Brief Summary

Heart failure is a world epidemic. LVADs are increasingly used as they have demonstrated improved survival rates compared to optimal medical management. Improving outcomes have been seen with the newer LVAD technology, the HeartMate 3 (Abbott, Chicago, IL), however, hemocompatibility related adverse events, including thrombosis and bleeding, are still a major cause of morbidity and mortality. The recent ARIES trial showed that in patients with advanced heart failure treated with a HeartMate3 LVAD, avoidance of aspirin as part of an antithrombotic regimen, which includes vitamin K antagonist (VKA), is not inferior to a regimen containing aspirin, does not increase thromboembolism risk, and is associated with a reduction in bleeding events. This clinical investigation is a prospective, randomized, controlled study of advanced heart failure patients supports with the HeartMate3 for more then 3 months with two different antithrombotic regimens: VKA with and without aspirin. The objective of this investigation is to study the safety and efficacy of an antithrombotic regimen without antiplatelet therapy.

Outcome Measures

Primary Outcomes (1)

  • Number of survival free patients of any major hemocompatibility related adverse events.

    A Major Hemocompatibility Related Adverse Event is defined as: Stroke, Pump Thrombosis (suspected or confirmed), major non-surgical Bleeding (moderate or severe) (including intracranial bleeds that do not meet the stroke definition), Arterial Peripheral Thromboembolism. The events will be recorded and tallied per patient.

    1 year post implant

Secondary Outcomes (6)

  • Number of Non-surgical Major Hemorrhagic Events

Study Arms (2)

Warfarin without Aspirin

EXPERIMENTAL

Participants will only take Warfarin.

Drug: Warfarin

Warfarin and Aspirin

ACTIVE COMPARATOR

This is the control arm. Participants will take Warfarin and aspirin, which is the standard of care.

Drug: AspirinDrug: Warfarin

Interventions

81-100 mg, oral

Also known as: ASPIRIN® tablets
Warfarin and Aspirin

Warfarin dose will be adjusted per patient for a goal INR 2-3. The individualized daily dose could range anywhere from 0.5-2 mg to 5-7 mg. Oral.

Also known as: Vitamin K antagonist, COUMADIN
Warfarin and AspirinWarfarin without Aspirin
