People with sub clinical hypothyroidism -- or an under-active thyroid gland without evidence of symptoms -- may have a 65 percent higher risk of heart disease. The recent review of 14 published observational studies in the American Journal of Medicine shed new light on the magnitude of this risk factor -- though researchers hesitate to recommend thyroid screening to healthy adults who do not show symptoms. More extensive clinical studies, such as those that would include patients who have only had a singular vascular episode, are needed for the researchers to be sure -- and thyroxine treatment, commonly given to hypothyroid patients, may prevent future incidence of heart disease.
