Secondary hypertension in adults

Abstract

Mr Ali, aged 55 years, visited you for a scheduled follow-up for his hypertension, Type 2 diabetes mellitus, ischaemic heart disease and a prior ischaemic stroke. Your first consultation with him was two weeks ago, when he transferred his medical follow-up to your clinic. You reviewed his medications and noted that he is currently taking five antihypertensive medications (hydrochlorothiazide, hydralazine, enalapril, atenolol and amlodipine). His blood pressure during the visit was 154/96 mmHg, while his blood pressure recorded at home was generally about 150/90 mmHg or higher. You reviewed his first set of blood investigations at your clinic and noted that he has hypokalaemia (serum potassium 3.0 mmol/L).
