Overview
Pulmonary embolism must be distinguished from other life-threatening causes of chest pain including acute myocardial infarction, aortic dissection, and pericardial tamponade, as well as a large list of non-life-threatening causes of chest discomfort and shortness of breath.
Differential Diagnosis
Differential Diagnosis Based on Symptoms
Pulmonary embolism (PE) should be differentiated from other diseases presenting with chest pain, shortness of breath and tachypnea. The differentials include the following:[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]
| Diseases | Diagnostic tests | Physical Examination | Symptoms | Past medical history | Other Findings | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| CT scan and MRI | EKG | Chest X-ray | Tachypnea | Tachycardia | Fever | Chest Pain | Hemoptysis | Dyspnea on Exertion | Wheezing | Chest Tenderness | Nasalopharyngeal Ulceration | Carotid Bruit | |||

Life Threatening Differential Diagnosis
Common Differential Diagnosis in Outpatients
Among outpatients presenting with dyspnea, <4 % are diagnosed with PE.[21] Common differential diagnoses include:[21]
