Popis: Background: Cardiovascular disease is the leading cause of mortality amongst patients with chronic kidney disease (CKD). This is the first study using 3-dimensional echocardiography (3DE) to investigate associations between adverse changes of the left ventricle, and different stages of CKD. Methods: Participants were recruited from the Copenhagen CKD cohort study and the Herlev-Gentofte CKD cohort study. Patients were stratified according to GFR category (G1+2: eGFR≥60mL/min/1.73m 2 , G3: eGFR = 30-59mL/min/1.73m 2 , and G4+5: eGFR≤29mL/min/1.73m 2 ), and according to albuminuria (A1: UACR300 mg/g). Echocardiograms were analysed for left ventricular (LV) mass index (LVMi), LV ejection fraction (LVEF), and global strain measures. In adjusted analysis, eGFR groups were adjusted for confounders and albuminuria category, while albuminuria groups were adjusted for confounders and GFR category. Results: The study population consisted of 662 outpatients with CKD and 169 controls. Mean age was 57±13 years, and 61% were males. Mean LVEF and global longitudinal strain (GLS) were increasingly impaired across eGFR groups: LVEF = 60.1%, 58.4%, and 57.8% ( p =0.013), GLS = -16.1%, -14.8%, and -14.6% ( p 2 , 88.1g/m 2 , and 92.1g/m 2 ( p =0.007) from A1-3. Adjusted analysis confirmed reduced LVEF in G3 compared with G1+2, and increased LVMi in A3 compared with A1. Conclusion: Increasingly impaired eGFR was associated with adverse changes in LV systolic function, while albuminuria was associated with adverse changes in LV mass assessed by 3DE. Their associations were independent of each other.
