Abstract:
Purpose To explore the changes in biventricular volume and mass in chronic kidney disease(CKD)patients with preserved ejection fraction using cardiac magnetic resonance(CMR),and evaluate cardiac function using tissue-tracking strain analysis.Materials and Methods The retrospective analysis of 40 CKD patients without symptoms of cardiovascular disease,diabetes and the estimated glomerular filtration rate<60 ml/(min·1.73 m2)who were treated at the First Affiliated Hospital of Anhui Medical University from October 2020 to June 2023 and 25 age-and gender-matched healthy volunteers.All participants underwent 1.5T CMR scans to calculate left and right ventricular function,myocardial strain and native T1 and T2 values,and differences in various imaging parameters between the two groups were compared.Results The native T1 value[(1 109.6±35.9)ms]and T2 value[(58.1±2.9)ms]of CKD patients were significantly higher than those in control group[(1 046.3±15.9)ms,(53.3±2.3)ms](t=8.296,6.916,both P<0.001).The left ventricular end-diastolic volume index,left ventricular end-systolic volume index,left ventricular mass index,right ventricular end-diastolic volume index,right ventricular end-systolic volume index and right ventricular mass index of CKD patients were significantly increased compared with the control group(t=3.233,3.350,5.751,7.746,5.937,2.363,all P<0.05),while the left and right ventricular strain parameters,left ventricular global longitudinal strain,left ventricular global circumferential strain,left ventricular global radial strain,right ventricular global longitudinal strain,right ventricular global circumferential strain and right ventricular global radial strain were significantly decreased(t=9.506,9.072,-10.603,10.496,11.574,-4.018,all P<0.001),and the estimated glomerular filtration rate exhibited significant correlations with left ventricular global longitudinal strain(r=-0.636),left ventricular global radial strain(r=0.688),right ventricular global longitudinal strain(r=-0.513),right ventricular global circumferential strain(r=-0.827)and right ventricular global radial strain(r=0.514)(all P<0.001).Conclusion CMR can quantitatively assess myocardial fibrosis and edema in patients with CKD,and tissue tracking strain analysis can detect myocardial motion abnormalities before changes in ventricular ejection fraction,offering value in the early detection of cardiac involvement in CKD patients..
