Background: It is well known that both pressure and volume overloads contribute to left ventricular hypertrophy (LVH) and left ventricular dilatation in patients with chronic kidney disease (CKD). Few studies have evaluated the association between increased pulse wave velocity (PWV) and LVH in CKD patients not yet receiving dialysis. The purpose of this study was to assess the relationship between arterial stiffness and cardiac remodelling in patients with CKD, and to determine the independent factors associated with increased left ventricular mass index (LVMI) and left ventricular volume index (LVVI). Methods: This cross-sectional study included 96 patients with CKD. Echocardiography and measurement of arterial stiffness by PWV were performed. Clinical and echocardiographic parameters were compared and analysed. Results: Associated with the increase of PWV, there were significant trends for progressive increase in LVMI, LVH, LVVI, left ventricular dilatation and left atrium in CKD patients. Multivariate regression analysis revealed that decreased PWV, in addition to increased haemoglobin and the use of β-blocker, was an independent determinant associated with decrease in LVMI and LVVI. Conclusion: Our study demonstrated the progressive structural remodelling of left ventricle and left atrium in CKD patients associated with increased severity of arterial stiffness. PWV was an important determinant of LVMI and LVVI in CKD patients.
