The efficacy of olmesartan on fibrinolytic capacity has not been studied yet. Therefore, the aim of the present study was to investigate the efficacy of olmesartan on hemostatic/fibrinolytic status by measuring plasma level of plasminogen activator inhibitor-1 (PAI-1) and soluble thrombomodulin levels in patients with hypertension. Forty-two consecutive, newly diagnosed (25 women and 17 men with a mean age of 48 ± 8 years) patients with untreated essential hypertension were included in the study. Olmesartan medoxomil (20 mg/day) was started and the patients were followed up for 6 months. Baseline biochemical variables, thrombomodulin, and PAI-1 levels were compared with the levels of these variables measured at the end of the 6-month follow-up period. After 6 months of treatment with olmesartan medoxomil, there was a significant reduction in systolic and diastolic blood pressure (from 159.5 ± 10.9 to 134.6 ± 12.7 mmHg and from 98.0 ± 6.3 to 83.9 ± 7.0 mmHg, respectively). Mean plasma PAI-1 and thrombomodulin levels were also significantly decreased (59.73 ± 41.91 vs. 48.60 ± 33.65 ng/ml, P = 0.001 and 8.09 ± 2.29 vs. 6.92 ± 1.42 μg/l, P < 0.001, respectively). Olmesartan medoxomil decreased plasma PAI-1 and thrombomodulin levels after 6 months of therapy, indicating a favorable effect on fibrinolytic capacity in patients with essential hypertension.
[Show abstract][Hide abstract] ABSTRACT: The fermented soybean product natto is a popular traditional food in Japan and is considered a health supplement. NKCP(®), a natto-derived dietary food supplement whose main component is bacillopeptidase F, has antithrombotic, fibrinolytic, and blood pressure-lowering effects. We examined whether daily intake of NKCP(®) effectively improves subjective symptoms in patients with lifestyle diseases in this cross-over, double-blind study. Fermented soya extract with subtilisin NAT (nattokinase) as the main component was used as an active placebo. A 4-week course of NKCP(®) significantly decreased the visual analog scale (VAS) score for shoulder stiffness from 42.3 to 32.4 (P=0.009), the VAS score for low back pain from 25.5 to 18.8 (P=0.02), and the VAS score for coldness of the extremities from 33.1 to 25.7 (P=0.002). However, no significant difference was found in the VAS score for headache. After a 4-week course of active placebo, no significant changes in the VAS score were found for any symptoms. The significant improvement in the symptoms secondary to blood flow disturbance was caused by the improvement in blood flow by NKCP(®). The use of dietary supplements based on the Japanese traditional food natto helps to relieve subjective symptoms for patients with lifestyle diseases receiving medical care.
