Key result
SAH-induced reverse Takotsubo cardiomyopathy patients were younger (51.8 vs 63.5 years, p=0.04) and had higher plasma epinephrine (809 vs 380 pg/mL, p=0.04) than those with typical TTC.

Reverse Takotsubo in SAH should not alter current management; leaves open epinephrine's role in subtype-specific trials.

Reverse Takotsubo cardiomyopathy associated with subarachnoid hemorrhage occurs in younger patients and is associated with higher epinephrine levels compared to typical Takotsubo, though clinical outcomes like 90-day mortality are similar.
Kumai et al. (2016) conducted an observational in Subarachnoid hemorrhage-induced Takotsubo cardiomyopathy (n=31). Reverse Takotsubo cardiomyopathy vs. Typical Takotsubo cardiomyopathy was evaluated on Plasma epinephrine levels (pg/mL) (p=0.04). SAH-induced reverse Takotsubo cardiomyopathy patients were younger (51.8 vs 63.5 years, p=0.04) and had higher plasma epinephrine (809 vs 380 pg/mL, p=0.04) than those with typical TTC.
