If you don't mind, that is...
A panicked look on the face. A gasp. Screaming out ‘HOLY SHIT MY HEART!’ These are all things ponies might do when having a heart attack. Probably, the most important one must do, is inform in a nearby pony that you are in need of help. Followed by that, CPR usually, if you’re not already getting rushed to the hospital. The list goes on. Anyway, you don’t usually notice you’re having a heart attack until your heart feels like it’s exploded. So screaming for help is probably the first thing to do on the list.
“Oh dear…”
Very good Fluttershy!
Fluttershy limped out of her house, not thinking to possibly inform any of her woodland friends to get help. Fortune smiled upon her, as Rainbow Dash was speeding towards her from Ponyville.
“Hey Flutters!”
“O-oh, um.”
“I’ve been working on a new trick!”
“That’s, that’s nice, but-”
“It’s so amazing, it’ll leave you gasping for air!”
Fluttershy wheezed.
“Watch THIS!”
Rainbow Dash proceeded to do the normal procedure for a Sonic Rainboom. When she broke the barrier. Right as the Sonic Rainboom washed over Fluttershy, her heart attack stopped. Breathing a sigh of relief. She watched Rainbow Dash fly up to the left diagonally, do a loop, fly up, and dive down again. Forming a large R with her enhanced rainbow trail from the Sonic Rainboom, and ending it, with another Sonic Rainboom. The color washed over Fluttershy again.
Giving back her heart attack.
“Pretty cool huh?!?” Rainbow Dash posed in front of Fluttershy.
Fluttershy stumbled and fell on her front left leg. Choking, reaching out a hoof towards Rainbow.
“Hah! I KNEW it’d leave you out of breath!”
“E-excuse me, if you don’t mind…”
“Sorry Fluttershy, it still needs a little work! I’ll talk to you later, alright?”
Not waiting for a response, Rainbow Dash sped off.
Fluttershy blacked out for two seconds.
Forcing herself forward, Fluttershy continued down to the hospital. Until she ran into Applejack.
“Well howdy Fluttershy!”
“O-oh, hello *cough* Applejack… If you could be so kind-”
“Well gee Fluttershy, you look worse than a rattlesnake in a icebox!”
“Oh, yes. I think I’m having a-”
“Oh, did you come down with ah cold like Applebloom here?” Applejack pointed to Applebloom.
“No. Sorry, I-”
“Do you need a ride to doctor Sugarcube? Hop on aboard.”
Choosing to count her blessings. Fluttershy jumped onto the wagon. And smashed her face into the side as she failed to jump high enough.
---
“...? …!”
Getting shaken awake by someone. Fluttershy tried to stand up. And failed. With the lack of oxygen going towards her head, everything was a blur of radical colors. In front of her was a liquid mess of Jack Daniels whiskey somewhat in the form of a pony. Wearing a taco on it’s head.
“...!”
With a slap on her back, Fluttershy’s heart somehow was working again. Deep breath, followed by another. Reality started to turn back to normal and Fluttershy saw she was in front of the hospital with Applejack.
“You okay there Sugarcube? You hit your head pretty hard pardner.”
“Oh yes, thank you so much Apple-”
“Fluttershy! Daaahling!” Rarity called out from behind Fluttershy.
Putting her back into her heart attack.
“Oh Fluttershy dear, are you feeling alright?”
“Fluttershy here is just suffering from a bad cold. Poor thing couldn’t even jump on the wagon properly!” Applejack responded before Fluttershy could even open her mouth.
“A cold?!? Oh no no no! That won’t do! I know just the thing!”
“N-no!” Fluttershy weakly cried.
“A trip to the spa will make you feel worlds better! Much better than sitting in bed all day after taking some icky medicine!”
“But I…”
“Come now! Not a moment to lose! Bye Applejack!”
“Have fun now you two!” Applejack yelled as she waved goodbye.

Sadly, the whole way there Rarity chatted about the latest fashion hits and ideas for new dresses. Fluttershy was starting to black out again. When the massage part of the spa treatment came, Fluttershy found herself able to breathe at moments. Then the actual spa part happened.
“Rarity, I-”
“I know Darling, the water feels wonderful!”
“Ru..Rare..”
“Aren’t you glad you came here instead of going to that stuffy hospital?”
“Huu-hurrrkkk…”
“I know exactly how you feel dear.”
After Rarity put on her mud mask. She started to sit back and relax. Giving up on explaining, Fluttershy tried to quietly sneak out of the spa.
*THUNK*
“Fluttershy darling? Everything alright?”
“Huuun-hnnngh...Yes…”
“Alright dear, you tell me if you need anything.”
Fluttershy dragged herself out of spa building and worked her way to the hospital building as fast she could-
“HEYA FLUTTERSHY!”
Heart attack gone-
“I saw you dragging yourself across the ground and thought ‘Huh, that’s strange!’ until I realize *GAAAAAASP!’ SHE’S PLAYING A GAME!!!”
Heart attack back-
“So then I thought ‘I wanna play too!’ So I walked up to you and said-Hey! Your face is all blue! Are you pretending to be Rainbow Dash!?! THAT’S SO COOL!”
Gone.
“Oh! Oh! I know! Are you trying to see how long you can hold your breath?!? I’ll play too! HWUUUUUAAAAAAGHHH!!!”
Back.
Three feet. Three more feet and she would be in the hospital. Maybe Pinkie could-
“OH! Cupcakes are done! Good luck with your heart attack Fluttershy!”
And just like that Pinkie vanished. Two feet. Two more feet.
A parade, with Celestia and Twilight riding on top started coming down the street. With Fluttershy in the middle of the road. Crawling. Slowly. One foot.
*THUNK*
“Did you feel that Twilight?” Celestia asked.
“No, what is it Princess?” Twilight responded with a cheerful smile. Today was wonderful. She was absolutely sure on a day like this nothing could possibly go wrong.
“Hmm, must have been my imagination.” Celestia mused.
...T-two inches… Just...one more...inch…
The hospital door slammed open, smashing into Fluttershy, fixing her heart. Applejack and Applebloom walking out of it.
“Just in time for the parade!” Applejack beamed!
“I hope Fluttershy feels better. I bet she was happy to see Twilight and the Princess pass by!”
Applejack and Applebloom trotted towards the parade. The door slowly closed. And then slammed into Fluttershy again.
Giving her a heart attack.
Angel was sure Fluttershy had come here, after the way she limped out of the door. With a shrug, he made his way back home. Fluttershy weakly pushed the door open. And limped to the front desk.
“G-good afternoon. If you could please help me, I’m having a heart attack. That is, if you don’t mind…”
Nurse Redheart looked up at her.
“You’re having a heart attack?”
“Yes.”
“Right now?”
“Yes.”
“For how long now?”
“U-um… I think an hour? Maybe?..”
Nurse Redheart stared at Fluttershy for a good few seconds.
“Mare, if you’re having a heart attack, I think you would be in a bit more distress."
"O-oh."
"I think you might just be having heart burn."
"Oh, if you say so..."
With a snort, Redheart went back to eating her lunch.
"Look, if you are currently having a heart attack, I’ll quit my job and shove this banana up myself at your funeral. Now go home.”
---
Redheart, formally known as Nurse Redheart, walked towards the funeral procession. As she came close, a banner overhead saying 'SORRY THAT YOU DIED FROM YOUR HEART ATTACK FLUTTERSHY PARTY.' slowly shook from the gentle breeze. All of her friends were distraught. Ranging from crying to staring at the casket with dead eyes. Slowly, one by one. All her friends and family came up to say their peace. As the last one finished. Redheart slowly made her way up to the casket. Next to it was her grave.
'Fluttershy. She died how she lived. Too polite for her own good. R.I.P in peace.'
...R.I.P means Rest In Peace. It's saying Rest In Peace In-now is not the time for that.
With a stoic mask that could only be rivaled by Celestia, Redheart walked up to the mic and quietly spoke.
“...I am sorry. I am so, so sorry...for what you’re about to see.”
She pulled out a banana.
