A new study has shown that a drug, originally used to treat
juvenile rheumatoid arthritis and other rare disorders, reduces the risk of
heart attacks and strokes in people with cardiovascular disease. The drug
treatment does have a couple of drawbacks, such as the cost ($200,000 a year)
and the risk of death. In fact, in the study, deaths from infection appeared to
match any lives saved by the drug, so there was no difference in mortality. (The
medicine suppresses part of the immune system, hence the deaths caused by
infections.)
The drug, called Ilaris, reduces inflammation by inhibiting
interleukin-1β, a
substance that triggers inflammation in response to infection. The study report
hints at the fact that lowering cholesterol may not be the answer to reducing
heart attacks (half the people who have heart attacks have normal cholesterol).
People with heart disease have high levels of inflammation, which is measured
by the level of C-reactive protein in your blood. The importance of the study
is that it’s the first real evidence that if you inhibit inflammation you
reduce the risk of heart attacks.
Let me just say this: in my book, Fat: It’s Not What You Think, I say “Because atherosclerosis begins
as a lesion and inflammation, the presence of C-reactive protein may be a more
important indicator of heart disease than high cholesterol…C-reactive protein
is released into the bloodstream in response to inflammation and plaque buildup
in the coronary arteries.” I also quote a cardiologist who says, “Inflammation
is emerging as the alpha and omega of heart disease.” My book was published in
2008. Just sayin’…
But how to reduce inflammation without paying $200,000 a
year and suppressing your immune system? Some people swear by an anti-inflammatory
diet, but research hasn’t proven the efficacy of that method. I don’t know the
answer. Drugs such as Advil or Aspirin also don’t get the job done (they don’t
work on interleukin-1β,)
Maybe there’s nothing you can do. (On the other hand, my post next week questions the role of inflammation.)
If you haven’t read
my first posts, you don’t know that I haven’t had a checkup or had my
cholesterol checked in about 14 years. Not my thing. But it would be
interesting to get checked for C-reactive protein. I’ve considered doing it
just out of curiosity.
