In this week’s Chaos, researchers used an electrophysiological computer model of the heart’s electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They discovered far less energy is needed than is currently used in state-of-the-art defibrillation techniques. The authors applied an adjoint optimization method and discovered adjusting the duration and the smooth variation in time of the voltage supplied by defibrillation devices is a more efficient mechanism that reduces the energy needed to stop fibrillation by three orders of magnitude.
On a Thursday morning in Dallas, Fiona Strasserking, M.D., chats with her UT Southwestern colleague while internal medicine residents from the University of Zambia log on to their Zoom call. Rafic Berbarie, M.D., Associate Professor in UTSW’s Division of Cardiology, is today’s guest lecturer and the topic is “Evaluation of Chest Pain.”
Researchers at UT Southwestern Medical Center have developed a machine learning model that can identify patients with diabetic cardiomyopathy, a heart condition characterized by abnormal changes in the heart’s structure and function that predisposes them to increased risk of heart failure. The findings, published in the European Journal of Heart Failure, offer a data-driven method to detect a high-risk diabetic cardiomyopathy phenotype, enabling early interventions that could help prevent heart failure in this vulnerable population.
Studies suggest that compared with the general population, people with chronic epilepsy have three times the risk of sudden cardiac death. Researchers have introduced the concept of the “epileptic heart” as “a heart and coronary vasculature damaged by chronic epilepsy… leading to electrical and mechanical dysfunction.”
New Cleveland Clinic research shows that consuming foods with erythritol, a popular artificial sweetener, increases risk of cardiovascular events such as heart attack and stroke. The findings, from a new intervention study in healthy volunteers, show erythritol made platelets (a type of blood cell) more active, which can raise the risk of blood clots.
Scientists at Sanford Burnham Prebys and Salk Institute for Biological Studies have uncovered a new role for a protein known for its role in the brain helping control feelings of hunger or satiety, as well as in the liver to aid the body in maintaining a balance of energy during fasting. The new study shows that this protein also supports the maintenance of heart structure and function, but when it is overactive it causes thickening of the heart muscle, which is associated with heart disease.
An analysis of blood samples from thousands of study participants, led by researchers at UT Southwestern Medical Center, revealed 18 proteins associated with both heart failure and frailty, conditions that commonly develop in late life.
UT Southwestern Medical Center is the No. 1 hospital in Dallas-Fort Worth for the eighth consecutive year and ranks among the nation’s top hospitals for care in 11 specialties – the most of any hospital in Texas, according to U.S. News & World Report’s annual Best Hospitals list released today.
Eating patterns that align with the Mediterranean diet or the dietary approaches to stop hypertension (DASH) diet could help lower cardiovascular disease risk in adults with type 1 diabetes, according to results from a six-year study.
Alcohol researchers have long known that excessive drinking can cause damage to the liver, pancreas, heart, muscle, bone, and brain. However, only a subset of patients with alcohol use disorder (AUD) appear to develop organ damage. New research shows that alcohol-induced gut inflammation is the missing link between unhealthy drinking and organ damage among certain AUD patients.
A team of international researchers has revealed a new, simple clinical test to detect Calcium Release Deficiency Syndrome (CRDS), a life-threatening genetic arrhythmia that causes dangerously fast heartbeats and can lead to severe complications such as sudden cardiac arrest and death.
