Prognostic Value of Strain by Tissue Tracking Cardiac Magnetic Resonance in Myocardial Infarction With Nonobstructive Coronary Arteries.

ABSTRACT:

Background

Strain assessed by cardiac magnetic resonance (CMR) is a key prognostic indicator in myocardial infarction. However, the strain characteristics and prognostic value in myocardial infarction with nonobstructive coronary arteries (MINOCA) with different causes are unclear. This study aims to describe left atrial (LA) and left ventricular strain in patients with MINOCA and evaluate their predictive value for major adverse cardiovascular events (MACEs) in "true MINOCA" cases.

Methods and results

This single-center retrospective study included patients suspected of myocardial infarction who completed CMR during hospitalization. CMR images were used to obtain LA and left ventricular strain via CMR feature tracking. True MINOCA was defined by evidence of ischemia or infa
