ANCHOR LEAD: CAN TRIGLYCERIDE LEVELS SIGNAL HEART DISEASE RISK? ELIZABETH TRACEY REPORTS
Most people have had the experience of having to wait to eat anything until after having blood drawn for certain tests. Now triglyceride levels, which are one indicator of heart disease risk, may be able to be drawn anytime, based on a study showing that non-fasting levels are more predictive. Rick Lange, chief of clinical cardiology at Johns Hopkins, explains why.
LANGE: When we eat a diet that is high in fats, that fat is absorbed from the intestine into the bloodstream, and initially it’s metabolized to form a particular lipoprotein that’s called a remnant particle. And that remnant particle is high in triglycerides and cholesterol and it can get into the arterial wall just like LDL cholesterol. So people that have high triglycerides have high remnant particles soon after they eat, and those can get into the blood vessel just like LDL cholesterol can, and clog the blood vessel. :28
Other blood tests may still require a fasting state, however. I’m Elizabeth Tracey reporting.
