Overview
The goal of this clinical trial is to determine if standardized periodontal therapy can effectively slow the progression of aortic valve stenosis in adult patients diagnosed with moderate aortic valve stenosis and coexisting gingivitis or mild-to-moderate periodontitis.
The main questions it aims to answer are: Can periodontal therapy slow the progression of aortic valve stenosis? Is chronic periodontitis an independent risk factor for the accelerated progression of aortic valve stenosis? Researchers will compare a group of patients receiving standardized periodontal therapy to a control group receiving only oral hygiene education to see if periodontal treatment results in a slower progression of aortic valve stenosis.
Participants will undergo initial screening to confirm eligibility based on aortic valve peak velocity and periodontal status. They will then be randomly assigned to either the treatment group, which will receive comprehensive periodontal therapy, or the control group, which will receive only oral hygiene education. Participants will be followed up regularly over a 36-month period, with assessments including echocardiograms to monitor the progression of aortic valve stenosis, periodontal examinations to assess oral health status, and blood tests to measure relevant serum biomarkers. The study will also track any cardiovascular events and adverse events related to the interventions.
