00:01
Now, let's look at the medications
that we can use; statins.
00:04
They're the most effective and the most
common prescription that's given
to lower LDL, the bad cholesterol levels.
00:12
Okay, so I love the graphic that
we have for you here.
00:15
Atorvastatin, fluvastatin,
lovastatin, pitavastatin,
pravastatin, simvastatin.
00:22
Okay, think you kind of get the idea
on why we call them statins
because here's the other name.
00:29
Yeah, HMG-CoA reductase inhibitors.
00:33
Nobody says that. We just
call them the statins.
00:37
Now the reason they're the most
effective drugs for lowering
LDL cholesterol levels is because
they increase the number of LDL receptors
in the liver. Okay, so look at that.
00:46
See those little LDL receptors there? Look,
when we give you a statin,
your liver has more of these little
guys, these little receptors,
and they're ready to receive the LDL.
00:56
So when I have more receptors in the liver,
I have less LDL serum in the blood,
because more of it is taken
up into the liver.
01:05
That's how statins reduce
your LDL serum levels.
01:09
Okay, so the sad news is you kind
of have to take these for life,
if you can't manage your cholesterol
levels with lifestyle and diet.
01:17
Now, don't forget, lifestyle and diet
really is important. You can lower your --
you can lower your cholesterol
levels with lifestyle and diet,
but oftentimes, you need the support
of the statins to go along with it.
01:30
Either the patient has a difficult
time making those choices,
or they just are really resistant. Their
bodies are really good at LDL.
01:39
So the statins will lower LDL levels,
it will slow the progression of
atherosclerotic heart disease,
and minimize the risk of a
cardiovascular event
like heart attack or stroke.
01:50
Now, some patients will have
to take statins for life
if they can't manage their cholesterol
levels with lifestyle and diet.
01:56
And again, I want to encourage you,
don't overlook the positive benefits
of helping your patient
change their lifestyle and their diet.
02:04
They can make tremendous strides
towards lowering their LDL.
02:07
But if that isn't enough, or the patient
has a really difficult time
making those lifestyle choices,
then the statins can help.
02:14
Because they will lower the LDL
levels, and when we
can lower the LDL levels, this will slow
the progression of atherosclerotic
heart disease.
02:22
If we can slow the progression of
atherosclerotic heart disease,
then we're going to lower their
risk of cardiovascular events.
02:30
Remember, when we use that big
term, cardiovascular events,
we mean a heart attack or a stroke.
02:36
So, lower LDL
means less chance of having
a heart attack or a stroke.
02:42
We can do that with diet and lifestyle,
and also, the addition of statins.
02:48
Now, all drugs come with a price, right?
So there are some possible serious
side effects with statins.
02:55
They don't happen all the
time. They're pretty rare,
but these are the 2 things you
really want to watch for.
02:59
The first one is hepatotoxicity.
03:02
Now just take your pencil and
underline the word "toxicity."
You know what that means, right?
Toxic, no bueno. Hepat stands for liver.
03:11
So anytime you see "hepat" in something,
you know that we're referring to the liver,
like hepatitis, right?
That's inflammation of the liver.
03:20
But hepatotoxicity means
statins can be toxic to your liver.
03:25
So you want to monitor liver
function and make sure
your patient understands the importance
of us keeping an eye on that
while they're taking statins. The
other one is myopathy.
03:34
Now, that has to do with your muscle, "my."
So we want the patient to tell us if they
have any symptoms of muscle pain
or tenderness or weakness,
this might be a side effect of their statins
that they wouldn't necessarily
connect to the use of taking a statin.
03:48
So 2 rare,
but serious adverse effects of
statins, going after your liver,
hepatotoxicity, and myopathy.
03:56
So your job as a nurse is to
educate your patient,
just to make them aware that this
doesn't happen very often,
but to let us know if they notice
any of these signs.
04:06
So, the therapeutic uses for these,
if you have high cholesterol,
that's a no brainer why we'd
give a statin, right?
It increases those LDL receptors
on your liver,
takes more of the LDL out of the blood
into the liver that will lower
your LDL level.
04:22
Now, you're shooting for a target
of < 100 mg, okay?
That's what I'm shooting for,
for an LDL level.
04:30
Now, if you're a high-risk patient, that
means you have other risk factors,
like you've had a stroke, you've had
an MI, or you're diabetic,
we'd probably like you to keep it even
lower than 100, we'd like it to be lower,
like < 70.
04:43
Now, with statins
will help us reduce the risk of
cardiovascular events.
04:47
We give it to people after an
MI, post-MI because
they've had a cardiovascular event as an MI
and we don't want them to have any more,
and someone who's diabetic.
04:59
We know that our diabetic clients are at
a really increased risk for
cardiovascular events
across the board.
05:06
That's why patients will already usually
likely be put on a statin if they're diabetic
Now this one's kind of like
a unique factor of statins.
05:14
It's the timing.
05:16
Most of the manufacturers
of statins recommend
that you give these medications at night.
05:22
Okay, so I don't want to gloss over that.
05:24
This is kind of a weird thing, but
statins should be taken at night.
05:28
They've done research studies and they say
that most of the cholesterol is made when
dietary intake is the lowest.
05:34
That's why you recommend that statins,
drugs that reduce cholesterol levels,
are taken at night or at bed time.
05:42
Now, particularly, fluvastatin,
lovastatin, simavastin.
05:44
I said those kind of fast but you
know they're all statins,
they have a pretty short half-life.
But let's be honest.
05:52
When you're studying for exams,
you only have a certain amount of
real estate in your brain available.
05:57
So I just remember, across the board,
just recommend that statins
be taken at night time.
06:03
Now you'll know, if I were in your
brain, you would look up
each individual drug if you're
educating your particular patient,
but as a rule, think about statins
are given at night time
because we make most of our cholesterol
when dietary intake is the lowest.
06:16
So you want to educate your patients
to take their statin at bedtime.
