Reversible Diastolic Dysfunction after Long-Term Exogenous Subclinical Hyperthyroidism: A Randomized, Placebo-Controlled Study

Abstract

We conclude that prolonged subclinical hyperthyroidism is accompanied by diastolic dysfunction that is at least partly reversible after restoration of euthyroidism. Because isolated diastolic dysfunction may be associated with increased mortality, this finding is of clinical significance.
