目的研究冠状动脉粥样硬化性心脏病(coronary heart disease,CHD)患者血清骨形态发生蛋白4(bone morphogenetic protein 4,BMP-4),N1-甲基烟酰胺(N1-methylnicotinamide,me-Nam)和血管生成素样蛋白8(angiopoietinlike protein 8,ANGPTL8...目的研究冠状动脉粥样硬化性心脏病(coronary heart disease,CHD)患者血清骨形态发生蛋白4(bone morphogenetic protein 4,BMP-4),N1-甲基烟酰胺(N1-methylnicotinamide,me-Nam)和血管生成素样蛋白8(angiopoietinlike protein 8,ANGPTL8)水平检测的临床意义。方法选取2018年1月~2020年1月佛山市中医院诊治的86例CHD患者作为CHD组,以健康体检的60例健康人群为对照组,检测CHD组及对照组血清BMP-4,me-Nam,ANGPTL8,血脂及炎症因子水平。比较不同冠状动脉狭窄程度、不同病变支数患者血清BMP-4,me-Nam及ANGPTL8水平。Pearson线性相关分析CHD组患者血清BMP-4,me-Nam和ANGPTL8之间的相关性及三者与Gensini积分、总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)和超敏C反应蛋白(hs-CRP)的相关性。ROC曲线分析血清BMP-4,me-Nam,ANGPTL8及联合检测对CHD组患者的诊断价值。结果与对照组相比,CHD组患者高血压史、糖尿病史占比较高,TC,TG,LDL-C,IL-6,TNF-α及hs-CRP水平明显增高,HDL-C水平明显降低,差异均有统计学意义(t=5.950~28.084,均P<0.05)。与对照组相比,CHD组患者血清BMP-4,me-Nam,ANGPTL8水平明显增高,差异均有统计学意义(t=14.201,13.495,37.538,均P<0.05)。随着Gensini积分升高或病变支数的增加,CHD患者的血清BMP-4,me-Nam,ANGPTL8有逐渐升高的趋势(χ^(2)=80.976,75.688,108.641,均P<0.05)。CHD患者血清BMP-4表达与me-Nam,ANGPTL8表达呈显著正相关(r=0.567,0.610,均P<0.05),me-Nam与ANGPTL8的表达呈显著正相关(r=0.562,P=0.000)。血清BMP-4,me-Nam,ANGPTL8及联合检测的曲线下面积分别为0.707(95%CI:0.601~0.812),0.713(95%CI:0.612~0.833),0.759(95%CI:0.667~0.850)及0.847(95%CI:0.722~0.908),联合诊断的诊断效能大于任一单一指标的诊断效能。结论CHD患者血清BMP-4,me-Nam及ANGPTL8水平升高,三者与血脂、炎症因子、冠状动脉狭窄程度及病变支数有关,检测其水平可为CHD病情评估提供一定参考。展开更多
