Comparing higher and lower doses of heparin for heart procedures

A Randomized Trial of Higher vs. Lower Dose Heparin for PCI

Not applicable Interventional Population Health Research Institute · NCT04049591

This study is testing whether using a higher dose of heparin during heart procedures helps patients do better than using a lower dose.

What this trial studies

This trial investigates the effects of higher dose heparin (100 U/kg) versus lower dose heparin (70 U/kg) in patients undergoing elective percutaneous coronary intervention (PCI). It employs a multicenter, randomized, registry-based, cluster crossover design to assess outcomes such as death, myocardial infarction, and target vessel revascularization. The study aims to determine which dosing strategy is more effective in improving patient outcomes during PCI procedures.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for elective percutaneous coronary intervention.

Not a fit: Patients under 18 years old or those requiring chronic total occlusion PCI may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved safety and effectiveness of heparin use during heart procedures.

How similar studies have performed: Other studies have explored heparin dosing in PCI, but this specific comparison of higher versus lower doses in a registry-based design is relatively novel.
