Contribution of individual risk factor changes to reductions in population absolute cardiovascular risk

Area of Science:

• Cardiology
• Public Health
• Preventive Medicine

Background:

• Limited research exists on individual risk factor contributions to absolute cardiovascular disease (CVD) risk.
• Fewer studies examine how changes in individual risk factors impact overall modifiable risk after CVD prevention interventions.

Purpose of the Study:

• To evaluate individual risk factor contributions to absolute CVD risk in high-risk patients.
• To estimate the proportion of modifiable risk reduction attributable to each factor post-intervention.

Main Methods:

• Longitudinal study analyzing CVD risk factor changes in patients undergoing a health screening and enhanced support program.
• Assessed absolute CVD risk and the modifiable risk removed by individual factors after one year.

Main Results:

• High cholesterol (57%), smoking (53%), and high blood pressure (26%) were most prevalent. Smoking contributed most to modifiable CVD risk (57%), followed by high blood pressure (26%) and high cholesterol (17%).
• After one year, the intervention removed substantial modifiable risk: smoking (56%), high blood pressure (68%), and high cholesterol (53%).

Conclusions:

• The intervention successfully removed approximately 59% of modifiable risk associated with high blood pressure, high cholesterol, and smoking.
• This highlights the effectiveness of targeted interventions in mitigating multiple cardiovascular risk factors simultaneously.
