European and US guidelines for arterial hypertension: similarities and differences

Area of Science:

• Cardiology
• Public Health
• Clinical Guidelines

Background:

• Hypertension is a prevalent global health issue, contributing significantly to disability and mortality.
• Recent hypertension guidelines from Europe and the United States present divergent approaches to diagnosis and treatment.
• Discrepancies exist in blood pressure classification and treatment targets between European and US guidelines.

Purpose of the Study:

• To analyze and compare the key differences between recent European and US hypertension guidelines.
• To evaluate the implications of these guideline discrepancies on clinical practice and patient outcomes.
• To advocate for a personalized approach in hypertension management, prioritizing a balance between efficacy and safety.

Main Methods:

• Comparative analysis of diagnostic criteria and treatment targets outlined in European and US hypertension guidelines.
• Review of the concept of 'safety boundaries' introduced in European guidelines to prevent overtreatment.
• Appraisal of evidence supporting and opposing controversial issues within the differing guideline recommendations.

Main Results:

• European guidelines define hypertension diagnosis at 140/90 mmHg, while US guidelines use 130/80 mmHg.
• European guidelines incorporate 'safety boundaries' to mitigate risks associated with aggressive blood pressure reduction.
• Significant differences in treatment goals and thresholds necessitate careful consideration in clinical decision-making.

Conclusions:

• The contrasting hypertension guidelines may influence treatment strategies and patient outcomes.
• Rigid blood pressure targets and boundaries may not be universally applicable.
• Personalized hypertension management should focus on achieving an optimal balance between intensive blood pressure reduction and treatment safety for each patient.
