[Cerebral infarction in young patients: clinical characteristics and evolution in an Argentine cohort].

Introduction: Stroke (CVA) in young adults comprises approximately 10% of all cerebrovascular events. The information available on the recurrence of a new event in this population and particularly in Latin America is limited. Our objective was to examine the presence of stroke recurrence after having presented a stroke.
Methods: A retrospective cohort study was carried out, including patients with arterial cerebral infarctions between the ages of 18 and 55, between January 2005 and May 2020. The main outcome was the recurrence of a cerebrovascular attack.
Results: 138 patients were included during a median follow-up of 24 months. The 52.2% (n = 72) were male patients and 73.4% (n = 94) had an initial NIHSS score of less than 4. The 38% (n = 52) had a history of arterial hypertension and 13, 1% (n = 18) history of previous stroke / TIA. 13% (n = 18) presented recurrence during their follow-up.
Discussion: The recurrence of neurovascular events occurs predominantly in patients with a history of previous stroke/TIA, probably secondary to diseases that are difficult to diagnose.
