Abstract:
Objective To study the relationship between the thyroid dysfunction and coronary artery disease (CAD). Methods Two thousands and twelve patients,diagnosed as CAD by coronary angiography from January 2003 to February 2010 in Peking Union Hospital,were enrolled into this study and divided into normal thyroid function, hyperthyroidism, and hypothyroidism groups. The thyroid function data and the coronary angiography findings were compared among three groups. Results The incidence rates of hypertension (40%vs. 69. 4% vs. 78.6%, x2 = 12. 331, P = 0. 01) and hyperlipemia(20. 0% vs. 67.4% vs. 85.7%, x2 =12. 331 ,P=0. 002) in hyperthyroidism patients were significantly lower than normal thyroid function patients and hypothyroidism patients, but no significant differences were found in the comparison of diabetes incidence rates among three groups (20. 0% vs. 41.6% vs. 35.7%, x2 = 2. 114,P =0. 347). According to the coronary angiography findings, we found that the incidence rate of CAD of hypothyroidism patients was higher than hyperthyroidism patients(71.0% vs. 55. 2%, x2. = 1. 804, P = 0. 179), but the difference didn' t reach statistically significant level. Two hyperthyroidism patients had coronary artery spasm and acute myocardial infarction. Conclusion Hypothyroidism had more promotion effect on coronary artery disease than hyperthyroidism,but higher serum thyroxin level increased the risk of coronary spasm and the probability of acute myocardial infarction,which could be well adjusted by medication treatment.
