Which statement best describes the initial evaluation step for a patient with chest pain suggestive of ACS?

• A. Obtain 12-lead ECG within 10 minutes
• B. Start thrombolysis immediately
• C. Initiate high-flow oxygen to all patients
• D. Perform chest X-ray to rule out pneumonia

Answer: (A)

In someone with chest pain suggestive of ACS, the first move is to obtain a 12-lead ECG as quickly as possible. This tiny test gives an immediate snapshot of the heart’s electrical activity and can reveal ST-segment elevations that define a STEMI, or other patterns that point to NSTEMI or unstable angina. Recognizing STEMI right away is crucial because it triggers urgent reperfusion therapy (PCI or thrombolysis if PCI isn’t available) and time to treatment directly affects heart muscle survival. That’s why the target is to perform a 12-lead ECG within about 10 minutes of first medical contact. Other steps, like starting thrombolysis before confirming the ECG, giving high-flow oxygen to everyone, or doing a chest X-ray to rule out pneumonia, do not provide the essential diagnostic information needed to guide immediate therapy and can be inappropriate or less urgent as the initial action. Oxygen is reserved for those who are hypoxemic or have other indications, and a chest X-ray, while useful, does not replace the need for an early ECG to steer urgent ACS management.
