- AIMS: To describe the time trends of in-hospital and out-of-hospital bleeding parallel to the development of new treatments and ischaemic outcomes over the last 20 years in a nationwide myocardial infarction (MI) population.METHODS AND RESULTS: Patients with acute MI (n = 371 431) enrolled in the SWEDEHEART registry from 1995 until May 2018 were selected and evaluated for in-hospital bleeding and out-of-hospital bleeding events at 1 year. In-hospital bleeding increased from 0.5% to a peak at 2% 2005/2006 and thereafter slightly decreased to a new plateau around 1.3% by the end of the study period. Out-of-hospital bleeding increased in a stepwise fashion from 2.5% to 3.5 % in the middle of the study period and to 4.8% at the end of the study period. The increase in both in-hospital and out-of-hospital bleeding was parallel to increasing use of invasive strategy and adjunctive antithrombotic treatment, dual antiplatelet therapy (DAPT), and potent DAPT, while the decrease in in-hospital bleeding from 2007 to 2010 was parallel to implementation of bleeding avoidance strategies. In-hospital re-infarction decreased from 2.8% to 0.6% and out-of-hospital MI decreased from 12.6% to 7.1%. The composite out-of-hospital MI, cardiovascular death, and stroke decreased in a similar fashion from 18.4% to 9.1%.CONCLUSION: During the last 20 years, the introduction of invasive and more intense antithrombotic treatment has been associated with an increase in bleeding events but concomitant there has been a substantial greater reduction of ischaemic events including improved survival.

- BACKGROUND: The comparative efficacy and safety of ticagrelor versus clopidogrel in older patients with myocardial infarction (MI) has received limited study. METHODS: We performed an observational analysis of all patients ≥80 years (n=14 005) who were discharged alive with aspirin combined with either clopidogrel (60.2%) or ticagrelor (39.8%) after a MI between 2010 and 2017 registered in the national registry SWEDEHEART (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies). Inverse probability treatment weighting was used in Cox regression models to adjust for differences in demographics, in-hospital therapies, and medications. The primary ischemic outcome (death, MI, or stroke), and bleeding were obtained from national registries at 1 year. A sensitivity analysis in <80-year-old patients was performed. RESULTS: In patients ≥80 years, the incidence of the primary ischemic outcome (hazard ratio [HR], 0.97 [95% CI, 0.88-1.06]) was similar for ticagrelor- and clopidogrel-treated patients. Ticagrelor was associated with a 17% and 48% higher risk of death (HR, 1.17 [95% CI, 1.03-1.32]) and bleeding (HR, 1.48 [95% CI, 1.25-1.76]), but a lower risk of MI (HR, 0.80 [95% CI, 0.70-0.92]) and stroke (HR, 0.72 [95% CI, 0.56-0.93]). In <80-year-old patients, the incidence of the primary ischemic outcome was 17% (HR, 0.83 [95% CI, 0.77-0.89]) lower with ticagrelor. Ticagrelor was associated with 15% (HR, 0.85 [95% CI, 0.76-0.96]) lower risk of death, 32% higher risk of bleeding (HR, 1.32 [95% CI, 1.18-1.47]), but lower risk of MI (HR, 0.82 [95% CI, 0.75-0.91]) and stroke (HR, 0.82 [95% CI, 0.69-0.98]). CONCLUSIONS: Ticagrelor use among elderly patients with MI was associated with higher risk of bleeding and death compared with clopidogrel. A randomized study of ticagrelor versus clopidogrel in the elderly is needed.

- Aims Impact of changes of treatments on outcomes in ST-elevation myocardial infarction (STEMI) patients in real-life health care has not been documented. Methods and results All STEMI cases (n=105.674) registered in the nation-wide SWEDEHEART registry between 1995 and 2014 were included and followed for fatal and non-fatal outcomes for up to 20 years. Most changes in treatment and outcomes occurred from 1994 to 2008. Evidence-based treatments increased: reperfusion from 66.2 to 81.7%; primary percutaneous coronary intervention: 4.5 to 78.0%; dual antiplatelet therapy from 0 to 89.6%; statin: 14.1 to 93.6%; beta-blocker: 78.2 to 91.0%, and angiotensin-converting-enzyme/angiotensin-2-receptor inhibitors: 40.8 to 85.2% (P-value for-trend<0.001 for all). One-year mortality decreased from 22.1 to 14.1%. Standardized incidence ratio compared with the general population decreased from 5.54 to 3.74 (P<0.001). Cardiovascular (CV) death decreased from 20.1 to 11.1%, myocardial infarction (MI) from 11.5 to 5.8%; stroke from 2.9 to 2.1%; heart failure from 7.1 to 6.2%. After standardization for differences in demography and baseline characteristics, the change of 1-year CV-death or MI corresponded to a linear trend of 0.915 (95% confidence interval: 0.906-0.923) per 2-year period which no longer was significant, 0.997 (0.984-1.009), after adjustment for changes in treatment. The changes in treatment and outcomes were most pronounced from 1994 to 2008. Conclusion Gradual implementation of new and established evidence-based treatments in STEMI patients during the last 20 years has been associated with prolonged survival and lower risk of recurrent ischaemic events, although a plateauing is seen since around 2008.

- Aims We assessed the changes in short- and long-term outcomes and their relation to implementation of new evidence- based treatments in all patients with non-ST-elevation myocardial infarction (NSTEMI) in Sweden over 20 years. Methods and results Cases with NSTEMI (n = 205 693) between 1995 and 2014 were included from the nationwide Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) registry. During 20 years in-hospital invasive procedures increased from 1.9% to 73.2%, percutaneous coronary intervention or coronary artery bypass grafting 6.5% to 58.1%, dual antiplatelet medication 0% to 72.7%, statins 13.3% to 85.6%, and angiotensin-converting enzyme inhibitors/angiotensin II receptor blocker 36.8% to 75.5%. The standardized 1-year mortality ratio compared with a control population decreased from 5.53 [95% confidence interval (CI) 5.30-5.75] to 3.03 (95% CI 2.89-3.19). If patients admitted the first 2 years were modelled to receive the same invasive treatments as the last 2 years the expected mortality/ myocardial infarction (MI) rate would be reduced from 33.0% to 25.0%. After adjusting for differences in baseline characteristics, the change of 1-year cardiovascular death/MI corresponded to a linearly decreasing odds ratio trend of 0.930 (95% CI 0.926-0.935) per 2-year period. This trend was substantially attenuated [0.970 (95% CI 0.964-0.975)] after adjusting for changes in coronary interventions, and almost eliminated [0.988 (95% CI 0.982-0.994)] after also adjusting for changes in discharge medications. Conclusion In NSTEMI patients during the last 20 years, there has been a substantial improvement in long-term survival and re- duction in the risk of new cardiovascular events. These improvements seem mainly explained by the gradual uptake and widespread use of in-hospital coronary interventions and evidence-based long-term medications.
