Clinical Trial Summary

A retrospective cohort study will be conducted on patients who were hospitalized at the University Hospital Basel (USB), University Hospital Bern (Inselspital), University Hospital Geneva (HUG) and the University Hospital Zurich (USZ) with the diagnosis of AMI and/or AHF. Baseline data will be collected in the hospital during treatment will be complemented by a short outcome evaluation.

Description:

The SWISSHEART Failure (SHF) Registry collects retrospectively Swiss-wide standardized clinical, laboratory, raw data electrocardiograms (ECG) and transthoracic echocardiographies (TTE) of a large number of patients hospitalized for Acute Heart Failure (AHF) or for Acute Myocardial Infarction (AMI), this latter group being at risk of developing heart failure as a consequence of the AMI episode. Using state-of-the-art statistics and machine learning (ML)-based analyses, This project aims to improve prediction and prevention of heart failure (HF) in AMI patients and understand progression or regression of HF in AHF patients.
