[Thyroid hormones and the poststress changes in the contractile function and ultrastructure of the hypertrophic heart].
The effect of thyroid hormones on stress-induced changes of contractility and ultrastructure of hypertrophied heart, was studied. Small doses of thyroid hormones enhanced the contractility of hypertrophied heart both under stress and without it, and decreased the changes of the Smch/Smf ratio during hypertrophy, preventing these changes during hypertrophy associated with stress.
