Causes of Clogged Arteries. There are many substances and properties that can circulate with the blood, including cholesterol, calcium, fat, fibrin and cellular waste. When these substances accumulate on the inner walls of the arteries, they turn into plaque buildup.
Coronary arteries: When the arteries in the heart are clogged, it is called coronary heart disease, or CHD. In this case, plaque will block or narrow the coronary arteries when the heart muscle fails to get enough blood. As a result, chest pain, known as angina will occur. It feels like pressure is squeezing your chest, but you may also feel it in your jaw, neck, arms, shoulders, or back.
