Myocardial injury after noncardiac surgery
Bibliographic record
Abstract
PURPOSE OF REVIEW: Recent investigations have substantially improved our understanding of myocardial injury after noncardiac surgery (MINS). RECENT FINDINGS: MINS is defined as a prognostically relevant myocardial injury due to ischemia that occurs during or within 30 days after noncardiac surgery. MINS occurs in 8% of adults undergoing major noncardiac surgery and is diagnosed with an elevated postoperative troponin measurement. MINS is associated with significant morbidity, and approximately 10% of patients experiencing MINS will die within 30 days. There is a dose-graded response in mortality and time to death with increasing levels of postoperative troponin elevations. Most patients (>80%) suffering from MINS will not experience an ischemic symptom. Without troponin monitoring, the majority of MINS events would go undetected. To avoid missing these prognostically relevant events, guidelines now recommend perioperative troponin monitoring in high-risk patients having noncardiac surgery. In patients who suffer MINS, risk-adjusted observational data suggest that aspirin and a statin can reduce the risk of 30-day mortality. SUMMARY: Among adults, MINS is the most common cardiovascular complication that occurs after noncardiac surgery. Given that worldwide 200 million adult patients undergo major noncardiac surgery each year, at least 8 million of these patients will suffer MINS making this a substantial public health problem.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
