Are increased left ventricular strains compensatory effects in lipedema? Detailed analysis from the three-dimensional speckle-tracking echocardiographic MAGYAR-Path Study.

Abstract

Lipedema is a chronic, common but underdiagnosed disease masquerading obesity, with female predominance, characterized by disproportional abnormal adipose tissue distribution of the lower and also upper extremities. The present study was designed to determine whether lipedema is associated with three-dimensional (3D) speckle-tracking echocardiography (3DSTE)-derived left ventricular (LV) deformation abnormalities, and to assess the effects of 1-hour use of medical compression stockings (MCS). The present study comprised 19 female patients with lipedema (mean age: 42.2 ± 12.4 years), compared to 28 age-matched healthy female controls (mean age: 42.0 ± 9.8 years). Lipedema patients showed larger left atrial and LV dimensions and greater LV ejection fraction than controls, without significant difference in other echocardiography variables. Lipedema patients had greater 3DSTE-derived global and mean segmental LV circumferential and area strains than controls. Following 1-hour use of wearing MCS, neither global and nor mean segmental LV strains showed significant impairment or improvement. Increased LV strains could be compensatory effects maintaining LV pumping function in lipedema. Short-term wearing of MCS has no global effect on LV strains.
