Thyroid Hormone Replacement for Hypothyroidism and Acute Myocardial Infarction(ThyroHeart-AMI)

Summary

Based on accumulating evidences showing that hypothyroid status is associated with poor prognosis among acute myocardial infarction (AMI) patients, the study is designed to evaluate whether replacement treatment with levothyroxine could have beneficial effects on patients with AMI and hypothyroidism. This is a multicenter prospective computerized-randomized trial stratified by ejection fraction with a 1:1 ratio to levothyroxine group or standard therapy group.
