Abstract

The aim of this study was to investigate subclinical LV changes in patients with maintenance hemodialysis (MHD) using three-dimensional speckle-tracking echocardiography (3DSTE) and to explore its prognostic value. A total of 88 individuals were consecutively enrolled, including 66 subjects with MHD and 22 age- and sex-matched controls. Conventional and Real-time three-dimensional echocardiography was performed and analyzed. Left ventricular volume, strain and time parameters were calculated and compared. The MHD cohort was then followed to record cardiovascular events (CVE). Univariate and multivariate logistic regression analysis was used to identify independent predictors of CVE. Compared with the controls, MHD patients had significantly lower global longitudinal and radial strain (GLS and GRS), and LVEF (GLS: -17.0 ± 2.3 vs -18.8 ± 2.3 %; GRS: 37.0 ± 3.5 vs 39.4 ± 3.4 %; LVEF: 57.3 ± 4.2 vs 59.5 ± 3.5 %, p < 0.05 for all), as well as enlarged LV volume (EDV: 51.3 ± 14.2 vs 40.4 ± 7.3 ml/m(2); ESV: 22.0 ± 6.9 vs 16.3 ± 3.2 ml/m(2); SV: 29.2 ± 8.0 vs 24.0 ± 4.7 ml/m(2), p < 0.01 for all) and LV mass index (LVMi) (107.7 ± 28.6 vs 83.7 ± 20.6 g/m(2)). Time to minimum end-systolic volume and to peak longitudinal strain (T-msv an...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
