The effects of lower body compression on left ventricular rotational mechanics in lymphoedema (from the MAGYAR-Path Study).

Abstract

AimsLower body half compression of bilateral secondary leg lymphoedema (LE) without relevant cardiac insufficiency gives rise to whether external leg compression may influence left ventricular (LV) function. Patients with LE were subjected to baseline two‐dimensional transthoracic echocardiography (2DTTE) for general assessment then three‐dimensional speckle‐tracking echocardiography (3DSTE) before and 1 h after lower body half external compression for LV torsion analysis.Methods and resultsBaseline 2DTTE was performed in the cohort of 25 LE patients, and the results were compared with those of age‐ and gender‐matched 52 healthy controls (mean age: 47.8 ± 12.8 vs. 40.7 ± 14.0 years, 24 women/1 man vs. 49 women/3 men, respectively). 3DSTE was conducted for the assessment of LV rotational mechanics where apical (AR), and basal rotations (BR) were measured before and 1 h after the use of compression class 2 (ccl 2) flat‐knitted medical compression pantyhoses (pressure range: 23–32 mmHg). 2DTTE showed significantly larger LV end‐diastolic volume and ejection fraction among LE patients compared with control subjects (108.3 ± 20.1 vs. 98.5 ± 21.7 mL, 69.8 ± 4.8 vs. 65.5 ± 4.3%, respectively) and notably smaller LV end‐systolic diameter and posterior wall thickness (28.9 ± 3.5 vs. 31.2 ± 3.4 mm, 8.1 ± 1.0 vs. 9.0 ± 1.7 mm, respectively). The results of 20 patients with LE were considered in 3DSTE examinations due to the drop‐out of five probands with technical failures. The data of four LE patients showing significant LV rotational abnormalities were managed separately, and the rotational parameters of the remaining sixteen patients did not differ significantly from those of matched controls except significant reduction of LV BR following the application of medical compression stockings (MCS) (−2.70 ± 1.26 degrees after 1 h use of pantyhose in patient group vs. −4.28 ± 2.18 degrees of the control group; P < 0.05).ConclusionsThe application of compression pantyhoses moderately but significantly decreased LV BR without a remarkable impact on twisting mechanism in LE patients in the absence of LV rotational abnormalities.
