N1 - Acknowledgements The authors thank the laboratory and administrative staff at the Institute of Dentistry and the Institute of Medical Sciences of the University of Aberdeen for their help. We are grateful to Dr Pirkko Pussinen (Institute of Dentistry, University of Turku, Finland) for sharing the P. gingivalis-antibody positive serum samples and a detailed ELISA protocol. We would like to thank all Consultant Cardiologists at Aberdeen Royal Infirmary for identifying suitable patients during the acute on-call: Dr Andrew Hannah, Dr Andrew Stewart, Dr Adelle Dawson, Dr Deepak Garg, Dr Paul Broadhurst, Dr Nicola Ryan. Lastly, we are grateful to all the participating patients.

N2 - To establish the role of periodontal pathobionts as a risk factor for myocardial infarction, we examined the contribution of five periodontal pathobionts and their virulence genes’ expressions to myocardial injury (Troponin-I) and coronary artery disease burden (SYNTAX-I scores) using hierarchical linear regression. Pathobiont loads in subgingival-plaques and intra-coronary-thrombi were compared. Troponin-I release increased with one 16S rRNA gene copy/ng DNA of Porphyromonas gingivalis (β = 6.8×10-6, 95% CI = 1.1×10-7-2.1×10-5), one-fold increased expressions of fimA (β = 14.3, 95% CI = 1.5-27.1), bioF-3 (β = 7.8, 95% CI = 1.1-12.3), prtH (β = 1107.8, 95% CI = 235.6-2451.3), prtP (β = 6772.8, 95% CI = 2418.7-11126.9), ltxA (β = 1811.8, 95% CI = 217.1-3840.8), cdtB (β = 568.3, 95% CI = 113.4-1250.1), all p < 0.05. SYNTAX-I score increased with one 16S rRNA gene copy/ng DNA of Porphyromonas gingivalis (β = 3.8×10-9, 95% CI = 3.6×10-10-1.8×10-8), one-fold increased expressions of fimA (β = 1.2, 95% CI = 1.1-2.1), bioF-3 (β = 1.1, 95% CI = 1-5.2), prtP (β = 3, 95% CI = 1.3-4.6), ltxA (β = 1.5, 95% CI = 1.2-2.5), all p < 0.05. Within-subject Porphyromonas gingivalis and Tannerella forsythia from intra-coronary-thrombi and subgingival-plaques correlated (rho = 0.6, p < 0.05). Higher pathobiont load and/or upregulated virulence are risk factors for myocardial infarction.Trial registration: ClinicalTrials.gov Identifier: NCT04719026
