A recent study published in JAMA Cardiology found that patients treated with hydroxychloroquine for COVID-19 were at increased risk of electrical changes to the heart and cardiac arrhythmias. The combination of hydroxychloroquine with azithromycin was linked to even greater changes compared to hydroxychloroquine alone.
Researchers at Baylor College of Medicine have successfully used genome editing to correct a genetic mutation causing a rare and deadly heart condition. The study uses CRISPR/Cas9 technology to selectively disrupt the disease-causing gene, reducing arrhythmia symptoms in mice. This breakthrough could lead to a permanent treatment for p...
Researchers found a link between mitral valve prolapse and sudden cardiac death, with 14 cases per 1000 per year associated with the condition. The study identified features such as scarring of the heart muscle and heavy mitral valve leakage that put patients at high risk for serious cardiac arrhythmias.
The EHRA White Book provides comprehensive data on cardiac arrhythmia treatment, including device implantations and interventional procedures. The 2017 edition shows significant disparities in treatment across countries, with higher volumes of device implantations in Western and Northern countries.
Researchers at Kaunas University of Technology are developing multifunctional scales to monitor health and detect potentially life-threatening conditions. The scales can measure arterial stiffness and even recognize the development of hyperkalemia, a condition that requires dialysis.
Researchers discovered a genetic link between Long QT Syndrome (LQTS) and an increased risk for seizures. LQTS patients who experienced seizures were three times more likely to have experienced seizures in the past, and had worse cardiac symptoms.
Scientists have discovered a method to predict certain types of cardiac arrhythmias, allowing for potential prevention and improved heart health. The researchers used mathematical modeling to analyze the transition from normal to abnormal heartbeat patterns in embryonic chicken cells.
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.
