Folic Acid and Intensive Antihypertensive Therapy for Hypertension With CSVD

Summary

The primary objectives of this trial are:

1. Efficacy evaluation of amlodipine folic acid tablets:

To assess the effects of amlodipine folic acid tablets 5.8 mg (5 mg amlodipine + 0.8 mg folic acid)versus amlodipine tablets 5 mg in preventing all-cause stroke in cerebral small vascular disease (CSVD) patients with hypertension and elevated homocysteine (Hcy) level.
2. Intensive Antihypertensive Therapy:

To assess the effect of intensive antihypertensive therapy (SBP\<130 mmHg) versus standard antihypertensive therapy (SBP 130-\<140 mmHg) in reducing risk of combined cardio-cerebrovascular events in CSVD patients with hypertension and elevated Hcy level, using two basic anti-hypertensive drugs, amlodipine tablets 5 mg or amlodipine folic acid tablets 5.8 mg.

Conditions

Interventions

DRUG

Amlodipine folic acid 5.8mg+intensive antihypertensive therapy

Amlodipine folic acid tablet 5.8mg, taken daily, in the morning after waking. To achieve target blood pressure(SBP\<130mmHg), this study will provide, if needed, concurrent antihypertensive medications. Patients will be asked to discontinue all prior concurrent medications. Recommended treatment options are described below: 1. Add candesartan 4mg; 2. Add indapamide 2.5mg; 3. Increase dose of candesartan to 8mg; 4. Increase dose of amlodipine to 7.5mg-10mg.
