Acute assessment of chest pain

A medical consult is recommended where there is no specific protocol for a condition

  • Always consider sepsis — signs and symptoms can include
    • High or low temperature
    • Fast breathing
    • Fast pulse
    • Low BP or dizziness
    • Confusion and/or agitation
  • Treat as serious and call for help
  • Always assume chest pain is cardiac in origin until medical officer is able to rule out
  • Always do full assessment — many heart attacks are missed because symptoms not typical. Especially in young adults, women, people with diabetes
  • Use defibrillator as a monitor
Red Flags — Urgent Medical Consult
  • Pressure or pain in chest that may spread to shoulders, arms, neck, jaw or back
  • Chest pain that lasts more than 10 minutes
  • Dizziness, feeling faint, anxious or nauseous
  • Short of breath, fast breathing, trouble breathing, pain on breathing
  • Sweating
  • Painful swollen leg
  • Haemoptysis (coughing up blood)

Check

  • Do 12 lead ECG immediately — urgent medical consult within 10 minutes
    • Leave leads on — will need to repeat
  • Calculate age-appropriate REWS
    • Adult — AVPU, RR, O2 sats, pulse, BP, Temp
    • Child (less than 13 years) — AVPU, respiratory distress, RR, O2 sats, pulse, central capillary refill time, Temp
  • Weight, BGL
  • If available POC Test — Troponin
  • History and head-to-toe exam

Signs and symptoms

Possible cause

Pain can be dull, tight, heavy, squeezing

Usually in centre of chest but can be in shoulders, arms, back, neck, jaw. May be felt on right side

Cool and sweaty, nauseous, short of breath

Pain often occurs with exercise or exertion of any kind (walking, arguing)

Heart pain medical consult

Heart attack OR Angina — episodic chest pain

Severe pain through to the back — may have neurological deficit.

Older person with a history of hypertension —may be complicated by AMI

Aortic dissection medical consult

Sudden onset of unilateral pain

Pain sharp, mostly on deep breathing

May have fast or shallow breathing or short of breath

May have a history of cough or trauma

Reduced breath sounds or chest movement on one side

More common in men 20-40 years, COPD

Pneumothorax medical consult

Fever, cough, shortness of breath

Pulmonary embolus (blood clot in lung) medical consult

Burning or sharp pain

Abdominal tenderness, chest or shoulder discomfort

Peptic ulcer

History of injury

Pain on moving shoulders or upper body and settles when still

Local muscle tenderness

Muscle pain medical consult

Tenderness to palpation of costochondral joints

Costochondritis medical consult
