Cardiovascular Disease

I became a little more interested in the heart and wondered a little about heart disease.  I found some interesting information.  61 millions americans are faced with cardiovascular disease.  There are different types including, high blood pressure, hardening of the arteries, heart attacks, and stroke.  The heart is obviously the center of the cardiovascular system and pumps blood to all of the cells in our body.  It also carries oxygen, which the cells need. When these things aren't happening we are faced with problems, know as cardiovascular disease.  


Some problems that go along with heart disease are:


Arteriosclerosis: also called hardening of the arteries, arteriosclerosis means the arteries become thickened and are no longer as flexible.
Atherosclerosis: a buildup of cholesterol and fat that makes the arteries narrower so less blood can flow through. Those buildups are called plaque.
Angina : people with angina feel a pain in the chest that means the heart isn't getting enough blood.
Heart attack: when a blood clot or other blockage cuts blood flow to a part of the heart.
Stroke: when part of the brain doesn't get enough blood due to a clot or a burst blood vessel.


Below is a video of an actual surgery, While the heart is still beating. VERY INTERESTING:
