Pleuritic Chest Pain: Causes, Approach, and Management
Definition and Key Characteristics
- Pleuritic chest pain is sharp, stabbing, or "knifelike" pain that worsens with deep breathing, coughing, or respiratory movements, and is caused by inflammation or irritation of the pleura 1
- The pain is typically localized and may be described as burning or stabbing in quality 1
- Distinguished from anginal pain, which presents as pressure or heaviness rather than sharp stabbing 1
- Pain reproducible with chest wall palpation suggests musculoskeletal origin, but 7% of patients with reproducible tenderness still have acute coronary syndrome 2
Life-Threatening Causes
- Pulmonary embolism presents with dyspnea, pleuritic pain, tachycardia (>90% of cases), and tachypnea 2
- Pleural effusion develops in 46% of PE cases and is frequently hemorrhagic 1
- Central PE may present with retrosternal angina-like pain reflecting right ventricular ischemia 1
- Acute coronary syndrome: 13% of patients with pleuritic pain have acute myocardial ischemia 1, 2
- Atypical presentations including pleuritic pain are more common in elderly, women, diabetics, and those with renal insufficiency 3
- Sharp, pleuritic features do not exclude cardiac ischemia 2
Diagnostic Approach
- ECG within 10 minutes of arrival to identify STEMI, pericarditis patterns, or signs of PE 2
- Chest X-ray to evaluate for pneumothorax, pneumonia, pleural effusion, or widened mediastinum 2, 5
- Cardiac troponin measured as soon as possible to exclude myocardial injury 2
- Vital signs assessment: tachycardia and tachypnea present in >90% of PE cases 2
- Use validated clinical decision rules to determine pretest probability for pulmonary embolism 2
- D-dimer testing with age- and sex-specific cutoffs for low-to-intermediate pretest probability patients 2
- CTA with PE protocol for stable patients with high clinical suspicion 2
Physical Examination Pearls
- Pleural friction rub: biphasic, coarse, grating sound heard during both inspiration and expiration, not cleared by coughing, indicates pleural inflammation 1
- Pericardial friction rub suggests pericarditis 3
- Unilateral decreased breath sounds suggest pneumothorax or large pleural effusion 2
- Pulsus paradoxus may indicate cardiac tamponade 3
Critical Pitfalls to Avoid
- Never assume reproducible chest wall tenderness excludes serious pathology (7% have ACS) 2
- Nitroglycerin response should not be used as diagnostic criterion - relief does not confirm or exclude myocardial ischemia 2
- Do not delay transfer for troponin testing in office settings - patients with suspected ACS should be transported urgently to ED by EMS 2
- Sharp, pleuritic pain does not exclude cardiac ischemia 2
