description: <b>Background:</b> Knowledge on the use of secondary preventive medication in young adults is limited. <b>Methods:</b> We included 936 first-ever ischemic stroke 30-day survivors aged 15–49, enrolled in the Helsinki Young Stroke Registry, 1994–2007. Follow-up data until 2012 came from Finnish Care Register, Statistics Finland, and Social Insurance Institution of Finland. Usage thresholds were defined as non-users, low (prescription coverage &lt;30%), intermediate (30–80%) and high users (&gt;80%). Adjusted Cox regression allowed assessing the association of usage with all-cause mortality and recurrent vascular events. <b>Results:</b> Of our patients, 40.5% were non-users, 7.8% had low usage, 11.8% intermediate usage and 40.0% high usage. Median follow-up was 8.3 years. Compared to non-users, risk of mortality and recurrent stroke or TIA was lower for patients with low-intermediate (HR 0.40, 95% CI 0.22–0.65; HR 0.31, 95% CI 0.18–0.53) and high usage (HR 0.25, 95% CI 0.15–0.42; HR 0.30, 95% CI 0.19–0.46), after adjustment for confounders. <b>Conclusions:</b> Use of antihypertensives was suboptimal in one-third of patients in whom antihypertensives were initially prescribed. Users were at lower risk of mortality and recurrent stroke or TIA compared to non-users.Key MessagesThe use of antihypertensive medication is suboptimal in one-third of patients in whom antihypertensive medication was initially prescribed after ischemic stroke at young age.The risk of mortality and recurrent stroke or TIA is lower for users of antihypertensive medication after ischemic stroke at young age compared to non-users, after adjustment for relevant confounders including pre-existing hypertension and prior use of antihypertensive medication.Specific guidelines on antihypertensive medication use after ischemic stroke at young age are lacking. However, our results may motivate doctors and patients in gaining better usage of antihypertensive medication, since better usage was associated with more favorable outcome in this study.
