I thought that I should let you know

Why does the guy in "Damaged" have to fix the girl's broken heart, if it was caused by the one before?

For Once I Wish a Song Could Be Literal

On "Damaged", the song by that Pussycat Dolls wannabe group Danity Kane (terrible name, by the way):

Am I the only one who wants the song to be about a physically damaged heart, as in a defect or murmur?

Just kind of funny if you imagine they’re singing this to a doctor a surgeon, trying to find one who can repair their heart.

Hey, some of the lyrics could be interpreted that way if so desired:

Do, Do you got a first aid kit handy?
Do, Do you know how to patch up a wound?
Tell me, Are-are-are-are you?
Are you patient,
Understanding?
'Cause I might need some time to clear the hole in my heart and I
I've tried every remedy
And nothing seems to work for me

So how you gonna fix it, fix it, fix it?
(Baby, I gotta know)
How you gonna fix it, fix it, fix it?
(What you are gonna do, baby?)
How you gonna fix it, fix it, fix it?
(Baby, I gotta know)
How you gonna fix it, fix it, fix it?
(What you are gonna do?)

Edited to add: Ok, in the video they add in a little hospital storyline at the end. But don't watch it, it's boring. My idea is much better.
