Investigating how Endothelin-1 affects atrial fibrillation development and progression

Official title: Role of Endothelin-1 signaling in the development and progression of atrial fibrillation

Funded at Northwestern University at Chicago · NIH-10914162 · Data updated 2026-11-12

This study is looking at how a molecule called Endothelin-1 affects heart rhythm problems like atrial fibrillation, with the goal of finding new ways to help people who have this condition feel better.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals at risk for atrial fibrillation, particularly older adults or those with conditions like heart failure, hypertension, or diabetes.

Less likely to help

Patients who do not have atrial fibrillation or related cardiovascular conditions may not benefit from this research.

What this research studies

This research focuses on understanding the role of Endothelin-1, a molecule involved in blood vessel function, in the development and worsening of atrial fibrillation (AF), a common heart rhythm disorder. Using large animal models, the study aims to explore how endothelial dysfunction contributes to AF and its transition from a temporary to a more persistent form. By examining the timing and location of these changes, researchers hope to uncover new therapeutic targets that could lead to more effective treatments for patients suffering from AF.

Why it matters

Potential benefit: If successful, this research could lead to improved therapies for atrial fibrillation, potentially reducing the risk of stroke and other complications for patients.

How similar studies have gone: Previous studies have indicated a link between endothelial dysfunction and atrial fibrillation, but this research aims to establish a causal relationship, making it a novel approach.
