Triglyceride Test and Heart Attack Profile ------------------------------------------------------------------------------ QUESTION: An article in the paper stated that now doctors think that triglycerides are more important than cholesterol in predicting your chances of getting a heart attack. Why then would a doctor still take a blood test for cholesterol? Shouldn't he be using the triglyceride test instead? Could you possibly provide me with some information on this very important subject for all to know. ------------------------------------------------------------------------------ ANSWER: Though triglycerides have taken on a new importance in evaluating the risks of heart attacks, thinking of single tests with absolute numbers is a trap we can all fall into. No single factor is an absolute predictor of future events, and no numbers are absolutes. When dealing with cholesterol and triglycerides, it is probably more useful to consider them as part of a total picture that of the fats that circulate within our bloodstream. The values found on tests for the lipoproteins can be useful tools when looked at in a global perspective. Thus the current thinking is to use cholesterol as a screening test, but to order the more complete "lipid profile" for a more realistic evaluation when the situation warrants it. A full profile includes a cholesterol, triglycerides, high density lipoproteins (HDL) and low density lipoproteins (LDL). These tests provide both the levels of each chemical in the blood stream and also permit the cross comparison of HDL with LDL also know as the HDL/LDL ratio. A physician can use these findings, along with an assessment of the patient's history and physical examination, to determine just what treatment, if any, is needed. For example, a borderline high triglyceride coupled with an acceptable LDL value may require treatment in an individual with a family history in which close family members have already had coronary heart disease. Others with the same test findings, but no family history risk factors, might not require treatment. That leaves me with a realistic but somewhat unsatisfying answer to your question, "It all depends." You should have a full, personal evaluation of your personal risk factors before tests are ordered. Then it is not the results of the tests alone that will determine your need for treatment, but the entire medical picture. And for that, I recommend a full discussion with your own physician. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
