Comparison of Left Ventricular Diastolic Parameters Between Patients With and Without Significant Mitral Regurgitation

Kaohsiung Journal of Medical Sciences, 2010
Mitral regurgitation (MR) can affect left ventricular diastolic parameters because of interference with regurgitation flow. This study compared left ventricular diastolic parameters between patients with and without significant MR.

Low‐dose digoxin improves cardiac function in patients with heart failure, preserved ejection fraction and atrial fibrillation – the RATE‐AF randomized trial

European Journal of Heart Failure, Volume 27, Issue 12, Page 2869-2878, December 2025.
Summary of the change in left ventricular systolic and diastolic parameters from baseline to 12 months in patients with permanent atrial fibrillation (AF) and a left ventricular ejection fraction (LVEF) ≥50%. P‐values indicate the significance of the adjusted mean difference of the parameters at 12 months between the beta‐blocker and digoxin arm. E/e′,

Cardiac Time Intervals Measured by Tissue Doppler Imaging M‐mode: Association With Hypertension, Left Ventricular Geometry, and Future Ischemic Cardiovascular Diseases

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundWe hypothesized that the cardiac time intervals reveal reduced myocardial function in persons with hypertension and are strong predictors of future ischemic cardiovascular diseases in the general population.

Quantitative assessment of regional peak myocardial acceleration during isovolumic contraction and relaxation times by tissue Doppler imaging [PDF]

Heart, 2005
Objective: To examine regional wall acceleration and its relation to relaxation. Study design: 8 sheep were examined by tissue Doppler ultrasound imaging (VingMed Vivid FiVe) in apical four chamber views to evaluate the left ventricular wall divided into six segments and the mitral annulus in two ...

Consideration on Estimating Mean Pulmonary Artery Pressure Using Early Diastolic Pulmonary Regurgitation Velocity

Sonography, Volume 12, Issue 4, Page 425-429, December 2025.
ABSTRACT Estimation of mean pulmonary artery pressure (mPAP) using peak velocity of pulmonary regurgitation (PR) obtained via continuous‐wave Doppler echocardiography has been applied in clinical practice. However, the theoretical basis for this method and whether to include right atrial pressure (RAP) in the calculation vary across reports, with no ...

Left ventricular myocardial performance index in prediabetic patients without coronary artery disease

The Egyptian Journal of Internal Medicine, 2021
Background Prediabetes is considered a major risk factor for diabetes mellitus (DM), leading to microvascular and cardiovascular disorders. Myocardial performance index (MPI) is a non-invasive Doppler method for the determination of global ventricular ...

Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

Advanced Science, Volume 12, Issue 43, November 20, 2025.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

Development of an efficient mice model of cancer‐associated cardiac cachexia

Animal Models and Experimental Medicine, Volume 8, Issue 11, Page 1960-1970, November 2025.
This work establishes a preclinical framework for targeting ubiquitin pathways to mitigate the morbidity of cancer‐related cardiopathy. Our integrated approach delineates a hierarchical progression from subcellular dysfunction to macroscopic cardiac deterioration. These findings mechanistically link tumor‐induced cachexia to cardiac dysfunction through
