Coronary artery disease (CAD) develops when fatty deposits called plaque build up in the two major arteries that wrap around the outside of your heart and supply it with oxygen-rich blood. Plaque makes the arteries hard and narrow so it’s hard for blood to flow through them. This can cause angina (chest pain), shortness of breath and even a heart attack.
You’re more likely to develop coronary artery disease if you’re overweight, smoke, or have high blood pressure or high cholesterol. Your risk also increases if you have a family history of coronary artery disease.
