dc.description.abstractBackground and objectives Atrial fibrillation is a known risk factor for cryptogenic stroke and therefore requires early detection and prompt management. We investigated predictors of stroke recurrence in patients with cryptogenic stroke and concomitant non-sustained atrial tachycardia but not atrial fibrillation. Subjects and methods We investigated 390 patients (219 men, mean age 67 ± 12 years) diagnosed with stroke and non-sustained atrial tachycardia on 24-h Holter monitoring and recorded the total number of atrial premature contractions identified by the Holter monitor. Multiple atrial premature contractions were defined as atrial premature contractions > 34 beats/day. We analyzed the rates of 5-year freedom from stroke recurrence or atrial fibrillation and investigated independent predictors of stroke recurrence and undiagnosed atrial fibrillation. Results The mean follow-up period was 35 ± 21 months, and the overall stroke recurrence rate was 9.0%. Kaplan–Meier survival analysis revealed that the rate of freedom from stroke recurrence was significantly lower in patients with multiple atrial premature contractions. Also, the patients with multiple atrial premature contractions had higher cumulative incidence rate of new-onset AF (p = 0.019). Multivariate analysis showed that multiple atrial premature contractions (hazard ratio 2.49, 95% confidence interval 1.05–5.88, p = 0.038), cigarette smoking status (hazard ratio 2.66, 95% confidence interval 1.15–6.17, p = 0.022), and the left atrial volume index (hazard ratio 1.05, 95% confidence interval 1.01–1.09, p = 0.020) were significantly associated with stroke recurrence in patients with cryptogenic stroke. However, these factors were not statistically significant predictors of future onset of atrial fibrillation. Conclusions Multiple atrial premature contractions were significantly correlated with an increased left atrial volume index, which could predict future onset of atrial fibrillation and stroke recurrence. This study showed that multiple atrial premature contractions predict stroke recurrence in patients with cryptogenic stroke without atrial fibrillation.-
