BACKGROUND The heart was very sensitive to fluctuating thyroid hormone levels. To assess intra-left ventricular (LV) systolic asynchrony in patients with subclinical thyroid dysfunction. METHODS Fifty patients with subclinical hypothyroidism and 40 controls were included. A diagnosis of subclinical hypothyroidism was reached with increased TSH and normal free T4. All subjects were evaluated b...

Thyroid dysfunction is one of the most commonly encountered endocrine abnormalities. The screening of thyroid dysfunction is recommended in Nepal with its high risk population. Many factors are responsible for exacerbating the thyroid dysfunction in the context of Nepal. Therefore, this study was designed to assess the prevalence of thyroid dysfunction in Dhulikhel Hospital-Kathmandu University...

OBJECTIVE The purpose of this study was to determine whether routine screening for subclinical hypothyroidism during pregnancy would be cost-effective. STUDY DESIGN We developed a decision analysis model to compare the cost-effectiveness of 2 screening strategies during pregnancy for subclinical hypothyroidism: (1) no routine screening of serum thyroid-stimulating hormone (TSH) levels (standa...

OBJECTIVE The objective of this study was to investigate the health status of women with overt and subclinical hypothyroidism and relate it to the presence of clinical signs and symptoms of the disease. SUBJECTS AND METHODS A cross-sectional study was conducted on 232 women divided into 3 groups: overt hypothyroidism (n = 14); subclinical hypothyroidism (n = 152), and controls (n = 66). Healt...

Several conditions and drugs induce subclinical hypothyroidism. We report a case of asymptomatic and reversible subclinical hypothyroidism in a 48-year old woman with minor depressive disorder receiving therapy with escitalopram 20 mg daily for six months.

Hypothyroidism denotes deficient production of thyroid hormone by the thyroid gland and can be primary (abnormality in thyroid gland itself) or secondary/central (as a result of hypothalamic or pituitary disease). The term 'subclinical hypothyroidism' is used to define that grade of primary hypothyroidism in which there is an elevated thyroid-stimulating hormone (TSH) concentration in the prese...

Subclinical hypothyroidism, which is defined as elevated thyroid-stimulating hormone (TSH) levels with free thyroxine concentrations within the reference range, is a common disorder that increases with age and affects up to 18% of the elderly, with a higher prevalence in women compared to men. Prospective data have shown an increased risk of coronary heart disease events, heart failure, and car...

NEED AND PURPOSE OF REVIEW Subclinical hypothyroidism is a biochemical diagnosis characterized by raised thyroid stimulating hormone and normal free T4, without clinical features of hypothyroidism. This review analyzes the current evidence to arrive at a consensus and algorithm to manage this condition. METHODS We searched Pubmed, Cochrane and Embase for articles published between 1990 to 201...

BACKGROUND AND OBJECTIVES Subclinical hypothyroidism is associated with endothelial dysfunction and impaired coronary flow reserve. However, the effect of subclinical hypothyroidism or thyroid autoimmunity on variant angina has yet to be determined. SUBJECTS AND METHODS Among 385 consecutive patients without associated cardiovascular risk factors who underwent coronary angiography with the er...

About 30% of children with elevated TSH levels during neonatal screening have a transient form of disorder. On the other hand, it has been reported that subclinical hypothyroidism persists in late childhood in about 30% of children found to be false-positive during neonatal screening. The aim of this study was to determine whether transient thyroid dysfunction and subclinical hypothyroidism det...
