Serum parathyroid hormone as a potential novel biomarker of coronary heart disease.

Objective: This study aimed to evaluate the relationships between serum parathyroid hormone (PTH) and coronary heart disease (CHD).

Methods: From July 2011 to February 2013, a total of 79 CHD patients and 94 normal control patients with ages ranging from 25 to 79 years were included in this study. Serum PTH level and common risk factors of CHD (age, gender, cholesterol, glycosylated hemoglobin [HbA1c], blood pressure [BP], history of diabetes, smoking, and body mass index) were investigated.
