Risk factors for coronary disease: the time for a paradigm shift?

Area of Science:

• Cardiology
• Biochemistry
• Preventive Medicine

Background:

• Traditional cardiovascular risk assessment relies on factors like age, smoking, hypertension, diabetes, and cholesterol levels.
• Existing algorithms inadequately identify individuals at risk, as many low-risk individuals still experience cardiac events.
• Disturbed lipid metabolism, particularly fuel transport pathways, may play a significant role in atherogenesis.

Purpose of the Study:

• To explore current challenges in cardiovascular risk assessment.
• To introduce the concept of lipid fuel transport and overflow pathways in atherogenesis.
• To evaluate novel risk factors and their integration with existing methods for comprehensive risk stratification.

Main Methods:

• Review of current cardiovascular risk assessment algorithms and their limitations.
• Discussion of lipid metabolism pathways, including chylomicron, VLDL, and LDL.
• Consideration of novel biomarkers such as C-reactive protein, plasma fibrinogen, and cardiac troponins (I and T).

Main Results:

• Traditional risk factors are insufficient for accurate prediction of cardiac events in all individuals.
• Lipid transport and overflow pathways represent a critical, yet under-monitored, aspect of atherogenesis.
• Serum C-reactive protein and plasma fibrinogen are identified as valuable additions to cardiovascular risk profiles.
• Cardiac troponin levels indicate acute myocardial damage, complementing risk factor assessment.

Conclusions:

• Integrating novel cardiovascular risk factors (lipid metabolism, inflammation) with traditional factors enhances risk stratification.
• Combining markers of acute myocardial damage with new risk factors represents the future direction for accurate cardiovascular risk assessment.
• Improved risk stratification strategies are crucial for effective primary and secondary prevention of cardiovascular disease.
