The CAUSE OF HEART ATTACKS
is blood vessels that feed your heart being blocked
by cholesterol deposits. Cholesterol is a fatty substance.
Your heart is a muscle which pumps blood
around your body. Like the rest of the muscles of your body the heart
needs blood to nourish it. It gets this by tapping off
some of the blood it pumps to your body through some blood vessels
around itself. High blood levels of cholesterol choke
these vessels by depositing in them. A heart attack happens when your
heart can no longer get enough blood and the heart muscle suffocates to death. This is called myocardial infarction and can be seen by characteristic electrical changes on EKG.
Heart attacks are more common if:
- You are male.
- Smoke.
- Are overweight.
- Have high
blood pressure.
- Have high
blood cholesterol.
- Your close
relatives have suffered heart attacks.
