New Blood Score Could Distinguish Heart Attacks From Broken Heart Syndrome
StudyFinds • • health
Key Points:
- A new diagnostic tool called the BioTAK score uses five blood markers and patient sex to reliably distinguish takotsubo syndrome ("broken heart syndrome") from heart attacks before invasive procedures are performed.
- Takotsubo syndrome, which mimics heart attack symptoms but involves stress-induced heart muscle dysfunction without artery blockage, accounts for 1%-4% of suspected heart attack cases and predominantly affects postmenopausal women.
- The BioTAK score demonstrated strong accuracy in two large Swiss patient groups, achieving near-perfect ability to rule out or confirm takotsubo syndrome, potentially reducing unnecessary invasive catheterizations.
- Key biomarkers in the score reflect different biological processes between takotsubo syndrome and heart attacks, including heart muscle stress, anxiety response, artery plaque instability, and cholesterol levels.
- While promising, the BioTAK score requires further real-world testing to determine its impact on patient outcomes, and it is not intended to replace clinical judgment but to aid faster, less invasive diagnosis.
