Measure accurately
Device validation, appropriate cuff size, positioning, rest and repeated measurements affect classification; out-of-office values can clarify the picture.
Assess possible causes
Most adults have primary hypertension; kidney, endocrine, vascular, medication and sleep-related factors can contribute to secondary causes.
Evaluate total risk
Clinical assessment considers cardiovascular disease, kidney function, diabetes and evidence of end-organ injury alongside blood pressure itself.
