Heart failure (HF) is a major health care burden increasing in prevalence over time. Effective, evidence-based interventions for HF prevention and management are needed to improve patient longevity, symptom control, and quality of life. Dietary Approaches to Stop Hypertension (DASH) diet interventions can have a positive impact for HF patients. However, the absence of a consensus for comprehensive dietary guidelines and for pragmatic evidence limits the ability of health care providers to implement clinical recommendations. The refinement of medical nutrition therapy through precision nutrition approaches has the potential to reduce the burden of HF, improve clinical care, and meet the needs of diverse patients. The aim of this review is to summarize current evidence related to HF dietary recommendations including DASH diet nutritional interventions and to develop initial recommendations for DASH diet implementation in outpatient HF management. Articles involving human studies were obtained using the following search terms: Dietary Approaches to Stop Hypertension (DASH diet), diet pattern, diet, metabolism, and heart failure. Only full-text articles written in English were included in this review. As DASH nutritional interventions have been proposed, limitations of these studies are the small sample size and non-randomization of interventions, leading to less reliable evidence. Randomized controlled interventions are needed to offer definitive evidence related to the use of the DASH diet in HF management.
心力衰竭（HF）是一种主要的医疗保健负担，随着时间的推移其患病率不断增加。需要有效的、基于证据的干预措施来预防和管理 HF，以提高患者的寿命、症状控制和生活质量。 膳食方法防治高血压（DASH）饮食干预措施对 HF 患者可能有积极影响。然而，由于缺乏全面的饮食指南和实用证据，限制了医疗保健提供者实施临床建议的能力。通过精准营养方法来完善医学营养治疗有可能减轻 HF 的负担、改善临床护理，并满足不同患者的需求。本综述的目的是总结与 HF 饮食建议相关的现有证据，包括 DASH 饮食的营养干预措施，并为 HF 门诊管理中 DASH 饮食的实施制定初步建议。使用以下搜索词获取涉及人类研究的文章：膳食方法防治高血压（DASH 饮食）、饮食模式、饮食、代谢和心力衰竭。本综述仅纳入了全文为英文的文章。由于已经提出了 DASH 营养干预措施，这些研究的局限性在于干预措施的样本量小且非随机，导致证据不太可靠。需要进行随机对照干预研究，以提供有关 DASH 饮食在 HF 管理中应用的明确证据。
