Abstract
The sialic acid/glycosaminoglycan ratio was determined in 35 coronary artery ectasia patients and 35 control subjects to determine the possible role of fluoride in the etiology of the disease. The coronary artery ectasia patients and controls were selected from subjects who underwent coronary angiography. The mean serum sialic acid level was significantly lower in patients with coronary artery ectasia (CAE) than in controls (340.3±28.6 vs. 427.0±15.9 ug/mL, respectively; p<0.001). The mean serum glycosaminoglycan level was significantly higher in patients with CAE than in controls (5,013.1±158.6 vs. 3,833.6±237.1 ug/mL, respectively; p<0.001). The sialic acid/glycosaminoglycan ratio in patients with coronary artery ectasia was significantly lower than in controls (0.068±0.007 vs. 0.111±0.005; p<0.001). There was more than 38.7% reduction in this ratio in patients with CAE when compared with controls. We demonstrated that chronic fluoride exposure has an important role in pathogenesis of coronary artery ectasia.

An assessment of the relationship between excess fluoride intake from drinking water and essential hypertension in adults residing in fluoride endemic areas.
In this study, the relationships between high water fluoride exposure and essential hypertension as well as plasma ET-1 levels were investigated. A total of 487 residents aged 40 to 75 were randomly recruited from eight villages in Zhaozhou County from Heilongjiang Province in China and were divided into 4 groups

Electrocardiogram analysis of patients with skeletal fluorosis
To investigate the degree of myocardial damage resulting from endemic fluorosis, electrocardiograms of 136 skeletal fluorosis patients from an endemic fluorosis area were compared with electrocardiograms of a control group of 40 normal patients from a non-endemic fluorosis area. The results show that fluoride in drinking water consumed over time

The effects of fluoridated water on rat urine and tissue cAMP levels
Male Wistar rats were fed a fluoride deficient diet (less than 0.5 parts/10(6) F), and either distilled water or fluoridated water (1.0 parts/10(6)). By week 3, the control group had urinary excretions of 106 +/- 5 nmol cAMP/day (mean +/- SEM) whereas the experimental group excreted 129 +/- 6 nmol

Ionic plasma fluoride concentrations related to some diseases in patients from a fluoridated community
Little data is available concerning the relationship between variations in ionic plasma fluoride (IPF) concentrations and some diseases, and that which exists is inconclusive. The effect of renal insufficiency is known best, but the relationship between IPF levels and some oedematous diseases and diabetes has hardly been studied at all

Systematic impacts of fluoride exposure on the metabolomics of rats.
Highlights The risk of chronic endemic fluorosis exists in many countries and regions. Comprehensive metabolomic analysis was used to study the effects of fluoride. Multivariate statistics were used to detect metabolite profile changes. Fluoride exposure caused amino acid, fatty acid, and energy metabolism disorders. Fluoride exposure caused oxidative stress,

Fluoride, Blood Pressure and Hypertension
Individuals with blood pressure readings that exceed 140/90 are considered hypertensive. Hypertension can increase the risk of stroke, heart attack, heart failure, aortic aneurysms, and peripheral arterial disease. An association between increased fluoride in ground water and increased prevalence of hypertension has been observed, especially among adult males (Amini et

Fluoride & Arterial Calcification
The major change involved with cardiovascular disease is development of atherosclerosis in critical arteries, which is partially characterized by vascular calcification. The level of coronary artery calcification is thought to be the most important indicator of future cardiovascular events. Increased arterial calcifications have frequently been reported in those with skeletal fluorosis

Fluoride & Electrocardiogram Abnormalities
An electrocardiogram (ECG) is a diagnostic test that measures the electrical activity of the heart. An ECG can reveal heart rate, heart rhythym (i.e. steady or irregular), and the strength and timing of the heart’s natural electrical signals. ECGs are described in terms of “waves” (e.g. amplitude and duration). Problems

Fluoride & Myocardial Damage
Structural damage to the heart resulting from fluoride toxicity has been observed in numerous human and animal studies. The general features of this damage include cloudy swelling, vacuolization or vacuolar degeneration, hemorrhages, interstitial edema, fibrous necrosis, dissolution of nuclei, and thickening of the vessel walls in the heart muscle (Basha

Fluoride & Arteriosclerosis
Healthy arteries are flexible and elastic, allowing efficient transfer of blood and nutrients from the heart to the rest of the body. Arteriosclerosis refers to a stiffening of the arteries, including loss of elasticity. This is a slow, progressive disease that may begin early in life from damage to the
