- Background: Takotsubo syndrome (TS) is a potentially life-threatening acute cardiac syndrome with a clinical presentation very similar to myocardial infarction (MI) and for which the natural history, management and outcome remain incompletely understood.Purpose: The aims of this study were to assess the relative short- and long-term mortality risk of TS , ST-elevation MI (STEMI) and non STEMI (NSTEMI) and to identify predictors of in-hospital complications and poor prognosis in patients with TS.Methods: Using the nationwide Swedish Angiography and Angioplasty Registry (SCAAR) we identified almost all (n=117,720) patients who underwent coronary angiography due to TS (N=2,898 [2.5%]), STEMI (N=48,493 [41.2%]) or NSTEMI (N=66,329 [56.3%]) in Sweden between January 2009 and February 2018.Results: Patients with TS were more often women as compared with patients with STEMI or NSTEMI. TS was associated with unadjusted and adjusted 30-day mortality risks lower than STEMI (adjusted hazard ratio [adjHR] 0.60, 95% confidence interval [CI]0.48-0.76, p<0.001), but higher than NSTEMI (adjHR 2.70, 95% CI 2.14-3.41, p<0.001). Compared to STEMI, TS was associated with similar risk of acute heart failure (adjHR 1.26, 95% CI 0.91–1.76, p=0.16) but lower risk of cardio-genic shock (adjHR 0.55, 95% CI 0.34–0.89, p=0.02). The relative 30-day mortality risk for TS versus STEMI and NSTEMI was higher for smokers than non-smokers (adjusted pinteractionSTEMI=0.01 and pinteractionNSTEMI=0.01).Conclusion: Thirty-day mortality in TS was higher than in NSTEMI but lower than STEMI, despite a similar risk of acute heart failure in TS and STEMI. Among patients with TS, smoking was an independent predictor of mortality

- BACKGROUND: The Second Primary Angioplasty in Myocardial Infarction (PAMI-II) risk score is recommended by guidelines to identify low-risk patients with ST-elevation myocardial infarction (STEMI) for an early discharge strategy. AIMS: We aimed to assess the safety of early discharge (≤2 days) for low-risk STEMI patients treated with primary percutaneous coronary intervention (PCI). METHODS: Using nationwide data from the SWEDEHEART registry, we identified patients with STEMI treated with primary PCI during the period 2009-2017, of whom 8,092 (26.4%) were identified as low risk with the PAMI-II score. Low-risk patients were stratified according to their length of hospital stay (≤2 days vs >2 days). The primary endpoint was major adverse cardiovascular events (MACE, including death, reinfarction treated with PCI, stroke or heart failure hospitalisation) at one year, assessed using a Cox proportional hazards model with propensity score as well as an inverse probability weighting propensity score of average treatment effect to adjust for confounders. RESULTS: A total of 1,449 (17.9%) patients were discharged ≤2 days from admission. After adjustment, the one-year MACE rate was not higher for patients discharged at >2 days from admission than for patients discharged ≤2 days (4.3% vs 3.2%; adjusted HR 1.31, 95% confidence interval [CI]: 0.92-1.87, p=0.14), and no difference was observed regarding any of the individual components of the main outcome. Results were consistent across all subgroups with no difference in MACE between early and late discharge patients. CONCLUSIONS: Nationwide observational data suggest that early discharge of low-risk patients with STEMI treated with PCI is not associated with an increase in one-year MACE.
