Which statement best describes the response of heart failure symptoms in wet beriberi to thiamin supplementation?

• A. Worsening
• B. Improvement only after months
• C. Rapid improvement
• D. No change

Answer: (C)

Thiamine is essential for cardiac energy production, and in wet beriberi deficiency directly impairs myocardial metabolism. When thiamine is given, the heart’s energy supply quickly improves, leading to a rapid reversal of heart failure symptoms—often within hours to a day or two. This swift response is a hallmark of thiamine-responsive wet beriberi and helps distinguish it from other causes of cardiomyopathy that don’t improve so quickly. If symptoms don’t show quick improvement after supplementation, consider other diagnoses or coexisting deficiencies and reassess management.
