RESUMO
Accurate measurement of various lipids- total cholesterol, cholesterol lipoproteins and triglycerides- is important for coronary artery disease (CAD) prevention and management. Over the years many technologies have developed for their accurate measurements and in recent years the assays have been internationally standardised. Most of the guidelines recommend measurement of non fasting levels of total cholesterol, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), non-HDL cholesterol (non-HDL-C) and triglycerides (TG) for risk estimation and guiding treatment. Measurement of lipid profile in clinics and emergency departments can lead to earlier estimation of CAD risk and rapid initiation of lipid lowering therapy. CAD risk and baseline levels of LDL-C guide intensity of lipid lowering therapies. The LDL-C targets according to CAD risk are detailed in this review. There is an urgent need for standardization of lipid estimation in medical laboratories across the country so that every eligible individual can receive evidence-based lipid lowering interventions.
