Abstract
OBJECTIVES:
Korean red ginseng (KRG) improves endothelial function and lower blood pressure (BP), which may affect arterial stiffness. The present study evaluated whether KRG treatment could improve arterial stiffness in subjects with hypertension.
SUBJECTS AND METHODS:
Eighty (80) participants with hypertension who were treated with antihypertensive agents were randomly assigned to an active (KRG 3 g/day) or a placebo treatment group in a double-blind manner. Participants were not allowed to change their antihypertensive medications. Systolic BP (SBP) and diastolic BP (DBP) were measured at baseline, and at 1, 2, and 3 months. Arterial stiffness was assessed by the measurement of brachial-ankle pulse wave velocity (baPWV) at baseline, and at 1 and 3 months.
RESULTS:
Thirty (30) subjects in the active group (AG) and 34 subjects in the placebo group (PG) completed 3 months of treatment and then a per-protocol analysis was done. SBP and DBP at baseline, and at 1, 2, and 3 months were not different between the AG and PG (p>0.05). After 3 months of treatment, SBP of AG was not changed from SBP at baseline. However, DBP of AG, and SBP and DBP of PG after 3 months of treatment were significantly reduced (p<0.05). baPWV of both groups was significantly reduced at 1 and 3 months (p<0.05), but was not different between the groups at each time point. Analysis after adjustment for age, time-dependent mean arterial BP, heart rate, and levels of fasting blood glucose and triglycerides showed no significant difference between AG and PG in changes of baPWV from baseline to 1 and 3 months (p>0.05).
CONCLUSIONS:
Three (3) months' treatment with KRG did not improve arterial stiffness in subjects with hypertension.
