Pre-discharge Flu Vaccine for patients with acute heart problems
Official title: Pre-discharge Influenza Vaccination in Patients Hospitalized for Acute Cardiac Conditions
Run by Wroclaw Medical University · NCT07617376 · Data updated 2026-11-12
This trial tests whether giving an influenza vaccine within 24 hours before hospital discharge helps patients who were treated for acute heart issues stay healthier this season.

Is this trial a fit for you?
✓Likely a good fit
Adults hospitalized for acute cardiac conditions who plan to be discharged within 48 hours and have not yet received a flu vaccine this season.
✕Probably not a fit
Patients who have already received a influenza vaccine this season or who have contraindications to vaccination may not benefit.

What this trial studies
This investigator-initiated, single-center study enrolls adults hospitalized for acute cardiac conditions such as myocardial infarction or acute heart failure and randomizes them to receive an influenza vaccine within 24 hours before discharge. The open-label design compares vaccination timing at discharge versus standard care, aiming to see if pre-discharge vaccination increases protection against flu-related complications. Eligible patients are planning to go home within 48 hours of finishing in-hospital care and have not yet received a flu vaccine for the current season. Outcomes focus on feasibility and potential reduction in recurrent cardiovascular events linked to influenza infection. The study is conducted at Jan Mikulicz Radecki University Hospital in Wroclaw, led by Wroclaw Medical University.
Why it matters
Potential benefit: If successful, pre-discharge vaccination could reduce flu-related complications and provide added protection during a high-risk period after hospital discharge.
How similar studies have gone: Vaccination strategies in hospitalized patients have shown promise in improving uptake, but pre-discharge timing for cardiovascular outcomes is an area with limited evidence.
