Answer

To solve the question "Which of the following diseases is also known as atherosclerosis?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Atherosclerosis**: Atherosclerosis is a condition characterized by the buildup of cholesterol and other substances in the walls of arteries, leading to narrowing and hardening of these blood vessels. This can restrict blood flow and lead to various cardiovascular diseases.

2. **Analyzing the Options**:
- **Option 1: Hypertension**: This refers to high blood pressure and is not synonymous with atherosclerosis. It is a separate condition that can result from atherosclerosis but is not the same.
- **Option 2: Angina Pectoris**: This is a type of chest pain caused by reduced blood flow to the heart muscle. While it can be a symptom of atherosclerosis, it is not another name for it.
- **Option 3: Heart Attack**: Also known as myocardial infarction, this occurs when blood flow to the heart is blocked, often due to atherosclerosis. However, it is not the same as atherosclerosis itself.
- **Option 4: Coronary Artery Disease**: This is a condition that results from the narrowing of the coronary arteries due to atherosclerosis. It is often referred to as atherosclerosis because the underlying cause of coronary artery disease is the buildup of plaques in the arteries.

3. **Conclusion**: Based on the analysis, the correct answer is **Coronary Artery Disease**, as it is also known as atherosclerosis.

### Final Answer:
**Coronary Artery Disease**
