Essential Questions to Ask When Evaluating Chest Pain
When evaluating a patient with chest pain, a systematic approach focusing on specific characteristics of the pain and associated symptoms should be employed to identify potentially life-threatening conditions and guide appropriate management. 1
Chest Pain Characteristics to Assess
Nature of Pain
- Is the pain retrosternal discomfort (heaviness, tightness, pressure, squeezing)? Suggests cardiac ischemia
- Is the pain sharp and increases with inspiration or lying supine? Suggests pericarditis
- Is the pain described as "ripping" or "tearing"? Suggests aortic dissection
- Is the pain localized to a very specific area or reproducible with palpation? Suggests non-cardiac origin 1
Onset and Duration
- Did the pain gradually build over minutes? Suggests angina
- Was the onset sudden with "ripping" quality? Suggests aortic dissection
- Is the pain fleeting (seconds duration)? Less likely to be cardiac
- Has the pain been persistent or worsening? Suggests need for urgent evaluation 1
Location and Radiation
- Is the pain retrosternal with radiation to left arm, shoulders, neck, or jaw? Suggests cardiac origin
- Does the pain radiate to both arms? Highly specific for ACS (specificity 96%) 2
- Does the pain radiate to the back? Consider aortic dissection
- Does the pain radiate below the umbilicus or hip? Less likely cardiac 1
Precipitating Factors
- Is the pain triggered by physical exertion or emotional stress? Suggests angina
- Does the pain occur at rest or with minimal exertion? Suggests ACS
- Is the pain positional or affected by movement? Suggests musculoskeletal origin
- Is the pain pleuritic (worsened by breathing)? Suggests pulmonary or pleural etiology 1
Relieving Factors
- Note: Relief with nitroglycerin is not necessarily diagnostic of myocardial ischemia 1, 3
- Does rest relieve the pain? Suggests stable angina
- Does the pain worsen in supine position? Suggests pericarditis 1
Associated Symptoms
- Dyspnea, diaphoresis, nausea/vomiting? Suggests cardiac origin
- Lightheadedness, presyncope, or syncope? Suggests significant cardiac issue
- Fever? Suggests infectious etiology (pericarditis, pneumonia)
- Palpitations? Consider arrhythmia as cause or consequence 1
Physical Examination Focus Points
Vital Signs
- Tachycardia and hypotension? Suggests cardiogenic shock
- Tachycardia with dyspnea? Present in >90% of pulmonary embolism cases
- Fever? Suggests infectious etiology 1
Cardiovascular Examination
- Pulse differential between extremities? Suggests aortic dissection
- Presence of S3, murmur, or crackles? Suggests heart failure or valvular disease
- Pericardial friction rub? Suggests pericarditis 1
Respiratory Examination
- Unilateral decreased or absent breath sounds? Consider pneumothorax
- Regional dullness to percussion or egophony? Suggests pneumonia
- Subcutaneous emphysema? Consider esophageal rupture 1
Chest Wall Examination
- Tenderness of costochondral joints? Suggests costochondritis
- Reproducible pain with palpation? Suggests musculoskeletal origin 1
Special Considerations for Older Patients
For patients ≥75 years of age, ask about:
- Shortness of breath
- Syncope or near-syncope
- Acute confusion/delirium
- Recent unexplained falls 1
Diagnostic Testing Questions
ECG Considerations
- Has an ECG been performed within 10 minutes of arrival? Required for all chest pain patients
- Are there any ST-segment elevations or depressions? ST-depression has high specificity (95%) for ACS
- Are there any new T-wave inversions or other ischemic changes?
- For non-diagnostic initial ECG in suspected ACS, serial ECGs should be performed 1
Cardiac Biomarkers
- Has cardiac troponin been measured as soon as possible after presentation?
- Are serial troponin measurements planned if initial is negative but suspicion remains high? 1
Risk Stratification
Consider using validated risk scores:
- HEART score (History, ECG, Age, Risk factors, Troponin)
- TIMI score (Thrombolysis in Myocardial Infarction)
These scores incorporate history elements with other clinical data and significantly improve diagnostic accuracy compared to history alone 2
Common Pitfalls to Avoid
Assuming relief with nitroglycerin confirms cardiac origin - this is not a reliable diagnostic criterion 1, 3
Dismissing chest pain in younger patients - ACS can occur at any age
Over-relying on "typical" vs "atypical" categorization - instead focus on specific characteristics that increase or decrease likelihood of ACS 1
Delaying ECG beyond 10 minutes - this can significantly impact outcomes for STEMI patients 1
Discharging patients with concerning symptoms without appropriate testing - history alone cannot safely rule out ACS 4, 2
Failing to consider non-cardiac life-threatening causes - such as aortic dissection, pulmonary embolism, pneumothorax, or esophageal rupture 5
By systematically addressing these key questions during evaluation, clinicians can better identify patients with potentially life-threatening causes of chest pain and ensure appropriate management to reduce morbidity and mortality.
