Are fasting lipid levels more predictive of cardiovascular outcomes than nonfasting lipid levels?
A Scandinavian cohort study of more than 8,000 primary prevention patients supports current guidelines that recommend checking lipid levels in nonfasting patients. In this study, patients were administered both fasting and nonfasting lipid testing. Although triglyceride levels were higher in nonfasting patients, cholesterol levels were similar whether the patient was fasting or not. In addition to being easier to obtain, nonfasting lipids were equally predictive of subsequent cardiac events.
