Which set lists warning signals suggesting acute coronary syndrome in a patient with chest pain?

• A. Diaphoresis, dyspnea, radiation to jaw/arm, and pain lasting more than several minutes.
• B. Dizziness, fever, cough, and fatigue.
• C. Nausea, stomach pain, back pain, and headache.
• D. Shortness of breath only.

Answer: (A)

When chest pain could be from acute coronary syndrome, the strongest warning signals are signs of autonomic activation and ongoing ischemia: sweating (diaphoresis), shortness of breath (dyspnea), pain that radiates to the jaw or arm, and pain that lasts for several minutes. These features reflect the body's response to reduced blood flow to the heart and the typical pattern of ischemic chest pain that can spread along nerves to other regions. They help distinguish ACS from non-cardiac causes of chest pain. The other sets include symptoms that are less specific for ACS, such as fever or cough (which point toward infection), GI or back symptoms without the classic ischaemic pattern, or shortness of breath by itself. On their own, those signs don’t strongly indicate ACS. Therefore, a presentation featuring diaphoresis, dyspnea, radiation of pain to the jaw or arm, and pain lasting several minutes best matches the warning signals for acute coronary syndrome.
