The aims of this study were to compare global longitudinal strain of the left ventricle (LV-GLS) and reservoir strain of the left atrium (R-LAS) values between patients with acute decompensation of chronic heart failure (HF) and a control group.
Sixteen patients admitted to our ward for acute decompensation of HF were enrolled in this study. Transthoracic echocardiography (TTE) with two-dimensional speckle-tracking analysis (2D ST) was performed in each patient. The patients were divided into two subgroups according to the value of left ventricular ejection fraction (EF) using a cut-off value of ≤40% to distinguish heart failure with reduced ejection fraction (HFrEF) from heart failure with preserved ejection fraction (HFpEF). The control group consisted of 16 individuals without a history of cardiovascular disease, each of whom underwent 2D ST analysis as well.
We found that LV-GLS and R-LAS were significantly lower in both the HFrEF and HFpEF subgroups in comparison with the control group (LV-GLS: -13.4 ± 4.7% vs. -19.7 ± 2.5%, ˂ 0.05; R-LAS: +12.2 ± 6.9% vs. +40.3 ± 7.4%, ˂ 0.05). Furthermore, there was a significant difference in LV-GLS (-9.6 ± 3.2% vs. -15.2 ± 4.3%, ˂ 0.05) but not in R-LAS (+13.7 ± 8.6% vs. +11.4 ± 6.2%) between the HFrEF and HFpEF subgroups.
Our study demonstrated a significant difference in LV-GLS and R-LAS in all enrolled HF patients compared to the control group. There was also a significant difference in LV-GLS between the HFrEF and HFpEF subgroups.
本研究旨在比较慢性心力衰竭(HF)急性失代偿患者与对照组之间左心室整体纵向应变(LV-GLS)和左心房储存应变(R-LAS)值。
本研究纳入了16名因HF急性失代偿入住我院病房的患者。对每位患者进行经胸超声心动图(TTE)检查,并采用二维斑点追踪分析(2D ST)。根据左心室射血分数(EF)值将患者分为两个亚组,以≤40%为临界值区分射血分数降低的心力衰竭(HFrEF)和射血分数保留的心力衰竭(HFpEF)。对照组由16名无心血管疾病史的个体组成,他们也均接受了2D ST分析。
我们发现,与对照组相比,HFrEF和HFpEF亚组的LV-GLS和R-LAS均显著降低(LV-GLS:-13.4±4.7%对-19.7±2.5%,˂0.05;R-LAS:+12.2±6.9%对+40.3±7.4%,˂0.05)。此外,HFrEF和HFpEF亚组之间LV-GLS存在显著差异(-9.6±3.2%对-15.2±4.3%,˂0.05),但R-LAS无显著差异(+13.7±8.6%对+11.4±6.2%)。
我们的研究表明,与对照组相比,所有纳入的HF患者的LV-GLS和R-LAS存在显著差异。HFrEF和HFpEF亚组之间LV-GLS也存在显著差异。
