thickness of IVS in diastole,PWLV-thickness of PWLV in diastole, FDS-final diastolic size of the left ventricle. Conclusion The mechanisms of damage to the heart and blood vessels in patients with CKD begin to function already in the initial stage of renal failure and increase as it progresses. The need to know the data of clinical, laboratory and instrumental examination methods at the terminal stage of CKD is dictated, first of all, by the possibility of exposure to them. An important stimulus for conducting an echocardiographic examination is the early detection and correction of cardiovascular disorders, in connection with the prospect of increasing the survival of patients after kidney transplantation.

Clinical Problems

Ventricular noncompaction is a kind of cardiomyopathy which is called Noncompaction Cardiomyopathy (NCC). In this condition in which the muscular wall of the main pumping chamber of the heart -the left ventricle (LV) appears to be spongy and “non-compacted”, consisting of a meshwork of numerous muscle bands called trabeculations. Here, anatomically LV wall has deep trabeculations. This condition is associated major clinical problems like systolic and diastolic dysfunction, arrhythmia and even systemic embolism. Sudden cardiac death may occur in this group. Early detection of this condition may help to plan the management. DOI: http://dx.doi.org/10.3329/uhj.v7i1.10209 UHJ 2011; 7(1): 39-41

Cardiomyopathy by loading the myocardium with iron is the cause of heart failure in patients with major beta-thalassemia. In these patients, cardiac systolic function remains normal for a long time, but when signs of heart failure appear, death may occur in the first year, so it is necessary to identify parameters to predict the patient's progress and prognosis.Materials and methods. We enrolled 62 patients with beta-thalassemia major (30 men and 32 women), mean age 29.9 ± 7.3 years. 32.2% of patients had disorders of carbohydrate metabolism, 12.9% associated hypothyroidism, and the mean ferritin was 1060.9 ± 856.6 ng / ml. Patients were evaluated echocardiographically, using tissue doppler technique to assess systolic and diastolic function. Myocardial mass was calculated using standard formulas and the type of left ventricular remodeling (LV) was thus obtained. Depending on the ferritin level, choosing the threshold value of 1000ng / ml, a group subanalysis of the ultrasound parameters of cardiac systolic and diastolic function was performed.Results. All patients had LV ejection fraction above 50% (LVEF), but longitudinal LV systolic dysfunction was observed in 19.3% of patients. Also in patients with serum ferritin values ​​above 1000ng / ml, the parameters of longitudinal systolic function of LV are affected, paradoxically the average value of LVEF being higher in these patients. About a quarter of patients had diastolic dysfunction, but 40.3% had elevated LV filling pressures. We noticed that the batch with ferritin over 1000 ng / ml associated increased LV filling pressures. The evaluation of the function of the right ventricle by tissue Doppler (S wave at the level of the free wall VD) was statistically significantly correlated with the hemoglobin value and we obtained pathological values ​​(S VD <11.5 cm / s) especially in the group with ferritin over 1000ng / ml. We noticed the presence of morphological abnormalities of LV, by increasing myocardial mass and the appearance of LV remodeling, 31% of patients showed severe forms, especially eccentric remodeling. It was observed that there is a risk of negative remodeling of the left ventricle in the group of those with ferritin above 1000ng / ml.Conclusions. The study proves that the evaluation of the systolic and diastolic function of the left and right ventricle by tissue Doppler ultrasound is much more accurate in the early detection of myocardial dysfunction. Ferritin levels above 1000ng / ml have been associated with impaired cardiac function parameters. Also, the remodeling of the left ventricle observed in this group of patients may be the first sign of heart failure.

Recent studies have shown that heart disease in patients with rheumatoid arthritis occurs according to various data in 20-100% of cases. Hypertension is often the first objectively detectable marker of cardiovascular pathology in patients with rheumatoid arthritis. Hypertension in patients with rheumatoid arthritis usually becomes an active initiator and accelerator of the progression of atherosclerosis and remodeling of the left ventricle. Cardiac remodeling in patients with hypertension and in patients with rheumatoid arthritis, combined with hypertension is a significant factor that affects to the quality of life and prognosis and requires careful study of this problem. The purpose of the work was to study the systolic function and morphological parameters of the left ventricle in patients with rheumatoid arthritis in combination with hypertension and to establish indicators associated with high cardiovascular risk. Material and methods. The main group of patients consisted of 93 patients with rheumatoid arthritis of moderate activity in combination with hypertension stage II. The second group included 45 patients with essential hypertension stage II. The control group had 31 almost healthy people. An ultrasound examination of the heart was performed with studying of systolic function and the main morphological parameters of the left ventricle. Results and discussion. We found a significant increase in the left ventricle myocardial mass index by 11.97% in patients with rheumatoid arthritis in combination with hypertension compared to the patients with essential hypertension and by 30.1% compared to the control group. We also detected the significant increase of the interventricular septum thickness by 9.02%, the posterior wall of left ventricle – by 5.51%, and the relative wall thickness of left ventricle – by 6.0% in patients with rheumatoid arthritis in combination with hypertension compared to the patient with essential hypertension. There was a significant increase in end-diastolic volume by 8.64%; end-systolic volume – by 12.95%; and a decrease of ejection fraction by 2.5% in patients with rheumatoid arthritis in combination with hypertension with m SCORE >4 points compared to the corresponding indicators of patients with m SCORE ≤4 points. The study showed that the most common type of left ventricle remodeling was concentric left ventricle hypertrophy (79% of patients) in patients with rheumatoid arthritis with hypertension. In addition, the subgroup of patients with m SCORE >4 points left ventricle myocardial mass and left ventricle myocardial mass index were by 15.01% and 14.86% significantly higher than the corresponding indicators in the subgroup of patients with m SCORE ≤4 points. Conclusion. The patients with rheumatoid arthritis in combination with hypertension showed an association between increasing of the left atrium size and the volume parameters of the left ventricle, and the presence of fluid in the pericardial cavity. This was manifested by the left atrium size increase by 10.65%, end-diastolic volume – by 8.62%, end-systolic volume – by 12.2% and the ejection fraction decrease by 2.23% in patients with fluid versus to a subgroup of patients without fluid in the pericardium
