Could a simple pill switch reduce heart risks after stent surgery?
NCT ID NCT07025148
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether switching from a standard blood thinner (clopidogrel) to a lower-dose version of another (prasugrel) can better control blood clotting in heart patients who have both high bleeding and high clotting risks after getting a stent. About 40 adults who have been on dual blood thinners for at least a month will be randomly assigned to either stay on their current medication or switch to the lower-dose prasugrel. The main goal is to measure how well the blood is thinned, not to directly assess heart attack or stroke prevention.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients with high bleeding risk (defined according to the ARC-HBR criteria) who have undergone PCI and are on maintenance treatment with DAPT, consisting of low-dose aspirin (81mg qd) with clopidogrel (75 mg qd) as part of standard of care for at least 30 days. * Age ≥18 years. * Provide written informed consent. Exclusion Criteria: * Prior cerebrovascular event. * PCI within 30 days. * Hemodynamic instability. * On treatment with any oral anticoagulant (vitamin K antagonists, dabigatran, rivaroxaban, apixaban, edoxaban) or chronic low-molecular-weight heparin (at venous thrombosis treatment, not for prophylaxis). * Hypersensitivity to Aspirin, Clopidogrel, or Prasugrel. * Known hematologic malignancies or thrombocytopenia (platelet count \<80x106/mL). * Known hemoglobinopathies or anemia (hemoglobin \<9 g/dL) * Pregnant and breastfeeding women \[women of childbearing age must use reliable birth control (i.e., oral contraceptives) while participating in the study\].
