Abstract

Comparative study on STI of populations in regions mildly and severely affected by endemic fluorosis demonstrated significant differences between these two affected regions in the detection rate of abnormal STI as well as QS₂ and PEP/LVET, indicating that endemic fluorosis may injure the heart.

    Objective: This study was carried out to analyse the electrocardiogram (ECG) in patients with endemic fluorosis. Methods: Fifty six patients with endemic fluorosis and 44 age, sex and body mass index (BMI) matched healthy controls with normal fluoride intake underwent standart 12-lead ECG, urine fluoride level and serum sodium, potassium,

    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

    Objective: To analyze the damage caused by hydrofluoric acid to the health of operating workers and to explore health monitoring indicators. Method: Occupational health examinations were carried out on 536 hydrofluoric acid operating workers from the etching process at a certain factory, and 256 persons in the control group. Results: Among the

    Effects of fluoride (F) on electrocardiogram (ECG) values were determined in ten healthy adult male New Zealand white rabbits. After the initial ECG values were measured, the rabbits were administered 20 mg NaF/kg body weight by oral intubation for two months, and the new ECG values were determined. There was

  • 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

  • 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 & 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
