Recognising coronary occlusion before troponin returns
Classic ST elevation may be absent despite an occluded coronary artery requiring urgent reperfusion.

A low cholesterol risk score can mislead
Lifetime lipid exposure, inherited markers and inflammatory disease can change prevention decisions despite reassuring results.

When chest pain still needs troponin
Atypical symptoms and absent risk factors do not reliably exclude myocardial infarction.

Choose inotropes by physiology, not pressure
Inotrope choice starts with perfusion, heart rate and afterload, not blood pressure alone.

Thoracotomy decisions need more than arrest time
Wound location and ECG rhythm can sharpen thoracotomy decisions in traumatic cardiac arrest.

When ventilation makes shock worse
Positive pressure changes preload and afterload, so its haemodynamic effect depends on the failing circulation.

A raised troponin is not (always) an infarction
Troponin change identifies myocardial injury; mechanism, timing and imaging determine whether it is infarction.

The physiology changes when bypass starts
Bypass deliberately alters blood, temperature and coagulation, so abnormal numbers need physiological interpretation.

Rethinking interruptions in the emergency department
A safer ED communication system separates urgent interruption from messages that can wait.

When a pericardial effusion becomes dangerous
Tamponade depends on impaired cardiac filling and haemodynamics, not simply the size of the effusion.

Post-cardiotomy collapse needs a different algorithm
After cardiac surgery, invasive data and procedure-specific responses can matter more than a generic arrest algorithm.
