Does the addition of CACS to traditional risk factors improve risk classification for coronary heart disease prediction in a multi-ethnic cohort?
Adding Coronary Artery Calcium Score (CACS) to traditional risk factor models significantly improves coronary heart disease risk classification.
In this multi-ethnic cohort, addition of CACS to a prediction model based on traditional risk factors significantly improved the classification of risk and placed more individuals in the most extreme risk categories.
