BACKGROUND Periodontal disease is common among adults in the US and is a potential source of chronic inflammation. Recent data have suggested
an important role for chronic inflammation in the development of coronary heart disease (CHD).
OBJECTIVE To aid the United States Preventive Services Task Force (USPSTF) in evaluating whether periodontal disease is an independent
novel risk factor for incident CHD.
METHODS Studies were identified by searching Medline (1966 through March 2008) and reviewing prior systematic reviews, reference lists,
and consulting experts. Prospective cohort studies that assessed periodontal disease, Framingham risk factors, and coronary
heart disease incidence in the general adult population without known CHD were reviewed and quality rated using criteria developed
by the USPSTF. Meta-analysis of good and fair quality studies was conducted to determine summary estimates of the risk of
CHD events associated with various categories of periodontal disease.
RESULTS We identified seven articles of good or fair quality from seven cohorts. Several studies found periodontal disease to be independently
associated with increased risk of CHD. Summary relative risk estimates for different categories of periodontal disease (including
periodontitis, tooth loss, gingivitis, and bone loss) ranged from 1.24 (95% CI 1.01–1.51) to 1.34 (95% CI 1.10–1.63). Risk
estimates were similar in subgroup analyses by gender, outcome, study quality, and method of periodontal disease assessment.
CONCLUSION Periodontal disease is a risk factor or marker for CHD that is independent of traditional CHD risk factors, including socioeconomic
status. Further research in this important area of public health is warranted. 相似文献

Many epidemiological studies have indicated that periodontitis is an important risk factor for coronary heart disease (CHD). We examined whether plasma antibody levels to 3 major periodontal pathogens, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Prevotella intermedia predicted the risk of CHD events. A nested case-control research design (case: n = 191, control: n = 382), by matching gender, age, study area, date of blood collection, and time since last meal at blood collection, was employed in a large cohort of Japanese community residents.Antibody levels of periodontopathic bacteria were associated with risk of CHD after adjusting for BMI, smoking status, alcohol intake, history of hypertension, history of diabetes mellitus, exercise during leisure time, and perceived mental stress. The association was different by age subgroup. For subjects aged 40-55 years, the medium (31.7-184.9 U/mL) or high tertile plasma antibody level (> 184.9 U/mL) of A. actinomycetemcomitans showed higher risk of CHD (medium: OR = 3.72; 95% CI = 1.20-11.56, high: OR = 4.64; 95% CI = 1.52-14.18) than the low tertile level (< 31.7 U/mL). The ORs of CHD incidence became higher with an increase in IgG level of A. actinomycetemcomitans (P for trend = 0.007). For subjects aged 56-69 years, the high tertile level (> 414.1 U/mL) of P. intermedia was associated with higher risk of CHD (OR = 2.65; 95% CI = 1.18-5.94) in a dose-response fashion (P for trend = 0.007). The possible role of periodontopathic bacteria as a risk factor for CHD incidence was suggested by the results of this study by the elevated antibody level to these bacteria with the increased risk of CHD. 相似文献

脂联素是近年来新发现的一种脂肪因子,血浆中脂联素含量丰富。在有冠心病危险因素,如糖尿病、代谢综合征的病人中,脂联素水平明显下降。因具有抗炎、抗动脉粥样硬化作用脂联素近来成为研究的热点,脂联素浓度与冠心病特别是急性冠脉综合征进程密切相关,脂联素浓度测定有可能成为冠心病危险性的评估因素。通过药物干预提高血浆脂联素浓度可能成为一种新的冠心病治疗方法。 相似文献

Aim: Evidence is lacking about whether urinary stones are associated with the subsequent risk of cardiovascular diseases. Herein, we investigated the association between history of urinary stones and the risk of coronary heart disease (CHD) and stroke among middle-aged Japanese.Methods: This cohort study included 89,037 Japanese men and women (45–74 years) registered in the Japan Public Health Center-based prospective study. Cox proportional hazard models were used to calculate the hazard ratios (HRs) and their 95% confidence intervals (CIs) for incident CHD and stroke among Japanese adults with a self-reported history of urinary stones compared with those without it. The following covariates were included in the regression models: age, sex, area, body mass index, and histories of hypertension, diabetes, hyperlipidemia, smoking habit, alcohol intake, and physical activity.Results: In total, 1.31% of Japanese adults reported a positive history of urinary stones. Throughout a median follow-up period of 12 years, 1.16% of Japanese adults developed CHD, and 4.96% developed stroke. No associations were detected between history of urinary stones and the risk of CHD (HR 1.04; 95% CI: 0.64–1.67), stroke (HR 0.92; 95% CI: 0.71–1.20), or total CVD (HR 0.95; 95% CI: 0.75–1.19). Younger urinary stone formers (45–59 years) tended to have a higher, though statistically insignificant, risk of CHD than older urinary stone formers (60–74 years): [(HR 1.15; 95% CI: 0.61–2.15) versus (HR 0.83; 95% CI: 0.40–1.76)], respectively.Conclusion: The history of urinary stones was shown to be not associated with the risk of CVD among Japanese adults. 相似文献

目的:探讨脂联素(APN)水平及其单核苷酸基因多态性(SNP)+45T/G和+276G/T 2个位点与冠心病(CHD)的关系.方法:将195例研究对象分为正常对照组和CHD组,采用实验-对照研究方法,应用酶联免疫吸附法(ELISA)及聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术,对血浆APN浓度及APN 2个位点基因多态性进行检测.结果:2组比较,CHD组APN降低(P<0.05);CHD组SNP+45 TG+GG基因型和G等位基因的分布频率明显低于正常对照组,差异具有统计学意义(P<0.05);基因SNP+276多态性位点各基因型频率与等位基因频率在2组之间差异均无统计学意义(P>0.05).结论:CHD患者APN水平下降,SNP+45 G等位基因可能为CHD的保护因素;SNP+276位点基因多态性可能与CHD的发生无明显相关性. 相似文献
