Troponin levels

  1. 0
    Regarding troponin levels...

    Does the higher the troponin level = more cardiac damage and poorer prognois? Or after a certain level, it's all considered extensive damage?

    I'm a fairly new nurse, and I don't work on a cardiac floor. So most of my patients get cardiac enzymes to rule out MI's. Mostly they come back negative or slightly elevated. Reason I'm asking is that someone in my family with CHF and loads of cardiac and other health issues just had an MI while in the hospital for CHF exacerbation, and the troponin level was 40. that's quite elevated--but I haven't seen enough elevated troponin levels to know if that's wildly elevated, or a value that's seen often enough with MI's....

    I'd appreciate any info, I've tried to research it in my books and on the internet, but I can't get any specific info.

    Was the result 40 or 4.0 ?? I'm not a cardiac nurse ,but in our facility anything > 0.1 is considered elevated. Either way that's HIGH.

    His nurse had said 40... I never have seen a level that high. Perhaps she had mispoke...but I definitely heard 40. I guess that's why I'm posting this...'cause I've not seen one that high before and wondering if that's possible.

    I just asked our clinical co-ordinator - the higher the level the greater the degree of infarction. Regarding outcome: it depends on where the damage is, what kind of collateral circulation the patient has, general condition, type and speed of treatment etc.
    I haven't seen many levels over the mid-40 mark, but she said that some patients have come in with troponin levels over 500 (on the off-chance that there's a difference in US/Australian unts of measure, significant is >0.3).
    I hope this helps

    A level of 40 would signify a significant MI or other cardiac event. I've seen tropis over 300 a few times. These were after MIs with multiple vessels involved = multiple areas of damage.

    I've never seen a trop in the hundreds--hard to imagine what their quality of life would be after an event like that --but in the 40s, yes.

    I consider that pretty high.

    Thank you for your replies. I didn't know levels could get in the hundreds! It would make sense the higher the value = more damage. I appreciate your time and information.

    Actually, these people survived after immediate intervention with multiple stents and, in some cases, IABP for a few days.

    That's why I love this job. We literally bring people back from the dead. It's just so amazing to work this unit, isn't it?
