Accuracy of Diamond-Forrester estimates for CAD declining, says JAMA study
USA: The accuracy of Diamond-Forrester estimates of pretest probability of coronary artery disease (CAD) are declining, according to the authors view point, published in the journal JAMA Internal Medicine.
According to the authors, the European CAD Consortium estimation method is the most reliable.
The Diamond-Forrester estimates were developed in the late 1970s based on a small group of highly selected patients, most of whom were men with an average age <50 years. Since then, the epidemiology of CAD has changed considerably. Now, the patients tend to be older and there are more women.
The consortium estimates are based on data for 2260 patients from 14 catheterization laboratories and yield better classification of women, usually downward relative to Diamond-Forrester classification.
A 2019 study that compared various risk scores found that the CAD Consortium clinical score performed best among the 3 options (updated Diamond-Forrester, CONFIRM risk score, consortium score), although not perfectly.
