Comprehensive Guide to Chest Pain Evaluation
Understanding the potential causes of chest pain is a critical skill in medicine. This guide provides an overview of the differential diagnosis, key investigative steps, and management principles for patients presenting with chest pain.
Key Differential Diagnoses for Acute Chest Pain
A systematic approach is essential to distinguish life-threatening conditions from more benign causes. The primary goal is to rule out causes that require immediate intervention.
- Cardiovascular Emergencies: Acute Coronary Syndrome (ACS), Aortic Dissection, Pulmonary Embolism (PE), Cardiac Tamponade.
- Other Cardiovascular Causes: Pericarditis, Myocarditis, Stable Angina.
- Gastrointestinal Causes: Gastroesophageal Reflux Disease (GERD), Esophageal Spasm, Peptic Ulcer Disease, Biliary Colic.
- Pulmonary Causes: Pneumonia, Pneumothorax, Pleuritis.
- Musculoskeletal Causes: Costochondritis, Rib Fracture, Muscle Strain.
- Psychogenic Causes: Panic Attack, Anxiety Disorders.
Initial Assessment and Investigations
The initial workup for a patient with undifferentiated chest pain focuses on identifying life-threatening conditions quickly.
- History Taking: Focus on the onset, character, radiation, associated symptoms, timing, and exacerbating/relieving factors (OPQRST).
- Physical Examination: Assess vital signs, heart sounds, lung sounds, and for signs of vascular compromise or DVT.
- Electrocardiogram (ECG): A 12-lead ECG should be obtained within 10 minutes of presentation to look for ST-segment changes, T-wave inversions, or arrhythmias indicative of ischemia.
- Cardiac Biomarkers: High-sensitivity troponin levels are crucial for diagnosing myocardial infarction.
- Chest X-ray (CXR): Helps identify alternative diagnoses like pneumonia, pneumothorax, or a widened mediastinum suggesting aortic dissection.
Features of Ischemic Chest Pain
Classic anginal pain is often described as a retrosternal pressure, heaviness, or squeezing sensation. It may radiate to the left arm, jaw, or back. Associated symptoms can include diaphoresis, nausea, dyspnea, and lightheadedness.
Aortic Dissection Red Flags
Suspect aortic dissection with a sudden, severe, “tearing” or “ripping” chest pain that radiates to the back. Key physical findings include a new aortic regurgitation murmur, pulse deficits, or significant blood pressure differentials between arms.
Pulmonary Embolism Clues
PE should be considered in patients with pleuritic chest pain, dyspnea, and tachycardia, especially with risk factors like recent surgery, immobility, or a history of DVT. The classic triad is rare; a high index of suspicion is required.
Common Benign Causes
GERD often presents as a burning retrosternal pain that is worse after meals or when lying down, and may be relieved by antacids. Costochondritis causes localized, sharp pain that is reproducible on palpation of the costosternal joints.
Frequently Asked Questions about Chest Pain
What is the first test always performed for chest pain?
A 12-lead electrocardiogram (ECG) is the first and most critical test performed on a patient presenting with acute chest pain. It provides immediate information about the heart’s electrical activity and can quickly identify life-threatening conditions like an ST-elevation myocardial infarction (STEMI).
How is “stable” angina different from a heart attack?
Stable angina is predictable chest pain that occurs with exertion and is relieved by rest or nitroglycerin. It’s caused by a fixed narrowing of a coronary artery. A heart attack (myocardial infarction) is typically caused by a sudden blockage of a coronary artery, leading to pain that is more severe, lasts longer, and occurs at rest.
Can anxiety cause real chest pain?
Yes, anxiety and panic attacks can cause chest pain that mimics cardiac pain. It is often described as sharp or stabbing and may be associated with palpitations, shortness of breath, and a sense of doom. However, it’s crucial to rule out cardiac causes first, making it a diagnosis of exclusion in an acute setting.
What does “pleuritic” chest pain mean?
Pleuritic chest pain is a sharp, stabbing pain that worsens with deep inspiration, coughing, or sneezing. It is caused by irritation of the pleura (the lining of the lungs and chest cavity) and is a common symptom of conditions like pulmonary embolism, pneumonia, or pleuritis.
