Introduction:The most common acute coronary syndrome (ACS) symptom is chest pain. Chest pain is an umbrella term more precisely described using words like pressure or tightness. Previous studies have not explored the lay public’s conceptions of ACS-related chest pain. were recruited in May and June 2023.

Upon questioning patient, he denies having any chest pain or chest tightness of any sort. In the absence of chest pain and negative troponin , it appears less likely that he is having acute coronary syndrome though EKG appears concerning. Pericarditis would be even more unlikely in someone without chest pain.
