Interpretive Summary: Animal models to study human disease conditions are essential if progress to be made in the treatment of these conditions. One of these disease conditions is atrial fibrillation (AF) in people. AF is the most common sustained heart arrhythmia with significant negative impact on human health and a high death rate. In people, the prevalence of AF increases with age developing slowly over many decades of life. This is the first study to generate a goat model with specific targeted sensitivity to AF. This study will open new avenues for research into the treatment and prevention of AF in people.

Technical Abstract: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in people with significant morbidity and mortality. There is a strong association between atrial fibrosis and AF. Transforming growth factor B1 (TGF-B1) is an essential mediator of atrial fibrosis in animal models and human patients. This is the first study to generate a transgenic goat model with TGF-B1-induced atrial fibrosis leading to increased AF susceptibility. As research progresses, this goat model will provide novel methods to study AF in people and subsequently provide better options for treatment and prevention of this disease.
