The value of left atrial strain and strain rate in predicting left atrial appendage stasis in patients with nonvalvular atrial fibrillation

Cardiology Journal, 2018
This study aimed to investigate the value of left atrial (LA) strain and strain rate (S/SR) by transthoracic echocardiography (TTE) in predicting left atrial appendage (LAA) stasis, in order to find a way for LAA stasis screening which is easily performed in patients with nonvalvular atrial fibrillation (NVAF).One hundred and thirty NVAF patients ...

Obesity and left atrial function: state of the art

Global Cardiology
Obesity is an established risk factor for heart failure (HF), with every unit increase in body mass index, the risk of HF increases by 5-7%. Obesity can especially increase the risk for HF with preserved ejection fraction due to left atrial (LA ...

Atrial cellular electrophysiological changes in patients with ventricular dysfunction may predispose to AF [PDF]

, 2009
<b>Background:</b> Left ventricular systolic dysfunction (LVSD) is a risk factor for atrial fibrillation (AF), but the atrial cellular electrophysiological mechanisms in humans are unclear.

Clinical utility of the left atrial strain analysis. [PDF]

J Echocardiogr
Abstract The importance of left atrial (LA) function is recognized, especially when left ventricular function fails or atrial fibrillation occurs and heart failure (HF) develops. A compensatory mechanism of LA function unremittingly operates to maintain cardiac performance and prevent the occurrence of HF.

The Clinical Applications of Left Atrial Strain: A Comprehensive Review

Medicina
Left atrial (LA) strain imaging, which measures the deformation of the LA using speckle-tracing echocardiography (STE), has emerged recently as an exciting tool to help provide diagnostic and prognostic information for patients with a broad range of ...

Protease‐Activated Theranostic Nanomedicine for Endometriosis Treatment

Advanced Functional Materials, EarlyView.
Endometriosis is a chronic gynecological disorder that affects a substantial proportion of reproductive‐aged women. In this study, we identify aberrant overexpression of matrix metalloproteinase‐9 (MMP‐9) in endometriotic lesions and develop a novel multifunctional nanomedicine that integrates MMP‐9‐targeted therapy, ratiometric photoacoustic (PA ...

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

Advanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced
