ABSTRACT
BACKGROUND: Weight changes frequently occur after cardiac transplantation (CT) and increase the risk of secondary diseases. OBJECTIVE: To determine the impact of weight variation on serum levels of glucose, triglyceride, total cholesterol, LDL, HDL and triglycerides of cardiac transplant patients. METHODS: Retrospective documentary study conducted with 82 adult patients undergoing CT between October 1997 and December 2005 in the State of Ceara, Brazil. A total of 83% of the patients were male and the mean age was 45.06+/-12.04 years. The variables studied were biopathological profile, weight, and body mass index (BMI) in relation to biochemical and metabolic changes. Data were described using frequencies, measures of central tendency, Student's t test and Pearson's correlation coefficient. RESULTS: The mean overall BMI increased from 23.77+/-3.68 kg/m2 prior to CT, to 25.48+/-3.92 kg/m2 in the first year and to 28.38+/-4.97 kg/m2 in the fifth. Overweight/obese patients (BMI > or = 25 kg/m2) showed mean values of glucose, total cholesterol, low-density lipoprotein (LDL) and triglycerides higher than those of normal-weight/underweight patients (BMI < 25 kg/m2). CONCLUSION: There was a significant direct relation between nutritional state and weight variability on the metabolic profile of cardiac transplant patients.

FUNDAMENTO: As alterações de peso após o transplante cardíaco (TC) freqüentemente ocorrem e aumentam os riscos de doenças secundárias. OBJETIVO: Determinar o impacto da variabilidade do peso nos níveis séricos de glicose, triglicérides, colesterol total e frações dos pacientes transplantados cardíacos. MÉTODOS: Estudo retrospectivo documental realizado com 82 pacientes adultos submetidos a TC entre outubro de 1997 e dezembro de 2005 no Ceará, sendo 83 por cento do sexo masculino e a idade média de 45,06±12,04 anos. As variáveis estudadas foram o perfil biopatológico, o peso e o índice de massa corporal (IMC) relacionadas às alterações bioquímico-metabólicas. Os dados foram descritos usando freqüências, medidas de tendência central, teste t de Student e coeficiente de correlação de Pearson. RESULTADOS: A média global do IMC aumentou de 23,77±3,68kg/m² antes do TC, para 25,48±3,92kg/m² no primeiro ano e para 28,38±4,97kg/m² no quinto. Os pacientes com sobrepeso/obesidade (IMC > 25 kg/m²) apresentaram valores médios de glicose, colesterol total, lipoproteína de baixa densidade (LDL) e triglicérides maiores que os pacientes com eutrofia/desnutrição (IMC < 25 kg/m²). CONCLUSÃO: Houve uma relação direta e significativa entre o estado nutricional e a variabilidade de peso no perfil metabólico de pacientes transplantados cardíacos.
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 percent 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.
