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.

P67 Left ventricular hypertrophy is associated with the various elements of the insulin resistance syndrome (Syndrome X) including insulin resistance, hypertension, diabetes, dyslipidemia and obesity. There is no current consensus on the correct method of adjusting left ventricular mass (LVM). Objective: To determine the variation in the relationship between left ventricular hypertrophy (LVH)and Syndrome X when LVM is adjusted for height, height 2.7 and body surface area (BSA) in a population based study. Methods:LVM was measured echocardiographically in 442 participants aged 35 to 65 years. Results: The prevalence of LVH ranged from 15.6% to 33.9% depending on adjustment method. The correlation between LVH and Syndrome X components varied by adjustment criteria and by sex. In men, LVH was only correlated with blood pressure and obesity measurements. In women, LVH was correlated with all Syndrome X components except HDL cholesterol. Regardless of adjustment method, women with Syndrome X were more likely to have LVH than those without Syndrome X, although the magnitude of the relationship varied by LVM adjustment (LVM/height 2.7 : OR 16.6, 95% CI: 6.7 41.1; LVM/BSA: OR 5.8, 95% CI: 2.6-12.9). In men, the relationship between Syndrome X and LVH was significant when LVM was adjusted for height 2.7 (OR 3.0, 95% CI: 1.4-6.7) but not when adjusted for BSA (OR 1.2, 95% CI: 0.4-3.5). Conclusions:Both the prevalence of LVH and the relationship between LVH and Syndrome X are dependent on the method used to adjust LVM. When LVM is adjusted for height 2.7 , LVH is more prevalent and the relationship with Syndrome X is stronger than when adjusted for BSA. Regardless of adjustment method, the relationship between Syndrome X and LVH is much stronger in women than men. The LVM adjustment method employed is important to take into account both in epidemiological studies and clinical practice.

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
