Abstract
We conducted a prospective study investigating the relationship between blood pressure values and the risk of cardiovascular disease in patients with end-stage renal diseases. Five hundred fifty-three patients on chronic hemodialysis were followed for 5 years, and the relationship between systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP) and pulse pressure (PP) and the incidence of death and cardiovascular events were evaluated. There were 85 cardiovascular and 88 non-cardiovascular deaths during the 5 years. Fatal and nonfatal cardiovascular events occurred in 205 patients. Factors such as old age, diabetes and electrocardiographic findings of left ventricular hypertrophy and arrhythmia were associated with a high incidence of cardiovascular events as well as the incidence of death. With regard to blood pressure values, only PP was significantly associated with the risk of death (p=0.003). Both SBP and PP showed a significant association with the incidence of cardiovascular events (p=0.004 and p<0.001). In other words, an increase in PP by 10 mmHg corresponded to a 22% increase in cardiovascular events, and a 10 mmHg SBP increase corresponded to a 10% increase in cardiovascular events. In conclusion, PP is a better predictor of death and cardiovascular events than other blood pressure values in chronic hemodialysis patients.
