pretestcad: Pretest Probability for Coronary Artery Disease
An application to calculate a patient's pretest
probability (PTP) for obstructive Coronary Artery Disease (CAD) from
a collection of guidelines or studies. Guidelines usually comes from the
American Heart Association (AHA), American College of Cardiology (ACC) or
European Society of Cardiology (ESC). Examples of PTP scores that comes from studies are the
2020 Winther et al. basic, Risk Factor-weighted Clinical Likelihood (RF-CL) and
Coronary Artery Calcium Score-weighted Clinical Likelihood (CACS-CL) models <doi:10.1016/j.jacc.2020.09.585>,
2019 Reeh et al. basic and clinical models <doi:10.1093/eurheartj/ehy806> and
2017 Fordyce et al. PROMISE Minimal-Risk Tool <doi:10.1001/jamacardio.2016.5501>.
As diagnosis of CAD involves a costly and invasive coronary angiography procedure for patients,
having a reliable PTP for CAD helps doctors to make better decisions during patient management.
This ensures high risk patients can be diagnosed and treated early for CAD
while avoiding unnecessary testing for low risk patients.
