normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : many patients using warfarin may be at risk of international normalized ratio fluctuations. this may cause severe massive gastrointestinal or cerebral bleeding. subclinical hypothyroidism in our population is highly prevalent (range from 3.1% to 8.4% for males and females respectively). overt hypothyroidism di...

Background/aim: Hyperthyroidism causes hemodynamic changes that are associated with adverse cardiovascular outcomes. Twenty-four-hour ambulatory blood pressure monitoring recordings provide us with some essential data: BP variability and ambulatory arterial stiffness index (AASI). In this study, we aimed to investigate AASI and short-term BP variability in both overt and subclinical hyperthyroi...

OBJECTIVE Subclinical hyperthyroidism has long-term sequelae that include osteoporosis, cardiovascular morbidity, and progression to overt thyrotoxicosis or thyroid failure. The objective of this study was to evaluate pregnancy outcomes in women with suppressed thyroid-stimulating hormone (TSH) and normal free thyroxine (fT(4)) levels. METHODS All women who presented to Parkland Hospital for ...

this study was performed to evaluate the effect of atenolol on the serum concentration of tt4 and tt3 in subclinical hyperthyroid patients. due to the i n s u fficient information about the effect of atenolol on serum level of these hormones, the aim of this research was to shade some light on the subject. fifteen subclinical hyperthyroid patients entered this study. each patient received 100 m...

CONTEXT Knowledge on the relationship between the autonomic nervous system and subclinical hyperthyroidism is mainly based upon cross-sectional studies in heterogeneous patient populations, and the effect of restoration to euthyroidism in subclinical hyperthyroidism has not been studied. OBJECTIVE We investigated the long-term effects of exogenous subclinical hyperthyroidism on the autonomic ...

BACKGROUND We report the prevalence of coronary artery disease (CAD) associated with subclinical hypothyroidism in older persons. METHODS We investigated the prevalence of subclinical hypothyroidism and its association with dyslipidemia and with CAD in 170 women and 110 men, mean age 75 +/- 9 years, in an academic nursing home. RESULTS Of 280 persons, 18 (6%) had subclinical hypothyroidism,...

Subclinical hyperthyroidism is defined as low or undetectable serum thyrotropin concentration in the presence of levels of free thriiodothyronine and thyroxine within the reference range. Despite the conflicting results from many observational studies, this thyroid disorder has been associated with an increased risk of developing atrial fibrillation, left ventricular hypertrophy, increased hear...

BACKGROUND Several epidemiologic studies have shown a possible association between thyroid function and cognitive decline. Our aim was to evaluate the association of subclinical hyperthyroidism and dementia in a population sample of older people METHODS A cross-sectional study--São Paulo Ageing & Health Study (SPAH)--in a population sample of low-income elderly people > or = 65 years-old to e...

CONTEXT Previous studies have suggested that subclinical abnormalities in thyroid-stimulating hormone levels are associated with detrimental effects on the cardiovascular system. OBJECTIVE To determine the relationship between baseline thyroid status and incident atrial fibrillation, incident cardiovascular disease, and mortality in older men and women not taking thyroid medication.
