Chelsea Handler reveals she had a 'hospital scare' induced by years of intense ...

Chelsea Handler is opening up about a recent health scare that led to her canceling multiple dates of her Vaccinated & Horny tour earlier this year.

The topic came up when the comedian, 47, was asked about 'not taking [herself] too seriously' during an interview with E!

Handler revealed she'd been unknowingly taking herself way too seriously for many years, which led to her suffering a 'hospital scare' in February after a comedy show in Seattle, Washington.

'I had this cardiomyopathy, which means, like, an adrenaline shot to the heart,' she explained.

According to the CDC, Cardiomyopathy 'represents a collection of diverse conditions of the heart muscle' that reduce the 'heart muscle’s ability to pump blood' which can lead to 'irregular heartbeats, the backup of blood into the lungs or rest of the body, and heart failure.'

While speaking with a doctor at the hospital, Handler wondered if her issue was something that had occurred out of nowhere or if it was something that'd been building over time.

'I was like, "Was this an instance, or was this building?" And the doctor says, "Well, it's an instance, but you've basically been very stressed for a long period of time and you probably did not recognize that." And I was like, "Oh, s**t."' 

Handler continued, 'And he goes, "I don't know a lot about you, but isn't your whole shtick that you don't take yourself too seriously?" And I went, "Yeah…" And he goes, "Well then you should start taking your own advice because you're taking yourself too seriously." 

'And I thought, "God, you're right. What am I doing here? I'm stressed out so much that I landed in the hospital?" I'm fine now. But I was like, "Good advice: Practice what you preach." It was a good reminder to let everything go.'
