[LDL-cholesterol and cardiovascular events: the lower the better?]

Area of Science:

• Cardiovascular Medicine
• Lipid Metabolism
• Pharmacology

Background:

• Extensive research over 30 years has focused on low-density lipoprotein (LDL) cholesterol's role in cardiovascular disease (CVD) pathogenesis.
• Large-scale statin trials have consistently demonstrated an association between LDL cholesterol levels and cardiovascular event rates, known as the 'LDL cholesterol hypothesis'.

Purpose of the Study:

• To review the evidence supporting the causal relationship between LDL cholesterol levels and cardiovascular outcomes.
• To discuss the implications of this relationship for the individualized treatment of dyslipidemias.

Main Methods:

• Review of findings from major statin trials and recent studies on novel lipid-lowering agents.
• Analysis of the established association and proposed causal relationship between LDL cholesterol and cardiovascular events.

Main Results:

• Multiple trials confirm a strong association between LDL cholesterol and cardiovascular event rates.
• Recent studies using diverse therapeutic agents reinforce this association, indicating a causal relationship between reduced LDL cholesterol and improved cardiovascular outcomes.

Conclusions:

• The 'LDL cholesterol principle' is supported by extensive clinical trial data.
• Ongoing research is anticipated to further validate this causal link, paving the way for individualized dyslipidemia management strategies.
