ObjectiveTo investigate the relationship between cardio-ankle vascular index (CAVI), which is a marker of arteriosclerosis and the development of contrast-induced nephropathy (CIN).Study DesignDescriptive study.Place And Duration Of StudyDepartment of Cardiology, Sakarya University Medical Faculty, from May to December 2019.MethodologyBetween May and December 2019, demographic characteristics, CAVI measurements, and in-hospital clinical outcomes were compared among 66 patients, who developed CIN after coronary angiography (CAG) and an acute coronary syndrome (ACS) diagnosis, and 60 ACS patients without CIN.ResultsThe frequency of CIN development in the study was 5.5%. In the CIN group, EF was lower (44.5 ± 10.6% vs. 49.3 ± 9.8%, p = 0.011) and GFR (mL/min/1.73 m2) at admission, was lower (60.3 ± 23.3 vs. 87.0 ± 21.5, p <0.001) than in the non-CIN group. CAVI values indicative of arterial stiffness (AS) were significantly higher in the CIN group. Mortality was not significantly higher in the CIN group (p = 0.099).ConclusionAS is more common in ACS patients, who developed CIN after CAG. Older patients with low EF and low GFR, in whom AS is more common, should be intravenously hydrated and more closely monitored to prevent CIN development. Key Words: Contrast-induced nephropathy, Acute coronary syndrome, Cardio-ankle vascular index, Arterial stiffness.
