【Abstract】 Two hundred and seventy-six patients with essential hypertension observed 1～1.5 years before had randomly reexamined 113 of them with the same items andmethods.Comparative analysis was made as follows:1.According to PRA and ATII typing,the results of the first and the secondexamination were compared.The stabilities were higher in the normal types(68.3%and 60.8% respectively).In evaluating the types of indiviual patient among the 113 cases,12 cases areboth normal,1 case is of high type and 1 case is of low type.The total stabilityrate is 12.4%.We conclude that typing by a single index,whether PRA or ATII,islimited in clinical use.2.Twenty-four hours urinary sodium excretion is lower and the potassium excre-tion is higher than that of the normal control group in the first examination theyreturn to normal in the second examination.This changes might be related to thetreatment during the period of 1～1.5 years.3.Correlation between PRA and ATII in patients group is positive(r=0.2564,P<0.005)in the first exmination,but no correlation in the second examination(r=0.041,P>0.005)which is similar to the normal control group(r=0.079,P>0.05).更多还原
