Objective: With the widespread administration of the BioNTech mRNA-based COVID-19 vaccine, there is a need to evaluate its potential effects on cardiovascular health, particularly its association with myocardial infarction (MI). This study aimed to investigate the relationship between BioNTech vaccination and MI, as well as its impact on clinical and angiographic parameters.
Methods: A retrospective analysis was conducted at the Eskisehir Osmangazi University, Eskisehir City Hospital, between April 2020 and May 2023 on a cohort of 1 151 patients hospitalised with MI. The patients were stratified into a BioNTech+ (vaccinated) and a BioNTech- (unvaccinated) groups. Medical records were reviewed for demographic information, clinical data and angiographic findings. Statistical analyses were performed, including logistic regression models adjusting for potential confounders.
Results: The BioNTech- group had a higher mean number of percutaneous transluminal coronary angioplasty procedures and stents compared to the BioNTech+ group. Haematological parameters and lipid profiles showed some discrepancies between the two groups. The BioNTech- group had higher white blood cell and platelet counts, while also exhibiting a higher mean low-density lipoprotein cholesterol level. The prevalence of co-morbidities and cardiovascular risk factors differed between the groups.
Conclusion: This study found associations between the BioNTech vaccination and clinical and angiographic parameters in patients with MI.
