- Parenchymal hematoma (PH) following intravenous thrombolysis (IVT) in ischemic stroke can occur either within the ischemic area (iPH) or as a remote PH (rPH). The latter could be, at least partly, related to cerebral amyloid angiopathy, which belongs to the continuum of cerebral small vessel disease. We hypothesized that cerebral white matter lesions (WMLs)-an imaging surrogate of small vessel disease-are associated with a higher rate of rPH.We analyzed 2,485 consecutive patients treated with IVT at the Helsinki University Hospital. Blennow rating scale of 5 to 6 points on baseline computed tomographic head scans was considered as severe WMLs. An rPH was defined as hemorrhage that-contrary to iPH-appears in brain regions without visible ischemic damage and is clinically not related to the symptomatic acute lesion site. The associations between severe WMLs and pure rPH versus no PH, pure iPH versus no PH, and pure rPH versus pure iPH were studied in multivariate logistic regression models.rPHs were mostly (74%) located in lobar regions. After adjustments, the presence of severe WMLs was associated with pure rPH (odds ratio [OR] = 6.79, 95% confidence interval [CI] = 2.57-17.94) but not with pure iPH (OR = 1.45, 95% CI = 0.83-2.53) when compared to patients with no PH. In direct comparison of pure rPH with pure iPH, severe cerebral WMLs were further associated with higher iPH rates (OR = 3.60, 95% CI = 1.06-12.19).Severe cerebral WMLs were associated with post-thrombolytic rPH but not with iPH within the ischemic area.

- Background and Purpose-Although many stroke patients are young or middle-aged, risk factor profiles in these age groups are poorly understood. Methods-The Stroke in Young Fabry Patients (sifap1) study prospectively recruited a large multinational European cohort of patients with cerebrovascular events aged 18 to 55 years to establish their prevalence of Fabry disease. In a secondary analysis of patients with ischemic stroke or transient ischemic attack, we studied age-and sex-specific prevalences of various risk factors. Results-Among 4467 patients (median age, 47 years; interquartile range, 40-51), the most frequent well-documented and modifiable risk factors were smoking (55.5%), physical inactivity (48.2%), arterial hypertension (46.6%), dyslipidemia (34.9%), and obesity (22.3%). Modifiable less well-documented or potentially modifiable risk factors like high-risk alcohol consumption (33.0%) and short sleep duration (20.6%) were more frequent in men, and migraine (26.5%) was more frequent in women. Women were more often physically inactive, most pronouncedly at ages <35 years (18-24: 38.2%; 25-34: 51.7%), and had high proportions of abdominal obesity at age 25 years or older (74%). Physical inactivity, arterial hypertension, dyslipidemia, obesity, and diabetes mellitus increased with age. Conclusions-In this large European cohort of young patients with acute ischemic cerebrovascular events, modifiable risk factors were highly prevalent, particularly in men and older patients. These data emphasize the need for vigorous primary and secondary prevention measures already in young populations targeting modifiable lifestyle vascular risk factors.
