Does the use of β blockers prevent cardiac rupture in patients with Takotsubo cardiomyopathy?
Beta blockers may protect against cardiac rupture in Takotsubo cardiomyopathy, a complication potentially driven by higher double product and ejection fraction.
CR as a complication of TSC could be more common than recognized. Higher double product and ejection fraction suggest higher fluctuation of intracardiac pressure and may cause CR in TSC. Use of β blockers in TSC may provide protection against CR.
