Left ventricular diastolic function and respiratory outcomes in preterm infants: a retrospective study.

The role of left ventricular (LV) diastolic pressure in the pathophysiology of bronchopulmonary dysplasia (BPD) is unclear. We evaluated the trajectory of echocardiographic parameters of LV diastolic ... We retrospectively analysed measurements of LV diastolic function (E, e', A, Ee' and E/A ratios) in infants below 32 weeks' gestation (GA). We compared infants with and without BPD by two-way RM ANOVA... We included 72 infants. Ee' ratio at 28 days was significantly associated with the duration of respiratory support (beta (std. error) = 5.32 (1.82), p = 0.005) and BPD (beta = 0.27 (0.10), p = 0.008).... LV diastolic function associated with elevated LV filling pressure may contribute to the pathophysiology of BPD. Serial echocardiographic measurements could identify infants at risk of worse respirato... In very preterm infants, we assessed the trajectory of left ventricular diastolic function by serial echocardiographic evaluations and evaluated its association with respiratory outcomes. On average, ...

A Novel Continuous Left Ventricular Diastolic Function Score Using Machine Learning.

Unlike left ventricular (LV) ejection fraction, which provides a precise, reliable, and prognostically valuable measure of systolic function, there is no single analogous measure of LV diastolic funct... We aimed to develop a continuous score to grade LV diastolic function using machine learning modeling of echocardiographic data.... Consecutive echo studies performed at a tertiary-care center between February 1, 2010, and March 31, 2016, were assessed, excluding studies containing features that would interfere with diastolic func... A total of 28,986 studies were included; 23,188 studies were used to train the models, and 5,798 studies were used for validation. The models were able to reclassify studies with high agreement to the... Machine learning can assimilate echocardiographic data and generate an automated continuous diastolic function score that corresponds well with current diastolic function grading recommendations....

The correlation of pericoronary adipose tissue with coronary artery disease and left ventricular function.

We sought to investigate the correlation of pericoronary adipose tissue with coronary artery disease and left ventricular (LV) function.... Participants with clinically suspected coronary artery disease were enrolled. All participants underwent coronary computed tomography angiography (CCTA) and echocardiography followed by invasive coron... One hundred and fifty-nine participants (mean age, 64.55 ± 10.64 years; men, 65.4% [104/159]) were included in the final analysis. Risk factors for coronary artery disease, such as hypertension, diabe... The FAI was positively correlated with the LV function but was not associated with the severity of coronary artery disease....

Left ventricular function and mechanics in backs and forwards elite rugby union players.

Thirty-nine elite male RU players and twenty sedentary controls have been examined using resting echocardiography. RU players were divided into two groups, forwards (... The elite RU players exhibited an LV remodelling characterized by an increase in LV mass indexed to body surface area (82.2 ± 13.2... RU players exhibited an increase in LV mass which was more pronounced in forwards. In forwards, LV global longitudinal strain was depressed, LV filling pressures were decreased, and LV relaxation depr...

Longitudinal Changes in Left Ventricular Diastolic Function in Late Life: The ARIC Study.

There is limited data regarding longitudinal changes of diastolic function in the very old, who are at the highest risk for heart failure (HF).... This study aims to quantify intraindividual longitudinal changes of diastolic function over 6 years in late life.... The authors studied 2,524 older adult participants in the prospective community-based ARIC (Atherosclerosis Risk In Communities) study who underwent protocol-based echocardiography at study visits 5 (... Mean age was 74 ± 4 years at visit 5 and 80 ± 4 at visit 7, 59% were women, and 24% were Black. At visit 5, mean e'... Diastolic function generally deteriorates over 6.6 years in late life, particularly among persons with CV risk factors, and is associated with development of dyspnea. Further studies are necessary to ...

Maternal left ventricular function and adverse neonatal outcomes in women with cardiac disease.

To evaluate the relationship between maternal left ventricular systolic function, utero-placental circulation, and risk of adverse neonatal outcomes in women with cardiac disease.... 119 women managed in the pregnancy heart clinic (2019-2021) were identified. Women were classified by their primary cardiac condition. Adverse neonatal outcomes were: low birth weight (< 2500 g), smal... Adverse neonatal outcomes occurred in 28 neonates (24%); most frequently in valvular heart disease (n = 8) and cardiomyopathy (n = 7). Small-for-gestational-age neonates were most common in women with... Women with cardiac disease may not tolerate cardiovascular adaptations required during pregnancy to support fetal growth. Adverse neonatal outcomes were associated with reduced left ventricular systol...

Non-invasive myocardial work index contributes to early identification of impaired left ventricular myocardial function in uremic patients with preserved left ventricular ejection fraction.

Cardiac damage is the leading cause of death in uremic patients. This study aimed to evaluate the application of non-invasive myocardial work index (NIMWI) by echocardiography in assessing the left ve... Twenty-six uremic patients and 27 age- and sex-matched healthy volunteers were enrolled in the study. Except for the conventional echocardiographic parameters, the LV myocardial work (MW) parameters i... Compared with the normal group, GWW was significantly increased and GWE decreased in the uremic group (P < 0.05). Area under the curve (AUC) for GWE by the ROC analysis was 0.966. The best threshold, ... NIMWI may be applied to assess the global MW of uremic patients. The presence of reduced GWE can help identify impaired left ventricular myocardial function in uremic patients with preserved LV ejecti...
