The Myocardial Performance Index in Patients with Aortic Stenosis

Echocardiography, 2002
Objectives: This study was designed to determine the effect of chronic afterload on a Doppler‐derived myocardial performance index (MPI) combining both systolic and diastolic left ventricular dysfunction. Methods: The study included 36 patients with a diagnosis of aortic stenosis and 36 normal subjects. Doppler‐derived myocardial performance index (MPI)

Influence of weight loss on myocardial performance index

Heart and Vessels, 2006
Obese patients may have a phase of asymptomatic left ventricular dysfunction. A combined myocardial performance index (MPI) has been demonstrated to be a useful index to estimate left ventricular function and to predict the prognosis of patients with heart failure. The objective of the study was to determine the influence of weight loss on MPI. A total

Age dependency of the Tei index of myocardial performance

Journal of the American Society of Echocardiography, 2004
Despite its clinical use as a sensitive measure of left ventricular performance, little is known about whether the Tei index is influenced by aging. We determined the Tei index in 141 subjects without cardiovascular disease (age 16-78 years). There were statistically significant variations in ejection time, isovolumic relaxation time, and the Tei index

Tei index (myocardial performance index) and cardiac biomarkers in dogs with parvoviral enteritis

Research in Veterinary Science, 2012
Tei index (myocardial performance) and cardiac biomarkers were evaluated in dogs with parvoviral enteritis (PVE). Tei index was calculated as isovolumic contraction time plus isovolumic relaxation time divided by ejection time.

Value of the Doppler Index of Myocardial Performance in the Early Phase of Acute Myocardial Infarction

Journal of the American Society of Echocardiography, 2000
Prospective assessment of a nongeometric Doppler-derived index of combined systolic and diastolic myocardial performance was performed in 64 patients with acute myocardial infarction (MI) within 1 hour after their arrival to the hospital and in 39 age-matched healthy subjects.

Myocardial performance index in patients with dipper and nondipper hypertension

Blood Pressure Monitoring, 2014
The aim of this study was to evaluate the relationship between left ventricular (LV) myocardial performance index (MPI) and nondipper pattern in hypertensive patients.Between June 2012 and November 2012, patients admitted to the Cardiology Department of Düzce University Faculty of Medicine and diagnosed previously with essential hypertension were ...

Serial evaluation of myocardial function using the myocardial performance index in Kawasaki disease

World Journal of Pediatrics, 2018
Kawasaki disease (KD) is known as systemic vasculitis, and more than half of the patients with KD have myocarditis, which can induce ventricular dysfunction. In this study, we evaluate left ventricular (LV) dysfunction in patients with KD based on the myocardial performance index (MPI) using pulse Doppler (PD) and tissue Doppler imaging (TDI), from the

Assessing the development of fetal myocardial function by a novel Doppler myocardial performance index

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Doppler-derived myocardial performance index are used to assess aspects of systolic and diastolic function in adult as well as fetal heart. The Tei Index (TI) is a useful and non-invasive tool. The aim of this study was to determine normal values of fetal left ventricular (LV) TI in early (16-32 weeks) and late trimester (35-41 weeks) fetuses and to ...

The Influence of Heart Rate on the Doppler-Derived Myocardial Performance Index

Journal of the American Society of Echocardiography, 2000
The Doppler-derived myocardial performance index (MPI), defined as the sum of isovolumetric contraction and relaxation durations divided by ejection time and reflecting both systolic and diastolic myocardial function, has been found to be related to morbidity and mortality in cardiac diseases.

Beat‐to‐beat change in ‘myocardial performance index’ related to load

Acta Anaesthesiologica Scandinavica, 2007
Background:  This study was designed to assess the relationship of the ‘myocardial performance index’ (MPI) to the beat‐by‐beat change in pre‐load with static or unchanged contractile status.Methods:  Eight anesthetized juvenile pigs were studied using direct measurement of the left ventricular pressure and volume.
