What is a common symptom that might indicate coronary artery spasms during a procedure?

A common symptom that can indicate coronary artery spasms is the presence of myocardial infarction (MI) symptoms. These symptoms often include chest pain or discomfort, which can radiate to the arm, neck, jaw, or back. In cases of coronary artery spasm, this pain can occur even in the absence of significant coronary artery disease and may be associated with other symptoms such as shortness of breath or sweating.

Coronary artery spasms cause temporary narrowing of the coronary arteries, leading to reduced blood flow to the heart muscle, which can mimic the presentation of an MI. Observing these symptoms during a procedure suggests that the heart may not be receiving adequate blood supply, warranting prompt assessment and management.

The other options may relate to different clinical scenarios but do not specifically indicate coronary artery spasms. Increased blood pressure could be seen in various conditions, low oxygen saturation might suggest pulmonary issues or significant cardiac compromise, and a high fever would likely reflect an infectious process rather than a direct indication of coronary artery events.
