Global cardiovascular risk assessment tools vary significantly, impacting treatment decisions for primary prevention of cerebro-cardiovascular diseases. Different risk calculators yield diverse results, influencing interventions and healthcare costs.

Area of Science:

  • Cardiology
  • Preventive Medicine
  • Health Economics

Background:

  • Global cardiovascular risk assessment is crucial for primary prevention of cerebro-cardiovascular diseases.
  • Risk stratification for individuals without prior history guides intervention intensity, but significant variability exists.
  • National guidelines, like Italy's, link statin reimbursement to specific risk thresholds (e.g., >20%).

Purpose of the Study:

  • To investigate the variability of cardiovascular risk calculators.
  • To assess the impact of different risk calculators on patient stratification and potential interventions.
  • To estimate the economic implications of using diverse risk assessment tools.

Main Methods:

  • Conducted a comprehensive literature and web review to identify available cardiovascular risk calculators.

  • Performed a simulation study applying multiple calculators to identical patient profiles.
  • Analyzed the discrepancies in risk scores generated by different tools.

    • Main Results:

    • A wide array of cardiovascular risk calculators were identified, exhibiting substantial differences.
    • Simulation demonstrated that applying various calculators to the same individual can produce significantly divergent risk assessments.
    • These discrepancies have notable economic consequences, particularly concerning medication reimbursement.

    Conclusions:

    • The heterogeneity among cardiovascular risk calculators poses challenges for consistent clinical decision-making.
    • Standardization or clear guidance on calculator selection is needed to ensure equitable and effective primary prevention strategies.
    • Addressing calculator variability is essential for optimizing healthcare resource allocation and patient management.
