Triglyceride as a risk factor for coronary artery disease

Area of Science:

• Cardiology
• Lipid Metabolism
• Preventive Medicine

Background:

• The independent association between triglyceride levels and coronary artery disease (CAD) risk is less clear than that of LDL and HDL cholesterol.
• Triglycerides may act as a synergistic risk factor, particularly in the 'lipid triad' (high LDL, low HDL, high triglycerides).
• Heterogeneity of triglyceride-rich lipoproteins complicates their direct correlation with CAD risk.

Purpose of the Study:

• To evaluate the role of triglyceride concentrations in coronary artery disease (CAD) risk.
• To discuss the assessment and management of hypertriglyceridemia in the context of CAD.
• To explore the effectiveness of various lipid-lowering therapies.

Main Methods:

• Analysis of existing data on triglyceride concentrations and CAD risk.
• Review of evidence for triglycerides as independent and synergistic risk factors.
• Assessment of current methods for evaluating hypertriglyceridemia.
• Discussion of nonpharmacologic and pharmacologic management strategies.

Main Results:

• Triglyceride's independent role in CAD risk is debated, but it's a significant synergistic factor.
• The 'lipid triad' is associated with substantial risk reduction from lipid-lowering therapy.
• Fasting triglyceride levels and combined lipid profiles are practical assessment tools.
• Pharmacologic options like fibrates, niacin, and statins offer therapeutic benefits.

Conclusions:

• Hypertriglyceridemia is an important consideration in assessing global CAD risk.
• Management should prioritize lifestyle modifications, with pharmacologic interventions as needed.
• Combination therapy may be necessary for optimal lipid management in high-risk patients.
