What is a heart attack??

A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. “Myo” means muscle, “cardial” refers to the heart, and “infraction” means death of tissue due to lack of blood supply.


Statistics

1.5 million heart attacks occur in the united states every year.

More than 233,000 women die annually from cardiovascular disease.

Heart Attack is a leading killer of men and women in the united states. Every 20 seconds one american suffers a heart attack



Symptoms

Some symptoms of heart attacks are:

-Discomfort, pressure, heaviness, or pain in the chest, arm, or below the breast bone.

-Discomfort radiating to the back, jaw, throat, or arm.

-Fullness, indigestion, or choking feeling (may feel like heartburn).

-Sweating, Nausea, vomiting, or dizziness.

-Extreme weakness, anxiety, or shortness of breath.

-Rapid or irregular heartbeats.


Causes

Most heart attacks are caused by a blood clot that blocks one of the coronary arteries. The coronary arteries bring blood and oxygen to the heart. If the blood flow is blocked, the heart is starved of oxygen and heart cells die.

A hard substance called plaque can build up in the walls of your coronary arteries. This plaque is made up of cholesterol and other cells.


Prevention

Stay on a healthy diet, and exercise daily!
