Angina pectoris is a medical condition that
literally means a choked chest. The
victim feels acute pain in his chest for a few seconds, and then it goes
away. This occurs when myocardium cells,
the muscle portion of your heart, are temporarily denied oxygen. At this stage
they do not die, but maybe weakened. If
left untreated and the disease continues, a serious condition known as
myocardial infraction or commonly called a heart attack may occur. This can severely damage the heart's
functionality. Which in turn effects our
well being. We should be educated about
the risks that go along with our cardiovascular system.
The most common cause of the condition angina
pectoris is over consumption of cholesterol.
This chemical is only needed in minute amounts, but is often eaten in
every meal. In the body, cholesterol is
responsible for the stability of plasma membranes of cells, and hormones are
produced from it. If consumed at higher
rate then needed it is stored in the tunica interna, the innermost layer, of
blood vessels. As it is stored it starts
to build up eventually clogging the vessel.
As a result of this all cells feed by the vessel die because of a lack
of oxygen. If this condition is found
early, it can be corrected with surgical procedures or, in some minor cases,
corrective procedures.
Surgical
procedures include bypass, laser and balloon surgery. In bypass surgery a vein is removed from the
lower leg and a clogged vessel is worked around. Often in type of surgery the whole mid
section of the body is cut and the ribs are pulled back, very painful with a
very slow recovery. Some hospitals have
now implemented a new technique where only a small hole is made and everything
is done via a view screen. In balloon surgery
a balloon is inserted into the vessel with the clog and is inflated. When this occurs the vessel is damaged, this
causes the cells to repair the damage and clear the clog. This is not as successful as other surgery
techniques and is often done several times before a positive result is
seen. Laser surgery is the most recent
development. Here they use a laser to
actually scrape the build up from the vessel.
This surgery is one of the most expensive surgeries available today.
Corrective
procedures include changes in lifestyle.
These can include food intake, exercise, and stress-related issues. Food intake is largely the answer to
correcting this situation. As shown
above excessive intake of cholesterol can increase the risk of a heart
attack. Coupled with excessive salt
intake can produce another problem known as hypertension or commonly called
high blood pressure. This can further
increase the risk of a heart attack since the heart has to work harder to achieve
a homeostatic state. Therefore the heart
is working with less efficiency. For
example a runner's heart may beat 64 times a minute. A person with hypertension heart rate may be
98. The runner's heart is working with
more efficiency; therefore it does not need to beat as fast as the person with
hypertension. The person with
hypertension has a high heart rate since it cannot pump as much blood per
contraction. Exercise is another
corrective procedure prescribed since it increases cardiovascular fitness. As seen above, cardiovascular fitness can
reduce the risk of heart attacks.
Stress-related issues can increase blood pressure for unknown reasons
and therefore can also increase the risk of a heart attack.
All these factors
can influence the health of our cardiovascular system therefore care must be
taken to ensure proper function. This
includes handling stress with care, eating, and exercising right.
