Seismocardiographic signal timing with myocardial strain

, 2017
Speckle Tracking Echocardiography (STE) is a relatively new method for cardiac function evaluation. In the current study, STE was used to investigate the timing of heart-induced mostly subaudible (i.e., below the frequency limit of human hearing) chest ...

Towards non-invasive assessment of myocardial work using myocardial stiffness and strain: a human pilot study

International audienceAbstract Aims Myocardial work assessment has emerged as a promising tool for left ventricular (LV) performance evaluation. Existing non-invasive methods for assessing it rely on assumptions on LV pressure and geometry.

Myocardial strain analysis by feature tracking cardiac magnetic resonance to identify subclinical cardiac dysfunction in patients with MINOCA

Journal of Cardiothoracic Surgery
Background To investigate whether feature tracking cardiac magnetic resonance (FT-CMR) can identify subclinical myocardial dysfunction in patients with myocardial infarction with non-obstructed coronary arteries (MINOCA).

Novel non-invasive left ventricular pressure-strain loop imaging demonstrates reduced myocardial work in cardiomyopathy with significant regional variation in non-ischemic cases

, 2018
Background: Non-invasive left ventricular (LV) pressure-strain loop imaging is a novel method of calculating myocardial work (MW). The total area within the pressure-strain loop represents global MW (Figure1A).

Relationship Between Myocardial Strain and Extracellular Volume: Exploratory Study in Patients with Severe Aortic Stenosis Undergoing Photon-Counting Detector CT

Diagnostics
Background/Objectives: Diffuse myocardial fibrosis and altered deformation are relevant prognostic factors in aortic stenosis (AS) patients. The aim of this exploratory study was to investigate the relationship between myocardial strain, and myocardial ...

Impaired myocardial deformation and aortic distensibility by cardiac MRI in girls with Turner syndrome

Scientific Reports
Girls and women with Turner syndrome (TS) suffer from increased risk of cardiovascular diseases. We hypothesized that left ventricular (LV) myocardial strain and aortic elasticity will be impaired in girls with TS.

Association between myocardial layer-specific strain and high 10-year risk of atherosclerotic cardiovascular disease in hypertension—findings from the China-PAR project study

Frontiers in Cardiovascular Medicine
ObjectivesMyocardial layer-specific strain is a sensitive tool for detecting myocardial dysfunction. The objective of this study was to assess changes in the left ventricle (LV) function using myocardial layer-specific strain and its association with 10 ...

A study on the correlation between cardiac magnetic resonance characteristics and myocardial fibrosis in overweight and obese individuals

BMC Medical Imaging
Background Overweight and obesity are major risk factors for adverse cardiovascular outcomes. Cardiac magnetic resonance (CMR) can detect subclinical cardiac dysfunction through myocardial strain and quantify epicardial adipose tissue volume (EATV). This
