Background: Nowadays, cardiovascular diseases (CVDs) are among the most common causes of mortalities worldwide. Parathyroid hormone (PTH) has an important role in the pathogenesis of CVDs. The aim of the current study was to compare serum PTH levels between patients with acute myocardial infarction (MI), unstable angina, and normal coronary function.
Methods: This descriptive and analytic study was performed on patients with acute MI, unstable angina, and normal coronary function visiting Imam Ali Hospital of Kermanshah city in Iran, during years 2016 to 2017. Data collection was done from December 2017 to March 2018. Of the patients who met inclusion criteria, 120 were selected by accessible sampling and were allocated into three groups. Serum level of PTH was determined in the three groups.
Results: Among the studied subjects, females and males comprised 43 (35.8%) and 77 (64.2%) respectively. Among those with normal coronary function, 22 (55%) and 18 (45%) were females and males respectively. In acute MI group, women and men comprised 8 (20%), and 32 (80%) respectively. Finally, males and females constituted 13 (32.5%) and 27 (67.5%) in unstable angina group. Based on this study, the overall mean serum PTH level was obtained 18.32 pg/ml. The highest PTH level was observed in individuals with normal coronary function, while the lowest level was recorded in patients with unstable angina. There was a significant difference in mean serum parathyroid hormone levels between the study groups in those with no history of smoking.
Conclusion: Our results indicated that parathyroid hormone serum level can be associated with cardiovascular diseases including unstable angina. There were significant differences in the means of parathyroid hormone level between the studied groups depending on the presence or absence of hyperlipidemia. In vitro evaluation of parathyroid hormone level in suspected subjects should be performed in the case of myocardial infarction, unstable angina and normal coronary, prevented from these diseases by testing.
