Associations among chronic kidney disease, high total p-cresylsulfate and left ventricular systolic dysfunction.
A significant number of patients with chronic kidney disease (CKD) have cardiac abnormalities, and left ventricular systolic dysfunction (LVSD) is a common manifestation. p-Cresylsulfate (PCS), a protein-bound uraemic retention solute, is known to cause endothelial dysfunction and possibly plays a role in coronary atherosclerosis. Furthermore, the associations among serum total PCS, major adverse cardiovascular events, all-cause mortality, and QTc prolongation have also been found in previous studies. We thus investigated the association of total PCS and CKD with LVSD in the clinical setting.. We included 403 consecutive patients with stable angina. To evaluate LV function, all patients underwent echocardiography. To measure the serum total PCS concentrations and estimated glomerular filtration rate (eGFR), blood samples were obtained.. Multiple regression analysis showed that left atrium diameter, left ventricular mass index, end diastolic interventricular septal thickness, left ventricular end-systolic diameter, left ventricular end-systolic volume, stroke volume, left ventricular end-systolic volume index, left ventricular ejection fraction (LVEF), and the interventricular septum/posterior wall of the left ventricle were independently associated with total PCS (all p<0.05). In addition, a significantly decreased LVEF was present in patients with lower and higher serum total PCS and with CKD, and with higher serum total PCS and without CKD than from those with lower serum total PCS concentrations and without CKD (p=0.004). In the multivariate logistic regression analysis, when patients without CKD and lower PCS were used as reference group, patients with the higher total PCS concentration and without CKD had an odds ratio of 3.59 for the risk of LVSD, the lower total PCS concentration and with CKD had an odds ratio of 3.89 for the risk of LVSD, and the higher total PCS concentration and with CKD had an odds ratio of 4.04 for the risk of LVSD (p=0.039, p=0.038, and p=0.020, respectively).. High serum concentrations of total PCS or CKD, or both, represent an increased risk of impaired LV systolic function in stable angina patients.

Left ventricular global longitudinal strain is associated with cardiovascular risk factors and arterial stiffness in chronic kidney disease.
Global longitudinal strain (GLS) has emerged as a superior method for detecting left ventricular (LV) systolic dysfunction compared to ejection fraction (EF) on the basis that it is less operator dependent and more reproducible. The 2-dimensional strain (2DS) method is easily measured and integrated into a standard echocardiogram. This study aimed to determine the relationship between GLS and traditional and chronic kidney disease (CKD)-related risk factors of cardiovascular disease (CVD) in patients with CKD.. A cross sectional study of patients with moderate CKD stages 3 and 4 (n = 136). Clinical characteristics, anthropometric, biochemical data including markers of inflammation [C-reactive protein (CRP)], uremic toxins [indoxyl sulphate (IS), p-cresyl sulphate (PCS)], and arterial stiffness [pulse wave velocity (PWV)] were measured. Inducible ischemia was detected using exercise stress echocardiogram. GLS was determined from 3 standard apical views using 2-dimensional speckle tracking and EF was measured using Simpson's rule. Associations between GLS and traditional and CKD-related risk factors were explored using multivariate models.. The study population parameters included: age 59.4 ± 9.8 years, 58 % male, estimated glomerular filtration rate (eGFR) 44.4 ± 10.1 ml/min/1.73 m(2), GLS -18.3 ± 3.6 % and EF 65.8 % ± 7.8 %. This study demonstrated that GLS correlated with diabetes (r = 0.21, p = 0.01), history of heart failure (r = 0.20, p = 0.01), free IS (r = 0.24, p = 0.005) free PCS (r = 0.23, p = 0.007), body mass index (BMI) (r = 0.28, p < 0.001), and PWV (r = 0.24, p = 0.009). Following adjustment for demographic, baseline co-morbidities and laboratory parameters, GLS was independently associated with free IS, BMI and arterial stiffness (R(2) for model = .30, p < 0.0001).. In the CKD cohort, LV systolic function assessed using GLS was associated with uremic toxins, obesity and arterial stiffness.
