A recombinant protien recommended to heart patients for dissolving blood clots in ateries is:

Options

A. TPA (Tissue plasminogen activator)
B. AAT
C. Calcitonin
D. Human growth hormone

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a recombinant protein that is recommended for heart patients to help dissolve blood clots in arteries.

2. **Identifying Options**: The options provided include:
- A) Tissue Plasminogen Activator (TPA)
- B) Alpha 1 Antitrypsin (AAT)
- C) Calcitonin
- D) Human Growth Hormone

3. **Analyzing Each Option**:
- **Option A: TPA (Tissue Plasminogen Activator)**: This protein is known for its role in breaking down blood clots. It converts plasminogen to plasmin, which helps dissolve clots. This makes it a suitable option for heart patients suffering from blood clots.
- **Option B: AAT (Alpha 1 Antitrypsin)**: This protein protects lung tissues from damage caused by neutrophils. It does not have a role in dissolving blood clots.
- **Option C: Calcitonin**: This hormone regulates calcium and phosphate levels in the blood but does not have any effect on blood clotting.
- **Option D: Human Growth Hormone**: This hormone is involved in growth and development but is not related to blood clot dissolution.

4. **Conclusion**: Based on the analysis, TPA (Tissue Plasminogen Activator) is the recombinant protein that is recommended for heart patients to dissolve blood clots in arteries.

5. **Final Answer**: The correct answer is **A) Tissue Plasminogen Activator (TPA)**.
