Ischemic Postconditioning Protects Aged Myocardium Against Ischemia/Reperfusion Injury by Regulating Mitochondrial Dynamics via piR‐4913

Advanced Science, EarlyView.
A tiny RNA tips the scales of cardiac injury in aging. piR‐4913 recruits OGT to Drp1 and drives its O‐GlcNAcylation at Thr604, promoting excessive mitochondrial fission that aggravates ischemia‐reperfusion injury. Ischemic postconditioning silences this pathway to restore mitochondrial balance and protect the aged myocardium, revealing piR‐4913 as a ...

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning

Advanced Science, EarlyView.
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...

Left ventricular diastolic dysfunction: identifying presence by left atrial function

Echo Research and Practice, 2018
Objective: The left atrium (LA) is exposed to left ventricular pressure during diastole. Applying the 2016 American Society of Echocardiography left ventricular diastolic function (LVDF) guidelines, this study aims to investigate whether left atrial ...

Left Atrial Pressure Estimation Using Contemporary Guideline Algorithms in Patients with Atrial Fibrillation and Prognosis following Myocardial Infarction

Assessment of diastolic function and left atrial pressures (LAPs) with echocardiography in patients with atrial fibrillation (AF) is challenging and has classically been regarded as a contraindication.1 Nonetheless, estimation of LAP may be clinically ...

Left Atrial Myxoma Mimicking Mitral Stenosis

, 2012
Cardiac myxoma is a benign (non-malignant) neoplasm that represents the most common primary tumour of the heart. We present the case of a 36 year old woman with background hypertension who presented with features of left ventricular failure and seizures,

SFMFNet: Spatial‐Frequency Multiscale Fusion Network for Left Ventricle Segmentation in Echocardiography

Advanced Intelligent Systems, EarlyView.
Automatic left ventricular segmentation in echocardiography is critical for cardiac function assessment but remains challenging due to limited crossdomain feature interaction. This paper proposes SFMFNet, a Spatial‐Frequency Multi‐Scale Fusion Network that integrates multiscale convolution, wavelet transform, and Fourier transform.
