Abstract

Background: Current treatment options for end-stage heart failure, such as transplantation, can be limited by obesity guidelines. Mechanical devices such as Left Ventricular Assistive Devices (LVAD) can bridge heart failure patients to transplantation, however, after implantation; some patients may experience weight gain that precludes them from transplantation. Therefore, the objective of this study was to evaluate weight changes after the implantation of an LVAD.

Methods: A retrospective review of 130 patients receiving an LVAD were divided into two groups based on BMI at the time of implantation: obese (>30 kg/m2) and non-obese (/m2). Patients were evaluated at three time points post LVAD implantation: 3, 6, and 12 months for changes in weight and BMI.

Results: The mean BMI of the overall cohort at the time of LVAD implantation was 30.3 kg/m2. Patients who were not classified as obese at the time of LVAD implementation had a significant increase in BMI (2.1 kg/m2, p<0.001)

Conclusion: Weight gain after LVAD implementation is more likely in patients who are non-obese at the time of LVAD evaluation; however, obese subjects remained unlikely to lose weight one year post implantation.
