Risk of death and thrombosis in patients admitted to the emergency department with supraventricular tachycardias

Heart RhythmPublished Retrospective cohort study

Authors' conclusion

The increased risk of adverse events in patients with SVT appears to be most pronounced in the short term and partly associated with the increased likelihood of incident AF.

Study context

Population
ED patients with supraventricular tachycardia (SVT), atrial fibrillation (AF), atrial flutter or controls, not taking OAC, identified by ICD codes in TriNetX
Participants
23,524 / 5,413 / 157,715 / 150,807
Exposure
SVT vs controls, atrial flutter and AF
  • SVTn = 23,524
  • Atrial fluttern = 5,413
  • AFn = 157,715
  • Control (CTRL)n = 150,807
Outcome
Composite of:
  • All-cause death
  • Thromboembolism
Follow-up
1 year
Methodological detailspropensity-score matched, TriNetX
  • Propensity-score matched
  • TriNetX

Main finding

As reported in the abstract

Hazard ratio (95% CI)
SVTvs CTRL
2.89(2.65–3.17)
SVTvs Atrial flutter
0.87(0.79–0.97)
SVTvs AF
0.69(0.65–0.73)

Observational data: associations, not effects.

Further findings

Composite outcome in SVT by time, sex, age, multimorbidity (subgroups) · first 30 days

Risk in SVT more pronounced during first 30 days in males, age ≥65 years, or multimorbidity

Incident AF

Increased risk of incident AF in SVT vs CTRL
