Introduction

How healthy are your coronary arteries? If you eat healthy foods, get physical activity every day and don't smoke, you're well on your way to preventing symptoms of coronary artery disease — a leading type of heart disease.

The coronary arteries supply your heart with blood, oxygen and nutrients. When blood flow through the coronary arteries becomes obstructed, it's known as coronary artery disease.

Coronary artery disease is caused by the gradual buildup of fatty deposits in your coronary arteries (atherosclerosis). As the deposits slowly narrow your coronary arteries, your heart receives less blood. Eventually, diminished blood flow may cause chest pain (angina), shortness of breath or other symptoms. A complete blockage can cause a heart attack.

Since coronary artery disease often develops over decades, it can go virtually unnoticed until it produces a heart attack. But there's plenty you can do to prevent coronary artery disease. Start by committing to a healthy lifestyle.
