Infection in permanent circulatory support: experience from the REMATCH trial
Summary
Left ventricular assist devices (LVADs) improve survival in end-stage heart failure patients. However, infections remain a significant cause of death and illness, highlighting the need for infection reduction strategies in LVAD recipients.
Area of Science:
- Cardiology
- Medical Devices
- Infectious Disease
Background:
- Infection is a major complication impacting morbidity and mortality in patients with end-stage heart failure.
- The REMATCH Trial provides critical data on device-related infections in Left Ventricular Assist Device (LVAD) recipients.
Purpose of the Study:
- To analyze infection incidence and outcomes in the REMATCH Trial.
- To identify strategies for reducing device-related infections and their impact on LVAD therapy.
Main Methods:
- Prospective randomized trial comparing LVADs to optimal medical management (OMM).
- Infection variables included sepsis, adverse events, and site/device infections.
- Comparative analysis of event incidence, prevalence, and time-dependent trends between groups.
Main Results:
- LVADs significantly improved survival compared to OMM (47% risk reduction in death).
- LVAD recipients had a higher aggregate adverse event rate (RR 2.29).
- Sepsis significantly reduced survival in LVAD patients; the risk peaked within 3 weeks post-implantation.
Conclusions:
- Permanent LVAD implantation enhances survival but carries substantial infection-related risks.
- Reducing infections is crucial to improve survival and decrease morbidity in LVAD recipients.
- Optimizing the risk-benefit profile of LVAD therapy necessitates effective infection control measures.
