PE can mimic ACS; which diagnostic test supports the diagnosis of PE?

PE can present with chest pain and shortness of breath much like ACS, so we need a test that directly confirms an embolus in the lungs. CT pulmonary angiography is the imaging test that visualizes clots within the pulmonary arteries, providing direct and reliable evidence of PE with high sensitivity and specificity. It also helps assess the extent of embolism and potential hemodynamic impact. Other tests—like echocardiography—may show signs of right‑sided strain if PE is causing instability but don’t prove the presence of a clot. Serum troponin and ECG changes can reflect strain or myocardial injury but are not diagnostic for PE. If CT isn’t an option, alternative tests exist, but CT pulmonary angiography remains the best confirmatory test in most stable patients.
