ANATOMY

Detailed explanation-1: -Atherosclerosis is the buildup of fats, cholesterol and other substances in and on the artery walls. This buildup is called plaque. The plaque can cause arteries to narrow, blocking blood flow. The plaque can also burst, leading to a blood clot.

Detailed explanation-2: -High blood pressure, high cholesterol, diabetes, obesity, smoking, stress and anxiety, a sedentary lifestyle and a family history of heart disease are all key risk factors for arterial plaque buildup.

Detailed explanation-3: -Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis.
