Hypothyroidism linked to heart disease
A common condition like an under-functioning thyroid called subclinical hypothyroidism may raise the risk of heart disease in people.
Heart disease developed 2.6 times more frequently among participants with subclinical hypothyroidism than those with normal thyroid function. Men were more likely to be affected than women. The prevalence of heart disease was increased to a greater extent in men (3.7 fold) than in women (1.6 fold) with subclinical hypothyroidism. During the 10 years following thyroid testing, survival was lower in men (but not women) with subclinical hypothyroidism. Receptors for thyroid stimulating hormone have been recently reported to express on coronary arteries as well as on fat cells that secrete various factors that affect the development of atherosclerosis. In this way, elevated thyroid stimulating hormone levels may induce heart disease in subclinical hypothyroidism, therefore people suffering with it should be watched for signs of heart trouble.
