Participants will be randomized to two treatment arms in a 1:1, double blinded fashion. Two strengths of sacubitril/valsartan will be available for use after randomization, 49 mg sacubitril/51 mg valsartan and 97 mg sacubitril/103 mg valsartan. After randomization, subjects in this arm will receive sacubitril/valsartan 100 mg orally twice daily (BID). The dose will be then up-titrated to 200 mg BID (or maintained at the starting dose level, if up-titration is not possible). Dose modifications are allowed until week 4 after the randomization. In order to be eligible for the final assessments, the subject has to tolerate the 100 mg BID dose at the minimum. In total, participants will be on sacubitril/valsartan for a minimum of 8 weeks and a maximum of 10 weeks.
sacubitril/valsatran 100 or 200 mg BID
Drug: placebo to valsartan
placebo to valsartan 80 or 160 BID
Active Comparator: valsartan
Participants will be randomized to two treatment arms in a 1:1, double blinded fashion. In this arm, Valsartan 80 mg and 160 mg will be used as comparative drug, taken orally BID at home. Depending on the screening/run-in dose the subjects in this arm will get either valsartan 80 mg BID or valsartan 160 mg BID. During the treatment period the dose of valsartan will be up-titrated to the highest tolerated dose (160 mg BID) or maintained at 80 mg BID if up-titration is not possible. Dose modifications are allowed until week 4 after the randomization. In order to be eligible for the final assessments, the subject has to tolerate at least 80 mg BID dose of valsartan. The treatment phase will be a minimum of 8 weeks, and a maximum of 10 weeks.

- Change from baseline in cardiac oxygen consumption and efficiency of cardiac work [ Time Frame: baseline, at week 6 ]Change from baseline in cardiac oxygen consumption and efficiency of cardiac work after 6 weeks of stable sacubitril/valsartan therapy compared to that of in patients on valsartan therapy using 11C-acetate positron emission tomography (PET).
