Objective: Prehypertensive individuals are at increased risk for developing hypertension and their complication. Many studies show that 2/3 prehypertensive individuals develop hypertension after 4 years. ECG and echocardiography are the routine tests used to assess LV mass. The objective of the research to determine the percentage of change in left ventricular morphology in the ECG, echocardiography, which explore the characteristics of left ventricular structural changes by echocardiography in pre-hypertensive subjects. Materials and method: We studied a total of 50 prehypertensive, 30 males (60%) and 20 females (40%), mean age 48.20±8.47years. 50 normotensive volunteers as control participants. These subjects were examined for ECG and echocardiography. Results: In prehypertensive group, with 18% of left ventricular hypertrophy on electrocardiogram, 12% of left ventricular hypertrophy on echocardiography; in the control group, we did not find any subjects with left ventricular hypertrophy. In the group with left ventricular hypertrophy, mostly eccentric left ventricular hypertrophy (83.33%), concentric left ventricular hypertrophy is 16.67%. Restructuring of left ventricular concentric for 15.9% of subjects without left ventricular hypertrophy on echocardiography. Conclusion: There have been changed in left ventricular morphology even in prehypertensive

Abstract Background Concentric left ventricular hypertrophy (cLVH) is a common left ventricular geometric pattern in patients undergoing maintenance dialysis, including peritoneal dialysis (PD). The relationship between cLVH at PD initiation and the prognosis of patients remains unclear, however. This study aimed to investigate the impact of cLVH at PD initiation on patient survival and major adverse cardiovascular events (MACE). Methods The retrospective cohort study included 131 patients who underwent echocardiography during the PD initiation period. Based on echocardiographic measurements, cLVH was defined as a condition with increased LV mass index and increased relative wall thickness. The relationship between cLVH and the prognosis was assessed. Results Concentric LVH was identified in 29 patients (22%) at PD initiation, and patient survival, MACE-free survival and PD continuation were significantly reduced in the cLVH group compared with the non-cLVH group. In the Cox regression analysis, cLVH was demonstrated as an independent risk factor of mortality (HR [95%CI]: 3.32 [1.13–9.70]) for all patients. For patients over 65 years old, cLVH was significantly associated with mortality and MACE (HR [95%CI]: 3.51 [1.06–11.58] and 2.97 [1.26–7.01], respectively). Serum albumin at PD initiation was independently correlated with cLVH. Conclusions In our study, cLVH at PD initiation was independently associated with survival in all patients and with both survival and MACE in elderly patients. Evaluation of LV geometry at PD initiation might therefore help identify high-risk patients. Further studies involving larger numbers of patients are needed to confirm the findings from this study and clarify whether treatment interventions for factors such as nutrition status could ameliorate cLVH and improve patient outcomes.

Introduction. For a patient with coronary heart disease, recovery from myocardial revascularization is a complex process. Cardiac remodeling involves, after myocardial infarction, hypertrophy and dilation, resulting in impaired systolic-diastolic cardiac function, which is an additional risk factor for events. Prospective studies have shown a relationship between left ventricular size and the risk of cardiovascular events. Given this, there was a need to conduct our research. Purpose: To determine the prevalence of types of left ventricular geometry in patients with coronary heart disease, post-infarction cardiosclerosis, depending on therapeutic tactics: revascularization or conservative therapy for 60 months. Material and Methods: We examined 101 patients aged 58.6±4.2 years after myocardial revascularization (n = 71) and with conservative treatment only (n = 30), in whom the dynamics of echocardiographic parameters of the heart were evaluated for 5 years. The values ​​of remodeling myocardial mass index of the left ventricle and the relative thickness of the left ventricle were determined. Results and Discussion. At baseline, patients with concentric left ventricular hypertrophy (50.0%) and concentric remodeling (24.1%) predominated in the main group. Normal geometry in 14.8% and eccentric left ventricular hypertrophy were observed in 11.1%. In the comparison group, eccentric hypertrophy and concentric left ventricular remodeling were most commonly observed, 29.6% each, slightly less than 25.9% concentric hypertrophy, and the least was normal geometry (14.8%). After 60 months, patients with both groups did not experience normal left ventricular geometry and concentric remodeling. The concentric type (80.0%) was predominant in the main group, and the eccentric type (55.6%) in the comparison group. Conclusions. In patients with ischemic heart disease, postinfarction cardiosclerosis progresses in 5 year follow-up myocardial hypertrophy regardless of treatment. After revascularization, concentric left ventricular hypertrophy develops more often, whereas under conservative treatment, left ventricular eccentric hypertrophy is combined with systolic dysfunction and left atrial dilatation. After revascularization, an increase in the index was associated with an increase not only in body weight but also in changes in lipid profile and diastolic hypertension.
