What does a new onset or definite change in chest pain prior to exercise indicate?

• A. It can signal unstable angina or myocardial ischaemia, representing a contraindication to unsupervised exercise.
• B. It indicates dehydration.
• C. It is normal with exercise.
• D. It is not related to exercise safety.

Answer: (A)

A new onset or definite change in chest pain before exercising signals potential myocardial ischemia or unstable angina. When the heart isn’t getting enough blood, chest pain can appear, and a new or changing pattern is a warning that exercise could provoke a serious cardiac event. Because of that risk, such symptoms are a contraindication to unsupervised exercise and typically require medical evaluation and clearance before any exercise program is resumed. This isn’t simply dehydration or a normal reaction to effort; a new or changing chest pain pattern indicates possible instability and safety concerns that need professional assessment prior to continuing.
