BACKGROUND: Weight alterations post cardiac transplant (CT) frequently occur and increase the risks of secondary diseases. OBJECTIVE: This study aimed at determining the impact of weight variability on serum levels of glucose, triglycerides, total cholesterol and its fractions of cardiac transplant patients. METHODS: This was a retrospective documental study held with 82 patients submitted to CT between October, 1997 and December, 2005 in Ceará, Brazil. 83% were male and the average age was 45.06±12.04 years. The studied variables were: biopathology profile, the weight and the body mass index (BMI) related to the biochemical-metabolic alterations and to the survival. Data were described using frequencies, measures of central tendency, t-Student test and Pearson correlation coefficient. RESULTS: The average global BMI increased from 23.77±3.68kg/m² before CT to 25.48±3.92kg/m² on the first year and to 28.38±4.97kg/m² on the fifth year. The patients with overweight/ obesity (IMC > 25 kg/m²) presented average glucose mean levels, total cholesterol, low-density lipoprotein (LDL) and triglycerides higher than the patients with eutrophy/ malnutrition (IMC < 25 kg/m²). CONCLUSION: There was a significant direct relation between nutritional state and weight variability on the metabolic profile of cardiac transplant patients.
