Overview

A proper history and physical exam is crucial to establish an accurate diagnosis of pulmonary embolism (PE). The symptoms of pulmonary embolism (PE) depend on the severity of the disease, ranging from mild dyspnea, chest pain, and cough, to sustained hypotension and shock.[1][2] A PE may also be an incidental finding in so far as many patients are asymptomatic.[2][3] Sudden death can be the initial presentation of PE. One of the first steps in the management of PE is the determination of the Wells score for PE, whose criteria can be ascertained solely on the basis of history and physical exam. Symptoms of DVT of the lower extremity may be present.

History and Symptoms

As depicted in the image below, the majority of patients with venous thromboembolism (VTE), that is DVT, PE, or both, are asymptomatic.

The challenge in diagnosis of VTE

Symptoms of PE

The Prospective Investigation Of Pulmonary Embolism Diagnosis II (PIOPED II) study identified the triad of symptoms, dyspnea, chest pain, and tachypnea, present in a majority of patients with a confirmed pulmonary embolism.[1][4] Symptoms of PE include:

Symptoms of DVT

Since VTE involves both DVT and PE, the patient can present with complaints of either of the diseases. Therefore it is important to inquire about the symptoms of both diseases.

Common Symptoms of DVT

The classical symptoms of DVT include:

However, sometimes there may be no symptoms referable to the location of the DVT.

Less Common Symptoms of DVT

Complete History

If VTE is suspected or diagnosed, a complete history should be elicited, including the following:
