Abstract
<p><strong>Background: </strong>Cardioembolic stroke due to atrial fibrillation (AF) is responsible for up to 33% of all ischemic strokes. The identification of paroxysmal atrial fibrillation (PAF) may have crucial prognostic impact. 24-hour Holter monitoring has been increasingly used in stroke and transient ischemic attack (TIA) patients as a routine investigation to search for occult PAF. The purpose of this study was to observe the incidence AF at a long-term follow-up and to evaluate the clinical and imagological predictors of new onset AF.</p> <p><strong>Methods: </strong>We selected patients in sinus rhythm who performed Holter between October 2009 and October 2011 in the setting of post stroke or TIA. These patients were followed for 8 to 10 years. Clinical and echocardiographic data were collected. Patients with AF were compared to those without AF.</p> <p><strong>Results: </strong>104 patients were included, 54% were males, with a mean age of 63.8±14.7 years at the time of the event. Concerning to cardiovascular risk factors, 59% had hypertension, 47% had dyslipidemia, 14% had diabetes, 44% were smokers or previous smokers and 67% were high consumers of alcohol. 79.8% of patients had a stroke (41.1% PACI) and 21.2% a TIA. PAF was detected in 1.9% of patients, all with previous stroke and older than 55. Patients with PAF were compared to the sinus rhythm ones and no statistically significant differences were found, either concerning to clinical or to imaging data (including left atrium size). At a follow-up of 8 to 10 years, AF was detected in more 11.5% of the patients. There is no association between the presence of cardiovascular risk factors and the development of AF, however patients presented with left atrium enlargement showed a higher incidence of AF at follow-up (14.7% vs 7.9%), but this difference wasn’t statistically significant. Patient’s age and the presence of mitral regurgitation were not related with new onset of AF during follow-up. Patients who developed AF during follow-up had similar mortality as those in sustained sinus rhythm (21.2% vs 16.7%, p=0.724).</p> <p><strong>Conclusions: </strong>Atrial fibrillation is considered the main cause of stroke. In patients post stroke or TIA in sinus rhythm, left atrial enlargement (in contrast to mitral regurgitation and age) is a good predictor of development of AF. Diagnostic of new AF during long-term follow up was not correlated with higher mortality.</p>
