Show Hint
Angina vs Heart Attack:
Angina = Temporary reduced blood flow.
Heart attack = Complete blockage causing tissue death.

- metabolic disorder of pancreas
- deficiency of iodine in diet
- reduction in blood supply to cardiac muscles due to atherosclerosis
- long term exposure to dust particles as in silicosis

The Correct Option is C
Solution and Explanation
Concept: Angina pectoris is a condition characterized by chest pain due to insufficient oxygen supply to the heart muscles (myocardium). This usually occurs because of narrowing of coronary arteries.
• Atherosclerosis: Deposition of fatty plaques in arteries
• Leads to narrowing of coronary arteries
• Reduces blood flow and oxygen supply to cardiac muscles
Step 1: Understand the cause of angina.
Angina occurs when the oxygen demand of the heart exceeds the supply due to restricted blood flow.
Step 2: Analyze options.
• (A) Pancreatic disorder: Related to diabetes, not angina
• (B) Iodine deficiency: Causes goitre, not chest pain
• (C) Reduced blood supply due to atherosclerosis: Direct cause of angina
• (D) Dust exposure: Causes lung diseases like silicosis
Step 3: Conclusion.
Thus, angina pectoris is mainly caused by reduced blood supply to cardiac muscles due to atherosclerosis. Final Answer: Option (C)
