When to Use

When to Use

  • Adult patients presenting to the emergency department with non-traumatic chest pain suspicious for ACS.
  • Specifically designed to identify low-risk patients who can be safely discharged after a 2-hour observation and troponin period.

How it Works

The Logic

The Vancouver Chest Pain Rule utilizes a sequential decision tree including ECG, Troponin, medical history, and physical examination findings.

Low-Risk Criteria

  • A patient is LOW-RISK if: They have a normal ECG AND normal 2-hour troponin.
  • AND NO prior history of CAD or nitrate use.
  • AND satisfy age/exam criteria: Age < 40 OR (Age 40-50 with pain reproducible by palpation).
CLINICAL INSIGHT

Practical Pearls

Why Palpation Matters

The rule importantly quantifies the clinical "hunch" that musculoskeletal pain is low risk. In patients aged 40-50, reproducibility of pain on palpation is a powerful negative predictor of ACS within this specific rule framework.

Safety Profile

The rule has a reported sensitivity of nearly 99% for 30-day MACE, making it one of the safest rapid rule-out protocols available.
