Abstract: Objective: To systematically review the domestic and foreign research on unmet needs of patients with Chronic Heart Failure (CHF), and thus to provide reference for reducing those unmet needs. Methods: We searched related database from their inception to February 5, 2025. The data-based convergence and integration design was adopted to analyze the unmet needs of patients diagnosed with CHF. Results: A total of 15 studies were included, comprising 1,525 CHF patients. Notably, over 60% of the CHF patients experienced two or more unmet needs post-diagnosis. The final integration results showed 16 unmet needs in CHF patients, referring to physiological needs, activities of daily living, psychological problems, disease-related knowledge and skills defiency, mental problems; economic problems, lack of government support, lack of family support; decreased self-control in life, lack of medical staff support, shared decision-making with medical staff, transitional self-care program learning, discharge preparation, information need, mobile health, exploration of psychosomatic medicine and continuous nursing. Conclusion: Due to the long course and complex conditions of CHF, patients tend to suffer low quality of life. Since there are still many unmet needs that have not been solved, future in-depth researches are needed to construct more targeted CHF nursing intervention programs according to their unmet needs.
