Abstract

Liver fibroscan has recently been suggested as an alternative method to measure liver steatosis noninvasively. In this study, we evaluated usefulness of controlled attenuation parameter (CAP) for detecting increased arterial stiffness in general population. A total of 515 asymptomatic patients without potential cause of liver disease who had liver fibroscan and cardio-ankle vascular index (CAVI) during their health check-up exams were included. A cut off of CAP ≥222 dB/m was used to define fatty liver and CAVI ≥ 8 for increased arterial stiffness. Both unadjusted and adjusted regression analyses showed significant association between fatty liver and increased arterial stiffness [unadjusted Odds ratio (OR) 1.896, 95% CI 1.305-2.754, p = .001 for CAP ≥ 222 dB/m alone]. With all traditional cardiovascular risk factors such as age, gender, body mass index, hypertension, diabetes mellitus, hypercholesterolemia and smoking adjusted, CAP ≥ 222 dB/m still showed significant association with increased arterial stiffness (OR 2.309, 95% CI 1.419-3.756, p = .001). The correlation between CAP-defined fatty liver and arterial stiffness was especially strong in subjects without diabetes (OR 2.959, 95% CI 1.709-5.122, p < 0.001). CAP ≥ 222 dB/...Continue Reading
