What is coronary artery disease (CAD)?

ANSWER

Coronary artery disease (CAD) happens so often you probably know someone who has it. It’s the most common type of heart disease. Although it’s the top cause of death in the U.S., there is a lot you can do to prevent or treat it.

The trouble starts when a waxy substance called plaque builds up inside the arteries that supply blood to the heart muscle. It can take decades to block the blood flow, but it can eventually cause a heart attack or failure.
