Left ventricular strain and left atrial strain are impaired during hemodialysis in children

چکیده
We aimed to investigate intradialytic changes in ventricular and atrial function using speckle tracking echocardiography (STE) pediatric hemodialysis (HD). Children with HD vintage > 3 months were enrolled, was performed prior to, during, after HD. STE analyzed GE EchoPAC. Left (LV) global longitudinal strain (GLS), rate (Sr), mechanical dispersion index (MDI) calculated as the average from apical views; diastolic (Ds) Sr 4-chamber tracing; left (LAS) 4- 2-chamber views. A total of 15 patients enrolled at a median age 12 years (IQR 8, 16) 13 9, 25). GLS worsened during (− 15.8 ± 2.2% vs − 19.9 1.9%, p < 0.001). Post-HD associated BP decrease (coefficient = 0.62, 0.01). LV MDI systolic did not change. Ds progressively 8.4% 9.2, 8.0) 11.9% 13.4, 10.3), LAS mid-HD returned baseline post-HD. Ds, DSr, LAS, LASr BV removal or (p 0.1). In conclusions, consistent subclinical dysfunction observed children. Changes change may be related disease progression. Longitudinal study these novel indices unfold effect on long-term cardiovascular health children requiring chronic

Do left atrial strain and strain rate reflect intrinsic atrial function, or are they determined by left ventricular function?
BACKGROUND Left atrial (LA) strain (S) and strain rate (SR) are reported as measures of intrinsic function. AIM Since the LA and left ventricle (LV) are connected through the mitral annulus, we investigated: (1) if deformation indices in the LA are mostly predicted by deformation of the LV; (2) if timings of S and SR events are similar in both the LA and LV; and (3) if alteration of S and SR ...
متن کاملimprovement in left ventricular deformational indices following radiofrequency ablation in patients with tachycardia: a comparative study between avrt and avnrt regarding left ventricular strain and strain rates
conclusions echocardiography and 2d speckle tracking strain imaging shows improvements in left ventricular deformation indices in atrioventricular reentrant tachycardia (avrt) and atrioventricular nodal reentrant tachycardia (avnrt) patients for the mean systolic strain and strain rate at 24 hours and the three-month follow-up. in spite of the normal lvef, even during sinus rhythm, deformation ...

Along the years, the analysis of soccer referees perfomance has interested the experts and we can find several types of studies in literature using in particular cardiac imaging. The aim of this retrospective study was to observe relationship between VO2max uptake and some conventional and not-conventional echocardiographic parameters. In order to perform this evaluation, we have enrolled 20 re...
