Serum gamma-glutamyltransferase and the burden of atherosclerosis in patients with acute coronary syndrome

GGT is an old serum enzyme that widely used as a marker of hepatobiliary disease or alcohol consumption. In patiens with raised serum GGT levels, we usually think about a problem with biliary epithelium, cholestasis, or excessive alcohol consumption. GGT itself without other inflammatory markers may not provide information to clinicans about the burden of atherosclerosis.
