Unraveling Cardiac Dynamics: Atrial Fibrillation's Role
Atrial fibrillation (AF) can lead to a decline in ejection fraction (EF), showcasing a gradual remodeling of the heart's function. In certain patients, AF may indicate the presence of underlying cardiomyopathy, serving either as a contributing cause or a decompensating factor for heart failure. Understanding this relationship is vital, particularly since a significant portion of cardiac output relies on the atrial kick; its absence during AF can precipitate heart failure symptoms. The interplay between AF and heart failure illustrates the complex dynamics of cardiac health, particularly in discerning causation versus correlation.
