Options

A. a condition in which heart stop beating.
B. When the heart muscle is suddenly damaged by an adequate blood supply .
C. Congestion of the lungs is one of the main symptoms of this disease.
D. Chest pain appears when no enough oxygen is reaching to the heart muscles

Answer

To solve the question regarding which statement is correct about heart failure, let's analyze each statement step by step.

### Step-by-Step Solution:

1. **Understanding Heart Failure**:
- Heart failure is a condition where the heart is unable to pump blood effectively to meet the body's needs. It does not mean that the heart has stopped beating; rather, it is not functioning properly.

**Hint**: Remember that heart failure refers to the heart's pumping efficiency, not its ability to beat.

2. **Evaluating the Statements**:
- **Statement 1**: "A condition in which the heart stops beating."
- This statement is incorrect. The heart may still be beating, but it is not pumping blood effectively.

**Hint**: Differentiate between heart failure and cardiac arrest; cardiac arrest is when the heart stops beating.

- **Statement 2**: "The heart muscle is suddenly damaged by an inadequate blood supply."
- This statement describes a heart attack, not heart failure. In heart failure, the heart is not pumping blood adequately, but it does not imply sudden damage to the heart muscle.

**Hint**: Focus on the distinction between heart failure and heart attack.

- **Statement 3**: "Congestion of the lungs is one of the main symptoms of this disease."
- This statement is correct. Congestion in the lungs is indeed a common symptom of heart failure due to fluid buildup when the heart is not pumping effectively.

**Hint**: Recall that fluid buildup in the lungs is a hallmark of heart failure.

- **Statement 4**: "Chest pain appears when not enough oxygen is reaching the heart muscles."
- This statement refers to angina, which is a symptom of heart-related issues but not specifically heart failure. It is not a defining characteristic of heart failure.

**Hint**: Identify that chest pain due to lack of oxygen is more related to angina than to heart failure.

3. **Conclusion**:
- The correct statement about heart failure is the one that mentions congestion of the lungs as a symptom. Therefore, the correct answer is **Statement 3**.

### Final Answer:
The correct statement about heart failure is: "Congestion of the lungs is one of the main symptoms of this disease."
