Heart attack or panic attack?

Approximately one sixth of the patients treated at Emergency Heart Care units is having a panic attack rather than heartproblems. Indeed a panic attack could have some of the same symptoms as a heart attack (for example: chestpain, heart palpitations, being short of breath).
In Holland, this was a reason for a psychiatrist to join the team of cardiologists, to screen every patient showing up at the Emergency Heart Care. This way, patients actually suffering from a panic attack could get the right treatment faster.

PANIC ROOM

Urban artist Tilt designed this room for a hotel in Marseille, France. It's called "panic room" and it conveys indeed a powerful sentiment of anxiety".
I wouldn't fancy sleeping there but it's interesting how spaces and colors can influence your mood.
The issue maybe that the room is cut in half in a threatening way (for me at east). What you think?
