What is the Diamond-Forrester model?
The Diamond-Forrester model is a mathematical model used to predict the likelihood of a patient having obstructive coronary artery disease (CAD). The model is derived from a population of patients aged 70 years or older, and it tends to overestimate the likelihood of CAD in comparison to the prevalence observed in the Women's Ischemia Syndrome Evaluation (WISE) study. It is often used in combination with other relevant factors such as clinical evaluation and other model predictions to develop a probability estimate for an individual patient. The clinician must then use this probability estimate to engage the patient in a process of shared decision making to determine if further testing is warranted.
