Quoted message said:Quoted message said:You should tell your cardiologist. It is likely he will want to
check your hsCRP level to check the reality of the decreased serum
cholesterol.
I thought you once told me checking CRP in a bypass patient wasn't
of any real significance. Is hsCRP a different test than CRP?
Mel
Yes, hsCRP is different.
Checking hsCRP is worthwhile primarily if you believe it may change
what you are currently doing.
A high hsCRP would not be a good thing for a bypass patient.
I have to wonder at the real worth of hsCRP levels as a diagnostic or
prognostic tool. If a person regularly walks or jogs it'll rise,
It shouldn't from regular exercise. Actually, it should decrease.
Quoted message said:the
test itself is highly variable for the same person in a short time span,
and someone like me would never even *get* the test based upon blood
lipid profile. The blood lipid profile is heavily weighted, yet half of
those suffering a CV event have cholesterol levels within the
recommended parameters.
Yes, if the lipid profile is checked soon after the CV event, it will
tend to be lower than the baseline *before* the event. It is the
higher baseline that is associated with increased CV risk.
Quoted message said:I regularly walk for miles almost every day, my
hsCRP may well be elevated, but with a TC of 160, LDL of 81, an HDL of
65 and tris at 62 it's not going to be checked.
If you have a CV event despite the favorable lipid profile, your hsCRP
should be checked, imo. If high in this setting, your doctor should be
aggressively addressing the reason(s) for the elevation.
Quoted message said:BTW, that's a marked
improvement from 4.5 years ago, when TC was 154 and HDL was 34 and tris
were over 200 - or is it?
It is provided hsCRP is low.
Quoted message said:That's my beef with this test, and blood
lipid tests as well. Even the test results are not much more than a
pinhole in the wall between us and our understanding of the root causes
of CVD.
One can see alot through a pinhole. Simply ask you local peeping tom
:-)
Quoted message said:Blood lipid levels aren't much of a crystal ball for the patient's
future.
It is a pretty good pinhole. See the Framingham Heart Study.
Quoted message said:Too high levels are associated with CVD. Too low levels are
associated with anemia, depression and blood vessel blowouts.
Here the clinical findings for overall poor health (emaciation,
cachexia, chronic illnesses) is more telling than the lipid profile.
Quoted message said:Where
does the real value lie in these tests for the diagnosticians and the
people they serve?
Take care,
Carmen
They are useful when applied with some thought.
