Smokeless Tobacco (Snus) and Outcome of Myocardial Infarction: a SWEDEHEART Study
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- BackgroundBased on effects of nicotine and snus (a smokeless tobacco) on hemodynamics, pro-arrhythmia and remodelling, in combination with indications of increased risk for fatal myocardial infarction (MI) in snus users; we hypothesised that the outcome of an MI may be worse in snus users.MethodsData was extracted from the SWEDEHEART registry for all patients who underwent coronary angiography in Sweden due to MI between December 2009 and December 2014. In snus users (n=4,950) relative to snus non-users (n=55,412), we compared risks of a large MI (defined as hs-cTnT of > 10,000 ng/L, cTnT > 10 μg/L or cTnI > 10 μg/L) and death in the acute (in-hospital) setting, and death+HF (a combined endpoint of all-cause death or hospitalization for heart failure) and all-cause death at short- (<28 days) and long-term follow-up. Relations of snus use to outcomes were also analysed in pre-specified subgroups of never, previous and current smokers.ResultsA large MI was diagnosed in 10,975 patients. During long-term follow-up (median 1.9 years), 7,758 either died (n=6,044) or were hospitalized due to heart failure (n=1,714). In models adjusting for age, gender, smoking, previous MI and occupational classification (employed, unemployed/sick leave and retired), snus use was not associated with risk of large MI (odds ratio 1.01; 95% confidence interval (CI) 0.93-1.09) or death+HF (long-term Cox proportional hazard ratio (HR) 0.99; 95% CI 0.90-1.10). Nonetheless, among never-smokers snus use was associated with an increased risk for death+HF (long-term HR 1.26, 95% CI 1.03-1.55), driven by a higher mortality risk (long-term HR for death of any cause 1.29, 95% CI 1.02-1.64).ConclusionsIn this study, snus use was unrelated to acute, short-term or long-term adverse outcomes after an MI. Among never-smokers, snus use was associated with an increased risk of post-MI death.

Tidskriftsartikel (refereegranskat)abstract
- Background: We aimed to optimize prediction of long-term all-cause mortality of intensive care unit (ICU) patients, using quantitative register-based comorbidity information assessed from hospital discharge diagnoses prior to intensive care treatment.Material and methods: Adult ICU admissions during 2006 to 2012 in the Swedish intensive care register were followed for at least 4 years. The performance of quantitative comorbidity measures based on the 5-year history of number of hospital admissions, length of stay, and time since latest admission in 36 comorbidity categories was compared in time-to-event analyses with the Charlson comorbidity index (CCI) and the Simplified Acute Physiology Score (SAPS3).Results: During a 7-year period, there were 230,056 ICU admissions and 62,225 deaths among 188,965 unique individuals. The time interval from the most recent hospital stays and total length of stay within each comorbidity category optimized mortality prediction and provided clear separation of risk categories also within strata of age and CCI, with hazard ratios (HRs) comparing lowest to highest quartile ranging from 1.17 (95% CI: 0.52-2.64) to 6.41 (95% CI: 5.19-7.92). Risk separation was also observed within SAPS deciles with HR ranging from 1.07 (95% CI: 0.83-1.38) to 3.58 (95% CI: 2.12-6.03).Conclusion: Baseline comorbidity measures that included the time interval from the most recent hospital stay in 36 different comorbidity categories substantially improved long-term mortality prediction after ICU admission compared to the Charlson index and the SAPS score. Trial registration ClinicalTrials.gov ID NCT04109001, date of registration 2019-09-26 retrospectively.

- Aims Optimal antithrombotic therapy after percutaneous coronary intervention (PCI) in patients with myocardial infarction (MI) and atrial fibrillation is uncertain. In this study, we compared antithrombotic regimes with regard to a composite cardiovascular outcome of all-cause mortality, MI or ischaemic stroke, and major bleeds. Methods and results Patients between October 2005 and December 2012 were identified in Swedish registries, n = 7116. Landmark 0-90 and 91-365 days of outcome were evaluated with Cox-regressions, with dual antiplatelet therapy as reference. At discharge, 16.2% received triple therapy (aspirin, clopidogrel, and warfarin), 1.9% aspirin plus warfarin, 7.3% clopidogrel plus warfarin, and 60.8% dual antiplatelets. For cardiovascular outcome, adjusted hazard ratio with 95% confidence interval (HR) for triple therapy was 0.86 (0.70-1.07) for 0-90 days and 0.78 (0.58-1.05) for 91-365 days. A HR of 2.16 (1.48-3.13) and 1.61 (0.98-2.66) during 0-90 and 91-365 days, respectively, was observed for major bleeds. For aspirin plus warfarin, HR 0.82 (0.54-1.26) and 0.62 (0.48-0.79) was observed for cardiovascular outcome and 1.30 (0.60-2.85) and 1.01 (0.63-1.62) for major bleeds during 0-90 and 91-365 days, respectively. For clopidogrel plus warfarin, HR of 0.90 (0.68-1.19) and 0.68 (0.49-0.95) was observed for cardiovascular outcome and 1.28 (0.71-2.32) and 1.08 (0.57-2.04) for major bleeds during 0-90 and 91-365 days, respectively. Conclusion Compared to dual antiplatelets, aspirin or clopidogrel plus warfarin therapy was associated with similar 0-90 days and lower 91-365 days of risk of the cardiovascular outcome, without higher risk of major bleeds. Triple therapy was associated with non-significant lower risk of cardiovascular outcome and higher risk of major bleeds.

Impact of prehospital trauma life support (PHTLS) training of ambulance caregivers on the outcome of traffic injury victims – a nation-wide study.
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Prehospital trauma life support (PHTLS) is a widely implemented educational program for prehospital trauma care. Evidence for improved patient outcome is, however, limited. The primary aim of this nation-wide study was to investigate the association between regional implementation of PHTLS training and mortality after traffic injuries.Methods: We extracted from the Swedish National Patient Registry and the Cause of Death Registry information on victims of motor vehicle traffic injuries in Sweden from 2001 to 2004 (n=28 041). During this time period, PHTLS training was implemented at a varying pace in different regions. We used a Bayesian approach with Markov chain Monte Carlo to estimate odds ratios (OR) for prehospital and 30-day mortality. We entered region and hospital into hierarchical models and controlled for the calendar year for each injury. We analyzed the time to death and time to return to work using Cox’s proportional hazards frailty models.Results: A total of 1395 individuals died before being admitted to hospital. After multivariable adjustment, the OR for prehospital mortality with PHTLS-trained prehospital staff was 1.11 (95% credibility interval, 0.88 to 1.38). For 30-day mortality (365 deaths), the adjusted OR was 0.80 (95% credibility interval, 0.53 to 1.17). There was no association between PHTLS training and time to death (hazard ratio 0.99; 95% confidence interval, 0.85 to 1.14) or time to return to work (hazard ratio 0.98, 95% confidence interval, 0.92 to 1.05).Conclusion: The implementation of PHTLS training did not appear to reduce mortality or disability after motor vehicle traffic injuries. .

- BACKGROUND:There is limited evidence that the widely implemented Prehospital Trauma Life Support (PHTLS) educational program improves patient outcomes. The primary aim of this national study in Sweden was to investigate the association between regional implementation of PHTLS training and mortality after traffic injuries.STUDY DESIGN:We extracted information from the Swedish National Patient Registry and the Cause of Death Registry on victims of motor-vehicle traffic injuries in Sweden from 2001 to 2004 (N = 28,041). During this time period, PHTLS training was implemented at a varying pace in different regions. To control for other influences on patient outcomes related to regional and hospital-level effects, such as variations in performance of trauma care systems, we used Bayesian hierarchical regression models to estimate odds ratios for prehospital mortality and 30-day mortality after hospital admission. We also controlled for the calendar year for each injury to account for period effects. We analyzed the time to death after hospital admission and time to return to work using Cox's proportional hazards frailty models.RESULTS:After multivariable adjustment, the odds ratio for prehospital mortality with PHTLS-trained prehospital staff was 1.54 (95% credibility interval, 1.07-2.13). For 30-day mortality among those surviving to hospital admission, the odds ratio was 0.85 (95% credibility interval, 0.45-1.48). There was no association between PHTLS training and time to death (hazard ratio = 0.99; 95% CI, 0.85-1.14) or time to return to work (hazard ratio = 0.98; 95% CI, 0.92-1.05).CONCLUSIONS:In this observational study, the implementation of PHTLS training did not appear to be associated with reduced mortality or ability to return to work after motor-vehicle traffic injuries.

- Aims. - Elevated body mass index (BMI) is associated with an increased risk of type 2 diabetes and cardiovascular disease (CVD). This study explored the association between BMI changes in the first 18 months of newly diagnosed type 2 diabetes and the risk of long-term CVD mortality. less thanbrgreater than less thanbrgreater thanMethods. - A total of 8486 patients with newly diagnosed type 2 diabetes and no previous history of CVD or cancer were identified from 84 primary-care centres in Sweden. During the first year after diagnosis, patients were grouped according to BMI change: Increase, or andgt;= +1 BMI unit; unchanged, or between +1 and-1 BMI unit; and decrease, or andlt;=-1 BMI unit. Associations between BMI change and CVD mortality, defined as death from stroke, myocardial infarction or sudden death, were estimated using adjusted Cox proportional hazards models (NCT 01121315). less thanbrgreater than less thanbrgreater thanResults. - Baseline mean age was 60.0 years and mean BMI was 30.2 kg/m(2). Patients were followed for up to 9 years (median: 4.6 years). During the first 18 months, 53.4% had no change in their BMI, while 32.2% decreased and 14.4% increased. Compared with patients with unchanged BMI, those with an increased BMI had higher risks of CVD mortality (hazard ratio: 1.63, 95% CI: 1.11-2.39) and all-cause mortality (1.33, 1.01-1.76). BMI decreases had no association with these risks compared with unchanged BMI: 1.06 (0.76-1.48) and 1.06 (0.85-1.33), respectively. less thanbrgreater than less thanbrgreater thanConclusion. - Increased BMI within the first 18 months of type 2 diabetes diagnosis was associated with an increased long-term risk of CVD mortality. However, BMI decrease did not lower the long-term risk of mortality.
