This study aims to investigate physicians' awareness regarding patients presenting with potential acute ischemic chest pain. It focuses on various electrocardiogram (ECG) patterns requiring prompt catheter lab activation for reperfusion therapy alongside other ECG mimics that may lead to false catheter lab activations.

Chest pain is the second most common complaint in adult emergency department (ED) patients in the United States. Most visits result in a diagnosis of noncardiac chest pain and approximately half in nonspecific chest pain. Roughly 6% are ultimately diagnosed with a life-threatening condition, which is overwhelmingly (>90%) acute coronary syndrome (ACS).

The term acute coronary syndrome (ACS) is applied to patients in whom there is a suspicion or confirmation of acute myocardial ischemia or infarction. ST-elevation myocardial infarction (STEMI), Non-ST-elevation MI (NSTEMI), and unstable angina are the three traditional types of ACS.

Inclusion Criteria:

• Age from 25 to 65 years.
• Both sexes.
• Physicians who treat patients with possible acute chest pain.

Exclusion Criteria:

- Participants who failed to complete the survey questions.

A consecutive sample of 500 physicians who treat patients with possible acute ischemic chest pain will be the subject of this cross-sectional survey study. These doctors will include emergency physicians, cardiologists, internal medicine/acute medicine specialists, general practice or family physicians, anesthesiologists, and intensive care physicians of both sexes, with varying degrees of experience and post-graduate clinical training, from all over the world.

The data will be available upon a reasonable request from the corresponding author after the end of study for one year.
