  • Prostaglandin F2α formation is associated with mortality in a Swedish community-based cohort of older males
  • 2015
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 36:4, s. 238-243

    • AIMS: An increasing number of clinical studies highlight the importance of the inflammatory mediator prostaglandin F2α (PGF2α). Prostaglandin F2α activity has been suggested to play pivotal roles in the development of cardiovascular diseases and cancer. However, whether systemic PGF2α concentrations may signal mortality is unknown. The aim was to evaluate in vivo PGF2α formation, by measuring urinary 15-keto-dihydro-PGF2α, and mortality risk in a community setting.METHODS AND RESULTS: Urinary 15-keto-dihydro-PGF2α was measured in a Swedish population of 670 men (aged 77-78 years) and the participants were followed up for a median of 9.7 years (383 died, among them 156 of cardiovascular causes and 102 of cancer). In Cox regression models, urinary 15-keto-dihydro-PGF2α was significantly associated with cardiovascular mortality [multivariate hazard ratio (HR) for 1 SD increase of urinary 15-keto-dihydro-PGF2α: 1.18; 95% CI:1.04-1.34; P = 0.01) independent of established cardiovascular risk factors including C-reactive protein. Urinary 15-keto-dihydro-PGF2α was also independently associated with total mortality (multivariate HR for 1 SD increase of urinary 15-keto-dihydro-PGF2α: 1.11; 95% CI: 1.01-1.21; P = 0.03). The combination of 15-keto-dihydro-PGF2α concentrations above the median and high serum high-sensitive C-reactive protein (>3 mg/L) was independently associated with a two-fold increased risk of cancer and total mortality (P = 0.02 and P < 0.001, respectively).CONCLUSION: This is the first study to show that the inflammatory mediator PGF2α was independently associated with mortality and specifically cardiovascular mortality 10 years later. The results are in line with the emerging evidence of the importance of the inflammatory mediator PGF2α in fatal cardiovascular disease.

  • Trends in survival after cardiac arrest: a Swedish nationwide study over 30 years
  • 2022
  • Ingår i: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645.
  • Tidskriftsartikel (refereegranskat)abstract
    • AimsTrends in characteristics, management, and survival in out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) were studied in the Swedish Cardiopulmonary Resuscitation Registry (SCRR). Methods and resultsThe SCRR was used to study 106 296 cases of OHCA (1990–2020) and 30 032 cases of IHCA (2004–20) in whom resuscitation was attempted. In OHCA, survival increased from 5.7% in 1990 to 10.1% in 2011 and remained unchanged thereafter. Odds ratios [ORs, 95% confidence interval (CI)] for survival in 2017–20 vs. 1990–93 were 2.17 (1.93–2.43) overall, 2.36 (2.07–2.71) for men, and 1.67 (1.34–2.10) for women. Survival increased for all aetiologies, except trauma, suffocation, and drowning. OR for cardiac aetiology in 2017–20 vs. 1990–93 was 0.45 (0.42–0.48). Bystander cardiopulmonary resuscitation increased from 30.9% to 82.2%. Shockable rhythm decreased from 39.5% in 1990 to 17.4% in 2020. Use of targeted temperature management decreased from 42.1% (2010) to 18.2% (2020). In IHCA, OR for survival in 2017–20 vs. 2004–07 was 1.18 (1.06–1.31), showing a non-linear trend with probability of survival increasing by 46.6% during 2011–20. Myocardial ischaemia or infarction as aetiology decreased during 2004–20 from 67.4% to 28.3% [OR 0.30 (0.27–0.34)]. Shockable rhythm decreased from 37.4% to 23.0% [OR 0.57 (0.51–0.64)]. Approximately 90% of survivors (IHCA and OHCA) had no or mild neurological sequelae. ConclusionSurvival increased 2.2-fold in OHCA during 1990–2020 but without any improvement in the final decade, and 1.2-fold in IHCA during 2004–20, with rapid improvement the last decade. Cardiac aetiology and shockable rhythms were halved. Neurological outcome has not improved.

  • Improved outcome in Sweden after out-of-hospital cardiac arrest and possible association with improvements in every link in the chain of survival
  • 2015
  • Ingår i: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 36:14, s. 863-871
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To describe out-of-hospital cardiac arrest (OHCA) in Sweden from a long-term perspective in terms of changes in outcome and circumstances at resuscitation.Methods and results: All cases of OHCA (n = 59 926) reported to the Swedish Cardiac Arrest Register from 1992 to 2011 were included. The number of cases reported (n/100 000 person-years) increased from 27 (1992) to 52 (2011). Crew-witnessed cases, cardiopulmonary resuscitation prior to the arrival of the emergency medical service (EMS), and EMS response time increased (P < 0.0001). There was a decrease in the delay from collapse to calling for the EMS in all patients and from collapse to defibrillation among patients found in ventricular fibrillation (P< 0.0001). The proportion of patients found in ventricular fibrillation decreased from 35 to 25% (P < 0.0001). Thirty-day survival increased from 4.8 (1992) to 10.7% (2011) (P < 0.0001), particularly among patients found in a shockable rhythm and patients with return of spontaneous circulation (ROSC) at hospital admission. Among patients hospitalized with ROSC in 2008–2011, 41% underwent therapeutic hypothermia and 28% underwent percutaneous coronary intervention. Among 30-day survivors in 2008–2011, 94% had a cerebral performance category score of 1 or 2 at discharge from hospital and the results were even better if patients were found in a shockable rhythm.Conclusion: From a long-term perspective, 30-day survival after OHCA in Sweden more than doubled. The increase in survival was most marked among patients found in a shockable rhythm and those hospitalized with ROSC. There were improvements in all four links in the chain of survival, which might explain the improved outcome.

  • Cardiac arrest in COVID-19 : characteristics and outcomes of in- and out-of-hospital cardiac arrest. A report from the Swedish Registry for Cardiopulmonary Resuscitation.
  • 2021
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 42:11, s. 1094-1106

    • AIM: To study the characteristics and outcome among cardiac arrest cases with COVID-19 and differences between the pre-pandemic and the pandemic period in out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA).METHOD AND RESULTS: We included all patients reported to the Swedish Registry for Cardiopulmonary Resuscitation from 1 January to 20 July 2020. We defined 16 March 2020 as the start of the pandemic. We assessed overall and 30-day mortality using Cox regression and logistic regression, respectively. We studied 1946 cases of OHCA and 1080 cases of IHCA during the entire period. During the pandemic, 88 (10.0%) of OHCAs and 72 (16.1%) of IHCAs had ongoing COVID-19. With regards to OHCA during the pandemic, the odds ratio for 30-day mortality in COVID-19-positive cases, compared with COVID-19-negative cases, was 3.40 [95% confidence interval (CI) 1.31-11.64]; the corresponding hazard ratio was 1.45 (95% CI 1.13-1.85). Adjusted 30-day survival was 4.7% for patients with COVID-19, 9.8% for patients without COVID-19, and 7.6% in the pre-pandemic period. With regards to IHCA during the pandemic, the odds ratio for COVID-19-positive cases, compared with COVID-19-negative cases, was 2.27 (95% CI 1.27-4.24); the corresponding hazard ratio was 1.48 (95% CI 1.09-2.01). Adjusted 30-day survival was 23.1% in COVID-19-positive cases, 39.5% in patients without COVID-19, and 36.4% in the pre-pandemic period.CONCLUSION: During the pandemic phase, COVID-19 was involved in at least 10% of all OHCAs and 16% of IHCAs, and, among COVID-19 cases, 30-day mortality was increased 3.4-fold in OHCA and 2.3-fold in IHCA.

  • Cardiac troponin-I and risk of heart failure : a community-based cohort study
  • 2009
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 30:7, s. 773-781
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: We examined if circulating levels of cardiac troponin-I (cTnI) predict subsequent heart failure in the community. METHODS AND RESULTS: Using Cox proportional hazards models, we examined the risk of a first hospitalization for heart failure during a maximum of 11.4 years in a community-based sample of 1089 70-year-old men without heart failure, valvular disease, or electrocardiographic left ventricular hypertrophy. Adjusting for smoking, systolic blood pressure, antihypertensive medication use, diabetes, body mass index, serum cholesterol, and myocardial infarction before baseline or during follow-up, 0.01 microg/L higher cTnI conferred a hazard ratio (HR) of 1.26 (95% confidence interval 1.15-1.38) for subsequent heart failure. Persons with cTnI > or =0.03 microg/L had an HR of 5.25 (2.00-13.77) compared with persons with cTnI <0.01 microg/L. Adjusting additionally for serum NTproBNP attenuated the estimates somewhat [HR 1.22 (1.11-1.34) per 0.01 microg/L of cTnI]. Excluding persons with myocardial infarction before baseline and censoring at time of myocardial infarction during follow-up, 0.01 microg/L higher cTnI was associated with a multivariable-adjusted HR of 1.31 (1.16-1.47) for heart failure. CONCLUSION: In a community-based sample, a direct measure of cardiomyocyte damage, cTnI, indicated a substantially increased risk of heart failure, accounting for other risk factors. Studies investigating the clinical utility of measuring cTnI in asymptomatic individuals are warranted.

  • The association between serum cathepsin L and mortality in older adults
  • 2016
  • Ingår i: Atherosclerosis. - : Elsevier BV. - 0021-9150 .- 1879-1484. ; 37, s. 1283-1283
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND AND AIMS: Research suggests that the protease cathepsin L is causally involved in atherosclerosis. However, data on cathepsin L as a risk marker are lacking. Therefore, we investigated associations between circulating cathepsin L and cardiovascular mortality.METHODS: Two independent community-based cohorts were used: Uppsala Longitudinal Study of Adult Men (ULSAM); n = 776; mean age 77 years; baseline 1997-2001; 185 cardiovascular deaths during 9.7 years follow-up, and Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS); n = 993; 50% women; mean age 70 years; baseline 2001-2004; 42 cardiovascular deaths during 10.0 years follow-up.RESULTS: Higher serum cathepsin L was associated with an increased risk for cardiovascular mortality in age- and sex-adjusted models in both cohorts (ULSAM: hazard ratio (HR) for 1-standard deviation (SD) increase, 1.17 [95% CI, 1.01-1.34], p = 0.032 PIVUS: HR 1.35 [95% CI, 1.07-1.72], p = 0.013). When merging the cohorts, these associations were independent of inflammatory markers and cardiovascular risk factors, but non-significant adjusting for kidney function. Individuals with a combination of elevated cathepsin L and increased inflammation, kidney dysfunction, or prevalent cardiovascular disease had a markedly increased risk, while no increased risk was associated with elevated cathepsin L, in the absence of these disease states.CONCLUSIONS: An association between higher serum cathepsin L and increased risk of cardiovascular mortality was found in two independent cohorts. Impaired kidney function appears to be an important moderator or mediator of these associations. Further studies are needed to delineate the underlying mechanisms and to evaluate whether the measurement of cathepsin L might have clinical utility.
