Cardiac output and regional myocardial contraction in anorexia nervosa
1988
Abstract The study measured cardiac output and assessed regional myocardial contraction in 14 patients with anorexia nervosa, some of whom also had bulimia, and in 15 controls. The experimental and control groups were not significantly different in age or body surface area ( p = > 0.05). To evaluate regional myocardial contraction, 12 of 14 anorexia nervosa-bulimia (ANB) patients were studied in the acute phase and once serially at a mean interval of 1.5 years by assessing the movement of each left ventricular wall segment toward the center of the ventricle as imaged in the precordial short axis. Cardiac output was measured in the ascending aorta by pulsed Doppler for control subjects and for 13 ANB patients. Regional myocardial contraction was normal for all controls, but eight of 14 ANB patients showed regional myocardial contraction abnormalities. Between studies, four of these eight demonstrated improved regional myocardial contraction, three remained unchanged, and one was worse. Mean cardiac output was markedly reduced in ANB patients (2.6 L/min) compared to controls (4.5 L/min) ( p = p = p =
