Relationship of circulating thyroid antibodies to coronary artery disease.

A study of the relationship between circulating thyroid antibodies and coronary artery disease was performed. In 180 patients, the state of the coronary arteries was determined by cardiac catheterization and antithyroglobulin and antimicrosomal antibodies were measured using immunoprecipitation. The prevalence of risk factors for coronary artery disease and the mean age of the groups with and without coronary artery disease were similar. There was no significant difference in the prevalence of thyroid antibodies in patients with or without coronary artery disease.
