What does an increase in C-reactive protein indicate?

• A. Low immunity
• B. Coronary artery disease
• C. Gastrointestinal disorders
• D. Allergic reactions

Answer: (B)

An increase in C-reactive protein (CRP) levels is indicative of inflammation in the body. Specifically, CRP is a substance produced by the liver in response to cytokines, especially interleukin-6, which is released during inflammatory processes.

In the context of coronary artery disease (CAD), elevated CRP levels signify increased systemic inflammation, which is a contributor to atherosclerosis, the buildup of plaques in the arteries. This inflammation can result in plaque instability, which is a significant risk factor for cardiovascular events such as heart attacks. Therefore, a higher level of CRP is often associated with an increased risk or presence of coronary artery disease.

While CRP can also elevate in other conditions, such as infections or autoimmune diseases, its specific association with cardiovascular health makes it a relevant marker for coronary artery disease, highlighting the importance of inflammation in cardiac conditions.
