Ischemic cerebrovascular accident and its secondary renal impairment

Abstract

Background: Renal impairment is one of the most frequent but anticipated potential complications. The objective of this meta-analysis was to evaluate the renal impairment following ischemic cerebrovascular accident (CVA) patients worldwide.Methods: Authors were using meta-analysis. Studies were obtained from several databases like Pubmed, Cochrane, Karger and JNS. Keywords were "renal" or "kidney" and "stroke" and "ischemic". Included studies were full-text observational study or randomized control trial (RCT). Subjects in study were newly diagnosed acute kidney disease (AKI) after ischemic CVA, with age range 18-100 years old. From 425 studies, total 5 studies were eligible for this study.Results: From those 5 studies, it is shown that the pooled risk ratio (RR) for mortality ischemic CVA with AKI was 2.56. AKI appeared insignificantly in both ischemic CVA and intracerebral haemorrhage (ICH) (RR 0.75; p=0.01). The pooled risk ratio had wide heterogeneity (I2 = 0.95) so random effect model was used.Conclusions: Renal impairment and its mortality appeared more frequent in ischemic CVA with AKI. It still needs more multicentre and long-term period researches in the future to get better understanding AKI in ischemic CVA.
