  Figure 1. Left Atrial Myopathy and Cryptogenic Stroke Cryptogenic stroke is a heterogeneous disease with multiple clinical risk factors. Growing evidence suggests left atrial electrical and mechanical dysfunction (ie, LA myopathy) are associated with cryptogenic stroke. Whether LA myopathy, independent of atrial fibrillation, is causally related to cryptogenic stroke remains unclear. LA = left atrial.
