Population studied

• Short description of the study population:
  The source population will include all patients present in the database from January 1st, 2015 (first EU approval of sacubitril/valsartan) to 31st December 2023 (or the last available date).

Study design details

• Study design:
  The incidence of the event of interest will be assessed using a population-level descriptive epidemiology design.
• Main study objective:
  1. To calculate the incidence rate of myoclonus in a newly diagnosed heart failure population and the general population, stratified by age groups and sex. ; 2. To calculate the incidence rate of myoclonus in a heart failure population following first initiation of treatment cohorts: sacubitril/valsartan, angiotensin-converting enzyme inhibitors (ACEi), and angiotensin receptor blockers (ARBs) (index date being the start of the treatment).
