In patients with aneurysmal subarachnoid hemorrhage, Takotsubo syndrome occurs in <10% of cases and should not delay aneurysm treatment, as outcomes are primarily driven by the hemorrhage.
May support echocardiography for TTS detection in aSAH; leaves open prospective outcome studies before practice change.
Takotsubo syndrome (TTS) can result in acute heart failure and lead to a potentially life-threatening complication of aneurysmal subarachnoid hemorrhage (aSAH). The incidence of TTS in aSAH is less than 10% of all patients with aSAH, with a preponderance of postmenopausal women. Early indicators of TTS include elevated serum troponin levels and electrocardiographic abnormalities. The key finding is left ventricular wall motion abnormality. Echocardiography and coronary angiography help to establish the diagnosis. Vasopressors, milrinone, levosimendan, insulin, and anticoagulation may be required. The value of beta-blockers is a matter of controversy. TTS must not delay the treatment of a ruptured aneurysm. The clinical outcome in patients with aSAH and TTS is mostly determined by the aSAH and not the TTS.
