The traditional method of measuring triglyceride levels on an empty stomach could give way to a new test that appears to be a more accurate predictor of heart disease. Non-fasting triglyceride levels may have the power to predict future coronary events. Triglycerides are the chemical forms in which fat exists in the body. If fats are not immediately used by the body after eating, they are turned into triglycerides and transported to fat cells for storage. Like cholesterol, elevated triglyceride levels are linked with coronary artery disease.
