An article I just read in Duke Medicine's Health News publication indicated the following: "Too much Thyroid hormone (hyperthyroidism) can trigger the development of atrial fibrillation (AF), and too little hormone (hypothyroidism) is associated with a lower risk of AF, found a Danish study published online on November 27, 2012, in the BRITISH MEDICAL JOURNAL. The observational study followed 586,500 adults who had their first thyroid function test between January 1, 2000 and January 1, 2010. By December 31, 2010, 2.9 percent--more than half of whom were women--had developed AF. The researchers discovered that the risk began to drop as soon as thyroid levels rose above normal, even before the deficit could be detected with a normal thyroid function test or symptoms appeared. The risk of AF increased proportionately as thyroid levels increased: 4.6 of those with hyperthyroidism developed AF. This finding suggests that thyroid levels should be checked in people who develop atrial fibrillation, with higher-than-normal levels as a possible underlying, treatable cause."
I assume this study was done on the general population, not ThyCa patients.
However, as most ThyCa patients thyroid hormone is kept in the hyperthyroid range post TT, I wonder if those patients who develop heart palpitations or other heart issues should be tested for atrial fibrillation?
