Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

Advanced Science, EarlyView.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

Racing hearts in the ED: When atrial tachyarrhythmias Herald hidden culprits

JEM Reports
Background: Atrial Fibrillation (AF) is the most common sustained arrhythmia in the general population. Patients with atrial fibrillations commonly go to Emergency Departments (ED) with complications or aggravation of symptoms.

Management of sudden cardiac death in cardiac sarcoidosis using the wearable cardioverter defibrillator. [PDF]

PLoS ONE, 2018
Patients with cardiac sarcoidosis are at increased risk of ventricular tachycardia/fibrillation.We tested the hypothesis that the wearable cardioverter defibrillator can be used to mitigate the risk of sudden cardiac death among cardiac sarcoidosis ...

Pulseless Electrical Activity as the Initial Cardiac Arrest Rhythm: Importance of Preexisting Left Ventricular Function

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Pulseless electrical activity (PEA) is a common initial rhythm in cardiac arrest. A substantial number of PEA arrests are caused by coronary ischemia in the setting of acute coronary occlusion, but the underlying mechanism is not well ...

Novel SCN5A mutation associated with idiopathic ventricular fibrillation due to subclinical Brugada syndrome

Cardiogenetics, 2011
Idiopathic ventricular fibrillation can be caused by subclinical channelopathies such as Brugada syndrome. Our objective is to study the clinical behaviour of a new SCN5A mutation found in a woman with idiopathic ventricular fibrillation.

Ventricular fibrillation during carotid endarterectomy and bailout stenting: a case report

JA Clinical Reports, 2022
Background Carotid artery manipulation is not a special technique but reports of intraoperative ventricular fibrillation are rare. The risk of fatal arrhythmias may be hidden behind routine surgical techniques and anesthetic management.

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.
