The Lancet:血型与心脏病的发作之间关联很大 O型酶护心脏
来源:《糖尿病之友》 2011-04-01 16:54
O型血者是危险的万能供血者。据国外媒体最新报道,1月15日出版的《柳叶刀》杂志刊登一项新研究发现,O型血者较少罹患心脏病。
美国宾夕法尼亚大学心血管研究中心科学家比较了13000名冠心病患者与7400名非冠心病患者。为了研究特殊基因对心脏病的作用,研究人员比较了5800名发作过心脏病的冠心病患者和3600名未发作过心脏病的冠心病患者。结果发现,一个编号为ADAMTS7的基因与冠心病危险增加关联密切。同时还发现,血型与心脏病发作之间关联很大。
研究人员指出,O型血者体内有一种基因可产生一种酶,从而使其血液呈现O型。正是这种基因对一些O型血患者起到保护作用,降低其心脏病发病率。新研究负责人穆雷达奇·P·雷利博士表示,新研究表明,血型与心血管疾病存在多层面的关联,如与血栓形成及冠心病发病几率关系密切等。(生物谷Bioon.com)

Summary
Background
We tested whether genetic factors distinctly contribute to either development of coronary atherosclerosis or, specifically, to myocardial infarction in existing coronary atherosclerosis.
Methods
We did two genome-wide association studies (GWAS) with coronary angiographic phenotyping in participants of European ancestry. To identify loci that predispose to angiographic coronary artery disease (CAD), we compared individuals who had this disorder (n=12 393) with those who did not (controls, n=7383). To identify loci that predispose to myocardial infarction, we compared patients who had angiographic CAD and myocardial infarction (n=5783) with those who had angiographic CAD but no myocardial infarction (n=3644).
Findings
In the comparison of patients with angiographic CAD versus controls, we identified a novel locus, ADAMTS7 (p=4·98×10?13). In the comparison of patients with angiographic CAD who had myocardial infarction versus those with angiographic CAD but no myocardial infarction, we identified a novel association at the ABO locus (p=7·62×10?9). The ABO association was attributable to the glycotransferase-deficient enzyme that encodes the ABO blood group O phenotype previously proposed to protect against myocardial infarction.
Interpretation
Our findings indicate that specific genetic predispositions promote the development of coronary atherosclerosis whereas others lead to myocardial infarction in the presence of coronary atherosclerosis. The relation to specific CAD phenotypes might modify how novel loci are applied in personalised risk assessment and used in the development of novel therapies for CAD.
Funding
The PennCath and MedStar studies were supported by the Cardiovascular Institute of the University of Pennsylvania, by the MedStar Health Research Institute at Washington Hospital Center and by a research grant from GlaxoSmithKline. The funding and support for the other cohorts contributing to the paper are described in the webappendix.

ATVB:血型会影响心脏病患病风险
译文来源:生物谷 2012-08-15 11:30
2012年8月15日 讯 /生物谷BIOON/ --与O型血的人相比,A,B或AB型血的人患冠状动脉心脏疾病的风险较高,根据发表在Arteriosclerosis, Thrombosis and Vascular Biology杂志上的一项最新研究证实。在研究这种稀有血型AB型的人过程中,这类血型的人占美国总人口的约7%,研究者发现这些AB型的人患心脏疾病的风险最高增加了23%。B型血的人患病风险增加了11%,A型血的人有5%的增加。
营养学系助理教授Lu Qi医学博士,研究的资深作者说:虽然人们无法改变自己的血型,我们的研究结果可以帮助医生更好地了解哪些人易患心脏疾病。Qi说,知道自己的血型对于保持健康,避免心脏疾病是非常重要的。与了解你的血型类似,你应该知道你的胆固醇或血压数,如果你知道你存在更高的患病风险,那么你可以采取健康的生活方式如饮食、运动和不吸烟来减少风险。
这一发现是基于两个大型的美国著名的研究分析,护士健康研究Nurses' Health Study中的62073妇女和Health Professionals Follow-up Study中的27428成人。参与者在30岁和75岁之间,两组分别追访研究了20年或更长时间。研究人员还考虑研究对象的饮食、年龄、身体质量指数、性别、种族、吸烟状态、绝经状态和病史。有证据表明A型血与低密度脂蛋白胆固醇水平较高有关,AB型与炎症相关。此外,血液流量和促进凝血的物质在O型血的人中可能会更高。
了解血型可以帮助更好地调整医疗服务提供治疗。例如A型血的病人要想降低心脏疾病的风险,应减少胆固醇的摄入量。研究参试者主要是白人,现在还不清楚这些研究结果是否会也适用其他族群。国家卫生研究院、美国心脏协会科学家发展奖和波士顿肥胖营养研究中心资助该项研究。(生物谷:Bioon.com)
