C-reactive protein and inflammation
Another chemical that has been associated with an increased risk of cardiovascular diease is C-reactive protein.
High C-reactive protein (CRP) is associated with increased coronary heart disease risk even in the absence of traditional cardiac 'risk factors'.
Many studies have demonstrated a strong link between levels of CRP and 10-year risk of a heart attack. Raised CRP means a higher risk.
Indeed, a study of 27,939 apparently healthy American women followed for eight years showed that C-reactive protein level was a much stronger predictor of cardiovascular events than LDL.
But CRP is not a cause of coronary disease; it is a marker for inflammation and systemic infection.
