Heart disease is the leading
cause of death in Australia with around 40% of all deaths
being directly related to poor cardiovascular health. Cardiovascular
risk factors include conditions such as high cholesterol levels,
high blood pressure and type 2 diabetes.
Cholesterol
One of the most common conditions that contribute to increased
risk of heart disease is elevated cholesterol levels. While
cholesterol is a very important substance that is found in
all the cells of the body, and is needed to make hormones
and vitamin D, too much can be a bad thing. Most people are
familiar with the expressions “good” and “bad’
cholesterol. Bad cholesterol, or LDL (low density lipoproteins),
is the form of cholesterol that can build up in the arteries,
causing a narrowing of the blood vessel. Good cholesterol
or HDL (high density lipoproteins) is used to carry cholesterol
from other parts of the body back to the liver where it is
processed and removed. More good HDL cholesterol means lower
risks of heart disease.
Cholesterol testing will usually also measure triglyceride
levels. Triglycerides are the fats that are found floating
in the bloodstream.
While many people have a family history of elevated cholesterol,
many more have raised their cholesterol levels simply through
poor eating habits and lack of exercise.
High cholesterol is typically controlled with the use of
a class of medication called ‘statins’. Statin
drugs such as Lipitor, Zocor and Pravachol work by stopping
the activity of a liver enzyme responsible for the production
of cholesterol.
Hypertension
Hypertension or high blood pressure affects millions of Australians.
Essentially, the heart is beating more forcefully in an effort
to push blood around the body. This puts strain on all the
blood vessels, most especially those that lead directly from
the heart. The risk of damage is further increased if a higher
than normal cholesterol level has reduced the diameter of
these blood vessels, causing back pressure on the heart as
it pumps blood out.
Blood pressure is measured by two readings. The systolic
reading is the reading of the pressure in the heart as it
is pumping blood out of it. This is the higher reading in
a blood pressure examination and should fall within the ‘normal’
range of 110 – 130 mmol/Hg. The diastolic reading is
the lower reading, measuring the pressure in the heart ‘at
rest’ after it has pumped the blood. This reading usually
has a normal range between 70 – 80 mmol/Hg.
Blood pressure is often treated in a number of ways. Drugs
called ACE inhibitors are commonly prescribed to control blood
pressure. They work by blocking the chemicals that cause the
arteries to narrow, thus giving the heart more ‘room’
or ‘space’ to push into – which means less
resistance.
Beta blockers are another commonly prescribed blood pressure
medication. Beta blockers work by blocking the action of a
chemical called noradrenaline that can cause arteries to constrict.
Much like ACE inhibitors, Beta blockers can cause a widening
of the blood vessels which means less back pressure on the
heart.
Calcium channel blockers are drugs that limit the amount
of movement of calcium through cell walls. While different
forms of calcium channel blockers work in different parts
of the body, those prescribed for lowering blood pressure
do so by reducing the force of contraction of the heart muscle.
They also relax the blood vessel walls, again widening the
diameter of the blood vessels and allowing the blood to be
pumped into them from the heart much more easily and with
less resistance.
Integrative Medicine Treatments
Food is an important consideration in managing cardiovascular
disease. Avoiding those foods that may lead to increased cholesterol
levels is very important, as is including those foods that
can help to raise good cholesterol, and maintain healthy blood
pressure levels.
As with diabetes friendly foods, heart friendly foods tend
to be unprocessed whole foods like grains, meats ,vegetables
and fruit. Oat bran has been shown consistently to lower cholesterol
levels and oats themselves are a rich source of magnesium
that is beneficial in relaxing blood vessels. Meats choices
should ideally be lean ones. Lean poultry and fish and occasional
cuts of lean red meat are all sound.
Supplementation
Quite a few people seem afraid to supplement for improved
cardiovascular health. While conventional medical therapies
are very effective, there are many natural substances that
can make a tremendous improvement to heart health.
Policosanols
Policosanols are natural derivatives of sugar cane wax. These
substances have been clinicall shown to effectively increase
HDL levels, decrease LDL levels and decrease levels of triglycerides
as well. Policosanol works in a similar fashion to the statin
drugs, slowing the production of cholesterol in the liver.
Unlike the statin medications, there are no known side effects
of policosanol other than some occasional weight loss.
CoEnzymeQ10
CoEnzymeQ10 (CoQ10)is an extremely important cardiovascular
substance to consider when supplementing for good cardiovascular
health. It is a fat soluble antioxidant that has energy boosting
and blood pressure lowering properties. It is most important
in people who are taking statin medications for high cholesterol
levels as the enzyme system that those drugs affect is the
same that allows the body to extract CoQ10 from the food we
eat. In short, most people on statin medicines will not be
making adequate amounts of CoQ10.
If you are taking a cholesterol lowering medicine, ask yourself
this. Have you ever felt like you are constantly tired or
running low on energy? Have you ever experienced aches or
pains in the legs, hips or lower back? Both of these symptoms
are very common in people who take cholesterol lowering drugs,
mainly because they are deficient in CoQ10.
In Japan, CoQ10 has been a government subsidised heart medication
since 1974 where research consistently shows that more than
70% of heart disease patients improve after taking it.
Fish Oils
As well as their ability to reduce inflammation, fish oils
are very important supplements to consider if controlling
cholesterol is important to you. Fish oils reduce triglycerides,
the fats that float through the bloodstream, very effectively.
In fact, fish oil is so important and so beneficial for cholesterol
levels that it has been recommended by the American Heart
Association for improved heart health. If you are able to
eat plenty of fish several times a week you probably don’t
need to take a supplement. For those of us that can’t
manage to do this, fish oil capsules are cheap, convenient
and in Australia, made to the highest standards.
Nerve Tonics and Relaxers
Many many people are medicated for high blood pressure when
in fact it is their nervous systems that need the support.
The systolic blood pressure reading measures the pressure
on the heart as it is pumping blood out.
If we look at the stress response, we can see that the body
is programmed in such a way as to naturally increase blood
pressure in response to whatever it sees as a threat. This
increase in blood pressure drives more blood and nutrients
around the body, allowing that body to access more immediate
energy to run away from the danger it thinks it’s facing.
With this stress related heart pumping comes a narrowing of
the arteries – further raising the blood pressure. In
fact, there is a medical condition often referred to as “white
coat” blood pressure that describes the increase in
blood pressure seen only because the stress of a doctor taking
it causes it to shoot up.
If you have a blood pressure reading that usually features
a low bottom or diastolic reading, and a higher than desired
top or systolic level, you should really think more about
controlling your stress levels. You are more than likely experiencing
high blood pressure as a result of stress rather than because
you have anything specifically wrong with your heart.
There are dozens of extremely effective natural remedies
that will help you lower your stress levels. Talk with your
pharmacist about the best ones for your particular situation.
Quality Pharmacy is dedicated to helping our customers reduce
their cardiovascular risk as much as possible. By offering
an integrated approach to medication we feel that we can help
you stay as healthy and protected as you can possibly be.
As with any supplementation, it can be easy to become confused.
Please ask your pharmacist about the best ways you can combine
one or more of these supplements, with diet and your current
medication to ensure you are getting the most complete cardiovascular
management you can.
