Background |
Cardiac cachexia and low serum albumin levels are poor prognostic signs in advanced heart failure, while overweight patients or patients who gain weight after treatment have more favourable outcomes. Weight gain following LVAD implantation is common, while the dynamic changes in body mass or serum proteins have not been studied adequately. Our aim was to study short-term changes in serum albumin, total protein and body weight following LVAD implantation and to compare these changes with heart failure patients treated medically.
Materials and Methods |
A total of 15 patients scheduled for LVAD implantation and 15 patients receiving medical treatment were prospectively enrolled. Anthropometric and laboratory data for the patients were obtained at baseline and at first and sixth months after LVAD implantation.
Results |
Anthropometric, demographic and clinical characteristics between two groups were similar at baseline. Both serum albumin (3.59±0.71 vs. 4.17±0.46g/dl, p=0.01) and total protein (6.45±0.80 vs. 7.12±0.35g/dl, p<0.01) levels were significantly lower in LVAD group at baseline. Both total protein and serum albumin levels increased significantly in LVAD group (final total protein 7.60±0.62g/dl and serum albumin 4.20±0.46g/dl; p<0.01 for both), while there was a nonsignificant small decrease in serum albumin in medical group. The change in serum albumin, but not total protein was significantly different between LVAD and medical groups at the sixth month. Body weight initially decreased in LVAD group at first month but was nonsignificantly higher compared to baseline and medical group at the sixth month. There was a moderate correlation between the percentage weight gain and percentage increase in serum albumin in LVAD group at six months (r=0.44).
Conclusions |
In suitable patients with advanced heart failure, LVAD treatment can correct hypoalbuminaemia associated with heart failure within six months after implantation.
