A Comparative Study of Cardiovascular Risk Calculation Systems and the New PREVENT Model

Area of Science:

• Cardiology
• Preventive Medicine
• Biostatistics

Background:

• Cardiovascular diseases (CVD) represent a significant, yet largely preventable, global cause of mortality.
• Individual CVD risk is influenced by modifiable and non-modifiable factors.
• Established risk assessment tools include Framingham, Reynolds, and the PREVENT system.

Purpose of the Study:

• To compare the cardiovascular disease (CVD) risk scores generated by the Framingham, Reynolds, and PREVENT systems.
• To evaluate the impact of common risk factors on CVD risk scores across these three systems.

Main Methods:

• Comparative analysis of CVD risk scores from Framingham, Reynolds, and PREVENT.
• Identification of shared risk factors: age, gender, smoking status, HDL cholesterol, total cholesterol, and systolic blood pressure.
• Presentation of comparative risk scores stratified by gender and smoking status.

Main Results:

• The PREVENT system provides more individualized CVD risk assessments.
• PREVENT incorporates renal, metabolic, and social markers, alongside age of risk, for a detailed evaluation.
• Observed differences in risk scoring across the three systems.

Conclusions:

• The PREVENT system's comprehensive approach may enhance the accurate classification of both low- and high-risk patients.
• Improved patient stratification can facilitate tailored interventions and treatments, potentially altering the trajectory of cardiovascular disease.
• PREVENT's detailed assessment may lead to more effective CVD management strategies.
