Objective        To systematically evaluate the differences of the danger intensity among traditional risk factors for atherosclerotic renal artery stenosis (ARAS).       Methods        We gathered all case-control studies about risk factors for ARAS in the following databases: PubMed

EMBASE

The Cochrane library

CNKI

Wanfang

VIP

CBM until October 14

2013. According to exclude standards

2 reviewers extracted all relevant data from the screened documents independently

and then the extracted date were analyzed by using RevMan 5.2 software.       Results        Seventeen trials were included in the meta-analysis. Meta-analysis showed that: female

hypertension

dyslipidemia

diabetes and the disease of left main coronary artery had relationship with ARAS. Their pooled OR and 95%CI were 1.31 (1.21

1.42)

2.42 (2.18

2.67)

1.55 (1.18

2.05)

1.44 (1.31

1.58)

and 1.86 (1.42

2.37) respectively. Systolic blood pressure also had relationship with ARAS

its SMD’s  95%CI was 11.08 (5.01

17.16). But diastolic blood pressure seemed to have little relationship with ARAS

with its SMD’s  95%CI of 1.46 (-3.19

6.10).       Conclusion        Traditional factors like female

hypertension

dyslipidemia

diabetes

the disease of left main coronary artery and systolic blood pressure are risk factors for ARAS

but diastolic blood pressure have not be considered to having an effect on the incidence of ARAS.
