Elevated serum alanine aminotransferase (ALT) activity in the absence of viral hepatitis or excessive alcohol consumption is associated with an increased calculated 10-year risk of coronary heart disease (CHD), with the association being more prominent in women.
If your blood tests show elevated ALT levels (above 43 IU/L for men, above 30 IU/L for women) and you do not have viral hepatitis or drink heavily, this is a strong indicator of underlying metabolic issues like insulin resistance or fatty liver. These conditions significantly increase your 10-year risk of heart disease, especially for women. You should address this by focusing on metabolic health improvements, such as weight management and reducing refined carbohydrates, rather than ignoring the lab result.
In conclusion, individuals with elevated serum ALT activity in the absence of viral hepatitis or excessive alcohol consumption, most of whom have NAFLD, have an increased calculated risk of CHD. This association is more prominent in women.
Why this rating
Large, representative population-based cross-sectional study (NHANES III), though limited by lack of liver biopsy confirmation and use of calculated risk scores rather than observed events.
