Pleuritic Chest Pain: Causes, Red Flags, and Management

Pleuritic chest pain—sharp, stabbing discomfort that worsens with inspiration—demands immediate exclusion of life-threatening conditions (pulmonary embolism, pneumothorax, acute coronary syndrome, aortic dissection, and pericarditis) before considering benign diagnoses such as viral pleurisy or costochondritis.

Life-Threatening Causes Requiring Urgent Exclusion

Pulmonary Embolism (PE)

  • PE is the most common serious cause of pleuritic chest pain, accounting for 5–21% of emergency department presentations with this symptom. 1
  • Tachycardia occurs in >90% of PE patients, and tachypnea (>20 breaths/min) in approximately 70%. 2, 3
  • Dyspnea combined with pleuritic chest pain is the hallmark presentation; pleuritic pain alone is present in 52% of confirmed PE cases. 2
  • Apply the Wells score or revised Geneva score to estimate pre-test probability before ordering D-dimer or CT pulmonary angiography (CTPA). 4, 3
  • In low-to-intermediate probability patients, obtain age- and sex-adjusted D-dimer; a negative result effectively rules out PE. 4, 3
  • If probability is high or D-dimer is positive, proceed directly to CTPA. 4, 3
  • A pleural effusion develops in ~46% of PE cases and may contribute to ongoing pleuritic discomfort. 3

Pneumothorax

  • The classic triad—dyspnea, sharp pleuritic pain on inspiration, and unilateral absent or markedly reduced breath sounds with hyperresonant percussion—identifies pneumothorax. 4, 5, 3
  • Sudden onset in a tall, thin individual or patient with underlying lung disease strongly suggests spontaneous pneumothorax. 3

Acute Coronary Syndrome (ACS)

  • Approximately 13% of ACS patients present with pleuritic-type chest pain; sharp pain does not exclude myocardial ischemia. 4, 5, 3
  • A completely normal physical examination does not rule out uncomplicated myocardial infarction. 4, 3
  • Obtain a 12-lead ECG within 10 minutes and measure high-sensitivity cardiac troponin immediately in all patients with acute chest pain. 4, 3

Aortic Dissection

  • Sudden "ripping" or "tearing" chest or back pain that is maximal at onset characterizes aortic dissection. 4, 3
  • Pulse or systolic blood-pressure differentials >20 mm Hg between extremities occur in ~30% of patients and strongly suggest dissection. 4, 3

Pericarditis

  • Sharp, pleuritic chest pain that worsens when lying supine and improves when sitting or leaning forward is pathognomonic for pericarditis. 4, 5, 3
  • A pericardial friction rub may be audible (its absence does not exclude disease), and fever commonly accompanies the presentation. 4, 5, 3
  • ECG typically shows diffuse concave ST-segment elevation with PR-segment depression. 4, 5

Other Serious Pulmonary Causes

Pneumonia

  • Fever with localized pleuritic pain, productive cough, regional dullness to percussion, and egophony suggest pneumonia. 4, 5
  • Chest radiography confirms the diagnosis; in patients >50 years, smokers, or those with persistent symptoms, repeat chest X-ray at six weeks is essential to document resolution. 1

Pneumothorax (Non-Tension)

  • Dyspnea and chest pain that worsen with inspiration; unilateral absence of breath sounds and hyperresonant percussion are typical. 2, 4

Common Benign Causes

Viral Pleurisy

  • Viruses (Coxsackieviruses, respiratory syncytial virus, influenza, parainfluenza, mumps, adenovirus, cytomegalovirus, Epstein-Barr virus) are the most common causes of pleuritic chest pain after life-threatening conditions are excluded. 1
  • Diagnosis is clinical after ruling out serious pathology; treatment consists of NSAIDs for pain management. 6, 1

Costochondritis/Tietze Syndrome

  • Palpable tenderness over costochondral joints, reproducible with direct pressure and influenced by torso movement, characterizes costochondritis. 4, 5, 3
  • When cardiac causes are excluded, costochondritis accounts for ~43% of chest-pain presentations in primary-care settings. 4, 3
  • Up to 7% of patients with reproducible chest-wall tenderness still have ACS; therefore tenderness does not completely exclude serious pathology. 4, 5, 3

Immediate Diagnostic Algorithm (First 10 Minutes)

  • Obtain a 12-lead ECG within 10 minutes to identify STEMI, new ischemic changes, or pericarditis patterns (diffuse ST-elevation with PR-depression). 4, 5, 3
  • Measure high-sensitivity cardiac troponin immediately; it is the most sensitive biomarker for myocardial injury. 4, 3
  • Assess vital signs (heart rate, respiratory rate, oxygen saturation, bilateral arm blood pressures). Tachycardia and tachypnea are red flags for PE; pulse/BP differentials suggest aortic dissection. 2, 3
  • Perform focused examination for unilateral absent/decreased breath sounds (pneumothorax or large pleural effusion) and for pericardial or pleural friction rubs. 5, 3
  • Obtain PA and lateral chest radiograph to screen for pneumothorax, pneumonia, pleural effusion, or mediastinal widening. 5, 3
  • A normal chest X-ray does not exclude pulmonary embolism or other serious conditions. 5, 3

Risk Stratification for Pulmonary Embolism

  • Apply the Wells criteria or revised Geneva score to categorize pre-test probability. 4, 3
  • Key risk factors include recent immobilization, prior DVT/PE, active malignancy, recent surgery, prolonged travel, unilateral lower-limb pain or edema, and age >65 years. 3
  • In low-to-intermediate probability patients, an age- and sex-adjusted D-dimer should be obtained; a negative result effectively rules out PE. 4, 3
  • If probability is high or D-dimer is positive, proceed directly to CT pulmonary angiography (CTPA). 4, 3

Disposition and Management

  • If the ECG shows ST-elevation, new ischemic changes, or the patient exhibits hemodynamic instability, diaphoresis, dyspnea, nausea, or syncope, activate emergency medical services for immediate transport. 4, 3
  • When high clinical suspicion exists for PE, pneumothorax, or aortic dissection, do not delay transfer for additional office testing; arrange urgent EMS transport. 4, 3
  • If cardiac testing (ECG and troponin) is normal and pain is reproducible with palpation, diagnose costochondritis and treat with NSAIDs (e.g., ibuprofen 600–800 mg TID for 1–2 weeks). 3, 1
  • If pericarditis is confirmed (positional pain, friction rub, ECG changes), initiate high-dose aspirin (500 mg–1 g q6-8h) plus colchicine (0.5–0.6 mg once or twice daily for ~3 months) and arrange cardiology consultation. 4, 3
  • For viral pleurisy, prescribe NSAIDs for pain management and provide reassurance. 6, 1

Critical Pitfalls to Avoid

  • Do not dismiss ACS solely because chest pain is pleuritic or reproducible on palpation; ≈13% of patients with pleuritic pain have myocardial ischemia, and up to 7% with reproducible tenderness still have ACS. 4, 5, 3
  • Do not rely on nitroglycerin response to differentiate cardiac from non-cardiac chest pain, as esophageal spasm and other conditions may also improve. 4, 3
  • A normal physical examination does not exclude ACS; uncomplicated myocardial infarction can present with entirely normal findings. 4, 3
  • A normal chest X-ray does not exclude pulmonary embolism; continue risk stratification and appropriate imaging based on clinical probability. 5, 3
  • Do not assume that young age or female sex excludes serious pathology; women and younger patients may present with atypical symptoms. 4
