目的 探讨血浆BNP预测急性肺栓塞患者发生心血管疾病的临床价值。方法 选择2017年1月—2017年12月在我院诊断为急性肺血栓栓塞患者97例为研究对象,根据有无出现心血管并发症分为观察组(21例)和对照组(76例)。比较两组间实验室指标的差异性和相关性,并采用ROC曲线分析BNP预测急性肺栓塞患者发生心血管疾病的临床价值。结果 观察组共出现21例心血管并发症,占21.65%。观察组中BNP、Hs-CRP 、TnI 、AST、CK和DD的浓度分别为(413.01±33.09)(pg/mL)、(20.49±2.88)mg/L、(0.154±0.103)μg/L、(131.23±27.05)U/L、(421.64±50.70)U/L和(1.95±0.18)mg/L,高于对照组(P<0.05)。Spearman相关性分析,血浆BNP水平与Hs-CRP 、TnI 、AST、CK和DD水平呈正相关(r=0.802、0.718、0.683、0.705、0.753,P<0.05)。ROC曲线分析,BNP的AUC面积最高,为0.834(95%CI:0.795~0.935),敏感度和特异度分别为90.5%和87.5%,联合诊断的AUC面积为0.892(95%CI:0.811~0.976),敏感度和特异度分别为84.6%和91.3%。结论 血浆BNP对于预测急性肺栓塞患者发生心血管疾病具有极高临床价值,采取多指标联合检查可以更加有效发现心血管疾病的发生。

Objective To investigate the clinical value of plasma BNP in predicting cardiovascular disease in patients with acute pulmonary embolism. Methods 97 cases of acute pulmonary thromboembolism diagnosed in our hospital from January to December 2017 were selected.The patients were divided into the observation group (21 cases) and control group (76 cases) according to whether there were cardiovascular complications.The differences and correlations of laboratory indexes between the two groups were compared, and the ROC curve was used to analyze the clinical value of BNP in predicting the occurrence of cardiovascular disease in patients with acute pulmonary embolism. Results 21 cases of cardiovascular complications occurred in the observation group, accounting for 21.65%.The concentration of BNP, Hs-CRP, TnI, AST, CK and DD in the observation group were (413.01±33.09) (pg/mL), (20.49±2.88) mg/L, (0.154±0.103) μg/L, (131.23±27.05) U/L, (421.64±50.70) U/L and (1.95±0.18) mg/L, which were higher than those of the control group(P<0.05). Spearman correlation analysis showed that plasma BNP levels were positively correlated with the levels of Hs-CRP, TnI, AST, CK and DD (r=0.802,0.718,0.683,0.705,0.753,P<0.05). The ROC curve analysis showed that the area of AUC of BNP was 0.834 (95%CI:0.795~0.935) of the highest, the sensitivity and specificity were 90.5% and 87.5% respectively. The area of combined diagnosis of AUC was 0.892 (95%CI:0.811~0.976),the sensitivity and specificity were 84.6% and 91.3%, respectively. Conclusion Plasma BNP is of high clinical value for predicting the incidence of cardiovascular disease in patients with acute pulmonary embolism. Multi-index combined examination may be more effective to detect the occurrence of cardiovascular disease.

Methods 342 patients with AHF and 30 healthy persons were selected as observation group and control group. NTpro-BNP, cTnI, hs-CRP and LVEF level of two groups and mortality during the follow-up period were analyzed. Relationship between NTpro-BNP, cTnI, hs-CRP and LVEF, and value of them unitedly predicting mortality of patients were analyzed. Results NTpro-BNP, cTnI, hs-CRP of observation group were higher than that of the control group while LVEF was lower than that of the control group; Compared with T₀, NTpro-BNP, cTnI, hs-CRP of observation group in T₂, T₃, T₄ were reduced while LVEF increased; Patients with more serious heart failure had higher NTpro-BNP, cTnI, hs-CRP and lower LVEF (P<0.05). NTpro-BNP, cTnI, hs- CRP of survived patients in observation group were lower while LVEF was higher(P<0.05). NTpro-BNP,cTnI and hs-CRP of AHF patients were negative correlated with LVEF and value of them predicting good prognosis. Conclusion NTpro-BNP, cTnI, hs-CRP of AHF patients are related to its heart function and the value of them unitedly predicting prognosis is good, thus they may used cardiac function and prognosis evaluation reference index of AHF patient.

Objective To observe and analyze the influence and significance of different doses of nitroglycerin on plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with acute left ventricular failure. Methods One hundred and twenty patients with acute left heart failure were randomly assigned into control group and observation group. Patients in the control group were treated with low dose of nitroglycerin, while patients in the observation group were given high dose of nitroglycerin. NT-proBNP and clinical efficacy in the two groups were observed and compared after treatment. Results After different doses of drug treatment, the overall response rate in the observation group (96.67%) was significantly higher than that in the control group (68.33%), with statistically significant difference (χ²=16.68, P<0.05). Before treatment, NT-proBNP levels were similar, without statistically significant difference (t=0.384, P>0.05). At 6, 12 and 24 hours after treatment, NT-proBNP level was obviously decreased, which was improved than the control group, there were statistically significant differences (t=17.470, 13.988, 13.900, P<0.05). Conclusion Conventional treatment combined high-dose nitroglycerin micro-injection may reduce NT-proBNP indicator levels, relieve symptoms, and have significant clinical effect in patients with acute left heart failure.

Objective To investigate the expressions and clinical significances of atrial brain natriuretic peptide precursor (PRO-BNP), homocysteine (Hcy) and erythrocyte sedimentation rate (ESR) in patients with unstable angina pectoris associated by Left ventricular systolic insufficiency. Methods A total of 130 patients with simple unstable angina pectoris and another 130 patients with unstable angina pectoris associated by left ventricular systolic insufficiency treated during January 2015 and October 2016 were selected as group A and group B respectively,and at the same period,130 healthy persons taking medical examination were selected as the control froup (group C). Serum levels of PRO-BNP,Hcy and ESR were detected in three groups,and the correlation between serums PRO-BNP,Hcy and ESR and left ventricular ejection fraction (LVEF) in group B were analyzed. Results Serum levels of in group A and B were significantly higher than those in group C,and the levels in group B were significantly higher than those in group A. In group B,serum levels of PRO-BNP,Hcy and ESR were significantly increased with rising cardiac function classification. Serum levels of PRO-BNP,Hcy and ESR in group B were negatively correlated with LVEF,but serum levels of Hcy and ESR were positively correlated with PRO-BNP level. Conclusion Serum levels of PRO-BNP,Hcy and ESR in group A and B are significantly correlated with cardiac function in patients with unstable angina pectoris associated by left ventricular systolic insufficiency,so the levels may be used as important indexes for evaluating the severity and prognosis of with unstable angina pectoris associated by left ventricular systolic insufficiency.
