摘要
BackgroundAtherosclerotic 匾显示局部缺血事件和它的出现是为临床的医生的一项困难的任务。葡萄种子 proanthocyanidin 摘录(GSPE ) 被报导了由在动物导致动脉粥样硬化患者匾的回归施加 antiatherogenic 效果试验性的研究。在这研究， GSPE 的 antiatherogenic 效果在 287 个病人与免费颈动脉 intima 媒介厚度(CIMT ) 随机被分到 GSPE 组的无征状的颈动脉匾或反常的匾诊断了的临床的 use.MethodsConsecutive 被调查了(n = 146 ) 或控制组(n = 141 ) 。在 GSPE 的病人口头上地每天组织收到的 GSPE 200 mg，当在控制组的病人仅仅在一个生活方式干预程序被注册时。颈动脉超声检查在基线被执行并且 6， 12， 24 个月在后续期间。吝啬的最大的 CIMT ( MMCIMT )，匾分数，脉管的事件是的匾和 ischemic 的 echogenicity recorded.ResultsAs 预计在治疗以后， GSPE 在 MMCIMT 前进导致了重要减小(在六个月以后的4.2%减少，4.9%在 12 个月以后减少，5.8%在 24 个月以后减少)并且为主要结果的匾分数(在六个月，在 12 个月以后的24.1%减少和在 24 个月以后的33.1%减少以后的10.9%减少)，当 MMCIMT 和匾分数稳定、平时，增加匾和不稳定的匾的数字也在 GSPE 的治疗以后减少了。而且，颈动脉匾能与 GSPE 消失在治疗以后。为在 GSPE 组的不稳定的咽峡炎的为临时的 ischemic 攻击( TIA )的发生率，动脉的 revascularization 过程，和医院重新接纳是统计上重要的更低( P = 0.02 ， 0.08 ， 0.002 ，分别地)与控制相比， group.ConclusionsGSPE 禁止了前进在 GSPE 的 MMCIMT 和减少的颈动脉匾尺寸对待病人，并且与扩大治疗， MMCIMT 上的优异功效和颈动脉匾发生了。而且， GSPE 组显示出临床的脉管的事件的更低的率。
Background Atherosclerotic plaques indicate the occurrence of ischemia events and it is a difficult task for clinical physicians. Grape seed proanthocyanidin extract （GSPE） has been reported to exert an antiatherogenic effect by inducing regression of atherosclerotic plaques in animal experimental studies. In this study, the antiatherogenic effect of GSPE has been investigated in clinical use. Methods Consecu- tive 287 patients diagnosed with asymptomatic carotid plaques or abnormal plaque free carotid intima-media thickness （CIMT） were ran- domly assigned to the GSPE group （n = 146） or control group （n = 141）. The patients in the GSPE group received GSPE 200 mg per day orally, while patients in the control group were only enrolled in a lifestyle intervention program. Carotid ultrasound examination was per- formed at baseline and 6, 12, 24 months during follow-up. Mean maximum CIMT （MMCIMT）, plaque score, echogenicity of plaques and ischemic vascular events were recorded. Results As anticipated, after treatment, GSPE resulted in significant reduction in MMCIMT pro- gression （4.2% decrease after six months, 4.9% decrease after 12 months and 5.8% decrease after 24 months） and plaque score （10.9% de- crease after six months, 24.1% decrease after 12 months and 33.1% decrease after 24 months） for the primary outcome, while MMCIMT and plaque score were stable and even increased with the time going on in control group. The number of plaques and unstable plaques also de- creased after treatment of GSPE. Furthermore, the carotid plaque can disappear after treatment with GSPE. The incidence rate for transitory ischemic attack （TIA）, arterial revascularization procedure, and hospital readmission for unstable angina in GSPE group were statistically significant lower （P = 0.02, 0.08, 0.002, respectively） compared with the control group. Conclusions GSPE inhibited the progression of MMCIMT and reduced carotid plaque size in GSPE treated patients, and with extended treatment, the superior efficacy on MMCIMT and carotid plaque occurred. Furthermore, the GSPE group showed lower rates of clinical vascular events.
