The urgent diagnosis of acute pulmonary thromboembolism benefits from the use of evidence-based clinical guidelines that improve patients' prognoses and reduce the unnecessary use of imaging tests. This article explains the diagnostic algorithms for pulmonary thromboembolism most recently published by the relevant scientific societies both for the general population and for special situations, trying to clear up common doubts and analyzing persistent controversies. It also discusses the need to follow up the thromboembolism after anticoagulation treatment, which is not currently recommended in the guidelines.
