Periodontal conditions in patients with coronary heart disease: A case-control study
2012 (English)Manuscript (preprint) (Other academic)
Aim: To study if CAD-related morbidity and mortality (endpoints; myocardial infarction, coronary artery revascularization or CAD-related death) during 8-years follow was related to baseline periodontal status.
Material and methods: In 2003, periodontal status was examined in 161 CAD patients who underwent percutaneous coronary intervention or coronary artery by-pass graft due to significant stenosis in the coronary arteries, and in 162 control subjects without CAD history. Eight years later, 126 CAD patients and 121 controls were periodontally re-examined. The groups were classified into five categories as per periodontal disease experience (Hugoson & Jordan 1982). Cause of death due to CAD was obtained from Sweden’s death register. Myocardial infarction and coronary artery revascularization procedures were confirmed by review of medical records.
Results: No significant differences were found among CAD patients with / without CAD related endpoints and periodontal disease experience group (p=0.7). Significant differences were found at the final examination in periodontitis prevalence and severity (p=0.001), number of teeth (p=0.006), pockets 4-6 mm (p=0.016), bleeding on probing (p=0.001) and radiographic bone level between (p=0.042) between CAD-patients and controls.
Conclusion: The study results did not show a significant association between CAD outcomes after 8 years and periodontal status at baseline. Further long-term prospective studies are needed to show whether periodontitis can be considered a risk or prognostic factor for CAD.
