Why the study?
The study aimed to investigate conventional, Doppler, and speckle tracking echocardiography for assessing LV myocardial function in hemodialysis patients with preserved LVEF and evaluate the effect of a single hemodialysis session on LV systolic and diastolic function.
Does a single hemodialysis session affect left ventricular myocardial function assessed by speckle tracking imaging in hemodialysis patients with preserved LVEF?
Does a single hemodialysis session affect left ventricular myocardial function assessed by speckle tracking imaging in hemodialysis patients with preserved LVEF?
Speckle tracking imaging can detect subclinical left ventricular dysfunction and its improvement following preload reduction from hemodialysis in patients with preserved ejection fraction.

Supports speckle tracking to detect subclinical changes after hemodialysis; leaves open whether findings alter management in preserved LVEF.
INTRODUCTION: our aim was to investigate the value of conventional echocardiography, pulsed Doppler and speckle tracking imaging (STI) analysis in the assessment of the left ventricular (LV) myocardial function in hemodialysis (HD) patients with preserved LV ejection fraction and to evaluate the effect of a single HD session on the LV systolic and diastolic functions. METHODS: the study population consisted of 30 chronic HD patients. Echocardiography and Doppler studies were performed before and after HD. The LV global longitudinal, circumferential and radial strains were measured with two and three-dimensional STI. RESULTS: after HD, LV dimensions, left atrium (LA) area, systolic pulmonary arterial pressure and inferior vena cava diameter decreased significantly. The peak mitral E velocity, the E/A ratio of the mitral inflow and the lateral E/E´ ratio decreased also significantly. The LV and LA volumes index and LV mass index (LVMi) decreased remarkably after HD. The 3D- LV and LA ejection fractions were unchanged after HD. Although, 3D-estimated LVEF seemed to be preserved in the HD patients, the 2D and 3D- strain rates were decreased in all directions. The global strain values improved in all directions after a single HD session. Inverse correlations were found between the LVMi, serum BNP and LV global longitudinal strain. CONCLUSION: in HD patients with preserved LV ejection fraction, the STI analysis may add important information concerning the subclinical LV dysfunction.
