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 review discusses the studies that have investigated the effect of cardiac rehabilitation programs on people with Covid-19.
Background. It has been previously revealed the profits of cardiac rehabilitation for patients who suffer from cardiovascular diseases. With the occurrence of the covid-19 pandemic, many have suffered from cardiovascular complications due to the coronavirus infection. Despite the application of many medications and therapeutic interventions to control the side effects, many are still experiencing the secondary complications of the disease, specifically the cardiovascular complications, and the search for an effective solution continues. The use of cardiac rehabilitation for these patients may be effective.
Method. A broad search was conducted in scientific databases and search engines such as Science Direct, PubMed, Cochrane, Medline, SID, Scopus, CINAHL, OVID, Iran Doc, and Magiran with the keyboards “Covid-19”, “post covid-19 period”, “cardiac rehabilitation” and “rehabilitation” in both English and Persian language journals published between 2000 and 2022. After a comprehensive review, nine studies that met the purpose of this study were selected.
Findings. Cardiac rehabilitation programs decrease complications, mortality, and readmission of people with Covid-19, and modify the signs, physical and cardiovascular functions, and the quality of life in these patients.
Conclusion. For finer efficacy of cardiac rehabilitation programs, designating a program suited for the patient's condition, schedule adherence, and evaluation of the findings should be considered. It seems that cardiac rehabilitation programs can be beneficial for people with Covid-19 in reducing complications and mortality rates. More studies are needed for more information.
