  • 2010
  • Ingår i: Cerebrovascular Diseases. - : S. Karger AG. - 1015-9770 .- 1421-9786. ; 30:2, s. 114-119

    • BACKGROUND: Reported improvements in outcome in stroke patients treated in hospital are often attributed to advances in stroke care. However, secular trends in patient characteristics that are present already on admission to hospital may also contribute to improved outcome. METHODS: Time trends for baseline data (289,854 stroke admittances) in Riks-Stroke, the Swedish national quality register for stroke care, were analyzed for the years 1995 through 2008. The following data were included: number of strokes for each year, age, sex, risk factors, stroke subtype, stroke severity, functional status and need of external home service before the stroke. RESULTS: The number of annually reported strokes increased until 2005. The proportion of recurrent strokes decreased from 28.0 to 25.9%. The mean age at first-ever stroke increased in women, but not in men. The proportion of smokers dropped, and the proportion of patients who had treated hypertension increased. The stroke severity decreased in men. The prestroke functional status (walking, dressing, toileting) improved in both sexes over these years. More patients lived alone in 2008 than in 1995, and more had home help service. CONCLUSIONS: Many baseline parameters in Riks-Stroke have changed over the years. This has consequences for the interpretation of outcome data. Some changes may be due to inclusion bias, others due to alterations in general health, evolution of vascular risk factors or demographics.

  • Functional outcome 3 months after stroke predicts long-term survival
  • 2008
  • Ingår i: Cerebrovascular Diseases. - : S. Karger AG. - 1421-9786 .- 1015-9770. ; 25:5, s. 423-429
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: When reporting stroke survival and prognostic factors with a possible effect on outcome, the starting point for the observation of a clinical cohort usually is the onset of stroke or the acute admission of a patient. Thus, acute and early mortality inflict prognosis on long-term outcome. In order to give a more robust analysis of long-term survival after the acute period we chose to start our observation with 3-month survivors. Methods: We used data from Riks-Stroke, the Swedish quality register for stroke care, together with survival information from the Swedish population register to explore the influence of disability level 3 months after stroke on long-term survival. The main analysis included 15,959 stroke patients, registered during 2001-2002, who had been independent in primary activities of daily living before stroke, had suffered an ischaemic or a haemorrhagic stroke and reported no previous stroke. Results: Impaired functional outcome after stroke was an independent predictor of poor survival. Patients with modified Rankin scale (mRS) grades 3, 4 and 5 had hazard ratios of 1.7, 2.5 and 3.8, respectively, as compared with patients with lower mRS grades. In addition to high mRS, male sex, high age, diabetes, smoking, hypertension therapy at stroke onset, atrial fibrillation and depressed mood were also recognized as significant predictors of poor survival using a multiple Cox regression model. Conclusion: The influence of disability on survival is stronger than that of several other well-known prognostic factors. This finding indicates that any intervention in the acute phase that may improve functional status at 3 months will also have favourable secondary effects on survival in the long term.

  • The disparity in long-term survival after a first stroke in patients with and without diabetes persists : the Northern Sweden MONICA Study
  • 2012
  • Ingår i: Cerebrovascular Diseases. - Basel : S. Karger. - 1015-9770 .- 1421-9786. ; 34:2, s. 153-160

    • Background: Diabetes is an established risk factor for stroke. Compared to nondiabetic patients, diabetic patients also have an increased risk of new vascular events and death after stroke. We analyzed how differences in long-term survival between diabetic and nondiabetic stroke patients have changed over time, and if differences varied with respect to sex and age.Methods: This population-based study included 12,375 first-ever stroke patients, 25-74 years old, who were registered in the Northern Sweden MONICA Stroke Registry 1985-2005. Uniform diagnostic criteria for stroke case ascertainment were used throughout the study period. The diagnosis of diabetes was based on medical records or diabetes diagnosed during the acute stroke event. Patients were separated into four cohorts according to year of stroke and followed for survival until August 30, 2008.Results: The diabetes prevalence at stroke onset was 21%, similar in men and women, and remained stable throughout the study period. The diabetic patients were an average of 2 years older, more often nonsmokers and more likely to have antihypertensive treatment, antithrombotics, atrial fibrillation, and a history of myocardial infarction or transient ischemic attack than the nondiabetic patients. The total follow-up time was 86,086 patient-years during which a total of 1,930 (75.7%) of the diabetic patients and 5,744 (58.5%) of the nondiabetic patients died (p < 0.001). Median survival was 60 months (95% CI: 57-64) in diabetic patients and 117 months (113-120) in the nondiabetic patients. Survival improved significantly in both groups (p < 0.001). A Cox regression, adjusting for possible confounders (age, sex, antihypertensive medication, antithrombotics or other thrombolytic agents, history of myocardial infarction, type of stroke, diabetes, cohort and the diabetes-by-sex, diabetes-by-age and diabetes-by-cohort interactions), showed a hazard ratio of 1.67 (1.58-1.76) comparing survival in diabetic versus nondiabetic patients. The reduced survival in diabetic stroke patients was more pronounced in women (p = 0.02) and younger patients (p < 0.001). There was a tendency that the difference in survival decreased between the earlier cohorts and the 2000-2005 cohort, but the test for interaction did not reach statistical significance (p = 0.08).Conclusion: Long-term survival after a first stroke has improved in both diabetic and nondiabetic patients. Survival is markedly lower in diabetics, especially in women and younger patients, and the disparity persisted over 24 years. Decreasing the disparity in stroke survival is a challenge for stroke and diabetes care. New treatment methods in combination with intense secondary prevention in diabetic patients, especially in younger women, are needed.

  • Reduced inequality in access to stroke unit care over time : A 15-year follow-up of socioeconomic disparities in Sweden
  • 2013
  • Ingår i: Cerebrovascular Diseases. - : S. Karger AG. - 1015-9770 .- 1421-9786. ; 36:5-6, s. 407-411
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Despite the compelling scientific evidence on the superiority of stroke unit care, far from all acute stroke patients have access to stroke unit care. In congruence with what has been observed when other new methods are introduced in health care, we hypothesized that there has been an inequality in the buildup phase of stroke units but that the gradients between patient groups have decreased as the total capacity of stroke unit care has increased. The purpose of this study was to explore if patients in a national sample who were socioeconomically disadvantaged (low education or low income) had reduced access to stroke unit care and if differences varied over time. Methods: All patients 18-74 years of age registered between 1995 and 2009 in Riks-Stroke, the Swedish stroke register, were included. The Stroke Unit Trialists' definition of a stroke unit has been adopted by Riks-Stroke and hospitals participating in the registry. Basic patient characteristics, stroke risk factors, process and outcome variables are recorded in Riks-Stroke. Socioeconomic data were accessed from Statistics Sweden. Multiple logistic regression analyses were used to calculate odds ratios (ORs) for stroke unit care between prespecified patient subgroups. Results: A total of 319,240 stroke patients were included in Riks-Stroke during the years 1995-2009, and 124,173 were aged between 18 and 74 years; they were included in the final analyses. After adjustment for confounders in a multiple regression model, women were treated in stroke units slightly less often [OR 0.97, 95% confidence interval (CI) 0.95-0.99]. There were no statistically significant associations between stroke unit care and age or between stroke unit care and cohabiting or living alone. The highest level of education predicted access to stroke unit care (secondary vs. primary school: OR 1.04, 95% CI 1.01-1.07; university vs. primary school: OR 1.06, 95% CI 1.02-1.10). Differences according to level of education diminished over time (p = 0.001). Income was not independently associated with stroke unit care, and over time the proportion of patients treated in stroke units increased at a similar rate in all income groups (p = 0.12). Conclusions: Even in a country with modest socioeconomic differences in the general population and public financing of all acute hospital care, socioeconomic inequalities in access to stroke unit care were evident during the early years, but they diminished as the total capacity for stroke unit care increased.

  • Risk factors assessed in adolescence and the later risk of stroke in men : a 33-year follow-up study
  • 2015
  • Ingår i: Cerebrovascular Diseases. - : S. Karger AG. - 1015-9770 .- 1421-9786. ; 39:1, s. 63-71
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Stroke is a common cause of death, and a leading contributor to long-term disability. The cost associated with the disease is great. Several modifiable risk factors for stroke have been found in older cohorts; however, no study to date has investigated the effects of these risk factors from late adolescence.METHODS: The study cohort comprised 811,579 Swedish men (mean age, 18 years) that participated in the mandatory military conscription service in Sweden between 1969 and 1986. Some risk factors for stroke, such as body mass index, systolic and diastolic blood pressure, and cognitive function, were assessed at conscription. Aerobic fitness was also assessed at conscription, using a braked ergometer cycle test. Other risk factors for stroke, including stroke in subjects' parents, and socioeconomic factors including highest achieved level of education and annual income 15 years after conscription, were collected through national register linkage using the personal identification number. Stroke diagnosis among the study participants was tracked in the National Hospital Discharge Patient Register.RESULTS: During a median follow-up period of 33 years 6,180 ischemic strokes and 2,104 hemorrhagic strokes were diagnosed in the cohort at a mean age of 47.9 years. Strong independent risk factors (all p <1.0 × 10-(6)) for ischemic stroke included low aerobic fitness (hazard ratio [HR], 0.84 per standard deviation [SD] increase), high BMI (HR, 1.15 per SD increase), diabetes (HR, 2.85), alcohol intoxication (HR, 1.93), low annual income (HR, 0.85 per SD decrease), and stroke in the mother (HR, 1.31). Similar risk factors were found for hemorrhagic stroke including low aerobic fitness (HR, 0.82 per SD increase), high BMI (HR, 1.18 per SD increase) alcohol intoxication (HR, 2.92), diabetes (HR, 2.06), and low annual income (HR, 0.75). The population attributable risks associated with all evaluated risk factors were 69% for ischemic stroke and 88% for hemorrhagic stroke (p < 0.001 for both).CONCLUSIONS: In the present study we have shown that several known risk factors for stroke are present already in late adolescence, and that they are independent of each other. The strongest risk factors were low physical fitness, high BMI, diabetes, low annual income and a maternal history of stroke. Several of the aforementioned risk factors are potentially modifiable.

  • Systemic antibodies to the leukotoxin of the oral pathogen Actinobacillus actinomycetemcomitans correlate negatively with stroke in women
  • 2005
  • Ingår i: Cerebrovascular Diseases. - Basel : Karger. - 1015-9770 .- 1421-9786. ; 20:4, s. 226-232
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Chronic infections and associated inflammatory markers are suggested risk factors for cardiovascular diseases (CVD) and stroke. The proinflammatory cytokine interleukin (IL)-1β is suggested to play a role in the regulation of local inflammatory responses in both CVD and periodontitis. The leukotoxin from the periodontal pathogen Actinobacillus actinomycetemcomitans has recently been shown to cause abundant secretion of IL-1β  from macrophages. The aim of the present study was to compare the prevalence of systemic antibodies to A. actinomycetemcomitansleukotoxin in stroke cases (n = 273) and matched controls (n = 546) in an incident case-control study nested within the Northern Sweden MONICA and Västerbotten Intervention cohorts. Methods: Antibodies to A. actinomycetemcomitans leukotoxin were analyzed in a bioassay with HL-60 cells (leukocytes), purified A. actinomycetemcomitans leukotoxin, and plasma. Plasma samples which inhibited lactate dehydrogenase release from leukotoxin-lysed cells by ≥50% were classified as antibody positive. Results: Antibodies to A. actinomycetemcomitans leukotoxin were detected in 18.8% of the women and 15.2% of the men. Women with those antibodies had a significantly decreased risk for stroke (OR = 0.28, 95% CI: 0.13–0.59), but not men (OR = 0.88, 95% CI: 0.52–1.51). Conclusion: The immunoreactivity to A. actinomycetemcomitans leukotoxin correlates negatively with a future stroke in woman, but not in men. Further studies are needed to explain the underlying mechanisms, as well as the biological relevance of this finding.
