主要研究背景及目的

微量白蛋白尿可反映肾小球毛细血管壁内皮损伤,是早期肾损伤的标志之一。也是卒中的一个强有力的预测因子。肾功能的另一种标志物胱抑素C与心血管疾病和死亡的关联性很强。近期的一项大型前瞻性研究(ARIC)表明,联用这两种标志物能提高对心血管事件的预测能力。然而,未见联用eGFRcys和蛋白尿与脑血管疾病预后的相关性研究。 本研究的目的是探讨: (1)在卒中人群中,分析联合eGFRcys与ACR对于预测全因死亡、卒中复发和卒中致残、复合血管事件的风险的意义。 (2)对高血压/糖尿病/年龄进行分层,研究与卒中结局(全因死亡、卒中复发、卒中致残、复合血管事件)的关系。

方法

1、ACR分组方法: (1)ACR<10,10-29,≥30(mg/g) (2)三分位数(从低到高):Tertile 1,Tertile 2,Tertile 3。 2、eGFRcys分组方法:≥105,90-104,75-89,60-74,30-59,≤30 ml/min/1.73m2; 3、分别以eGFRcys90-104ml/min/1.73m2以及ACR <10mg/g作为对照;对于ACR每种eGFRcys类别的全因死亡、卒中复发、卒中致残、复合血管事件的发生率 校正因素:年龄、性别、总胆固醇水平,糖尿病,冠心病,吸烟,高血压,hs-CRP,体重指数。eGFR间的相互作用用ACR作为一个连续的和分类变量,用似然比检验比较模型。 4、以ACR<10mg/g或ACR-Tertie1为对照组,采用Cox回归模型比较不同ACR水平经高血压/糖尿病/年龄分层后与缺血性卒中预后的关系。多变量校正包括eGFR、性别、年龄、NIHSS评分、血脂异常、吸烟、心脏病、房颤等。

结论

Both decreased eGFRcys and albuminuria are independent risk factors for all-cause death and poststroke disability. Combining the two markers is useful for improving risk stratification even in those without chronic kidney disease.

主要结果

Both reduced eGFRcys and increased ACR were independently associated with higher incidences of all-cause death and poststroke disability (p < 0.01). Mildly decreased eGFRcys (60–89 mL/ min/1.73 m2) is associated with increased risk of all-cause death and poststroke disability in the presence of high-normal ACR (10–29 mg/g). Patients with both eGFRcys <45 mL/min/1.73 m2 and ACR ≥30 mg/g at baseline had a 6.8-fold risk for all-cause mortality and 3.6-fold risk for poststroke disability, compared with patients with eGFRcys of 90–119 mL/ min/1.73 m2 and ACR <10 mg/g. In addition, increased ACR was associated with recurrent stroke and CVD composite event, while reduced eGFRcys showed no relationship with these outcomes.
