LEFT VENTRICULAR STRAIN: SEX- AND AGE-RELATED CHARACTERISTICS AND ASSOCIATIONS WITH CARDIOVASCULAR DISEASES (REVIEW OF LITERATURE)

Атеросклероз, 2017
The standard indicators of function of the left ventricle (LV) (ejection fraction, end-diastolic and end-systolic volumes, of local contractility) depend on the circulation load and partly are subjective.

The effects of myocardial bridging on two-dimensional myocardial strain during dobutamine stress echocardiography

Myocardial bridging (MB) is a common anatomic variant in coronary arteries with unclear functional significance. We evaluated regional myocardial strain by speckle tracking during dobutamine stress echocardiography (DSE) in patients with MB in the left ...

Myocardial mechanical function measured by cardiovascular magnetic resonance in patients with heart failure

Journal of Cardiovascular Magnetic Resonance
: Background: Strain analysis offers a valuable tool to assess myocardial mechanics, allowing for the detection of impairments in heart function. This study aims to evaluate the pattern of myocardial strain in patients with heart failure (HF).

Improved estimation and visualization of two‐dimensional myocardial strain rate using MR velocity mapping

, 2008
Purpose: To estimate regional myocardial strain rate, with reduced sensitivity to noise and velocities outside the region of interest, and provide a visualization of the spatial variation of the obtained tensor field within the myocardium.

Diagnostic efficacy of complexity metrics from cardiac MRI myocardial segmental motion curves in detecting late gadolinium enhancement in myocardial infarction patients

Heliyon
Background: Myocardial segmental motion is associated with cardiovascular pathology, often assessed through myocardial strain features. The stability of the motion can be influenced by myocardial fibrosis.

Interdependence between myocardial deformation and perfusion in patients with T2DM and HFpEF: a feature-tracking and stress perfusion CMR study

Cardiovascular Diabetology
Background Patients with diabetes have an increased risk of developing heart failure with preserved ejection fraction (HFpEF). This study aimed to compare indices of myocardial deformation and perfusion between patients with type 2 diabetes mellitus ...
