A gene associated with sudden cardiac death has been identified using implantable cardioverter defibrillator (ICD) monitoring. The GNAS gene polymorphism predicted ventricular tachyarrhythmias and sudden cardiac death in patients from the DISCOVERY trial and Oregon-SUDS study.
A new small, wireless self-contained pacemaker has been found safe and effective for patients. The study aims to address the limitations of traditional pacemakers, which pose minimal risk but can lead to short- or long-term complications.
Scientists from the University of Chicago discovered that DNA variants in SCN10A regulate SCN5A expression, suggesting a primary role for SCN5A in cardiac arrhythmia risk. The study highlights the importance of evaluating functional targets of genome-wide association study hits to avoid costly implications.
The European Society of Cardiology and the European Heart Rhythm Association will hold a joint Congress annually from 2014 to 2017, featuring four main topics: electrophysiology, devices, non-invasive EP, and basic science. The agreement aims to improve scientific collaboration and quality among cardiac electrophysiology communities.
A University of Warwick researcher has demonstrated that an Xbox chip can be used as a cheaper alternative for modeling complex processes like cardiac arrhythmias. The study found that the XBox 360 GPU can perform high-end parallel computing on domestic hardware, saving researchers thousands of pounds.
A randomized controlled trial found that fish oil supplementation prevented a reduction in heart rate variability in elderly subjects exposed to indoor air pollutant particles. In contrast, soy oil supplements showed a marginal, nonsignificant protective effect against the negative impact of particulate matter on heart rate variability.
A European multi-centre study found that eating fish oil did little to reduce the risk of heart rhythm problems, cardiac arrest or arrhythmia in patients with an increased risk. The Study on Omega-3 Fatty acids and ventricular Arrhythmia (SOFA) investigated the effect of taking fish oil capsules on life-threatening cardiac arrhythmia i...
An international team has defined a previously undescribed inherited cardiac arrhythmia syndrome caused by mutations in the ankyrin-B gene. The syndrome, distinct from Long QT Syndrome, is characterized by abnormal heartbeats and increased risk of sudden death, particularly among young people.
A study published in Nature reveals a specific gene mutation causing inherited Long QT Syndrome, leading to fatal cardiac arrhythmias and sudden death. Researchers identified the E1425G mutation in ankyrin-B, a protein crucial for heart muscle cell function.
