    • Objective The prevalence of stroke is expected to increase partly because of prolonged life expectancy in the general population. The objective of this study was to investigate trends in the prevalence of patients hospitalized with ischemic stroke (IS) in Sweden from 1995-2010. The Swedish inpatient and cause-specific death registries were used to estimate the absolute numbers and prevalence of patients who were hospitalized with and survived an IS from 1995-2010. The overall number of IS increased from 129,418 in 1995 to 148,778 in 2010. In 1995, the prevalence of IS was 189 patients per 10,000 population. An increase in overall prevalence was observed until 2000, and then it remained stable, followed by a decline with an annual percentage change of (APC)-0.8% (95% CI -1.0 to 0.6) and with a final prevalence of 199 patients per 10,000 population in 2010. The prevalence of IS in people aged <45 years increased from 6.4 in 1995 to 7.6 patients per 10,000 population in 2010, with an APC of 2.1% (95% CI 0.9 to 3.4) from 1995-1998 and 0.7% (95% CI 0.6-0.9) from 1998-2010. Among those aged 45-54 years, the prevalence rose through the mid to late 1990s, followed by a slight decrease (APC:-0.7%, 95% CI -1.1 to -0.4) until 2006 and then remained stable with a prevalence of 43.8 patients per 10,000 population in 2010. Among >= 85 years, there was a minor decrease (APC: -0.3%, 95% CI -0.5 to -0.1) in overall prevalence after 2002 from 1481 to 1453 patients per 10,000 population in 2010. The overall prevalence of IS increased until 2000, but then remained stable followed by a slight decline. However, the prevalence of IS in the young increased through the study period. The absolute number of IS survivors has markedly increased, mainly because of demographic changes.

  • Trends in risk of recurrence after the first ischemic stroke in adults younger than 55 years of age in Sweden
  • 2016
  • In: International Journal of Stroke. - : SAGE Publications. - 1747-4930 .- 1747-4949. ; 11:1, s. 52-61
  • Journal article (peer-reviewed)abstract
    • Background: Previous studies on stroke recurrence in younger adults often contain small sample size which makes it difficult to study trends in stroke recurrence over a long period of time. Aims: The aim of the present study was to investigate temporal trends in the risk of recurrence in younger patients with a first ischemic stroke. Methods: All men and women aged 18-54 years who had survived at least 28 days after a first ischemic stroke from 1987 to 2006 were identified in the Swedish Inpatient Register. The patients were stratified into four 5-year periods according to their admission period and were followed up for a total of four years after the index event with regard to recurrent ischemic stroke. A Cox regression model was used to analyze the risk of recurrent ischemic stroke. Results: Of the 17,149 ischemic stroke patients who were identified, 2432 (14.2%) had a recurrent ischemic stroke event within four years. From the first to the last periods (1987-1991 versus 2002-2006), the four-year risk of recurrent ischemic stroke decreased by 55% (hazard ratio 0.45, 95% confidence interval 0.39-0.53) in men and 59% (hazard ratio 0.41, 95% confidence interval, 0.33-0.50) in women. The cumulative four-year risk was 11.8% (95% CI 10.55-13.25) in men and 9.8% (95% CI 8.40-11.46) in women during the last five-year period (2002-2006). Conclusions: The risk of recurrence among younger ischemic stroke patients has decreased over the past 20 years. Despite these improvements, younger patients are still at a high risk for recurrent ischemic stroke.

  • Occupational status and incidences of ischemic and hemorrhagic stroke in Swedish men: a population-based 35-year prospective follow-up study
  • 2013
  • In: European Journal of Epidemiology. - : Springer Science and Business Media LLC. - 0393-2990 .- 1573-7284. ; 28:8, s. 697-704
  • Journal article (peer-reviewed)abstract
    • This study examined variations in stroke incidence across occupational classes over a 35-year follow-up period. We analyzed a random population-based sample of 6,994 men aged 47-56 years at baseline without prior history of stroke. Standardized incidence rates, subdistribution hazard ratios (SHRs) from competing risk regressions and cumulative incidence were calculated, after accounting for risk of death attributed to causes other than stroke. A total of 1,442 strokes were identified over the 35-year period with crude incidences of 5.50 (ischemic) and 1.16 (hemorrhagic) per 1,000 person-years. In the whole group, occupational class was not associated with either ischemic or hemorrhagic stroke. However, older men (>/=51 years at baseline) with unskilled manual occupations had a significantly lower risk of ischemic stroke than those with high officials (referent). No association between occupation and stroke of either type was detected for men younger than 51 years. There was an inverse and graded risk of death from causes other than stroke; men in high official positions had the lowest cumulative risk and unskilled manual workers had the highest risk (P < 0.0001). The association between occupation and ischemic stroke in older men persisted after accounting for competing risks of death (SHR 0.62; 95 % CI 0.46-0.84). In conclusion, low socioeconomic status was not associated with an increased risk of incident hemorrhagic or ischemic stroke. Older men with the lowest occupational status i.e. unskilled manual had a significantly lower risk of ischemic stroke, even after controlling for other risk factors and competing risks of death.

  • Living alone predicts mortality in patients with ischemic stroke before 70 years of age: a long-term prospective follow-up study
  • 2016
  • In: BMC neurology. - : Springer Science and Business Media LLC. - 1471-2377 .- 1471-2377. ; 16
  • Journal article (peer-reviewed)abstract
    • BACKGROUND: Living alone is associated with increased mortality after myocardial infarction but little data is available about whether this applies to prognosis after stroke. We aimed to examine the association between living situation and long-term mortality in patients with ischemic stroke and a control group, and to explore whether this association is modified by patient gender. METHODS: This is a prospective case-control study of 600 patients with ischemic stroke before 70 years of age and 600 age- and sex-matched controls who have been included in the Sahlgrenska Study on Ischemic Stroke. Mortality data were collected through national registers and medical records. We used Cox regression models for identifying predictors of mortality. RESULTS: In the entire sample, mean age was 57 years, proportion of males 64 %, proportion living alone 28 %, and median follow-up 8.6 years. Mortality rates were 36 % among patients living alone, 17 % among cohabitant patients, 15 % among controls living alone, and 9 % among cohabitant controls. Living alone was an independent predictor of all-cause mortality in cases after adjustment for stroke severity, stroke subtype, and vascular risk factors including physical activity, alcohol consumption, and socioeconomic status. A significant interaction was found between gender and living situation; the adjusted hazard ratio for mortality was 3.47 (95 % Confidence Interval 2.13-5.65) in male patients living alone, whereas no significant association was observed in women. Living alone was also a predictor of vascular mortality among cases and of all-cause mortality among controls. CONCLUSIONS: Living alone is associated with increased long-term mortality after ischemic stroke in men. Further prospective studies are needed to confirm the observed gender difference and to identify modifiable factors underlying this increased risk.

  • Twenty-Four-Year Trends in the Incidence of Ischemic Stroke in Sweden From 1987 to 2010
  • 2013
  • In: Stroke. - 0039-2499. ; 44:9, s. 2388-93
  • Journal article (peer-reviewed)abstract
    • BACKGROUND AND PURPOSE: The incidence of stroke in Sweden increased between 1989 and 2000 among people aged 65 years are lacking. METHODS: Through the Swedish Hospital Discharge and Cause of Death registries, we identified all cases of nonfatal and fatal ischemic stroke (IS) among people aged 18 to 84 years during 1987-2010 in Sweden. RESULTS: Of the 391 081 stroke cases identified, 1.6% were 18 to 44 years, 16.7% were 45 to 64 years, and 81.7% were 65 to 84 years. Among people aged 18 to 44 years, there was a continuous increase in the incidence of stroke of 1.3% (95% confidence interval, 0.8%-1.8%) per year for men and 1.6% (1.0%-2.3%) per year for women. Among men and women aged 45 to 64 years, slightly declining rates were observed from the late 1990s, with a mean annual decrease of 0.4% (0.1%-0.7%) among men and 0.6% (0.2%-1.0%) among women. Among men aged 65 to 84 years, a decrease of 3.7% in IS (3.4%-4.0%) per year was observed from the late 1990s. This was more marked in women, where an initial decrease of 2.5% (2.1%-2.9%) per year was followed by an accelerated decrease of 5.1% (4.4%-5.8%) after 2005. Mortality from IS decreased markedly in all age groups.Conclusions-The incidenceof IS in elderly people in Sweden is now decreasing, whereas the decline in IS incidence in the middle-aged people is much less steep. The increasing incidence of stroke in the young, particularly if carried forward to an older age, is concerning.

  • Body mass index in mid-life is associated with a first stroke in men: a prospective population study over 28 years
  • 2004
  • In: Stroke. - 1524-4628. ; 35:12, s. 2764-9
  • Journal article (peer-reviewed)abstract
    • BACKGROUND AND PURPOSE: Data on the association between obesity and stroke are still limited. We examined the possible association between mid-life body mass index (BMI) and risk of stroke in the prospective Multifactor Primary Prevention Study in Goteborg, Sweden. METHODS: 7402 apparently healthy men aged 47 to 55 at baseline were followed-up over a 28-year period. Incidence of fatal and nonfatal stroke was recorded in a local stroke registry through the Swedish National Register on Cause of Death and the Swedish Hospital Discharge Registry. RESULTS: A total of 873 first strokes were recorded, including 495 ischemic, 144 hemorrhagic, and 234 unspecified strokes. Compared with men with low normal weight (BMI, 20.0 to 22.49 kg/m2), men with BMI >30.0 kg/m2 had a multiple adjusted hazard ratio of 1.93 (95% CI, 1.44 to 2.58) for total stroke, 1.78 (95% CI, 1.22 to 2.60) for ischemic stroke, and 3.91 (95% CI, 2.10 to 7.27) for unspecified stroke. There was no significant association between BMI and hemorrhagic stroke. Adjustment for potential mediators, eg, hypertension, diabetes and serum cholesterol levels, attenuated but did not eliminate the risk. CONCLUSIONS: In this prospective population-based study of men, increased BMI in mid-life was associated with an increased risk for total, ischemic, and unspecified stroke, but not with hemorrhagic stroke. The result supports the role of mid-life BMI as a risk factor for stroke later in life and suggests a differentiated effect on stroke subtypes.

  • Family history in ischemic stroke before 70 years of age: the Sahlgrenska Academy Study on Ischemic Stroke
  • 2005
  • In: Stroke. - 1524-4628. ; 36:7, s. 1383-7
  • Journal article (peer-reviewed)abstract
    • BACKGROUND AND PURPOSE: Results from twin and family history studies of ischemic stroke suggest that future molecular genetic studies should focus on strictly defined stroke subtypes and younger cases. Accordingly, we investigated stroke subtypes, vascular risk factors, and family history in a large study of patients with ischemic stroke onset before age 70 years. METHODS: Six hundred consecutive white participants with ischemic stroke (18 to 69 years) and 600 age- and sex-matched controls were examined for vascular risk factors and family history of stroke and myocardial infarction (MI). Stroke subtype was defined using Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria. RESULTS: Family history of stroke was associated with overall ischemic stroke (multivariate odds ratio [OR], 1.75; 95% confidence interval [CI], 1.26 to 2.43), large-vessel disease (LVD) (OR, 1.88; 95% CI, 1.02 to 3.44), small-vessel disease (SVD, OR, 1.79; 95% CI, 1.13 to 2.84), and cryptogenic stroke (OR, 1.70; 95% CI, 1.13 to 2.56), but not with cardioembolic stroke. Family history of MI was strongly associated with LVD (OR, 3.25; 95% CI, 1.74 to 6.07), whereas no significant association were observed for other subtypes. We also found an independent association between family history of stroke and a favorable outcome after 3 months. CONCLUSION: Family history of stroke is an independent risk factor for ischemic stroke with onset before age 70 years. For the first time to our knowledge, we report this association not only for LVD and SVD but also for cryptogenic stroke, implying that future studies of the genetics of ischemic stroke should target these 3 subtypes.

  • Self-perceived psychological stress and ischemic stroke: a case-control study.
  • 2009
  • In: BMC medicine. - : Springer Science and Business Media LLC. - 1741-7015. ; 7
  • Journal article (peer-reviewed)abstract
    • BACKGROUND: A growing body of evidence suggests that psychological stress contributes to coronary artery disease. However, associations between stress and stroke are less clear. In this study, we investigated the possible association between ischemic stroke and self-perceived psychological stress, as measured by a single-item questionnaire, previously reported to be associated with myocardial infarction. METHODS: In the Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS), 600 consecutive patients with acute ischemic stroke (aged 18 to 69 years) and 600 age-matched and sex-matched population controls were recruited. Ischemic stroke subtype was determined according to Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria. Self-perceived psychological stress preceding stroke was assessed retrospectively using a single-item questionnaire. RESULTS: Permanent self-perceived psychological stress during the last year or longer was independently associated with overall ischemic stroke (multivariate adjusted odds ratio (OR) 3.49, 95% confidence interval (CI) 2.06 to 5.93). Analyses by stroke subtype showed that this association was present for large vessel disease (OR 3.91, 95% CI 1.58 to 9.67), small vessel disease (OR 3.20, 95% CI 1.64 to 6.24), and cryptogenic stroke (OR 4.03, 95% CI 2.34 to 6.95), but not for cardioembolic stroke (OR 1.48, 95% CI 0.64 to 3.39). CONCLUSION: In this case-control study, we found an independent association between self-perceived psychological stress and ischemic stroke. A novel finding was that this association differed by ischemic stroke subtype. Our results emphasize the need for further prospective studies addressing the potential role for psychological stress as a risk factor for ischemic stroke. In such studies ischemic stroke subtypes should be taken into consideration.

  • Genetic variation at the human tissue-type plasminogen activator (tPA) locus: haplotypes and analysis of association to plasma levels of tPA.
  • 2003
  • In: European journal of human genetics : EJHG. - : Springer Science and Business Media LLC. - 1018-4813 .- 1476-5438. ; 11:8, s. 603-10
  • Journal article (peer-reviewed)abstract
    • Tissue-type plasminogen activator (tPA) plays a key role in thrombus dissolution and plasma levels of tPA have been associated with cardiovascular disease. We have previously resequenced regulatory and coding regions of the human tPA gene (PLAT) and identified eight single-nucleotide polymorphisms (SNPs). In a small experimental study, four common variants were associated with invasively determined vascular tPA release rates. The aim of the present study was to investigate whether there is an association between genetic variants at this locus and plasma levels of tPA. To this end, 240 Swedish individuals without cardiovascular disease were typed for the eight SNPs and an Alu insertion polymorphism at the PLAT locus, as well as for a polymorphism in the plasminogen activator inhibitor type 1 (PAI-1) promoter (PAI-1 -675 4G>5G). Stepwise regression analysis, with established predictors of plasma tPA including plasma PAI-1 and genetic variants, showed that neither genotypes nor haplotypes were major contributors to plasma tPA. The results also showed that the level of linkage disequilibrium was high at the PLAT locus, as demonstrated by the fact that only three haplotypes had a frequency above 5%. In conclusion, in the present study neither genetic variation at the PLAT locus nor the PAI-1 -675 4G>5G polymorphism was strong predictors of plasma tPA levels, which suggests that variations in other genes contribute to the heritability of this phenotype. The results also show that three haplotypes at the PLAT locus accounted for nearly 90% of the chromosomes and that they could be defined by typing only two SNPs.
