- Healthy Volunteers: f

Study Arms:
- sacubitril/valsartan (LCZ696) (Type: EXPERIMENTAL): All patients who fulfill the inclusion/exclusion criteria will be stratified before randomization based upon prior therapy for comorbidities to one of 3 strata: ACEi, ARB or no RASi. Patients in the ACEi strata will receive LCZ696 or enalapril. Patients in the ARB strata will receive LCZ696 or valsartan. Patients in the no RASi strata will receive LCZ696 or matching placebo.~Patients in the ACEi and ARB strata will take two pills twice daily for each dose: one tablet from the LCZ696 pack and one tablet from the comparator pack. Patients in the no RASi strata will take only one tablet twice daily (LCZ696 or matching placebo).~In the LCZ696 arm, patients will receive active LCZ696 in titrated doses from level 1 up to level 3 (50 mg, 100 mg and 200 mg twice daily orally).
- Comparator (Type: ACTIVE_COMPARATOR): Patients randomized to the comparator arm will receive either enalapril (ACE stratum) valsartan (ARB stratum) or LCZ696 matching placebo (no RASi stratum).~Patients in the ACE stratum randomized to comparator, will receive enalapril in titrated doses from level 1 up to level 3 (2.5 mg, 5 mg and 10 mg twice daily).~Patients in the ARB stratum randomized to comparator will receive valsartan in titrated doses from level 1 up to level 3 (40 mg , 80 mg and 160 mg twice daily).~Patients in the no RASi stratum randomized to comparator will receive LCZ696 matching placebo.
