Introduction: High-sensitivity troponin (HS-troponin) improves the detection myocardial infarction compared to conventional troponin, though its clinical specificity remains debated. This study compared both assays in terms of elevated levels and hospital resource utilization in a high-volume urban hospital. Method: Retrospective analysis of adults seen at Lyndon B. Johnson Hospital (Houston, USA) in January (conventional troponin) and March 2024 (HS-troponin). Clinical data, troponin levels, diagnostic studies, and outcomes were collected. Results: A total of 1324 patients were analyzed in January and 1322 in March. Elevated values were more frequent with HS-troponin (20 vs. 16%; p < 0.001), without a proportional increase in consultations, testing, or acute coronary syndrome (ACS) diagnoses (2 vs. 7%). In-hospital mortality was lower in the HS-troponin group. Conclusions: HS-troponin detects more elevated values without increasing resource use or ACS diagnoses. Its clinical value, however, requires more refined application criteria.
