Chest pain is one of the most common and highest-stakes presentations in clinical medicine.
The challenge is not recognizing it. The challenge is knowing exactly what to do next, quickly, consistently, and safely.
This guide gives you a step-by-step algorithm you can follow in real time, whether you are in the emergency department or on rounds.
Step 1: Immediate Triage and Stability Check
Start with one question: Is this patient stable?
Assess:
•
Airway, breathing, circulation
Red flags requiring immediate action:
•
Ongoing severe chest pain
If unstable: Activate emergency pathway. Place on monitor. Establish IV access. Give oxygen if hypoxic. Prepare for immediate intervention. Do not delay for labs.
Step 2: Rule Out Life-Threatening Causes First
Before anything else, consider the "can't miss" diagnoses:
•
Acute coronary syndrome (ACS)
Your initial evaluation should always be directed at ruling these out.
Step 3: Obtain an EKG Within 10 Minutes
Interpret immediately for:
•
New left bundle branch block
If STEMI: Activate cath lab immediately. Give aspirin. Start guideline-directed therapy. Do not wait for troponin.
Step 4: Focused History That Changes Management
You are not collecting trivia. You are gathering decision-making data.
Key elements:
•
Onset: sudden vs gradual
•
Character: pressure, sharp, tearing
•
Radiation: arm, jaw, back
•
Associated symptoms: diaphoresis, dyspnea, syncope
•
Risk factors: CAD, smoking, diabetes, hypertension
High-risk features:
•
Typical anginal description
Step 5: Physical Exam with Purpose
Look for clues that redirect your algorithm:
•
Unequal blood pressures; consider dissection
•
Tachycardia + hypoxia; consider PE
•
Absent breath sounds; consider pneumothorax
•
New murmur; consider mechanical complications
The exam is not routine. It is strategic.
Step 6: Initial Labs and Imaging
Order immediately:
Use results to refine probability, not to delay action.
Step 7: Risk Stratification
Once STEMI is excluded, the next step is risk stratification.
Use structured tools:
HEART Score components:
Interpretation:
Consider discharge with follow-up
Observation and further testing
Step 8: Decide Disposition
This is where most errors occur.
Negative troponins, non-ischemic EKG, low HEART score
Discharge with clear follow-up
Observation, repeat troponins, possible stress testing
Positive markers or high clinical suspicion
Admit, cardiology consult, aggressive management
Step 9: Do Not Miss Alternative Diagnoses
If ACS is ruled out, revisit your differential:
•
PE; Wells score, D-dimer, CT angiography
•
Aortic dissection; CT angiography, blood pressure control
•
Pericarditis; positional pain, diffuse ST elevation
•
GERD or musculoskeletal; diagnosis of exclusion
Step 10: Reassess and Document Clearly
Clinical decisions evolve.
Reassess:
Document:
This protects both patient and clinician.
Common Pitfalls in Chest Pain Management
•
Over-relying on a single troponin
•
Ignoring atypical presentations
•
Failing to risk stratify formally
Avoiding these mistakes is as important as following the algorithm.
Why a Structured Algorithm Matters
In real clinical settings, time and cognitive load are limited.
A structured approach:
This is the difference between guessing and practicing with precision.
