Ischaemic strokes: management in first six hours

Area of Science:

• Neurology
• Public Health
• Epidemiology

Background:

• Cerebrovascular disease (CVD), or stroke, is a leading cause of morbidity and mortality worldwide, presenting substantial socio-economic challenges.
• The direct and indirect costs associated with stroke treatment and lost productivity are immense, underscoring the global importance of understanding stroke pathophysiology and prevention.
• Hypertension is a primary, treatable risk factor for stroke, with community surveys indicating high prevalence rates, particularly in urban populations.

Purpose of the Study:

• To highlight the global significance of cerebrovascular disease (CVD) and stroke.
• To emphasize the critical role of hypertension as a major modifiable risk factor for stroke.
• To advocate for community-based screening programs for early detection and prevention of stroke.

Main Methods:

• Review of existing literature on stroke pathophysiology and risk factors.
• Analysis of community screening survey data (WHO protocol) for hypertension prevalence.
• Discussion of established stroke prevention strategies, including medication compliance and lifestyle modifications.

Main Results:

• Hypertension is identified as the most significant attributable risk factor for stroke.
• Community screening reveals approximately 15% of urban populations are hypertensive (≥160/95 mm Hg).
• Factors beyond hypertension, such as patient compliance and follow-up, impact stroke mortality reduction.

Conclusions:

• Community screening surveys are essential for early detection of hypertension and transient ischemic attacks (TIAs).
• Primary healthcare centers should serve as hubs for these surveys to ensure representative data for prevention programs.
• Comprehensive stroke prevention requires addressing hypertension, promoting healthy lifestyles, managing associated conditions, and ensuring patient adherence to treatment.
