  • Towards the genetic basis of cerebral venous thrombosis-the BEAST Consortium: a study protocol.
  • 2016

    • Cerebral venous thrombosis (CVT) is a rare cerebrovascular condition accounting for <1% of all stroke cases and mainly affects young adults. Its genetic aetiology is not clearly elucidated.To better understand the genetic basis of CVT, we have established an international biobank of CVT cases, Biorepository to Establish the Aetiology of Sinovenous Thrombosis (BEAST) which aims to recruit highly phenotyped cases initially of European descent and later from other populations. To date we have recruited 745 CVT cases from 12 research centres. As an initial step, the consortium plans to undertake a genome-wide association analysis of CVT using the Illumina Infinium HumanCoreExome BeadChip to assess the association and impact of common and low-frequency genetic variants on CVT risk by using a case-control study design. Replication will be performed to confirm putative findings. Furthermore, we aim to identify interactions of genetic variants with several environmental and comorbidity factors which will likely contribute to improve the understanding of the biological mechanisms underlying this complex disease.BEAST meets all ethical standards set by local institutional review boards for each of the participating sites. The research outcomes will be published in international peer-reviewed open-access journals with high impact and visibility. The results will be presented at national and international meetings to highlight the contributions into improving the understanding of the mechanisms underlying this uncommon but important disease. This international DNA repository will become an important resource for investigators in the field of haematological and vascular disorders.

  • Cerebral white matter lesions and post-thrombolytic remote parenchymal hemorrhage.
  • 2016
  • Ingår i: Annals of neurology. - 1531-8249. ; 80:4, s. 593-9

    • 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.

  • Are 12-lead ECG findings associated with the risk of cardiovascular events after ischemic stroke in young adults?
  • 2016
  • Ingår i: Annals of medicine. - 1365-2060. ; 48:7, s. 532-540
  • Tidskriftsartikel (refereegranskat)abstract
    • Ischemic stroke (IS) in a young patient is a disaster and recurrent cardiovascular events could add further impairment. Identifying patients with high risk of such events is therefore important. The prognostic relevance of ECG for this population is unknown.A total of 690 IS patients aged 15-49 years were included. A 12-lead ECG was obtained 1-14 d after the onset of stroke. We adjusted for demographic factors, comorbidities, and stroke characteristics, Cox regression models were used to identify independent ECG parameters associated with long-term risks of (1) any cardiovascular event, (2) cardiac events, and (3) recurrent stroke.Median follow-up time was 8.8 years. About 26.4% of patients experienced a cardiovascular event, 14.5% had cardiac events, and 14.6% recurrent strokes. ECG parameters associated with recurrent cardiovascular events were bundle branch blocks, P-terminal force, left ventricular hypertrophy, and a broader QRS complex. Furthermore, more leftward P-wave axis, prolonged QTc, and P-wave duration >120 ms were associated with increased risks of cardiac events. No ECG parameters were independently associated with recurrent stroke.A 12-lead ECG can be used for risk prediction of cardiovascular events but not for recurrent stroke in young IS patients. KEY MESSAGES ECG is an easy, inexpensive, and useful tool for identifying young ischemic stroke patients with a high risk for recurrent cardiovascular events and it has a statistically significant association with these events even after adjusting for confounding factors. Bundle branch blocks, P-terminal force, broader QRS complex, LVH according to Cornell voltage duration criteria, more leftward P-wave axis, prolonged QTc, and P-wave duration >120 ms are predictors for future cardiovascular or cardiac events in these patients. No ECG parameters were independently associated with recurrent stroke.
