Abstract
ABSTRACT
INTRODUCTION: Unstable angina is a pre-infarction state. Patients with unstable angina should be carefully managed for preventing acute myocardial infarction. This research was aimed to identify incidence rate of myocardial infarction and it`s relation with CRP in patients with unstable angina.
MATERIALS & METHODS: This was a cross-sectional study. Subjects were all patients with unstable angina admitted in CCU of Tohid hospital in Sanandaj. Myocardial infarction was confirmed by laboratory tests (AST-LDH-CPK-CRP) and electrocardiogram (ECG).
RESULTS: Of 757 admitted patients, 418 cases (55.2%) were female and 339 cases (44.8%) were male. Of all patients, 231 cases (30.5%) had positive CRP test. The incidence rate of myocardial infarction in the studied population was 14.3% (108 cases). There was significant association between positive CRP and developement of myocardial infarction (P=0/000). The findings also showed linear association between incidence rate of myocardial infarction and degree of positivity of CRP test.
CONCLUSIONS: Our study shows that incidence rate of myocardial infarction is relatively higher in our patients with unstable angina. So, further evaluation to identify it`s related factors is recommended. The findings also suggest that CRP test may have a prognostic value in the patients with unstable angina.

Abstract
Background and aim: Cardiovascular diseases are the main cause of death worldwide. The myocardial performance index (Tei index) is an accepted method for the evaluation of the systolic and diastolic function of the heart. There is not enough data about the association between the Tei index and the severity of unstable angina disease. In this study, we evaluated the association between the Tei index and unstable angina.
Material and methods: The association between the Tei index measured by two different methods (tissue and continuous Doppler) and the severity of coronary artery disease in 170 adult patients was evaluated. The Tei index higher than 0.55 in tissue Doppler and 0.4 in continuous Doppler methods were considered as abnormal. Finally, the association between the Tei index and angiography findings was evaluated.
Results: The mean age of patients was 58.26±10.62 years. The association between Tei index measured by the two methods mentioned above and the severity of coronary artery disease was not significant statistically. (p value=0.67 and 0.072 respectively)
Conclusion: there is no association between the severity of coronary artery disease (1-3 vessel disease) and the Tei index in patients with unstable angina.
