BACKGROUND: Longer term quality of life (QOL) outcome in patients who have had a left ventricular assist device (LVAD) explanted due to myocardial recovery (bridge to recovery, BTR) remains uncertain. This study evaluates the QOL of those patients and compares them to bridge-to-transplant (BTT) and transplanted (Tx) patients.
METHODS: Anonymized QOL Short Form (SF)-36 questionnaires were sent to a total of 72 patients, including: 14 BTR patients (3.6 +/- 1.9 years since LVAD removal); 29 BTT patients (3.3 +/- 2.3 years since transplantation); and 29 Tx patients (3.8 +/- 0.6 years since transplantation).
RESULTS: Questionnaires were returned by 78.6%, 79.3% and 56.7% of patients from the BTR, BTT and Tx groups, respectively. In all but two of the domains of the SF-36 questionnaire, scores were significantly better in the BTR group compared with the BTT and Tx groups. Analysis of the two main dimensions and the total SF-36 score between the three groups showed that: (i) physical health dimension tended to be better in BTR (71.9 +/- 21) vs BTT (64.5 +/-23.2) and Tx (41.4 +/- 48) groups (p = not statistically significant [NS]); (ii) mental health dimension was better in both BTR (78 +/- 16.1) and BTT (71.4 +/- 21.1) groups compared with the Tx group (39.4 +/- 44, p<0.05); and (iii) total SF-36 score was significantly higher in the BTR and BTT groups compared with the Tx group (76.8 +/- 17.6 and 69 +/- 21.1 vs 41.4 +/- 48, p = NS).
CONCLUSIONS: BTR patients appear to have better QOL than both BTT and Tx patients. In addition, BTT patients seem to have a better QOL compared with Tx patients, suggesting that placement of ventricular assist devices could improve the physiologic outcome for transplanted patients.
