Study: Flu Vaccine¹ Could Prevent Heart Attack 研究表明流感疫苗能预防心脏病

The flu season is just beginning in the northern hemisphere and doctors are urging anyone older than six months to get immunized. A new study also suggests the vaccine may do more than ward² off the flu.Medical experts say there is nothing that kills as many people as the flu.

北半球的流感季节刚刚开始,医生们就开始督促六个月以上的儿童和成人注射流感疫苗.一项最新研究也表明疫苗除了能预防`流感,还有其它益处.医学专家表示流感所造成的死亡人数最大的因素。

Heart patients, like Loreen Naylor, are especially vulnerable. That's why she gets vaccinated³ every year. "I think it is very important. It’s a way of managing my own health and making sure I don’t get the flu,” she said.

像Loreen Naylor这类患有心脏病的群体更容易染上流感.这也是她为什么每年都注射流感疫苗的原因.Loreen说:“我觉得注射疫苗是很重要的事.这是保持健康的一种方式,能也确保自己不会得流感。”

Doctors say heart patients who get the flu seem to have a higher risk of heart attack, heart failure or stroke.

医生也表示心脏病人一旦染上流感，他们心脏病发，心脏衰竭，中风的可能性就更高。

Researchers believe as our bodies fight the disease, inflammation and plaque⁴ in our arteries⁵ become more unstable⁶ and may form clots⁷ and blockages⁸. It appears the flu vaccine, though, may help protect even healthy people from heart attack and stroke.

研究人员认为，当我们的身体在对抗疾病时，我们动脉中的炎症和血小板会变的不稳定，可能会产生血块，造成血流堵塞。流感疫苗可能会有助于人们预防心脏病发作，降低中风风险。

Dr. Jacob Udell at Women's College Hospital in Toronto analyzed⁹ data from previous studies involving nearly 7,000 patients.  

多伦多女子学院医院的 Jacob Udel博士分析了近7000名患者的数据资料。

“Overall there was about a 33 percent reduction in risk for heart attacks, strokes and other major cardiovascular events in those who received the flu shot, compared to those who’d received a placebo¹⁰ or just the standard of care,” said Udell.

他表示：“整体来讲，与那些只是注射了安慰剂或者仅是接受标准护理的人相比，注射了疫苗的人，心脏病发作，得中风，或其它主要心血管疾病的风险下降了大33％”

For people who'd recently had a heart attack, getting a flu shot cut their risk of having another one by 50 percent. So Dr. Udell says getting the vaccine is a no brainer [requires little thought].

对于刚刚心脏病发作过的人来讲，注射流感疫苗会使其心脏病再次发作的风险减少50％。因此，Udell表示注射疫苗是件不必动脑的事。

"I encourage anybody who’s skeptical¹¹ about getting the flu vaccine for any reason that there is a potential other benefit here from a cardiac point of view,” he said.

他说：“对那些对流感疫苗持怀疑态度的人，无论是什么原因，我都要对其进行劝说，因为从一名心脏病者的角度来讲注射流感疫苗还有其它潜在的益处。”

Udell said he now wants to hold a large new trial to see if he gets the same outcome. The result of his recent analysis was published in the Journal of the American Medical Association.

Udell表示他现在想实施一项新的大规模的实验，看是否会得到同样的结果。这项研究结果发表在《美国医学协会杂志》上。
