Left Ventricular Dysfunction Associated With Brain Death: Results From the Donor Heart Study

LV dysfunction associated with brain death occurs in many potential heart donors and is sometimes reversible.

- Participants
- 4,333 donors
- Outcome

Main finding
As reported in the abstract
Left ventricular (LV) dysfunction
493
13%
Observational data: associations, not effects.
Further findings
| Outcome | Normal LV function | Reversible LV dysfunction | Nonreversible LV dysfunction |
|---|---|---|---|
| Donor heart acceptance for transplant | Sixty percent | 56% | 24% |
Reversibility of LV dysfunction on second TTE · 24±6 hours
- Reversible LV dysfunction among donors with second TTE (n=224)
- 130 (58%)
Factors associated with LV dysfunction
- LV dysfunction associated with younger age, underweight, and higher NT-proBNP and troponin levels
Recipient 1-year survival
- Donor LV dysfunction, reversible or not, not associated with recipient 1-year survival
