Key result
Elevated troponin I in patients with normal or mild coronary disease had no identifiable cause in 10 of 21 cases, with no deaths or myocardial infarction occurring over 41 weeks of follow-up.

Many troponin elevations with normal coronaries lack clear precipitants; leaves open refined diagnostic pathways beyond ischemia.

What are the precipitating events for troponin I elevation in patients with angiographically normal coronary arteries?
Troponin I elevation can occur without significant angiographic coronary artery disease due to various non-ischemic causes, highlighting that it is a sensitive marker of myocardial injury but not synonymous with infarction.
Bakshi et al. (2002) conducted an observational in Elevated troponin I with normal or mild coronary artery disease (n=21). Elevated troponin I without significant coronary artery disease was evaluated on Precipitating event for TnI elevation. Elevated troponin I in patients with normal or mild coronary disease had no identifiable cause in 10 of 21 cases, with no deaths or myocardial infarction occurring over 41 weeks of follow-up.
