Opening all the clogged arteries with stents after a heart attack, is significantly better than opening only the blockage that caused the heart attack, according to a major clinical trial published in the New England Journal of Medicine.

Nearly half of all heart attack patients have more clogged arteries than the one that caused their heart attack. Doctors usually open only the one responsible for the heart attack,leaving the other blockages to be treated by medication alone.

Opening all blockages reduced the risk of patient’s dying or the risk of having a recurrent heart attack. The study has opened a new understanding of people suffering recurrent heart attacks.
