About this study

This is a multi-center, randomized, double-blind, double-dummy, controlled clinical trial. This trial will include 32,000 Chinese men and women with hypertension (H-type hypertension), MTHFR 677 CC or CT genotype, elevated plasma total homocysteine (tHcy ≥10µmol/L), and insufficient serum folate levels (\<12ng/mL). The participants will be first stratified by their MTHFR 677 genotype (CC vs. CT), then randomized to one of two treatment groups in a 1:1 ratio. Group A: amlodipine tablet (5mg), taken orally, once daily, serving as active comparator. Group B: amlodipine folic acid 5.8mg tablet (5mg amlodipine and 0.8mg folic acid), taken orally, once daily. The treatment period is five years and primary endpoint is first ischemic stroke.
