Preload Dependency of 2D Right Ventricle Speckle Tracking Echocardiography Parameters in Healthy Volunteers: A Prospective Pilot Study

“…Our study has several limitations: first, it is possible that infusion of larger volume would have led to significant changes in 2D-STE parameters or in 2D conventional parameters. However, our results were comparable to those of the study using passive leg raising, which is a dynamic manoeuvre allowing to mobilize 300 mL of blood in order to induce a change in preload [ 11 , 15 ]. Moreover, different shapes, body compositions, and basal circulating states of the subjects may have influenced FC results.…”

“…To our knowledge, there are few data on RV preload dependency of 2D-STE parameters in healthy volunteers. Garcia-Lopez et al [ 15 ] reported that strain analysis was reproducible (ICC 0.773) and sensitive to detect differences in RV4CLS after a passive leg-raising manoeuvre in 31 healthy volunteers. However, the strain analysis was not performed in the RV apical view but by with analysis of the six segments in a classical four-chamber view.…”

Epicardial adipose tissue thickness is related to early subclinical myocardial dysfunction, particularly in patients with type 2 diabetes mellitus: a case control study

“…The more negative strain value the better myofibril shortening. In the clinical practice, longitudinal strain (deformation in the base-apex direction) is useful for evaluating left ventricle contractile function [2]. Some cardiometabolic conditions like type 2 Diabetes Mellitus (t2DM), insulin resistance or obesity may induce cardiac myofibrillary dysfunction [3][4][5].…”

“…Атеросклеротичною бляшкою вважають локальну структуру, яка виступає в просвіт артерії не менше ніж на 0,5 мм, або збільшення ТКІМ на 50% порівняно з відповідним показником в навколишньому оточенні, або ТКІМ>1,5 мм [20].…”
