Half the heparin, less bleeding? new study tests safer heart surgery
NCT ID NCT00657475
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using half the usual dose of heparin during heart surgery (bypass or valve replacement) could reduce bleeding afterward. Heparin is a blood thinner used to prevent clots during surgery, but it can increase bleeding. The study involved 238 adults and compared the half dose to the standard dose, using a special mini heart-lung machine. The goal was to see if the lower dose could make surgery safer without raising the risk of clots.
