ACE and heart failure: Whilst the rates of prescribing disease modifying agents in patients admitted to hospital with heart failure have improved over the last decade, recent registries conducted in Europe, the Asia-Pacific region, and the USA still report discharge prescription rates of 63–80% for ACE inhibitors or angiotensin receptor blockers, 41–74% for beta blockers, and 20–48% for aldosterone antagonists [97, 98, 115, 122].
