Diagnostic accuracy of strain and strain rate imaging detecting coronary artery disease in a stable chest pain population: a prospective diagnostic accuracy study.

ABSTRACT:

Objectives

Coronary artery disease (CAD) is a major cause of morbidity and mortality worldwide, and detecting CAD in stable chest pain patients is challenging but crucial for early intervention. Strain and strain rate (S/SR) imaging offers a non-invasive method to assess myocardial function and detect coronary stenosis before symptoms occur. In this study, we aimed to demonstrate how effectively and accurately resting strain echocardiography can diagnose CAD.

Design

We conducted a prospective diagnostic accuracy study of patients with chest pain who were referred for CT coronary angiography (CCTA).

Setting

Single-centre study conducted in the University Hospital of North Norway in Tromsø, Norway between 2016 and 2021.

Participants

A total of 510 patients with c
