The aim of the study was to investigate the significance of Doppler echocardiography (echoCG) for assessment of "dry weight" in hemodialysis patients. 43 dialysis patients (20 men and 23 women aged 49 +/- 11 years), receiving 4-hour bicarbonate hemodialysis (HD) 3 times a week, were studied prior to and after HD procedures. M-mode echoCG was performed and left ventricular mass index (LVMI) and ejection fraction (EF) were calculated. Transmitral flow was assessed by Doppler echoCG. Peak velocity of early (E) and late (A) filling, E/A ratio, isovolumic relaxation time (IVRT) and early deceleration time (DT) were detected. Left ventricular hypertrophy (LVH) was detected in 37 (86.0%) patients. EF was lower than 45% in 4 patients. There was significant positive correlation between the amount of ultrafiltration (evaluated in per cents of body mass after HD) and deltaE (r = 0.59; p = 0.001), and there was found no correlation between the amount of ultrafiltration and deltaA. Patients with intradialytic hypotension had substantially higher DT than patients without one (238.7 +/- 64.3 vs. 168.6 +/- 51.2 mc, respectively, p < 0.001). "Dry weight" is associated with increase of early DT over the level normal for the age in hemodialysis patients with left ventricular hypertrophy. Patients with increased early DT are exposed to the high risk of intradialytic hypotension development.

Anthracyclines are the cornerstone of treatment for many malignancies. However, anthracycline cardiotoxicity is a considerable concern given that it can compromise the clinical effectiveness of the treatment and patient survival despite early discontinuation of therapy or dose reduction. Patients with cancer receiving anthracycline treatment can have a reduction in their quality of life and likelihood of survival due to cardiotoxicity, irrespective of their oncological prognosis.

Non-bacterial thrombotic endocarditis (NBTE) is characterised by sterile vegetations on heart valves and often emerges in hypercoagulable states like malignancy. It is frequently underdiagnosed and only comes to light during postmortem examination. Early diagnosis and treatment with anticoagulation can help lower mortality.

: The utilization of intra-aortic balloon pump (IABP) and Impella has been suggested as means of left ventricular unloading in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) patients. This study aimed to assess the local hemodynamic alterations in VA-ECMO patients through simulation analyses. : In this study, a 0D-3D multiscale model was developed, wherein resistance conditions were employed to define the flow-pressure relationship.

Objectives: This fourth report aimed to provide insights into patient characteristics, outcomes, and standardized outcome ratios of patients implanted with durable Mechanical Circulatory Support across participating centers in the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) registry.
Methods: All registered patients receiving durable mechanical circulatory support up to August 2024 were included. Expected number of events were predicted using penalized logistic regression.

Aims: How the underlying etiology and pathophysiology of left ventricular (LV) hypertrophy affects LA remodeling and function remains unexplored. The present study aims to investigate the influence of various hypertrophic phenotypes on LA remodeling and function.
Methods And Results: Patients with LV hypertrophy who underwent cardiac magnetic resonance (CMR) were compared to a control group.
