Abstract
Aim. The present study was conducted to determine the relationship between seasonal changes and incidence of AMI in Sistan and Baluchestan province, Iran.
Background. Although various studies have been carried out to examine the relationship between seasonal changes and incidence of Acute Myocardial Infarction (AMI) in different parts of the world, many of them have limitations and there are many contradictions between their findings. Despite considerable prevalence of AMI in Sistan and Baluchestan Province, similar studies have not been conducted in this area.
Method. This cross-sectional study was done based on medical data of heart center of Sistan and Baluchestan Province from March 2015 to April 2016. In this study, census sampling was achieved of all the patients with AMI symptoms. Variables such as age, sex, marital status, birth date, physical symptoms, and past medical history; and also meteorological parameters such as minimum, maximum and average of temperature (Celsius), and wind direction were collected.
Findings. Except of mean rainfall, mean rate of other parameters had statistically significant differences during 12-month period of the study. Spearman correlation test showed a positive statistically significant correlation of incidence of AMI during one year with sunshine hours (r=0.685, p=0.014), and maximum daily temperature (r=0.626, p=0.030).
Conclusion. Finding revealed that raising temperature had direct relationship with incidence of AMI. The findings could be a foundation for governmental important health plans to control the incidence of AMI.

Abstract
Aim. The aim of this study was to review the effect of music as a non-invasive, non-pharmacological, inexpensive method with no side effects, on people with heart disease
Background. Heart disease is a common disease with considerable annual mortality. This review study investigates studies to bring a comprehensive view about the effect of music therapy on recovery of people with heart disease.
Method. This study was a narrative review in which studies in Persian and English language were searched out in databases/ search engines Magiran, SID, IranMedex, Pubmed, Scopus, and Google Scholar using the keywords music therapy, heart failure, acute coronary syndrome, hypertension, hypertension, heart surgery and open heart surgery. Inclusion criteria included articles being published in Persian or English language that examined the effect of music on recovery of people with heart disease. There was no time limit for articles under review. Exclusion criteria included articles that their full text were not accessible.
Findings. Out of 24 articles, the most of them (10 articles) examined the effect of music on hypertensive patients and on vital signs in heart patients (8 articles). The results showed that the effect of music on the recovery of heart patients included increasing the percentage of oxyhemoglobin saturation, relieving pain, reducing anxiety and depression, improving sleep quality and reducing fatigue. The music had no effect on mean arterial pressure and respiration. There were conflicting results regarding the effect of music on blood pressure and heart rate.
Conclusion. Considering the easy and cost-free application of this method, it is recommended that the health care team and especially nurses use this non-invasive method in the care of people with heart disease.

Abstract
Aim. This literature review was conducted to investigate determinants of readmission among Iranian people with heart failure.
Background. Heart failure (HF) as a chronic progressive syndrome may reduce the quality of life and increase their treatment costs. The rate of readmission is relatively high in these patients, presenting a major health problem.
Method. In the present literature review, the literature on the topic were searched out in databases PubMed, Google Scholar, Web of Science, ProQuest, Magiran, SID, and IranMedex. The terms heart failure, congestive heart failure, readmission, rehospitalization, and Iran were searched without time limit. Literature search and evaluating the articles were independently conducted by two researchers, and all eligible studies were included in the review process.
Findings. Out of 601 studies found in the initial search, seven articles meeting the inclusion criteria entered the final phase of the study and were reviewed. According to these studies, the readmission rate varied from 10.9 to 40 percent. Some of the important factors affecting the readmission rate in patients with heart failure included age, gender, education, job status, underlying disease, disease stage, poor adherence to the therapeutic regimen, insurance coverage status, and place of residence.
Conclusion. Based on the results of the present study, the rate of readmission was high among Iranian patients with heart failure. It is recommended to consider interventions such as educational programs to improve patients’ awareness about this condition and their adherence to self-care activities.

Abstract
Aim. The aim of this study was to examine the effect of telemonitoring on the compliance with self-care recommendations in patients with heart failure.
Background. Patients with heart failure need to strengthen their self-care behaviors in order to cope with the problems caused by the disease. This is despite the fact that most patients have poor compliance with self-care recommendations. In recent years, telemonitoring has been considered as an effective approach to increase patients compliance with self-care recommendations.
Method. This was a quasi-experimental study with an intervention group. The desired outcome was adherence to weekly self-reporting of three subjects: vital signs, questions related to experienced symptoms related to the disease and questions related to educational content. The statistical sample consisted of 68 people with heart failure referred to the heart failure clinic of selected hospitals in Tehran, Iran, who were selected by available methods and were trained and followed up for 8 weeks through messengers and phone calls.
Findings. Out of 68 patients, 7 patients were excluded, and the data of 61 patients was analyzed and reported as percentage of frequency. This method of intervention has received very good feedback from the participants such that the average response to questions related to weekly educational content was 91.9 percent, the average weekly self-reporting of vital signs was 86.4 percent, and the average weekly response to questions related to symptoms experienced related to the disease was 93 percent.
Conclusion. The results show that telemonitoring is effective in increasing the compliance with self-care recommendations in patients with heart failure.
