SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

The Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Myocardial performance index and cardiovascular diseases

Echocardiography, 2023
AbstractThe Myocardial Performance Index (MPI), also known as the Tei Index, is a measure of the overall performance of the heart that takes into account both systolic and diastolic function. It is a non‐invasive echocardiographic index that provides information about the efficiency of the heart's pumping action. The MPI is a useful tool for evaluating

[Myocardial performance index].

Anadolu kardiyoloji dergisi : AKD = the Anatolian journal of cardiology, 2008
Myocardial performance index (MPI) is a numeric value, which could be obtained by using cardiac time intervals. This numeric value is defined as the sum of isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) divided by ejection time (ET) and could be calculated for each ventricle individually.

Myocardial Performance Index in Evaluation of Acute Right Ventricular Myocardial Infarction

Echocardiography, 2004
The goal of this study was to evaluate the role of Doppler time interval‐derived myocardial performance index (MPI) in the setting of acute right ventricular myocardial infarction (RVMI). Inferior myocardial infarction is accompanied by RVMI in over a third of cases. We do not have easily applicable noninvasive tools for reliably quantifying the right

Index of myocardial performance after early phase of myocardial infarction in relation to its location

Journal of the American Society of Echocardiography, 2004
To define the degree of heart derangement in recent myocardial infarction (MI) occurring in different wall locations of myocardium, we echocardiographically evaluated left ventricular volumes, ejection fraction, wall-motion score index, isovolumetric contraction and relaxation time, ejection time, and index of myocardial performance in 74 patients with

Myocardial performance index in fetal anemia

Prenatal Diagnosis, 2014
AbstractObjectiveThe objective of the study was to examine the correlation between fetal myocardial performance index (MPI) and hemoglobin (Hb) levels.MethodsIt is a prospective study involving singleton pregnancies at risk of fetal anemia as a result of maternal anti‐D alloimmune disease. Right and left ventricle (LV) MPIs were evaluated by ultrasound

Effects of hemodialysis on myocardial performance index

Advances in Therapy, 2004
The myocardial performance index (MPI) reflects global ventricular function. Chronic hypervolemia and uremia may negatively affect the myocardium of both ventricles. The aims of this study were to investigate how chronic renal failure (CRF) affects biventricular MPI and to determine whether preload reduction by hemodialysis (HD) affects left ...

Kidney function and the prognostic value of myocardial performance index

The International Journal of Cardiovascular Imaging, 2021
A decreased glomerular filtration rate (GFR) is a risk factor for cardiovascular disease even after adjustment for conventional risk factors. The myocardial performance index (MPI) is defined as (isovolumetric relaxation time (IVRT) + isovolumetric contraction time (IVCT))/ejection time (ET).
