Acute chest pain and suspected ACS

A disciplined approach to immediate threats, ECG interpretation, serial assessment and early specialist escalation.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional 61-year-old develops central chest pressure with sweating and nausea while walking to work.

01 · RECOGNISE

Frame the danger first.

  • Treat suspected acute coronary syndrome as time-sensitive while considering other lethal causes of chest pain.
  • A normal first ECG does not by itself exclude acute coronary syndrome.
  • Interpret symptoms, ECG findings, haemodynamics and biomarkers together.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Perform immediate clinical assessment, observations and a 12-lead ECG using the local chest-pain pathway.
  2. Escalate haemodynamic instability, ongoing pain or diagnostic ECG changes urgently.
  3. Use current local/NICE antiplatelet, anticoagulation and reperfusion pathways; check contraindications.
  4. Repeat assessment and ECGs if symptoms continue or evolve.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Shock, malignant arrhythmia, acute heart failure or ongoing severe pain
  • Diagnostic ST-segment elevation or dynamic ischaemic change
  • Features suggesting aortic syndrome, pulmonary embolism or tension pneumothorax
04 · COMMON ERRORS

What makes care less safe.

  • Reassurance from a single normal ECG or initial biomarker
  • Giving protocol treatment without checking bleeding risk or alternative diagnoses
  • Failure to document symptom timing and dynamic change
05 · STRUCTURED HANDOVER

Say the concern plainly.

This is suspected ACS with symptoms beginning at [time]. The patient is [stable/unstable]; ECG shows [finding] and serial change is [present/absent]. I need urgent review for the appropriate invasive or reperfusion pathway.
