A heart attack occurs in the U.S. every 40 seconds.
The more time that passes without treatment, the greater the damage to the heart muscle, according to the U.S. Centers for Disease Control and Prevention (CDC).
While coronary artery disease is the main cause of heart attack, a severe spasm or sudden contraction of a coronary artery can also stop blood flow to the heart muscle.
