BACKGROUND: Cardiac remodeling has been demonstrated in patients on hemodialysis and in predialysis patients with chronic kidney disease (CKD). Using functional echocardiographic parameters to study the association of hemodynamic status and predialysis CKD has not yet been established. METHODS: From November 2007 to September 2008, ninety-six patients (50 men and 46 women) with different stages of CKD were enrolled consecutively to undergo echocardiography. Group 1 consisted of 27 patients with mild CKD (CKD stages 1 and 2) and group 2 consisted of 69 patients with moderate/severe CKD (CKD stages 3-5). RESULTS: Higher values were observed for the products of serum calcium and phosphorus, serum phosphorus, and intact parathyroid hormone; lower values were observed for hematocrit and serum albumin in group 2 patients. Higher mitral E and A velocities, longer isovolumic relaxation time, more prevalence of moderate-to-severe left ventricular (LV) diastolic dysfunction and higher mitral E/Em value were noted in group 2 patients. Eccentric left ventricular hypertrophy (LVH) had effects on systolic contraction disturbance in group 2 patients. CKD severity without LVH had effects on LV filling pressure elevation and relaxation impairment. Among biochemical and echocardiographic parameters, mitral E/Em was most independently associated with a diagnosis of moderate/severe CKD (odds ratio = 1.29, P = 0.023) and it was the most predictive variable with sensitivity and specificity values for a cutoff value of > or =13 of 64% and 74%, respectively. CONCLUSIONS: CKD severity without LVH increased LV filling pressure and impaired LV relaxation. Mitral E/Em was significantly associated with moderate/severe CKD. |
