The diagnostic accuracy of two-dimensional strain imaging echocardiography to detect the severity of coronary artery disease in non-ST segment elevation acute coronary syndrome.

ABSTRACT:

Objective

Strain imaging by two-dimensional speckle tracking echocardiography can detect severe coronary artery disease (CAD). This study aims to assess the diagnostic accuracy of various strain parameters in patients with non-ST segment acute coronary syndrome to detect the angiographic severity of CAD and also to compare among them.

Methods

This hospital-based observational study was conducted on 178 patients with NSTEACS and preserved left ventricular ejection fraction who presented in emergency or outdoor from July 2021 to December 2022. We excluded patients with prior coronary revascularization, heart failure, arrhythmia, more than trivial valvular heart disease, or poor acoustic window. Global longitudinal strain (GLS), peak systolic strain (SS), post systolic index (P
