Large outcome studies demonstrated a reduction of heart failure hospitalization or cardiovascular death in patients with chronic heart failure (CHF). The renin–angiotensin system (RAS) is a key player in fluid and sodium regulation. The classic angiotensin‐converting enzyme–angiotensin II–angiotensin‐1 receptor axis (Ang I–ACE–Ang II receptor axis) is predominantly angiotensin II (Ang‐II) induced and promotes vasoconstriction. In contrast, the angiotensin‐converting‐enzyme‐2–angiotensin‐(1‐7)–Mas axis (Mas‐axis) is mediated by the metabolites angiotensin‐1‐7 (Ang‐(1‐7)) and angtiotensin‐1‐5 (Ang‐(1‐5)) and exerts cardioprotective effects.
