Evaluation of cardiac remodeling in pediatric chronic kidney disease by cardiovascular magnetic resonance
Abstract
Abstract Background Children with chronic kidney disease (CKD) are at high risk of cardiovascular disease. Cardiovascular magnetic resonance (CMR) is the reference method for assessing cardiac remodeling. To our knowledge, no study has reported a comprehensive analysis of left ventricular(LV) cardiac remodeling using CMR in different stages of pediatric CKD. This prospective case-control study aimed to investigate cardiac remodeling in pediatric CKD, using CMR, and determine its relationship with risk factors. Method CMR was performed in 124 children with CKD and 50 controls. The cardiac remodeling parameters included left ventricular mass index (LVMI), LV remodeling index (LVRI), and LV wall thickness. Univariable and multivariable analyses were performed to assess the cardiac remodeling risk factors. Results Cardiac remodeling was observed in 35.5% (44/124) of children with CKD. The LVMI, LVRI, and LV wall thickness were higher in advanced stages of CKD (P < 0.05). In the CKD stage 1–2 group, a lower in the estimated glomerular filtration rate was an independent determinant of impaired LVMI (β = −0.425, P = 0.019) and LVRI (β = −0.319, P = 0.044). A higher protein to creatinine ratio(PCR) was independently associated with impaired LVRI (β = 0.429, P = 0.022). In the CKD stage 3–5 group, higher in systolic blood pressure (SBP) (β = 0.464, P = 0.005) and PCR (β = 0.852, P = 0.031) were independent determinants of impaired LVMI. Additionally, higher SBP was positively correlated with impaired LVRI(r = 0.599, P < 0.001). There was a trend toward more abnormal cardiac remodeling in the CKD stage 3–5 group with hypertension than those without. Conclusion Cardiac remodeling is prevalent in children with CKD, from an early stage. kidney markers are independently associated with cardiac remodeling. Hypertension increases the risk of cardiac remodeling in CKD stages 3–5. Strict BP control may help reverse or prevent remodeling.
