Hypothyroidism Produced by Radioactive Iodine (I 131 ) in the Treatment of Euthyroid Patients with Angina Pectoris and Congestive Heart Failure

Abstract

Hypothyroidism, induced by I¹³¹ to lessen the work of the heart, is proposed as a means of treating certain patients with angina pectoris and congestive failure who are refractory to the standard medical measures. Eighteen such patients have been treated. The period of follow-up averages thirteen months. Eight of the 13 patients with angina pectoris and 3 of 5 patients with congestive failure showed worthwhile improvement. In 6 of the 18 patients, the improvement was striking. Tentative criteria for the selection of patients, their pre- and post-treatment management, and detailed descriptions of the results are presented.
