Periodontal condition in Japanese coronary heart disease patients: A comparison between coronary and non-coronary heart diseases.

Objective: The aim of this clinical trial was to assess the relationship between periodontal bacterial burden and coronary heart disease (CHD) in Japanese population.

Background: Many epidemiological reports suggest that periodontitis is a risk factor for CHD; however, the influence of each periodontal bacterium and periodontal condition in Japanese CHD patients is unclear.

Methods: We studied 897 patients with cardiovascular diseases in Tokyo Medical and Dental University Hospital from May 2012 to August 2015.

Increased Oral Porphyromonas gingivalis Prevalence in Cardiovascular Patients with Uncontrolled Diabetes Mellitus.

The aim of this study was to determine the correlation between periodontopathic bacteria and diabetes mellitus (DM) status in cardiovascular disease (CVD) subjects.DM is associated with the progression of periodontitis. Several epidemiological studies have suggested that periodontitis may be a risk factor for CVD.

Japanese Cardiovascular Disease Patients with Diabetes Mellitus Suffer Increased Tooth Loss in Comparison to Those without Diabetes Mellitus -A Cross-sectional Study.

Objective Tooth loss is an irreversible condition that reflects the end-stage of oral diseases, including periodontitis. Although periodontitis is a major factor in the progression of diabetes mellitus (DM) and cardiovascular disease (CVD), no previous studies have compared tooth loss in CVD patients with and without DM. Methods The subjects included CVD patients with (n=94) and without (n=145) DM who attended Tokyo Medical and Dental University Hospital.

Detrimental effects of specific Periodontopathic bacterial infection on tachyarrhythmia compared to Bradyarrhythmia.

Background: Tachyarrhythmia (TA) and bradyarrhythmia (BA) are cardiac rhythm disorders that result in the decline of quality of life. While patients with periodontitis are at a high risk of cardiovascular disease (CVD), little causal information between TA and BA has been provided to date. To assess the relationship, periodontal bacterial infection in patients with TA or BA was evaluated.

Periodontitis deteriorates peripheral arterial disease in Japanese population via enhanced systemic inflammation.

Peripheral arterial disease (PAD) is a common manifestation of arterial stenosis of the extremity that reduces arterial flow. While patients with periodontitis are at a high risk of PAD, little causal information has been provided to date. To clarify the relationship, we conducted this cross-sectional study.

The periodontal pathogen Aggregatibacter actinomycetemcomitans affects experimental autoimmune myocarditis in mice.

Recent reports assert that dental health is linked to an increased risk of cardiovascular disease. It is well known that Aggregatibacter actinomycetemcomitans (A.a.

High incidence of Aggregatibacter actinomycetemcomitans infection in patients with cerebral infarction and diabetic renal failure: a cross-sectional study.

Background: Recent epidemiological studies suggest that periodontitis is a major risk factor for renal failure and cerebral infarction. The aim of this study was to evaluate the association among periodontitis, renal failure, and cerebral infarction, focusing on microbiological and immunological features.

Methods: Twenty-one patients treated with hemodialysis (HD) were enrolled in this study.

Toll-like receptor-2 plays a fundamental role in periodontal bacteria-accelerated abdominal aortic aneurysms.

Background:  Periodontopathic bacteria are detected at a high rate in specimens obtained from the aortic walls of patients with abdominal aortic aneurysm (AAA) and are involved in AAA development. The purpose of this study was to clarify the role of Toll-like receptors (TLRs), which are key receptors of virulence factors of many periodontal bacteria, on periodontopathic bacteria-accelerated AAA progression.

Methods And Results:  AAA was produced by peri-aortic application of 0.

Periodontal bacteria aggravate experimental autoimmune myocarditis in mice.

Periodontitis is one of the most common infections in humans. Recently, published reports assert that periodontitis is associated with cardiovascular disease. Although it is said that viral, bacterial infections and autoimmune diseases may be the cause of myocarditis, the pathogenesis of it remains unclear.

Periodontal pathogen Aggregatibacter actinomycetemcomitans deteriorates pressure overload-induced myocardial hypertrophy in mice.

Although a relationship between periodontitis and myocardial hypertrophy has been reported, the precise mechanism has not been clarified. The purpose of this study was to investigate the association between periodontal infection and myocardial hypertrophy. Transverse aortic constriction (TAC) was performed.
