OBJECTIVES: Anorexia nervosa is a life-threatening eating disorder, with significant risk for sudden death due to severe cardiac complications. The aim of this prospective study was to evaluate the cardiac abnormalities in female adolescents with anorexia nervosa and to examine the long-term results and reversibility of the detected cardiac abnormalities. METHODS: We prospectively studied eleven female adolescents (13.5-17 years old) with anorexia nervosa diagnosed according to DSM IV criteria. On admission they were all on a weight-losing course with a mean body mass index of 13.71 +/- 1.54 (11.38-17.05) kg/m2. The mean follow-up duration was 2.45 +/- 1.17 (1-4.5) years. All patients reached normal weight after treatment. The control group was composed of 12 healthy, age-matched, adolescent girls of normal weight. The patients with anorexia nervosa and the control group underwent a complete clinical examination, electrocardiographic and echocardiographic evaluations. These evaluations were repeated one year after refeeding. RESULTS: Patients with anorexia nervosa had a lower heart rate and blood pressure than the control group and they increased to normal levels as found in the control group after refeeding. QT and QTc were significantly longer and R wave amplitudes in V6 were significantly lower in the patients with anorexia nervosa than in the control group. QT and QT'c dispersions were significantly greater in anorexia nervosa patients compared to the control group. Left ventricular mass and left ventricular mass index were significantly lower in the anorexia nervosa group. One year after refeeding, there was a significant decrease in QT, QTc, QTd and QTcd. Although in anorexia nervosa patients, R wave amplitudes in V6 increased after refeeding; they did not reach the levels found in the control group. Control echocardiograms of anorexia nervosa patients after refeeding showed an increase in LV diameters and cardiac mass. There was a strong correlation between QT dispersion and left ventricular mass index. CONCLUSIONS: The adolescent girls with anorexia nervosa had significant structural and functional cardiac abnormalities in comparison to the control group. All these abnormalities were reversible except low R wave amplitude in V6.
