signs of end organ damage (CVS/ renal)
diabetics
anyone with Qrisk≥ 20%

everyone
what is target BP for those with essential hypertension without end -organ damage?
- ≥ 80 years 150/90 or ABPM 145/85
- <80 years 140/90 or ABPM 138/85

what is the function of ACEi?
- Inhibit conversion of angiotensin I into II
- Reduce release of aldosterone (aldosterone causes fluid and water retention – stimulates reabsorption of salt and water in the kidneys)
- aid in arterial and left ventricular remodelling
