Abstract: Thyrotoxic cardiomyopathy is a rare but potentially fatal form of cardiomyopathy. It is a diagnosis of exclusion and prompt identification is crucial as it is a reversible cause of heart failure and cardiac function can recover after achieving euthyroid using anti-thyroid medications. The case record of a 40-year-old male who presented to the cardiology clinic of the University of Port Harcourt Teaching hospital was utilized.
Case
Presentation: We present a case of 40-year-old business man who presented with
progressive dyspnea of two weeks and bilateral leg swelling of one week on
referral from a private center. He reported paroxysmal dyspnea, orthopnea and
easy fatiguability. He volunteered further history of palpitation, heat
intolerance, hyper-defecation and jaundice. He had noticed a neck swelling of
two years. His initial evaluation is notable for a grade 4 finger clubbing,
jaundice, bilateral pitting leg edema, tachypnea, tachycardia with diffused
apex, S1, S2 and grade 3 pansystolic non radiating murmur, bi-basal rales,
mildly tender hepatomegaly and ascites. Neck exam was remarkable for anterior
neck mass of 14cm by 10cm moved with swallowing. Initial laboratory work-ups
were notable for CXR evidence of cardiomegaly and unfolded aorta, moderately
low TSH and mildly elevated T3, T4, and elevated total and unconjugated
bilirubin, low albumin. Echo was consistent with heart failure with reduced EF.
It was evident that our patient has thyrotoxic cardiomyopathy. Endocrine team
was consulted early and patient was managed with combination of carbimazole and
anti-failure regimen. After a hospital stay of about three weeks, he made a
remarkable recovery and was discharged home fairly stable. Thyrotoxic
cardiomyopathy is a rare but potentially lethal complication of thyrotoxicosis
which is reversible if promptly identified and euthyroid status is achieved
using anti-thyroid drugs. DOI: http://dx.doi.org/10.51505/ijmshr.2026.10208 |
