CHD cholesterol refers to cholesterol that contributes to Coronary Heart Disease (CHD), a condition where plaque builds up inside the coronary arteries. This buildup, often caused by cholesterol, can narrow or block these arteries, restricting blood flow to the heart.
Understanding the Role of Cholesterol in CHD
Cholesterol, a waxy substance, is crucial for many bodily functions. However, when there is too much cholesterol in the blood, it can accumulate in the artery walls, forming plaque.
How Cholesterol Leads to Plaque Buildup
- Formation of Plaque: Cholesterol, along with other substances, deposits in the lining of arteries, creating plaque. This plaque can make the artery walls hard and narrow.
- Blood Flow Restriction: As the plaque grows, it restricts the space for blood to flow. This can reduce the amount of oxygen and nutrients reaching the heart muscle.
- Risk of Heart Problems: Restricted blood flow can cause chest pain (angina) or lead to a heart attack if an artery becomes completely blocked.
Impact of Plaque in Coronary Arteries
The reference states that coronary artery disease is often caused by cholesterol, which builds up inside the lining of the coronary arteries, forming plaque. This plaque can partially or totally block blood flow in the large arteries of the heart.
Here's a table summarizing the impact:
| Consequence | Description |
|---|---|
| Plaque Buildup | Accumulation of cholesterol and other substances in artery walls. |
| Artery Narrowing | Plaque reduces the diameter of arteries. |
| Reduced Blood Flow | Less blood, and therefore oxygen, reaches the heart muscle. |
| Potential Heart Problems | Increased risk of angina, heart attacks, and other cardiac events. |
Key Takeaway
The cholesterol associated with CHD is the same cholesterol found in the blood, but it is specifically the excess that contributes to the plaque formation in the coronary arteries. This plaque formation is a key factor in the development of coronary heart disease.
