[摘要] 目的 探討血液透析(HD)患者肌钙蛋白T(cTnT)、N-末端脑钠肽(NT-proBNP)与心脏超声联合检查的临床意义。方法 随机选择该院2017年1月—2019年1月收治的HD患者70例进行研究,均进行1年以上随访,根据随访期间有无心血管事件分为两组,其中有心血管事件为观察组(n=28例)、无心血管事件为对照组(n=42例)。两组对象均有完整资料,完成血清cTnT与NT-proBNP检测及心脏超声检查。比较两组血清cTnT与NT-proBNP及心脏超声指标。结果 观察组血清cTnT与NT-proBNP分别为(0.332±0.066)、(304.33±54.37)ng/mL;对照组血清cTnT与NT-proBNP分别为(0.184±0.052)、(264.73±43.94)ng/mL;对比两组cTnT(t=4.207,P<0.05);对比两组NT-proBNP(t=5.886,P<0.05)。观察组LAD(36.95±2.15)mm、LVDd(52.83±4.62)mm、IVST(13.84±2.55)mm、LVEF(52.49±7.56)%;对照组LAD(35.63±2.06)mm、LVDd(48.43±5.03)mm、IVST(10.94±2.13)mm、LVEF(56.84±8.05)%;对比两组LAD(t=2.592,P<0.05);对比两组LVDd(t=2.883,P<0.05);对比两组IVST(t=2.904,P<0.05);对比两组LVEF(t=3.206,P<0.05)。结论 HD患者应用血清cTnT与NT-proBNP检测联合心脏超声检查,可尽早明确有无心血管事件风险,根据检测结果及时评估,积极干预,可避免或减少心血管事件发生。

[Abstract] Objective To explore the clinical significance of combined examination of troponin T (cTnT), N-terminal brain natriuretic peptide (NT-proBNP) and cardiac ultrasound in hemodialysis (HD) patients. Methods Seventy HD patients admitted to our hospital from January 2017 to January 2019 were randomly selected for the study. All were followed up for more than 1 year. According to whether there were cardiovascular events during the follow-up period, they were divided into two groups, of which cardiovascular events were the observation group (n=28 cases) and no cardiovascular events were used as the control group (n=42 cases). Both groups of subjects have complete data, complete the detection of serum cTnT and NT-proBNP and cardiac ultrasound. The serum cTnT and NT-proBNP and cardiac ultrasound indexes were compared between the two groups. Results The observation group's serum cTnT and NT-proBNP were (0.332±0.066) ng/mL and (304.33±54.37) ng/mL, respectively; the control group's serum cTnT and NT-proBNP were (0.184±0.052) ng/mL, (264.73±43.94) ng/mL; comparing the two groups of cTnT(t=4.207, P<0.05); comparing the two groups of NT-proBNP(t=5.886, P<0.05). observation group LAD (36.95±2.15) mm, LVDd (52.83± 4.62) mm, IVST (13.84±2.55) mm, LVEF (52.49±7.56)%; control group LAD (35.63±2.06) mm, LVDd (48.43±5.03) mm, IVST (10.94±2.13) mm, LVEF (56.84±8.05)%; comparing the two groups of LAD(t=2.592, P<0.05); comparing the two groups of LVDd(t=2.883, P<0.05); comparing the two groups of IVST(t=2.904, P<0.05); comparing the two groups of LVEF(t=3.206, P<0.05). Conclusion The use of serum cTnT and NT-proBNP detection combined with cardiac ultrasound in HD patients can determine whether there is a risk of cardiovascular events as soon as possible. According to the test results, timely assessment and active intervention can avoid or reduce the occurrence of cardiovascular events.
综上所述,HD患者应用血清cTnT与NT-proBNP检测联合心脏超声检查,可尽早明确有无心血管事件风险,根据检测结果及时评估,积极干预,可避免或减少心血管事件发生。
