Non‐Invasive Diagnosis of Hypertrophic Cardiomyopathy by Breath

Advanced Sensor Research, EarlyView.
The use of sensor technologies for the diagnosis of hypertrophic cardiomyopathy (HCM) by identification of volatile organic compounds (VOCs) in breath samples. By combining gas chromatography‐mass spectrometry (GC‐MS) and electronic nose (eNose) platforms, specific VOC patterns associated with HCM are detected and analyzed.

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 ...

Electrophysiological Mechanisms of Ventricular Fibrillation Induction [PDF]

, 2005
Ventricular fibrillation (VF) is known as a main responsible cause of sudden cardiac death which claims thousands of lives each year. Although the mechanism of VF induction has been investigated for over a century, its definite mechanism is still ...

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

A Novel Protein NAB1‐356 Encoded by circRNA circNAB1 Mitigates Atrial Fibrillation by Reducing Inflammation and Fibrosis

Advanced Science, EarlyView.
The circRNA circNAB1 is downregulated in AF patient. Silencing circNAB1 promotes collagen deposition and inflammation, whereas overexpression reduces AF susceptibility. circNAB1 encodes the protein NAB1 356 that interacts with EGR1 to mitigate fibrosis and inflammation.

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, Volume 12, Issue 17, May 8, 2025.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Nifekalant

JACC: Case Reports, 2020
Atrial fibrillation along with accessory pathway–induced ventricular pre-excitation may be life-threatening due to the high risk of developing severe hypotension, ventricular fibrillation, and sudden death. We demonstrate nifekalant as an effective agent

Discordant Alternans as a Mechanism for Initiation of Ventricular Fibrillation In Vitro

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Ventricular tachyarrhythmias are often preceded by short sequences of premature ventricular complexes. In a previous study, a restitution‐based computational model predicted which sequences of stimulated premature complexes were most likely to
