A 56-year-old man attends his GP in suburban Melbourne for review of elevated blood pressure noted at a pharmacy. Over three separate visits his seated BP measurements are 152/94 mmHg, 148/92 mmHg and 150/96 mmHg. He is a non-smoker with total cholesterol 6.0 mmol/L, HDL 1.0 mmol/L, no diabetes and an absolute 5-year CVD risk calculated at 13%. What is the most appropriate next step in management?
