. This study investigates whether serum levels of galectin-3 may reflect impaired mitral annular plane systolic excursion (MAPSE) in patients undergoing cardiac magnetic resonance imaging (cMRI). . Patients undergoing cMRI during routine clinical care were included prospectively within an all-comers design. Blood samples for biomarker measurements were collected within 24 hours following cMRI. Statistical analyses were performed in all patients and in three subgroups according to MAPSE (MAPSE I: ≥11 mm, MAPSE II: ≥8 mm-<11 mm, and MAPSE III: <8 mm). Patients with right ventricular dysfunction (<50%) were excluded. . 84 patients were included in the study. Median LVEF was 59% (IQR 51-64%). Galectin-3 correlated significantly with NT-proBNP ( = 0.42, = 0.0001). Galectin-3 increased significantly according to the different stages of impaired MAPSE ( = 0.006) and was able to discriminate both patients with impaired MAPSE <11 mm (area under the curve (AUC) = 0.645, = 0.024) and <8 mm (AUC = 0.733, = 0.003). Combining galectin-3 with NT-proBNP improved discrimination of MAPSE <8 mm (AUC 0.803, = 0.0001). In multivariable logistic regression models galectin-3 was still associated with impaired MAPSE (MAPSE < 11 mm: odds ratio (OR) = 3.53, = 0.018; MAPSE < 8 mm: OR = 3.18, = 0.06). . Galectin-3 reflects MAPSE being assessed by cardiac MRI.
本研究调查了在接受心脏磁共振成像（cMRI）的患者中，半乳糖凝集素-3的血清水平是否可反映二尖瓣环平面收缩期位移（MAPSE）受损情况。在常规临床护理期间接受cMRI检查的患者以前瞻性、所有患者纳入的设计被纳入研究。在cMRI检查后24小时内采集用于生物标志物测量的血样。对所有患者以及根据MAPSE划分的三个亚组（MAPSE I：≥11毫米，MAPSE II：≥8毫米-<11毫米，MAPSE III：<8毫米）进行统计分析。排除右心室功能不全（<50%）的患者。84名患者被纳入本研究。左心室射血分数（LVEF）中位数为59%（四分位间距51-64%）。半乳糖凝集素-3与N末端B型利钠肽原（NT-proBNP）显著相关（r = 0.42，P = 0.0001）。半乳糖凝集素-3根据MAPSE受损的不同阶段显著升高（P = 0.006），并且能够区分MAPSE<11毫米的受损患者（曲线下面积（AUC）= 0.645，P = 0.024）和<8毫米的患者（AUC = 0.733，P = 0.003）。将半乳糖凝集素-3与NT-proBNP联合使用可改善对MAPSE<8毫米的鉴别诊断（AUC 0.803，P = 0.0001）。在多变量逻辑回归模型中，半乳糖凝集素-3仍与MAPSE受损相关（MAPSE<11毫米：比值比（OR）= 3.53，P = 0.018；MAPSE<8毫米：OR = 3.18，P = 0.06）。半乳糖凝集素-3反映了通过心脏磁共振成像评估的MAPSE。
