Most people first hear the word ātroponinā after they, or someone they love, ends up in the ER š„
And when a doctor says, āYour troponin is elevated,ā it can sound terrifying.
So what is troponin?
Troponin is a protein found inside heart muscle cells. When the heart is injured, stressed, inflamed, or not getting enough oxygen, troponin can leak into the bloodstream. ā¤ļø
Thatās why doctors often check troponin when someone has:
⢠Chest pain
⢠Shortness of breath
⢠Fainting
⢠An abnormal EKG
⢠Symptoms concerning for a heart attack
But hereās the important part:
An elevated troponin does NOT always mean heart attack.
It simply tells doctors: āSomething may be stressing the heart.ā
Troponin can also rise from:
⢠Severe infection
⢠Heart failure
⢠Kidney disease
⢠Blood clots in the lungs
⢠Very fast heart rhythms
⢠Broken heart syndrome, also called Takotsubo cardiomyopathyš (And yes, broken heart syndrome is real)
Troponin is not a panic number. Itās a clue!š©ŗ
Doctors use it alongside symptoms, EKGs, medical history, and other testing to figure out whatās really going on.
At HeartHero, we believe heart education should be simple enough for everyone to understand, because faster understanding can lead to faster action when every second mattersā”
