Dynamic trajectories of left ventricular ejection fraction in heart failure with improved ejection fraction

open access: yesBMC Cardiovascular Disorders
Background Heart failure with improved ejection fraction (HFimpEF) has been regarded as a new heart failure (HF) type in 2022. However, studies on the impact of left ventricular ejection fraction (LVEF) trajectories on the prognosis of patients with ...

Quasi‐Static to Supersonic Energy Absorption of Nanoarchitected Tubulanes and Schwarzites

open access: yesAdvanced Functional Materials, EarlyView.
Nanoarchitected energy‐absorptive Tubulanes exhibit record energy absorption under quasi‐static conditions and exceptional inelastic energy dissipation under 750 m s−1 ballistics impact, with high performance spanning strain rates of 12 orders of magnitude.

Prevalence of prediabetes and undiagnosed diabetes in patients with HFpEF and HFrEF and associated clinical outcomes [PDF]

open access: yes, 2017
Purpose: The prevalence and consequences of prediabetic dysglycemia and undiagnosed diabetes is unknown in patients with heart failure (HF) and preserved ejection fraction (HFpEF) and has not been compared to heart failure and reduced ejection ...

High‐Resolution and Real‐Time In Situ Generation of Cellular Spheroids by Laser‐Assisted Bioprinting for Guided Microvascularization

open access: yesAdvanced Functional Materials, EarlyView.
Micro‐injection laser‐assisted bioprinting enables ultrafast and precise patterning of small endothelial cell spheroids by injecting a highly concentrated single‐cell suspension into GelMA/ColMA hydrogels. In co‐culture with fibroblasts, controlled pre‐vasculogenic network formation is obtained at microscale resolution.

Impact of Coronary Artery Bypass Graft on left Ventricular Systolic Function

open access: yesAdvanced Medical Journal
Background& objective: Coronary artery disease is the common cause of disease-specific mortality and morbidity in Iraq. The objective was to evaluate the effect of coronary artery bypass graft surgery on left ventricular systolic function.

Management, survival, and predictors of mortality among hospitalized heart failure patients at Debre Markos comprehensive specialized hospital, Northwest Ethiopia: Prospective cohort study

open access: yesSAGE Open Medicine, 2021
Introduction: Heart failure is a major public health problem worldwide. Since heart failure with reduced ejection fraction and preserved ejection fraction are different clinical entities, in-hospital mortality may occur at different rates.

Left ventricular function at 24 hours, 14 days and 6 months after acute myocardial infarction [PDF]

open access: yes, 2017
To determine the natural history of left ventricular function at rest and during exercise and to assess the impact of this variable on subsequent mortality, 165 patients were studied with radionuclide angiography within 24 hours of acute myocardial ...

Understanding the Role of Superhydrophobicity and Superhydrophilicity in Salt‐Spray Corrosion of Nanosecond Pulsed Laser‐Textured AA2024 Alloy

open access: yesAdvanced Functional Materials, EarlyView.
Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

Preoperative ejection fraction as a predictor of survival after coronary artery bypass grafting: comparison with a matched general population

open access: yesJournal of Cardiothoracic Surgery, 2010
Background Preoperative left ventricular dysfunction is an established risk factor for early and late mortality after revascularization. This retrospective analysis demonstrates the effects of preoperative ejection fraction on the short-term and long ...
