When the heart breaks, the kidneys follow: A case of Takotsubo syndrome

We report the case of Takotsubo syndrome in a 32-year-old man with no particular medical history who presented with acute heart failure associated with severe renal failure following intense emotional stress. Cardiac and renal dysfunction gradually resolved without specific treatment, although there was a time lag between cardiac recovery (day 15) and renal recovery (day 30). Several factors make this observation particularly interesting: the young age and male gender of the patient; the presence of an exclusively emotional trigger in a man, which is unusual; and the severity of the renal damage, which took several weeks to improve. This severe acute kidney failure resulted from a complex interaction between renal hypoperfusion, massive neurohormonal activation, and direct renal vasospasm, leading to acute tubular necrosis. This observation highlights the importance of considering Takotsubo syndrome in the differential diagnosis of acute renal failure associated with unexplained cardiac dysfunction, particularly in patients who do not fit the typical demographic profile.
