Arrhythmia News and Research

RSS

An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.

New signaling mechanism implicated in the development of ventricular fibrillation

A study led by Guadalupe Sabio and José Jalife at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) in Madrid has identified a new signaling mechanism implicated in the development of ventricular fibrillation, a type of arrhythmia, or irregular heartbeat.

Image-guided procedure may alleviate parosmia symptoms in long COVID patients

Using an image-guided minimally invasive procedure, researchers may be able to restore the sense of smell in patients who have suffered with long-COVID, according to research being presented next week at the annual meeting of the Radiological Society of North America.

Lasting heart concerns in kids post-MIS-C: Study urges ongoing cardiac checks

Researchers evaluated the long-term cardiovascular effects in children after treatment for MIS-C, a condition linked to COVID-19. They found that regardless of initial heart injury, most children displayed persistent cardiac abnormalities, underscoring the importance of ongoing cardiac monitoring post-recovery.

Intensive blood pressure treatment lowers risk of cardiovascular events in high-risk patients

An intensive three-year intervention to lower the top blood pressure number to less than 120 mm Hg was more effective at preventing death, heart attack, stroke and other cardiovascular events in adults at high risk for cardiovascular disease, compared to the standard treatment target of under 140 mm Hg, according to late-breaking science presented today at the American Heart Association's Scientific Sessions 2023.

CRISPR-based gene-editing therapy could offer hope for people with inherited high LDL cholesterol

A single infusion of a CRISPR-based gene-editing therapy significantly reduced low-density lipoprotein cholesterol (LDL, the "bad cholesterol") in people who carry one gene for the inherited condition that results in very high LDL cholesterol levels and a high risk of heart attack at an early age, according to late-breaking science presented today at the American Heart Association's Scientific Sessions 2023.

Regular marijuana use may raise the risk for heart failure, stroke or heart attack

Using marijuana regularly may raise the risk for heart failure, stroke or heart attack even after accounting for other cardiovascular risk factors such as Type 2 diabetes, high blood pressure and obesity, according to two preliminary studies to be presented at the American Heart Association's Scientific Sessions 2023.

A four-stage classification of heart attack based on heart muscle damage

Heart attacks, or acute myocardial infarction (MI), are one of the leading causes of death worldwide. The newly released Canadian Cardiovascular Society Classification of Acute Myocardial Infarction (CCS-AMI) appearing in the Canadian Journal of Cardiology, published by Elsevier, presents a four-stage classification of heart attack based on heart muscle damage.
