Conditions

Summary

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.

Plain Language Summary

Simplified for easier understanding

This trial is studying whether taking folic acid supplements alongside blood pressure medication can help prevent stroke in people with high blood pressure and a specific genetic variation (MTHFR 677 CC or CT) that affects how the body processes folate. You may be eligible if: you are between 45 and 74 years old; you have a diagnosis of high blood pressure and are being treated for it; you have the MTHFR 677 CC or CT gene type; your homocysteine level is elevated (10 or more); and your folate level is lower than normal. You may NOT be eligible if: you have a history of stroke, heart attack, heart failure, irregular heart rhythm, or severe kidney disease; you have serious liver, digestive, or respiratory conditions; you have taken folic acid supplements regularly in the past 3 months; or you are pregnant or breastfeeding. Talk to your doctor to see if this trial is right for you.
