Heart failure is a group of syndromes caused by various cardiac structural or functional disorders leading to impaired ventricular filling and (or) ejection capacity. Because of decreased ventricular systolic function and impaired ejection function, the amount of cardiac output cannot meet the body’s metabolic needs; organ and tissue blood perfusion is insufficient; at the same time, pulmonary circulation and (or) systemic circulation congestion; the clinical manifestations are mainly dyspnea and weakness but restricted physical activity and edema. Treatment of the disease should include preventing and delaying the onset of wails, relieving symptoms of clinical wails, improving its long‐term prognosis, and reducing mortality. The aim of the study is to observe the efficacy and safety of Entresto in the treatment of left ventricular ejection fraction heart failure (HFpEF). Seventy‐eight patients with HFpEF treated in our hospital from October 2017 to April 2018 were randomized into a treatment group (Entresto 50 mg + basic treatment, n = 39) and a control group (basic treatment, n = 39). The course of treatment was ten weeks. The levels of brain natriuretic peptide (BNP) and echocardiographic indicators (LVMI, LVEF, LVEDD, LVESD, E/E′ Ratio, E/A ratio, DT), 6‐minute walking test (6MWD), and Minnesota Quality of Life Scale (MLHFQ) were analyzed before and after treatment. LVMI, LVEF, LVEDD, LVESD, E/E′ ratio, E/A ratio, DT, and BNP were all significantly improved in the Entresto group after treatment. In the control group, except for LVEDD, LVESD, the E/A ratio, and BNP, other indicators were significantly improved after treatment (P < 0.05). Posttreatment, both groups had significantly improved 6MWD and MLHFQ scores (P < 0.05). Differences in these parameters between the two groups were statistically significant (P < 0.05). After treatment, the levels of NE, AngII, ALD, and MMP‐9 in the two groups were decreased (P < 0.05), with the lower lever in the treatment group (P < 0.05). The effective rate was 76.92% in the control group and 94.87% in the Entresto group, and this rate difference was statistically significant (P < 0.05). The number of patients re‐hospitalized due to cardiovascular events was 2 (the Entresto group) vs. 7 (the control group) cases; worsening of heart failure was observed in 1 patient (the Entresto group) vs. 6 (the control group), and the difference between the two groups was statistically significant (P < 0.05). However, the incidence of adverse reactions between the two groups was not statistically significant. Entresto can significantly improve left ventricular diastolic function in heart failure patients with preserved left ventricular ejection fraction and improve quality of life. This treatment is safe and effective and worthy of clinical application. This trail is registered with ChiCTR2000031486.
