“…Moreover, the inherent limitations of Dopplerbased assessments including the potential for significant errors in angle dependency with angulations > 20° may also limit the use of E' in assessing early diastolic function. In contrast, E'sr, as measured from 2D speckle-tracking echocardiography, has recently been used as a novel parameter to reflect LV relaxation function [47]. E'sr can discriminate between active and passive myocardial motion, and it can be used to quantify the angle independence of myocardial deformation in 2D.…”

“…2D speckle-tracking echocardiography has been used to assess E'sr, and it also has been reported to be useful in assessing LV diastolic function [47]. The original purpose of E' was to evaluate regional diastolic function, and thus it is limited with regards to assessing global diastolic function with regional functional abnormalities [48].…”

Chronic kidney disease (CKD), including end-stage renal disease (ESRD), is a public health issue worldwide, and is associated with high rates of morbidity and mortality. In addition, cardiovascular disease is a major cause of mortality in these patients. Both traditional and nontraditional risk factors associated with CKD can lead to remodeling of the myocardium and blood vessels, thereby resulting in cardiomyopathy, atherosclerosis and arterial stiffness. This can subsequently lead to ischemic heart disease, heart failure, cardiovascular death, rapid renal progression and progression to ESRD. Identifying these risk factors to allow for aggressive preventive and interventional strategies is important for the management of patients with CKD. This aim of this review was to survey the clinical outcomes of CKD using cardiac and vascular markers including echocardiographic parameters, systolic time intervals, electrocardiography, heart rate variability, ankle-brachial index, pulse wave velocity, differences between interarm and interankle blood pressure, and vascular calcification.

“…We verified that the LV mechanical parameters measured using the index beat were highly correlated with and identical to the mean values of corresponding parameters in consecutive multiple beats. Although several studies [20][21][22][23][24] reported the potential utility of using the index beat to determine LVEF and longitudinal strain, all of these studies used only one 2D cutting plane (apical four-chamber view), which does not always reflect the global function of the left ventricle. Biplane or triplane mode might overcome some limitations.…”

“…Study patients' raw echocardiographic data was recorded for offline analysis using EchoPAC version 08 (GE Vingmed Ultrasound AS). Dimensions of the LV, LVEF, LAVI, LVMI, and GLS were measured from the index beat [28,29]. As E and E' could be measured easily, the data was obtained from five beats [30] and then averaged for analysis.…”

Background/Aims: Fluid overload is common and associated with morbidity and mortality in patients with end-stage renal disease. The relationship between fluid overload and cardiac function is complex, and whether fluid overload is associated with adverse outcomes in patients undergoing hemodialysis (HD) independently of systolic and diastolic function of the left ventricle (LV) remains unclear. Methods: The present study aimed to investigate the relationship between overhydration and all-cause and cardiovascular (CV) mortality after adjusting for LV function in 178 maintenance HD patients. The relative hydration status (overhydration/ extracellular water, ∆HS) was measured using a body composition monitor, and then used to assess the fluid status. A ∆HS ≥7% was defined as fluid overload. Global left ventricular longitudinal systolic strain (GLS), and the early filling and early diastolic mitral annular velocity (E/E’) ratio were assessed using speckle-tracking and tissue Doppler echocardiography. Results: During a mean follow-up period of 2.7 years, 24 patients died, including 11 CV deaths. An increased ∆HS was significantly associated with all-cause and CV mortality in the univariate analysis. This prognostic significance remains after multivariate adjusting for GLS and E/E’ ratio for all-cause (HR, 1.123; 95% CI, 1.063–1.186; p-value < 0.001) and CV (HR, 1.088; 95% CI, 1.005–1.178; p-value =0.037) mortality. Moreover, ∆HS significantly improved the prognostic value beyond conventional clinical and echocardiographic parameters. Conclusion: A higher ∆HS was independently associated with increased all-cause and CV mortality after adjusting for systolic and diastolic function of the LV. This suggests that ∆HS may be a relevant target for improving outcomes in maintenance HD patients.
