2. Role of AFib in Heart Failure Development
Moving onto the second fact, the role that AFib plays in the development of heart failure cannot be overstated. The heart’s rhythm is controlled by a natural pacemaker (the sinus node) that produces electrical impulses. In AFib, these electrical signals are chaotic, leading to irregular contractions of the heart’s atria.
The two upper chambers of the heart, the atria, beat chaotically and irregularly when affected by AFib. They function out of coordination with the two lower chambers of the heart, the ventricles. This disharmony results in inefficient pumping of blood, causing it to pool in the atria. The stagnant blood can form clots, which if dislodged, can travel to the brain, causing a stroke.
Moreover, the persistent rapid and irregular heartbeat can overwork the heart muscles, leading to heart failure over time. This overworking of the heart can damage the heart muscles, reducing their efficiency to pump blood.
Understanding this intricate connection between AFib and heart failure is crucial in its effective management. By controlling AFib, the risk of heart failure can be significantly reduced.
On the other hand, if AFib is not managed properly, it can expedite the progression towards heart failure, leading to a deteriorated quality of life and increased mortality. Therefore, aggressive management of AFib can lead to improved heart health and a better prognosis for those at risk. (2)
