Abstract

1) The author examined inhabitants of a high fluoride zone (Shionoe village, Kagawa Prefecture, and Odani villAge, Sanyo town, Okayama Prefecture). ln residents of these zones , greater myocardial damage was detected electrocardiographically and dilatation of the cardiac sillouette roentgenograpbically than in n0n-fluoride areas. 2) The myocardial damage appears to be related to the high fluoride content of drinking water.

  • 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,

  • Changes of the heart muscle due to chronic fluorosis. Part 2: Experimental studies on the effects of sodium fluoride upon the heart muscle of rabbits

    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

  • Impact of chronic fluorosis on left ventricular diastolic and global functions.

    Sixty three patients with endemic fluorosis (36 males/27 females; mean age 33.9+/-8.6years) and 45 age, sex and body mass index (BMI) matched healthy controls (30 males/15 females; mean age 32.7+/-8.8years) were included in this study. Basic echocardiographic measurements, left ventricular diastolic parameters and left ventricular myocardial performance index (MPI) were

  • 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 & 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, 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 & 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
