Periodontal disease and coronary heart disease risk 总被引:14,自引:0,他引:14
CONTEXT: Research has suggested a relationship between periodontal disease and coronary heart disease (CHD), but data on the association between these 2 common conditions are inconclusive due to the possibility of confounding. OBJECTIVE: To evaluate the risk of CHD in persons with periodontitis, gingivitis, or no periodontal disease. DESIGN: Prospective cohort study. SETTING: The First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study, conducted in 1982-1984, 1986, 1987, and 1992. PARTICIPANTS: A total of 8032 dentate adults aged 25 to 74 years with no reported history of cardiovascular disease, including 1859 individuals with periodontitis, 2421 with gingivitis, and 3752 with healthy periodontal tissues. MAIN OUTCOME MEASURE: First occurrence of death from CHD or hospitalization due to CHD, or revascularization procedures, obtained from death certificates and medical records, by baseline periodontal status. RESULTS: During follow-up, 1265 individuals had at least 1 CHD event, including CHD fatality (n = 468) or at least 1 hospitalization with a diagnosis of CHD (n = 1022), including coronary revascularization procedures (n = 155). After adjustment for known cardiovascular risk factors, gingivitis was not associated with CHD (hazard ratio, 1.05; 95% confidence interval, 0.88-1.26), while periodontitis was associated with a nonsignificant increased risk for CHD event (hazard ratio, 1. 14; 95% confidence interval, 0.96-1.36). CONCLUSION: This study did not find convincing evidence of a causal association between periodontal disease and CHD risk. JAMA. 2000;284:1406-1410. 相似文献

Chagas disease is the clinical condition triggered by infection with the protozoan Trypanosoma cruzi. The infection is transmitted by triatomine insects while blood feeding on a human host. Field studies predict that one third of an estimated 18 million T cruzi-infected humans in Latin America will die of Chagas disease. Acute infections are usually asymptomatic, but the ensuing chronic T cruzi infections have been associated with high ratios of morbidity and mortality: Chagas heart disease leads to unexpected death in 37.5% of patients, 58% develop heart failure and die and megacolon or megaoesophagus has been associated with death in 4.5%. The pathogenesis of Chagas disease appears to be related to a parasite-induced mutation of the vertebrate genome. Currently, treatment is unsatisfactory. 相似文献
