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.
