美国的一项研究表明,假期的欢乐聚会可能会引起致命的心脏病发作。研究者们很早以前就知道心脏病在清晨发作的危险性比其他时候多得多,因为血液在那时易于凝结。这种血液凝块如果阻塞了心脏的动脉,那就可以诱发心脏病的发作。当前的研究表明,节假日恰恰是心脏病致死的高发时期。洛杉矶南加州大学的学者罗伯 A study in the United States shows that a holiday party can cause a fatal heart attack. Researchers had long ago realized that heart attacks are much more dangerous in the early morning than any other time since blood clotted easily at that time. If this blood clot blocked the heart’s arteries, it could trigger a heart attack. The current study shows that holidays are precisely the high incidence of heart death.
