Influence of body mass index on survival and length of hospital stay in heart transplantation versus left ventricular assist device recipients

    Authors

    Abstract

    Purpose: There is a substantial amount of data demonstrating the influence of body mass index (BMI) on outcomes of patients after heart transplantation (HTx) or left ventricular assist device (LVAD) implantation. However, no direct comparisons were made between these two modalities of advanced heart failure treatment in a specific population in terms of pretreatment BMI. (1-3) Patients and Methods: We retrospectively studied 90 consecutive HTx (67 male, mean age 51.9±13, median follow-up 20.8 months) and 32 consecutive LVAD (27 male, mean age 58.3±8, mean follow-up 13.1 months) patients from our centre in the period from January 2010 to December 2014. The patients were categorized in groups according to pretreatment BMI: non-overweight patients (BMI 2 | 38 | 12 | | ≥25 kg/m2 | 52 | 20 | Figure 1. Kaplan-Meier survival curves for body mass index groups in relation to different treatment options. Figure 2. Modified Kaplan-Meier curves representing length of hospital stay for body mass index groups in relation to different treatment options. Conclusion: Non-overweight patients in our cohort demonstrated better survival with HTx than LVAD treatment. No influence of BMI on length of hospital stay was shown between the HTx and LVAD treatment groups.
