夏说英语新闻晨读 第560期:毋需老方子预防心脏病啦

 If you're a healthy older adult looking for ways to reduce your risk of heart attack and stroke, don't turn to that age-old standby: daily low-dose aspirin¹. It's no longer recommended as a preventative for older adults who don't have a high risk or existing heart disease, according to guidelines announced Sunday by the American College of Cardiology and the American Heart Association. However, for anyone who has had a stroke, heart attack, open-heart surgery or stents inserted to open clogged² arteries³, aspirin can be life-saving.
