“…There is currently not a large body of literature of the ability of the P-wave axis to predict AF independent of stroke, and it was therefore not included in this score. Advanced IAB has been shown to be predictive of stroke in several populations (Lindow & Baranchuk, 2018;O'Neal, Kamel, et al, 2016). However, as only twelve patients experienced a stroke during the follow-up period in our study, we did not evaluate the ability of MVP ECG score to predict stroke.…”

“…La relativamente baja incidencia de ACV vista en pacientes centenarios con FA probablemente se debió al hecho de que estos se beneficiaron del tratamiento con anticoagulación que estaban recibiendo para dicha arritmia, mientras que este no era el caso para aquellos con BIA-A 24 . Lindow y Baranchuk 25 publicaron el particular caso de una paciente de 79 años que, durante unas vacaciones en el exterior, sufrió una hemiplejia del lado derecho. Se la admitió en el hospital más cercano y se inició trombólisis.…”

El síndrome de Bayés es una entidad clínica que se define como la asociación entre la presencia de bloqueo interauricular avanzado (BIA-A), y el desarrollo de taquiarritmias supraventriculares (TSV), siendo la fibrilación auricular (FA), la más frecuente. Esta asociación salió a la luz con los estudios del Prof. Antoni Bayés de Luna en los años ‘80. Estudios realizados posteriormente por otros grupos encontraron una fuerte asociación entre este síndrome y la ocurrencia de fenómenos tromboembólicos, siendo el accidente cerebrovascular (ACV) el más grave. Del mismo modo, se documentó una asociación con deterioro cognitivo y demencia. Esto generó la pregunta acerca de si la terapia de anticoagulación previa a la documentación de FA podría prevenir la ocurrencia de tromboembolismos asociados al BIA-A y de esta manera preservar el estado cognitivo. Esta pregunta permanece, aún hoy, sin respuesta definitiva. Existen estudios en diferentes estadios de su desarrollo cuyo objetivo es comparar la efectividad de la anticoagulación en pacientes con BIA-A y sin FA documentada. Los resultados de los mismos permitirán establecer la efectividad de esta opción terapéutica temprana y, de manera conclusiva, definir si, para decidir anticoagular un paciente, la FA tiene que ser previamente documentada o no.

“…Thromboembolism of cardiac source is a common cause of stroke, yet embolic events of an undetermined source may account for 25% of all cerebral infarcts. In this scenario, despite prolonged ECG monitoring techniques are often employed, detection of AF is only seen in a modest 20% to 40% of stroke patients after 3 years of continued monitoring 1–4 . The NAVIGATE ESUS and RE‐SPECT ESUS trials showed that empiric anticoagulation is not routinely indicated in patients with cryptogenic stroke without documentation of AF 5,6 .…”

Background Empiric anticoagulation is not routinely indicated in patients with cryptogenic stroke without documentation of atrial fibrillation (AF). Therefore, identification of patients at increased risk of AF from this vulnerable group is vital. Objectives To identify electrocardiographic (ECG) predictors of AF in patients with cryptogenic stroke or transient ischemic attack (TIA) undergoing insertion of an implantable cardiac monitor (ICM). Methods In this single‐center study, 48 patients with cryptogenic stroke or TIA had an ICM implanted for detection of AF between January 2013 and September 2019. Patients with and without AF were compared in terms of p‐wave duration and a novel index (MVP score). Results During a mean follow‐up of 16 ± 14 months, AF was detected in seven patients (15%). Diagnosis of AF was made after a mean of 10 ± 14 months, with time to first AF detection ranging between 1 and 40 months. Patients with AF had a longer p‐wave duration (136 ± 9 ms vs. 116 ± 10 ms; p = .0001) and a higher MVP score (4.5 ± 1.2 vs. 2.0 ± 0.9, p = .0001) than those without AF. Advanced interatrial block (IAB) was observed in 43% of patients with ICM evidence of AF and 0% of those without AF (p = .002). Age, LA size or LVEF were not predictors of AF. Conclusion An increased p‐wave duration, advanced IAB and high MVP score are associated with AF occurrence in patients with cryptogenic stroke. Identifying patients with these markers may be helpful as they may benefit from more exhaustive and prolonged monitoring.
