Primary prevention of stroke: blood pressure, lipids, and heart failure

Area of Science:

• Neurology
• Cardiology
• Public Health

Background:

• Stroke is a leading cause of global morbidity, mortality, and disability.
• Acute treatments and rehabilitation have advanced, but primary prevention is essential to manage the global burden.
• Stroke risk factors differ from coronary heart disease, necessitating specific preventive strategies.

Purpose of the Study:

• To review evidence on stroke risk factors and primary prevention strategies.
• To highlight the prominent role of elevated blood pressure (BP) and heart disease in stroke risk.
• To discuss current and novel approaches for the primary prevention of stroke.

Main Methods:

• Review of epidemiological studies and clinical evidence on stroke risk factors.
• Analysis of the contribution of individual risk factors to stroke occurrence.
• Discussion of lifestyle interventions and pharmacological strategies for primary prevention.

Main Results:

• Elevated blood pressure (BP) and heart disease are significant stroke risk factors.
• The influence of lipids on stroke risk is less clear.
• Stroke is a notable complication of heart failure.
• An estimated 70% of strokes may be preventable through lifestyle modifications, though prospective evidence is needed.

Conclusions:

• Co-ordinated primary prevention strategies are vital to tackle the global burden of stroke.
• Focusing on absolute cardiovascular disease risk, rather than individual factors, is recommended.
• Lifestyle interventions are foundational for primary prevention; drug interventions, including the polypill, warrant consideration.
• Further research and targeted interventions for BP, heart failure, and possibly lipids are needed for effective stroke primary prevention.
