Nevertheless, the relationship between cardiac remodeling, as assessed by echocardiography, and CA-AKI remains uncertain.Method: 3,241 patients undergoing coronary angiography (CAG) with/without percutaneous coronary intervention (PCI) were enrolled in this retrospective study. Collected echocardiographic parameters were normalized by body surface area (BSA) and divided according to quartile, including left ventricular internal end-diastolic diameter index (LVIDDI), left ventricular internal end-systolic diameter index (LVIDSI), and left ventricular mass index (LVMI). Logistic regression analysis was conducted to ascertain the association between structural parameter changes and CA-AKI. Further investigation was performed in different subgroups. This is a provisional file, not the final typeset articleThe mean age of all participants was 66.6 years old and 16.3% suffered from CA-AKI. LVIDSI (≥22.9mm/m 2 : OR=1.953, 95%CI [1.459 to 2.615], P <0.001), LVIDDI (≥33.2mm/m 2 : OR=1.443, 95%CI [1.087 to 1.914], P =0.011), and LVMI (≥141.0g/m 2 : OR=1.530, 95%CI [1.146 to 2.044], P =0.004) in quartile were positively associated with CA-AKI risk in the general. (all P for trend <0.05). These associations were consistent when stratified by age, left ventricular ejection fraction, estimated glomerular filtration rate, and N-terminal brain natriuretic peptide (all P for interaction >0.05). The presence of eccentric hypertrophy (OR=1.400, 95%CI [1.093 to 1.793], P =0.008) and the coexistence of hypertrophy and dilation (OR=1.397, 95%CI [1.091 to 1.789], P =0.008) carried a higher CA-AKI risk.The presence of cardiac remodeling, assessed by echocardiography, is associated with higher risk of CA-AKI.
