Redfors B, Jha S, Thorleifsson S, et al. - An observational cohort study based on the data from the SCAAR (Swedish Coronary Angiography and Angioplasty Registry) was performed to describe the relative short‐term mortality risk of Takotsubo syndrome (TS; a potentially life‐threatening acute cardiac syndrome with a clinical presentation similar to myocardial infarction), ST‐segment–elevation myocardial infarction (STEMI), and non‐STEMI (NSTEMI).

• Retrieval of data of patients (n = 117,720) who underwent coronary angiography in Sweden attributed to TS (N=2898 [2.5%]), STEMI (N=48 493 [41.2%]), or NSTEMI (N = 66,329 [56.3%]) was performed.

• Relative to NSTEMI, a higher 30‐day mortality rate was recorded in correlation with TS.

• However, relative to STEMI, there was a lower 30‐day mortality rate despite a similar risk of acute heart failure in TS and STEMI.

• Smoking was identified to have an independent predictive value for mortality among patients with TS.
