Abstract
Unstable angina (UA) is situated in a spectrum with myocardial infarction (MI) at one end of it and stable angina at the other end. To determine the clinical and paraclinical characteristics of unstable angina this study was designed.
Materials and Methods: Two hundred patients with definite UA who were hospitalized at cardiac care units (CCU) in Yazd were enrolled in this cross- sectional study. Clinical and para-clinical characteristics including class of severity of angina, clinical circumstances, drugs, risk factors, changes in ECG, and patient's condition at the time of leaving hospital were evaluated.
Results& Conclusions: The average of age of patients was 61.85 years and 57% of them were female and 43% were male. The most prevalent risk factor among men was smoking (48.8%) and among women was hypertension (62.8%). According to Braunwald suggestion, patients were divided into 3 classes based on the severity of their diseases. Frequency distribution of patients in classes I,H and III were 24.5%, 4% and 71.5%, respectively. Normal ECG, was observed in 24.5% of subjects at the time of hospitalization and in 67% of patients when leaving hospitals. Frequency distribution based on the risk stratification was 22.5%, 58.5% and 19% in the low, medium and high risk groups, respectively. During hospitalization, acute myocardial infarction (AMI) was seen in 3.5% of individuals that majority of them belonged to class III of angina.

Abstract
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.
