Atherosclerotic renal artery stenosis: association with emerging vascular risk factors.
キーワード
概要
BACKGROUND
The established risk factors for atherosclerotic renal artery stenosis (ARAS) include hypertension, diabetes mellitus, dyslipidemia, obesity, smoking, old age and family history. In the last few years, several emerging risk factors have been proposed as predictors of ARAS, namely homocysteine, fibrinogen, C-reactive protein, lipoprotein(a) and creatinine.
METHODS
We searched Pubmed/Medline for studies investigating the prognostic value of each of these emerging risk factors in ARAS.
RESULTS
Creatinine and C-reactive protein seem to be the most promising predictors of ARAS, whereas the prognostic value of homocysteine, lipoprotein(a) and fibrinogen is not yet fully determined.
CONCLUSIONS
The establishment of a definite role for these emerging risk factors could result in earlier recognition and/or better management of ARAS with potential regression/slowing down of progression of stenosis. Modifying these markers may also improve the therapeutic approach of the associated systemic atherosclerosis in these high-risk patients. Future trials should focus on the effect of different classes of drugs (e.g. statins and fibrates) on the levels of the emerging risk factors and the association with ARAS progression.
