To develop a predictive model for improvement of ejection fraction 1 year after heart failure with reduced ejection fraction (HFrEF) following acute ST-segment elevation myocardial infarction (STEMI). This nested case-control study included STEMI patients diagnosed with HFrEF from a prospective multicenter multimodality imaging cohort between August 2014 and March 2021. Based on the improvement of left ventricular ejection fraction (LVEF) at baseline and 1-year follow-up, the patients were classified into the heart failure with improved ejection fraction (HFimpEF) group and the persistent HFrEF group.

Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the ideal location of a measurement plane remains unclear. This study aims to systematically examine how varying measurement locations affect RVol quantification and determine the optimal location using the momentum conservation principle of a free jet.

Purpose: This study aims to assess whether water exchange rate (k), a surrogate for blood-brain barrier (BBB) permeability, is associated with functional outcomes in patients with acute ischemic stroke (AIS).
Methods: We studied 22 AIS patients enrolled from 1/2022 to 4/2024 who underwent multi-modal non-contrast imaging on a 3.0-Tesla scanner, including DP-pCASL, DTI, NODDI and MAP imaging.
Volume-viscosity swallow test to facilitate individualized dietary modifications for dysphagia following intracerebral hemorrhage.

Geriatric Care Research Center, Xiamen Medical College, Xiamen, Fujian, 361023, China.
Purpose: This study examined the effects of individualized dietary modifications based on the volume-viscosity swallow test (V-VST) on functional oral intake, incidence of pneumonia, and swallowing-related quality of life in individuals with intracerebral hemorrhage.
Methods: One hundred and seven participants with signs of dysphagia in the acute and early subacute phases of stroke following intracerebral hemorrhage were randomly assigned into an experimental group for individualized dietary modifications based on V-VST plus routine standard care (n = 53), and a control group for routine care alone (n = 54). Incidence of pneumonia, functional oral intake scale (FOIS) ratings and Eating Assessment Tool (EAT-10) scores before and after intervention were evaluated.
Clinical Utility of Systolic Left Ventricular Ejection Fraction in Atrial Fibrillation: Role of Prospective ECG-Triggered Cardiac CT.

Division of Cardiology, University of Ottawa Heart Institute, Canada. Electronic address:
Background: The assessment of left ventricular (LV) systolic function and quantification of LV ejection fraction (EF) in patients with atrial fibrillation (AF) can be difficult. We previously demonstrated that LV volume changes over the 100 ms of systole (LVEF) can be used as a measure of LV systolic function.
Objective: We sought to evaluate the applicability of LVEF in AF patients.
