目的:探讨N末端B型钠尿肽前体(NT-proBNP)与老年心功能不全的相关性。方法将收集的老年心功能不全患者100例作为试验组,选取同期入院接受心脏检查结果正常的同年龄段的患者80例作为对照组,采用免疫放射法测定NT-proBNP水平,动态观察NT-proBNP水平与老年心功能不全患者心功能变化及预后的相关性。结果试验组患者NT-proBNP水平、左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)、心肌做功指数(Tei指数)明显高于对照组,而左心室射血分数(LVEF)、左心室短轴缩短率(LVFS)、E/A比值明显低于对照组,两组间所有参考指标比较差异均有显著性(P均<0.05);试验组患者NT-proBNP水平、LVEDD、LVESD、Tei指数随心功能级别的升高逐渐升高,LVEF、LVFS、E/A比值随心功能级别降低逐渐降低,经方差分析,差异具有显著性(P<0.05);LVEDD、LVESD、Tei指数与NT-proBNP水平呈正相关,影响大小顺序为LVESD、LVEDD、Tei指数。LVEF、LVFS以及E/A比值与NT-proBNP水平呈负相关,影响大小顺序为E/A比值、LVEF、LVFS。结论 NT-proBNP与老年心功能不全各项指标密切相关,心功能不全级数越高,NT-proBNP水平越高。
目的:探討N末耑B型鈉尿肽前體(NT-proBNP)與老年心功能不全的相關性。方法將收集的老年心功能不全患者100例作為試驗組,選取同期入院接受心髒檢查結果正常的同年齡段的患者80例作為對照組,採用免疫放射法測定NT-proBNP水平,動態觀察NT-proBNP水平與老年心功能不全患者心功能變化及預後的相關性。結果試驗組患者NT-proBNP水平、左心室舒張末期內徑(LVEDD)、左心室收縮末期內徑(LVESD)、心肌做功指數(Tei指數)明顯高于對照組,而左心室射血分數(LVEF)、左心室短軸縮短率(LVFS)、E/A比值明顯低于對照組,兩組間所有參攷指標比較差異均有顯著性(P均<0.05);試驗組患者NT-proBNP水平、LVEDD、LVESD、Tei指數隨心功能級彆的升高逐漸升高,LVEF、LVFS、E/A比值隨心功能級彆降低逐漸降低,經方差分析,差異具有顯著性(P<0.05);LVEDD、LVESD、Tei指數與NT-proBNP水平呈正相關,影響大小順序為LVESD、LVEDD、Tei指數。LVEF、LVFS以及E/A比值與NT-proBNP水平呈負相關,影響大小順序為E/A比值、LVEF、LVFS。結論 NT-proBNP與老年心功能不全各項指標密切相關,心功能不全級數越高,NT-proBNP水平越高。

Objective Study of N terminal B type natriuretic peptide precursor (NT-proBNP) in elderly patients with heart failure correlation. Method Collected 100 old heart function insufifciency patients as test group, selected the same hospital cardiac examination and the results of normal section of the same age in 80 cases as control group, NT-proBNP levels were measured by RIA, correlation between the change of heart function and prognosis of dynamic observation of NT-proBNP in elderly patients with heart failure patients. Result The test group NT-proBNP, left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), myocardial performance index (Tei index) were signiifcantly higher than that in control group, and the left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS) and E/A ratio were signiifcantly lower than those in the control group. Between the two groups were all reference index issigniifcant difference (P<0.05);elevated NT-proBNP level in test group, LVEDD, LVESD, Tei index of heart function level gradually increased, LVEF, LVFS, E/A ratio decreased heart function level decreased gradually, through analysis of variance between levels of comparative difference was signiifcant (P<0.05);there was positive correlation between LVEDD, LVESD, Tei index and NT-proBNP level effects in the order of LVESD, LVEDD, Tei index. LVEF, LVFS and E/A ratio was negatively correlated with NT-proBNP level, factor in the size of the order E/A ratio, LVEF, LVFS. Conclusion Closely related to N end B precursor in elderly patients with cardiac function of natriuretic peptides not all indicators, heart function not entire series is higher, the higher the NT-proBNP level.
