High-output congestive heart failure (CHF) is a symptom of which type of beriberi?

High-output congestive heart failure (CHF) is associated with wet beriberi, which is a clinical manifestation of thiamine (vitamin B1) deficiency. Wet beriberi primarily affects the cardiovascular system and can lead to symptoms such as edema, tachycardia, and high-output heart failure due to fluid overload and impaired cardiovascular function.

In wet beriberi, the deficiency of thiamine causes a disruption in the metabolism of carbohydrates, leading to an accumulation of pyruvate and subsequent lactic acidosis. This metabolic derangement places additional stress on the heart, resulting in high-output heart failure as the heart attempts to meet the increased metabolic demands.

The relationship between wet beriberi and high-output CHF underscores the importance of thiamine in maintaining proper heart function and demonstrates how its deficiency can lead to significant cardiovascular complications. In contrast, dry beriberi primarily affects the nervous system, leading to peripheral neuropathy and does not typically present with high-output heart failure. Wernicke's encephalopathy, while related to thiamine deficiency, is characterized mainly by neurological deficits such as confusion, ataxia, and ophthalmoplegia and is not directly linked to heart failure. Therefore, the identification of wet beriber
