摘要
A 77-year-old man visited our hospital complaining of aggravated exertional chest pain. He was diagnosed with syndrome X 7 years ago and underwent medical treatment in a regional hospital. Coronary angiography and echocardiography did not show any significant abnormalities. On the seventh in-hospital day, cardiogenic shock developed and echocardiography showed a dilated left ventricular (LV) cavity and severe LV systolic dysfunction. We thus inserted an intra-aortic balloon pump for hemodynamic support and were forced to maintain it because of weaning failure several times. Finally, heart transplantation was the decided necessary procedure. After successful heart transplantation, the biopsy specimen revealed a wild-type transthyretin deposition indicating senile systemic amyloidosis in the intramuscular coronary vessels and interstitium. Cardiac biopsy at the 4-year follow-up showed no recurrence of amyloid deposition.
