Narrowing of lumen of atery due of deposition of fats is called

Options

A. Angina pectoris
B. Cardiac arrest
C. Heart failure
D. Atherosclerosis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the narrowing of the lumen of an artery due to the deposition of fats.

2. **Identifying the Process**: The process of fat deposition in the arteries is a significant health concern. It primarily involves the accumulation of fatty substances, particularly cholesterol and triglycerides.

3. **Recognizing the Condition**: This condition is known as **atherosclerosis**. Atherosclerosis is characterized by the buildup of plaques in the arterial walls, which leads to the narrowing of the lumen.

4. **Understanding the Implications**: The narrowing of the artery can reduce blood flow, and in severe cases, it can lead to complete blockage. This can result in various cardiovascular issues, including coronary artery disease (CAD).

5. **Differentiating from Other Conditions**: It is important to note that atherosclerosis is distinct from other heart conditions like angina pectoris (chest pain due to reduced oxygen supply) and cardiac arrest (heart's failure to pump blood).

6. **Final Answer**: Therefore, the correct answer to the question is **atherosclerosis**.
