[Hypophyseo-thyroid system in stress stenocardia and myocardial infarct with favorable and unfavorable course].

The condition of the hypophyseal-thyroid system in patients with angina of effort and in those with myocardial infarction in the acute stage was studied by determining the content in the blood of the thyrotropic hormone (TTH), thyroxin (T4), and triiodthyronine and 2-hour iodine uptake by the thyroid. It was found that the functional condition of the hypophyseal-thyroid system in patients with angina of effort differs essentially from that in patients with myocardial infarction. The behavior of the thyroid system in myocardial infarction is equivocal and correlates with the character of the course followed by the disease.
