Optimizing Use of High-Sensitivity Troponin for Risk-Stratification of Acute Pulmonary Embolism.

 In this retrospective, single-center study of acute PE patients, we identified distinct optimal HS-TnT values for different clinical uses-a lower cutoff, which identified low-risk patients even in the absence of other risk-stratification methods, and a higher cutoff, which was strongly associated with adverse outcomes in patients at increased risk.
