Abstract
In the electrocardiogram of rabbits given sodium fluoride orally, a pattern of myocardial damage was observed, namely depressed ST, inverted T, prolonged QT interval, multifocal ventricular premature contraction, bundle branch block, and pulmonary P. Histologically, regressive degeneration, cellular infiltration, hyperemia, hemorrhages and thickening of vessel wall were noted in the heart muscle.

[Experimental study on rat cardiac toxicity induced by sodium fluoride of different dosages].
The cardiotoxic effect of various dosage of sodium fluoride was investigated. Three-week-old male Wistar rats were fed on normal fodder and distilled water containing different dosages (0, 25, 50, 100 and 150 mg/litre) of sodium fluoride for 6 months to establish an animal model of chronic fluorosis. Electrocardiogram (ECG) was

Rutin potentially attenuates fluoride induced oxidative stress mediated cardiotoxicity, blood toxicity and dyslipidemia in rats
The present study was undertaken to evaluate cardio protective effect of rutin against sodium fluoride-induced oxidative stress mediated cardio toxicity and blood toxicity. Cardiac injury was induced by daily administration of sodium fluoride 600ppm in distilled water for 4 weeks. The animals exposed to NaF exhibited a significant increase in

Effects of chronic ingestion of sodium fluoride on myocardium in a second generation of rats
Possible effects of long term exposure (6 months) to sodium fluoride (NaF) through drinking water on the morphology and biochemistry of myocardial tissue in second generation adult male rats were investigated. Wistar strain female and male rats were reared until the second generation of rats obtained, during which they were

Acute fluoride poisoning alters myocardial cytoskeletal and AMPK signaling proteins in rats
BACKGROUND: Our previous findings revealed that increased oxidative stress, apoptosis and necrosis were implicated in acute fluoride (F-) induced cardiac dysfunction apart from hypocalcemia and hyperkalemia. Cardiac intermediate filaments (desmin and vimentin) and cytoskeleton linker molecule vinculin plays an imperative role in maintaining the architecture of cardiac cytoskeleton. In addition,

Study on the cardiovascular system damage in skeletal fluorosis patients
Objective To understand the damage to the cardiovascular systems of patients with different degrees of skeletal fluorosis after stopping fluorine exposure. Methods 65 patients with mild, moderate and severe skeletal fluorosis and 23 subjects without skeletal fluorosis as the control group were selected for detailed inquiry of cardiovascular disease history,

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 & 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, 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 & 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
