Primary outcomePrimary: The Change in Platelet Aggregation Measured by the Accumetrics (VerifyNow P2Y12) Assay Between Baseline and Each Antiplatelet Medication — 66.4; 156.2 PRU (P2Y12 reactivity units) — p=<0.05

No publication linked
No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The investigators aim to determine if patients with systolic heart failure treated with prasugrel achieve greater platelet inhibition compared to those treated with clopidogrel.
