What does C-reactive protein indicate in cardiovascular health?

C-reactive protein (CRP) is a substance produced by the liver in response to inflammation. In the context of cardiovascular health, elevated levels of CRP indicate the presence of systemic inflammation, which is a risk factor for various cardiovascular diseases such as coronary artery disease. The relationship between CRP and cardiovascular health is significant because high CRP levels can be associated with atherosclerosis, unstable plaques, and an increased risk of heart attacks and strokes.

While the other options suggest various states of health and inflammation, they do not accurately represent the role of CRP. For instance, decreased risk of heart disease or improved cardiac function related to lower CRP levels, and a normal inflammatory response suggest healthy levels of CRP. However, elevated CRP levels indicate increased inflammation, reflecting a heightened risk for cardiovascular issues. Therefore, understanding CRP as an indicator of inflammation helps in assessing cardiovascular health risks effectively.
