Abstract
Background : Coronary and artery diseases are amongst the most common existed diseases in human societies. Thus considering too much stress that is created after myocardial infarction and the effect which anxiety can have on the treatment process of
myocardial infraction patients, This research was carried out to study the effect of applying progressive muscle relaxation of these patients.
Materials and Methods: This clinical trail study was done on sixteen patients with myocardial infarction afflicted to the disease two weeks before the beginning of the research.After selecting qualified samples , the patients were divided into two groups of intervention and control. Both groups were matched from view points of age, sex, and the amount of anxiety. In the first day, for each group the cattle anxiety questionnaire was completed and their vital signs were recorded, and then for the intervention group the progressive muscle relaxation technique was done during 3 sequential days and on the whole in 6 sessions. And again after 3days variables were measured. The gathered data were analyzed by SPSS software.
Results: In the intervention group anxiety, systolic and diastolic blood pressure had a significant decrease comparing to the control group (P<0.001),while decrease was not significant in the control group.
Conclusion: progressive muscle relaxation can reduce the amount of anxiety, and systolic and diastolic blood pressure of the patients with myocardial infarction hospitalized in CCU ward, therefore it can play an effective role as a supplement non-medicinal, simple and cheap treatment for these patients

Abstract
Background : In many patients with chest pain, the correct diagnosis of acute myocardial infarction(AMI) is dependent mainly on the measurement of cardiac markers such as cardiac creatin kinase isoenzyme (CK-MB) and cardiac troponin I (cTnI) ,because the electrocardiogram is often non-diagnostic. The measurement of cardiac markers are superior for the detection of minor myocardial injury and more-accurative diagnosis. The purpose of this study was to evaluate the assay of routin method of CK-MB and cTnI in comparison with rapid test method in suspected patients to AMI.
Materials and Methods: The study population comprised 142 patients admitted to the emergency ward with acute chest pain for less than 12 hours before admission. Venous blood specimen were obtained to measure CK-MB and cTnI rapid assay tests with Acon and Golden kits, and Elisa cTnI and photometry CK-MB assays.
Results: The results of Elisa cTnI assay had 52 positive and 90 negative patients compared to Golden cTnI rapid test, 27 positive and 110 negative patients, while in comparison with Acon cTnI rapid test there were 30 positive and 112 negative patients ( p≤ 0.001). The results of photometry CK-MB assay had 39 positive and 103 negative patients compared to Golden CK-MB rapid test which had 60 positive and 77 negative patients( p ≤ 0.001), while in comparison with Acon CK-MB rapid test in had 78 positive and 64 negative patients ( p ≤ 0.035). Relative sensitivity and relative specificity were compared to routne metohs: for the Golden rapid cTnI test were 50% and 98.8% respectively for Acon rapid cTnI test 51.9% and 96.6%, for Golden rapid CK-MB test 69.2%/ and 63.1°/o, and for Acon rapid CK-MB test 69.2% and 50.4% .
Conclusion: The present results showed that the rapid cTnI test is very specific but not sensitive for AMI diagnosis while rapid CK-MB test is neither sensitive nor specific for AMI dignosis in patients with acute chest pain.

Abstract
In recent decades, exercise activity has been the key contributor in controlling many diseases. This review highlights the recent longitudinal studies and randomized clinical trials evaluating the impact of resistance training on the left ventricle structural and functional characteristics. The studies include diverse ethnic populations, including men and women, as well as several (e.g. adults, middle-aged and older adults) age groups. Databases such as PubMed, Medline, Irandoc, SID, Google Scholar, and Magiran were searched for the purpose of this review. After checking 150 abstracts, we reviewed 83 relevant articles to be discussed. Based on the results of the studies, resistance training induces structural and functional changes in the left ventricle commensurate with gene changes providing the basis for improving the efficiency of cardiac function. Therefore, the present study supports the view that resistance training, with special considerations, can be recommended to patients with chronic heart failure who suffer from cardiac events as a preventive solution.

Abstract
Background: The aim of the present study was to investigate the effect of exercise pre-conditioning with intense intermittent exercise on MDA, SOD and GPx enzymes of myocardial infarction following acute myocardial infarction in male rats.
Materials and Methods: Based on this goal, 20 8-week-old male Wistar rats (mean weight 224.41 ± 5.1 g) were divided into 4 groups: control, training, stroke and stroke-training. The training groups performed two weeks of intense intermittent training in four sections. The first part of three days of training, two sessions per day and each session consisting of 4 intense two-minute intervals at a speed of 35 to 40 meters per minute . In the second part, two training days, two training sessions each day containing 4 cycles of intense activity of 2 minutes and 3 cycles of active rest of 2 minutes. The third part, in three training days, included 5 intense cycles and 4 active rest cycles. The fourth part consisted of two training days with the same intensity as the third part but with an increase in the frequency of activity and active rest in each session.
Results: One-way analysis of variance test showed that two weeks of intense intermittent training, although reducing the heart attack area of rats, however, it did not cause significant changes in MDA, SOD and GPx enzymes following acute myocardial infarction between stroke-exercise and stroke groups.
Conclusion: Intense intermittent exercise reduces heart damage in myocardial infarction, and this reduction occurs independently of changes in oxidative and antioxidant factors.
