Abstract
The patients with advanced interatrial block (A-IAB) (P≥120ms plus±pattern in II, III and aVF) present more frequently atrial fibrillation (Bayes syndrome) and even stroke and dementia. The following considerations have to be considered: AF is not the final cause of stroke; atrial fibrotic CM is the substrate of both AF and A-IAB; there are many similarities between these two processes. Very often A-IAB is a precursor of AF and both may be considered mediators of stroke; there is a clear evidence that A-IAB and AF are risk factors of stroke, and even dementia, and global, CV, and sudden death; in a group of patients in SR (A-IAB) that are risk factors of AF and stroke, we have to perform a randomized to demonstrate the benefits to anti-coagulate patients in SN without documented AF; if this trial is positive, we have to establish a score of risk of stroke for patients in sinus rhythm to be used at a global level; until then, we can take decisions at individual level according to the careful observations of ECG (P-wave) and other
parameters (CHA2DS2-V, ambiental arrhythmias, detection of fibrosis, etc.).
