Major Surgery, Silent Threat: Myocardial Injury’s Hidden Impact

In a global study of 22,552 major general surgery patients, 16.3% experienced myocardial injury after noncardiac surgery (MINS). Shockingly, 89.9% of MINS cases showed no symptoms, emphasizing the hidden danger. Those with MINS faced a nearly 5-fold increase in 30-day mortality (6.8% vs. 1.2%), underlining its prognostic importance. This exposes the need for routine postoperative troponin monitoring to unveil asymptomatic MINS, potentially saving lives after major surgery.
