I have Recurrent Takotsubo. Does anyone else have this condition?

I have had 5 Takotsubo events. This a rare condition that they have not been able to fully understand. I had one as recently as June 21st this year. Along with that I also have microvascular dysfunction that no medication has helped control. I have nightly angina that started in Sept. 2019. I wake up with chest pain that last less than a minute then breakout in a sweat. Sometimes I can have this multiple times a night. I have had 5 sleep studies. I do not have apnea and they do not see anything on the cardiac monitor. Does anyone else have these conditions?
