Does an updated clinical prediction rule improve the estimation of coronary artery disease probability compared to the original Diamond-Forrester model?
An updated clinical prediction rule improves upon the Diamond-Forrester model for diagnosing CAD, particularly by addressing overestimation in women and extending applicability to older patients.
Our results suggest that the Diamond-Forrester model overestimates the probability of CAD especially in women. We updated the predictive effects of age, sex, type of chest pain, and hospital setting which improved model performance and we extended it to include patients of 70 years and older.
