Conclusions: These results show that anorexia nervosa is associated with left ventricular systolic dysfunction, which is related with the reduction of cardiac mass. Tissue Doppler imaging can give useful information in the identification of regional left ventricular dysfunction, in addition to traditional parameters. D 2004 Elsevier Ireland Ltd.

The Value of Using Pulsed Tissue Doppler Mitral Annulus
In a recent meta-analysis, all available studies of regional left ventricular function in patients with ischemic left ventricular dysfunction before and after revascularization were pooled . This analysis confirmed and extended the findings of the previous pooled analysis by the same group . In general, the

Left ven-tricular systolic function (LVSF) was assessed through ejection fraction (EF). Left ventricular systolic function impairment was defined as EF < 50%, systolic diameter (LVSD) and diastolic diameter (LVDD), wall thickness, regional assynergies (RA), diastolic function (E and A waves and transmitral flow ratio, defined as normal, type
Coronary microvascular function is independently associated
Doppler echocardiography was performed that included pulsed tissue Doppler of the mitral annulus and CFR of the left anterior descending artery (induced by adenosine 0.14 mg/kg/min). The ratio of mitral velocity to early diastolic velocity of the mitral annulus (E/e′) was used as a surrogate marker of diastolic function.
