Abstract
Inflammatory pathways, particularly those involving vascular cell adhesion molecule-1 (VCAM-1), play a central role in post-ischemic myocardial remodeling. However, its relationship with left ventricle (LV) performance or volumetric changes has not been systematically examined. This study aimed to investigate the association between circulating VCAM-1 levels, LV volumes, and LV ejection fraction (LVEF), quantified using three-dimensional echocardiography (3-DE), in patients with acute coronary syndrome (ACS). All patients underwent comprehensive clinical evaluation and 3-DE assessment within the first 24 hours of hospital admission. Concurrently, a full panel of locally available laboratory tests was performed, including serum sampling for VCAM-1 analysis. A follow-up evaluation, comprising repeated biological and echocardiographic measurements, was conducted two months after the index event. A total of 90 patients with ACS (mean age 54 ± 9 years; 75 males) were included in the analysis. Among these, 30 patients (33.3%) had a ≥10% increase in left ventricular end-diastolic volume (LVEDV) at follow-up, indicative of adverse left ventricular remodeling. Baseline VCAM-1 levels were significantly correlated with subsequent changes in LVEDV and LVEF from admission to follow-up (r = -0.42, P < 0.05, and r = -0.43, P < 0.05, respectively). Furthermore, the dynamic changes in VCAM-1 between assessments also showed significant correlations with changes in LVEDV and LVEF (r = 0.41, P < 0.05; r = -0.46, P < 0.05). This study suggests that VCAM-1, an inflammatory biomarker, may be a prognostic indicator of LV remodeling and dysfunction in patients with acute coronary syndromes. The findings support further exploration of VCAM-1 for risk stratification and therapy.
炎症通路,特别是与血管细胞粘附分子-1 (VCAM-1)有关的炎症通路,在缺血后心肌重构中起着核心作用。然而,其与左心室(LV)性能或容积变化的关系尚未得到系统的研究。本研究旨在探讨急性冠脉综合征(ACS)患者循环VCAM-1水平、左室容积和左室射血分数(LVEF)之间的关系,用三维超声心动图(3-DE)量化。所有患者在入院后24小时内均进行了全面的临床评估和3-DE评估。同时,还进行了当地可获得的全套实验室检测,包括血清取样,用于VCAM-1分析。随访评估,包括重复的生物和超声心动图测量,在指数事件发生两个月后进行。共90例ACS患者(平均年龄54±9岁;75名男性)被纳入分析。其中30例(33.3%)患者随访时左室舒张末期容积(LVEDV)增加≥10%,提示左室重构不良。基线VCAM-1水平与入院至随访期间LVEDV、LVEF的变化显著相关(r = -0.42, P < 0.05; r = -0.43, P < 0.05)。此外,VCAM-1的动态变化也与LVEDV和LVEF的变化呈显著相关(r = 0.41, P < 0.05;r = -0.46, P < 0.05)。本研究提示炎症生物标志物VCAM-1可能是急性冠脉综合征患者左室重构和功能障碍的预后指标。研究结果支持进一步探索VCAM-1的风险分层和治疗。
