Table 3.
Clinical outcomes in 347 HT recipients during the first 3 years after HT surgery by 2 post-HT weight groupsa: Group 1 = non-overweight; Group 2 = overweight.
| Outcome | Group 1 (N = 108) | Group 2 (N = 239) | χ2b | Fc | Pd |
|---|---|---|---|---|---|
| CAV | 5.6% | 18.0% | 14.84 | .002 | |
| Stroke | 10.2% | 5.4% | 2.91 | .088 | |
| Severe renal dysfunctione | 18.5% | 13.4% | 6.76 | .009 | |
| New-onset steroid-induced diabetes | 10.2% | 14.2% | 5.11 | .024 | |
| Lymphoma | 7.4% | 1.7% | 7.64 | .006 | |
| Number of days re-hospitalized after HT discharge | 36 ± 44 | 33 ± 36 | 3.37 | .010 | |
| Number of treated acute rejections | 3.1 ± 3.1 | 3.7 ± 3.6 | 4.00 | .003 | |
| Number of IV-treated infections | 2.3 ± 2.9 | 1.9 ± 2.5 | 1.68 | .155 |
CAV, cardiac allograft vasculopathy; HT, heart transplant; IV, intravenous.
Weight groups based on mean post-transplant BMI (body mass index = kg/m2): Group 1 (non-overweight) = BMI <25 (range = 16–24, mean = 22, SD = 1.9); Group 2 (overweight) = BMI ≥ 25 (range = 25–40, mean = 29, SD = 3.2).
Logistic regression (χ2) was used for dichotomous outcomes (%) and adjusted for covariates of patient gender, patient age at HT, and donor age.
MANCOVA (F) was used for continuous outcomes (mean ± standard deviation) and adjusted for covariates of patient gender, patient age at HT, and donor age.
Significance determined at P ≤ .025.
Defined as a serum creatinine >2.5 mg/dl or a diagnosis of renal failure or on dialysis.9
