There are frequent clinical Cases in Cardiological practice when cardiac failure develops together with normal systolic function of left ventricle. In these patients after revealing the diastolic dysfunction the heart diastolic failure is diagnosed, but in frequent cases this diagnosis is based on exclusion method. According to Framingham data the number of patients with clinically manifested diastolic dysfunction is high; it is age-dependent and reveals in women mostly; that means that the problem is social as well as medical one. Thus the study of pathogenesis, diagnostic and treatment opportunities of heart diastolic insufficiency is of great actuality. The present article reviews the studies related to the problem abovementioned.

The influence of microplastics on hypertension-associated cardiovascular injury via the modulation of gut microbiota.
Environ Pollut

Microplastics (MPs) have been found to interfere with the gut microbiota and compromise the integrity of the gut barrier. Excessive exposure to MPs markedly elevates the risk of cardiovascular disease, yet their influence on hypertension remains elusive, calling for investigation into their potential impacts on blood pressure (BP) regulation. In the present study, an increase in the concentration of MPs was observed in the fecal samples of individuals suffering from hypertension, as compared to the controls.

Department of Endocrinology, Sher-i-Kashmir Institute of Medical Sciences (SKIMS), Srinagar, J&K, India.
Background: Primary hyperparathyroidism (PHPT) is associated with hypertension, left ventricular hypertrophy, and myocardial and valvular calcifications, leading to increased mortality rates. While the association between PHPT and diastolic dysfunction has been well-documented, data on systolic dysfunction and its reversal after curative parathyroidectomy (PTX) remains limited.
Purpose: To evaluate the effect of PTX on cardiovascular parameters, especially systolic dysfunction, in PHPT patients using conventional and speckle-tracking echocardiography (STE).
Left Atrial Markers in Diagnosing and Prognosticating Non-Ischemic Cardiomyopathies: Ready for Prime Time?
Echocardiography
February 2025
Department of Cardiology, Loyola University Medical Center, Maywood, Illinois, USA.
The left atrium (LA) is pivotal in cardiac hemodynamics, serving as a dynamic indicator of left ventricular (LV) compliance and diastolic function. The LA undergoes structural and functional adaptations in response to hemodynamic stress, infiltrative processes, myocardial injury, and arrhythmic triggers. Remodeling of the LA in response to these stressors directly impacts pulmonary circulation, eventually leading to pulmonary capillary involvement, pulmonary artery hypertension, and eventually right ventricular failure.

Background: Changes in cardiac function and structure as well as their association with the cardiac autonomic nervous system remain incompletely characterized in children with stage 5 chronic kidney disease (CKD) receiving hemodialysis (HD).
Methods: A prospective observational cohort study was conducted on 40 Egyptian children with CKD on regular HD compared to 40 age- and sex-matched healthy children. All participants underwent thorough clinical examination, laboratory investigations, 24-h Holter monitoring, and 2D/4D echocardiographic study (conventional and advanced modalities).

Swine are increasingly utilized in cardiovascular research due to their anatomical and physiological similarities to humans, particularly for studying diastolic dysfunction. While MRI offers excellent structural imaging, echocardiography provides superior real-time assessment of diastolic parameters. To address the lack of standardized methods and reduce variability across studies, we present a comprehensive guide for performing echocardiography in Yorkshire pigs, detailing anatomical considerations, equipment requirements, and technical approaches.
