摘要:
目的 探讨射血分数降低的心力衰竭(HFrEF)患者血清可溶性致癌抑制因子2(sST2)水平与心功能、心脏重构的相关性。 方法 入选2019年7月至2020年9月在昆明医科大学第一附属医院心内科住院的HFrEF患者110例,通过免疫荧光干式定量法检测血清sST2水平,收集超声心动图中反映心功能和心脏结构的参数,包括左室射血分数(LVEF)、室间隔厚度、左房内径、右房长径、左室后壁、右室长径、左室舒张末期容积(LVEDV)、左室收缩末期容积(LVESV)等指标,并计算左室舒张末期容积指数(LVEDVI)和左室收缩末期容积指数(LVESVI)。以血清sST2水平的中位数20.0 ng/mL将研究对象分为低水平组(sST2 < 20.0 ng/mL,n = 55)和高水平组(sST2≥20.0 ng/mL,n = 55)。分析血清sST2水平与心功能、心脏重构指标之间的相关性。 结果 在110例HFrEF患者中,血清sST2水平的中位数为20.0 ng/mL;血清sST2高水平组患者较低水平组患者更易合并慢性肾脏疾病和甲状腺功能异常。与低水平组比较,高水平组患者的D-二聚体、B型利钠肽、血肌酐、尿酸、谷草转氨酶水平更高,右房长径更大,肺动脉收缩压更高(P < 0.05)。血清sST2水平与肺动脉收缩压( r = 0.284,P = 0.003)、右房长径(r = 0.356,P = 0.000)呈正相关。 结论 在HFrEF患者中,血清sST2水平与肺动脉收缩压、右房长径均呈正相关,sST2水平越高,右心房长径越大,肺动脉收缩压越高,提示HFrEF患者sST2水平与右心结构功能相关,血清sST2可能在HFrEF患者的心脏重构中发挥一定作用。 -

Abstract:Objective To investigate the correlation between serum soluble oncogenic inhibitor 2 (sST2) level and cardiac function and remodeling in patients with heart failure (HFrEF) with reduced ejection fraction. Methods A total of 110 patients with HFrEF admitted to the Department of Cardiology, the First Affiliated Hospital of Kunming Medical University from July 2019 to September 2020 were enrolled. Serum sST2 levels were detected by immunofluorescence dry quantitative method, and parameters reflecting cardiac function and structure in echocardiography were collected. Left ventricular ejection fraction (LVEF), interventricular septal thickness, left atrial inner diameter, right atrial length diameter, left ventricular posterior wall, right ventricular length diameter, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and other indicators were calculated. LVEDVI and LVESVI were calculated. The subjects were divided into low level group (sST2 < 20.0 ng/mL, n = 55) and high level group (sST2 ≥20.0 ng/mL, n = 55) according to the median serum sST2 level of 20.0 ng/mL. The correlation between serum sST2 level and cardiac function and cardiac remodeling indexes was analyzed. Results Among 110 HFrEF patients, the median serum sST2 level was 20.0 ng/mL. Patients with higher serum sST2 level were more likely to have chronic kidney disease and thyroid dysfunction than patients with lower serum sST2 level. Patients with higher serum sST2 level had higher D-dimer, B-type natriuretic peptide, creatinine, uric acid, aspartate aminotransferase level, and larger right atrial diameter, higher pulmonary artery systolic pressure than patients with lower serum sST2 level (P < 0.05). Serum sST2 level was positively correlated with pulmonary artery systolic pressure ( r = 0.284, P = 0.003) and right atrial diameter (r = 0.356, P = 0.000). Conclusion In HFrEF patients, serum sST2 level was positively correlated with pulmonary artery systolic pressure and right atrial diameter. The higher sST2 level was, the larger right atrial diameter and pulmonary artery systolic pressure were. In other words, serum sST2 level in patients with HFrEF is correlated with right heart function. Serum sST2 may play an important role in cardiac remodeling in patients with HFrEF. -
