Aims: Early diastolic mitral annular velocity (e') obtained by tissue Doppler imaging (TDI) is widely used to evaluate left ventricular (LV) diastolic function based on the assumption that it reflects myocardial relaxation in the long-axis direction. In this study, we aimed to determine whether or not e' truly reflects early diastolic longitudinal myocardial relaxation, and which is the most useful for evaluating LV diastolic function among e' measured at the interventricular-septal annulus (IS-e'), that measured at the lateral annulus (LW-e') or their mean value (M-e').
Methods And Results: IS-e', LW-e', and M-e' were measured using colour TDI in 15 patients with hypertrophic cardiomyopathy, 13 patients with hypertension, and 19 control subjects. Using two-dimensional speckle-tracking imaging, early diastolic myocardial strain rates (SR(E)) were measured for the IS (IS-SR(E)), LW (LW-SR(E)), and entire LV myocardium (G-SR(E)). IS-e' was excellently correlated with IS-SR(E) (r = 0.90, P < 0.001); the correlation was better than that between LW-e' and LW-SR(E) (r = 0.75, P < 0.001). IS-e' and M-e' were well correlated with G-SR(E) (r = 0.88, P < 0.001 and r = 0.86, P< 0.001, respectively) and with LV early diastolic flow propagation velocity (FPV) (r = 0.77, P < 0.001 and r = 0.78, P < 0.001, respectively). The correlations of LW-e' to G-SR(E) (r = 0.80, P < 0.001) and FPV (r = 0.75, P < 0.001) did not reach this level.
Conclusion: IS-e' well reflected LV longitudinal myocardial relaxation and LV diastolic function, and was found to be more useful in evaluating LV diastolic function than LW-e'.

Independent risk factors for twin pregnancy adverse fetal outcomes before 28 gestational week by first trimester ultrasound screening.
World J Radiol
January 2025
Department of Ultrasound, Shanghai Changning Maternity and Infant Health Hospital, East China Normal University, Shanghai 200050, China.
Background: The incidence of multiple pregnancies has increased worldwide recently and women with a twin pregnancy are at higher risk of adverse outcomes compared with women with a singleton pregnancy. It is important to understand the risk factors for adverse fetal outcomes in twin pregnancy in order to guide clinical management.
Aim: To identify the independent risk factors, including maternal personal and family medical histories and first trimester ultrasound screening findings, for adverse fetal outcomes of twin pregnancy before 28 weeks of gestation.
Systematic Review and Meta-Analysis of 24-Hour Ambulatory Blood Pressure Monitoring in Pregnancy and Postpartum Periods.

Purpose: Early detection and management of hypertensive disorders during pregnancy and postpartum are essential. This systematic review and meta analysis aimed: (1) to examine the state of 24-hour ambulatory blood pressure (ABP) use, and (2) in a subset of studies, evaluate 24-hour ABP parameters in the prediction and identification of Hypertensive Disorders of Pregnancy (HDP).
Methods: A comprehensive literature search was conducted in March of 2022 for English language studies published after 2000.
Background: Household air pollution is a major contributor to cardiovascular disease burden in women in Sub-Saharan Africa. However, little is known about exposures during pregnancy or the effect of clean cooking interventions on postpartum blood pressure trajectories.
Methods: The Ghana Randomized Air Pollution and Health Study (GRAPHS) randomized 1414 non-smoking women in the first and second trimesters to liquefied petroleum gas (LPG) or improved biomass stoves - vs control (traditional three-stone open fire).
Metabolic dysfunction-associated steatotic liver disease and type 2 diabetes: A dual threat to cardiac dysfunction progression.

Metabolic dysfunction-associated steatotic liver disease (MASLD), particularly in patients with type 2 diabetes mellitus (T2DM), is increasingly recognized as a multi-system disease that affects both hepatic and cardiovascular health. This study explores the association between MASLD-related liver fibrosis and cardiac dysfunction, focusing on how liver fibrosis contributes to cardiac remodeling and dysfunction. Cernea 's research highlights the strong correlation between liver fibrosis and changes in left ventricular mass, left atrial dimensions, and systolic and diastolic function in diabetic patients.
