Answer

Serum troponin levels can be elevated in up to 50% of patients with a moderate to large pulmonary embolism, presumptively due to acute right ventricular myocardial stretch. [50]

Although troponin assessment is not currently recommended as part of the diagnostic workup, studies have shown that elevated troponin levels in the setting of pulmonary embolism correlate with increased mortality. [54] However, further studies need to be performed to identify subsets of patients with pulmonary embolism who might benefit from this testing.
