The benefits of implantable cardioverter defibrillator (ICD) implantation in chronic kidney disease (CKD) patients with high sudden cardiac death (SCD) risk are uncertain. To clarify the effects of receiving an ICD in CKD patients, we conducted this meta-analysis to identify the effects of ICDs on patients with CKD, including those on dialysis. We searched the Cochrane library, EMBASE, PubMed, and clinical trials for studies published before July 2016. Eleven studies including 20,196 CKD patients were considered for inclusion. The pooled analysis suggested that patients with an estimated glomerular filtration rate (eGFR) < 60 mL/minute/1.73 m2 would benefit from receiving treatments with ICDs compared with patients without an ICD device (aHR = 0.77; 95% confidence interval [CI], 0.63 to 0.95). This is the first report of a subgroup analysis on the survival rate of ICD implantation in CKD patients according to an eGFR group. The subgroup analysis indicated a similar protective association of ICDs in stage 3 CKD patients (aHR = 0.71; 95%CI, 0.61 to 0.82) compared with the control group. However, there was no significant improvement in all-cause mortality in stage 4 CKD patients (aHR = 1.02; 95%CI, 0.75 to 1.37) or stage 5 CKD patients (aHR = 0.80; 95%CI, 0.60 to 1.31). This is the first meta-analysis reporting that ICD implantation reduces all-cause mortality in stage 3 CKD patients. However, the data do not indicate there is any benefit to ICD implantation in stage 4 or 5 CKD patients.
