Triglycerides

Clinical Indications

High serum triglyceride concentrations may be an independent (of cholesterol) risk factor for coronary heart disease. Very high levels (>10 mmol/L) confer an increased risk of pancreatitis.
Triglycerides circulate in blood as components of various lipoproteins, particularly very light density lipoproteins (VLDL) and chylomicrons.
If drug treatment is considered appropriate in hypercholesterolaemia, the choice of drug may be influenced by the additional presence of high triglyceride levels.
