Thyroxine therapy in hypothyroid patients undergoing coronary revascularization: A retrospective analysis

In our experience, coronary artery surgery in hypothyroid patients has not been accompanied by either perioperative or early or late postoperative mortality. No major complications of surgery were seen during the immediate convalescent period. Maintenance of the hypothyroid state up to the time of surgery was not associated with an increase in either morbidity or mortality. The possible induction of myocardial infarction in four of the pretreated patients, however, could be considered a major disadvantage of the policy of treating with thyroid hormone before revascularization.
