Methods This study typed keywords (congestive heart failure, adherence, compliance, low sodium diet, low salt diet, dietary sodium restriction) from computer databases (CINAHL, Cochrane, Medline, ProQuest Nursing Allied Health, PubMed, and ScienceDirect) and according to inclusion criteria were as follows: (1) Research objects were adult patients admitted to HF, (2) Research content were related to sodium diet compliance behavior. (3) Non-intervention research. Exclusion criteria were as follows: (1) participants who was pregnant women, (2) qualitative research, (3) studies on development of tool, (4) poster. Select needed 14 articles that meet the purposes of this study. In addition, the study also collected 4 more studies with the same purpose from the references that were included in the retrieved articles, and finally a total of 18 studies were included in the analysis of this study. Data analysis uses descriptive statistics (percentage, frequency distribution) and content analysis method. Results This study use a systematic literature review method, it was found that the results of the studies use nonintervention method, which explored the relevant factors of low-sodium dietary compliance in heart failure patients over the past 20 years, could be summarized in 4 dimensions as social and economic conditions, patient conditions, disease conditions and therapy conditions. Conclusions Heart failure patients’ compliance behavior toward low-sodium dietary is multi-dimensional. Therefore, this study recommends when the health care providers evaluating patients’ compliance behavior of low-sodium dietary, it is necessary to consider more different aspects.
