Aim To investigate the risk factors of cardiovascular adverse events in hemodialysis patients. Methods We randomly selected 67 cases of endstage renal disease(ESRD) who accepted maintenance hemodialysis in our hospital from January 2009 to December 2009.The patients were divided into two groups according to whether there had cardiovascular adverse events since 5 months ago.The chart of each patient were recorded and analyzed. Results The factors of age,dialysis age,systolic blood pressure,blood cholesterol and low density lipoprotein in cardiovascular events group was significantly higher than the group of non-cardiovascular events(P<0.05). Conclusions Age,dialysis age,systolic blood pressure and low density lipoprotein were the risk factors for cardiovascular adverse events,effectively controlling the blood pressure and lipid levels in dialysis patients was conducive to the prevention of cardiovascular adverse events.
