The purpose of this trial is to confirm that enalapril maleate and folic acid tablets is more effective in preventing renal function decline among the patients with primary hypertension when compared to enalapril maleate.
Name: Enalapril maleate and folic acid tablets
Name: Enalapril maleate
Description: Renal function decline was defined based on one of more of the following : (1) A certain drop in eGFR, was defined as a drop in GFR category (≥90[G1], 60-89[G2], 45-59[G3a], 30-44[G3b], 15-29[G4], <15[G5] ml/min/1.73m2) accompanied by a 25% or greater drop in eGFR from baseline; (2) Rapid progression, was defined as a sustained decline in eGFR of more than 5 ml/min/1.73m2/yr.
Measure: Renal function decline Time: Serum creatinine was examined at baseline and at the final visit (5 years) of the trial.Description: The composite endpoint is consisted of: 1)End stage renal disease (ESRD);2)Doubling of serum creatinine; and 3)Renal disease-induced death.
Measure: A composite of renal events. Time: Every 3 months during the trial, up to 5 yearsAllocation: Randomized
Parallel Assignment
There is one SNP
The composite endpoint is consisted of: 1)End stage renal disease (ESRD);2)Doubling of serum creatinine; and 3)Renal disease-induced death..
