Your blood group could increase your chance of having a heart attack or stroke
研究：非O型血的人患心脏病的风险更高
Almost half (48 per cent) of people in the UK have O blood. But according to an analysis of studies involving 1.3million people, those who have A, B and AB blood have a slightly higher risk of heart disease and stroke.
英国有近一半(48%)的人是O型血。但根据对130万人的研究分析，A，B，AB型血的人心脏疾病和中风的风险略高。
Scientists think it could be because of higher levels of a blood-clotting protein in those blood groups.
科学家认为这可能是因为这些血型中凝血蛋白水平较高。
Study author Tessa Kole, of the University Medical Center Groningen in the Netherlands, said blood group should be considered in the future as part of risk assessment in preventing cardiovascular disease.
荷兰格罗宁根大学医学中心的研究人员Tessa Kole表示，将来应考虑将血型视为预防心血管疾病风险评估的一部分。
Of those with blood group O, 14 in 1,000 people suffered a heart attack. For non-O blood groups, the figure was 15.
在1000名O型血的人中14人有心脏病发作史。对于非O型血的人，该数字为15。
While the increased risk is small on an individual level, it could be important in terms of the population.
虽然个人水平的风险增加很小，但在人口方面却可能很重要。
Charities say the most important thing to avoid heart disease is to eat healthily, stop smoking and take exercise.
慈善机构说，避免心脏病最重要的是要健康饮食，戒烟，锻炼身体。
Dr Mike Knapton, associate medical director at the British Heart Foundation, told the BBC: "Most of a person’s risk estimation is determined by age, genetics (family history and ethnicity) and other modifiable risk factors including diet, weight, level of physical activity, smoking, blood pressure, cholesterol and diabetes.
英国心脏基金会副医学主任Mike Knapton博士向BBC表示：“大多数人的风险估计是由年龄，遗传因素(家族史和种族)以及其他可修改的风险因素决定的，包括饮食，体重，身体活动水平，吸烟，血压，胆固醇和糖尿病。"
"People with a non-O blood group type - AO, BO and AB - need to take the same steps as anyone wanting to reduce their CVD risk." The research was presented at the European Society of Cardiology.
“非O型血型的AO，BO和AB型血人， 需要采取的与其他任何人一样的步骤来降低患心血管疾病的风险。”该研究被提交在欧洲心脏病学会上。
