Is cholesterol really the cause of heart disease?

Is considered bad cholesterol because it can cause plaque in your arteries?

LDL stands for low-density lipoprotein. It is sometimes called “bad” cholesterol because a high LDL level leads to the buildup of plaque in your arteries.

What is plaque and cholesterol and how does it lead to heart disease?

Plaques begin in artery walls and grow over years. The growth of cholesterol plaques slowly blocks blood flow in the arteries. Worse, a cholesterol plaque can rupture. The sudden blood clot that forms over the rupture then causes a heart attack or stroke.

What causes coronary heart disease?

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.
