What is a heart attack?
A heart attack (also known as a myocardial infarction) is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen,causing injury to the heart muscle. Injury to the heart muscle causes chest pain
and chest pressure sensation. If blood flow is not restored to the heart muscle within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur. Muscle continues to
die for six to eight hours at which time the heart attack usually is "complete." The dead heart muscle is eventually replaced by scar tissue.
Approximately one million Americans suffer a heart attack each year. Four hundred thousand of them die as a result of their heart attack.

My daughter is 19 years old. About six months ago, she developed severe chest pain with palpitations. She was admitted to the hospital. Her heart rate remained between 130 and 160 for four days. She had a normal echo, normal EKGs and normal lab results. She was sent home on Toprol and has continued to have a rapid heart rate in the 90s to low 100s with activity. She also continues to have chest pain. She has been told it is stress, but she says she does not feel stressed. We had a stress test done and are waiting on the results, but she says the doctor who performed the test told her she was not active enough. She is a non-smoker, non drinker, no caffenine, young woman. She had no health issues before this. Published: January 09 ::
