Introduction: This study aimed to investigate the effect of eight weeks of interval training on gene expression of Ryanodine receptors' calcium channels and calcium pump in ischemic rats.Methodology: 28 Wistar male rats (200-250 g) were used in this study. They were randomly divided into 4 groups: Sham, Ischemia, Exercise, and Exercise-ischemia. Myocardial infarction (MI) was done by closing the descending coronary artery (LAD) for 30 minutes. Exercise program on treadmill was for 8 weeks, 3 days a week for 40 minutes. The rats were anesthetized and the heart tissue was isolated 48 hours after the last training session and injections. SERCA2a and RyR2 gene expression was measured for heart tissue cells. Results: The results showed that SERCA2a gene expression level was increased in both groups of exercise and exercise-ischemia (p= 0.001) and this increase was significantly higher in exercise-ischemia group (p = 0.001). Also, the results showed that 8 weeks of interval training significantly increased RyR2 gene expression level in two groups of exercise- ischemia and exercise. But a significant decrease was observed in RyR2 gene expression level in ischemia group. Discussion and Conclusion: This study results show that a regular interval training program eliminates abnormal contractions associated with cardiomyopathy due to myocardial ischemia and rehabilitates cardiac muscle calcium control and increases mainly the contraction strength by the increase of left ventricle mass.

Background & Objectives:Myocardial infarction is one of the main causes of death and disability in the world. Adherence of therapeutic regimen is an important caring option in these patients. This study has been conducted to determine the effect of family-centered education on laboratory index of patients after acute myocardial infarction. Materials & Methods: This clinical trial was performed between October and March 2014 in CCUward of Amirkabir hospital of Arak. Research samples were 60 patients with 30-70 years old who had been selected by convenience method after the first heart attack and randomly assigned into two groups: control (patient-centered education: 30 individuals) and intervention (family-centered education: 30 individuals). On admission, blood sugar and blood lipids (Chol, TG, HDL, LDL) were examined. Theneducation to patients was done in the intervention group associated with close family member through computers in three domains (diet, pharmaceutical regimen and exercise program) in three sessions of 30-45 minutes and the same educational content were taught to the patient (without family members) in the control group. Three months after the intervention, all aforementioned items were recorded again in two groups and, finally, data were analyzed using independent t-test and Chi-square test. Results: The results indicated that laboratory indexincluding blood sugar (P=0.03), blood lipids (P=0.0001) in the family-centered group was better than patient-centered group. However, there was not a significant difference between the two groups in aforementioned items before the intervention (P> 0.05). Conclusion: According to the findings of this study, it seems that family-centered education model improves laboratory index of the patients with myocardial infarction. It is recommended that the educational interventions for the patients with myocardial infarction to be done with the participation of the family.

Introduction: when Patients with myocardial infarction are admitted to intensive care unite, they almost always would be anxious. Anxiety increases the risk of ischemia after myocardial infarction and worsens the prognosis of disease. The aim of this study was to determine the effects of inhaling lavender oil on anxiety levels in myocardial infarction patients admitted to Alzahra Heart Hospital, shiraz.
Materials and Methods: This clinical trial study was conducted on 60 patients with a definite diagnosis of myocardial infarction who were admitted to Alzahra Heart Hospital of Shiraz in 2014. The permuted block randomization method was used. In order to this, Patients were allocated into two intervention (n=30) and control (n=30) groups randomly. In intervention group, participated inhaled the essential oil of Lavender via a non absorbent paper stained with three drops of lavender oil for three times a day and 20-30 minutes every once during three days. In another group, distilled water was used instead of lavender oil in the same way. The data were analyzed using SPSS software version 11/5 with Chi-square, paired t test, and Analysis of Covariance in a significance level of .95%.
Results: in the case group, the average of state and trait anxiety level before of intervention was 60/56±9/29 and 55/73±10/22, respectively decreasing to 41/56±7/57 and 44/53±7/28 after intervention. The average of state and trait anxiety level in control group were 56/60±10/14 and 54/13±9/17 respectively that increased to 63/30±5/19 and 59/96±7/07 in the end of the study. Statistically, the paired t test showed a significant difference in the level of anxiety before and after intervention between both groups (p

Background and Aim: Cardiovascular diseases are major factor in reducing the amount of sleep and increased nighttime wakefulness. Due to the many complications resulting from medication, non-pharmacological methods that can improve the quality of sleep in patients with chronic heart disease, seems to be reasonable. This study aimed to assess the effect of the Benson relaxation technique on quality of sleep in patients with chronic heart disease.
Materials and Methods: The study design is a randomized clinical trial. The study population comprised 60 patients with chronic heart disease referring to Vasei hospital in Sabzevar that randomly divided into control group (n =30) and intervention group (n =30). The intervention Group did Benson relaxation exercises for 20 minutes twice a day over a month. Tools for data collection Consists of; demographic form and Pittsburgh Sleep Quality Index that in two times before and after the intervention were completed. Data with Mann-Whitney test, Chi-square, Fisher exact, Wilcoxon tests and Analysis of Covariance and using SPSS statistical software version 11.5 and with significance level p˂0/05 were analyzed.
Results: The mean± SD quality of sleep in the intervention group before making a gentle Benson relaxation was; 10/33±4/41 that after the intervention was decreased to 7/5±4/01. Analysis of the data in average sleep quality of participants in the intervention group before and after the intervention showed significant differences (P< 0/001).
Conclusion: Benson relaxation has desired effect on sleep quality of patients with chronic heart diseases, so it can be used as a complementary therapy to improve sleep quality in these patients.

Background: Given the high prevalence and high mortality of cardiovascular disease, special attention should be paid to its treatment. Currently, the main treatment for ST-elevation myocardial infarction is restoring blood flow by dissolving the clot. In addition to this basic treatment, several pharmacologic agents have been studied during the past years. In this paper, clinical trials about glucose-insulin-potassium are discussed in addition to adjuvant treatment which has been suggested in recent years. Materials and Methods: All studies published in journals or presented at scientific conferences were searched in Elsevier, PubMed, Cochrane, and SID databases using relevant keywords. After quality control, eligible articles were included in the study. Results: The results of this review article showed that studies on the effects of glucose-insulin-potassium treatment on mortality, cardiac enzyme levels, left ventricular ejection fraction, ST resolution, and inflammatory and oxidative biomarkers have been conflicting. But, generally, evidence from newer studies conducted on larger numbers of patients has shown ineffectiveness of glucose-insulin-potassium therapy. Conclusion: Currently, glucose-insulin-potassium therapy should not be recommended as an adjunct to thrombolytic therapy.
