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!). Now there's evidence also that cardiac risk factors are ineffective at predicting in-hospital mortality in patients that rule in for acute MI. [1]  In fact, this study actually demonstrated that in-hospital mortality is inversely related to the number of cardiac risk factors!

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.
