A clogged artery occurs when a buildup of cholesterol and other substances narrows or blocks one or more of your arteries. The most common symptom of clogged arteries is chest pain or discomfort (angina). Clogged arteries can also cause shortness of breath, fatigue, and pain in your legs, neck, jaw, back, or arms.
Clogged arteries are a serious condition that can lead to a heart attack or stroke. If you have any of the symptoms of clogged arteries, it’s important to see your doctor right away.
