Title: coronary risk factors and AMI mortality
题目：冠心病危险因素与急性心肌梗塞死亡率
Author 作者: Amal Mattu

We've noted studies in recent years indicating that cardiac risk factors are ineffective at predicting the likelihood of ACS in patients with acute chest pain (in other words, it's all about the HPI and EKG!).
最近几年我们已经了解，冠心病危险因素并不能有效地预测急性心绞痛病人发生急性冠状动脉综合症的可能性（换句话说，主要依赖于现病史和心电图）。
Now there's evidence also that cardiac risk factors are ineffective at predicting in-hospital mortality in patients that rule in for acute MI.
现在又有证据证实，并不能有效地预测已明确诊断急性心肌梗塞病人的住院死亡率。
In fact, this study actually demonstrated that in-hospital mortality is inversely related to the number of cardiac risk factors!
实际上，这个研究证实住院死亡率与冠心病危险因素成反比。
The bottom line is simple: cardiac risk factors are useful at predicting long-term risk for development of coronary artery disease, but they are NOT useful at in the acute setting.
最后的要点是非常简单的：冠心病危险因素在判断发生冠状动脉疾病长期危险方面是有用的，但在急性情况下的意义不大。
