Assessment
Primary outcomes The primary endpoint was percent change (%Change) from baseline to week 24 in plasma A-, B-, and N-terminal pro-B-type natriuretic peptide (ANP, BNP, and NT-proBNP) levels.
Key secondary outcomes The second endpoint was the change in echocardiographic parameters related to myocardial remodeling from the baseline to week 24.

Number of participants that the trial has enrolled 11
Results The %Change in ANP and NT-proBNP levels was significantly greater in the ARB-switch group than that in the ARNI-continue group,
wheras that in BNP levels was not significantly different between the ARNI-continue and ARB-switch group.

In the ARB-switch group, there was a
significant increase from the baseline to week 24 in left ventricular (LV) end-systolic volume (p = 0.043) and LV peak-systolic wall stress (p = 0.012), and a trend toward a decrease in LV ejection fraction (p = 0.080).

Baseline Characteristics The patient age of the ARB-switch group was significantly smaller than that of the ARNI-continue group (p = 0.028). No significant differences in sex, body mass index, body surface area, heart rate, BP, risk factors, biochemical data, and medications were not found between the two groups.
Participant flow Despite the recommendation to continue the ARNI treatment, six of 11 patients desired the change from the treatment with ARNI to that with ARB because of medical costs or two weeks visit after the study. The remaining five patients wanted to continue the treatment with ARNI. After completed the core study between December 2020 and January 2021, two groups were enrolled in this study: five patients who requested the continuous treatment with ARNI: sacubitril valsartan of 400 mg/day (ARNI continue group);and six patients who requested the treatment with ARB: valsartan of 160 mg/day (ARB switch group).
Adverse events In all patients, the ARNI or ARB treatment was not changed or discontinued during the study period. No patients were given additional medications for HF such as sodium-glucose cotransporter-2 inhibitors. Unplanned hospitalization due to worsening HF or other cardiovascular events was not observed in the both groups.
Outcome measures Switching from ARNI to ARB may worsen HF due to returning to myocardial remodeling induced by a sustained decline in ANP levels.
