Spiral wave teleportation theory offers new path to defibrillate hearts, terminate arrhythmias

Researchers from Georgia Institute of Technology develop a new method to terminate arrhythmias by disrupting spiral waves with a single designed stimulus, utilizing a concept called 'teleportation' to move the waves out of control. This approach may reduce energy and pain compared to traditional defibrillation.

Action needed to reduce e-cigarette use among adolescents to lower lifetime CVD risk

The American Heart Association warns that e-cigarette use in adolescents can lead to stunted lung development and altered cardiovascular systems, increasing the risk of heart disease over time. Long-term exposure to e-cigarette aerosols has been linked to increased blood pressure, impaired blood vessel function, and arterial stiffness.

New study from Indiana University shows patients with chronic kidney disease who have heart attacks should be offered invasive therapy, countering dominant practices

Researchers found that invasive therapy for non-ST segment elevation myocardial infarction in patients with CKD is associated with lower mortality and reduced risk of cardiac events. The study challenges the dominant practice of offering medical management instead of invasive therapy for this population.

THE LANCET HEALTHY LONGEVITY: Little evidence testosterone treatment increases the risk of cardiovascular events, most in-depth analysis suggests

A comprehensive analysis of testosterone replacement therapy found no increased risk of heart attack, stroke, and other cardiovascular events in the short-to-medium term. Testosterone treatment was also found to reduce serum cholesterol levels, but no significant differences were observed in blood pressure or glycaemic parameters.

New research reveals how the heart repairs after a heart attack

Researchers at Ann & Robert H. Lurie Children's Hospital of Chicago discovered that macrophages play a crucial role in cardiac repair after a heart attack by inducing vascular endothelial growth factor C (VEGFC) and promoting healing. This finding offers new hope for developing novel therapeutic approaches to preserve heart function.

How eating eggs can boost heart health

A recent study published in eLife found that eating up to one egg per day may help lower the risk of cardiovascular disease. The researchers identified 24 metabolites associated with self-reported levels of egg consumption and found that individuals who ate eggs regularly had higher levels of a protein called apolipoprotein A1.
