Demographic data, the Charlson comorbidity index, history of ischaemic heart disease (IHD) and diabetes mellitus (DM) were assessed.Results: A total of 314 patients >= 70 years with stages 4 and 5 CKD were studied. Of these patients, 162 patients had stage 5 CKD at the beginning of follow-up or progressed to stage 5 during the study, and 69 of these patients were treated with dialysis. In the stage 5 group: median age was 77 years (74-81); 48% had IHD; 50% had DM, Charlson 7 (6-9). Kaplan-Meier survival analysis: >= 70 years (93 vs. 69 patients with dialysis, log rank: 15 P= 70 years who began ACKD follow-up from 01/01/2007 to 31/12/2008 were included, and their progression was observed until 31/12/2013. Demographic data, the Charlson comorbidity index, history of ischaemic heart disease (IHD) and diabetes mellitus (DM) were assessed.Results: A total of 314 patients >= 70 years with stages 4 and 5 CKD were studied. Of these patients, 162 patients had stage 5 CKD at the beginning of follow-up or progressed to stage 5 during the study, and 69 of these patients were treated with dialysis. In the stage 5 group: median age was 77 years (74-81); 48% had IHD; 50% had DM, Charlson 7 (6-9). Kaplan-Meier survival analysis: >= 70 years (93 vs. 69 patients with dialysis, log rank: 15 P= 70 years with stages 4 and 5 CKD were studied. Of these patients, 162 patients had stage 5 CKD at the beginning of follow-up or progressed to stage 5 during the study, and 69 of these patients were treated with dialysis. In the stage 5 group: median age was 77 years (74-81); 48% had IHD; 50% had DM, Charlson 7 (6-9). Kaplan-Meier survival analysis: >= 70 years (93 vs. 69 patients with dialysis, log rank: 15 P= 70 years (93 vs. 69 patients with dialysis, log rank: 15 P= 75 years (74 vs. 46 patients with dialysis, log rank: 8.9 P=.003); patients >= 80 (40 vs. 15 patients with dialysis) and p=0,2. Patients receiving dialysis were younger, with a lower Charlson comorbidity index and shorter follow-up time.Conclusions: Our study shows that dialysis treatment improves survival, although this benefit is lost in patients >= 80 years.
