Dr. Bob: Working on those risk factors can definitely
improve your health. Now, let's summarize. We're talking to
Dr. George Krisle, board-certified cardiologist. We've talked
about risk factors. The first that we talked about is smoking-gotta
stop. High blood pressure-gotta get it under control. Diabetes-if
you've got diabetes, you're assumed to already have ischemic
heart disease. Get that blood sugar under control and be sure
that you're working out a program with your doctor. Now, let's
go to cholesterol. We mentioned that last. Tell me about cholesterol
and risk factors.
Dr. Krisle: Right. Hypercholesterol or cholesterol
that's too high is a critical risk factor because it can be
corrected and fixed and when it's fixed, you can live a longer
life. And remember the numbers. There're three numbers to
remember: one's the total cholesterol, and you want that under
200; the second is the LDL cholesterol, and you want that
under 100.
Dr. Bob: Now, do you call the LDL the "lousy
cholesterol?"
Dr. Krisle: Right. The LDL is the bad cholesterol.
You can remember it because L and lousy start with L and HDL
is the happy good cholesterol. You want that as high as it
can be and the recent guideline recommendations used to say
35 and now that's been changed to 40 and in reality, you want
it to be as high as it can be because it protects the heart
circulation.
Dr. Bob: How does it protect the heart?
Dr. Krisle: It's a reverse cholesterol transport and
you have to know a lot of metabolic pathways to understand
how it does this, but it's sort of like an anti-rust or protector
for keeping all the LDL, bad cholesterol, from getting plugged
up in the artery.
Dr. Bob: Now, I've heard that the HDL can actually
reverse some of the damage that's been done to blood vessels.
If they've got a lot of cholesterol deposition, it can pull
it out. Is that right?
Dr. Krisle: Right. That's called regression. If you
think of the plaque as narrowing, let's say 90% of the artery,
then if you can be a vegetarian, and an exercise guru, and
take a statin to get your cholesterol really low, the plaque
may get smaller so that the blockage is 80% or 50% or 30%.
And that's called regression. And the other thing to remember
about the statin medications in terms of cholesterol reduction
is that not only will it make your cholesterol numbers better
but there are some exciting studies that suggest it may help
stabilize the inner lining of the artery. And that's called
the endothelium and statins may make the endothelium kind
of a happy camper and so if there is any plaque there, it
may not rupture and cause a heart attack.
Dr. Bob: Now, the numbers that you mentioned, are
those the newest guidelines?
Dr. Krisle: The current guidelines are less than 200
for total, less than 100 for the LDL (lousy cholesterol),
greater than 40+ or higher for HDL. Really, really what we're
going to be looking at pretty soon is trying to get the total
cholesterol under 160.
Dr. Bob: Are most cardiologist taking statin drugs?
Dr. Krisle: That's asked in the meetings and ten years
ago you'd go to the meeting and just a few hands would go
up and now over half the hands in the room go up. So, yes,
the answer is yes, we are.
Dr. Bob: Is there some literature that shows that
if you have a normal cholesterol, normal HDL, and normal LDL
that taking statins still might help that person?
Dr. Krisle: If that person had a heart attack, you
can put forth the theory that no matter how good the numbers
look on paper, the artery is not happy with those numbers
so we need to treat the patient and not just the numbers.
So, yes, you can offer statin therapy to people who have had
a heart attack if the cholesterol is normal and you can still
make it better.
Dr. Bob: So have you found any patients that statins
didn't bring down the cholesterol?
Dr. Krisle: It always makes the numbers better. You
do have to check your liver test about every six months and
if you get any severe muscle aches, you have to report in
to your doctor right away but the balance is way toward the
good.
Dr. Bob: Next risk factor. Let's go away from cholesterol
and let's walk into sedentary lifestyle. What about somebody
that's a couch potato?
Dr. Krisle: Right. Exercise is a great, great benefit
for the heart and there is some information now when you're
out there doing your 25-30 minute walk, you're not only feeling
better because you're walking, you're helping with weight
control. But certainly the endothelium, the inner lining of
the artery, is happy with exercise. It may release something
called nitric oxide, NO, nitric oxide, and it makes the artery
smoother and happier and less likely to spasm or constrict
so there's a lot to be said for exercise, especially since
it's something we control. We can do it to ourselves.
Dr. Bob: When you use the word aerobic and anaerobic
exercise
is that what helps make this endothelial layer
happier-when you push your heart rate up? or just any kind
of exercise? or are they not sure yet?
Dr. Krisle: Traditionally, aerobic exercise has been
favored, which means in motion-walking, swimming, jogging,
bicycle riding. The old-timey, grunt and groan, 500 pound
barbell exercises are not as good for the heart.
Dr. Bob: And any type of exercise that you recommend?
Swimming, walking, bicycle riding
?
Dr. Krisle: Walking is great as long as it's done
365 days a year except leap year and then we need 366 days.
Dr. Bob: So, you're a firm believer in everyday activity
and
Dr. Krisle: Yes sir.
Dr. Bob: How long?
Dr. Krisle: 25-30 minutes minimum. If you've got 45
minutes, you can probably cover three miles and that would
be great.

minutes, you can probably cover three miles and that would

Dr. Bob: And what happens with the last risk factor
or one of the last ones, obesity. Where does that play a part?
Dr. Krisle: Right, right. Eating and obesity are very
important to your heart. If we could all be vegetarians or
close to it, and eat fresh fruits, fresh vegetables, whole
grain cereals, some fish, we'd be in great shape. It's hard
to do that. It's not how we are raised in our kind of bacon,
grits and eggs society, but if we'd eat the proper foods,
we'd be better off. If we're going to eat all other kinds
of other foods, we should at least learn to count calories
so we can keep our weight normal.
Dr. Bob: As far as risk factors go, how does the patient
get the doctor to evaluate those risk factors?
Dr. Krisle: When you go to your physician, you can
say, I am concerned about my health. I know the number one
killer of Americans is a heart attack and I want you to check
me out from head to toe and check every single risk factor
that I have and tell me where I stand and what to do.
Dr. Bob: George Krisle. Thank you very much. You're
an amazing teacher and I always love to have you on the show
because I learn to much.
Dr. Krisle: Thank you.
Dr. Bob: Are your risk factors being controlled? Do
you have risk factors? Have you seen your doctor? Have you
talked with him about those risk factors? You write them down:
cigarette smoking, high blood pressure, diabetes, cholesterol,
sedentary lifestyle, and obesity. If you've got any of those,
you have your doctor help you correct them. And now, you'll
want to stay tuned because later on we're going to be talking
about ten reasons why you are harming your health and what
we can do about that.
