Impact of Treating Severe Periodontitis on Inflammatory Activity of Atheromatous Plaques in Patients With Acute Myocardial Infarction (AMI)

Multicenter randomized clinical trial with two arms in patients hospitalized for an AMI nested in the Frenchie registry. Periodontal therapy is performed by periodontists in the intervention group versus treatment by dental surgeons as part of their usual practice in the control group. For the intervention group, periodontal management will be carried out for a maximum of 6 months after randomisation, prolonged by a follow-up of 6 months including a maintenance visit at M9. All patients will have an FDG-PET at M0 and M12 for evaluation of inflammation on carotid atherosclerotic plaques.

Effectiveness of Periodontitis Treatment on the Metabolic Activity of Symptomatic Carotid Atherosclerotic Plaque Responsible for Ischemic Stroke

Cardiovascular disease is the world's leading cause of death. Atherothrombosis is a common cause of ischemic stroke. A strong epidemiological link has been established between periodontitis and the risk of stroke. It shares common risk factors with atherothrombosis, and its severe form is associated with low-grade systemic inflammation and daily low-intensity bacteremia. Atherothrombosis is a frequent cause of ischemic stroke. Periodontal bacteria have been found within atheromatous plaques, correlated with a greater risk of rupture. Thus, periodontitis could be a modifiable risk factor for atherothrombosis and future vascular events: its early diagnosis and treatment could have a major impact on cardiovascular prevention. Hypothesis: In patients with periodontitis who have had an ischemic stroke, periodontal treatment may reduce atherosclerotic plaque activity.
