Being Treated With Too Much Medication May Lead To Increased Risk Of Atrial Fibrillation In Patients With Hypothyroidism,

reports that research indicates that “for patients with hypothyroidism, being treated with too much medication could lead to an increased risk of atrial fibrillation.” Researchers found that “elevated levels of the thyroid hormone free thyroxine (free T4) – even within the upper levels of normal reference ranges – were associated with an increased risk of atrial fibrillation in the study, suggesting the possible need for redefining the safest reference ranges in hypothyroidism treatment.” The findings were presented at the American Heart Association Scientific Sessions 2018. https://login.medscape.com/login/sso/getlogin?urlCache=aHR0cHM6Ly93d3cubWVkc2NhcGUuY29tL3ZpZXdhcnRpY2xlLzkwNDc4NQ==&ac=401
