Retrospective analysis of a tertiary care centre of sex differences in risk factors, aetiology and short-term clinical outcome after revascularization treatment in young adults' ischemic stroke.

BACKGROUND AND OBJECTIVES

The incidence of ischemic stroke in young adults has increased substantially. There are limited data in the literature concerning the short-term clinical outcome in young adults with acute stroke after revascularization treatment. Due to the lack of available data on gender differences short-term clinical outcome, we designed the present study.

MATERIALS AND METHODS

We collected data from 127 patients aged 50 years or younger consecutively admitted to the Stroke-Unit of "Cardarelli" Hospital in Naples between August 2017 and September 2022 due to ischemic stroke. All of them underwent thrombolysis and/or endovascular treatment.

RESULTS AND CONCLUSIONS

Smoking, hypertension, and dyslipidemia emerged as the most prevalent risk factors. A gender-based analysis revealed that the history of stroke was the only statistically significant factor more frequently observed in the female group. The leading stroke etiology was "cardioembolism," succeeded by strokes of "other determined origin", "undetermined etiology," "large-artery atherosclerosis," and "small-artery occlusion." Concerning reperfusion therapy, intravenous thrombolysis ranked as the most utilized treatment, followed by "bridging" therapy (combining intravenous thrombolytic therapy with thrombectomy) and primary mechanical thrombectomy. Notably, the average NIHSS scores 7 days post-revascularization were lower among females compared to males, constituting a statistically significant distinction. Nevertheless, no statistically significant correlation surfaced between gender and treatment type in NIHSS mean values at admission, 2 hours, 24 hours post-revascularization, or 7 days post-revascularization. This suggests that the observed disparity in mean NIHSS score between male and female groups after 7 days may potentially stem from other factors, such as endogenous estrogens.
