摘要
目的:研究慢性心功能不全患者N末端脑钠肽前体(NT-proBNP)和心功能状态在肾小球滤过率(GFR)不同范围内的相关性。方法:连续选择200例慢性心功能不全患者,在病情稳定情况下检测NT-proBNP、血清肌酐水平,评价纽约心功能分级(NYHA),计算GFR。结果:NT-proBNP和NYHA随GFR降低而增加,左室射血分数(LVEF)随GFR降低而降低(均P<0.05);左室舒张末期内径(LVEDd)在不同范围GFR内差异无统计学意义。在GFR水平>45ml/min时,NT-proBNP与NYHA呈正相关,与LVEF呈负相关,与LVEDd无明显相关;在GFR水平<45ml/min时,NT-proBNP与NYHA、LVEF和LVEDd均无明显相关性。结论:慢性心功能不全患者NT-proBNP和心功能状态的关系需考虑不同的肾小球滤过率范围。
Objective:To study the relationship between NT-proBNP and heart functions in patients with chronic heart failure under different levels of glomerular filtration rate(GFR).Method:A total of 120 consecutives was enrolled,serum NT-proBNP and creatinine levels were measured,New York Heart Association(NYHA)classes was evaluated,and creatinine clearance rate(GFR)was calculated.Result:NT-proBNP and NYHA were higher as GFR was lowing,LVEF was lowing as GFR was lowing(P〈0.05),LVEDd was no statistical differences in different GFR ranges.NT-proBNP was positive with NYHA and negative with LVEF when GFR45 ml/min,while,NT-proBNP was non-related to LVEDd.NT-proBNP and NYHA,LVEF,LVEDd were no correlation when GFR 〈45 ml/min.Conclusion:The relationship between NT-proBNP and heart functions in patients with chronic heart failure should consider different levels of glomerular filtration rate.
