Description
Jin Bai and colleagues report a 2026 case of a 56-year-old man whose acromegaly-driven heart failure improved only after resynchronisation therapy with a defibrillator. Six months of hormone-blocking drugs plus heart failure care lifted his pumping and hormone levels, yet a sustained dangerous rhythm then triggered acute failure. His starting ejection fraction had been just 16%, with complete left bundle branch block.
After the resynchronisation-defibrillator implant, no further failure flare-ups occurred and ejection fraction reached 48%, with markedly better left ventricular synchrony. Normalising growth hormone alone had not undone the heart muscle damage. The case urges timely device therapy in advanced acromegalic heart disease, rather than waiting on hormone control alone.
