What symptom is least likely to be associated with myxedema coma?

Myxedema coma is a severe form of hypothyroidism that can lead to life-threatening symptoms. In this condition, the body's metabolism is severely depressed due to inadequate thyroid hormone levels. Given this context, understanding the typical and atypical symptoms associated with myxedema coma is crucial.

Hypothermia, bradycardia, and confusion are all classic symptoms of myxedema coma. Hypothermia occurs due to a decreased metabolic rate, causing the body to generate less heat. Bradycardia commonly reflects the slow heart rate associated with the reduced cardiovascular function prevalent in severe hypothyroidism. Confusion or altered mental status is also frequent, as severe hypothyroidism can affect cognitive function and alertness.

Hypertension, on the other hand, is not typically associated with myxedema coma. Often, patients with myxedema coma may exhibit hypotension due to decreased cardiac output and peripheral vascular resistance. Therefore, hypertension is least likely to be a symptom observed in this condition, making it the correct answer in this context.
