一半的心脏健康可以掌握在自己手里

一半的心脏健康可以掌握在自己手里
健康的生活方式比遗传因素更重要

       据新英格兰医学杂志2016年11月13日的网上首发报告，一项包括5.5万人的4个独立研究表明，尽管遗传和生活方式都可能影响心脏病的发生，但两因素是相对独立的。也就是说，不管你从父母哪遗传到多大患心脏病的风险，只要努力保持健康习惯，都会减少心脏病的风险。
       数据表明，通过不吸烟、中度锻炼、及多吃水果、青菜和谷物等健康食品，可以搞定（tamp down）最危险的遗传因素，降低心脏病风险达50％。

       这个重要的信息为所有人预防“第一杀手”带来了希望，也告诉我们至少50％的心脏健康可以掌握在自己手里，如果大家都做到了，一半的心脏科医生会丢掉工作。 （作者：李永明）

Healthy Lifestyle May Reduce Heart Risks Regardless Of Genetics, Research Suggests

The New York Times (11/13, A19, Kolata, Subscription Publication) reports that research suggests that “genetics” may not be “destiny when it comes to heart disease.” Investigators looked at data on approximately 55,000 people. The researchers found that “by living right – by not smoking, by exercising moderately and by eating a healthy diet heavy in fruits, vegetables and grains – people can tamp down even the worst genetic risk.” The findings were published in the New England Journal of Medicine.

Conclusion: Across four studies involving 55,685 participants, genetic and lifestyle factors were independently associated with susceptibility to coronary artery disease. Among participants at high genetic risk, a favorable lifestyle was associated with a nearly 50% lower relative risk of coronary artery disease than was an unfavorable lifestyle.
