New research from a multi-institutional team, published in Nature Cardiovascular Research, reveals that heart failure and atrial fibrillation share underlying genetic and molecular mechanisms, ...
Atrial dysfunction, widely considered a marker or consequence of other heart diseases, is a relevant clinical entity, which is why it is justified to define atrial failure or insufficiency as "a new ...
BIRMINGHAM, Ala. – Millions of adults have atrial fibrillation — an irregular beating of the upper chambers of the heart that yields increased risk of heart failure, stroke and death. Many genetic ...
