Options

A. Heart attack
B. Angina
C. Cardiac arrest
D. Coronary artery disease

Answer

To solve the question regarding the symptom of acute chest pain when enough oxygen is not reaching the heart muscle, we can follow these steps:

### Step 1: Understand the Question
The question asks for a specific term that describes acute chest pain due to insufficient oxygen reaching the heart muscle.

### Step 2: Analyze the Options
The options provided are:
- Heart attack
- Angina
- Cardiac arrest
- Coronary artery disease

### Step 3: Define Each Option
1. **Heart Attack**: This occurs when blood flow to the heart muscle is blocked, usually by a blood clot. It is a serious condition but is not specifically described as acute chest pain due to lack of oxygen.

2. **Angina**: Also known as angina pectoris, this is characterized by temporary chest pain or discomfort due to decreased blood flow (and thus oxygen) to the heart muscle. It is often triggered by physical exertion or stress.

3. **Cardiac Arrest**: This is a sudden loss of heart function, leading to the heart stopping abruptly. It is an emergency situation but does not specifically refer to chest pain.

4. **Coronary Artery Disease**: This condition involves the narrowing or blockage of coronary arteries due to plaque buildup, which can lead to various heart issues, including angina and heart attacks.

### Step 4: Identify the Correct Answer
Given the definitions, angina is the term that specifically describes the acute chest pain resulting from insufficient oxygen reaching the heart muscle.

### Conclusion
The correct answer to the question is **Angina**.
