Treatment of post-stroke hypertension. A practical guide

Area of Science:

• Neurology
• Cardiology
• Internal Medicine

Background:

• Cerebrovascular disease is a major cause of death and disability, particularly in older adults.
• Hypertension is a key risk factor for stroke, with 80% of acute stroke patients exhibiting high blood pressure upon admission.
• The role and management of hypertension following a stroke remain unclear and debated.

Purpose of the Study:

• To review current evidence on the risks and benefits of treating post-stroke hypertension.
• To describe the pathophysiology of post-stroke hypertension, focusing on cerebral blood flow autoregulation.
• To provide guidance on the management of post-stroke hypertension in the absence of definitive clinical trial data.

Main Methods:

• Review of existing literature and expert opinion on post-stroke hypertension management.
• Discussion of the pathophysiology of cerebral blood flow regulation after stroke.
• Analysis of current recommendations for blood pressure management in acute stroke patients.

Main Results:

• Immediate blood pressure reduction post-stroke is generally recommended only in specific critical situations like hypertensive encephalopathy or aortic dissection.
• There is a lack of comparative data on different antihypertensive agents for acute stroke.
• Short-acting vasodilators are suggested if pharmacological intervention is necessary.

Conclusions:

• The clinical significance and optimal management of post-stroke hypertension are not well-established.
• Current recommendations for early treatment are based on expert consensus for specific indications.
• Ongoing clinical trials are expected to offer clearer guidelines for secondary stroke prevention through blood pressure management.
