Key result
Postoperative troponin elevation occurs in 5% to 25% of noncardiac surgery patients and is strongly associated with increased short-term and long-term mortality and major adverse cardiac events.
Troponin elevation after noncardiac surgery is common and carries a worse prognosis, highlighting the need for tailored medical management and ongoing clinical trials to establish definitive treatment strategies.
Postoperative troponin elevation flags higher short- and long-term risk after noncardiac surgery; leaves optimal management open pending prospective trials.
How to interpret and manage troponin elevations after noncardiac surgery is a common clinical question for cardiologists and internists. An estimated 5% to 25% of patients who undergo noncardiac surgery have an elevated postoperative troponin level. Patients with troponin elevation are at higher short-term and long-term risk of morbidity and mortality. Current guidelines provide few recommendations on how to manage these patients. The authors review the evidence and guidelines and propose treatment strategies.

Horr et al. (2015) conducted a review in Troponin elevation after noncardiac surgery. Troponin elevation vs. Normal troponin levels was evaluated. Postoperative troponin elevation occurs in 5% to 25% of noncardiac surgery patients and is strongly associated with increased short-term and long-term mortality and major adverse cardiac events.
