Is baseline P-wave morphology associated with the risk of incident ischemic stroke independent of atrial fibrillation?
Baseline P-wave morphology is associated with incident stroke independent of atrial fibrillation, suggesting atrial cardiopathy as a potential mechanism.
We found an association between baseline P-wave morphology and incident stroke even after accounting for AF. This association may reflect an atrial cardiopathy that leads to stroke in the absence of AF.
Kamel et al. (2014) studied this question.
