Which of the following is not a symptom of angina?

In the context of angina, chest pain is a hallmark symptom, typically experienced as discomfort or pressure in the chest due to insufficient blood flow to the heart muscle. Dizziness and nausea can also be associated symptoms, as the compromised blood flow can affect overall circulation and lead to various responses from the body.

Confusion, on the other hand, is not typically recognized as a symptom of angina. It may occur in more severe cardiac conditions or situations involving inadequate oxygen delivery to the brain, like during a heart attack, but it is not a direct symptom of angina itself. Thus, identifying confusion as the option that does not align with the typical presentation of angina helps clarify the defining symptoms associated with this condition.
