That's why we work up these patients. And, in most cases, it isn't even close to cheaper. The vast majority of patients admitted for ACS are discharged from the hospital with a non-ACS diagnosis. Often after nuclear stress testing and cath. The last time I looked, the 'true positive' rate for ACS patients admitted from the ED is about 15%. It is incredibly expensive to admit that other 85%. But, since missed MI cases account for the largest malpractice payouts in emergency medicine, there aren't many of us willing to go out on a diagnostic limb.
Unfortunately, we don't have a tool that will allow us to reliably distinguish between the 15% that have the disease and the 85% that don't.
Take care,

Jeff, good thoughts. I respectfulyl disagree with a few things, though.
If you've got lots of patients being discharged with a non-ACS diagnosis after a cath, you've got a trigger-happy cardiology department. I would say of the people we send to cath, maybe 1 in 10 comes back clean. Sure, some are less than 70% stenosed and don't get intervention but their chest pain is quite likely cardiac anyway. If a good clinician risk-stratifies a patients and gives him a good work-up, the negative cath is pretty rare.
And I don't think that the admit-to-rule-out-and-do-a-cardiolyte-in-the-morning is a bad thing. Sure, it's 2000 bucks out the window right now but then you've got your claws in a guy you can talk to about statins and merformin and seeing a dietician. You tell someone about these things when they have their butt hanging out from a patient gown, you've got a captive audience. That's where you might save some money in the long run. And, trust me, I have bitched and moaned about CP admits, but don't forget they come in because they have been told by us that "any pain can be a sign of a heart attack, especially if you are a woman".
All this will change, of course, in 5 years. Our institution just bought a 128-slice CT scanner for cardiac angiography. Oh, yeah
. This will essentially mean the end of low-risk CP admits.
At some point, the resolution will be so good that people will get screened and receive a cardiac risk staging (30% narrowing can be stable as hell or just about to pop; something we can't tell from a cath today). This will give EPs a helping hand in telling who can go home and who stays.
Wow, talk about going off on a tangent. I just happen to like this topic.
Oh yeah, I agree with KentW. An internist or FP should do the same tests and admit by the same standards as an EP. In my experience, internists get very easily freaked out by ongoing chest pain and very often admit patients.
