摘要
目的探讨BNP与Swan-Ganz漂浮导管所测得的各项血流动力学指标的相关性。方法选取2007年1～10月入住我院心内科的23例住院患者做血清BNP定量检测并置入Swan-Ganz漂浮导管,测定中心静脉压（CVP）,肺动脉压（PAP）,肺毛细血管压（PCWP）,计算心脏指数（CI）,每搏搏血量（SV）,左室每搏做功指数（LVSWI）,收集数据做多元回归分析,用ANOVA方差分析做相性分析。结果23例患者BNP均数=（266.19±362.51）pg/ml;CVP均数=（5.46±5.01）mmHg,与BPN的相关系数R=0.30,P=0.03;PAP均数=（21.26±9.81）mmHg,与BNP的相关系数R=0.09,P=0.16;PCWP均数=（13.86±10.65）mmHg,与BNP的相关系数R=0.16,P=0.03,CI均数=（2.26±0.56）L/（min·m^2）,与BNP的相关系数R=0.08,P=0.20;SV均数=（51.79±13.70）ml/beat,与BNP的相关系数R=-0.08,P=0.79;LVSWI均值=（30.62±14.16）g/（m·m^2）,与BNP的相关性R=-0.01,P=0.93。结论BNP的水平与有创血流动力学指标检测相比有简便、无创、迅速经济的优势,可以大大提高临床做出诊断的效率。
Objective To explore the correlation between BNP level and parameters of invasive hemodynamic examination with Swan-Ganz＇s flowing balloon catheter.Methods 23 patients were measured plasma brain natriuretic peptide（BNP）levels and measured invasive hemodynamic parameters with Swan-Ganz catheter,such parameters include CVP、PAP、PCWP、CI、SV and LVSWI.All data were analysed by multiple regression and ANOVA test.Results The average level of BNP is（266.19±362.51）pg/ml;mean CVP=（5.46±5.01）mmHg,R=0.30,P=0.03;mean PAP=（21.26±9.81）mmHg,R=0.09,P=0.16;mean PCWP=（13.86±10.65）mmHg,R=0.16,P=0.03;mean CI=（2.26±0.56）L/min/m^2,R=0.08,P=0.20;mean SV=（51.79±13.70）ml/beat,R=-0.08,P=0.79;mean LVSWI=（30.62±14.16）g/（m·m^2）,R=-0.10,P=0.93.Conclusion BNP had positive correlations with CVP、PAP、PCWP and CI.BNP had negative correlation with SV、LVSWI.
