Importance of your Heart

You know how important your heart is, so it's no wonder people worry when they hear someone has heart problems.

Those buildups are called plaque. * Angina (say: an-jy-nuh): people with angina feel a pain in the chest that means the heart isn't getting enough blood. * Heart attack: when a blood clot or other blockage cuts blood flow to a part of the heart. * Stroke: when part of the brain doesn't get enough blood due to a clot or a burst blood vessel.
