Key result
Decreased apical uptake on BMIPP scintigraphy recovered in 3 months, while decreased apical uptake on MIBG scintigraphy persisted for 6 months, indicating a discrepancy in sympathetic innervation.

May inform mechanisms of apical akinesia in takotsubo cardiomyopathy; hypothesis-generating from Level 5 evidence and should not change practice.

Discrepancy in sympathetic innervation recovery between apical and basal regions may explain the characteristic left ventricular apical akinesia in takotsubo cardiomyopathy.
Moriya et al. (2002) conducted a case report in Takotsubo cardiomyopathy (n=1). I-123-BMIPP and I-123-MIBG myocardial scintigraphy was evaluated on Myocardial uptake and washout rate. Decreased apical uptake on BMIPP scintigraphy recovered in 3 months, while decreased apical uptake on MIBG scintigraphy persisted for 6 months, indicating a discrepancy in sympathetic innervation.
