在几项补充辅酶Q10(CoQ 10)的临床研究中观察到心血管发病率和死亡率的改善。我们阐明了辅酶Q10对某些可能影响心脏病进展的止血参数的影响。12头约克郡猪随机接受20天的辅酶Q10或安慰剂的饮食补充。在基线和喂养期结束时采集血样。在方案结束时,安慰剂组的止血参数无显著差异。在补充CoQ 10的组中,在喂养期后注意到总血清CoQ 10水平显著增加(从0.39 +/-0.06至0.96 +/-0.04微克/毫升,p < 0.001)。我们观察到显著抑制ADP诱导的血小板聚集(-9.9%)和降低血浆纤维连接蛋白(-20.2%)、血栓素B2(TXB 2,-20.6%)、前列环素(-23.2%)和内皮素-1(ET-1,-17.9%)水平。补充辅酶Q10后,天然抗血栓药物[抗凝血酶-III(AT-III),蛋白S和蛋白C]的血浆浓度没有变化。辅酶Q10补充剂的剂量为200毫克,每天与轻度抗聚集的变化,在止血概况。辅酶Q10的临床有益作用可能部分与血栓性并发症的发生率降低有关。
Improved cardiovascular morbidity and mortality have been observed in several clinical studies of dietary supplementation with coenzyme Q10 (CoQ10). We elucidated the effect of CoQ10 on certain hemostatic parameters that may influence the progression of heart disease. Twelve Yorkshire swine were randomized to receive diet supplementation with either CoQ10 or placebo for 20 days. Blood samples were obtained at baseline and at the end of the feeding period. At the end of the protocol, there were no significant differences in hemostatic parameters in the placebo group. A significant increase in total serum CoQ10 level (from 0.39 +/- 0.06 to 0.96 +/- 0.04 microgram/ml, p < 0.001) was noted after the feeding period in the CoQ10-supplemented group. We observed significant inhibition of ADP-induced platelet aggregation (-9.9%) and a decrease in plasma fibronectin (-20.2%), thromboxane B2 (TXB2, -20.6%), prostacyclin (-23.2%), and endothelin-1 (ET-1, -17.9%) level. There were no changes in the plasma concentrations of the natural antithrombotics [antithrombin-III (AT-III), protein S, and protein C] after CoQ10 supplementation. CoQ10 supplementation in a dose of 200 mg daily is associated with mild antiaggregatory changes in the hemostatic profile. Clinical beneficial effects of CoQ10 may be related in part to a diminished incidence of thrombotic complications.
