QuestionChoice
If the right coronary artery was involved, the ST elevation would be seen in the inferior leads: II, III and AVf.

c
Right coronary artery STEMI
QuestionChoice
Unstable angina is a good differential due to the chest pain relieved by GTN spray, however unstable angina is often brought on without triggers such as exercise. Furthermore, the ECG changes, in this case, are more suggestive of a STEMI.

Unstable angina
QuestionChoice
Although this patient experienced chest pain on exertion which was relieved by GTN spray, the ECG changes and pain radiation are more suggestive of a STEMI.

b
Stable angina
QuestionChoice
The chest pain and ST elevation here suggest that the patient is having a STEMI. The V1-V4 ECG leads view the heart from the anteroseptal plane, so it is most likely that the left anterior descending artery is blocked.

a
Left anterior descending artery STEMI
QuestionChoice
If the left circumflex artery was involved, ST elevation would be seen in the lateral leads; I, AVL, V5 and V6.

A 60-year-old male presents to A&E with central crushing chest pain that has been ongoing for 1 hour. He says the pain came on while he was playing tennis. The pain radiates to his left arm and his jaw.

The paramedics gave him GTN spray in the ambulance which reduces the severity of his symptoms. An ECG is done which shows ST elevation in V1 - V4.

What is the most likely diagnosis?
