Abstract

Background: The blood level of alanine aminotransferase (ALT) is associated with increased coronary heart disease (CHD) risk. However, its use as an independent factor for CHD risk prediction remains unclear in Asian populations. The purpose of this study was to examine the association between serum ALT levels and CHD risk in Koreans.

Methods: This was a cross-sectional study using data from the Korea National Health and Nutrition Examination Survey (V-1, 2010 and V-2, 2011). The ALT levels of 3,215 individuals were analyzed. The Framingham Risk Score (FRS) modified by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) was used to compute the 10-year CHD risk prediction.

Results: Positive correlations were established between log-transformed ALT concentration and FRS (r=0.433, P<0.001). After adjusting for body mass index, low-density lipoprotein cholesterol, the amount of alcohol intake, and gamma-glutamyl transferase, the odds ratio (95% confidence interval) for intermediate or greater risk of 10- year CHD prediction (10-year risk ≥10%) for the lowest quartile of participants was 2.242 (1.405-3.577) for the second quartile, 2.879 (1.772-4.679) for the third quartile, and 3.041 (1.789-5.170) for the highest quartile.

Conclusion: In Koreans, a higher serum ALT concentration was significantly correlated with 10-year CHD risk prediction according to NCEP ATP III guidelines.
