Blocked Arteries Are Not Found In Most Heart Attack Victims

A research paper showed that patients suffering an acute heart attack, 49% had a blockage, 30% had no blockage, 14% had insufficient blockage to cause heart muscle damage, and 7% had another condition altogether.  Another paper showed that the longer the time between the heart attack and death, the greater the blockage.  If death occurred one hour or less after a heart attack, only 16% had sufficient blockage to cause the heart attack. The increase in blockage as time passed before autopsy led the authors to believe that the blockages did not cause the heart attacks, but rather then blockages were caused by the heart attacks, and increasingly built up in the hours before death.
