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.

Association of Hypertension, Body Mass Index, and Waist Circumference with Fluoride Intake; Water Drinking in Residents of Fluoride Endemic Areas, Iran.
Hypertension is becoming a global epidemic for both rural and urban populations; it is a major public health challenge in Iran. Fluoride can be a risk factor for hypertension. Cross-sectional analysis was conducted in two study areas to assess the relation of fluoride with blood pressure prevalence, BMI, waist circumference,

Fluoridation and mortality - an epidemiologic study of Pennsylvania Communities
The diabetes mortality rate was lower (37.0) for the fluoridated areas than for the unfluoridated (45.2); this difference was statistically significant (P<0.01). Thus, the adjusted mortality rates for all causes and for cerebrovascular diseases and diabetes mellitus all tended to be higher in the unfluoridated areas than in the fluoridated. ...

Heart deaths and fluoridation
In the city of Antigo, Wisconsin, fluoridation of the public water supplies was initiated in 1949. ·It was discontinued in November 1960, and reinstituted in October 1965, A striking increase in the rate of deaths from heart disease occurred. in Antigo hnmediately following the introduction of fluoridation in 1949 and

Studies on the toxicology of fluorine compounds. I. Histological and histochemical investigations on the liver, heart, lungs, and stomach of rats exposed to hydrogen fluoride
The liver, heart, lungs, and stomach of rats exposed to hydrogen fluoride were studied. Histological examination showed partial liver necrosis and emphysema. Using histochemical methods the effect of fluorine ions was found in: a reduction of the activity of succinic and beta-hydroxybutyric dehydrogenases in the liver, heart muscle, superficial and

Fluoride stimulates in vitro vascular prostacyclin synthesis: interrelationship of G proteins and protein kinase C
The role of G proteins in mediating adrenoceptor-prostacyclin synthesis coupling was investigated using the G protein activator, sodium fluoride. Sodium fluoride (NaF) stimulated in vitro rat aortic prostacyclin (PGI2) synthesis (EC50 = 5 x 10(-3) mol.l-1), an action inhibited completely by the presence of EDTA (10(-2) mol.l-1). The NaF-PGI2 dose-response

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

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 & 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 & 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, 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
