Vascular Damage Markers

Primary Inflammatory Markers

C-reactive protein (CRP) has the best analyte and assay characteristics among inflammatory markers for assessing vascular damage, with established standardization, acceptable precision, and widespread commercial availability, according to the American Heart Association 1, 3
Risk stratification cutpoints are well-defined: low risk <1.0 mg/L, average risk 1.0-3.0 mg/L, and high risk >3.0 mg/L, as recommended by the American College of Cardiology 1, 2
CRP demonstrates independent predictive value for cardiovascular events in acute post-MI periods, recurrent disease, and primary prevention populations, with a strength of evidence level of A, according to the American Heart Association 4
Fibrinogen and serum amyloid A (SAA) are nonspecific acute-phase reactants that reflect low-grade chronic inflammatory disease when present in low concentrations, as reported by the American Heart Association 1, 5

von Willebrand Factor (vWF) is synthesized in endothelial cells and stored in Weibel-Palade bodies, released into circulation under various stimuli as a marker of endothelial activation, according to the International Society on Thrombosis and Haemostasis 7
The platelet count/vWF antigen ratio has demonstrated strong prognostic value in disseminated intravascular coagulation, with a hazard ratio of 2.5, as reported by the International Society on Thrombosis and Haemostasis 7
Soluble thrombomodulin represents fragments of membrane-bound thrombomodulin cleaved by leukocyte-derived proteases or metalloproteases, released into circulation during sepsis and inflammatory diseases, according to the International Society on Thrombosis and Haemostasis 7
Angiopoietin-2 is stored in Weibel-Palade bodies and released during endothelial activation, serving as a biomarker for endothelial dysfunction, with an odds ratio of 3.2 for cardiovascular events, as reported by the International Society on Thrombosis and Haemostasis 7

Circulating soluble adhesion molecules, including intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin, serve as markers of endothelial activation, according to the American Heart Association 3, 6
Interleukin-6 (IL-6) promotes CRP synthesis and demonstrates prognostic value, with elevated levels indicating increased risk of adverse outcomes, as reported by the American College of Cardiology 5, 6

For cardiovascular risk assessment, measure high-sensitivity CRP in intermediate-risk patients (10-20% 10-year CHD risk) when additional risk stratification would influence treatment decisions, as recommended by the American College of Cardiology 2
Use established CRP cutpoints for risk stratification: <1 mg/L (low), 1-3 mg/L (moderate), >3 mg/L (high cardiovascular risk), according to the American College of Cardiology 2

CRP cannot differentiate between bacterial infection, viral infection, tissue injury, chronic inflammatory conditions, or malignancy without clinical context, as reported by the American Heart Association 4
Absolute marker values must be interpreted in context of clinical scenario, baseline patient factors, and temporal trends—markers aid but cannot replace clinical assessment, according to the American College of Cardiology 4
