A heart attack occurs when the flow of blood to the heart is blocked .The blockage is most often a build up of fat ,cholestrol and other substances ,which form a plaque in the arteries that feed the heart (coronary arteries)
The plaque eventually breaks away and forms a clot .The interrupted blood flow can damage or destroy part of the heart muscle
A heart attack also called a myocardial infarction ,can be fatal but treatment has improved dramatically over the years .It's crucial to call 911 or emergency medical help if you think you might be having a heart attack .

Some heart attacks strike suddenly ,but many people have warning signs and symptoms hours ,days or week in advance
