Heart failure with reduced ejection fraction

Natriuretic peptide system

natriuretic peptides

increase vasodilation

decrease blood pressure

decrease aldosterone

decrease heart hypertrophy

Sacubitril( inhibit enzyme neprilysin) produce inactive fragment

increase bradykinin and angiotensin ll

Renin angiotensin aldosterone system

angiotensin ll

AT2 receptor

increase vasoconstriction

increase blood pressure

increase aldosterone

increase heart hypertrophy

Valsartan( inhibit angiotensin ll)
