Clinical Trial Summary

The goal of this randomized, double-blind, placebo-controlled clinical trial is to investigate the immunological effects of influenza vaccination outside of the influenza season on arterial inflammation in patients with a recent acute myocardial infarction (AMI). The primary objective is to compare the effects of influenza vaccination to those of a placebo in reducing post-myocardial infarction coronary inflammation as measured by coronary computed tomography angiography (CCTA). The main questions it aims to answer are: Does influenza vaccination reduce arterial inflammation as measured by CCTA at week 8 after percutaneous coronary intervention (PCI) in comparison to baseline? Does influenza vaccination modulate systemic inflammation as measured by blood biomarkers and in-vitro challenge tests at week 8 after PCI in comparison to baseline? Researchers will compare the effects of influenza vaccination with those of a placebo.


Clinical Trial Description

Following informed consent patients are randomized in a 1:1 fashion to influenza vaccination or placebo up to 7 days following PCI. Blood tests for immune cell phenotyping and transcriptomic and proteomic analyses will be collected at baseline and 8 weeks after study inclusion. Patients will undergo CTCA at baseline (≤ 7 days of an AMI) and 8 weeks after PCI. ;
