The presence of a left atrial thrombus is closely associated with atrial fibrillation. Atrial fibrillation is a type of irregular heartbeat that can lead to blood pooling in the left atrium, which creates a higher risk for clot formation. When the atria do not contract effectively, blood may not flow smoothly, leading to stagnant blood that can eventually form clots.

In patients with atrial fibrillation, the risk of developing a left atrial thrombus, particularly in the left atrial appendage, significantly increases, making it a critical concern in the management of heart rhythm abnormalities. Effective identification and management of this condition are essential to prevent complications such as stroke, which can arise from embolization of the thrombus.

While other factors such as hyperlipidemia, pulmonary embolism, and mitral valve stenosis may have connections to heart health issues, they do not directly indicate the presence of a left atrial thrombus in the way that atrial fibrillation does.
