Hypereosinophilic syndrome (HES) and immunoglobulin light-chain amyloidosis (ALA) are two, rare haematological disorders associated with cardiac alterations.
The goal of the present study was a comparative assessment of left ventricular (LV) deformational parameters in HES and ALA patients using three-dimensional speckle-tracking echocardiography (3DSTE).
In the present study, results of 10 HES patients (mean age: 60.9 ± 14.7 years) and 19 ALA patients (mean age: 63.4 ± 7.8 years, 13 males) were analysed. The control group contained 13 age- and gender-matched healthy adults (mean age: 59.2 ± 4.3 years, 5 males). All patients underwent a complete two-dimensional Doppler echocardiography followed by 3DSTE.
All basal segmental LV strains were significantly reduced in ALA patients as compared to the control group. Global and mean segmental LV longitudinal strain (LS) values of ALA patients proved to be significantly decreased as compared to those of the healthy control group. During comparison of HES patients and healthy controls, significant difference could be detected in global LV-LS, while segmental basal LV-LS was also significantly reduced in HES patients. Basal LV radial and 3D strains showed significant differences when parameters of HES and ALA patient groups were compared.
3DSTE is a feasible tool for the detailed assessment of LV deformation in HES and ALA patients. Significant LV deformational abnormalities could be detected in both groups. In the case of ALA, these abnormalities are more prominent. Orv Hetil. 2020; 161(5): 169-176.
