- 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.

- 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.

- BACKGROUND: Classification agreement between instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) is approximately 80% in stable patients. It was recently shown that FFR guidance, as compared to iFR guidance, was associated with a higher risk of subsequent revascularization among patients with non- ST-segment elevation myocardial infarction. The classification agreement, and the impact of time interval, between iFR and FFR in the assessment of non-culprit lesions after recent ST-segment elevation myocardial infarction (STEMI) has not been described.METHODS: The iSTEMI study assessed agreement between iFR across non-culprit stenoses at the index procedure in patients with STEMI versus iFR and FFR at a follow-up angiography. The interval between STEMI and follow-up evaluation was at the discretion of the treating physicians. In this substudy, classification agreement between follow-up iFR and follow-up FFR was evaluated within groups defined according to follow-up time point after STEMI, i.e., <5days, 5-15days, and16 days. iFR<0.90 and FFR0.80 were considered hemodynamically significant.RESULTS: Among 120 patients with 157 non-culprit stenoses, follow-up iFR and FFR was available in 112 patients with 146 non-culprit stenoses. Median follow-up interval was 16 days (IQR 5-32 days). The overall classification agreement was 84%. With follow-up<5days after STEMI, there was classification agreement between iFR and FFR was in 27 of 35 (77%) non-culprit stenoses. With follow-up 5-15 after STEMI, there was classification agreement in 33 of 38 (86%) non-culprit stenoses. With follow-up 16 days after STEMI, there was classification agreement in 63 of 73 (86%) non-culprit stenoses. The observed differences in these proportions over time after STEMI were not statistically significant (<5versus5days, p¼0.19).CONCLUSION: Overall, classification agreement between iFR and FFR in the assessment of non-culprit lesions after STEMI was comparable to that observed in stable patients. Time interval between STEMI and follow-up evaluation may impact agreement between follow-up iFR and follow-up FFR, although the observed differences were not statistically significant.

- OBJECTIVE: To evaluate agreement between instantaneous wave free ratio (iFR) and fractional flow reserve (FFR) for the functional assessment of nonculprit coronary stenoses at staged follow-up after ST-segment elevation myocardial infarction (STEMI).RESULTS: We measured iFR and FFR at staged follow-up in 112 STEMI patients with 146 nonculprit stenoses. Median interval between STEMI and follow-up was 16 (interquartile range 5-32) days. Agreement between iFR and FFR was 77% < 5 days after STEMI and 86% after ≥ 5 days (p = 0.19). Among cases with disagreement, the proportion of cases with hemodynamically significant iFR and non-significant FFR were different when assessed < 5 days (5 in 8, 63%) versus ≥ 5 days (3 in 15, 20%) after STEMI (p = 0.04). Overall classification agreement between iFR and FFR was comparable to that observed in stable patients. Time interval between STEMI and follow-up evaluation may impact agreement between iFR and FFR.

- Objectives: The instantaneous wave-free ratio cutoff value of <0.90 for hemodynamic significance of coronary stenoses has been validated in stable patients. We examined different cutoff values in the evaluation of nonculprit stenoses in patients with ST-segment elevation myocardial infarction.Methods: We measured instantaneous wave-free ratio across nonculprit stenoses in the acute setting and at follow-up in 120 patients with ST-segment elevation myocardial infarction and 157 nonculprit stenoses, of which, 113 patients with 147 nonculprit stenoses completed follow-up.Results: The prevalence of nonculprit stenosis hemodynamic significance was 52% in the acute setting and 41% at follow-up. With follow-up, instantaneous wave-free ratio as reference, acute instantaneous wave-free ratio >0.90 had a negative predictive value of 89%. Acute instantaneous wave-free ratio <0.90 had a positive predictive value of 68%. Acute instantaneous wave-free ratio >0.93 had a negative predictive value of 100%. Acute instantaneous wave-free ratio <0.86 and <0.83 had positive predictive values of 71 and 77%. Using acute instantaneous wave-free ratio <0.90 as cutoff for hemodynamic significance yielded the highest degree of classification agreement between acute and follow-up instantaneous wave-free ratio.Conclusions: In patients with ST-segment elevation myocardial infarction, acute instantaneous wave-free ratio with the cutoff values <0.90 for hemodynamic significance appears optimal in the evaluation of nonculprit stenoses and has a high negative predictive value and a moderate positive predictive value.

- OBJECTIVES: The aim of this study was to examine the level of agreement between acute instantaneous wave-free ratio (iFR) measured across nonculprit stenoses in patients with ST-segment elevation myocardial infarction (STEMI) and iFR measured at a staged follow-up procedure.BACKGROUND: Acute full revascularization of nonculprit stenoses in STEMI is debated and currently guided by angiography. Acute functional assessment of nonculprit stenoses may be considered.METHODS: Immediately after successful primary culprit intervention for STEMI, nonculprit coronary stenoses were evaluated with iFR and left untreated. Follow-up evaluation with iFR was performed at a later stage. iFR <0.90 was considered hemodynamically significant.RESULTS: One hundred twenty patients with 157 nonculprit lesions were included. Median acute iFR was 0.89 (interquartile range: 0.82 to 0.94; n = 156), and median follow-up iFR was 0.91 (interquartile range [IQR]: 0.86 to 0.96; n = 147). Classification agreement was 78% between acute and follow-up iFR. The negative predictive value of acute iFR was 89%. Median time from acute to follow-up evaluation was 16 days (IQR: 5 to 32 days). With follow-up within 5 days after STEMI, no difference was observed between acute and follow-up iFR, and classification agreement was 89%. With follow-up ≥16 days after STEMI, acute iFR was lower than follow-up iFR, and classification agreement was 70%.CONCLUSIONS: Acute iFR evaluation appeared valid for ruling out significant nonculprit stenoses in patients with STEMI undergoing primary percutaneous coronary intervention. The time interval from acute to follow-up iFR influenced classification agreement, suggesting that inherent physiological disarrangements during STEMI may contribute to classification disagreement.

- The aim of this study was to conduct a nationwide all comer description of incidence, contemporary management and outcome in Swedish spontaneous coronary artery dissection (SCAD) patients. The incidence of SCAD as well as the management and outcome of these patients is not well described.A nationwide observational study.All patients with SCAD registered in the Swedish Coronary Angiography and Angioplasty Register from 2015 to 2017 were included. The index angiographies of patients with registered SCAD were re-evaluated at each centre to confirm the diagnosis. Patients with non-SCAD myocardial infarction (MI) (n=32 601) were used for comparison.Outcomes included all-cause mortality, reinfarction or acute coronary reangiography.This study found 147 SCAD patients, rendering an incidence of 0.74 per 100 000 per year and a prevalence of 0.43% of all MIs. The average age was 52.9 years, 75.5% were women and 47.6% presented with ST-segment elevation MI. Median follow-up time for major adverse cardiac event was 17.3 months. Percutaneous coronary intervention was attempted in 40.1% of SCAD patients and 30.6% received stent. The use of antithrombotic agents was similar between the groups and there was no difference regarding outcomes, 10.9% vs 13.4%, p=0.75. Mortality was lower in SCAD patients, 2.7% vs 8.0%, p=0.03, whereas SCAD patients more often underwent acute reangiography, 9.5% vs 4.6%, p<0.01.In this nationwide, all comer Swedish study, the overall incidence of SCAD was low, including 25% men which is more and in contrast to previous studies. Compared with non-SCAD MI, SCAD patients were younger, with lower cardiovascular risk burden, yet suffered substantial mortality and morbidity and more frequently underwent acute coronary reangiography.

- BACKGROUND: Most trials showing benefit of beta-blocker treatment after myocardial infarction (MI) included patients with large MIs and are from an era before modern biomarker-based MI diagnosis and reperfusion treatment. The aim of the Randomized Evaluation of Decreased Usage of betabloCkErs after Acute Myocardial Infarction (REDUCE-AMI) trial is to determine whether long-term oral beta-blockade in patients with an acute MI and preserved left ventricular ejection fraction (EF) reduces the composite endpoint of death of any cause or recurrent MI.METHODS: It is a registry-based, randomized, parallel, open-label, multicenter trial performed at 38 centers in Sweden, one center in Estonia and six centers in New Zealand. About 5000 patients with an acute MI who have undergone coronary angiography and with EF ≥ 50% will be randomized to long-term treatment with beta-blockade or not. The primary endpoint is the composite endpoint of death of any cause or new non-fatal MI. There are several secondary endpoints, including all-cause death, cardiovascular death, new MI, readmission because of heart failure and atrial fibrillation, symptoms, functional status, health related quality of life after 6-10 weeks and after 1 year of treatment. Safety endpoints are bradycardia, AV-block II-III, hypotension, syncope or need for pacemaker, asthma or chronic obstructive pulmonary disease and stroke.CONCLUSION: The results from REDUCE-AMI will add important evidence regarding the effect of beta-blockers in patients with MI and preserved EF and may change guidelines and clinical practice.
