Which of the following is a symptom associated with acute coronary syndrome (ACS) other than chest pain?

Dizziness is a recognized symptom associated with acute coronary syndrome (ACS) beyond the classic presentation of chest pain. In patients experiencing ACS, dizziness can occur due to decreased blood flow to the brain, which may happen as a result of compromised heart function. This symptom can indicate that the heart is struggling to supply adequate blood, leading to feelings of lightheadedness or faintness.

When evaluating other options, fatigue, sweating, and knee pain can also be associated with ACS in certain contexts. However, dizziness is particularly notable in the acute setting, as it arises from the immediate cardiovascular status of the patient. Fatigue may be more gradual and linked to chronic heart conditions, while sweating is a common yet less specific symptom. Knee pain does not typically relate to ACS and is more indicative of musculoskeletal issues rather than cardiovascular events.
