Which of the following causes Myocardial Infarction (MI)?
Show Hint
- Obstruction in one of the arteries supplying blood to the heart
- Obstruction in one of the arteries supplying blood to the brain
- Obstruction in one of the veins draining blood from the heart
- Obstruction in one of the veins draining blood from the brain
The Correct Option is A
Solution and Explanation
- Option (A): The correct answer. MI is caused by blockage in the coronary arteries.
- Option (B): Blockage in arteries supplying blood to the brain causes strokes, not MI.
- Option (C): Obstruction in veins would affect blood return but would not cause MI. MI is related to oxygen supply, which is primarily through arteries.
- Option (D): Similar to option (C), blockage in veins affects drainage but not oxygen supply to the heart.
Thus, the correct answer is (A) Obstruction in one of the arteries supplying blood to the heart.
Final Answer: (A)
