Fundamento. Describir la prevalencia de accidentes cerebrovasculares agudos (ACV) y los factores de riesgo trombótico existentes en pacientes diagnosticados de síndrome antifosfolipídico primario (SAFP) y comparar este grupo con el de los pacientes que estando afectados de SAFP no presentaron ACV. Material y métodos. Se revisaron retrospectivamente los datos de 30 pacientes diagnosticados consecutivamente de SAFP. Se cuantificaron los episodios de ACV y se determinaron otros factores de riesgo cardiovascular. Resultados. El 30% de los pacientes (9/30) presentaron uno o más ACV. Al comparar la existencia de otros factores de riesgo cardiovascular en ambos grupos no se encontraron diferencias significativas. Conclusiones. En los pacientes jóvenes que sufren un ACV deben determinarse anticuerpos antifosfolipídicos, a pesar de que coexistan otros factores de riesgo cardiovascular.

Objective. To report the prevalence of acute cerebrovascular accidents (ACVA) and risk factors for thrombosis among patients diagnosed of primary antiphospholipid syndrome (PAPLS) and to compare this group with that of patients with PAPLS but not ACVA. Patients and methods. Retrospective data analysis of 30 patients consecutively diagnosed of PAPLS. Episodes of ACVA were quantitated and other cardiovascular risk factors were determined. Results. Therty percent of patients (9/30) had one or more ACVA. No significant differences were found when the presence of other cardiovascular risk factors in both groups was compared. Conclusions. Antiphospholipid antibodies in young patients with ACVA should be determined, although some other cardiovascular risk factors may coexist.
