Warning Signs and Prevention to Heart Attack (Part 1)
A heart attack (also called myocardial infarction) is when part of the heart muscle is damaged or dies because he is not receiving oxygen. The arteries (blood vessels) carry oxygen to the heart.
Most heart attacks are caused by a blockage in these arteries. Usually the blockage is caused by atherosclerosis, which is the accumulation of fatty deposits (called plaque) inside the artery.This buildup is like the gunk that builds up inside a drainpipe and slows the flow of water.
Heart attacks can also be caused by a blood clot that gets stuck in a narrow part of an artery to the heart. Are more likely to form clots at sites where atherosclerosis has made an artery more narrow.
How do I know if I’m having a heart attack?
The pain of a heart attack can feel like heartburn. It is also likely that you are having a heart attack if:
* Feel a pressure or crushing pain in your chest, sometimes accompanied by sweating, nausea or vomiting.
* Feel pain that extends from your chest into the jaw, left arm or left shoulder.
* Has a feeling of tightness in the chest
* Has a shortness of breath for more than a couple of seconds.
