Abstract Aims Although the haemodynamic effects of angiotensin receptor‐neprilysin inhibitor (ARNI) on patients with heart failure have been demonstrated, the effect on glucose metabolism has not been fully elucidated. We retrospectively investigated the effect of ARNI on abnormal glucose metabolism in patients with stable chronic heart failure using an additional structural equation model (SEM) analysis. Methods We analysed 34 patients who regularly visited to the outpatient department of our institute with heart failure from October 2021 and July 2022 and who were taking angiotensin‐converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs). Seventeen patients switched from ACE inhibitors or ARBs to an ARNI (ARNI group), and the other 17 patients continued treatment with ACE inhibitors or ARBs (control group). Results At baseline, although the ARNI group included fewer patients with heart failure with preserved ejection fraction in comparison with the control group (P = 0.004), patients with heart failure with mildly reduced ejection fraction, and heart failure with reduced ejection fraction were mostly biased towards the ARNI group (although not statistically significant). The baseline insulin resistance in the ARNI group was already significantly higher in comparison with the control group [fasting blood insulin, 9.7 (7.4, 11.6) vs. 7.8 (5.2, 9.2) μU/mL, P = 0.033; homoeostasis model assessment of insulin resistance (HOMA‐IR), 3.10 (1.95, 4.19) vs. 2.02 (1.56, 2.42), P = 0.014]. Three months later, the fasting blood insulin and the HOMA‐IR levels were both found to have decreased in comparison with the baseline values [baseline to 3 months: insulin, 9.7 (7.4, 11.6) to 7.3 (4.6, 9.4) μU/mL, P < 0.001; HOMA‐IR, 3.10 (1.95, 4.19) to 1.96 (1.23, 3.09), P < 0.001]. An additional SEM analysis demonstrated that the initiation of ARNI had caused a reduction in the fasting blood insulin and the HOMA‐IR levels at 3 months independently of the baseline fasting blood insulin and HOMA‐IR levels, respectively. Similarly, the initiation of ARNI resulted in a significant reduction in serum uric acid levels (6.28 ± 0.35 to 5.80 ± 0.30 mg/dL, P = 0.008). Conclusions In conclusion, even in a short period of only 3 months, the administration of ARNI improved insulin resistance and consequently reduced the serum uric acid levels in patients with stable chronic heart failure. Although the ARNI group already had high insulin resistance at baseline, an additional SEM analysis revealed that the decreased insulin resistance was truly due to the effect of ARNI.
