Overview
Pulmonary embolism is frequently asymptomatic. Prospective Investigation Of Pulmonary Embolism Diagnosis Study (PIOPED) found the following symptoms in 97% of patients with angiographic proven PE[1].
The absence of this triad reduces the clinical probability of PE. Symptoms or signs of lower extremity deep venous thrombosis (DVT) can also be present in the patient.
History & Symptoms
Three major clinical presentations:
- Dyspnea with or without pleuritic chest pain and hemoptysis
- Hemodynamic instability and syncope (associated with massive pulmonary embolism)
- In the elderly, it may mimick as indolent pneumonia or heart failure.
Thus, the symptoms are highly variable, nonspecific, and common among patients with and without PE
