Investigating secondary hypertension in cerebrovascular disease

Abstract

Hypertension is the leading cause of stroke in the UK and worldwide. In recent years, stroke incidence has increased by 30%-41.5% in people aged under 64 years, with the prevalence of hypertension increasing by 4%-11%. Given that 5%-10% of people with hypertension in the general population have an underlying cause for their elevated blood pressure, it is important that all clinicians should maintain a high clinical suspicion for secondary hypertension. This review provides a clinical perspective of when to consider the underlying causes of secondary hypertension, with investigation algorithms for patients presenting with stroke and hypertension. Early involvement of hypertension specialist services is important to identify secondary causes of hypertension, as its effective control reduces cardiovascular-associated morbidity.
