Doppler-Derived Myocardial Performance Index in Healthy Children in Shiraz
Background: Assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. Ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. Objective: A myocardial performance index (MPI) or Tei index has been developed for adult...
متن کاملRelationship Between Tei Index and PEP-Derived Myocardial Performance Index in Sinus Rhythm
The goal of this study was to evaluate the preejection time (PEP)-derived myocardial performance index (MPI) in hypertensive (HT) patients with sinus rhythm and its relationship to the classic Tei index. One hundred five patients were enrolled in the study (65 HT and 40 control subjects). The mean age of all patients was 50.5 ± 15 years and 60% were female. Echocardiography was performed on all...

of classical echocardiographic indexes for the estimation of systolic and diastolic left ventricular (LV) function. The ejection fraction (EF, an index of systolic function) and LV volumes are subject to large errors when the ellipsoid shape of the heart becomes spherical. Age, rhythm and conduction disturbances, and changes in loading all affect the Doppler signal of transmitral flow, which is...

impairment of left ventricular (LV) systolic and diastolic dysfunction to various degrees. These functions are energetically and tightly coupled: 1) at the cellular level, since adenosine triphosphate is a substance essential for both active contraction and relaxation; 2) at the myocardial level, because regional wall motion asynchrony influences global LV diastolic function (contraction-relaxa...
