Coronary heart disease pretest probability

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Pretest probability of coronary artery disease is assessed basing upon the age, gender and the symptoms. Patients are stratified into very low, low, intermediate, and high risk for CAD.

Pretest Probability

Data exists for patients of age group 30 - 70 years. It can be assumed that risk/prevalence of coronary artery disease increases with age. Shown below is a tabulated form of pretest probabilities based upon age, gender, and symptoms. (Adapted from the presentation of Robert B. McCully,MD)

Age	Gender	Asymptomatic	Non-Anginal Chest Pain	Atypical Chest Pain	Typical Chest Pain
30 - 39 y	Men	Very Low	Low	Intermediate	Intermediate
