Three-dimensional versus two-dimensional strain for the assessment of myocardial function: A case series

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017
Introduction: Two-dimensional (2D) strain assessment is an important diagnostic and prognostic tool in various clinical conditions, particularly coronary artery disease (CAD). However, these measurements are limited in that the information is obtained in

Global and regional extracellular volume and myocardial circumferential strain correlate significantly in a heterogeneous patient population [PDF]

Journal of Cardiovascular Magnetic Resonance, 2016
Background Myocardial extracellular volume (ECV) quantification by cardiovascular magnetic resonance (CMR) T1 mapping technique has shown great promises in detecting diffuse fibrosis and interstitial diseases of the myocardium. In hypertensive and left ventricle hypertrophy (LVH) patients, increased ECV has been found to be associated with impaired ...

Effect of low dose intracoronary alteplase on global circumferential strain (myocardial strain CMR substudy from the T-TIME trial)

European Heart Journal, 2021
Abstract Background Microvascular obstruction affects half of patients with ST-segment elevation myocardial infarction (STEMI) and confers an adverse prognosis. Feature-tracking (FT) cardiac magnetic resonance (CMR) allows myocardial strain assessment from standard cine images without the need for ...

Segmental strain for scar detection in acute myocardial infarcts and in follow-up exams using non-contrast CMR cine sequences

BMC Cardiovascular Disorders, 2022
Background The purpose of the study was to investigate feasibility of infarct detection in segmental strain derived from non-contrast cardiac magnetic resonance (CMR) cine sequences in patients with acute myocardial infarction (AMI) and in follow-up (FU)

Image Feature Determinants of Global and Segmental Circumferential Ventricular Strain From Cine CMR

JACC: Cardiovascular Imaging, 2015
Myocardial circumferential strain is a direct measure of tissue function that, unlike ejection fraction, is not directly influenced by ventricular size and shape. Strain estimated from standard cine cardiac magnetic resonance (CMR) steady-state free precession (SSFP) images using image ...

Association Between Left Ventricular Mechanical Deformation and Myocardial Fibrosis in Nonischemic Cardiomyopathy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background In patients with nonischemic cardiomyopathy, nonischemic fibrosis detected by late gadolinium enhancement (LGE) cardiovascular magnetic resonance is related to adverse cardiovascular outcomes.

Prediction of Deterioration of Left Ventricular Function Using 3‐Dimensional Speckle‐Tracking Echocardiography in Patients With Left Bundle‐Branch Block

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Previous studies have demonstrated that 2‐dimensional (2D) global longitudinal strain (GLS) is associated with cardiovascular outcomes in patients with left bundle‐branch block.

Comparison of global and regional myocardial strains in patients with heart failure with a preserved ejection fraction vs hypertension vs age-matched control

Cardiovascular Ultrasound, 2020
Background With an increasing clinical importance of the treatment of the heart failure (HF) with preserved ejection fraction (HFpEF), it is important to be certain of the diagnosis of HF. We investigated global and regional left ventricular (LV) strains

Left ventricular myocardial function in hemodialysis and nondialysis uremia patients: a three-dimensional speckle-tracking echocardiography study. [PDF]

PLoS ONE, 2014
BACKGROUND: Several studies have demonstrated that uremic patients who have preserved left ventricular ejection fraction (LVEF) could still have the potential for systolic dysfunction.
