Heart attacks

A heart attack is when the blood flow going to the heart suddenly becomes blocked and the
oxygenated blood can no longer reach the organ. Most heart attacks are the result of coronary
heart disease, which is caused by the buildup of fatty substances in the blood vessels around the heart.

If the blockage isn’t removed quickly, the muscle starts to die. With 1.5 million heart attacks
occurring every year in the US alone, researchers are fighting to find treatments to repair the
damage.

Currently, the surgical options to treat heart attacks are quite drastic. A coronary bypass can be done to redirect the blood away from the blocked or narrowed arteries, or a thin tube with a balloon at the end can be passed through an
artery and inflated to remove the blockage.
