Research articles in Persian and English focusing on the factors affecting the adherence to treatment in cardiovascular patients were selected for the study. In total, 167 articles were found in primary search by reviewing the title and abstract and in some cases after studying the full text of the articles; out of them, 11 were selected that were in accordance with the research purpose of this study.
Findings. The most effective methods for improving adherence to treatment were tele-nursing and educating colleagues on how to follow up patients. Also, recognizing differences between personal and psychological aspects of patients and adopting an appropriate method for each person to pursue treatment and increase adherence to the treatment regimen are very important known factors in the care of cardiovascular patients.
Conclusion. In general, the care and training provided and continuous follow-up by the health care professionals have the greatest impact on increasing adherence to the treatment regimen among patients.
