Fast discharge after heart attack treatment
Official title: Fast Discharge After Acute Myocardial Infarction Discharge MI - A Randomized Multicenter Non Inferiority Trial
Run by Medical University Innsbruck · NCT06744322 · Data updated 2026-11-12
This study is testing if patients who have a heart attack can safely leave the hospital just 24 hours after treatment instead of the usual 72 hours.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who have experienced an uncomplicated acute myocardial infarction and have undergone successful invasive management.
✕Probably not a fit
Patients with complicated myocardial infarctions, such as those who experienced cardiac arrest or malignant arrhythmias, may not benefit from this study.

What this trial studies
This trial evaluates whether a fast discharge strategy, allowing patients to leave the hospital 24 hours after treatment for acute myocardial infarction, is as safe as the standard discharge time of 72 hours. It is a randomized, multicenter trial that focuses on patients who have undergone invasive management for their heart condition. The primary goal is to assess the risk of major adverse cardiovascular events within 12 months following discharge. By comparing these two discharge strategies, the study aims to determine if quicker discharge can be safely implemented without increasing risks.
Why it matters
Potential benefit: If successful, this approach could lead to shorter hospital stays for heart attack patients without compromising their safety.
How similar studies have gone: Other studies have explored early discharge strategies for heart attack patients, showing promising results, but this specific approach is being evaluated for the first time in this context.
