Death of part of the muscle due to blockage of blood supply to it is called as

Options

A. Myocardial infarction
B. Myocardial ischaemia
C. Coronary thrombosis
D. Cardiac arrest

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the condition where a part of the muscle dies due to the blockage of blood supply. This is a crucial point as it focuses on muscle death specifically due to lack of blood flow.

2. **Analyzing the Options:**
- **Option 1: Myocardial Infarction**
- This term refers to a heart attack, which occurs when blood flow to a part of the heart is blocked, causing that part of the heart muscle to die. However, the question specifies "death of part of the muscle," which can be misleading as it implies a broader context than just the heart. Thus, while this option is related, it does not specifically answer the question as asked.

- **Option 2: Myocardial Ischemia**
- This refers to a condition where there is insufficient blood flow to the heart muscle, which can lead to damage and potentially muscle death if prolonged. This option aligns closely with the question as it indicates a state of reduced blood supply that can lead to muscle death.

- **Option 3: Coronary Thrombosis**
- This term describes the formation of a blood clot in the coronary arteries, which can lead to a blockage. While it can lead to myocardial infarction, it does not directly describe the death of muscle tissue itself.

- **Option 4: Cardiac Arrest**
- This condition refers to the sudden cessation of heart function, which is not directly related to the gradual death of muscle tissue due to blockage. It is more about the heart stopping rather than the death of muscle due to lack of blood supply.

3. **Conclusion:**
After analyzing all the options, the most appropriate answer to the question is **Myocardial Ischemia** (Option 2), as it directly relates to the condition of reduced blood flow leading to potential muscle death.

**Final Answer: Myocardial Ischemia**
