Comparison of the CAD consortium and updated Diamond-Forrester scores for predicting obstructive coronary artery disease.

Objective: Current guidelines recommend the use of the updated Diamond-Forrester (DF) method and Coronary Artery Disease (CAD) Consortium models to assess the pretest probability of obstructive CAD. The present study aimed to compare the performance of these models among patients with chest pain evaluated in an emergency department (ED).

Methods: We compared three scores (DF, CAD consortium basic, and clinical) among 1247 consecutive patients with chest pain who underwent coronary computed tomographic angiography (CTA).
