Impact of pre-existing left ventricular dysfunction on kidney transplantation outcomes: implications for patient...

End-stage kidney disease patients with decreased left ventricular ejection fraction (EF) are often denied kidney transplantation (KT) for fear of poor graft and patient survival.

We retrospectively studied all patients who underwent KT at our center between 2001 and 2005 to determine the impact of low EF on outcomes post KT. Low EF was defined as <50% EF by noninvasive cardiac imaging. Follow-up was for 1 year post KT. Outcomes assessed included hospitalization for congestive heart failure (CHF), cardiac events, and renal allograft and patient survival.

Among 254 patients, 37 had low EF (study group) and 217 had normal EF (≥50%; control group). Post KT, the low EF group had a significantly higher rate of hospitalization for CHF. No significant difference was noted in the rate of cardiac events, graft loss, GFR, and all cause death at 12 months post KT.

Patients with low EF should not be excluded from transplantation, given favorable outcomes.
