Heart attack

About Heart attack

Heart attack is a common cause for deaths in most adults. The risk is even more in people with age of 65 and above. While there are many reasons for a heart attack to occur, the most common causes include the inability for the heart to pump adequate level of blood or when enough blood does not reach the heart. The blood supply is usually blocked by narrowing arteries or a blood clot.

Studies show that heart attack risk increases on obesity, snoring, air pollution, certain diabetes drugs and lung disease inhalers, poor dental hygiene and bleeding gums, Bisphenol A - a chemical used in plastic bottles, Viagra, big sport games, heriditary reasions etc.

Not all heart attacks cause death. However, every heart attack is really painful. A team at the University of Southampton is studying to demystify near-death experiences, a type of cardiac arrest in which all three criteria of death are present.

Another study showed that, unlike perseived, Lipitor (in women) and Folic acid-fortified bread does not reduce heart attack risk.

The human body has a mechanism to overcome heart attack risk but external factor often over react. A study for instance, showed that Human embryonic stem cell secretions reduce heart injury by 60pc in pigs.

Numbers

Over 800,000 people die in the US each year from cardiovascular disease and strokes.
About 80% of all strokes are preventable.

Heart Attack, Cardiac Arrest and Heart Strokes

A heart attack occurs when the blood supply to the heart is severely reduced or cut off.
A Cardiac arrest occurs when the heart suddenly stops beating, preventing blood and oxygen from getting to vital organs. Automated external defibrillator is used to get the heart to get beating again.
Heart strokes occur when the blood flow to the brain is interrupted or severely limited. This results in cutting off oxygen and nutrients from brain tissue.

Reasons for heart attack
