• Atrial high-rate episode duration thresholds and thromboembolic risk: A systematic review and meta-analysis 

      Sagris D., Georgiopoulos G., Pateras K., Perlepe K., Korompoki E., Milionis H., Tsiachris D., Chan C., Lip G.Y.H., Ntaios G. (2021)
      BACKGROUND: Available evidence supports an association between atrial high-rate episode (AHRE) burden and thromboembolic risk, but the necessary extent and duration of AHREs to increase the thromboembolic risk remain to ...
    • Data-driven machine-learning analysis of potential embolic sources in embolic stroke of undetermined source 

      Ntaios G., Weng S.F., Perlepe K., Akyea R., Condon L., Lambrou D., Sirimarco G., Strambo D., Eskandari A., Karagkiozi E., Vemmou A., Korompoki E., Manios E., Makaritsis K., Vemmos K., Michel P. (2021)
      Background and purpose: Hierarchical clustering, a common ‘unsupervised’ machine-learning algorithm, is advantageous for exploring potential underlying aetiology in particularly heterogeneous diseases. We investigated ...
    • Embolic Stroke of Undetermined Source: JACC Review Topic of the Week 

      Ntaios G. (2020)
      The term embolic stroke of undetermined source (ESUS) was introduced in 2014 to describe patients with a nonlacunar ischemic stroke and no convincing etiology. The terms ESUS and cryptogenic stroke are not synonyms, as the ...
    • Prevalence and Overlap of Potential Embolic Sources in Patients With Embolic Stroke of Undetermined Source 

      Ntaios G., Perlepe K., Lambrou D., Sirimarco G., Strambo D., Eskandari A., Karagkiozi E., Vemmou A., Koroboki E., Manios E., Makaritsis K., Vemmos K., Michel P. (2019)
      Background: We aimed to assess the prevalence and degree of overlap of potential embolic sources (PES) in patients with embolic stroke of undetermined source (ESUS). Methods and Results: In a pooled data set derived from ...
    • Risk Stratification for Recurrence and Mortality in Embolic Stroke of Undetermined Source 

      Ntaios G., Vemmos K., Lip G.Y.H., Koroboki E., Manios E., Vemmou A., Rodríguez-Campello A., Cuadrado-Godia E., Giralt-Steinhauer E., Arnao V., Caso V., Paciaroni M., Diez-Tejedor E., Fuentes B., Pérez Lucas J., Arauz A., Ameriso S.F., Hawkes M.A., Pertierra L., Gómez-Schneider M., Bandini F., Chavarria Cano B., Iglesias Mohedano A.M., García Pastor A., Gil-Núñez A., Putaala J., Tatlisumak T., Barboza M.A., Athanasakis G., Makaritsis K., Papavasileiou V. (2016)
      Background and Purpose - The risk of stroke recurrence in patients with Embolic Stroke of Undetermined Source (ESUS) is high, and the optimal antithrombotic strategy for secondary prevention is unclear. We investigated ...
    • Statin treatment and outcomes after embolic stroke of undetermined source 

      Sagris D., Perlepe K., Leventis I., Samara S., Manios E., Korompoki E., Makaritsis K., Milionis H., Vemmos K., Ntaios G. (2021)
      The association of low-density lipoprotein cholesterol lowering with outcomes in embolic stroke of undetermined source (ESUS) patients is unclear. In these patients we aimed to assess the effect of statin on stroke recurrence, ...
