V. Marti et al., ACTIVE MYOCARDIAL DAMAGE IN HYPERTHYROIDISM - A CONCURRENT MECHANISM OF HEART-FAILURE REVERSED BY TREATMENT, European heart journal, 16(7), 1995, pp. 1014-1016
A patient with hyperthyroidism, heart failure, and depressed ejection
fraction, in whom myocardial damage was evidenced by In-111-labelled m
onoclonal antimyosin antibodies, is presented. Both myocardial damage
and left ventricular dysfunction disappeared after antithyroid therapy
. This suggests that, in addition to volume overload, heart failure in
hyperthyroidism could be also due to the presence of potentially reve
rsible concurrent myocardial damage.
