Confirm resistant hypertension and discuss adherence
Consider seeking expert advice or adding a:

A 60 year old lady has been confirmed to have a BP of 156/95 mm Hg for the last three to four months with no evidence of end organ damage. Her BMI was 31. Her GP gave her some advice to reduce weight and salt in her diet. 3 months later, her BP is 150/91 and BMI hasn’t changed.
What should the next step be?
Continue life style measures and Start ACEI

Consider specialist referral to rule out secondary causes
What is the management of a patient with BP 180/110 but with no evidence of end organ damage?
Manage in primary care
