The presence of malnutrition and cachexia in patients with congestive heart failure is well documented. ^1,2 Nutritional status also bears a significant influence on wound healing and immune function in surgical patients in general. Left ventricular assist devices (LVADs) have become an acceptable mode of bridge to transplantation for patients with end-stage heart failure. We propose to study the course of nutritional status in patients receiving LVAD support and correlate this with their clinical outcomes.

Patients and Methods

Ninety-nine patients undergoing LVAD implantation from January 1996 through February 2003 were retrospectively reviewed. Patients were evaluated according to 4 preoperative nutritional parameters: serum albumin level, total protein (TP) level, absolute lymphocyte count (ALC; white cell count x percentage lymphocytes), and body mass index (BMI). Each parameter was categorized as low or normal according to our patient population's value range: albumin, 3.5 to 5.3 g/dL; TP, 6.0 to 8.5 g/dL; ALC, 0.85 to 4.10 x 10³/mL³; and BMI, 20 to 25 kg/m².
