心房颤动患者血清vaspin与心房纤维化血清生化标志物的相关性研究

The correlation study of serum vaspin with atrial fibrosis biochemical markers in patients with atrial fibrillation

目的探讨心房颤动(atrial fibrillation,AF)患者血清脂肪特异性丝氨酸蛋白酶抑制剂(visceraladiposetissue-derived serineproteinase inhibitor,vaspin)与心房纤维化血清生化标志物的相关性。方法选取2021年1月至2022年10月在上海市普陀区人民医院心血管内科就诊且被诊断为AF的住院患者,采用酶联免疫吸附试验(enzyme linked immunosorbent assay,ELISA)测定阵发性房颤(paroxysmal atrial fibrillation,PAF)组、持续性房颤(persistent atrial fibrillation,PeAF)组及健康对照组患者的血清vaspin、Ⅰ型胶原羧基端前肽(C-terminal propeptide of prollagen typeⅠ,PⅠCP)、基质金属蛋白酶-1(matrix metalloproteinase-1,MMP-1)、Ⅲ型前胶原N端肽(N-terminal typeⅢcollagen peptide,PⅢNP)、组织型基质金属蛋白酶抑制剂-1(tissue matrix metalloproteinase inhibitory factor-1,TIMP-1)。分析患者的血清vaspin与上述血清生化标志物的相关性。结果①PeAF组患者的血清vaspin(9.51±1.47)ng/ml、PⅠCP(704.83±120.45)ng/ml、MMP-1(5.92±0.73)ng/ml、PⅢNP(63.34±12.24)ng/ml、TIMP-1(7.56±0.90)ng/ml的水平均显著高于PAF组及对照组(P<0.05);②vaspin与PⅠCP、MMP-1、PⅢNP、TIMP-1在PAF组、PeAF组中均呈显著正相关。结论AF患者血清vaspin水平显著升高,且与心房纤维化血清生化标志物呈正相关,提示vaspin与AF患者心房纤维化密切相关,可作为判别AF纤维化程度的潜在标志物。

Objective To discuss the correlation of serum visceraladiposetissue-derived serineproteinase inhibitor(vaspin)and atrial fibrosis biochemical markers in atrial fibrillation(AF)patients.Methods The subjects were selected from inpatients in Shanghai Putuo District People’s Hospital during January 2021 to October 2022.Enzyme linked immunosorbent assay(ELISA)was used to determine the levels of serum vaspin,C-terminal propeptide of prollagen typeⅠ(PⅠCP),matrix metalloproteinase-1(MMP-1),N-terminal typeⅢcollagen peptide(PⅢNP),tissue matrix metalloproteinase inhibitory factor-1(TIMP-1)of paroxysmal atrial fibrillation(PAF)group,persistent atrial fibrillation(PeAF)group,and control group.The correlation between serum vaspin and the above serum biochemical markers was analyzed.Results①Levels of serum vaspin(9.51±1.47)ng/ml,PⅠCP(704.83±120.45)ng/ml,MMP-1(5.92±0.73)ng/ml,PⅢNP(63.34±12.24)ng/ml,and TIMP-1(7.56±0.90)ng/ml in PeAF group were significantly higher than those of PAF group and control group(P<0.05);②vaspin was significantly and positively correlated with PⅠCP,MMP-1,PⅢNP,TIMP-1 in PAF group and PeAF group.Conclusion Serum vaspin level of AF patients were significantly high and positively correlated with atrial fibrosis biochemical markers,which indicated that serum vaspin level might be closly related to atrial fibrosis in AF patients.It may be a potential marker to identify the degree of fibrosis in atrial fibrillation.
