❤️ Thrombolytic Therapy in Myocardial Infarction (MI)

Let’s understand this in a very simple way.

What is Myocardial Infarction (MI)?
Myocardial infarction, commonly called a heart attack, occurs when a blood clot blocks a coronary artery.

👉 As a result, part of the heart muscle does not receive enough oxygen and begins to get damaged.

What is thrombolytic therapy?
“Thrombo” means clot and “lytic” means dissolve.

👉 Thrombolytic drugs are medicines that dissolve blood clots and restore blood flow to the heart.

Which drug is used as thrombolytic therapy in MI?

✅ Correct Answer: (d) Streptokinase

Why Streptokinase?
Streptokinase is a thrombolytic (clot-busting) drug that:

• Dissolves the clot in the coronary artery
• Restores blood supply to the heart muscle
• Reduces heart damage when given early

Why other options are not correct?

• (a) Heparin → ❌ Anticoagulant; prevents new clots but does not dissolve existing clots
• (b) T-PA → ❌ Also a thrombolytic drug, but many nursing exam keys traditionally expect Streptokinase
• (c) Nitroglycerin → ❌ Relieves chest pain by dilating blood vessels; does not dissolve clots

Important Nursing Point:
Both Streptokinase and Tissue Plasminogen Activator (t-PA) are thrombolytic agents. In older nursing exam MCQs, Streptokinase is often the expected answer.

Simple Exam Trick:
Heart attack + Clot dissolution → Streptokinase

📌 Disclaimer: For exam preparation only. Modern MI treatment may include PCI and various thrombolytic agents according to current guidelines.
