Another risk factor for clogged arteries is having a high blood pressure. When you have high blood pressure, there is a greater chance in speeding up the process of arterial plaque buildup. This also expedites the hardening of the clogged arteries.
Your heart is a muscle that pumps blood throughout your body, but it also needs its own blood supply. The blood vessels that provide oxygen-rich blood to your heart are called the coronary arteries. These arteries can become narrowed through build-up of plaque, which is made up of cholesterol and other substances. Narrowed arteries can cause symptoms, such as chest pain (angina), shortness of breath, and fatigue. If a plaque ruptures, a blood clot can form at the site of the rupture and block blood flow through the artery. This is a heart attack.
