Objective:To explore the risk factors of recent cardiovascular and cerebrovascular events and long-term all-cause mortality in hemodialysis (HD) patients.Methods:The clinical data of two groups of retrospective cohort study, which included newly admitted HD (group A) and maintenance HD (group B) patients respectively, were sourced from the HD Center of Beijing Anzhen Hospital, Capital Medical University. The endpoint events were defined as occurrence of cardiovascular or cerebrovascular events or all-cause mortality at less than 12 mouths of dialysis age in group A, and all-cause mortality in group B. The patients were divided into event group and non-event group based on whether endpoint events occurred during the follow-up period. The baseline and follow-up clinical data within the two groups were compared. Cox regression model was used to analyze the risk factors of endpoint events in HD patients.Results:A total of 104 HD patients were enrolled in group A, with 70 males (67.3%), aged (61.54±14.97) years old. The follow-up time was 12.0 (10.0,12.0) months, and 29 patients (27.9%) had endpoint events. In group A, the event group had a higher proportion of peripheral arterial disease ( χ2=6.067, P=0.014), and lower low-density lipoprotein-cholesterol ( t=-2.316, P=0.023) and body mass index ( t=-2.245, P=0.028) than those in the non-event group. A total of 116 HD patients were enrolled in group B, with 86 males (74.1%), aged (65.89±10.06) years old. The follow-up time was 37.5 (21.0, 59.0) months, and 40 patients (34.5%) had endpoint events. In group B, the event group had lower serum albumin ( t=-3.182, P=0.002) and potassium ( t=-2.532, P=0.013) than those in the non-event group. Multivariate Cox regression analysis showed that high hemoglobin compliance rate ( HR=0.977, 95% CI 0.957-0.998, P=0.031) and high serum albumin ( HR=0.836, 95% CI 0.776-0.901, P<0.001) were protective factors of all-cause mortality in maintenance HD patients. Conclusions:The presence of peripheral arterial disease, low low-density lipoprotein-cholesterol and low body mass index may increase the risk of recent cardiovascular and cerebrovascular events in newly HD patients. Substandard hemoglobin and serum albumin may increase the risk of long-term all-cause mortality in maintenance HD patients.
