How does timing of chest pain help differentiate its cause?

• A. Pain after exercise or provoked by movement is less likely to be cardiac ischaemic.
• B. Pain occurring at rest is diagnostic of ischaemia.
• C. Immediate pain after meals indicates ischaemia.
• D. Long-lasting pain regardless of activity indicates ischaemia.

Answer: (A)

Timing helps distinguish cardiac ischemia from non-cardiac chest pain. Angina from ischemia usually appears with physical exertion or emotional stress and eases with rest or nitroglycerin. If chest discomfort shows up after finishing exercise or is triggered by movement, this pattern is more consistent with non-cardiac causes such as musculoskeletal or GI problems, making ischemia less likely. Resting pain, post-meal pain, or pain that lasts regardless of activity are not reliable indicators of ischemia on their own and can point to other etiologies or more complex cardiac events, respectively.
