Study summary

This retrospective cohort study is to identify triggers of heart failure (HF) development and drivers of HF progression as well as the underlying cardiac disease (phenotype) to identify patients at risk and predict the clinical course of the disease. Data of patients who were hospitalized during the years 2010-2023 with acute coronary syndrome (ACS) and/ or with acute heart failure (AHF) will be collected and analyzed. In a subgroup cohort efficacy and safety of digoxin in patients with acute heart failure triggered by tachyarrhythmia will be evaluated.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
