"Plaques" are cholesterol deposits in the blood vessels and arteries.

The term "plaque" refers to the deposition of cholesterol and other substances on the walls of blood vessels, eventually compromising circulation. Cardiovascular disease occurs when plaque obstructs the coronary arteries that supply blood to the heart. Complete blockage of a coronary artery leads to an interruption of blood flow to the heart, or a heart attack. Blood clots also form on areas of plaque and can obstruct the arteries.

True False

Heart attack and stroke are similar events.

Both heart attack and stroke involve the interruption of blood flow to an organ due to a blockage within an artery. A heart attack results from a blocked coronary artery, while a stroke results from blockage of an artery in the brain.
