raised troponin

[Caradomben]

Hi has anyone had a raised troponin during an attack of fast AF. mine was 36 then 83 after a recent attack which lasted 4 hours. I was told this was due to the heart getting"excited" during the attack.

Yep Sent them into a complete spin. Loads of tests no problems.

Would they always tell you? I remember my bloods being taken during fast AF and being told the results were "normal" - but I don't know if they'd consider a raised troponin level as normal in this situation, and so not bother telling the patient.

[Caradomben in reply to UScore]

I think they would have to tell you if they found something abnormal in a blood test

[UScore in reply to Caradomben]

well that's the heart (sorry) of the question. Is raised troponin during AF considered abnormal? If it's just the usual consequence of fast AF then maybe not. I literally have no idea.

Hi

This is a useful study I found online

Looks as if 68 per cent of time you can ignore!!

The positive predictive value of elevated cTnI for a coronary intervention was 26% and the negative predictive value was 68%. Using multivariate logistic regression, we found that heart rate on presentation, the presence of angina pectoris, left ventricular ejection fraction, serum creatinine, and hemoglobin independently predicted elevated cTnI level.

CONCLUSION:

These data are the first to show that AF in the acute setting is frequently associated with cTnI elevations. AF patients with high heart rate and/or angina pectoris often show false elevated cTnI levels. These findings are relevant for clinicians evaluating patients with acute AF and myocardial ischemia symptoms. Appropriate clinical guidelines must be established that also consider AF-related elevations in cTnI.

Interesting . Thank you for that

It just crossed my mind when reading this thread, is the raised troponin the cause of the AF or just an effect?

[Caradomben]

It's a cause of the AF but my GP explains it is not indicative of a heart attack .

I did, 3 days in hospital and an angiogram to be sure. The test was whether the levels went up after a certain time and as they did apparently that indicates a 'heart event'. As I was not on any anticoagulation apart from aspirin which I wouldn't take! my cardiologist was not happy......

Hi I hope you are feeling better now . I was told the same as you that it was a cardiac event but after discussion with cardiologist it was decided not. I had an exercise tolerance test and Echo which were fine . It is a worry though

[Buffafly in reply to Caradomben]

Thank you, I am fine now. I agree, it is very worrying, but as I have had a successful 'double' ablation and I'm taking Rivaroxaban regularly now I can't do much more so I try not to dwell.
