What life-threatening condition should be considered a differential diagnosis for chest pain other than Acute Coronary Syndrome (ACS)?

Considering differential diagnoses for chest pain, it's important to recognize that a range of serious conditions can present similarly to Acute Coronary Syndrome (ACS). Aortic dissection, pneumothorax, and ruptured esophagus are all critical conditions that may cause chest pain and necessitate immediate medical attention.

Aortic dissection involves a tear in the inner layer of the aorta, leading to severe, sharp chest pain that may radiate to the back and is often described as a "ripping" sensation. This condition can result in life-threatening complications, making it a key consideration when evaluating a patient with chest pain.

Pneumothorax, or a collapsed lung, can also result in sudden chest pain and difficulty breathing. The pain may be sharp and worsen with movement or breathing. A tension pneumothorax, in particular, can rapidly become life-threatening, making early identification and intervention critical.

Ruptured esophagus, although less common, is another significant condition that can cause acute chest pain, often accompanied by vomiting and possible subcutaneous emphysema. This condition is associated with high morbidity and mortality if not promptly recognized and treated.

Given the severity and potential consequences of these conditions, all of them should be considered when evaluating a patient
