Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 30 to 70 who have been hospitalized for an acute myocardial infarction and diagnosed with severe periodontitis.

Probably not a fit

Patients with other significant health conditions affecting periodontal status or those unable to attend follow-up visits may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter randomized clinical trial investigates the effects of periodontal therapy on inflammatory activity in atheromatous plaques among patients hospitalized for an acute myocardial infarction (AMI). Participants aged 30 to 70 with severe periodontitis will be randomly assigned to receive either specialized periodontal treatment or standard dental care. Both groups will undergo FDG-PET scans to evaluate inflammation in carotid atherosclerotic plaques at the beginning and after 12 months. The study aims to determine if improved oral health can positively impact cardiovascular inflammation.

Why it matters

Potential benefit: If successful, this study could lead to improved cardiovascular outcomes for patients with both severe periodontitis and acute myocardial infarction.

How similar studies have gone: While the specific approach of this study is novel, previous studies have suggested a link between periodontal health and cardiovascular disease, indicating potential for success.
