Which action is common to both angina and myocardial infarction management?

• A. Administer GTN spray
• B. Begin BLS and defibrillation
• C. Call 999 urgently
• D. Keep casualty upright to assist breathing

Answer: (D)

Chest pain from angina or a myocardial infarction often leaves the person short of breath and anxious. The most immediately comforting and broadly applicable action is to position them upright or semi-upright. This posture helps the chest expand more fully with each breath, reduces the effort required to breathe, and lowers the heart’s workload while help is being arranged. It also allows you to monitor their breathing and conscious state more easily and makes it safer to give any further instructions or interventions as advised by a responder.

Other options depend on specific circumstances. GTN spray can be helpful for known angina but isn’t guaranteed to be appropriate in an MI, especially if blood pressure is low or if the person hasn’t been prescribed it. Starting BLS and defibrillation is only needed if the person becomes unresponsive and pulseless. Calling emergency services promptly is essential in suspected heart events, but the question highlights the positioning as the common, immediate first aid measure to support breathing and comfort in both conditions.
