C-Reactive Protein (CRP)

Accumulating scientific evidence over the past two decades indicates that C-reactive protein (CRP), a biomarker of low-grade inflammation, is a better predictor of heart disease risk than cholesterol levels. This finding highlights the growing importance of inflammation in understanding cardiovascular diseases.

What is C-Reactive Protein (CRP)?

C-reactive protein is a protein produced by the liver. Its levels in the blood increase in response to inflammation occurring anywhere in the body.

Role of Inflammation in the Body

Inflammation is the body’s natural protective response that helps tissues heal following injury, infection, or disease. However, persistent or low-grade inflammation can contribute to chronic health conditions, including cardiovascular diseases.

CRP Test and Its Significance

A CRP test measures the amount of C-reactive protein present in the blood. By assessing CRP levels, healthcare providers can determine the extent of inflammation in the body.

Elevated CRP levels indicate the presence of acute or chronic inflammation, though they do not identify the exact cause.

Conditions Associated with High CRP Levels

High CRP levels may be associated with several health conditions, including:

• Bacterial or viral infections

• Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis

• Autoimmune disorders, including lupus, rheumatoid arthritis, and vasculitis

• Respiratory conditions, such as asthma

Lifestyle and environmental factors, such as smoking and exposure to air pollution or hazardous environmental toxins, can also lead to elevated CRP levels.

Importance of CRP in Cardiovascular Risk Assessment

Recent research suggests that CRP is a strong indicator of cardiovascular risk, as chronic inflammation plays a crucial role in the development of heart disease. This has expanded the focus of cardiovascular risk assessment beyond traditional markers like cholesterol.
