What are the New Risk Markers for Coronary Heart Disease?

Traditional CHD risk factors used in the Framingham risk score (FRS) predictions include:

- age
- gender
- systolic blood pressure
- treatment of hypertension
- total and high-density lipoprotein cholesterol levels
- smoking
- diabetes

The newer CHD risk factors include:

- N-terminal fragment of prohormone B-type natriuretic peptide levels
- von Willebrand factor antigen levels
- fibrinogen levels
- chronic kidney disease
- leukocyte count
- C-reactive protein levels
- homocysteine levels
- uric acid levels
- coronary artery calcium [CAC] scores
- carotid intima–media thickness
- peripheral arterial disease
- pulse wave velocity

Adding coronary artery calcium [CAC] scores to the FRS improved the accuracy of risk predictions.

Levels of N-terminal fragment of prohormone B-type natriuretic peptide also improved risk predictions but to a lesser extent.

Improvements in predictions with other newer markers were marginal.
