Early detection of cardiac dysfunction: Use of the myocardial performance index in patients with anorexia nervosa

Overview: Patients with anorexia nervosa have functional cardiac abnormalities secondary to their nutritionally depleted state. These abnormalities include decreased left ventricular (LV) mass and varying degrees of LV systolic dysfunction. Assessment of LV diastolic function and quantitative assessment of right ventricular function are not routinely performed. The myocardial performance index (MPI) is a relatively new, simple, quantitative measure of global myocardial function. The purpose of this study was to evaluate left and right ventricular function in 13 patients with anorexia nervosa with the MPI and compare it to more commonly used echocardiographic measures of ventricular function.
