Differential Diagnosis for Sharp Chest Pain with Shortness of Breath

Immediate Life-Threatening Causes

• The American College of Cardiology recommends that sharp chest pain does not exclude acute coronary syndrome (ACS), particularly in patients with cardiovascular risk factors 1, 2
• The American Heart Association suggests obtaining an ECG within 10 minutes of presentation and measuring cardiac troponin immediately to diagnose ACS 1, 2
• ACS can present with atypical features, including sharp or stabbing pain, especially in diabetics, women, and elderly patients, according to the American College of Cardiology 1, 2
• The European Society of Cardiology states that associated symptoms suggesting ACS include dyspnea, diaphoresis, nausea, lightheadedness, or upper abdominal discomfort 1, 2
• At age 49, this patient is in the high-risk demographic for coronary disease, as indicated by the European Heart Journal 3, 1
• The American College of Cardiology recommends considering pulmonary embolism (PE) as a critical cause of sharp chest pain with shortness of breath, characterized by the classic triad of dyspnea, tachycardia, and pleuritic chest pain 2
• Sharp pain that worsens with inspiration is characteristic of PE, according to the European Heart Journal 4, 2
• The American Heart Association suggests looking for risk factors for PE, such as recent immobilization, surgery, malignancy, or prior DVT 5
• Aortic dissection is a life-threatening cause of sharp chest pain, characterized by sudden-onset "ripping" or "tearing" pain radiating to the back, as described by the American College of Cardiology 1, 2
• The American Heart Association recommends checking for pulse differentials between extremities and blood pressure differences between arms to diagnose aortic dissection 2
• Pneumothorax is a life-threatening cause of sharp chest pain, characterized by sharp, pleuritic chest pain with sudden onset, according to the American College of Chest Physicians 2

Cardiac Causes

• The American College of Cardiology states that acute pericarditis is characterized by sharp chest pain that increases with inspiration and lying supine, and improves when sitting forward 1, 2
• The American Heart Association recommends listening for pericardial friction rub on examination to diagnose acute pericarditis 2
• Esophageal disorders, such as esophageal spasm, can mimic cardiac pain and respond to nitroglycerin, as indicated by the American College of Cardiology 1

Pulmonary Causes

• The European Respiratory Society states that pleuritis/pleurisy is characterized by sharp, localized chest pain worsening with deep breathing or coughing, and may be associated with pneumonia, viral infection, or autoimmune conditions 4
• Pneumonia is a pulmonary cause of sharp chest pain, characterized by pleuritic chest pain with dyspnea, fever, and productive cough, according to the American Thoracic Society 4

Diagnostic Algorithm

• The American College of Cardiology recommends obtaining an ECG within 10 minutes of presentation to diagnose ACS 1, 2
• The American Heart Association suggests measuring cardiac troponin as soon as possible to diagnose ACS, even with sharp pain 2
• A focused cardiovascular examination, including checking vital signs and auscultating for decreased breath sounds, is essential for diagnosing life-threatening causes, as recommended by the American Heart Association 2
• The American College of Cardiology recommends assessing pain characteristics systematically, including nature, onset, radiation, precipitating factors, and associated symptoms, to diagnose life-threatening causes 1, 2
• Risk stratification, including assessing age, hypertension, diabetes, smoking, and family history, is essential for diagnosing CAD, as indicated by the American College of Cardiology 1, 2
