NBC晚间新闻 阿司匹林新发现颠覆过往认知（在线收听）

It's long-standing advice followed by millions of Americans, an aspirin a day can prevent a first heart attack. But now a major about-face, new guidelines from the American Heart Association now say adults over 70 should not be taking the drug. Aspirin isn't harmless. The new recommendation comes after three large studies found that aspirin did not prevent heart attacks and strokes in older adults. In fact, taking it every day raised the risk of serious harm like stomach and brain bleeding.

Those who should not take aspirin include people over 70, anyone who does not have heart disease, anyone at risk for bleeding. For someone who's taking aspirin right now, what should they do? People are taking aspirin should not just stop. They should have a conversation with a physician and really determined their individual risk versus benefit. Dr. Torres joins us now. Who should still be on aspirin? So people who have already had a heart attack or stroke, for them a daily aspirin can be life-saving. People who are at a high risk of their first heart attack or stroke should consider the pros and cons of taking aspirin with their doctor though before they start taking. All right, Dr. Torres thank you.

每天吃一片阿斯匹林可以预防第一次心脏病发作，这是数百万美国人长久以来遵循的建议。但是现在情况有了重大转变，据美国心脏学会的新指南称，年龄超过70的成年人就不应该服用阿司匹林。阿司匹林并非没有伤害。在三项大型研究发现阿司匹林不能预防老年人心脏病和中风发作后，美国心脏学会提出了上述建议。实际上，每日服用阿司匹林会提升胃出血和脑出血等严重伤害的风险。不应该服用阿司匹林的人包括：年龄超过70的人，没有心脏病的人，以及有出血风险的人。对于现在正在服用阿司匹林的人来说，他们应该怎么办？正在服用阿司匹林的人不应该就此停止服用。他们应该咨询医生，判断个人服药的风险和益处。托雷斯医生来到了演播室。什么人应该继续服用阿司匹林呢？对于那些已经有过心脏病或中风发作的人来说，每天服用阿司匹林可以拯救生命。对于那些有首次心脏病和中风发作的高风险人群来说，在服用阿司匹林前，他们应与医生一同考虑服药的害处和益处。好的，谢谢您托马斯医生。
