Additive effect of coronary artery stenosis on left ventricular myocardial strain in patients with essential hypertension: an analysis of cardiac MRI feature tracking.

ABSTRACT:

Background

Hypertension is a major cause of adverse left ventricular (LV) remodeling, and co-existing coronary artery stenosis (CAS) may further compromise myocardial function. This study aimed to evaluate the effect of CAS on LV myocardial strain in patients with essential hypertension (EH) using cardiac magnetic resonance imaging (MRI).

Methods

A retrospective analysis was conducted of 173 EH patients [126 with CAS (CAS+) and 47 without CAS (CAS-)] and 52 controls. LV global radial peak strain (GRPS), global circumferential peak strain (GCPS), global longitudinal peak strain (GLPS), and the peak strain rates were evaluated using feature-tracking technology, and compared among the different stenosis severity groups and controls. Spearman correlation and multivariate linear
