New drug aims to protect hearts after attack
NCT ID NCT03470441
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new medicine called FDY-5301 in 120 people having a severe heart attack (STEMI). Participants received either the drug or a placebo during a procedure to open blocked arteries. The main goal was to see if the drug could reduce dangerous heart rhythm problems and limit heart damage. The trial has been completed, and results will help decide if further testing is needed.
