- Background-Recent studies have shown an increasing prevalence of vascular risk factors in young adults with ischemic stroke (IS). However, the strength of the association between all vascular risk factors and early-onset IS has not been fully established. Methods and Results-We compared 961 patients with a first-ever IS at 25 to 49 years to 1403 frequency-matched stroke-free controls from a population-based cohort study (FINRISK). Assessed risk factors included an active malignancy, atrial fibrillation, cardiovascular disease, current smoking status, a family history of stroke, high low-density lipoprotein cholesterol, high triglycerides, low high-density lipoprotein cholesterol, hypertension, and type 1 and type 2 diabetes mellitus. We performed subgroup analyses based on age, sex, and IS etiology. In a fully adjusted multivariable logistic regression analysis, significant risk factors for IS consisted of atrial fibrillation (odds ratio [OR], 10.43; 95% confidence interval [CI], 2.33–46.77], cardiovascular disease (OR, 8.01; 95% CI, 3.09–20.78), type 1 diabetes mellitus (OR, 6.72; 95% CI, 3.15–14.33), type 2 diabetes mellitus (OR, 2.31; 95% CI, 1.35–3.95), low high-density lipoprotein cholesterol (OR, 1.81; 95% CI, 1.37–2.40), current smoking status (OR, 1.81; 95% CI, 1.50–2.17), hypertension (OR, 1.43; 95% CI, 1.17–1.75), and a family history of stroke (OR, 1.37; 95% CI, 1.04–1.82). High low-density lipoprotein cholesterol exhibited an inverse association with IS. In the subgroup analyses, the most consistent associations appeared for current smoking status and type 1 diabetes mellitus. Conclusions-Our study establishes the associations between 11 vascular risk factors and early-onset IS, among which atrial fibrillation, cardiovascular disease, and both type 1 and 2 diabetes mellitus in particular showed strong associations. © 2018 The Authors.

- Background and purposeBlood pressure (BP) levels in acute intracerebral hemorrhage (ICH) and mortality have not been thoroughly studied in the young. MethodsThe relationship between BP and mortality was assessed in consecutive patients with first-ever, non-traumatic acute ICH at 50 years of age, enrolled in the Helsinki ICH Young Study. BP parameters included systolic BP (SBP), diastolic BP (DBP), mean arterial pressure and pulse pressure (SBP - DBP) at admission and 24 h, and delta (admission-24 h) BP parameters. Outcome measures were 3-month and long-term mortalities, adjusted for demographics and ICH score parameters for short-term and cardiovascular risk factors for long-term prognostics. Cox regression models were used to assess independent BP parameters associated with mortality. ResultsOf our 334 patients (61% male), 92 (27%) had pre-stroke hypertension and 54 (16%) used antihypertensive treatment. The follow-up extended to 17 years with a median of 12 (interquartile range, 9.65-14.7) years. Both 3-month (n = 56; 16%) and long-term (n = 97; 29%) mortalities were associated with significantly higher admission SBP and mean arterial pressure levels, but not with 24-h BP levels, compared with survivors. Patients with SBP 160 mmHg (n = 156; 46%) had a significantly higher mortality rate (n = 59, 17% vs. n = 38, 11%; P = 0.001) and died earlier (9.6; 95% confidence interval, 2.9-12.9 years vs. 11.3; 95% confidence interval, 8.1-13.9 years; P = 0.001) within the follow-up period. In multivariable analyses, admission SBP 160 mmHg was independently associated with both 3-month (hazard ratio, 2.50; 95% confidence interval, 1.19-5.24; P < 0.05) and long-term (hazard ratio, 2.02; 95% confidence interval, 1.18-3.43; P < 0.01) mortalities. ConclusionsIn young patients with ICH, acute-phase SBP levels 160 mmHg are independently associated with increased mortality.
