Abstract
<p style="text-align:justify"><span style="font-size:12pt"><span style="background-color:white"><span style="font-family:"Times New Roman",serif"><strong><span style="color:#0d0d0d">Introduction:</span></strong><br /> <span style="color:#0d0d0d">Acute coronary syndrome (ACS) is associated with substantial morbidity and mortality. Accumulating evidence suggests that influenza vaccination reduces cardiovascular events, yet vaccine uptake remains suboptimal. Hospitalisation for ACS may represent a teachable moment to improve immunisation coverage.</span></span></span></span></p> <p style="text-align:justify"><span style="font-size:12pt"><span style="background-color:white"><span style="font-family:"Times New Roman",serif"><strong><span style="color:#0d0d0d">Objectives:</span></strong><br /> <span style="color:#0d0d0d">To compare complete influenza vaccination coverage before and after an ACS event and to assess whether ACS hospitalisation was associated with increased vaccination uptake.</span></span></span></span></p> <p style="text-align:justify"><span style="font-size:12pt"><span style="background-color:white"><span style="font-family:"Times New Roman",serif"><strong><span style="color:#0d0d0d">Methods:</span></strong><br /> <span style="color:#0d0d0d">We conducted a retrospective study of consecutive patients admitted to the cardiac intensive care unit of a tertiary centre. Demographic and clinical characteristics were retrieved from medical records. Complete influenza vaccination status before ACS and after discharge was recorded for each patient. Paired proportions were compared using McNemar’s test.</span></span></span></span></p> <p style="text-align:justify"><span style="font-size:12pt"><span style="background-color:white"><span style="font-family:"Times New Roman",serif"><strong><span style="color:#0d0d0d">Results:</span></strong><br /> <span style="color:#0d0d0d">A total of 126 patients met inclusion criteria. Thirty-four died during or after hospitalisation, leaving 92 survivors with documented influenza vaccination status. The cohort was predominantly male (76.2%) with a mean age of 71.6?±?11.4 years and a high prevalence of cardiovascular risk factors, including hypertension (81.7%), dyslipidaemia (81.7%), and type 2 diabetes (47.6%). Before ACS, 15 patients (16.3%) had completed influenza vaccination. After ACS, this proportion increased to 45.7% (p?<?0.001), indicating that a substantial number of previously unvaccinated patients were immunised following the index event. Nonetheless, 35.9% of survivors remained unvaccinated after ACS and 10.9% explicitly refused vaccination.</span></span></span></span></p> <p style="text-align:justify"><span style="font-size:12pt"><span style="background-color:white"><span style="font-family:"Times New Roman",serif"><strong><span style="color:#0d0d0d">Conclusions:</span></strong><br /> <span style="color:#0d0d0d">In this high-risk ACS population, influenza vaccination coverage nearly tripled after the acute event, supporting the concept of ACS hospitalisation as an opportunity to initiate secondary-prevention immunisation. However, more than one-third of patients remained unvaccinated, underscoring persistent missed opportunities and the need for structured in-hospital vaccination strategies and systematic post-discharge follow-up to optimise influenza immunisation in ACS patients.</span></span></span></span></p>
