Assertion (A): Coronary artery disease is primarily caused by a buildup of calcium, fat, cholesterol, and fibrous tissues in the arteries.
Reason (R): This accumulation leads to the narrowing of the arterial lumen, which reduces blood flow to the heart muscle.
  • a)
    If both Assertion and Reason are true and Reason is the correct explanation of Assertion
  • b)
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  • c)

Understanding Coronary Artery Disease (CAD)
Coronary artery disease (CAD) is a significant health concern, and both the assertion and reason provided are fundamentally accurate.
Assertion Analysis
- CAD primarily stems from a buildup of:
- Calcium
- Fat
- Cholesterol
- Fibrous tissues
This accumulation, often referred to as atherosclerosis, leads to the formation of plaques in the coronary arteries.
Reason Analysis
- The buildup results in:
- Narrowing of the arterial lumen
- Reduced blood flow to the heart muscle
This reduction in blood flow can lead to serious complications, such as angina, heart attacks, or heart failure.
Connection Between Assertion and Reason
- The reason explains the assertion effectively:
- The accumulation of substances in the arteries directly contributes to narrowing.
- This narrowing is the mechanism through which CAD affects blood flow to the heart.
Therefore, the reason provided not only supports the assertion but also clarifies how the process occurs.
Conclusion
- In conclusion, both the assertion and reason are true, and the reason correctly explains the assertion. Hence, the correct answer is option 'A'. Understanding this relationship is crucial for grasping the pathophysiology of coronary artery disease and its impact on cardiovascular health.

  • Assertion Analysis: The assertion is true as coronary artery disease (CAD) is indeed caused by the buildup of substances such as calcium, fat, and cholesterol in the arterial walls.
  • Reason Analysis: The reason is also true because the described accumulation does lead to the narrowing of the arteries, which is a key characteristic of CAD.
  • Explanation Relation: The reason directly explains the assertion as it describes the process through which CAD occurs. Thus, both the assertion and reason are true, and the reason accurately explains the assertion.
 
Topic in NCERT: Coronary Artery Disease (CAD)
Line in NCERT: "Coronary Artery Disease, often referred to as atherosclerosis, affects the vessels that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower."
