Each year, more and more Americans are
diagnosed with some form of heart disease and
a lot of these cases breathe their last breath
without realizing it. Most patients with
cardiovascular complications are found to have
clogged or hardened blood vessels or what
cardiologists refer to as atherosclerosis. Many
people believe that extremely high levels of
cholesterol are at the root of this dreadful
disease and they attribute this to the excessive consumption of
fatty foods. However, there is more truth to be discovered than to
accept this popular belief. Knowing more about the real causes of
heart diseases can help a lot in lowering your chances of falling
prey to this medical condition.

For years, heart attacks have been associated with high levels of
cholesterol in the body. However, it is not merely cholesterol that
causes the problem. What really causes it is the oxidation of
cholesterol that is brought about by the presence of free radicals.
Free radicals are those highly reactive elements that can cause a
lot of damage to the cells and tissues in your body. These free
radicals can attack your blood vessels that can result to
atherosclerosis, a well known precursor to heart ailments and
cardiovascular problems.
When free radicals and oxidative stress damage the walls of your
blood vessels and cholesterol in your blood, atherosclerosis
begins. Damaged cholesterol molecules are more likely to stick to
the walls of your blood vessels and to each other, and can
eventually clog a blood vessel, resulting to a heart attack.
Another condition that precipitates heart diseases is the oxidation
of cholesterol. When cholesterol is oxidized, your body will react

by sending more and more cholesterol to the distressed area in
an effort to repair the damage. However, this can encourage the
formation of plaque deposits. As plaque deposits increase, the
blood vessel is narrowed and becomes stiffer. This will most likely
impede blood flow to and from the heart and this can trigger a
heart attack. Drugs that claim to reduce cholesterol amounts in
the body can indeed lower cholesterol present in your
bloodstream but these cannot guarantee protection from
oxidation.
Atherosclerosis and heart diseases have no preferences as to
which age group to attack. It can happen to anyone and may
start early in life. Knowing even just a couple of causes of heart
disease is important so you can do steps to avoid them. Learn
more about the causes of heart disease and join the fight in
battling this medical malady.
