Background: Takotsubo syndrome (TTS) is a syndrome with ambiguous pathophysiology. Impaired kidney function (KF) seems to impact the outcome of patients with TTS. We hypothesized that KF worsens the outcome among TTS patients and furthermore. TTS patients with concomitant KF experience more adverse events compared to myocardial infarction (MI) patients with concomitant KF. https://www.chiggate.com/red-sensation-hydrangea-supply/
