Folic Acid and Intensive Antihypertensive Therapy for Cerebrovascular and Cardiovascular Events Prevention Among Patients With Hypertension and Cerebral Small Vascular Diseases (FAITH)----A Multicenter, Randomized, Controlled, Open-label, 2x2 Factorial, Blinded End-point Trial

The primary objectives of this trial are:
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.
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.

OBJECTIVES:

To investigate the actions of amlodipine-folic acid (amlodipine-FA) preparation on hypertension and cardiovascular in renal hypertensive rats with hyperhomocysteinemia (HHcy), so as to provide experimental basis for clinical research of amlodipine folic acid tablets.

METHODS:

Rats model of renal hypertension with HHcy were established. The rats were randomly divided into groups of model, amlodipine, folic acid (FA) and amlodipine-FA of various dosages. Normal rats were used as normal control group. Blood pressure, Hcy as well as plasma NO, ET-1 and hemodynamics were assayed. Histological alterations of heart and abdominal aorta were also examined.

RESULTS:

Compared with the normal group, blood pressure, plasma Hcy, and NO of the rats in model group were significantly increased, while the plasma ET-1 was decreased. Compared with the normal group, the animals in the model group had reduced cardiac function, thickened wall of the aorta and narrowed lumen. In FA group and amlodipine group, the rat plasma NO was increased while ET-1 was decreased, the protective effect of amlodipine-FA group on endothelial cells was further enhanced. In amlodipine group, the rat hemodynamics (LVSP, LVEDP and ±dp/dt_max, et al.) and vascular damage were significantly reduced, while in amlodipine-FA group, the heart function were further improved, and myocardial and vascular hypertrophy were significantly reduced.

CONCLUSIONS:

As compared to amlodipine alone, amlodipine -FA can lower both blood pressure and plasma Hcy, significantly enhancing vascular endothelial function to protect the heart and blood vessel in renal hypertensive rats with HHcy.
