Gamblers,
weathermen, and Dionne Warwick aren't the only people who try to make a living
predicting the future. Doctors do, too. Just as a gambler might gather stats
like Sammy Sosa's slugging percentage on Thursday games at home when the wind
is less than 15 mph, a doctor gathers vital information to try to determine the
odds on your health.
For
years, physicians focused on basic measures, such as blood pressure, weight,
and cholesterol. But recently, more and more studies have shown that there's a
new MVP (most valuable predictor) when it comes to forecasting heart disease.
It's a substance that sounds like a grunge-rock band: C-reactive protein (CRP).
Though
it was discovered in 1930, only in the past several years has CRP been shown to
be important. Doctors now know that CRP helps measure chronic inflammation and
the overall health of your arteries. The higher your CRP level, the more at
risk you may be for heart disease—even if your other indicators look normal.
"Half
of all heart attacks and strokes in the United States each year occur among
people with essentially normal cholesterol levels," says Paul Ridker,
M.D., a professor of medicine at Harvard medical school. "There's more to
heart disease than just lipids. In addition to the problem of cholesterol,
there's the problem of the immune system or the inflammation response."
A
heart attack occurs when plaque ruptures inside your blood vessels. But that
rupturing hinges not just on how much plaque you have but also on the degree of
inflammation, Dr. Ridker says. Your level of CRP—measured by a simple blood
test—helps detect this condition so you can predict whether you're in danger of
cardiovascular disease and stroke. "You can be at quite a high risk of
both despite having normal cholesterol," Dr. Ridker says. "Even
people with low cholesterol but high CRP are at high risk."
Luckily,
just as you can with cholesterol and body fat, you can take steps to shrink
your CRP. "If you have your CRP measured in your 20s and 30s, you can
prevent heart disease and strokes in your 50s and 60s," Dr. Ridker says.
Aside from drugs such as statins, lifestyle changes are the best way to whittle
down your CRP and, more important, snuff the flames before they snuff you.
