Inflammation and Cardiovascular Disease

Atherosclerosis is fundamentally an inflammatory disease. When LDL particles penetrate the arterial wall, they trigger an immune response. Macrophages engulf oxidized LDL, becoming foam cells that form the core of atherosclerotic plaques. This ongoing inflammation destabilizes plaques, making them prone to rupture. CRP is produced by the liver in response to inflammatory cytokines like IL-6. Elevated hs-CRP reflects this vascular inflammation, identifying patients whose plaques are actively inflamed and at higher risk of rupture, even when cholesterol levels appear normal.

1

Independent Risk Factor

hs-CRP predicts cardiovascular events independently of cholesterol levels. People with low LDL but high hs-CRP still face elevated risk.

2

Responds to Lifestyle

Unlike Lp(a), hs-CRP is highly modifiable through diet, exercise, weight loss, and stress reduction.

Optimal hs-CRP Benchmarks

Functional Range (Cardiovascular Focused) Optimal: < 1.0 mg/L
Standard Lab Range Standard: < 3.0 mg/L (low risk < 1.0, moderate 1.0-3.0, high > 3.0)

Common Questions

What causes elevated hs-CRP?

Common causes include obesity, smoking, poor diet, chronic stress, lack of exercise, gum disease, chronic infections, and autoimmune conditions. Acute illness or injury can also transiently spike hs-CRP.

How is hs-CRP different from regular CRP?

hs-CRP uses a more sensitive assay that can detect very low levels of inflammation relevant to cardiovascular risk. Regular CRP is used for detecting acute inflammation from infections or injuries.
